Method and device for selecting mobile management entity and providing load information

Abstract

The embodiment of the invention discloses a method for selecting an attached mobile management entity for user equipment, and a method and a device for providing load information, wherein one method comprises the following steps: sending a load information request to at least one mobile management entity allowing service access; receiving the load information response returned from the at least one mobile management entity, wherein the load information response carries with the load information of the mobile management entity; and selecting the attached mobile management entity for the user equipment from the at least one mobile management entity according to the load information. The other method comprises the following steps: receiving the load information request sent by a base station; acquiring the load information; and returning the load information response to the base station according to the load information request, wherein the load information response carries with the load information. The methods and the device can effectively use resources and ensure the balance of MME loads in an MME pool.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for selecting a mobile management entity to attach to a user equipment, a method and a device for providing load information. Background technique [0002] In the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) Long Term Evolution (LTE, Long Term Evolution) / Core Network Evolution (SAE, System Architecture Evolution) system, the base station (eNodeB) directly communicates with the core network equipment through the S1 link connection, generally the core network equipment includes a Mobility Management Entity (MME, Mobility Management Entity) / Serving Gateway (S-GW, Serving Gateway). [0003] In order to improve the reliability of the link between the eNodeB and the core network equipment, the core network equipment MME / S-GW can be formed into a pool (POOL) for load balancing and redundant backup. [0004] For SAE, when a POOL i...

Problems solved by technology

[0006] There are many types of UE services, such as voice, video, web browsing, mobile TV, and data download. Different services occupy different system resources, and the eNodeB only controls the proportion of UEs attached to different MMEs according to the capabilities of the MME. Therefore, the services used by UEs connected to a certain MME occupy far more system resources than other MMEs. As a result, although the ratio of the number of UEs attached to different MMEs in the MME pool is balanced, the actual load on different MMEs Unbalanced, unable to make rational use of resources
