The technical field to which the invention relates

The present invention relates to wireless communications, and more particularly to a method for switching between multiple levels of reception, in order to minimize power consumption of the user equipment and to improve the quality of service in wireless systems.

The level of technology

System in accordance with the technical conditions of the partnership project in the field of technology of the 3rd generation 3GPP - 3rd generation partnership project), based on a radio access technologies, like broadband multiple access code division multiplexing (WCDMA - wideband code division multiple access), are widely used all over the world. High-speed packet access downward channel (HSDPA - High speed downlink packet access), which can be defined as the first evolutionary stage WCDMA, provides 3GPP very competitive radio access technology in the medium term. However, as the needs and expectations of users and service providers are constantly increasing and there is a continuous development of competing radio access technologies, new technical developments in the field of 3GPP must ensure competitiveness in the future. Reduced cost per bit, increased service availability, flexible use of frequency bands, a simple architect is RA and the public interface, low power consumption of the user equipment, and the like are nominated as requirements for next generation communication systems.

Search call is a network activity that causes one or more user equipment for any purpose. In addition to the basic function of providing network opportunities to search for a user equipment of the search call also has the function of providing the user equipment and the possibility to go from standby mode. In normal times, the user equipment is in idle mode. User equipment wakes up only when receiving from the network channel search call and performs the requested network effect.

In idle mode user equipment must periodically Wake up and confirm, do the channel search call. The revival of the user equipment at periodic intervals, not continuously, is called discontinuous reception (hereinafter referred to as 'DRX' - discontinuous reception).

In contrast to the base station, the user equipment operates using the battery. If the battery of the user equipment is not charged continuously, the duration of the user equipment is limited to the. To increase the duration of the operation of the user equipment shall be configured to minimize the power consumption at the time when the user equipment actually does not transmit or receive data.

There are various ways to save power consumption. The first way, which is consistent with the design criteria of the project, established due to the limited battery capacity of the user equipment is to minimize the time spent by user equipment on an acknowledgement that they have received on the user's equipment any data. Minimizing the time required of the user equipment on the control channel, which notifies you of incoming data to the user equipment, such as a channel search call. The second way is to pass the user data to the user equipment with a minimum delay time when there is user data that must be transferred from the network to the user equipment. The more time passes from the moment when the user data are generated by the network until the user data is actually received at the user equipment, the pain is E. deteriorating quality of service, perceived by the user. User data received over the network, must be transmitted to the user equipment as quickly as possible to minimize the delay time. However, in order to reduce the delay time of the user equipment to monitor channel t search call, such as the channel search of the call, should be increased.

Although the first and second methods described above, are the necessary conditions for the optimal functioning of the user equipment, they offer conflicting conditions.

There is a need for a method to simultaneously satisfy both of these conditions at the user equipment and the network.

The implementation of the invention

1 is a structural diagram showing a wireless communications system. It may be a network structure of an improved universal system for mobile telecommunication (E-UMTS evolved universal mobile telecommunications system). E-UMTS may be cited as the system as LTE (Long Term Evolution Long - term Development). The wireless communication system is widely used to provide a variety of communication services such as voice, packet data, and the like.

Refer to Figure 1, the network terrestrial radio access enhanced UMTS (E-UTRAN - evolved-UMTS terrestrial radio access network) includes a base station (BS) 20. The user equipment (ON) 10 can be stationary or mobile and may be cited as using another terminology, such as mobile station (MS), user terminal (ut), subscriber station (AP), a wireless device or something like that. The BS 20 generally is a fixed station that communicates with the 10 and may be cited as using a different terminology, in the example, as the enhanced B-node (eNB - evolved-NodeB), base transceiver system (BPS), access point, or something like that. Within the scope of the BS 20 may be one or more cells. Between the BS 20 may be used in an interface for transmitting user information flows or control of information flows. Later in this document descending line of communication implies communication from the BS 20 to 10, and the rising line of communication implies communication from the 10 to the BS 20.

BS 20 provides a contact point on the plane and user plane control. BS 20 are connected to each other through the X2 interface, and the adjacent base station 20 may use a network with a cellular structure, in which always the X2 interface.

