Embodiment Construction

[0022] see Figure 1-Figure 4 , the specific implementation mode adopts the following technical scheme: the method for its realization is: the load state of MME is divided into three kinds of load states: load normal state, load pre-warning state, load overload state; The load state detection is carried out periodically to detect the change of the load state of the MME. Under different load states, the corresponding load processing is carried out in the special load pre-warning state and the load overload state, so that the load of the MME is working in a normal state.

[0023] The load control of the MME in the Pool is carried out according to the load state of each MME; the load size of each MME is detected by a periodic detection method in the MME Pool; the detection method of the MME load is: the first method The first method is to use the number of PDN connections managed by the MME as the load statistics. The second method is to use the service transmission bandwidth man...

Abstract

The invention discloses an implementation method of MME (Mobile Management Entity) load control in an LTE (Long Term Evolution) system, and relates to the technical field of MME loads. The implementation method comprises the following steps: dividing the load states of MMEs into three load states, namely, a load normal state, a load early-warning state and an overload state; and detecting the changes of the load states of the MMEs by periodically performing load state detection on the load of each MME in an MME pool, and performing corresponding load processing in different load states, particularly in the load early-warning state and the overload state in order to keep the loads of the MMEs in the normal state. Through adoption of the implementation method, load control among the MMEs in the MME pool in the LTE system can be implemented, and the control is convenient and accurate.

Description

technical field [0001] The invention relates to the technical field of MME load, in particular to a method for realizing MME load control in an LTE system. Background technique [0002] In the 3GPP 23.401 standard, it is defined that an MME Pool refers to an area composed of one or more MMEs, which is a collection of complete TA areas, and different MME Pools can be superimposed on each other. The UE does not need to change the serving MME when moving in the TA area in the MME Pool. [0003] The inter-MME load control function is for the purpose of controlling the inter-MME load within the Pool. The inter-MME load control function allows UEs that newly enter the MME Pool to be directed to an appropriate MME in the Pool according to the inter-MME load in the Pool. Therefore, eNodeBs need to control and select MMEs for access according to the load among MMEs. In the current standard, the eNodeB does not directly obtain the load technical description and requirements of the...
