Detailed Description

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In practical applications, the MBMS technology under LTE (Long Term Evolution) only supports relatively static MBMS service transmission, that is, when a terminal device enters a certain cell supporting MBMS, only the MBMS service being transmitted in the cell can be received, and in the 5G MBS technology, at least for the MBS service of the multicast type, it is supported to adjust the multicast service transmission area as required, that is, the cell supporting the MBS Function, and it is determined whether to establish an MBS data transmission channel with an UPF (User Port Function) or not according to the presence or absence of the terminal device interested in the MBS service in the coverage area, and open MBS data transmission of an air interface. That is, a cell supporting MBS function, may trigger the transmission of MBS service data by the cell after a first terminal device, which is required for receiving a specific MBS service, enters the cell coverage.

Specifically, the most significant characteristic of the multicast service, which is different from the broadcast service, is that the multicast service is only transmitted for a group of specific terminal devices, that is, the terminal devices need to perform a group joining process with a Non-access stratum (NAS) on the network side before receiving the multicast service data.

Therefore, a terminal device that is required to receive the multicast service needs to be camped on a network (PLMN) supporting the MBS function, so as to be able to successfully complete the process of joining the MBS service group.

Currently, the access network sharing (RAN sharing) is shown in fig. 1, and it can be understood that the access network sharing function is a basic function supported by both 4G and 5G, that is, the same NG-RAN node, which can be shared by multiple networks (PLMNs), that is, a terminal device supporting any shared network (PLMN) can complete registration and use the services (including MBS services) provided by the terminal device connected to the corresponding network (PLMN) through the NG-RAN radio access network node.

Specifically, different PLMN networks support different functions, that is, some PLMN networks support the MBS function and some PLMN networks do not support the MBS function, so that if the terminal device determines to initiate a Join group (Join group) process according to information about whether a cell supports MBS, it may initiate an unnecessary request for adding an MBS service group to a core network that does not support MBS, and the process of adding an MBS service group cannot be successful, which eventually increases extra power consumption of the terminal device and prolongs the time for establishing the MBS service.

In order to solve the above problems, according to the present application, after receiving a control message, a terminal device may select a target cell corresponding to a target PLMN network with MBS capability according to MBS capability indication information corresponding to each PLMN network identifier by sending, at an access network side, MBS capability indication information including PLMN network identifiers supported by each cell itself and MBS capability indication information corresponding to each PLMN network identifier. Therefore, when the terminal equipment needs to receive the MBS service, the PLMN network with the MBS capability is selected according to the MBS capability indication information of the PLMN network provided by the access network side when the network selection is carried out, the extra power consumption of the terminal equipment and the establishment time of the MBS service are avoided, and the service processing efficiency of multicast broadcasting is improved.

The following describes in detail a method, an apparatus, a device, and a storage medium for indicating MBS capability of a multicast broadcast service provided in the present application with reference to the accompanying drawings.

Fig. 2 is a flowchart illustrating a method for indicating MBS capability of a multicast broadcast service according to an embodiment of the present application.

The execution main body of the embodiment of the present application is the multicast broadcast service MBS capability indication device provided by the present application, and the multicast broadcast service MBS capability indication device may be configured in any access network side device, so that the access network side device may execute a multicast broadcast service MBS capability indication function.

The access network side device may be a base station, and the base station may include multiple cells that provide services for the terminal device. A base station may also be referred to as an access point, or a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal device devices, or by other names, depending on the particular application. The access network side device may be configured to exchange the received air frame with an Internet Protocol (IP) packet as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The access network side device may also coordinate the management of attributes for the air interface. For example, the Access network side device according to the embodiment of the present application may be a network side device (Base Transceiver Station, BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), may also be a network side device (NodeB) in a Wideband Code Division Multiple Access (WCDMA), may also be a evolved network side device (evolved Node B, eNB or e-NodeB) in a Long Term Evolution (LTE) System, may also be a 5G Base Station (gb) in a Home evolved Node B (HeNB), relay Node (relay Node), home base station (femto), pico base station (pico), etc., but the embodiments of the present application are not limited thereto. In some network structures, the access network side device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, and the Centralized Unit and the Distributed Unit may also be geographically separated.

As shown in fig. 2, the method for indicating the MBS capability of the multicast broadcast service is used for accessing a network, and includes the following steps:

step 101, sending a control message, wherein the control message comprises: PLMN network identifications supported by each cell and multicast broadcast service MBS capability indication information corresponding to each PLMN network identification.

