The technical field to which the invention relates.

The present invention generally relates to a mobile station, a network device of a wireless, mobile communication system and method of discrete appointment.

The level of technology

In mobile communication, in order to save battery power of the mobile station, and increasing the resource efficiency network with wireless access, defined a number of States depending on the amount of information (traffic volume).

In particular, these States include the state (CELL_DCH) allocated channel in which communication is performed using the selected channel when the volume of traffic is great, the state (CELL_FACH) common channel in which communication is performed using the shared channel when the volume of traffic is small, and the condition (LL_ or URA_PCH) discrete reception at which the reception of the call light is discontinuous (discrete), when the information for transmission is absent, and the transition between these States occurs in accordance with the volume of traffic that is transferable, as shown in figure 1.

To make the transition between States depending on the transmitted volume of traffic, you need to switch between communication channels. For example, in this case, as shown in figure 2, in which the children ran, includes a mobile station 1 and the network device 2 wireless access between mobile station 1 and the network device 2 wireless access needs to exchange signal of establishment request channel and the signal response of the establishment of the channel.

Figure 3 shows an example of a signal requesting establishment of the channel. This example describes the case of establishing a channel between the mobile station 1 and the network device 2 wireless access, in which a mobile station located in the CELL_PCH state, changes its state to the CELL_DCH.

The network device 2 sends a radio access to the mobile station 1 call information. Mobile station 1 reports data cell (CELL UPDATE), in which the mobile station is in the current time.

Then, the network device 2 wireless access confirms that produced reassign cell, and sends a signal indicating the physical channel to be used for communication (CELL UPDATE CONFIRM).

Next, the mobile station 1 reports that the reconfiguration of the physical channel is performed.

However, the known technical solutions typical of these problems.

As mentioned above, there is the problem of delay control associated with the establishment of the channel, i.e. the delay before data traffic arising from the fact that the transition between States is carried out is carried out depending on traffic volume, subject to the transfer.

In addition, there is a problem of increasing the load on a network device of the radio access control information.

The implementation of the invention

Next, with reference to the accompanying drawings will be described preferred embodiments of the present invention. However, the drawings illustrating embodiments of the invention, the elements performing the same functions are assigned the same reference indices, and re-description of device n is performed.

System for mobile communications, the corresponding variant of implementation of the present invention is described according to figure 4.

The mobile communication system includes a mobile station 100 and the network device 200 of the radio.

The mobile station 100 and the network device 200 radio access bipartite radio communication through shared data (shared data channel) and channel signaling (signaling control chanel).

Next, with reference to figure 5 describes the structure of the mobile station 100, corresponding to the present invention.

The mobile station 100 includes a block 102 transmit and receive data, which serves as a means of discrete reception and contains the antenna unit 104 determine the presence or absence of data and the block 108 request of discrete receiving, with each of the last two blocks connected to the block 102 transmit and receive data, and block 106 demodulation shared data channel, which is used as a means of receiving shared data channel and which is connected to the block 104 to determine the presence or absence of data.

Block 102 transmit and receive data transmitting and receiving data. For example, the block 102 transmit and receive data when performing discrete reception, performs intermittent reception only channel signaling.

Block 104 to determine the presence or absence of the data sets is an act of presence or absence data, addressed to the mobile station 100 when you are receiving using signaling path.

Block 106 demodulation shared data channel performs demodulation of the shared data channel received in a certain period of time corresponding to the signaling path, when installed in the fact that the availability of data addressed to the mobile station. That is, when it is established that there is data traffic addressed to this mobile station, unit 106 demodulation shared data channel produces the respective shared data channel.

When the continuous reception shared data channel, the block 108 discrete request reception determines whether the transition to a discontinuous reception (discontinuous reception), and, if it is determined that the transition to the discrete pattern is required, the unit 108 discrete request reception using the signaling path of the ascending line, transmits to the network device 200 radio access information to request intermittent reception.

Further, according to Fig.6, describes the network device 200 radio access, the corresponding variant of implementation of the present invention.

