The technical field TO WHICH the INVENTION RELATES

The present invention relates to a system comprising the base station and the relay station accessing the base station.

The LEVEL of TECHNOLOGY

In the system of LTE-Advanced (advanced long-term development) partnership project to create networks of third generation (3GPP) is considered (see non-patent literature 1) the introduction of relay stations (hereinafter referred to as "nodes RN (relay node)"). Node RN is one of the methods, for example, to increase the communication speed of mobile stations (user equipment (UE)"), located on the edges of a cell, and to promote hundreds of base stations (hereinafter referred to as "nodes eNB (enhanced node B)"). The details of the architecture of the node RN, which is considered in the 3GPP project, disclosed in non-patent literature 2.

Below will be described the circuit of system node RN based on the architecture of the node RN disclosed in non-patent literature 2. Fig. 1 is a diagram showing an example of network configuration when using node RN of the 3GPP project. Base station (eNB) 1 belongs to a core network (CN) 4 operator's mobile network. Backbone network 4 includes the object mobility management (hereinafter - "the object MME) and serving gateway (hereinafter ��gateway S-GW"). Node eNB 1 forms the honeycomb 10 node eNB and relays the traffic between the mobile station (user equipment) 3 and the control network 4. Relay station (RN) 2 is attached to the node eNB 1 via the communication line reverse connection (BL in the figure). The user equipment 3 is attached to the node eNB 1 or node RN 2 through the communication line access (AL1 or AL2 in the figure). Node RN 2 joins the core network CN 4 via the communication line reverse connection (BL) with the node eNB 1. Node RN 2 forms the honeycomb 20 node RN and relays the traffic between the user equipment 3 and the control network 4. The OAM server 5 controls the position of the node eNB 1 and the cell information (using frequency, physical cell ID (PCI), etc.) of the honeycomb 10 node eNB. Line connection return line connection and the access connection will be explained later.

Fig. 2 is a diagram showing a sequence when a node joins RN to the node eNB and core network and starts working cell node RN. Node RN establishes a network connection in operation ("mode user equipment"), similar to the operation of the existing user equipment at the initial startup (step S1). In particular, the node RN forms a joint radio resources management (hereinafter referred to as "RRC") to the node eNB. When a process node RN to join the node eNB � backbone network in the mode of the user equipment is completed, node RN goes to work as a network node (hereinafter referred to as "host mode RN") and manages the hundredth node RN. When a node RN switches to RN, the control method of the communication line reverse connection also switches from the user equipment in host mode RN (step S2).

In the network in which the embedded node RN, the node eNB that supports host mode RN, referred to as the "donor node eNB (hereinafter referred to as "node DeNB")". Here only if you describe the issues unique to the node DeNB, relevant to the connection node RN, the term "node DeNB is used to distinguish it from an ordinary node eNB. In addition, there is user equipment (e.g., user equipment 3-1 in Fig. 1) which joins the node DeNB, referred to as "user equipment node eNB". On the other hand, the user equipment (e.g., user equipment 3-2 in Fig. 1) that is directly attached to the node RN, referred to as "user equipment node RN". In addition, in the case of the description of matters common to the user equipment node eNB and a user equipment node RN, just use the term "user equipment".

When discussing node RN in the 3GPP project has the support request in the future mnogoznachnogo node RN. Mogok�kovy node RN is a method which allows you to connect an additional node RN to the node RN, which is appended to the node DeNB in a cascaded configuration. Here if mnogochasovoj configuration node RN, which is attached to the lower level node DeNB via the air interface, referred to as the "top node RN", and the node RN, which is attached to the lower level of the top node RN, referred to as "lower node RN" to distinguish nodes RN from each other. In addition, there is the radio interfaces between the node DeNB and node RN and between the upper node RN and the bottom node RN are called "lines of communication connections back". Meanwhile, the radio interfaces between the node eNB and a user equipment node eNB and between the node RN and a user equipment node RN are called "lines of communication".

In addition, when discussing node RN in the 3GPP project, it is assumed that the node RN includes as configuration information accession information cell node DeNB to which the node RN can join (see non-patent literature 3). Configuration information attaching includes information to indicate the donor base station cell or sector to which the node RN must join. In particular, the configuration information attaching includes, for example, frequency of a cell node DeNB and the physical cell ID (PCI). Node RN determines �green DeNB, to which node RN must accede, on the basis of configuration information of the connection.

