[0003] However, due to the limited overall resources, each terminal can only be allocated a small number of call bearer resources. In the case of resource shortage, if these pre-allocated call bearer resources are occupied by other According to the definition of the current protocol, it is necessary to release the call currently occupying the pre-allocated call bearer resources before establishing a higher priority call, which will increase the establishment delay of the high priority call

Abstract

The present invention discloses a method and device for creating a session. The method is applied to the network side and includes: creating a pre-established session channel between a calling terminal and a called terminal; receiving a high-priority call request from the calling terminal, and unbinding The pre-established session channel of the calling terminal; using the pre-established session channel to create a high-priority session of the calling terminal. Use the current pre-established session channel to create a high-priority call, without waiting for the existing call to be unbound from the pre-established session before re-establishing the session channel, that is, to replace the original call with a high-priority call to obtain an occupied pre-allocated call Bearer resources realize the purpose of quickly establishing high-priority calls.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for establishing a session. Background technique [0002] 3GPP has developed a standard protocol for trunking dispatching services in the fields of public security, which includes pre-established calls. Since pre-established calls are pre-allocated call bearer resources, pre-established calls can reduce call delay. At the same time, in the case of resource shortage Ensure that high-priority calls can be established successfully. [0003] However, due to the limited overall resources, each terminal can only be allocated a small number of call bearer resources. In the case of resource shortage, if these pre-allocated call bearer resources are occupied by other According to the definition of the current protocol, it is necessary to release the call currently occupying the pre-allocated call bearer resources before establishing a call with a higher ...