Network device 200 radio access includes the transmitting unit 202, and the block 208 notice of discrete reception unit 204 managing shared data channel that serves as among the means of planning data, and the block 206 control channel signaling, which is connected with the transmitting unit 202. In addition, the network device 200 contains a radio access unit 210 controls the discrete intake, coupled with block 204 managing shared data channel and to block 206 control channel signaling, as well as block 212 definition of the discrete intake connected to the control block 210 discrete and reception unit 208 notice of discrete appointment.

Block 212 define discrete reception manages at least one of the following values: sync started a discrete reception time interval of the discrete intake and digital reception. Block 212 define discrete method establishes a discrete reception of the mobile station, which has changed its state to the discrete state of reception, so that the discrete intake does not overlap with other mobile stations. For example, the block 212 define discrete admission as a discrete reception selects at least some of the channels belonging to the channel signaling. In addition, the block 212 define discrete reception saves the selected channel discrete reception unit 210 controls a discrete appointment.

Block 208 notice of discrete receiving oolset mobile station channel digital reception mounted unit 212 define discrete appointment. For example, block 208 notice of discrete receiving reports of at least one of the following values: time, which must be discrete reception, the time interval of the discrete intake and the channel that should be taken when performing a discrete appointment.

Block 210 control of discrete controls the reception state of each mobile station, for example, manages the reception state of a shared data channel and the status of discrete appointment. For example, the control block 210 discrete intake determines whether to produce a change of state on condition discrete appointment. The control block 210 discrete intake controls the timing of the beginning of the discrete intake and discrete reception and informs the aforementioned block 206 control channel signaling point in time at which the signaling path established by block 212 define discrete reception can be assigned to a mobile station located in the state of a discrete appointment.

Block 206 channel control signaling carries out scheduling based on the received synchronization data.

Block 204 managing shared data channel carries scheduling in accordance with the priorities of the mobile stations, the volume of the and data and similar factors.

As shown in Fig.7, the present invention deals with the case in which the network device 200 radio access includes the function of the control device and the function device is a base station. In this case, for example, device 220 radio control units 210 control of discrete reception unit 212 define discrete and reception unit 208 notice of discrete reception, while the device 230 a base station equipped with block 204 managing shared data channel and the block 206 control channel signaling.

In addition, the network device 200 radio may be in the form of device 220 radio and device 230 of the base station.

Next, with reference to Fig, discusses the reception state of the mobile station 200 and the reception status shared data channel and the signaling path.

Conditions of reception of the mobile station 100 are the reception state of the shared channel (continuous intake) and the state of the discrete (discontinuous) receive signaling path. In the mobile station 100, the transition from the reception status of the common channel to a discrete state of the reception channel signaling is performed according to the instruction from the network device 200 of the radio.

In addition, the transition from the discrete intake channel signalling to state is s continuous receive a common channel is performed, when the mobile station 100 receives data downlink.

When the mobile station 100 is in a state of discrete receiving channel signaling, when a data downlink network device 200 of the radio transmits data downlink coordinated in time with the synchronization signals discrete reception of the mobile station.

In this embodiment of the invention, when there is data to or receiving data for transmission, the mobile station 100 included in the reception state of the shared data channel.

Further, according to Fig.9, describes the use of the mobile station and describes the algorithm of the mobile station 100 in the reception state of the shared data channel.

Block 104 to determine the presence or absence of data to mobile station 100, which is in the reception state of the shared data channel, constantly receiving channel alarm and checks whether the identifier of the given mobile station in the received channel signal (step S902). The ID of the mobile station may be included in the signaling path directly, or may be detected in the signal, with which it has carried out certain calculations, using the ID of the mobile station.

If the identifier of the given mobile station is not included (step S902: NO), then the block is 104 determine the presence or absence of data makes the reception channel signaling on the next cycle synchronization. That is, the algorithm returns to step S902.

On the other hand, if the identifier of the given mobile station is enabled, the unit 102 to transmit and receive data produces receiving shared data channel corresponding quantum synchronization (step S904).