DESCRIPTION of embodiments of

Next, with reference to the drawings will be described embodiments of the present invention. In the drawings, the same elements denoted by the same numbers for references, and repeated explanation of necessity is omitted for clarity of explanation.

The FIRST VARIANT of IMPLEMENTATION

In the first variant implementation of the node RN is temporarily attached to the node eNB and notifies the upper network device, such as an OAM server, state information of the configuration of adhesion. A status notification, for example, includes (i) information indicating the relationship of correspondence between the donor base station designated by the configuration information attaching and joining in the moment, base station, (ii) information indicating whether a valid configuration information of the merger, or (iii) a request for a new configuration information for the connection.

Fig. 3 is a diagram showing an example configuration of a radio communication system comprising a base station 1, retranslation�ing station 2, the mobile station 3 and the core network 4 in accordance with this variant implementation. This variant of the implementation will be described under the assumption that the radio system is a system FDD (full-duplex communication frequency division) - OFDMA, in particular a radio communication system of LTE-Advanced based on LTE system. Base station 1 belongs to the core network 4 to the mobile network operator and relays the traffic between the mobile station 3 and the control network 4. Base station 1 can accommodate relay station 2 and mobile station 3.

Fig. 4 is a block diagram showing an example configuration of the base station 1. As shown in Fig. 4, the radio communication unit 11 generates a downlink signal by performing processing, such as a mapping to resource elements of the OFDM signal (IDFT: inverse discrete Fourier transform), frequency conversion and amplification of the signal over the sequence of symbols of the transmission of the physical channel provided from the processing unit 12 of the data transmission. The generated downlink signal wirelessly transmitted from the antenna. The radio communication unit 11 receives signals in the uplink transmitted from the mobile station 3 or the relay station 2, and recovers the sequence of symbols of the reception.

Block 12 data per�villas maintains the data for the mobile station 3 or the relay station 2, received from the communication unit 14, the buffers established for each mobile station and for each carrier, and forms a transport channel by performing encoding with error correction, the matching rate, interlacing, etc. Next, the processing unit 12 of the data transmission adds control information to the sequence data of the transport channel to form a radio frame. In addition, the processing unit 12 generates transmission data sequence of transmission symbols for each physical channel by performing scrambling and mapping of modulation symbols for data sequence to the radio frame.

Unit 13 handling data reception restores received data for each logical channel from the sequence of symbols of the reception provided from the radio communication unit 11. Data user traffic included in the received received data, and some control data are transmitted in the backbone network 4 through the communication unit 14.

The control unit 15 of relay node controls the timing of transmission and distribution of radio resources related to the data that will be transmitted to the mobile station 3 and the relay station 2. In addition, the control unit 15 of relay node receives information indicating whether to keep the node RN (corresponding to the host mode RN), �otara notified from the relay station 2 through the block 13 data reception. The control unit 15 of relay node performs the configuration of the communication line reverse connection in accordance with the fact whether the relay station 2 node RN.

Fig. 5 is a block diagram showing an example of the configuration of the relay station 2. Relay station 2 is a functional equivalent to the base station 1, if not explicitly defined otherwise. As shown in Fig. 5, the communication unit 21 on the bottom line radio receives signals in the uplink transmitted from the mobile station 3 via the antenna. Block 23 data reception has a functional equivalent block 13 data of a base station 1 and the received data are transmitted to base station 1 through the communication block 24 on the top line radio. The processing unit 22 of the data transmission is a functional equivalent to the block 12 of the data transmission base station 1, and generates a sequence of symbols of the transmission data from the transmission received from connection block 24 on the top line radio and transmitted to the mobile station 3. The communication unit 21 on the bottom line radio generates a downlink signal from a sequence of symbols and transmits the downlink signal of the mobile station 3.

