Description

Method for the network side to know the situation of users receiving multimedia broadcast/multicast services

technical field

The invention relates to the realization technology of multimedia broadcast/multicast service (MBMS), in particular to a method for the network side to know the situation of users receiving the MBMS service.

Background technique

Multicasting and broadcasting are techniques for delivering data from one source to multiple destinations. In traditional mobile networks, Cell Broadcast Service (CBS: Cell Broadcast Service) allows low bit rate data to be sent to all users through the shared broadcast channel of the cell, which belongs to the message service.

Now, people's demand for mobile communication is no longer satisfied with telephone and message services. With the rapid development of the Internet, a large number of multimedia services have emerged, some of which require multiple users to receive the same data at the same time, such as video on demand, TV, etc. Broadcasting, video conferencing, online education, interactive games, etc. Compared with general data, these mobile multimedia services have the characteristics of large data volume, long duration, and delay sensitivity. The current IP multicast technology is only applicable to wired IP networks, but not to mobile networks, because mobile networks have specific network structures, functional entities and wireless interfaces, which are different from wired IP networks.

In order to effectively utilize mobile network resources, WCDMA/GSM global standardization organization 3GPP proposed multicast and broadcast services (MBMS: Multimedia Broadcast/Multicast Service), which provides a data source in a mobile network to send data to multiple users. point services, realize network resource sharing, and improve the utilization rate of network resources, especially the utilization rate of air interface resources. The MBMS defined by 3GPP can not only realize plain text and low-rate message multicast and broadcast, but also realize multicast and broadcast of high-speed multimedia services, which undoubtedly conforms to the trend of future mobile data development.

In order to support MBMS services, a new mobile network functional entity—broadcast and multicast service center BM-SC is added to the mobile network. Time plan for delivery of MBMS content. In addition, functional entities such as user equipment (UE), terrestrial radio access network (UTRAN), GERAN, SGSN, and GGSN are enhanced, adding MBMS-related functions.

Refer to FIG. 1 for such a network structure, which is a schematic structural diagram of a wireless network supporting multicast/broadcast services. Among them, the Broadcast/Multicast Service Center (BM-SC) is connected to the Gateway General Packet Radio Service (GPRS) Support Node (GGSN, Gateway GPRS SupportNode) through the Gmb interface or the Gi interface, and one BM-SC can be connected to multiple GGSNs; The GGSN is connected to the Serving GPRS Support Node (SGSN, Serving GPRS Support Node) through the Gn/Gp interface, and one GGSN can be connected to multiple SGSNs; the SGSN can be connected to the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN) through the Iu interface ), then the UTRAN is connected to the communication terminal through the Uu interface, and the SGSN can also be connected to the Global System for Mobile Communications (GSM) Enhanced Radio Access Network (GERAN) through the Iu/Gb interface, and then GERAN is connected to the communication terminal through the Um interface.

MBMS includes multicast mode and broadcast mode. The difference between the multicast service and the broadcast service is only that: the multicast service only sends corresponding information to users who have subscribed to certain information, while the broadcast service sends information to all users in the wireless network. The multicast mode requires the user to sign up for the corresponding multicast group, activate the service, and generate corresponding billing information. Since the multicast and broadcast modes have different business requirements, their business processes are also different.

Refer to Figure 2 for the complete flow of a user receiving an MBMS broadcast service. As shown in Figure 2, the flow includes: Service announcement, Session Start, MBMS notification, Data transfer ), session end (Session Stop) process.

Among them, the Service announcement process is used for the BM-SC to announce the services that can be provided currently.

During the Session Start process, the BM-SC is ready for data transmission and notifies the network to establish the bearer resources of the corresponding core network (CN) and universal terrestrial radio access network (UTRAN).

The MBMS notification process is used to notify the UE that the MBMS multicast session is about to start.

During the data transfer process, the BM-SC transmits data to the UE through the bearer resources established during the session start process.

The Session Stop process is used to release the bearer resources established by the Session Start process.

In the broadcast service, each MBMS service node stores the bearer context of the MBMS service, and the bearer context is activated during the Session Start process and deactivated during the Session Stop process.

Refer to Figure 3 for the complete flow of a user receiving an MBMS multicast service. As shown in Figure 3, the flow includes: Subscription, Service announcement, Joining, Session Start, MBMS Notification (MBMS notification), data transfer (Data transfer), session end (Session Stop) and leaving (Leaving) process.

