The technical solution of the present invention will be further described in detail below through the accompanying drawings and embodiments. The core idea of the embodiment of the present invention is that a broadcast message sent by a base station (for example, an eNodeB) through a System Information Block (SIB) indicates to a UE the location of a group paging message to be sent by a base station in an MBSFN subframe. The user equipment is enabled to receive the group paging message on the MBSFN subframe, thereby implementing the group paging message transmission on the MBSFN subframe.

The group paging mechanism based on the eMBMS system and the method for transmitting the group paging message can implement fast group establishment, late entry, and auxiliary group area management; several paging mechanisms are described below, including groups. Content, trigger condition, number of transmissions, operation of the terminal, flow of paging initiation, etc., wherein the group paging message can be used for the initial call and later.

FIG. 1A is a flowchart of a fixed area group paging establishment in which a trigger condition is an initial call. The group paging message may include, but is not limited to: a call type, a group ID, a service ID, and a lecture ID. The main priority, the group uplink status (for example, whether it is idle), the group status (for example, setup/end), and so on. The call type can be a fixed area group call or a shifted area group call.

1. The Mobility Management Entity (MME) initiates a group call to a multicast coordinating entity (MCE);

2. The MCE notifies the corresponding eNB (eNodeB) to initiate a group call in the fixed cell specified by the fixed area;

3. The eNB sends a group paging message (for example, including a call type, a group ID, or a service ID, etc.) on the air interface channel, and simultaneously sends a group service channel indication message and a corresponding group service; The group service may not have arrived yet, but the downlink service pipeline has been established; wherein the small group paging period is T1 and the duration is t1;

4. The UE listens to the group paging message, and determines whether to receive the group service according to the group group paging message.

5. If the UE decides to receive the group service, and listens to the group service channel indication message, where the UE of the radio resource control idle state (RRC_IDLE) may not provide feedback; After the UE listens to the group service channel indication message, it starts to receive the group service. 7. After the eNB times, the eNB stops sending the group page message.

FIG. 1B is a flowchart of an offset area group paging establishment with a trigger condition of an initial call, as shown in the figure:

1. The MME initiates a group call to the MCE.

2. The MCE notifies the corresponding eNB to initiate a group call in the cell involved in the shifted area, including the cell in which the UE of the radio resource control connection state (RRC_CONNECT) is located, and the tracking area of the UE in the RRCJDLE state (tracking area, TA) ) ;

3. The eNB sends a group paging message (including, for example, a call type, a group ID, or a service ID, etc.) on the air interface channel, where the group paging message is sent in a period of T2 and has a duration of t2; The group service indication message and the corresponding service data are not immediately sent, that is, the downlink pipeline is not immediately established;

4. The UE listens to the group paging message, and determines whether to receive the group service according to the group paging message;

5. If the UE decides to receive the group service, the UE must maintain the entire group call process.

In the RRC_CONNECT state, the UE that is in the RRC_IDLE state must provide feedback to let the MME know the cell in which the UE is located;

In the RRCJDLE state, the UE actively enters the RRC_CONNECT state, so that the MME knows which cell it is in. In addition, in the transition area, the UE must maintain the RRC_CONNECT state during the entire group call process, so that the MME can know the cell where the UE is located at any time;

After the continuation of the t2 time, the eNB stops sending the group paging message, and the MME checks the UE with the feedback position and the cell where the UE in the RRC_CONNECT state is located, and updates the shifted area cell range;

7. The MME sends a group service channel indication message to the eNB through the MCE, and the eNB sends a group service indication message on the air interface channel. 8. The MME notifies the enhanced multimedia broadcast/multicast service gateway (eMBMS GW) to deliver the group service;

The eMBMS GW establishes a downlink bearer and delivers the group service to the eNB.

10. The eNB sends a group service on the air interface channel.

11. After the UE listens to the group service channel indication message, the UE starts to receive the group service.

FIG. 2A is a group paging establishment process in a fixed area under the condition that the trigger condition is that the UE starts up later and re-enters the group service coverage cell (it is said to be late).

In this case, the eNB notifies the UE of the existing group service through the group status message, and achieves the purpose of paging, which is also a paging method. The group status message includes call type, group ID, service ID, talker ID, talker priority, or group uplink status (for example, whether it is idle).