The BS 20 is connected to the enhanced packet core (EPC - evolved packet core), more specifically to the gateway 30 access (SM)via the S1 interface. SM 30 provides the contact point of the communication session control functions mobility of the user equipment 10. Among the BS 20 and SM 30 many nodes can connect to each other in the ratio of "many-to-many via the S1 interface. SM 30 can be separated into a part for handling user information flows and processing of control information flows. In this case SM for processing information flows new user who I can communicate with the SM for processing control information flows through the new interface. SM 30 also referred to as an element of mobility management/element plane user (elm/EPP).

Layers of a radio interface Protocol between the AT and the BS can be divided into L1 (first layer), L2 (second layer), and L3 (third layer)based on three lower layers of an interaction model of open systems interconnection (OSI - open system interconnection), which is well known in communication systems. The physical layer corresponding to the first layer, provides a way of transmitting information using a physical channel. The radio resource control layer (RRC - radio resource control), located on the third layer, manages the radio resource between the software and the network. To this end, the RRC layer exchanges RRC messages between the software and the network. The RRC layer can be distributed among network nodes, such as BS 20, SM 30, and the like, or may be placed only on the BS 20 or SM 30.

The air interface Protocol includes a physical layer, data link layer and network layer in the horizontal plane. Or, otherwise, the air interface Protocol includes a user plane for transmitting information in the form of data and control plane for transmitting control signals in a vertical plane.

2 is a structural diagram showing the control plane of a radio interface Protocol. Figure 3 is a structural diagram that shows the user plane Protocol for the radio interface. They show the structure of a radio interface Protocol between E-UTRAN based on the technical requirements of 3GPP-radio access network.

Refer to Figure 2 and 3, the physical layer, i.e. the first layer provides information transfer to the upper layer using a physical channel. The physical layer is connected to the control layer the medium access (MAC - medium access control), i.e. the upper layer, through a transport channel. The data is transferred between the MAC layer and the physical layer through the transport channel. Between different physical layers, i.e. the physical layer of the transmitter and the physical layer of the receiver, the data is moved through the physical channel.

The MAC layer of the second layer provides a service for the layer control radio channel (RLC - radio link control), i.e. the upper layer, through a logical channel. The RLC layer of the second layer provides reliable data transfer. The function of the RLC layer can be implemented in the form of a functional block within the MAC layer, and in this case, the RLC layer may be absent, as shown by the dotted line.

The Protocol of the packet data convergence (PDCP - packet data convergence protocol) of the second layer performs header compression to reduce the size of the packet header IP (Internet Protocol interworking), containing a relatively large and unnecessary control information, so that efficiency is actively send packets at the site of the radio narrow bandwidth when transmitting IP packets, for example, IPv4 or IPv6 packets.

The radio resource control layer (RRC) of the third layer is defined only in the control plane. The RRC layer controls the logical channel, transport channel and physical channel in relation to configuration, reconfiguration and release of radio channel (RB radio bearer). RB enters the service provided by the second layer for data transfer between the software and E-UTRAN. RB provides a logical path provided by the first and second layers of radioprotecao, to transfer data between the software and E-UTRAN. As a rule, the installation of RB means the process of determining the characteristics of the layers radioprotecao and channels required to provide specific services and regulation of specific parameters and procedures of the layers radioprotecao and channels.

Transport channel downlink data from the network includes a broadcast channel (BCH - broadcast channel) for transmitting system information and a downlink composite channel (DL-SCH is a downlink-shared channel) for transmitting user information flows or control messages. Information flows for multicast or broadcast services or control messages can be transmitted on the DL-SCH or on a selected downstream channel multicast (DL-MCH - downlink multicast channel). Transport channel uplink communication data is x from the network includes a random access channel (RACH - random access channel) for transmitting an initial control message and an uplink composite channel (UL-SCH - uplink-shared channel) for transmission to other user-defined information flows or control messages. Channel search call (PCH - paging channel) to transmit information retrieval call is also included in the transport channel uplink connection.

Figure 4 is an example showing a method of receiving data according to a variant implementation of the present invention.

Refer to Figure 4, has at least two levels discontinuous reception (hereinafter referred to as DRX). The DRX level determines AT the time of confirmation of receipt of data on the downlink. The DRX level is the level of technique to reduce power consumption. The level determines the DRX period to confirm the receipt of data on the downlink, i.e. the period of the DRX level. ACCORDING confirms the receipt of data on the downlink in each period of the DRX level. The time period of the DRX level, which confirms the receipt of data on the downlink, called the event a search call. Event search challenge can be repeated in each period of the DRX level.