In the embodiment of the present application, a receiving network side may obtain a control message that includes a PLMN network identifier supported by each cell and multicast broadcast service MBS capability indication information corresponding to each PLMN network identifier, where it may be understood that an access network may include one or more cells, PLMN networks that may be supported by each cell may be the same or different, and a unique PLMN network may be identified by using the PLMN network identifier, for example, PLMN network identifier 1, PLMN network identifier 2, and PLMN network identifier 3 are used to identify three different PLMN networks.

In the embodiment of the present application, the access network side device is shared by multiple PLMN networks, and may acquire information of the multiple PLMN networks, for example, whether the PLMN network has MBS capability, that is, in the multiple PLMN networks shared with the NG-RAN radio access network node, some PLMN networks have MBS capability, that is, support MBS function, and some PLMN networks do not have MBS capability, that is, do not support MBS function, and may assign corresponding MBS capability indication information to each PLMN network identifier, for example, MBS capability indication information corresponding to PLMN network identifier 1 is X, which indicates that there is MBS capability; for another example, the MBS capability indication information corresponding to the PLMN network identifier 1 is Y, which indicates that there is no MBS capability.

In the embodiment of the present application, the control message has various forms, and may be selected and set according to an application scenario, as a possible implementation manner, the control message is a Radio Resource Control (RRC) message, where the RRC message includes: PLMN network identifications supported by each cell and MBS capability indication information corresponding to each PLMN network identification.

In the embodiment of the present application, the RRC message may have various forms, for example, an existing system information block or an additional system information block.

In the embodiment of the present application, the existing System Information block may be, for example, SIB1(System Information Blocks 1, System Information block 1), and in a 5G network, SIB1 carries scheduling that allows terminal devices to access and other System Information, and may send a control message in formats such as a signaling bearer, a transport channel, and a physical channel.

In the embodiment of the application, the radio resource control RRC message is sent, so that limited radio network resources can be fully utilized possibly under the condition of meeting the requirement of service quality, and the service capacity and the resource utilization rate are improved.

In the embodiment of the present application, in order to further improve the accuracy of the control message, the RRC message may be dedicated to only send the PLMN network identifier supported by each cell and MBS capability indication information corresponding to each PLMN network identifier.

The method for indicating the multicast broadcast service MBS capability of the embodiment of the application sends a control message through an access network side, wherein the control message comprises the following steps: the method comprises the steps that PLMN network identifications supported by each cell and multicast broadcast service MBS capability indication information corresponding to each PLMN network identification, so that terminal equipment receives control messages, and selects a target cell corresponding to a target PLMN network with MBS capability according to the MBS capability indication information corresponding to each PLMN network identification. Therefore, the terminal equipment can select the PLMN with the MBS capability according to the MBS capability information of the PLMN provided by the access network side when the terminal equipment needs to receive the MBS service and performs network selection, thereby avoiding the extra power consumption of the terminal equipment and the establishment time of the MBS service and improving the service processing efficiency of multicast broadcasting.

In order to implement the above embodiments, the present application further provides a receiving method for MBS capability indication.

Fig. 3 is a flowchart illustrating a receiving method for MBS capability indication according to a second embodiment of the present application.

The execution main body of the embodiment of the present application is a receiving apparatus for MBS capability indication provided by the present application, and the receiving apparatus for MBS capability indication may be configured in any terminal device, so that the terminal device may execute a receiving function for MBS capability indication. The terminal device may specifically be a sending terminal device.

In the embodiments of the present application, the terminal device may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. In different systems, names of terminal devices may be different, for example, in a 5G system, a terminal device may be referred to as a User Equipment (UE). A wireless terminal device may communicate with one or more Core Networks (CN) via a Radio Access Network (RAN), and may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer having the mobile terminal device, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, which exchanges languages and/or data with the RAN. For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs) are used. The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user equipment (user device), which are not limited in this embodiment.

As shown in fig. 3, the receiving method of MBS capability indication, for a terminal device, may include the following steps:

step 201, receiving a control message, wherein the control message includes: PLMN network identifications supported by each cell and MBS capability indication information corresponding to each PLMN network identification.

In the embodiment of the application, after the access network sends the control message, the terminal device receives the control message, and the control message includes PLMN network identifiers supported by each cell and MBS capability indication information corresponding to each PLMN network identifier.