The MME can learn the group that the UE subscribes to, and the service information in the group, and the group status message and the group service are sent in the same time period and the same cell range, and the group service that all UEs subscribe to is sent by the network, unless The UE quits the service.

1. After the initial call ends, or after waiting for a period of time t3, the eNB sends a group status message on the air interface channel (for example, including call type, group ID, service ID, talker ID, talker priority, or group). In the uplink state (for example, whether it is idle) or the like, for example, the eNB continuously sends the group status message in the sending period T3 in the cell determined by the group area management; in addition, the eNB sends the group service indication message on the air interface channel. ;

2. The UE listens to the group status message when it is turned on later and re-enters the group service coverage cell; 3. The UE finds a signed group status message, and determines whether to receive the group service;

4. If the UE decides to receive the group service, execute 5;

5. The UE listens to the group traffic channel indication message; then in 6, the UE starts to receive the group service.

The UE that enters late may actively enter the RRC_CONNECT state, and adopt the method shown in FIG. 2B for the UE that can actively enter the RRC_CONNECT state, for the RRC_IDLE state. The UE is processed by the method shown in Fig. 2C.

As shown in FIG. 2B, it is an implementation method for the UE to enter the group paging later, as can be seen from FIG. 2B.

1. The UE sends a Non-Access Stratum (NAS) message to the MME, and enters the RRC-CONNECT state;

2. The MME determines whether the cell in which the UE is located has sent the group channel indication message and the group service. If the group channel indication message and the group service have not been sent, the MME is ready to transmit in the cell.

3. The MME sends a group status message to the eNB in the d and the area where the UE is located, and sends the group status message to the eNB through the MCE, and the eNB sends a group status message on the air interface channel of the cell where the UE is located, where the group status message may be Including call type, group ID, service ID, talker ID, talker priority, or group uplink status (for example, whether it is idle);

The MME sends a service channel indication message to the MCE, and the MCE sends the service channel indication message to the eNB, and then the eNB sends a group service indication message to the UE on the air interface channel of the cell where the UE is located;

5. The MME sends a group service to the gateway GW.

6. The GW establishes a downlink bearer with the eNB and delivers the group service;

7. The eNB sends the group service on the air interface channel of the cell where the UE is located;

8. The UE listens to the group status message sent by the eNB.

9. The UE listens to the group service channel indication message sent by the eNB.

10. The UE starts to receive the group service sent by the eNB.

As shown in FIG. 2C, it is another implementation method for the UE to enter the group paging later. As can be seen from FIG. 2C, the UE in the RRC_IDLE state sends a group status message in its tracking area. The specific steps are as follows:

1. The UE is in the RRC_IDLE state;

2. The MME notifies the MCE that all the cell sending groups in the tracking area of the RRC_IDLE state UE The group status message, the MCE determines whether all cells in the tracking area of the UE have sent a group status message, and if there are cells that have not been sent, are ready to send in the cells;

3. The MCE informs the eNB to send a group status message in the corresponding cell list, and the eNB sends the message on the air interface channel of the corresponding cell, where the group status message may include a call type, a group ID, a service ID, a lecture ID, and a priority. , or group uplink status (for example, whether it is idle), etc.;

4. The UE listens to the group status message.

5. The UE sends a NAS message to the MME, and enters an RRC_CONNECT state.

6. The MME learns that the cell where the UE is located, and prepares to send the group service channel indication message and the group service in the cell where the UE is located;

The MME sends a group service channel indication message to the eNB through the MCE, and the eNB sends a group service channel indication message on the air interface channel of the cell where the UE is located;

8. The MME port eMBMS GW delivers the group service;

The eMBMS GW establishes a downlink multicast bearer and delivers the group service to the eNB.

10. The eNB sends the group service on the air interface channel of the cell where the UE is located;

11. The UE listens to the group service channel indication message;

12. The UE starts to receive the group service.

The embodiment of the present invention can be used in the group paging method of the foregoing paging procedure. In the embodiment of the present invention, the base station and the UE are involved. Of course, the process shown in FIG. 3 is merely an example of a user equipment in a fixed cell connection state. In actual use, a UE that can be changed between a region and an idle state is similar, and is not described in detail.

