Embodiment 1

[0044] The MME pool update method of this embodiment, such as Picture 1-1 shown, including the following steps:

[0045] Step S101: The eMBMS gateway receives the service area report message of the MME node, and the service area report message includes the service area information managed by the MME node;

[0046] In this step, the MME Pool refers to an area composed of one or more MMEs, which is a collection of complete Service Areas. Each eNodeB in the MME Pool is fully interconnected with the MME; different MME Pools can be superimposed on each other. The eNBs in the area can simultaneously establish S1 connections with some MMEs in the two MME pools. The UE does not need to change the serving MME when it moves in the Service Area of ​​the MME Pool. Different MME node managers have their own managed nodes, such as Figure 1-2As shown, there are two MME Pools, namely MME Pool1 and MME Pool2. Among them, MME Pool1 has MME1 and MME2, and the service area information managed...

Embodiment 2

[0052] The MME pool update method of this embodiment, such as figure 2 shown, including the following steps:

[0053] Step S201: Embms-Gw sends a GTP request message to MME, requesting MME to report Service Area information;

[0054] Step S202: After the MME receives the MBMS-related service message, it checks the field, and if the Embms-Gw requests the MME to report the Service Area information, it reports the service area information managed by the node; if this function is not supported, it is automatically ignored;

[0055] Step S203: Embms-Gw receives the GTP message sent by the MME, if it carries Service Area information, saves the relevant information, matches the same MME and automatically maintains the MME POOL list;

[0056] Step S204: Use the generated data to implement MME POOL-related business processes.

[0057] It is worth noting that the following table is a format that has been described in detail in Protocol 29274 in the Service Area format in this embodim...

Embodiment 3

[0060] This embodiment provides an eMBMS gateway 300, such as image 3 As shown, it includes a receiving module 301 and an updating module 302:

[0061] The receiving module is configured to receive a service area report message of the MME node at 301, where the service area report message includes service area information managed by the MME node;

[0062] The update module 302 is used for updating the MME pool according to the service area report message.

[0063] This embodiment also provides an eMBMS gateway 300, such as Figure 4 As shown, the eMBMS gateway 300 further includes a request module 303, which is configured to send a service area report request message to the MME node before the eMBMS gateway receives the service area report message of the MME node.

[0064] Specifically, the service area report message is a service message; the way the service area report message includes the service area information managed by the MME node includes: carrying the service are...

Abstract

The invention provides an MME (mobility management entity) pool update method and system, an eMBMS (enhanced Multimedia Multicast Service Gateway), and an MME node and belongs to the field of communication. The method comprises the steps that the enhanced multimedia multicast service gateway receives service area report messages of the mobility management entity nodes, wherein the service area report messages comprise service area information managed by the mobility management entity nodes; and the enhanced multimedia multicast service gateway updates mobility management entity pools according to the service area information. Compared with the prior art, the method, the system, the gateway and the node have the advantages that the enhanced multimedia multicast service gateway eMBMS GW can intelligently sense MME POOL functions, the MME POOL functions are prevented from being improved by manually configuring an MME POOL list, under the condition that a network is changed, the network maintenance cost is reduced, and the network management efficiency is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to an MME pool update method, system, eMBMS gateway, and MME node. Background technique [0002] Enhanced Multimedia Broadcast Multicast Service (eMBMS) technology is based on the enhanced broadcast multicast technology stipulated in the 3rd Generation Partnership Project (3GPP) R9 protocol, and is an efficient video bearer technology in the mobile field one. It is an advanced mobile data transmission technology that enables operators to significantly reduce the cost of providing large-bandwidth content such as video and audio to multiple users at the same time on the Long Term Evolution (LTE) system network. [0003] The mobility management entity (MME) is the key control plane node in the EPC system, and it is usually set in a centralized manner during deployment; once the MME device fails, the damage caused is often large, and the recovery time of the failure is long, affecting user p...