Unit 25 information management configuration accession manages the configuration information p�of soedineniya, related to base station 1. Unit 25 information management configuration accession adopts the configuration information attaching from the base station 1 or the core network 4 via the communication block 24 on the top line of radio communication and the processing unit 22 of the data transmission 22. In particular, block 25 information management configuration accession notifies the OAM server 5 on the state information of the configuration of adhesion. For example, block 25 information management configuration of accession specifies whether the configuration information of the accession on the basis of whether the information (frequency cell node DeNB, the physical cell ID (PCI), etc.) of the base station to which the relay station 2 are actually merged, the information of the donor base station, a cell, or sector, which are assigned through predefined configuration information attaching and want to join a relay station. Unit 25 information management configuration accession notifies the OAM server 5 on the result of determination. The notification may include information indicating whether the correct configuration information connection. The notification may include information that can identify whether the base station to which the fact�Cesky joins relay station, the donor base station, to which should join relay station.

For example, block 25 information management configuration accession may notify the OAM server 5 that relay station 2 does not contain configuration information for accession. The notification may include information that can determine that the relay station 2 does not contain configuration information for accession. Notice of this case also may include a message request new configuration information connection. For example, when the relay station 2 contains configuration information, connection, but the configuration information attaching unavailable due to expiration, etc., block 25 of the control information configuration accession may notify the OAM server 5 that the available information configuration merger is not saved. The notification may include information that can determine that the relay station 2 does not contain the information available to the configuration of adhesion.

Fig. 6 is a block diagram showing an example configuration of the mobile station 3. The radio communication unit 31 receives the downlink signal via antenna. Block 32 data reception, sends the received data, vosstanovlenie�e from a received downlink signal, in block 35 of the buffer. Received data stored in the block buffer 35, is read and used depending on their purpose. Unit 33 controls the data transmission unit 34 of the data transmission and the radio communication unit 31 generates a signal of the uplink through the use of transmission data stored in the block buffer 35, and transmits signal to base station 1 or the relay station 2.

Fig. 7 is a block diagram showing an example configuration of the OAM server 5. The OAM server 5 includes a communication unit 51, which communicates with the control network 4, block 52 data transmission unit 53 of the control data reception, and the block 54 information management configuration accession. Block 53 data reception of receiving data transmitted from relay station 2. When the received data include a notice concerning the status of the configuration information attaching relay station 2 or query configuration information of the connection, the received data is transferred to the block 54 information management configuration accession. Unit 54 information management configuration accession decides whether to notify the relay station 2 information about the configuration of the connection, and sends the configuration information attaching unit 52 data transfer to RET�anslational station 2 on the basis of the result of the decision.

Next, with reference to Fig. 8-10 will be described a specific example of the procedure of notification about the status of the configuration information of the connection in accordance with the first variant implementation.

Fig. 8 is a sequence diagram showing an example of the procedure of notification about the status of the configuration information of the connection in accordance with the first embodiment of implementation. Fig. 8 shows the interaction between the OAM server 5, the control network 4, the base station 1 and relay station 2. Fig. 8 "OAM" corresponds to the OAM server 5; "MIU" corresponds to a core network 4; "DeNB" corresponds to the base station 1; and "RN" corresponds to the relay station 2.

In step S101, the node is looking for a RN node eNB to which the node RN is attached, and performs the formation of the RRC connection with the detected node eNB (step S102). After the formation of the RRC connection node RN performs the procedure to join the network the control network using the MME (step S103) and proceeds to processing of the carrier by the object MME (step S104). In step S104, the procedure of installation of the carrier is performed between the MME and the node eNB. In step S105, the procedure of installation of the carrier is performed between the host node eNB and RN. After completion of the processing of steps S104 and S105 node RN can communicate with the OAM server. Node RN, which can communicate with the server OAM, OAM notifies the server about the status�anii configuration information attaching (step S106).

Fig. 9 is a block diagram of the sequence of operations relating to the operation when the node RN joins the network and notifies the OAM server status configuration information attaching to the first variant implementation. The operation shown in Fig. 9, starts with the search of the node eNB, to which may be joined by the node RN.

In step S201, when the node eNB to which you can join node RN can be detected ("Yes" in step S201), the node RN transmits the configuration request RRC connection is detected, the node eNB (step S202), the process moves to step S203. When a node eNB to which you can join node RN, cannot be detected ("No" in step S201), the node RN terminates without notifying the OAM server status information configuration accession. In step S203 node RN determines whether a node is completed RN to join the network. When a node RN has completed the accession to the network (Yes in step S203), the node RN OAM notifies the server about the state of the configuration information attaching (step S204) and terminates. When the mains connection is not completed ("No" in step S203), the node RN is returned to step S203 to determine whether the completed joining the network.