The interval during which radioresource allocated for, is called a time interval of transmission (TRS), and the event is e search call may specify the first TRS in the period of the DRX level.

The period of the DRX level of each DRX level may differ from other periods of DRX levels. There are many levels of DRX, with periods of DRX level that is different from each other.

Further in this document it is assumed that the software has two levels of DRX, i.e. the first DRX level and the second DRX level, and the period of the DRX level of the first DRX level longer than the period of the DRX level of the second DRX level. However, the number of DRX levels is not limited to two and may be three or more.

ON awakening in the first subcycle of the first DRX level and receives channel planning. In this document, channel planning means the channel, which specifies the data arrives at or passes the signal search call. Channel planning can be a channel indicator search call (PICH - paging indicator channel), a channel search call (PCH), by channel L1/L2 control and the like.

In figure 4, because can not get their information from the first subcycle of the first DRX level, it enters standby mode during the remaining period of the DRX level.

Further, UPON awakening in the first subcycle of the first period of the DRX level and receives channel planning. If BS is the first data D1 to transmit, the BS informs ON the existence of the first data, together with the starting point of the first period of the DRX level, channel planning. BY including the onset, it was planned and works at the level of continuous reception (Non-DRX). The level of Non-DRX may also be called the level of continuous reception. The level of Non-DRX FOR continuously receives the channel used for receiving data, or channel, indicating on ON on receipt of the data that will be transmitted. If BS is the first data D1 to transmit, the BS informs ON the existence of the first data channel planning. ACCORDING recognizes channel planning is included in the level of Non-DRX and receives the first data D1, as indicated by information planning.

After completion of the transmission of the first data D1 BS transmits the DRX indicator on to report that more should not continue to take the channel planning.

The DRX indicator instructs to move to a new level of acceptance. The DRX indicator becomes the condition for the transition to move ON to a new level. A new level of acceptance can be a new DRX level or a new level Non-DRX. The BS may request to move from the level of the Non-DRX in the first or the second DRX level through the DRX indicator. In the example depicted in figure 4, the DRX indicator instructs to switch to the second DRX level, and moves from the level of Non-DRX for a second DRX level, as indicated by the DRX indicator. If the second DRX level is not set, can go to the first DRX level.

When operating in the second DRX level ON Probus is moved in the first subcycle of each period of the second DRX level and receives channel planning. If BS is the second data D2 to transmit, the BS informs ON the existence of the second data D2 together with the period of the second DRX level for channel planning. ACCORDING recognizes channel planning is included in the level of Non-DRX and receives the second data D2. Since the period of the second DRX level is shorter than the period of the first DRX level, the BS may transmit the second data D2 in additional short intervals.

If can not get their information from the channel planning for the remaining phases of the period of the second DRX level, does not accept the channel planning in the remaining period. ON awakening in the first subcycle of each period of the second DRX level and receives channel planning. If it cannot get its information from the first subcycle period of the second DRX level, does not accept the channel planning during the remaining period of the second DRX level corresponding to the second DRX level.

If a certain condition when operating in the second DRX level, can again go to the first DRX level. In this example, the drawing shows that, as soon as the BS ends the second phase of the period of the first DRX level, i.e. starts the third phase of the period of the first DRX level, terminates in the second DRX level and goes to the first DRX level.

Between the network and are defined BY at least two or more levels of reception. The level is receiving means receiving status, which can be a level in a Non-DRX or DRX level. The condition of the drill can move between levels of acceptance.

Transitions between levels of reception is implemented by explicit command or clear the alarm.

One example of the conditions of transition to the transition between levels is what takes the DRX indicator. The DRX indicator may prescribe to move to another level DRX. In addition, the DRX indicator may prescribe BY jump in the level of Non-DRX. The DRX indicator may contain information that indicates at what level of reception of a reception should go ON. If one accepts the DRX indicator, according to which the software should go to a specific level DRX, enters the DRX level prescribed in the DRX indicator.

The DRX indicator may include information indicating when to switch to a new DRX level. The DRX indicator may contain the start time of the new DRX level. If the DRX indicator contains information indicating when should switch to the new DRX level, can move to a new DRX level during a prescribed this information.

