Abstract

The embodiment of the invention provides a data exchange method and device, applied to a broadband trunking communication (B-TrunC) system, the B-TrunC system comprises a trunking core network, a trunking base station and a trunking terminal, the trunking core network comprises an eMME, and the method comprises the following steps: the eMME judges whether the trunking terminal is in an ECM IDLE state or not; when the trunking terminal is in the ECM IDLE state, the eMME establishes a dedicated bearer and a default bearer between the eMME and the trunking base station at the same time; and the eMME performs data exchange with the trunking base station by virtue of the dedicated bearer and the default bearer. The embodiment of the invention solves the problem that call delay of voice group calling is long in a scene that the eMME releases a first context connection with the trunking base station, signaling interaction messages inside the trunking core network are also reduced by one pair,and a TCF at a trunking core network side establishes the original dedicated bearer and a shared trunking dedicated bearer at the same time, so that delay is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data exchange method and a data exchange device. Background technique [0002] Most of the B-TrunC (Broadband Trunking Communication, broadband trunking communication) system retains the signaling process under the original LTE architecture. For example, the attachment process after the terminal is powered on. The B-TrunC system only adds the unique processes of the B-TrunC system under the original system architecture of LTE, such as the terminal registration process, the terminal call single call process, and the terminal group call process. This article is to solve the problems that arise in the actual group call flow. [0003] After the cluster terminal is turned on, it first performs the traditional LTE attachment process. The cluster terminal successfully attaches to the network and establishes a permanently online default bearer. Then the cluster terminal initia...