Wherein, the Subscription process is used to allow the user to pre-subscribe the desired MBMS service.

The Service announcement process is used by the BM-SC to announce the currently available services.

The Joining process is the MBMS multicast service activation process. During the Joining process, the UE notifies the network that it is willing to become a member of the current multicast group and receive the multicast data of the corresponding service. Create MBMS UE context for recording UE information.

During the Session Start process, the BM-SC is ready for data transmission and notifies the network to establish the bearer resources of the corresponding CN and UTRAN.

The MBMS notification process is used to notify the UE that the MBMS multicast session is about to start.

During the data transfer process, the BM-SC transmits data to the UE through the bearer resources established during the session start process.

The Session Stop process is used to release the bearer resources established by the Session Start process.

The Leaving process causes subscribers in the group to leave the multicast group, that is, the user no longer receives multicast data, and this process will delete the corresponding MBMS UE context.

There are two service bearer modes when the MBMS service is transmitted between UTRAN and UE: point-to-multipoint (PTM) mode and point-to-point (PTP) mode. The PTM mode sends the same data through the MBMS point-to-multipoint service channel (MTCH), and all UEs that join the multicast service or are interested in the broadcast service can receive it; the PTP mode sends data through the dedicated transport channel (DTCH), and only the corresponding One UE can receive.

An important factor for determining whether the MBMS service adopts PTP or PTM bearer mode is: the number of users receiving the MBMS service obtained by the RNC through statistics in the cell. In the RNC, there is a record MBMS service context (MBMS Service Context) for each MBMS service, which includes user records in the RRC Connected and PMM-Connected states. The process of counting the number of users receiving the MBMS service is a Counting process. Specifically, the RNC sends a Counting notification message to the UE, and the UE that joins the service returns a Counting response message to the RNC, and the RNC returns a Counting response message for receiving the service It is recorded in MBMS ServiceContext, and the users receiving the MBMS service in the cell are obtained by counting the number of users in MBMS Service Context. If the number of users is greater than a predetermined threshold, the PTM bearer mode will be used, that is, public channel transmission will be used; otherwise, the PTP mode will be used to establish a dedicated channel for each user to transmit MBMS services.

The RNC not only performs the Counting process before the MBMS service transmission, counts the users who will receive the MBMS service, and determines the bearer mode of the MBMS service to be sent according to the number, but also performs Counting during the MBMS service transmission process, and counts the users who are receiving the MBMS service The users of the MBMS service determine whether to change the bearer mode according to the number.

In fact, the number of services that the UE can join at the same time can be relatively large, but the services that can be received at the same time are very limited. For some low-capability UEs, it can basically be said that only one MBMS service can be received at the same time.

At present, if the UE chooses between two MBMS services provided at the same time, and one of the services uses the point-to-point bearer mode, since there is a dedicated link between the UE and the network side, the UE can easily send the relevant information to the network side. Service information, the network side can have a clear understanding of the user's situation. Specifically, the UE sends the UE's related request to the network side through the RRC message MBMS MODIFICATION REQUEST, and requests the network side to take certain measures to improve the UE's ability to receive MBMS services or sessions (session) preferentially. For UTRAN Generally speaking, the MBMS service is embodied in the form of multiple sessions. If the UE is in the CELL-DCH state, it can decide whether to feed back to the network side whether to establish/reserve/tear down this dedicated connection according to the priority level of the service.

However, if several services simultaneously provided by the network side use point-to-multipoint connections:

Since UEs in Idle, URA-PCH and CELL-PCH states cannot use the uplink channel, they cannot get in touch with the network side at this time. Their own conditions and business-related information include: UE receiving MBMS service priority, UE The ability to receive MBMS services, the MBMS services that UE is receiving, the MBMS services that UE is about to receive, etc., cannot be transmitted to the network. It can be seen that what services UEs in these states are receiving, what their capabilities are, etc. The network side has no idea at this time, so since the network side does not know how many UEs currently joining a certain service can receive the service, it can only It is to count all these users, so that it is actually the default that all users are users with superpowers. The result will naturally be an error in counting the number of users receiving a certain business.

