Problems solved by technology

However, the newly created MBMS UE context cannot be associated with a PDP (Packet Data Protocol) context. In this way, during the execution of the subsequent MBMS service, the BM-SC may not be able to transmit information normally, resulting in the failure of the normal development of the MBMS service.

Embodiment 1

[0033] In this embodiment, in order to solve the problem that the user equipment is associated with the bearer in implementing the MBMS service, the method of creating a corresponding PDP context for the user equipment before initiating the request to activate the MBMS context is adopted, and then activate the MBMS context Processing of requests, etc.;

[0034] Such as figure 2 As shown, the specific implementation process of this embodiment includes:

[0035] Step 1: If the user equipment UE does not have a PDP (Packet Data Protocol) context, it will create a corresponding PDP context through the PDP context request PDP Context Request message interacted with the SGSN and GGSN on the network side. The PDP context can be used but not limited to Use the PDP context used in the key transfer process;

[0036] Step 2: If the user equipment UE does not support the IGMP or MLD protocol, then directly send an Activate MBMS Context Request message to the SGSN to join the MBMS multi...

Embodiment 2

[0051] In this embodiment, in order to solve the problem associated with the bearer of the user equipment in implementing the MBMS service, a method of creating a corresponding PDP context for the user equipment in the process of activating the MBMS context request slice is adopted, and then proceed to the subsequent activation of the MBMS Processing of contextual requests, etc.;

[0052] Such as image 3 As shown, the specific implementation process of this embodiment includes:

[0053] Step 1: If the user equipment UE does not support the IGMP or MLD protocol, it can directly initiate an Activate MBMS Context Request to the SGSN to request to join the MBMS multicast group;

[0054] Specifically, the corresponding request message may include information such as IP multicast address, APN, MBMS_NSAPI, and MBMS bearer capabilities;

[0055] Step 2: After receiving the request message sent by the user equipment UE, the SGSN sends a Create MBMS UE Context Request message to the ...

Abstract

The invention relates a method for realizing load bearing correlation in a multicast broadcasting service and a device thereof. The method comprises the steps that: first, a load bearing connection context is established for user equipment which does not support a multicast management protocol, and the context of a multicast broadcasting service user is established according to the multicast broadcasting service conducted by the user equipment requesting for joining in a multicast group; and then the load bearing connection context is correlated to the context of the multicast broadcasting service user, so as to realize load bearing correlation operation. Therefore, the embodiment of the invention can cause the user equipment which does not support a multicast management protocol to be able to correlate the load bearing connection context and the context of the multicast broadcasting service user after obtaining the context of the multicast broadcasting service user during the process of joining the multicast group, so as to ensure the user equipment can obtain the multicast broadcasting service reliably.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a technology for developing multicast broadcasting services. Background technique [0002] In order to meet the development needs of various application services such as video on demand and online games, more and more multicast transmission methods are used in the communication network as the information dissemination method in the network. Multicast technology is a routing mechanism that simultaneously transmits information from an information source to multiple receivers to save network bandwidth. [0003] Currently, the 3GPP organization has proposed an MBMS (Multimedia Broadcast / Multicast Service) technical solution. Said MBMS can not only provide text and multimedia information, but can also completely combine various multicast services provided on the Internet. [0004] Such as figure 1 As shown, the server as the multicast source only sends information onc...
