Method and device for handling service tunnel exception

Abstract

The present application relates to the field of communications, and in particular to a method and device for processing abnormalities in service tunnels, which are used to avoid excessive occupation of network resources when detecting abnormalities in service tunnels on the user plane. The method is: when the base station determines that the service tunnel of the user plane is abnormal, instructs the core network to modify the path of the service tunnel through control plane signaling, and after determining that the modification is successful, uses the service tunnel based on the modified path Continue to perform service data transmission with the core network. In this way, the existing 3GPPR15 protocol has been further improved, so that the core network side can be informed of the abnormality of the user plane service plane tunnel in time and perform corresponding processing operations, thereby ensuring the relevant bearer and communication of the terminal on the base station side and the core network side. The state consistency of resources effectively improves the available resources of the core network, and at the same time prevents terminals from excessively occupying network resources.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a method and device for processing abnormalities in service tunnels. Background technique [0002] In the mobile communication system, the control plane and the user plane are separated. Before the terminal performs service transmission, it needs to establish a service tunnel with the network side through the control plane signaling. After the service tunnel is successfully established, the service transmission of the user plane is carried out; Wherein, during the signaling interaction process, user plane Internet Protocol (Internet Protocol, IP) address information used for service transmission is exchanged for establishing a service tunnel. [0003] It can be seen that whether the service tunnel can be established normally is the key factor related to whether the service transmission can be carried out correctly. Therefore, it is necessary for network elements to coo...

Problems solved by technology

[0006] The core network side cannot process the relevant bearer and resources of the terminal in a timely manner, resulting in inconsistent bearer status of the terminal on the base station side and the core network side, which in turn causes excessive occupation of network resources, wastes storage space, and further increases the number of interfaces The signaling interaction process affects the user experience