An embodiment of the present invention provides a group paging method. In this embodiment, the execution entity is a base station. As shown in FIG. 3, the method includes:

Step 301: Send a system information block (SIB) to a user equipment (UE), where the SIB carries resource location information of a group paging message.

Specifically, the base station may specify a sending group paging in the SIB (eg, SIB13) information. The number of the physical multicast channel (PMCH), or the MBSFN subframe that transmits the group paging message by the radio frame offset, the subframe position, and the logical channel identification (logical channel identify, LCID) distinguishes whether it is a paging message.

Step 302: Send a group paging message to the UE in an MBSFN subframe corresponding to the resource location information carried by the SIB.

Specifically, the base station may send a group paging message in a multimedia broadcast multicast service session (mbms-Session) in the PMCH of the sending group paging message carried in the SIB, or The group paging message is sent to the UE in the MBSFN subframe of the transmission group paging message specified by the radio frame offset and the subframe position.

With the above embodiment, the base station can send a group paging message in an MBSFN subframe, for example, periodically send a group paging message according to a specified PMCH and mbms-Session, or according to a specified radio frame offset, and a sub- The frame position periodically sends a group page message.

In an implementation manner of the embodiment of the present invention, the base station may carry the group paging message in an mbms-Session in the MBSFN subframe, and broadcast the PMCH of the mbms-Session where the group paging message is located in the SIB. And the LCID, where the sending period of the group paging message (hereinafter referred to as a paging period) is related to the scheduling period of the PMCH in which it is located, and the paging period indication information may also be broadcasted in the SIB.

The resource location information in the SIB indicates which MMms-Session of the PMCHs carry the group paging message. At this time, the resource location information includes a PMCH number, and an LCID of the mbms-Session.

In this way, the base station can determine the PMCH corresponding to the PMCH number by using the resource location information carried in the SIB, where the PMCH is located in the MBSFN subframe; and determine the corresponding mbms-Session by using the LCID. Referring to FIG. 4, at this time, the above step 302 includes:

Step 401: Determine a PMCH corresponding to the PMCH number, where the PMCH is located in the MBSFN subframe. Step 402: Determine an mbms-Session corresponding to the LCID in the determined PMCH. Step 403: Send a group paging message to the UE in the determined mbms-Session. For example, in each PMCH, the mbms-Session with the logical channel number LCID of 1 is dedicated to sending the group paging message. Of course, here is only an example, other PMCH or mbms-Session may also be agreed. For example, the base station may also The embodiment of the present invention does not impose any limitation on the PMCH whose number is even or odd.

The MBSFN-AreaInfo-r9 is a description of the MBSFN area configuration information in the Long Term Evolution (LTE) radio resource control protocol, where the information about the multicast control channel (MCCH) in the MBSFN area is defined. , broadcast in system message SIB13. Therefore, the above method can be implemented by adding a pagingPMCH and a paging-mbms-Session-LCID in the above information, where the pagingPMCH indicates the PMCH number in the radio frame where the group paging message is located, and the PMCH is carried on the MBSFN subframe. The physical multicast channel, paging-mbms-Session-LCID, represents the logical channel number of the mbms-Session where the group paging message is located.

The pagingPMCH indicates the number of the PMCH that the base station sends the group paging message, which may be each

PMCH, or PMCH numbered even or odd. The embodiment of the invention does not impose any limitation.

In addition, the base station may also be configured with the UE to send the PMCH number of the group paging message, for example, in the mbms-SessionO of each scheduling period of the PMCH0. Here, for example, other PMCH or mbms-Session may also be agreed. The embodiment of the invention does not impose any limitation.

In addition, the SIB may further include paging period indication information, where the paging period indication information may be, for example, pagingMCHCoeff, and pagingMCHCoeff indicates a multiple relationship between a paging period and a multicast channel (MCH) scheduling period, for example, pagingMCHCoeff It can be 1, 2, 3 or 4, etc., and the paging message is 1, 2, 3 or 4 times of the MCH scheduling period. Of course, these multiples are only examples, and are not intended to limit the embodiment. In a specific implementation, those skilled in the art may set the multiple according to actual needs. The base station may determine a specific mbms-Session for carrying the group paging message according to the LCID indicated by the paging-mbms-Session-LCID in the parameter, and the base station may also agree with the UE to set the group paging message by directly specifying the manner. The transmission period and the mbms-Session logical channel number or number.