Fig. 10 is a block diagram of the sequence of operations related to the operation in which the OAM server receives a status notification configuration information PR�connection in the first variant implementation. In step S301, the OAM server determines whether to accept a status notification configuration information connection. When OAM received a status notification configuration information attaching ("Yes" in step S301), the OAM server finishes the receiving operation. When the OAM server did not accept the status notification configuration information attaching ("No" in step S301), the OAM server returns to step S301 to determine whether the notification.

The operation of the base station 1 and mobile station 3 is similar to typical operations and therefore their description is omitted.

As described above, the relay station 2 according to this variant implementation notifies the OAM server 5 on the status of the configuration information for accession after accession to the network via the base station 1. This allows a network operator to determine whether the content of the configuration information attaching appropriate, without having to go to the installed location of relay station 2 and is easy to set up configuration information of the accession, such as the correction of inconsistency in the configuration information attaching or replacing to the correct content. In addition, the network operator could expect to reduce the cost of installation due to ease of configuration information configuration Pris�unity.

The SECOND VARIANT of IMPLEMENTATION

In the second variant of implementation, when the relay station 2 can't join node DeNB designated by the configuration information attaching, relay station 2 connections to another node eNB and notifies the OAM server on the admissibility of the configuration information attaching. Valid state of the configuration information attaching corresponds to the case where a relay station 2 may be the usual way to join the donor base station assigned to the stored configuration information of the connection. On the other hand, the invalid state information configuration accession corresponds to the case where a relay station 2 is not the usual way to join the donor base station assigned to the stored configuration information of the connection. Specific examples of the case when the relay station is not the usual way to join the node DeNB designated by the configuration information of the connection (in other words, the pacing is unsuccessful), include the case in which a node DeNB designated by the configuration information of the accession, is not present near the relay station 2, and the case in which the joining node DeNB designated by the configuration information of the associated�of inane, rejected. Notification of the admissibility of the configuration information attaching may include information indicating whether the configuration information of joining or not, or information indicating that the joining node DeNB designated by the configuration information attaching, is a failure. The notification may also include information that can identify whether the base station to which actually joins the relay station and the donor base station, to which should join relay station.

Below with reference to Fig. ON, 11 and 12 will be described a specific example of the notification procedure on the admissibility of the configuration information attaching the second variant implementation.

Fig. 11A and 11 b are a flow chart providing an example of the procedure of notification of the admissibility of the configuration information attaching the second variant implementation. Fig. 11A and 11B, the eNB 1" corresponds to a base station, which is described in the configuration information attaching, "eNB 2" corresponds to a base station, which is not described in the configuration information attaching, "RN" corresponds to the relay station 2, "OAM" corresponds to the OAM server 5, and "MIU" corresponds to a core network 4. Node RN may detect the node eN of 2 using search. In step S4 01 node RN determines whether the node eNB 1 can be detected based on the configuration information attaching. When a node eNB 1 has been detected and performs the operations of steps S402, S102-S105 and S403-S404 ("A1t1" in Fig. 11A). When a node eNB 1 has not been detected and performs the operations of steps S405 and S101-S106 ("A1t2" in Fig. 11).

When a node RN is found, the node eNB 1 based on the configuration information attaching in step S402, the node RN transmits the configuration request RRC connection is detected, the node eNB and joins the network. The steps S102-S105 show the sequence of operations similar to the operations of the first embodiment, and thus, their detailed description is omitted. Upon completion of the connection to the network node RN starts work cell node RN (step S403) and begins to accept the request for accession from the user equipment node RN (step S404).

When a node RN is not found, the node eNB 1 based on the configuration information attaching in step S4 05, the site is looking for a RN node eNB to which the node RN can join, passes the request to the RRC connection configuration, the detected node eNB 2 and performs an operation to notify the OAM server on the admissibility of the configuration information attaching. The steps S101-S106 show a sequence of operations similar to that of the first embodiment, and thus their detailed description �launched.

