Method and device for overload treatment

Abstract

The invention discloses a method for overload treatment. When a core network node is overloaded, user equipment UE in an overlapped area is transferred to other resource pools sharing an overlapped area with the overloaded core network node. The method applied can quickly reduce the load of the overloaded equipment, equalize the network resources and improve the user experience.

Description

technical field [0001] The invention relates to the technology of balancing network resources, in particular to a method and device for overload processing. Background technique [0002] In the process of existing user equipment UE accessing the network or users using the network, it is very important to allocate network resources reasonably due to the existence of a large number of UE users. Existing communication networks can distribute network resources in a balanced manner through load balancing, load rebalancing, and overload handling. [0003] Taking the SAE system as an example, the SAE system can realize the allocation of network resources through various methods such as load balancing, load rebalancing, and overload handling. Wherein, the load balancing refers to when the user equipment UE initially accesses or the UE just enters a certain resource pool (Pool), where the Pool refers to an area in which the user equipment UE moves without changing the serving MME. ...

Problems solved by technology

[0004] If an MME is overloaded, if only overload processing is performed, it can only guarantee that the MME will not further increase its load, but it will not significantly reduce the load. The UE releases the connection or moves to another Pool to gradually reduce the load, and because the MME is overloaded for a long time, the eNodeB will not allow the UE to access the MME for a long time, and because the MMEs in the entire Pool are actually overloaded, the UEs will not be able to access the network for a long time, resulting in a decline in user satisfaction and the network will not be able to perform new communications

[0005] Through the existing technology described by taking the SAE system as an example, the inventor found that the existing overload processing can only prevent further load aggravation by preventing new users from accessing, but cannot quickly reduce the load of overloaded devices, and cannot balance network resources in time. Therefore, the probability of users being rejected by the network or unable to access the network is high, which affects user experience
