Embodiment 1

[0045] image 3 It is the flow chart of MBMS session start in this embodiment, the MBMS session start process is initiated by the core network, and is used to require E-UTRAN / UTRAN to notify UE to start the current MBMS session, and to establish MBMS signaling connection, MBMS session in this embodiment The start process may specifically include the following steps:

[0046] Step 201, the BM-SC sends a session start request to the MBMS GW, which carries the downlink node information, the MBMS bearer context and the group ID (Group ID) of the device group that needs to start the current MBMS session in the session start request;

[0047] Here, the downlink node information may be an MME / SGSN list of the current MBMS session, and the MME / SGSN list includes information of each MME / SGSN related to the current MBMS session, such as information such as the ID and address of the MME / SGSN.

[0048] Here, the group identifier of the device group that needs to start the current MBMS se...

Embodiment 2

[0060] Figure 4It is the flow chart of MBMS session termination in this embodiment. The current MBMS session does not generate any data transmission within a period of time. The core network needs to initiate the termination process of the current MBMS session, mainly requesting E-UTRAN / UTRAN to notify the UE to terminate the current MBMS session, Release the signaling connection of the current MBMS session. In this embodiment, the session end request increases the Group ID that carries the device group that needs to terminate the current MBMS session. The MBMS session end process of this embodiment may specifically include the following steps:

[0061] Step 301, the BM-SC sends a session end request to the MBMS GW, the session end request carries downlink node information and the Group ID of the device group that needs to terminate the current MBMS session;

[0062] Here, the downlink node information may be an MME / SGSN list of the current MBMS session, and the MME / SGSN lis...

Embodiment 3

[0072] Figure 5 It is the MBMS session update flow chart of this embodiment. The MBMS session update process is initiated by the core network, mainly when the MBMS session is in progress, the SGSN notifies the UE to update the routing (RA, RootingArea) list or update the bearer parameters. In the present embodiment, the Group ID of the device group that needs to update the current MBMS session is increased in the session update process, and the specific implementation process of the present embodiment may include the following steps:

[0073] Step 401. The BM-SC sends a session update request to the MBMS GW, the session update request carries bearer parameters and the Group ID of the device group that needs to perform the current MBMS session update;

[0074] Here, the bearer parameters may include parameters such as Quality of Service (QoS, Quality of Service).

[0075] Here, the session update request also includes downlink node information, and the downlink node informati...

Abstract

The invention discloses an MBMS (Multimedia Broadcasting/Multicast Service) triggering method, which comprises the following steps: BM-SC (Broadcast/Multicast Service Center) sends a group identifier of an equipment group for carrying out current MBMS conversation operation through a control signaling to a user terminal; and the user terminal triggers the user terminal to carry out the current MBMS conversation operation according to the group identifier. The invention also discloses an MBMS triggering system which is capable of greatly saving wireless resources, reducing BM-SC service data processing quantity, improving the service processing efficiency of the user terminal such as MTC (Multimedia Technologies Center) and improving the triggering efficiency of the MBMS business.

Description

technical field [0001] The present invention relates to machine type communication (MTC, Machine Type Communication) equipment access technology, in particular to a multimedia broadcast / multicast service (MBMS, Multimedia Broadcast / Multicast Service) triggering method and system. Background technique [0002] Machine-to-machine (M2M, Machine to Machine) narrowly defines machine-to-machine communication, and broadly defines networked applications and services centered on machine-terminal intelligent interaction. M2M is an informatization solution based on intelligent machine terminals and using multiple communication methods as access means to provide customers with informatization solutions to meet customers' informatization needs in monitoring, command and dispatch, data collection and measurement. The data communication between one or more machines is called machine type communication (MTC, Machine Type Communication). In this case, human-computer interaction is less requi...