The purpose of choosing the bearer mode is to better save wireless resources, but choosing the wrong bearer mode, in other words, changing the point-to-point bearer mode to point-to-multipoint will cause more waste of power resources, and the counting process is very important for the network Said that the role played will be greatly reduced.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a method for the network side to know the situation of the user receiving the MBMS service, and the application of this method enables the network side to determine the MBMS service bearing mode according to the situation of the user receiving the MBMS service, reducing the waste of power resources .

In order to achieve the above object, the technical solution of the present invention is specifically realized in the following way:

A kind of method that network side learns the situation that user receives multimedia broadcast/multicast service MBMS, this method comprises the following steps:

A. The UE receives the service control information about to or is transmitting the MBMS service sent by the network side;

B. The UE reports its own service reception information to the network side through uplink resources according to the received service control information and/or its own current working condition.

The service reception status information may include: the receiving MBMS service priority table preset by the user and stored in the UE, the UE's ability to receive MBMS services, the MBMS services that the UE is receiving, the MBMS services that the UE is about to receive, whether the user refuses One or more MBMS services, information on one of them or information on the reception status of multiple MBMS services in any combination; or/and reception status information on non-MBMS services.

The service control information described in step A may be: the control information of the MBMS service that the network side sends to the UE through the public control channel to notify that it will or is being transmitted in a point-to-multipoint PTM mode;

The step B is:

After receiving the above control information, the UE directly reports its service reception information to the network side through uplink resources;

Or, after receiving the above control information, the UE judges whether it is currently receiving another or more MBMS services and/or non-MBMS services; if so, reports its own service reception information to the network side through uplink resources.

If the service reception situation information includes the receiving MBMS service priority table, when the UE determines that it is currently receiving another or more MBMS services, it further determines whether the priority of the service indicated in the control information is higher than that of the currently receiving MBMS service. The priority of the service, if yes, prepare to receive the high-priority service in the control information; otherwise, continue to receive the service being received.

When it is determined that the priority of the service indicated in the control information is higher than the priority of the service currently being received, it can be further determined whether the service indicated in the control information is a retransmission service and the UE has correctly received the service, and if so, then Continue to receive the service being received; otherwise prepare to receive the service indicated in the control information.

The step B may further include: if the control information includes frequency layer aggregation information, and the service indicated in the control information has a higher priority than the service being received, perform frequency layer aggregation and prepare to receive the service indicated in the control information; Otherwise, no frequency layer convergence is performed, and the service being received continues to be received.

When the service reception status information includes service capabilities, the UE can further judge whether it can receive the services indicated in the control information according to its own service capabilities, and if so, prepare to receive the services; otherwise, report the MBMS service status information to the network side .

When the UE determines that it is receiving non-MBMS services and receives one or more types of MBMS services, the user needs to decide whether to switch to receive MBMS services or to receive two types of services at the same time. If the user chooses to only receive MBMS services, the UE Notify the network to cut off the existing non-MBMS services; if the user chooses to receive only non-MBMS services or receive two types of services at the same time, continue to receive non-MBMS services.

The method for the user to decide whether to switch to receive MBMS or to receive two types of services at the same time can be:

The non-access stratum of the UE is determined according to the service selection information preset by the user;

Or the non-access stratum of the UE interacts with the user to obtain the user's decision whether to switch to receive MBMS or receive two types of service information at the same time.

The service control information described in step A may be: the notification information sent by the network side to the UE through the common control channel to notify that a kind of MBMS service will be counted;

The step B is:

After receiving the above notification information, the UE directly reports its own MBMS service reception information to the network side through the uplink resources along with the Counting response information;

Or after the UE receives the above notification information, it judges whether it is currently receiving another or more MBMS services; if it is, then reports its own MBMS service reception information to the network side through the uplink resources along with the Counting response information; otherwise, only the The Counting response information is returned to the network side.

When judging that it is currently receiving another MBMS service or non-MBMS service, it can further judge whether to respond to the Counting notification information according to the receiving situation of its own MBMS service or non-MBMS service.

If the MBMS service reception status information includes the receiving MBMS service priority table, when the UE determines that it is currently receiving another MBMS service, it further determines whether the priority of the service indicated in the Counting notification information is higher than that of the currently receiving service If it is the priority, it will respond to the Counting notification message; otherwise, it will not respond to the Counting notification message.

