Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
As shown in fig. 1-1, the MME pool updating method of this embodiment includes the following steps:
step S101: the eMBMS gateway receives a service area reporting message of the MME node, wherein the service area reporting message comprises service area information managed by the MME node;
in this step, an MME Pool, i.e. an MME Pool, refers to an Area composed of one or more MMEs, and is a complete set of Service Area areas, and each eNodeB in the MME Pool is fully interconnected with the MME; different MME Pool can be mutually overlapped, and the eNB in the overlapping area can simultaneously establish S1 connection with some MME in two MME pools. The UE moves in the Service Area within the MME Pool without replacing the serving MME. As shown in fig. 1-2, there are two MME Pool, MME Pool1 and MME Pool2, where MME Pool1 includes MME1 and MME2, and the Service Area information managed by MME1 includes 4 Service areas, which are SA1 for Service Area1, SA2 for Service Area2, SA3 for Service Area3, and SA4 for Service Area 4. Similarly, MME2 also manages four regions SA1, SA2, SA3, and SA 4. MME Pool2 includes MME3 and MME4, and MME3 and MME4 manage Service Area information simultaneously in 4 Service areas, which are respectively SA5 for Service Area5, SA6 for Service Area6, SA8 for Service Area7 and SA7 for Service Area 8.
Step S102: and the eMBMS gateway updates the MME pool according to the service area reporting message.
In this step, the eMBMS gateway stores the relevant information, and automatically maintains an MME POOL list in match with the same MME.
Specifically, in step S102, before the eMBMS gateway receives the service area reporting message of the MME node, the method further includes: and the eMBMS gateway sends a service area reporting request message to the MME node. Specifically, the request message may be a GTP request message. Namely by: and after the eMBMS gateway sends the request, the MME node reports the service area of the MME node. Therefore, the eMBMS gateway can manage the MME node more actively, and unnecessary processing is reduced. Certainly, other manners may also be adopted, such as sending the request periodically according to preset time, or actively reporting periodically by the MME node.
In order to reduce unnecessary information types, preferably, the service area reports the message as a service message; the mode that the service area reporting message comprises the service area information managed by the MME node comprises the following steps: carrying service area information managed by the MME node in an extension field carried by the service message; or adding a field carrying the service area information managed by the MME node in the service message. It should be understood that, the service area information managed by the MME node is reported through a service packet existing in itself, if the service packet itself has an extension field, the service area information managed by the MME node is placed in the extension field, and if not, a field may be added in the service packet to carry the service area information managed by the MME node. Of course, other methods that may report the service area information managed by the MME node to the eMBMS gateway should be included. Specifically, the service packet includes interactive packets such as echo, mbms session start, mbms session update, and the like. For example, the MME and the Embms-GW may all carry a private extension field in the interactive information echo, mbms session start, and mbms session update messages, and the private extension carries Service Area information. The eMBMS gateway Embms-GW saves Service Area information for subsequent MME POOL related services. Or adding fields to carry Service Area information in the information echo, mbms session start, mbms session update message of MME and Embms-GW. The Embms-GW stores Service Area information for subsequent MME POOL related services.
Example two
As shown in fig. 2, the MME pool updating method of this embodiment includes the following steps:
step S201: the Embms-Gw sends a GTP request message to the MME to request the MME to report Service Area information;
step S202: after receiving the MBMS related Service message, the MME checks the field, and if the Embms-Gw requests the MME to report Service Area information, the MME reports the management Service Area information of the node; if the function is not supported, the function is automatically ignored;
step S203: the Embms-Gw receives a GTP message sent by the MME, if the GTP message carries Service Area information, the related information is stored, and an MME POOL list is automatically maintained by matching the same MME;
step S204: and using the generated data to realize the related business process of the MME POOL.