In the embodiment of the present application, each PLMN network identifier is given corresponding MBS capability indication information, for example, the MBS capability indication information corresponding to PLMN network identifier 1 is X, which indicates that the PLMN network identifier has MBS capability; for example, the MBS capability indication information corresponding to the PLMN network identifier 1 is Y, which indicates that there is no MBS capability, so that the terminal device can quickly and accurately determine whether each PLMN network has MBS capability according to the MBS capability indication information.

In this embodiment of the present application, there are many ways for an access network side to send a control message, and as a possible implementation way, a Radio Resource Control (RRC) (radio Resource control) message may be sent, so that a terminal device may receive the RRC message, where the RRC message includes: PLMN network identifications supported by each cell and MBS capability indication information corresponding to each PLMN network identification.

In the embodiment of the present application, the existing System Information block may be, for example, SIB1(System Information Blocks 1, System Information block 1), in a 5G network, SIB1 carries scheduling that allows the terminal device to access and other System Information, and may send the control message through formats such as a signaling bearer, a transport channel, and a physical channel.

Step 202, according to the MBS capability indication information corresponding to each PLMN network identifier, selecting a target cell corresponding to a target PLMN network with MBS capability.

In this embodiment of the present application, after obtaining MBS capability indication information corresponding to each PLMN identifier, the terminal device may select a target cell corresponding to a target PLMN network with MBS capability, and the specific selection manner may be set according to an application scenario, that is, the terminal device includes an Access Stratum (as) and a Non-Access Stratum (NAS, Non-Access Stratum), and both the Access Stratum (as) and the Non-Access Stratum (NAS) of the terminal device may obtain control information, for example, as follows.

In a first example, the non-access layer receives PLMN network identifiers supported by each cell and MBS capability indication information corresponding to each PLMN network identifier, the non-access layer selects a target PLMN network with MBS capability according to the MBS capability indication information corresponding to each PLMN network identifier, and sends a network identifier of the target PLMN network to the access layer, and the access layer selects a corresponding target cell according to the network identifier of the target PLMN network.

In a second example, the non-access layer selects a network identifier of a candidate PLMN network to send to the access layer, the access layer receives a PLMN network identifier supported by each cell and MBS capability indication information corresponding to each PLMN network identifier and detects whether a network corresponding to the network identifier of the candidate PLMN network is a target PLMN network with MBS capability, if the access layer detects that the candidate PLMN network is the target PLMN network with MBS capability, the access layer selects a corresponding target cell according to the network identifier of the candidate PLMN network, and if the access layer detects that the candidate PLMN network is not the target PLMN network with MBS capability, the access layer selects the target PLMN network with MBS capability and the corresponding target cell according to the MBS capability indication information corresponding to each PLMN network identifier.

According to the receiving method of the MBS capability indication, the terminal equipment receives the control message, and selects the target cell corresponding to the target PLMN network with MBS capability according to the MBS capability indication information corresponding to each PLMN network identifier. Therefore, the terminal equipment can select the PLMN with the MBS capability according to the MBS capability information of the PLMN provided by the access network side when the terminal equipment needs to receive the MBS service and performs network selection, thereby avoiding the extra power consumption of the terminal equipment and the establishment time of the MBS service and improving the service processing efficiency of multicast broadcasting.

In a possible implementation manner of the embodiment of the present application, an access network side sends a control message to notify a terminal device whether each shared PLMN network has MBS capability, so that the terminal device that has a need for receiving the MBS capability can select a PLMN network having the MBS capability to use an MBS service as needed, and after a non-access layer on the terminal device side obtains MBS capability indication information, the PLMN network can be selected according to the MBS capability indication information.

Fig. 4 is a flowchart illustrating a receiving method for MBS capability indication according to a third embodiment of the present application.

As shown in fig. 4, the receiving method of the MBS capability indication may include the following steps:

step 301, receiving a radio resource control RRC message, wherein the RRC message includes: PLMN network identifications supported by each cell and MBS capability indication information corresponding to each PLMN network identification.

The execution process of step 301 may refer to the execution process of the above embodiment, which is not described herein again.

Step 302, the non-access layer receives PLMN network identifiers supported by each cell and MBS capability indication information corresponding to each PLMN network identifier.

Step 303, the non-access layer selects a target PLMN network with MBS capability according to the MBS capability indication information corresponding to each PLMN network identifier, and sends the network identifier of the target PLMN network to the access layer.

