Base station controller interconnection method, device and base station controller under group call

Abstract

The invention discloses a BSC interconnection method, device and BSC under a group call. The method includes: the target side BSC receives a paging message from a trunking dispatching server PDS, wherein the paging message carries the external IP address of the calling BSC ; The BSC on the target side determines whether there is a soft handover interconnection between itself and the calling BSC according to the external IP address; if yes, the target side BSC establishes a soft handover interconnection with the calling BSC. By using the present invention, it solves the problem in the related art that in the group call, when the calling BSC and the non-calling BSC have the same identification, the target side BSC cannot correctly find the calling BSC, and then cannot establish soft handover interconnection , so that the target side BSC can accurately find the originating BSC, establish soft handover interconnection, and improve system performance.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a base station controller (Base Station Controller, abbreviated as BSC) interconnection method and device under a group call, and the BSC. Background technique [0002] The open trunking architecture (Global open Trunking architecture, referred to as GoTa) based on CDMA2000 professional trunking, consists of a cluster scheduling server (PTT Dispatching Server, referred to as PDS), a base station (Base Station, referred to as BS), and the base station includes BSC and base station Transceiver (Base Station Transceiver, referred to as BTS), terminal (Mobile Station, referred to as MS) and other equipment. [0003] Characteristics of trunking call Terminals are widely distributed, and the call establishes cell resources under multiple BSCs. Therefore, each BSC that needs to establish cell resources needs to determine the IP interconnection relationship between itself and the calli...

Problems solved by technology

[0006] The present invention provides a BSC interconnection method, device and BSC in a group call to at least solve the problem in the related art that when a group call is made and the originating BSC and the non-originating BSC have the same identity, the target side BSC cannot be correctly identified. Find the problem that the calling BSC cannot be established, and then the soft handover interconnection cannot be established