In the reception state of the shared data channel, when within a certain time there is no data addressed to the mobile station in the ascending or descending line, block 212 define discrete receiving network device 200 radio access determines that the mobile station 100 needs to transition into a state of discrete receiving channel signaling. Block 208 notice of the discrete intake directs the mobile station an instruction to transition to the state of a discrete appointment.

In this case, for example, block 204 managing shared data channel of the network device 200 performs radio access measurement to determine the presence or absence of data in the downlink. In addition, the block 108 discrete request reception belonging to the mobile station 100, performs the measurement, determining the presence or absence of data in the uplink communication. For example, if the measurement result of the presence or absence of data in the uplink connection is established, that for a certain period of time to transmit data are missing, nl is to 108 query discrete reception included in the mobile station 100 notifies the network device 200 radio access that data to be transmitted, not available.

Block 212 define discrete reception, included in the network device 200 radio that receives information indicating the absence of data for transmission through the block 208 notice of discrete reception transmits a message indicating that the status should be changed to a condition of discrete receiving signaling path.

In the mobile station 100, which receives this instruction, it proceeds from a state of continuous reception of the common channel to a discrete state of reception of the signaling path, as shown in figure 10.

Further, according to 11, describes the use of the mobile station 100.

In further describes the scheme of operations of the mobile station when it becomes discrete reception of the signaling path.

First block 102 transmit and receive data to mobile station 100 checks whether the mobile station 100 in the discrete state of reception (step S1102).

As shown in Fig, the mobile station 100, as in the discrete state of reception of the signaling path, receives the signaling path intermittently, in moments of synchronization specified network device 200 of the radio.

If the mobile station is not in a state diskretnog is received (step S1102: NO), then the process returns to step S1102.

On the other hand, if the mobile station is in a state of discrete reception (step S1102: YES), and performs intermittent reception unit 104 determine the presence or absence of data produces determining whether data addressed to the mobile station (step S1104).

If there is no data addressed to the considered mobile station, that is, in the data transmission on the downlink, not included the ID of the mobile station while the mobile station transmits a discrete reception channel signaling (step S1104: NO), the process returns to step S1102. In this case there is no status change on the reception state of the shared data channel. Mobile station 100 may receive at least part of the signaling path in accordance with the instruction from the network device 200 of the radio.

On the other hand, if there is data addressed to the mobile station, i.e. the identifier of the given mobile station is placed in the signaling path, the reception of which is discontinuous manner (step S1104: YES), the mobile station performs reception of the corresponding shared data channel (step S1106). In this case, the transition occurs from the state of the discrete intake channel signalling to the continuous reception state shared data channel.

An example of the consequences of the successive operations of the mobile station is according to Fig, in which the mobile station switches from the state of the discrete intake channel signalling to the continuous reception state shared data channel.

Block 206 control channel signaling network device 200 radio access makes the call signaling path (step S1202).

The mobile station 100 detects its own ID, and enters a state of continuous reception shared data channel (step S1204).

The mobile station 100 starts receiving the shared data channel at some point synchronization (step S1206).

In accordance with this embodiment of the invention there is no need for procedures for transition between States and switching channels that have been discussed in relation to figure 3, and the network device 200 of the radio may begin to transmit data on the downlink immediately after the call to the mobile station 100 according to the signaling path, so that switching channels is unnecessary.

In addition, in accordance with this embodiment of the invention, due to the lack of switching communication channels between the time interval for normal reception and the time interval for the discrete intake, may be a direct transfer of data, even if their appearance occurs during a discrete appointment. Thus, it can be reduced for Erika management - the delay to the start of data reception of the mobile station. As a result, the switching procedure of the communication channels becomes unnecessary, so that the load on management for network devices of radio access may be reduced.

In addition, since it is necessary to perform intermittent reception only channel signaling, switching to a discrete state of the reception channel of communication is also not required. Moreover, since the data reception can be performed without setting procedures of the channel even when the transmitted data, the delay control delay to the start of the reception data and load management for network device wireless access can be reduced.

Mobile station, a network device of a wireless, mobile telecommunications system and method for digital reception corresponding to the present invention can find application in mobile communication systems.