For example, in MBSFN-AreaInfo-r9, add the port-mbms-Session-index to indicate the number of mbms-Session.

For another example, the group paging message is sent on each mbms-Session with an LCID of 1 in each scheduling period of each PMCH, or is specified on each mbms-SessionO in each scheduling period of each PMCH, and then Or, in each scheduling period of the PMCH0, the mbms-SessionO is sent, and the other PMCH or mbms-Session may be stipulated in the embodiment of the present invention.

In the received SIB, the UE reads the parameters pagingPMCH and paging-mbms-Session-LCID, determines the mbms-Session that sent the group paging message, and then reads the MCCH from the corresponding location to obtain the PMCH configuration information, and finally configures Information, read the above mbms-Session. In addition, the paging period indication information, such as pagingMCHCoeff, may also be included in the SIB. In this manner, the UE may read the paging period indication information to determine a transmission period of the group paging message. In addition, the SIB may also include multicast control channel (MCCH) location information or modulation and coding mode indication information, so that the UE can learn the MCCH location information or the modulation coding scheme (MCS) to find the group paging. The location of the message, and decode the group page message.

In general, in this embodiment, the resource location information in the SIB includes a physical multicast channel PMCH number for carrying the group paging message, and a logical channel number LCID of the mbms-Session; One or more of the following information is included: paging cycle indication information, MCCH location information, and modulation coding mode indication information.

The base station is in the physical multicast channel PMCH corresponding to the resource location information carried by the SIB. In the mbms-Session, a group paging message is sent to the UE.

In another implementation manner, the base station broadcasts the subframe position of the group paging message in the SIB, and the subframes serve as the multiplex subframe, and simultaneously carry the multicast traffic channel (MTCH) and the multicast homing. The content of the Multicast Paging Chanel (MPCH) is differentiated according to the logical channel number, and is used to carry the logical channel of the group paging message, that is, the MPCH.

Specifically, the base station broadcasts the resource location information of the group paging message in the SIB, including but not limited to the following information: a radio frame offset location, a subframe location, and a logical channel number LCID carrying the group paging message.

The paging-Offset parameter determines a radio frame offset position sent by the group paging message, that is, which specific radio frame in each radio frame period transmits the group paging message.

The paging-sf-AllocInfo parameter determines the MBSFN subframe position sent by the group paging message. For example, it may be a bit-map of length 6. That is, in 10 subframes of one radio frame, up to 6 in FDD. The MBSFN subframe configured to send the group paging message; under TDD, up to 5 subframes can be configured to send the group paging message MBSFN subframe. In this case, only the first 5 bits of the 6 bits are used, and the Uplink subframe. In frequency-division duplex (FDD), these 6 bits represent subframes 1, 2, 3, 6, 7, and 8, in time-division duplex (TDD), the first 5 bits. The bits in turn represent subframes 3, 4, 7, 8, 9. The T indicates that the group paging message can be sent in the MBSFN subframe, and the "0" indicates that the group paging message is not sent in the MBSFN subframe. Of course, this embodiment does not impose any restrictions. It can also use "0" to indicate that the MBSFN subframe sends a group paging message, and "1" to indicate that the group paging message is not sent in the MBSFN subframe. 5A is a schematic diagram of a subframe that can be configured as an MBSFN subframe in an FDD mode. It can be seen that 1, 2, 3, 6, 7, and 8 can all be configured as MBSFN subframes, so 1, 2, 3, 6, and 7. Each of the 8 subframes may be configured as a subframe in which the base station transmits a group paging message.

FIG. 5B is a schematic diagram of a subframe that can be configured as an MBSFN subframe in a TDD mode. According to different uplink and downlink ratios, an MBSFN subframe may be configured as a downlink subframe, and only subframes 3 and 4 may be configured. 7, 8, 9, therefore, the MBSFN subframes that can be sent by the base station to the group paging message can only be subframes 3, 4, 7, 8, 9, at this time, the last bit in the paging-sf-AllocInfo parameter The bit is invalid.

