User resource releasing method and devices

Abstract

The invention discloses a user resource releasing method and devices. The method comprises the steps that network elements establish the associated relation between an IP address of an associated entity and contextual information of UE, and the contextual information of UE comprises the IP address of the associated entity; when the network elements determine that the associated entity has faults, the correlation is inquired by utilizing the IP address of the associated entity, and the context information corresponding to the IP address is obtained; the network element releases user resources of the UE corresponding to the context information. In the user resource releasing method and the device, when the number of the UE associated to the associated entity is small, polling traversal is not needed to be conducted on the context information, the network elements can directly obtain the context information of the UE associated to the associated entity directly, the processing performance and the processing efficiency of the network elements are improved, and the processing speed of releasing the resources is accelerated. When the number of the UE associated to the associated entity is large, the network elements cannot send a large number of resource releasing messages instantly, and message jam is avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for releasing user resources. Background technique [0002] In a network including multiple network element devices, when a network element device fails, the network element device will send a fault notification message to the associated network element device, and the associated network element device will release the fault notification message after receiving the fault notification message. User resources of UE (User Equipment, user equipment) related to the network element equipment, such as: releasing resources such as context information of the UE, PDN (Packet Data Network, packet data network) information, bearer information, etc., to ensure that each associated network element Device resource consistency. [0003] Specifically, when a network element device receives a failure notification message from a faulty network element device (suc...

Problems solved by technology

[0004] When the number of UEs associated with the faulty network element device is large, the network element device needs to send a large number of resource release messages. The instantaneous large number of resource release messages will cause message congestion, increase the CPU (Central Processing Unit, central processing unit) occupancy rate, and directly Affects the processing of subsequent services, and often the CPU is too high, and the monitored process is restarted and suspended, which brings great risks to the reliability and stability of network element equipment

When the number of UEs associated with a faulty network element device is small, the network element device also needs to poll and traverse all local context information, but in fact only needs to delete a few user resources, resulting in low processing performance of the network element device. And polling through all context information also takes a long time to process
