Embodiment 2

[0057] refer to figure 2 , which shows the second embodiment of the load control method of the mobility management entity of the present application, and further includes the following steps:

[0058] Step 201, record and update the real-time status of each mobility management entity.

[0059] The base station can update the real-time status of each mobility management entity according to the actual situation. Specifically include:

[0060] If the release user equipment message "UE CONTEXT RELEASE COMMAND" sent by the mobility management entity is received, and the message carries the reason of load balancing "load balancing TAU required", then the real-time state of the mobility management entity is changed to the load pre-control state; if After receiving the overload control start message "OVERLOAD START" sent by the core network, the real-time status of the mobility management entity is changed to the load overload status; if it is determined that the load of the mobili...

Abstract

The invention provides a load control method of a mobile management entity, which is executed by a base station and comprises the following steps: receiving an initial attach request of user equipment; selecting the mobile management entity in which the user equipment is to be switched; and acquiring the real-time state of the currently selected mobile management entity, returning to the previous step if the currently selected mobile management entity is in a load pre-control state or an overload state, and switching the user equipment into the currently selected mobile management entity if the currently selected mobile management entity is in a load normal state. The invention also provides a load control device of the mobile management entity, which is used for implementing the method. According to the load control method and the load control device of the mobile management entity, the mobile management entity can be avoided being repeatedly released and switched into the user equipment, the signaling interaction waste is avoided, and the network load is reduced.

Description

technical field [0001] The present application relates to the technical field of mobile communication signal processing, in particular to a method and device for controlling the load of a mobility management entity. Background technique [0002] In a mobile network, the randomness of the user equipment (UE, User Equipment) location and the diversity of service requirements will lead to an unbalanced load distribution of the mobility management entity (MME, Mobility Management Entity), that is, some mobility management entities The load is too heavy, and even data congestion occurs, while another part of the mobility management entity is relatively idle and has a light load. When the above unbalanced load distribution occurs, the system will adopt a load balancing method to transfer some user equipments of high-load MMEs to low-load MMEs to reduce the load of high-load MMEs. By balancing the traffic distribution between mobility management entities, the utilization rate of w...