In addition, the above resource location information may further include a paging cycle, and a sending period of the group paging message is determined, for example, paging-RepetitionPeriod.

In this embodiment, the medium access control (MAC) multiplexing mode is adopted, that is, the MBSFN subframe in the physical layer carries the service information of different logical channels at the same time, and therefore needs to be determined according to the LCID. A logical channel used to carry group paging messages. Then, the logical channel used to carry the group paging message can be specified by parameters in the SIB, or the way the base station directly agrees with the terminal.

If the logical channel used to carry the group paging message is specified by the parameter in the SIB, the LCID parameter field needs to be set in the SIB; and if in the agreed manner, the base station sends the group according to the specified MBSFN subframe configuration. For paging messages, the LCID can be directly specified as 1. If the MPCH occupies the LCID number 1, the MTCH in the same PMCH can no longer occupy the LCID number 1. If a group page occurs, the MTCH does not occupy the mbms-Session with the LCID number of 1. When there is no group page. The mbms-Session in the MTCH can occupy the LCID number 1.

In order to avoid the difference between the MCS selection and the MCS on the original subframe, it is contradictory to the original eMBMS. When the base station encodes the group paging message, the MCS of the paging message is selected to use the MCS coding of the same MCCH when the MPCH and the MCCH are in the same subframe (that is, the same subframe is multiplexed); when the MPCH and the MCCH are not in use When the same subframe (that is, the same subframe is not multiplexed), the MCS encoding of the PMCH corresponding to the multicast channel MCH of the MPCH is used. If the MPCH and MCH scheduling information (MSI) are in the same subframe, the MCS coding of the MCCH is adopted. The priority sequence sent by the base station is that the priority of the MPCH is specified to be smaller than the MCCH and greater than the MTCH; that is, when the MTCH, MPCH, and MCCH data are simultaneously present, the base station first transmits the MCCH, then the MPCH, and finally the MTCH. In implementation, the paging-RepetitionPeriod, paging-Offset, and paging-sf-AllocInfo parameters can be added to the MBSFN-AreaInfo-r9 and carried in the SIB.

In general, in this implementation manner, the resource location information sent by the base station by using the SIB specifically includes a radio frame offset position, a subframe position, and a logic for carrying a group paging message, where the base station sends the group paging message. Channel number LCID. Referring to FIG. 6 , the foregoing step 302 includes: Step 601: The base station determines a radio frame corresponding to the radio frame offset position, for example, the base station determines, by using a paging-Offset, a radio frame corresponding to the radio frame offset position;

Step 602: The base station determines, in the determined radio frame, the MBSFN subframe corresponding to the subframe position, for example, the base station determines, by using paging-sf-AllocInf, the sub-frame in the radio frame determined by the paging-Offset The MBSFN subframe corresponding to the frame position;

Step 603: Determine, in the determined MBSFN subframe, a logical channel corresponding to the LCID. Step 604: Send a group paging message to the UE on the determined logical channel.

The resource location information sent by the base station through the SIB may further include a paging cycle in which the base station transmits the group paging message, for example, paging-RepetitionPeriod. At this time, in the above step S640, the group paging message is transmitted to the UE on the determined logical channel according to the paging cycle determined by the paging-RepetitionPeriod.

FIG. 7 is a flowchart of another embodiment of a group paging method according to an embodiment of the present invention. In this embodiment, an execution entity is a UE, as shown in FIG. 7, the method includes Step 701: Receive a system information block (SIB) sent by a base station, where the SIB carries resource location information of a group paging message.

Specifically, the UE may receive the SIB through a Broadcast Control Channel (BCCH), and carry the resource location information of the group paging message sent by the base station in the SIB.

Step 702: Acquire, according to the SIB, resource location information of the group paging message. Specifically, after receiving the SIB, the UE reads the resource location information, and determines, according to the resource location information, the carrying group paging message. Resource location. For example, if the base station sends the physical multicast channel PMCH number of the group paging message and the logical channel number LCID of the mbms-Session in the SIB, the UE acquires the group paging message. The PMCH number in the MBSFN subframe.