The DRX indicator can be transmitted over the channel L1/L2 control. Alternatively, the DRX indicator can be transmitted by the MAC message, and the DRX indicator may be contained in the MAC header. The DRX indicator contained in the MAC is agolove, can be contained in the Protocol data unit (PDU - protocol data unit) MAC-level in the form of control information. The DRX indicator can be transmitted through RRC message.

Another example of switching is that installation takes is a new level of acceptance. The BS may inform the installation is when the network and initially connect or reconnect. Setting value may be the value relating to the period of the DRX level used at each level DRX. In the alternative, the setting value may be information that indicates when the period of the DRX level on each DRX level. Setting value can be transmitted through RRC message.

Another example of switching is that BY not receiving data over a certain period of time, or is not notified within a certain period of time of receipt of the data, which should take, through the channel prescribed BY to receive data, or channel announcing the existence of data that must be transmitted.

Another example of switching is that transmits data on channel uplink communication. This happens when transmits a message for requesting radioresource for channel ascending line or lane which provides user data or control message channel uplink connection.

Another example of the conditions of transition is the beginning of a new period level DRX DRX level, which is different from the DRX level, which is at the present time.

Another example of the conditions of transition is the beginning of a new period of the DRX level another level DRX with the period of the DRX level, which is longer than the period of the level DRX DRX level, which is at the present time.

If there comes a condition of transition and moves to a new DRX level, the new DRX level can be applied with a certain time. This time may be a time that begins a new period of the new DRX level. When moving to a new DRX level, can support used in the present DRX level until the start of the new period of the new DRX level.

At each level DRX accepts channel planning, which prescribes to accept data or reports about the existence of data that must be passed on, in a pre-specified time periods. After receiving the channel planning, if notified of the existence of data to, or receives information regarding radioresource, which should take, can go to a new level. FOR example, can go to the level of Non-DRX. If the BS informs about the fact that there is no data coming in ON, or neopalimaya on information on radioresource, who should accept, not accept channel planning to the next predefined time period based on the set value DRX.

In each level DRX BS can transmit the DRX indicator requiring to accept the data or making the team get ready to receive data only in predefined time periods for channel planning. After receiving the DRX indicator can move to the next level. For example, the network and can go on to a level Non-DRX. If the BS informs about the fact that there is no data coming in, or is not notified of information regarding radioresource, which should take, the BS may not transmit the DRX indicator to the next predefined time period based on the set value DRX.

The predefined time period may be an event search call. Event search call is repeated in each period of the DRX level. Event search call is the first TRS period of the DRX level.

Later in this document many levels of reception and the transitions between them are described in the examples.

The network and can set three levels of reception. These three levels include the level of Non-DRX and two DRX level (the first level and the second DRX level DRX). Network and move from the current level of reception in the following the respective receive level, if a certain condition. Then they establish a method of receiving channel downlink, based on the setting values set for each of the levels of the reception.

The level of Non-DRX FOR continuously receives channel planning, prescribing to accept data or informing about the existence of data that must be transferred. The level of Non-DRX FOR continuously receives channel planning in each time period.

In the first DRX level ON channel takes planning each event search call based on the set value DRX (period of the DRX level). If you specify the existence of data that must be transmitted to, or received information regarding the allocation of radioresource that would need to take during the event search call, can go to the level of Non-DRX.

In the second DRX level ON channel takes planning, prescribing receive data with each event search call based on the set value DRX. If you specify the existence of data that must be transmitted to, or received information regarding the allocation of radioresource, which should take during the event search call, can go to the level of Non-DRX. Alternatively, it may move from the second DRX level to the first level is DRX.

In the second DRX level ON channel takes planning, prescribing receive data with each event search call based on the set value DRX. If you specify the existence of data that must be transmitted to, or received information regarding the allocation of radioresource, which should take during the event search call, can perform continuous intake only during the relevant period of the second DRX level. Throughout the relevant period can take channel planning.

One example of the conditions of transition to moved from the level of the Non-DRX second DRX level, is what takes the DRX indicator instructing a transition to the second DRX level, from the BS. Another example is that BY not receiving data from the BS within a certain period of time or does not receive scheduling information. Another example is that installation takes is for a new Non-DRX. Another example is that while not receiving data over a certain period of time or information regarding the planning data from the BS, reaches the first subcycle period of the second DRX level.