Fig. 12 is a block diagram of the sequence of operations related to the operation in which the repeater station 2 joins the network and notifies the OAM server on the admissibility of the configuration information attaching the second variant implementation. In response to the operation detection node DeNB based on the stored configuration information attaching relay station 2 starts the process illustrated in the flowchart of sequences of operations on Fig. 12. In step S501 relay station 2 determines whether the node DeNB to be detected based on the stored configuration information of the connection. When a node DeNB was discovered on the basis of the configuration information attaching ("Yes" in step S501), the relay station 2 generates a RRC connection with the detected node DeNB and joins the network. After transmission of the RRC connection request (step S202), it is determined whether a response to the RRC connection request negative reply (step S503). When a response to the RRC connection request is a negative answer ("Yes" in step S503), the process moves to step S502, which is described later. When a response to the RRC connection request is a positive answer ("No" in step S503), and determines whether the completed connection to the network (step S203).

When a node RN has not completed its accession to the network ("No" in step S203), p�the process returns to step S503, to determine the response to the RRC connection request. After joining the network (Yes in step S203), the relay station 2 starts the honeycomb node RN (step S504). When a node DeNB was not detected on the basis of the configuration information attaching ("No" in step S501), or when it was adopted a negative answer ("Yes" in step S503), the relay station 2 starts the detection of another node eNB, which is different from the node eNB assigned in the configuration information attaching (step S502). After that, the relay station 2 determines the detection result, generates a RRC connection with the detected node eNB and notifies the OAM server information on the admissibility configuration information joining after joining the network. The steps S201-S204 show a sequence of operations similar to that of the first embodiment, and thus their detailed description is omitted.

A block diagram of the sequence of operations related to the operation in which the OAM server 5 receives the notification of the admissibility of the configuration information connection in this variant implementation, similar to the block diagram of the first variant of implementation, and thus, its detailed description is omitted. In addition, the operation of the base station 1 and mobile station 3 is similar to typical operations, as in the first embodiment, osushestvlenie�, and thus, their description is omitted.

As described above, when the relay station 2 according to this variant implementation can not find the base station to which the relay station should join based on the configuration information attaching, relay station 2 is attached to the network through another base station different from the base station assigned through the configuration information of the connection, and notifies the OAM server 5 on the admissibility of the configuration information attaching. Accordingly, even when the configuration of the node DeNB erroneously made in the configuration information attaching pre-configured for relay station 2, the OAM server 5 can find the error without requiring that the operator immediately went to the location of installation of the relay station 2. This allows a network operator to determine whether the content of the configuration information attaching appropriate, and easy to set up configuration information of the accession, such as the correction of a discrepancy in the configuration information attaching or replacing to the correct content.

The THIRD VARIANT of IMPLEMENTATION

In the third variant of implementation, when the relay station 2 does not contain information and com� accession, relay station 2 is temporarily attached to the base station, which is located by searching for and to which you can join relay station. Then, relay station 2 notifies the OAM server 5, information indicating that the configuration information attaching not saved, or request information about configuration connection and receives the configuration information attaching from the OAM server 5. Further, the relay station 2 performs the attach to node DeNB based on the received configuration information of the connection.

Below with reference to Fig. 13-15 will be described a specific example of the procedure of notification about the status (i.e., availability) configuration information attaching in the third variant of implementation. Fig. 13 is a sequence diagram showing an example of the procedure of notification about the availability of configuration information attaching in the third variant of implementation. Fig. 13 "eNB 1" corresponds to a base station, which is located by searching and which can join a relay station, eNB 2" corresponds to a base station described in the updated configuration information attaching, "RN" corresponds to the relay station 2, "OAM" corresponds to the OAM server 5, and "MIU" corresponds to a core network 4.

<> Fig. 13 steps S101-S106 are similar to the steps of the first embodiment, and thus will be described only the differences. After receiving notice regarding the availability of configuration information attaching from node RN OAM server determines that the configuration information of accession was set for node RN (step S601), and sends it to the node RN (step S602). Node RN performs reconnection to the network based on the configuration information attaching. The sequence of operations similar to the steps S102-S105 of the first embodiment, and thus its description is omitted.