If the base station sends the radio frame offset position, the subframe position, and the logical channel number of the group paging message sent by the base station in the SIB, the UE acquires the specific MBSFN subframe that carries the group paging message. The location, such as the number of MBSFN subframes, and on which logical channel the group page message is obtained.

Step 703: Acquire, according to the resource location information, a group paging message in an MBSFN subframe corresponding to the resource location information.

Corresponding to the case where the resource location information includes the PMCH number and the LCID of the mbms-Session,

The UE acquiring the group paging message according to the resource location information may include the steps shown in FIG. 8:

Step 801: Determine a PMCH corresponding to the PMCH number, where the PMCH is located in the MBSFN subframe.

Step 802: Determine an mbms-Session corresponding to the LCID in the determined PMCH. Step 803: Acquire, in the determined mbms-Session, the group paging message.

After acquiring the group paging message, the UE may also decode the group paging message, and the encoding mode of the group paging message needs to be known for correct decoding. Therefore, the resource location information may further include modulation and coding mode indication information, so that the UE can read the modulation and coding mode indication information, and perform decoding according to the MCS indicated by the modulation and coding mode indication information.

In addition, the resource location information may further include paging cycle indication information, so that the UE can learn the transmission period of the group paging message, thereby correctly finding the location of the group paging message.

Furthermore, the resource location information may further include a multicast control channel MCCH location information, the UE reads the MCCH location information, then reads the MCCH from the corresponding location, obtains the PMCH configuration information, and finally reads the mbms-Session through the configuration information.

Corresponding to resource location information including a radio frame offset location, a subframe location, and for carrying the group In the case of the LCID of the logical channel of the group paging message, the UE acquiring the group paging message according to the resource location information may include the steps shown in FIG. 9:

Step 901: Determine a radio frame corresponding to the radio frame offset position.

Step 902: Determine, in the determined radio frame, the MBSFN subframe corresponding to the subframe position.

Step 903: Determine, in the determined MBSFN subframe, a logical channel corresponding to the LCID. Step 904: Obtain a group paging message in the determined logical channel.

After acquiring the group paging message, the UE may also decode the group paging message, and the encoding mode of the group paging message needs to be known for correct decoding.

For example, the decoding mode may be based on whether the MPCH of the specific bearer group paging message is

The MCCH is the same to determine. If the subframe that specifically carries the group paging message is in the same subframe as the MPCH and the MCCH (that is, the same subframe is multiplexed), the decoding mode is the same as the MCS of the MCCH; otherwise, if the subframe that specifically carries the group paging message is used as the subframe When the MPCH and the MCCH are not in the same subframe (that is, the same subframe is not multiplexed), the decoding mode is the same as the MCS of the PMCH corresponding to the MCH carrying the MPCH.

For example, if the MPCH and MCH scheduling information (MSI) are in the same subframe (that is, the same subframe is multiplexed), the decoding mode is the same as the MCS of the MCCH; otherwise, the decoding mode corresponds to the MCH of the MPCH carrying the MPCH. The PMCH of the PMCH is the same. That is, if one or all of the MCCH and the MSI are multiplexed with the same subframe as the MPCH for the 7_group group paging message, the group paging is performed by using a decoding mode corresponding to the MCCH modulation and coding scheme. The message is decoded. If the MCCH and the MSI are not multiplexed with the same subframe as the MPCH for the group paging message, the group paging message is adopted by using the modulation coding mode of the PMCH corresponding to the MCH of the MPCH. Decode.

With the foregoing embodiment, the UE receives the group paging message on the MBSFN subframe, and then can receive the service data immediately, without causing additional delay, and saving eMBMS air interface resource waste. In addition, the group paging message only occupies the air interface resources of the eMBMS service, and does not have a performance impact on the non-eMBMS service. The resource scheduling algorithm does not need further design, and the development and maintenance costs are reduced compared with the prior art.

In the embodiment shown in FIG. 7, the manner in which the UE acquires the location of the resource carrying the group paging message is different, because the content carried by the resource location information carried by the base station is different.

In one embodiment, the UE reads a broadcast message (e.g., SIB), obtains a group paging message location, or directly specifies a paging message location.