One example of the conditions of transition to moved from the second DRX level in the first UB is the tier DRX, is that not receiving data from the BS within a certain period of time or does not receive scheduling information. Another example is that BY not receiving data from the BS or does not receive information on planning data. Another example is that reaches the first subcycle period of the first DRX level. Another example is that takes the DRX indicator, instructing the switch to the first DRX level, from the BS. Another example is that installation takes is for a new Non-DRX.

If has many levels of acceptance, power consumption can be regulated depending on the amount of user data transmitted. In the example, a typical visit to the web pages while browsing the Internet, after loading the web page, the user moves to the next page when viewing the screen for quite a long time. These web pages are transmitted to the user all together. However, some data, such as multiple images, forming a web page, is delayed in transmission to the user depending on the situation. In this situation works in the level of Non-DRX, if the screen is transmitted at one time, the next step is transferred to the second DRX level, in which some data can zaderjyvat the Xia, and, finally, enters the first DRX level, in which the transfer of data is almost useless, while the user browses the web page. If the number of DRX levels is large, the consumed power can be reduced by using differentiation DRX in accordance with the flow of user data. In addition, deterioration in the quality of service perceived by the user, can also be minimized.

Figure 5 is an example showing a method of receiving data according to another variant implementation of the present invention. To move between levels used a time counter.

Refer to Figure 5, initially located in the first DRX level. If BS is the first data D1 to transmit, the BS informs ON the existence of the first data, together with the period of the first DRX level, channel planning. ACCORDING recognizes channel planning is included in the level of Non-DRX and receives the first data D1.

After completion of the transmission of the first data D1 starts the time counter of the transition. If not take your information over the channel planning before the end of the count time of transition, may move to another level. In this example, when the meter operation time of transition, moving from the level of Non-DRX for a second DRX level. Duration of work the s counter time of transition can be stored on the storage device, can be reported ON by the BS or may be appointed BY and reported to the BS.

6 is an example showing a method of receiving data according to another variant implementation of the present invention. To move between levels used many time counters.

Refer to Fig.6, initially located in the first DRX level. If BS is the first data D1 to transmit, the BS informs ON the existence of the first data, together with the period of the first DRX level, channel planning. ACCORDING recognizes channel planning is included in the level of Non-DRX and receives the first data D1.

After completion of the transmission of the first data D1 starts the first counter time of transition. If not take your information over the channel planning before the end of the first time counter move, can move to another level. In this example, when the first count time of transition, moving from the level of Non-DRX for a second DRX level.

When goes to the second DRX level, starts the second counter time of transition. If not take your information over the channel planning before the end of the second time counter move, can move to another level. In this example, when the second counter is the time of transition, BY moving from the second DRX level to the first DRX level.

7 is an example showing a method of receiving data according to another variant implementation of the present invention. Prepared pre-specified number of periods DRX level to move between levels of acceptance.

Refer to Fig.7, initially located in the first DRX level. If BS is the first data D1 to transmit, the BS informs ON the existence of the first data, together with the period of the first DRX level, channel planning. ACCORDING recognizes channel planning is included in the level of Non-DRX and receives the first data D1.

After completion of the transmission of the first data D1 goes ON to the second DRX level. The transition can be made according to the DRX indicator or time counter. If not takes its scheduling information for a pre-determined number of periods of the second DRX level, goes to the first DRX level. In this example passes in the first DRX level after passing three period of the second DRX level.

The number of periods DRX level may be a value that is known in advance and BS and software, or may be provided by the BS or Vice versa.

Fig is an example showing a method of receiving data according to another variant implementation of the present invention. It represents the case when ballyorgan DRX is not synchronized with the second DRX level.

Contact Fig, if not accept its scheduling information for a predefined number of periods of the second DRX level, it goes to the first DRX level. In this example passes in the first DRX level after passing three period of the second DRX level. At this stage moves in the first DRX level immediately after it has passed the pre-specified number of periods of the second DRX level.

Fig.9 is an example showing a method of receiving data according to another variant implementation of the present invention. It is a case where the first DRX level is synchronized with the second DRX level.