And step 304, the access layer selects a corresponding target cell according to the network identifier of the target PLMN network.

In the embodiment of the application, the terminal device comprises an access layer and a non-access layer, the non-access layer receives PLMN network identifiers supported by each cell and MBS capability indication information corresponding to each PLMN network identifier, then directly selects a PLMN network with MBS capability according to the MBS capability indication information and sends the PLMN network with MBS capability to the access layer, and the access layer selects a corresponding target cell according to the network identifier of the target PLMN network.

When the MBS capability indication information contains the PLMN network identifications with the MBS capabilities, the common PLMN network can be selected according to the historical access information of the terminal equipment, or the network identification of the target PLMN network can be obtained from the PLMN network identifications with the MBS capabilities in a mode of presetting the PLMN network access priority and the like, so that the use requirement of the terminal equipment is further met.

Step 305, joining the multicast service group in the target cell, and receiving the multicast service data of the multicast service group.

In the embodiment of the application, after the terminal device NAS layer initiates joining of the multicast service group, the terminal device receives the multicast service data, so that the service processing efficiency of multicast broadcasting is improved.

AS an example of a scenario, AS shown in fig. 5, an information interaction process of a terminal NAS layer, a terminal AS layer, an access network, and a core network is performed.

Specifically, step 1, the terminal device non-access stratum NAS triggers a network selection process; step 2, an access layer AS of the terminal equipment needing to receive the MBS service starts to search the available PLMN network on the supported frequency band, and acquires the MBS capability information corresponding to the PLMN network through RRC message; step 2, after the access layer AS of the terminal equipment finishes searching the available PLMN networks, reporting the searched available PLMN network list and MBS capacity information corresponding to each available PLMN network to the non-access layer NAS of the terminal equipment; step 4, the non-access layer of the terminal equipment selects the network with MBS capability and informs the terminal access layer of the network with MBS capability by considering the MBS capability information of the network on the basis of the traditional network selection strategy, and the access layer selects the corresponding cell according to the network with MBS capability; and step 5, after the terminal equipment resides in the cell, the terminal NAS layer initiates a process of adding a group of the MBS service and receives the multicast service data.

The receiving method of MBS capability indication in the embodiment of the present application receives radio resource control RRC message through a terminal device, where the RRC message includes: the method comprises the steps that PLMN network identifications supported by each cell and MBS capacity indication information corresponding to each PLMN network identification, a non-access layer receives the PLMN network identifications supported by each cell and the MBS capacity indication information corresponding to each PLMN network identification, the non-access layer selects a target PLMN network with MBS capacity according to the MBS capacity indication information corresponding to each PLMN network identification and sends the network identification of the target PLMN network to an access layer, the access layer selects a corresponding target cell according to the network identification of the target PLMN network, a multicast service group is added to the target cell, and multicast service data of the multicast service group are received. Therefore, when the terminal equipment needs to receive the MBS service, the PLMN network with the MBS capability is selected according to the MBS capability information of the PLMN network provided by the access network side when the network selection is carried out, thereby avoiding the extra power consumption of the terminal equipment and the establishment time of the MBS service and improving the service processing efficiency of multicast broadcasting.

In another possible implementation manner of this embodiment, the access network side sends a control message to notify the terminal device whether each shared PLMN network has MBS capability, so that the terminal device that has a need for receiving the MBS capability can select a PLMN network having MBS capability to use MBS service as needed, after acquiring MBS capability indication information, the non-access layer on the terminal device side does not select a PLMN network according to the MBS capability indication information, and selects the PLMN network through the access layer, which is described in detail below with reference to embodiment 4.

Fig. 6 is a flowchart illustrating a receiving method for MBS capability indication according to a fourth embodiment of the present application.

As shown in fig. 6, the receiving method of the MBS capability indication may include the following steps:

step 401, receiving a radio resource control RRC message, where the RRC message includes: PLMN network identifications supported by each cell and MBS capability indication information corresponding to each PLMN network identification.

The execution process of step 401 may refer to the execution process of the above embodiments, which is not described herein again.

In step 402, the non-access stratum selects a network identifier of a candidate PLMN network and sends the network identifier to the access stratum.

In step 403, the access layer receives PLMN network identifiers supported by each cell and MBS capability indication information corresponding to each PLMN network identifier, and detects whether a network corresponding to the network identifier of the candidate PLMN network is a target PLMN network with MBS capability.

