Problems solved by technology

[0010] However, in the related art, in the scenario where the multicast mechanism is used to fan-out group operations to members, the CSE saves the visited group and the multicast group related to the multicast group (Multicast Group) At the same time, in the 3GPP network, the multimedia broadcast multicast service gateway (MBMS GW) allocates multicast group information for the multicast group, which may cause conflicts between the multicast group information stored by the CSE and the multicast group information allocated by the MBMS GW

Embodiment 1

[0046] The processing method of the multicast group information provided by this embodiment is as follows: figure 2 shown, including:

[0047] Step 110, the first bearer network element receives the multicast group information allocated by the common service entity CSE;

[0048]In this embodiment, the first bearer network element receives the multicast group information delivered by the NSE, and the multicast group information is allocated by the CSE where the group is located and sent to the NSE. Wherein, the multicast group information includes a multicast address, or a multicast address and an address type. In an example, the CSE sends a group message request (Group MessageRequest) to the NSE, carrying the multicast group information and an external group ID (External Group ID). The mapping relationship between the external group identifier and the group identifier used on the bearer network is configured on the bearer network.

[0049] Step 120, the network element of ...

Embodiment 2

[0076] The processing method of the multicast group information provided by this embodiment is as follows: Figure 4 shown, including:

[0077] Step 210, the second bearer network element receives the multicast group information allocated by the common service entity CSE;

[0078] In this embodiment, the first bearer network element is a BM-SC, and the second bearer network element is an MBMS GW; A session request, the multicast group information carried in the session request, where the multicast group information includes a multicast address, or a multicast address and address type.

[0079] In this embodiment, the session request is a session update request or a session start request, and the session update request (Session Update Request) or session start request (Session Start Request) also carries the temporary mobile group corresponding to the multicast group information Identifies TMGI and stream id.

[0080] Step 220, the network element of the second bearer networ...

Embodiment 3

[0090] This embodiment provides a method for processing multicast group information, such as Figure 6 shown, including:

[0091] Step 310, the public service entity CSE distributes the multicast group information;

[0092] In this embodiment, the CSE is the CSE where the group is located, and the multicast group information includes a multicast address, or a multicast address and address type.

[0093] In step 320, the CSE sends the assigned multicast group information to the network element of the bearer network through a multicast service request, and triggers the network element of the bearer network to create or update local multicast group information.

[0094]In this embodiment, the CSE sends a group message request (Group MessageRequest) to the bearer network service entity NSE, carrying the multicast group information, and transmits the multicast group information to the bearer network network element through the NSE ; The group message request also carries an exter...

Abstract

A method, device and system for processing multicast group information. The method includes: receiving the multicast group information allocated by the public service entity CSE through the first bearer network element; the first bearer network element creates or updates the local multicast group information according to the received multicast group information . It realizes that the bearer network element creates or updates the local multicast group information according to the multicast group information allocated by the CSE, thereby avoiding possible conflicts between the multicast group information saved by the CSE and the multicast group information allocated by the MBMS GW.

Description

technical field [0001] The invention relates to communication technology, in particular to a method, device and system for processing multicast group information. Background technique [0002] oneM2M is an international standard organization under ETSI (European Telecommunications Standards Institute) dedicated to M2M (machine-to-machine communication) and IoT (Internet of Things). Its goal is to develop an IoT architecture and related technical standards to eventually realize machine-to-machine communication across different sectors and industries. [0003] The functional architecture of oneM2M is as follows: figure 1 As shown, the following functional entities are included: [0004] Application Entity (Application Entity, AE): The application entity is an entity in the application layer that implements the logic of the M2M application service. Each application service logic may reside in multiple M2M nodes and / or multiple times on a single M2M node. Each execution inst...