When it is determined that the priority of the service indicated in the Counting notification information is higher than the priority of the service currently being received, further determine whether the service indicated in the Counting notification information is a retransmission service and the UE has correctly received the service information, if yes , the Counting notification message will not be responded; otherwise, the Counting notification message will be responded.

The step B may further include: if the notification information contains frequency layer aggregation information, and the priority of the service indicated in the notification information is higher than the service being received, then perform frequency layer aggregation and respond to the Counting notification information; otherwise, do not perform frequency layer aggregation. Layer aggregation does not respond to Counting notification information.

When the MBMS service reception status information includes service capabilities, the UE can further judge whether it can receive the services indicated in the notification information according to its own service capabilities, and if so, respond to the Counting notification information; otherwise, it does not respond to the Counting notification information.

The step B may further include: after the UE reports its own service reception information, record that it has been reported;

When the UE receives the service control information, it judges whether the MBMS service reception status information has been reported, and if yes, it does not report it; otherwise, it reports it.

If the UE has reported MBMS service reception status information, it further judges whether the MBMS service reception status has changed, and if so, reports it; otherwise, does not report it.

The uplink resource may be: an uplink resource established by the UE or a radio resource specially established for reporting MBMS service reception status information.

The uplink resource established by the UE is: the uplink resource established by the UE for receiving the MBMS service in the current point-to-point PTP mode.

The method for reporting through wireless resources specially established for reporting MBMS service reception conditions may be:

For a UE in the Idle state, it first establishes an RRC connection with the network side, and reports its service reception information to the network side through the established RRC connection;

For the UE in the URA-PCH state, it will transfer to the CELL-FACH state, and use the uplink channel to report its service reception information to the network side;

For the UE in the CELL-PCH state, it will transfer to the CELL-FACH state, and use the uplink channel to report its service reception information to the network side;

For the UE in the CELL-FACH state, it directly uses the uplink channel to report its service reception information to the network side.

In the step B: the UE may regularly report its own MBMS service reception status information to the network side through uplink resources.

When the UE learns that the service reception status information of its own has changed, it can report the information to the network side immediately.

It can be seen from the above-mentioned technical solutions that in the method for the network side of the present invention to know the situation of the user receiving the MBMS service, the UE, after receiving the service control information of the MBMS service to be transmitted sent by the network side, according to the received service control information and its own current For the working status, report the reception status information of its own MBMS service to the network side through the uplink resources. In this way, the network side can accurately count the users receiving the MBMS service in the cell according to the service reception status information reported by each UE, so as to correctly determine the bearer mode and reduce waste of power resources.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and two preferred embodiments.

In the method for the network side of the present invention to know the situation of the user receiving the MBMS service, the UE receives the service control information of the MBMS service that is about to be or is being transmitted from the network side, and then according to the received service control information and/or its current working situation , and report the service reception status information of itself to the network side through the uplink resource.

The service receiving situation information in the present invention may include: the receiving MBMS service priority table preset by the user and stored in the UE, the UE's ability to receive MBMS services, the MBMS services that the UE is receiving, the MBMS services that the UE is about to receive, the user's Whether to reject one or more MBMS services, one of them or arbitrarily combined multiple MBMS service reception status information; or/and non-MBMS service reception status information.

Two preferred embodiments are described respectively below.

First preferred embodiment:

Referring to FIG. 4, FIG. 4 is a processing flowchart of the first preferred embodiment of the method of the present invention. In this embodiment, the MBMS service reception status information to be reported by the UE includes at least: the receiving MBMS service priority table, and the UE's ability to receive the MBMS service. The process includes the following steps:

In step 401, the UE receives control information for providing an MBMS service in a PTM manner, which is sent by the network side through a common control channel.

In step 402, the UE judges whether it is receiving another or more MBMS services or non-MBMS services, and if yes, executes step 403; otherwise, executes step 408.

In step 403, the UE judges whether its capability can receive the MBMS service at the same time, and if yes, executes step 404; otherwise, executes step 405.

Step 404, continue to execute the MBMS service or non-MBMS service being received and the MBMS service in the control information, and end this process.

Step 405, if the user is receiving one or more MBMS services, then judge whether the priority of the MBMS service indicated in the control information is higher than the priority of the MBMS service being received, if yes, then execute step 406; otherwise, execute Step 409.

