Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, the eMBMS system architecture newly introduces 3 logical network elements: introducing MCE (multicast coordination entity) at the access network side; the core network side introduces MBMS GW (MBMS gateway) and BM-SC (broadcast multicast service center).
Besides introducing 3 additional network elements for MBMS, the MBMS architecture also involves other multiple network elements, such as base stations, MME (Mobility Management Entity), etc. Thereby resulting in a very complicated MBMS interaction procedure.
Taking V2X message broadcasting as an example, the specific flow is: the UE sends its own geographical location information or its cell id (ecgi) in a V2X message to a V2X Application Server (V2X Application Server, V2X AS, i.e., content provider in fig. 1), and the V2X message carries the Application layer data to be broadcasted, such AS accident notification.
The V2X AS maps the location information provided by the UE to a broadcast area concept understood by the MBMS system, such AS MBMS SAI (MBMS service area identities) and/or ECGI, and sends to the BM-SC, or the BM-SC determines the MBMS broadcast area based on the geographical location information provided by the V2X AS. Then BM-SC indicates the data message of application layer and MBMS SAI(s) and/or ECGI to MBMS GW (MBMS gateway) and then forwards to the related E-UTRAN node to broadcast the data.
As shown in fig. 2, an embodiment of the present invention provides a method for processing a multimedia broadcast multicast service, which is applied to a multicast broadcast control function of a multimedia broadcast multicast service system, and the method includes:
The multimedia broadcast multicast service system shown in fig. 3 includes: a multicast/broadcast control function, a connection control function, a resource allocation function, a user plane control function, a core network function, a network open function NEF/policy control function PCF;
in an optional embodiment of the present invention, the receiving, by the multicast and broadcast control function, a multicast/broadcast service establishment request includes at least one of:
the multicast broadcast control function receives a multicast/broadcast service establishment request initiated by a wireless access network function;
the multicast broadcast control function receives a multicast/broadcast service establishment request initiated by a core network function;
the multicast broadcast control function receives a multicast/broadcast service establishment request initiated by a terminal;
the multicast broadcast control function receives a multicast/broadcast service setup request initiated by an application server or a content provider.
In an optional embodiment of the present invention, the multicast/broadcast service setup request includes at least one of:
a request for switching between unicast and multicast/broadcast services;
multicast/broadcast services directly create/modify/suspend/delete requests.
Optionally, if the multicast service establishment request is a unicast-to-multicast service conversion request, the request message carries at least one of the following:
carrying a terminal ID for each terminal;
a PDU session ID is identified by a packet data unit session to be converted;
multicast/broadcast PDU session ID;
the QoS flow to be converted identifies QoS flow ID;
the IP flow that needs to be converted identifies the IP flow ID.
In an optional embodiment of the present invention, when the multicast service establishment request is a unicast-to-multicast service conversion request, the method further includes: a request to suspend a unicast bearer/multicast broadcast bearer is received.
In specific implementation, the AF (Application Function) may or may not initiate a multicast/broadcast service establishment request to the multicast broadcast control Function through the NEF (Network Exposure Function), or through the UE, or through the radio access Network Function, or through the core Network Function.
The multicast/broadcast service establishment request can be a switching request between unicast and multicast/broadcast services, can also be a direct establishment/modification/suspension/deletion request for multicast/broadcast services, and can also be a combination of the two.
If the multicast service establishment request is a unicast-to-multicast service conversion request, the request message needs to carry: for each UE, a UE ID (e.g., a UE unique identity, SUPI), a PDU session ID or a multicast/broadcast PDU session ID that needs to be converted, a QoS Flow ID (QFI) that needs to be converted, an IP flow ID that needs to be converted, and the like are carried.
At the same time of requesting unicast to multicast/broadcast service switching, it can also request to suspend unicast bearer/multicast broadcast bearer, so that it can implement faster switching later.
Case of the radio access network function initiating the request: the radio access network function may recognize that multiple UEs have the same access requirements based on the information carried by the UE IP header, thus requesting the multicast/broadcast control function to change unicast to multicast. Alternatively, the radio access network function predicts/discovers that the UE moves out of the multicast/broadcast cell range based on the UE's moving position and velocity, thus requesting the multicast/broadcast control function to modify the multicast/broadcast cell range and possibly turn the multicast/broadcast traffic into unicast.
The situation that the core network function initiates the request: a core network function, such as a location server (LMF), requests that location assistance information be delivered to UEs in a certain area via broadcast/multicast.
Case of UE initiated request: for a scenario where multiple UEs in the same geographic area request the same service, such as a cloud game, the UE may send the relevant UE ID to the multicast/broadcast control function, requesting the network to convert unicast of these UEs into multicast.
Case of application server or content provider originating request: the application server or the content provider/AF receives service requests of a plurality of UEs, learns information such as the location of the UEs through the service requests, and considers that the service information can be sent to the UEs in a multicast/broadcast mode, thereby requesting a multicast/broadcast PDU session and/or bearer to be established from a multicast/broadcast control function.
In an optional embodiment of the present invention, the multicast/broadcast configuration parameter includes at least one of:

In an optional embodiment of the present invention, the multicast broadcast control function configures the multicast/broadcast configuration parameters to the user plane management function, which includes:
the multicast broadcast control function requests the user plane management function to establish/modify/suspend/release multicast/broadcast PDU sessions and/or bearers, including at least one of:
requesting to establish a new multicast/broadcast PDU session/bearer;

requesting to change the unicast PDU session/bearer/QoS flow to a multicast/broadcast PDU session/bearer/quality of service flow QoS flow;
request to change the multicast/broadcast PDU session/bearer/quality of service flow QoS flow to a unicast PDU session/bearer/quality of service flow QoS flow.
In an optional embodiment of the present invention, the configuring, by the multicast broadcast control function, the multicast/broadcast configuration parameter to the connection management function includes:

In particular implementations, the multicast/broadcast control function determines multicast broadcast configuration parameters. The method specifically comprises the following steps:
the multicast/broadcast control function determines a multicast broadcast cell list, generates a multicast broadcast identifier and possibly a multicast broadcast key related information, multicast/broadcast starting time and determines a multicast/broadcast time-frequency resource position;
the multicast/broadcast control function issues the configuration to other related network functions:
the multicast/broadcast control function sends a multicast broadcast cell list, time/frequency resource requirements, multicast broadcast service QoS requirements and the like to the resource allocation function, and the resource allocation function feeds back the multicast broadcast time-frequency resource allocation condition;
the multicast broadcast time-frequency resource may be: dynamically scheduled resources, semi-persistently scheduled periodic resources, beam information for multicast broadcasts, and the like.