The UE reads the resource location information in the SIB, and acquires which mbms-Session of the PMCHs to carry the group paging message. For example, in each PMCH, the mbms-Session with an LCID of 1 is dedicated to sending a group paging message, and the transmission period is the pagingMCHCoeff times of the MCH scheduling period. It can also be sent only in the PMCH whose number is even or odd.

MBSFN-AreaInfo-r9 defines the information about the MCCH and multicast control channel in the MBSFN area, which is broadcast in the system message SIB 13.

The base station adds parameters such as pagingPMCH and paging-mbms-Session-LCID in MBSFN-AreaInfo-r9, where pagingPMCH indicates the PMCH number in the radio frame where the group paging message is located, and paging-mbms-Session-LCID indicates the group search. The logical channel number of the mbms-Session where the message is located, pagingMCHCoeff determines that the paging cycle is a multiple of the MCH scheduling period.

The number of the mbms-Session may also be directly specified according to the agreement with the base station, for example, it is specified to be received on the mbms-Session with the LCID of 1 in each scheduling period of each PMCH, or each scheduling in each PMCH. In the cycle, mbms-SessionO is received, or is received on mbms-SessionO in each scheduling cycle of PMCH0.

In addition, the UE may also agree with the base station to transmit the PMCH number of the group paging message, for example, in the mbms-SessionO of each scheduling period of the PMCH0.

After that, the UE reads the mbms-Session through the original eMBMS mechanism to obtain a specific group. Group paging message.

In the SIB, the UE reads the previously read parameters pagingPMCH, paging-mbms-Session-LCID to specify the mbms-Session to which the group paging message is sent.

The UE determines the PMCH number in the MBSFN that receives the group paging message through the pagingPMCH, determines the paging cycle through the pagingMCHCoeff, and determines the mbms-Session of the group paging message through the paging-mbms-Session-LCID.

Simultaneously listen to the broadcast message SIB, read the MCCH location information and MCS, then read the MCCH from the corresponding location, obtain the PMCH configuration information, and finally read the above mbms-Session through the configuration information.

In summary, the UE acquires, according to the SIB, a physical multicast channel PMCH number, a logical channel number LCID of the mbms-Session, and a sending period indication information of the group paging message.

The UE obtains the group paging message according to the sending period of the group paging message in the mbms-Session of the PMCH corresponding to the PMCH, and the mbms-Session corresponds to the LCID information.

In another embodiment, the group page message is sent in a designated MBSFN subframe configuration.

Since the base station broadcasts the resource location information of the group paging message in the SIB, including but not limited to the following information,

1) paging-RepetitionPeriod, the radio frame period of the group paging message, that is, the paging period, the group paging message is sent in the radio frame satisfying the following relationship: SFN mod paging-RepetitionPeriod = 0;

2) paging-Offset, the radio frame offset position sent by the group paging message, satisfying SFN mod paging-RepetitionPeriod = paging-Offset;

3) paging-sf-AllocInfo, the subframe position sent by the group paging message, is 6 in length Bit-map, for example, T means for group paging message transmission;

4) LCID can be directly specified as 1.

Determining, by the UE, a radio frame used to send the group paging message according to the paging period paging-RepetitionPeriod and the radio frame offset position paging-Offset;

Determining, according to the subframe position, paging-sf-AllocInfo, a location of the MBSFN subframe; determining, according to the LCID, a logical channel that carries the group paging message;

Then, in the logical channel, a group paging message is obtained.

If the subframe corresponding to the obtained resource location, that is, the MPCH and the MCCH are in the same subframe, after receiving the SIB carrying the above parameters, the UE uses the same MCS as the MCCH for decoding, if the MPCH and the MSI are in the same sub- The frame also uses the MCS of the MCCH. Otherwise, it is decoded by the same decoding method as the MCS of the PMCH corresponding to the MCH of the MPCH. After the decoding, the service data unit (SDU) corresponding to the same logical number as the LCID, when there is no corresponding LCID field in the MSI, the SDU is the bearer of the group paging message. SDU.

In summary, the UE acquires, according to the SIB, a base station to send the group paging message radio frame offset position, a subframe position, and a logical channel number LCID of the mbms-Session. The UE acquires a group paging message according to the obtained location information.