Refer to Fig.9, despite the fact that does not accept its scheduling information for a predefined number of periods of the second DRX level, it continues to reside in the second DRX level up until the first DRX level is not synchronized. Assume that the number of periods of the second DRX level of the selected three, and if the first DRX level is not synchronized even after three passed through the period of the second DRX level, work continues in the second DRX level until the start of the new period of the first DRX level. In this document, the specified number of periods of the second DRX level refers to the minimum number of repetitions.

Figure 10 is an example showing the method d is the R according to another variant implementation of the present invention.

Refer to Figure 10, a pre-defined starting point of the period of the DRX level. Accordingly, despite the fact that accepts the DRX indicator after completing transmission of the first data D1, it does not stop immediately receive channel planning, and maintains the level of Non-DRX until then, until you reach the next period of the second DRX level. After that enter the second DRX level in conjunction with the beginning of the period of the second DRX level. Despite the fact that the BS transmits the DRX indicator instructing a transition to the second DRX level after transmission of the first data D1, moves from the level of Non-DRX for a second DRX level at that point in time, when it starts the next period of the second DRX level.

Then, during operation in the second DRX level, if the software takes the information in the first phase of the period of the second DRX level on the channel planning, it again goes into the level of Non-DRX.

The network and can know in advance the starting point and/or interval period of the DRX level. Or the network may send information regarding the starting point and/or interval. If the starting point and/or interval level DRX installed when the transition from one level to another level, you know, when moves to another level and receive from him, while accepts the first subcycle of the new level. If the condition is La transition from reception to a new level of acceptance, BY not immediately goes to a new level of acceptance, and moves together with the starting point of the newly installed. That is, BY not moving to a new level of acceptance at any time, and a new level of acceptance begins to apply only to the pre-set time period, based on the starting point and phase of each level.

ON who the second data D2, moves from the level of the Non-DRX first DRX level when you begin a new period of the first DRX level. Staying in the reception, can move from the reception to the new DRX level if reached a new starting point of the DRX level than the current level. For example, when working on the second DRX level and is a certain condition is achieved if the new starting point of the first DRX level, moves to the first DRX level. In this example, a condition may be that BY not accepting their scheduling information within a certain period of time in the current level.

If the start point of each DRX level is set in advance, even if the software does not accept a separate indicator, such as the DRX indicator and the settings and BS are not consistent with each other, the impact of this mismatch can be minimized. Despite the fact that skips the indicator DR in the reception, BY spending as much battery power as the period of the first DRX level to the maximum. Consequently, and BS is helpful to know in advance the starting point of the period of the DRX level. For this purpose, when a specific condition and is moving into a new DRX level, not immediately goes into a new DRX level, and should only go together with the starting point of a new period of the DRX level.

For example, the functionality, described below, are also possible.

1) BS sets the period of the first DRX level and the period of the second DRX level to the software.

2) In the first subcycle period of the first DRX level checks the channel L1/L2 control to confirm that they have received the data.

3) If the data entered BY,

(1) receives data on the basis of schedule information, and

(2) continuously monitors the control channel L1/L2 until it is accepted DRX indicator, and if the BS informs about the existence of data on the control channel L1/L2, receives data on the basis of schedule information.

(3) If accepted indicator DRX,

((1)) starts in the second DRX level to reach the next period of the first DRX level, and

((2)) takes the first subcycle of each period of the second DRX level when operating in the second DRX and checks the channel L1/L2 control to confirm that they have received the data.

((3)) If it is confirmed that the data Postup is whether, ON

i) receives data on the basis of schedule information, and

ii) receives the channel L1/L2 control until there is data to receive.

((4)) If confirms that nothing is planned, by channel L1/L2 control is the level of expectation, until you reach the first subcycle or period of the second DRX level period of the first DRX level, whichever is reached first.

4) If no data is entered in the first subcycle period of the first DRX level, the software operates in standby until it reaches the first subcycle of the next period of the first DRX level.

When operating in the DRX level, if required to accept data or notified about the existence of data for a receive channel planning or this goes to the level of Non-DRX. After that, if accepts the DRX indicator, it goes to a new level of reception, for example in a new DRX level. BY may update the currently used setup value of the DRX on the newly adopted installation DRX value.

BS may additionally inform you about when the new installation is DRX starts to apply. When accepts the new setting value DRX, the new setting value is used since the time prescribed in BS.