Fig. 14 is a block diagram of the sequence of operations related to the operation in which the repeater station 2, which contains no information available configuration joining, join the network, notifies the OAM server 5 about the availability of configuration information of the connection, and receives configuration information attaching, in the third variant of implementation. Stages 5201-S204 are similar to the steps of the first embodiment, and thus will be described only the differences. In step S204, after notification OAM server 5 on availability configuration information attaching relay station 2 moves to step S701 to determine the reception of the configuration information attaching. Examples of notification d�obtaining configuration information attaching may include a notification which indicates that available information configuration merger is not saved, the notification information is temporarily connected base station and notified to request new configuration information for the connection.

When the configuration information attaching adopted from the OAM server 5 in step S701 (Yes in step S701), the relay station 2 generates a RRC connection with the new node DeNB based on the received configuration information attaching and performs an operation of joining the network. The sequence of stages 5202-S203 are similar to the sequence of the first variant of implementation, and thus, its detailed description is omitted. After joining the network relay station 2 starts the honeycomb node RN (step S702) and terminates. When the configuration information attaching not taken from the OAM server 5 ("No" in step S701), the relay station 2 terminates.

Fig. 15 is a block diagram of the sequence of operations related to the operation in which the OAM server 5 receives the notification about the availability of configuration information attaching and sends configuration information to the joining node RN, in the third variant of implementation. Step S301 is similar to phase from the first variant of implementation, therefore, will be described only the differences. When the notice�a notification regarding the availability of configuration information accession received from relay station 2 ("Yes" in step S301), the OAM server 5 determines that the configuration information of accession was set for relay station 2, and sends it to relay station 2 (step S801) and terminates.

The operation of the base station 1 and mobile station 3 is similar to typical operations, as in the first embodiment of implementation, and thus, their description is omitted.

As described above, the relay station 2 according to this variant implementation receives updated configuration information attaching from the OAM server after establishing connection to the network via the base station. Then, relay station 2 performs reconnection to the base station based on the updated configuration information connection. In line with this, there is no need to pre-set configuration information attaching for relay station 2. This makes it easy to set configuration information attaching for relay station 2 and to lower the costs required for the installer. As a result, the network operator can expect a reduction in the cost of the installation.

The FOURTH VARIANT of IMPLEMENTATION

In the fourth embodiment of the when the relay station 2 can't join node DeNB based on the configuration information acquisition�t, relay station 2 is temporarily attached to the other node eNB and receives updated configuration information attaching from the OAM server 5. Then, relay station 2 performs the attach to node DeNB based on the updated configuration information of the connection.

Below with reference to Fig. 16A, 16 b and 17 will be described a specific example of the procedure for notification of the admissibility of the configuration information attaching the fourth variant implementation. Fig. 16A and 16 b are sequence diagrams showing an example of the procedure for notification of the admissibility of the configuration information attaching the fourth variant implementation. Fig. 16 A and 16 In "eNB 1" corresponds to a base station described in the configuration information attaching before updating, "eNB 2" corresponds to a base station, which is not described in the configuration information attaching and found through search, and to which you can join relay station; "eNB 3" corresponds to a base station described in the updated configuration information connection; "RN" corresponds to a relay station 2; "OAM" corresponds to the OAM server 5; and "MIU" corresponds to a core network 4. Node RN may detect the node eNB 2 via lookup.

The steps S101-S106, S401-S405 and S601-S602 similar to the steps from the first, the WTO�wow or third variants of implementation, thus will be described only the differences. Node RN receives the configuration information attaching in step S901 in Fig. 16, generates an RRC connection with the node eNB 3 based on the received information, the configuration of the connection and performs reconnection to the network.

Fig. 17 is a block diagram of the sequence of operations related to the operation in which, when the relay station 2 can't join node DeNB based on the configuration information attaching, relay station 2 is joined to another node eNB, which is different from the node eNB, as described in the configuration information of the accession, and the OAM server 5 updates the configuration information of the accession, in the fourth embodiment of the. Relay station 2 starts the process illustrated in the flowchart of sequences of operations on Fig. 17, in response to the operation detection node DeNB based on the stored configuration information of the connection. The steps S201-S204 and S501-S504 are similar to the steps of the first embodiment or the second embodiment, thus, will be described only the differences.