Step 404, if the access layer detects that the candidate PLMN network is the target PLMN network with MBS capability, the access layer selects a corresponding target cell according to the network identifier of the candidate PLMN network.

Step 405, if the access layer detects that the candidate PLMN network is not the target PLMN network with MBS capability, the access layer selects the target PLMN network with MBS capability and the corresponding target cell according to the MBS capability indication information corresponding to each PLMN network identifier.

In the embodiment of the present application, the network identifier of the candidate PLMN network selected by the non-access layer may have MBS service capability or may not have MBS service capability, that is, the non-access layer does not select the candidate PLMN network according to the MBS capability indication information corresponding to each PLMN network identifier, so that the access layer is required to receive the PLMN network identifier supported by each cell and the MBS capability indication information corresponding to each PLMN network identifier, and detect whether the network corresponding to the network identifier of the candidate PLMN network is the target PLMN network with MBS capability, thereby further ensuring that the PLMN network with MBS capability is selected, and avoiding additional power consumption of the terminal device and establishment time of the MBS service.

In the embodiment of the application, if the access layer detects that the candidate PLMN network is the target PLMN network with MBS capability, the access layer directly selects the corresponding target cell according to the network identifier of the candidate PLMN network, and when the access layer detects that the candidate PLMN network is not the target PLMN network with MBS capability, the access layer selects the target PLMN network with MBS capability and the corresponding target cell according to the MBS capability indication information corresponding to each PLMN network identifier, thereby ensuring that the PLMN network with MBS capability is selected.

Step 406, joining the multicast service group in the target cell, and receiving the multicast service data of the multicast service group.

AS an example of a scenario, AS shown in fig. 7, an information interaction process of a terminal NAS layer, a terminal AS layer, an access network, and a core network is performed.

Specifically, in step 1, a terminal device which needs to receive the MBS multicast service starts cell selection, and the terminal AS layer has received a candidate network selected by the NAS layer; step 2, the terminal device tries to select a proper cell to reside, reads a PLMN network list supported by the cell and corresponding MBS capability information indicated in the RRC message of the searched cell, judges whether the cell supports the PLMN with MBS capability or an equivalent network (equivalent PLMN) with MBS capability specified by a non-access stratum, and selects a cell connected to the specified PLMN or the equivalent network (equivalent PLMN) with MBS capability; step 3, after the terminal equipment resides in the cell, the terminal NAS layer initiates a process of adding a group of MBS service; and 4, the terminal equipment receives the multicast service data.

In the embodiment of the present application, the equivalent network with MBS capability may be understood as that the candidate network PLMN1 includes sub-networks a, b, and c, where sub-network a has the same MBS service capability as the candidate network PLMN1, and may select the cell access corresponding to the equivalent network, i.e., sub-network a.

Therefore, when a terminal equipment side required for receiving the multicast service selects a cell according to the MBS capability indication information of the PLMN provided by the access network side, the terminal equipment side selects the cell connected to the PLMN with MBS capability or an equivalent network (equivalent PLMN) with MBS capability selected by the non-access stratum, and further completes the multicast related signaling flow and starts to receive the multicast service data on the corresponding cell.

The receiving method of MBS capability indication in the embodiment of the present application receives a radio resource control RRC message through a terminal device, where the RRC message includes: the non-access layer selects the network identifier of the candidate PLMN network and sends the network identifier to the access layer, the access layer receives the PLMN network identifier supported by each cell and the MBS capability indication information corresponding to each PLMN network identifier and detects whether the network corresponding to the network identifier of the candidate PLMN network is the target PLMN network with MBS capability, if the access layer detects that the candidate PLMN network is the target PLMN network with MBS capability, the access layer selects the corresponding target cell according to the network identifier of the candidate PLMN network, if the access layer detects that the candidate PLMN network is not the target PLMN network with MBS capability, the access layer selects the target network with MBS capability and the corresponding target cell according to the MBS capability indication information corresponding to each PLMN network identifier, and adds the multicast service group in the target cell, and receiving the multicast service data of the multicast service group. Therefore, when the terminal equipment needs to receive the MBS service, the PLMN network with the MBS capability is selected according to the MBS capability information of the PLMN network provided by the access network side when the network selection is carried out, thereby avoiding the extra power consumption of the terminal equipment and the establishment time of the MBS service and improving the service processing efficiency of multicast broadcasting.