The level of Non-DRX, in other words, similar to zero-the th period of the DRX level. Accordingly, if the new value of the period of the DRX level to ON is set to zero, can work at the level of the Non-DRX until it is set to the new value of the period of the DRX level.

11 is an example showing a method of receiving data according to another variant implementation of the present invention.

Refer to 11, there are many working levels on depending on the number and levels of acceptance. In 'OPTION 1' has the DRX level and the level of Non-DRX in the absence of level expectations. In 'OPTION 2' has DRX level and the level of Non-DRX in idle. In the level 'OPTION 3' has two levels of DRX and the level of Non-DRX. This document describes three working level, but there may be more than two or four working level.

In 'OPTION 1' ON awakening in the second phase of the period of the first DRX level. In the first subcycle of the second phase of the period of the first DRX level ON confirms the presence of their data with information planning and included in the level of Non-DRX. Accepts data throughout the second phase of the period of the first DRX level in which it awakened. If data is missing in the first subcycle of the third phase of the period of the first DRX level, again enters the DRX level.

In 'OPTION 2' ON awakening in the second phase of the period of the first level, the DRX. In the first subcycle of the second phase of the period of the first DRX level ON confirms the presence of their data with information planning and included in the continuous reception level. When continuous data reception after waking up, if for nothing else planned, it immediately goes into standby mode. If the data is in the first subcycle of the third phase of the period of the first DRX level, again continuously receives the data. If his data were not included in the first subcycle of the third phase of the period of the first DRX level, again enters the DRX level.

In the level 'OPTION 3' awakens in the second phase of the period of the first DRX level. In the first subcycle of the second phase of the period of the first DRX level ON confirms the presence of their data with information planning and included in the continuous reception level. When continuous data reception after waking up, if for nothing else planned, it automatically goes to the second DRX level. Then takes the first subcycle of each period of the second DRX level until the start of the next period of the first DRX level. If scheduled in the first subcycle period of the second DRX level, it awakens and continuously receives data over the entire period of the second DRX level. If his data were not included in the first subcycle of the third phase of the period of the first DRX level, again goes to the first DRX level.

The following describes the method DRX associated with the transfer of upward communication.

Generally, when transmitting data or control message to the BS, the BS immediately transmitted response message. At this point it is advantageous to use the DRX level, with a short period of a DRX level, or the level of Non-DRX.

If FOR transmitting data or control message to the BS, changes IN the level of reception. New reception level may be the level of Non-DRX or a new DRX level. When moving to a new level of acceptance after the transfer for uplink communications, a new level of reception is determined in advance when establishing or restoring the connection. For example, after completing transmission of upward communication in the first DRX level can move to the second DRX level. Alternatively, after the transfer, on an ascending line in the first DRX level can jump in the level of Non-DRX.

When requesting allocation radioresource, it can go on to a level Non-DRX. For example, if the software uses RACH, it goes to the level of Non-DRX after transmission of the preamble. If radioresource data or control message is allocated for channel planning as a response to the RACH, can move to the second DRX level.

Fig is an example that shows how to send e is the R according to a variant implementation of the present invention.

Contact Fig, initially located on the first DRX level. BY transmitting data on DU BS. After the data D1 in the ascending line of communication when working on the first DRX level ON advances to the second DRX level. Alternatively, you may go on to a level Non-DRX and not to the second DRX level, depending on the settings. The time FOR transmitting data in the ascending line, may coincide with the moment of transition to the second DRX level, or the first may precede the latter, or the latter may precede the first.

After the second DRX level BY looking for the first subcycle of each period of the second DRX level and confirms transferred his data from the BS. After the second DRX level, if not accept any data from the downlink during a certain period of time or does not take any information on channel planning, again goes to the first DRX level. If FOR infinitely runs in the second DRX level after transition to the second DRX level after the transmission of upward communication, this can lead to undesirable effects on power consumption. Using the time counter, calculates a certain period of time after dispatch, or a certain period of time may involve a number of periods of the second DRX level, to the torus is located after the transfer. A certain period of time can be set when connecting or reconnecting.

When operating in the second DRX level can again go to the first DRX level at the starting point of the period of the first DRX level. Alternatively, you may use the DRX indicator.