In step S204 relay station 2 notifies the OAM server 5 on the admissibility of the configuration information attaching and moves on to step S1001 to determine whether the updated configuration information prisoedinenie�. When the updated configuration information accession accepted ("Yes" in step S1001), the relay station 2 generates a RRC connection with the node DeNB based on the configuration information of the connection (step S202). After joining the network relay station 2 starts the honeycomb node RN (step S1002) and terminates. On the other hand, when the updated configuration information merger is not accepted ("No" in step S1001), the relay station 2 returns to step S1001 to determine whether the updated configuration information of the connection.

A block diagram of the sequence of operations related to the operation in which the OAM server 5 receives the notification as to the admissibility of the configuration information attaching, similar to the block diagram of the third variant of implementation, and thus, its detailed description is omitted. The operation of the base station 1 and mobile station 3 is similar to typical operations, as in the first embodiment of implementation, and thus, their description is omitted.

As described above, the relay station 2 according to this variant implementation searches for the base station to which the relay station can join on the basis of the preset information of the configuration of adhesion. When the base station cannot be detected, re�translationa station joins the network through another base station and receives the updated configuration information attaching from the OAM server. Relay station 2 according to this variant implementation performs a new attach operation based on the updated configuration information attaching and attached to the base station described in the configuration information attaching. Accordingly, even when the configuration of the base station erroneously made in the preset configuration information of the accession, the effort that is required for the installer to update the configuration information attaching stored relay station 2 can be reduced, and may be provided with the update. As a result, the network operator can expect a reduction in the cost of the installation.

The FIFTH VARIANT of the IMPLEMENTATION

In the fifth variant implementation, when a node joins RN to the node DeNB based on the configuration information of the joining node RN notifies the node DeNB for the indication of indicating that the mode of the node RN is supported. When a node RN is temporarily attached to the node eNB, node RN does not notify the node DeNB for the indication of indicating that the mode of the node RN is supported.

Below with reference to Fig. 18A, 18 b and 19 will be described a specific example of the procedure for notification of the admissibility of the configuration information attaching to the fifth variant implementation.

Fig. 18A and 18 b are with�Emami sequence, showing an example of the procedure for notification of the availability of configuration information attaching to the fifth variant implementation. Fig. 18A and 18 In "eNB 1" corresponds to a base station described in the configuration information of the connection; "eNB 2" corresponds to a base station, which is not described in the configuration information connection; and "RN" corresponds to the relay station 2. Node RN may detect the node eNB 2 via lookup.

The steps S101-S106 and S401-S405 are similar to the steps of the first embodiment or the second embodiment, and thus will be described only the differences. In step S1101 node RN generates an RRC connection with the detected node eNB 1 based on the configuration information attaching. At this time, a message for the RRC connection configuration includes an indication indicating that the host mode RN supported. After the completion of the accession process node RN to the network node eNB 1 configures the communication line reverse connection (step S1102), and node RN switches from the user equipment in host mode RN (step S1103) and begins work cell node RN (step S104). In step S1105 node RN generates an RRC connection with the node eNB 2, which is different from the node eNB 1 assigned in the configuration information attaching. At this time, the node RN is not includes in the message an indication indicating that the mode of the node R is supported.

Fig. 19 is a block diagram of the sequence of operations related to the operation of the notification to the instructions indicating that the mode of the node RN is supported, in a process in which the relay station 2 according to the fifth variant of the implementation joins the network. The steps S201-S204 and S501-S504 are similar to the steps of the first embodiment or the second embodiment, thus, will be described only the differences.

In step S1201 relay station 2 sends a message to the configuration of the RRC connection, which includes an indication indicating that the mode of the node RN is supported to temporarily connect to the host eNB different from the node DeNB assigned in the configuration information attaching. On the other hand, in step S1202 relay station 2 sends a message to the configuration of the RRC connection, which includes an indication indicating that the mode of the node RN is supported, the node DeNB assigned in the configuration information attaching and moves on to a step S1203, to determine whether the configuration information of the communication line reverse connection, after connection to the network. When information about the configuration of the communication line reverse connection is accepted ("Yes" in step S1203), the relay station 2 starts the honeycomb node RN (step S503). When information is about to�nfiguration line connection return connection is not accepted ("No" in step S1203), relay station 2 returns to step S1203 to determine whether the configuration information of the communication line reverse connection.