If the services currently received by the user do not include MBMS services but other non-MBMS services, the user needs to decide whether to switch to receive MBMS services or to receive both types of services at the same time. If the user chooses to only receive MBMS services, the UE will notify the network Disconnect existing non-MBMS services; execute step 406; if the user chooses to receive only non-MBMS services, execute step 409; if the user chooses to receive two types of services simultaneously, execute step 406.

Among them, there are two methods for the user to decide whether to switch to receive MBMS or to receive two types of services at the same time:

The first type: The non-access stratum of the UE decides according to the service selection information preset by the user: if the user sets the priority of the non-MBMS service lower than the MBMS service, choose to receive the MBMS service; if the UE capability allows, choose to receive it at the same time; if The priority of the non-MBMS service is higher than that of the MBMS service, and the capability of the UE does not allow it, so choose not to receive the MBMS service. Of course, if the capability of the UE is high, you can also choose to receive it at the same time.

The second type: the non-access stratum of the UE interacts with the user to obtain the user's decision whether to receive MBMS or to receive two types of service information at the same time.

In step 406, the UE prepares to receive the MBMS service indicated in the control information. This process is the same as that of the prior art, and will not be repeated here.

In step 407, the UE reports to the network side the MBMS service reception status information including the receiving MBMS service priority list and the UE's ability to receive the MBMS service.

If the service being received by the UE is transmitted in the PTP mode, the UE reports the MBMS service reception status information to the network side directly through the uplink radio resource of the dedicated link established by the service.

If the service that the UE is receiving is also transmitted in PTM mode, the UE in different states has different processing, as follows:

For the UE in the Idle state, it first establishes an RRC connection with the network side, and reports its own MBMS service reception information to the network side through the established RRC connection;

For the UE in the URA-PCH state, it will transfer to the CELL-FACH state, and use the uplink channel to report its own MBMS service reception information to the network side;

For the UE in the CELL-PCH state, it will transfer to the CELL-FACH state, and use the uplink channel to report its own MBMS service reception information to the network side;

For the UE in the CELL-FACH state, it directly uses the uplink channel to report its MBMS service reception information to the network side.

That is to say, for the UE in the Idle state, the report is made by establishing a dedicated uplink radio resource for reporting the reception status information of the MBMS service.

Step 408, continue to execute the MBMS service flow indicated in the control information. End this process.

Step 409, the UE will include the receiving MBMS service priority list, and the UE's ability to receive MBMS services, as well as the MBMS services that the UE is receiving, the MBMS services that the UE is going to receive, whether the user rejects one or more MBMS services, etc. The receiving status information of the service and the receiving status information of the currently received non-MBMS service are reported to the network side. The reporting method in this step is exactly the same as that in step 407, and will not be repeated here.

In this embodiment, before reporting, the UE may further judge whether the service indicated in the control information is a retransmission service and the UE has correctly received the service information, and if so, it may not prepare to receive the high-priority service indicated in the control information , and even do not need to report information on service reception.

In fact, before reporting, the UE can further determine whether the control information contains frequency layer convergence (FLC) information. If it does, it will perform the frequency layer convergence operation first, and then report the reception status information of the MBMS service. If it does not include it, it will directly report it.

Step 410, continue the MBMS service process being received. End this process.

In practical applications, the UE can directly report its own MBMS service reception status information to the network side after receiving the above notification information, regardless of its own working status, which can simplify the UE's processing flow.

Because this embodiment will report the MBMS service reception status information to the network side in step 407 or step 409 . In this way, the network side can determine whether the UE is currently receiving the MBMS service being transmitted or is preparing to receive the service indicated in the control information according to the UE's receiving MBMS service priority table and the ability to receive the MBMS service. If the service indicated in , the UE can be counted when the MBMS service is recounted, otherwise it will not be counted.

For example, if the receiving capability of UE can only receive one type of MBMS service (generally, there is only one type of receiving capability of UE), and the priority of the currently received MBMS service is higher than the service indicated in the control information, it is judged that the UE is currently receiving If the MBMS service is being transmitted but is not ready to receive the service indicated in the control information, the UE will not be counted. If the receiving capability of the UE can only receive one type of MBMS service, and the priority of the currently received MBMS service is lower than the service indicated in the control information, it is judged that the UE is not currently receiving the MBMS service being transmitted, and is preparing to receive the control information If the service indicated in , the UE is counted. In this way, after the service indicated in the control information is recounted, it can be judged according to the number of users counted whether it exceeds the predetermined value. If not, the service can be delivered in PTP bearer mode, thereby reducing power resources. waste.