Fig. 20 is a block diagram of the sequence of operations showing an example of the procedure of the operation of the base station 1 according to the fifth variant implementation. As shown in Fig. 20, the base station 1 starts the process illustrated in the flowchart of the sequence of operations in response to the reception of the configuration request RRC connection from the relay station 2.

In step S1301, the base station 1 determines whether the request is accepted configuration of the RRC connection. When the configuration request RRC connection is accepted (Yes in step S1301), the base station 1 passes to step S1302 to determine whether a request RRC connection configuration, the indication indicating that the host mode RN supported. When the configuration request RRC connection is not accepted (No in step S1301), the base station 1 returns to step S1301 to determine whether the request is accepted configuration of the RRC connection. When the configuration request RRC connection, as adopted by the base station 1 includes an indication indicating that the mode of the node RN is supported (Yes in step S1302), the base station 1 establishes the RRC connection with the relay station 2 (step S1303), and notifies the relay station 2 information about�AI configuration line connection return connection (step S1304) and terminates. In step S1302, when the instruction indicating that the mode of the node RN is supported, not included in the configuration request RRC connection ("No" in step S1302), the base station 1 establishes the RRC connection with the relay station 2 (step S1305) and terminates.

A block diagram of the sequence of operations related to the operation in which the OAM server 5 receives the notification as to the admissibility of the configuration information attaching, similar to the block diagram of the first variant of implementation, and thus its description is omitted. The operation of the base station 1 and mobile station 3 is similar to typical operations, as in the first variant of implementation, and thus, their description is omitted.

This variant of the implementation illustrates an example in which the base station 1 determines whether or not made the switch to the host mode RN, on the basis of that, does it include a relay station 2, the indication indicating that the host mode RN supported. However, the node RN may send other indication when the mode of the node RN is not supported, different from the instructions indicating that the host mode RN supported.

Description of the above-mentioned variants of the implementation is made on the basis of the second variant implementation. However, even when implementation options based on a variant of implementation differs from the second variation�the implementation can be obtained the same effects.

As described above, when the relay station 2 according to this variant implementation may accede to the base station on the basis of preset information configuration connection, relay station 2 notifies the base station regarding the instructions indicating that the host mode RN supported. On the other hand, when the relay station 2 cannot connect to the base station based on the configuration information attaching and attached to another base station, relay station 2 notifies the base station regarding the instructions indicating that the host mode RN supported. This allows the base station 1 to establish a communication link return connections only with the relay station 2, which starts honeycomb node RN, thereby improving the use efficiency of radio resources of the communication line reverse connection.

ANOTHER VARIANT of IMPLEMENTATION

Relay node scans all channels in the range E-UTRA (terrestrial radio access enhanced UMTS system) via the function of each relay node to find the appropriate cell. Each relay node needs to search only the honeycomb, which is the strongest on each carrier frequency. When the appropriate cell is found that cell is selected, the relay node notifies the network E-UTRAN (network of terrestrial radio access enhanced UMTS system), the information of the donor cell is not stored.

(2) the CELL Selection using the stored information of the donor CELL

This procedure requires the donor cell obtained from a previously configured information of the donor cell or a previously downloaded information of a donor cell, and, when necessary, requested information about the parameter cell. As soon as the relay node finds the corresponding cell, the relay node selects the cell. When there is no corresponding cell is not found or when the relay station cannot connect to the selected cell begins the process of selecting a temporary cell.

SUBSTANCE: description is given of a method and device for switching wireless terminal channels. For this, several communication channels with different physical characteristics are supported in the cell of the base station. Each wireless terminal controls several channels and evaluates several channels at the same time, such that, there can be fast switching between channels. Information on the quality of the channel is sent from each wireless terminal to the base station. The wireless terminal or base station selects the channel, based on the evaluated quality of the channel. By supporting several channels and through periodical changes in channels in different implementation alternatives, the time taken before the wireless terminal finds good or suitable channel conditions is minimised, even if the wireless terminal changes position. Several antennae are used at the base station for simultaneous support of several channels, for example, through control of the directional pattern of the antennae.

EFFECT: reduced delays before wireless terminal finds suitable channel conditions.