In addition, if the UE has the ability to receive multiple services at the same time, but because the UE only wants to receive one or several of them at present, the UE also needs to set the service it wants to receive or/and the service it is receiving in the MBMS service reception The situation information is reported to the network side. The network side judges that the UE is currently receiving the MBMS service according to the priority table, the service to be received by the UE or/and the service being received by the UE. The service that the UE wants to receive may also be a service that the UE wants to receive temporarily, and may be reported in the form of a temporarily received service list. The network side can make statistics on the UE according to the service list that the UE wants to receive temporarily, and send MBMS services. After the services in the service list that the UE wants to receive temporarily are all transmitted, the network side can delete this list.

Second preferred embodiment:

Referring to FIG. 5, FIG. 5 is a processing flowchart of the second preferred embodiment of the method of the present invention. In this embodiment, the MBMS service reception status information to be reported by the UE includes at least: the receiving MBMS service priority table, and the UE's ability to receive the MBMS service. The process includes the following steps:

In step 501, the UE receives Counting notification information of an MBMS service through a common control channel.

In step 502, the UE judges whether it is receiving another or more MBMS services or a non-MBMS service, and if yes, executes step 503; otherwise, executes step 504.

In step 503, the UE judges whether its capability can receive the MBMS service at the same time, and if yes, executes step 504; otherwise, executes step 505.

In step 504, the UE returns a Counting response indicating that the MBMS service can be received to the network side. End this process.

Step 505, if the service being received by the user includes MBMS service, then judge whether the priority of the service indicated in the Counting notification information is higher than the priority of the MBMS service being received, if yes, perform step 507; otherwise, perform step 506 .

If the service currently received by the user does not include the MBMS service but is other non-MBMS services, the user is prompted whether to switch to receive the MBMS service indicated in the notification information, and if the user chooses to receive the MBMS service, step 507 is performed; otherwise, continue to perform non-MBMS business, go to step 506.

Step 506, the UE does not respond to the Counting notification information. End this process.

Step 507, judge whether the service indicated in the Counting notification information is a retransmission service and the UE has correctly received the service information, if yes, perform step 506; otherwise, perform step 508.

In step 508, it is determined whether the Counting notification information contains frequency layer convergence (FLC) information, and if so, execute step 509 and then execute step 510; otherwise, directly execute step 510.

In step 509, a frequency layer convergence operation is performed.

The method for performing frequency layer convergence is the same as that of the prior art, and will not be repeated here.

In step 510, the UE reports the reception status information of the MBMS service to the network side along with the Counting response information.

In practical applications, as long as the UE receives the above notification information, it can directly report its own MBMS service reception information to the network side through the uplink resources along with the Counting response information, regardless of its own working conditions, which can simplify the UE's processing flow .

In this embodiment, if the UE currently receives non-MBMS services, and the user chooses to only receive the MBMS services indicated in the Counting notification information, the UE also notifies the network to disconnect the existing non-MBMS services.

In this embodiment, the method for the UE to report MBMS service reception status information to the network side is the same as step 407 or step 409 in the first embodiment shown in FIG. 4 , and will not be repeated here.

The above two processes are only preferred embodiments. In practical applications, there may be various methods for reporting MBMS service reception information. For example, after the UE reports its own MBMS service reception information, the record has been reported; when the UE When the service control information is received, it is judged whether the MBMS service reception status information has been reported, and if yes, it is not reported; otherwise, it is reported.

If the UE has reported MBMS service reception status information, it can further determine whether the MBMS service reception status has changed, and if so, report it; otherwise, do not report it.

The UE can also report the information to the network side immediately when it learns that the information of its own MBMS service reception status changes, or report the information according to the original reporting timing.

In the above two embodiments, the timing of the UE's report can be said to be determined by the network side, and it can also be determined by the user in practical applications. For example, the UE regularly reports its own MBMS service reception status information to the network side through uplink resources.

It can be seen from the above-mentioned embodiments that by applying the method for the network side of the present invention to know the situation of users receiving the MBMS service, the network side can accurately count the users receiving the MBMS service in the cell according to the service reception situation information reported by each UE. , so as to correctly determine the bearer mode and reduce the waste of power resources.
