Problems solved by technology

However, the current trunking communication system of the CDMA system cannot provide trunking services such as single call when the transmission link between the base station (BTS) and the base station controller (BSC) fails; and, in some emergency or special cases, if the operation If the provider does not configure the transmission link, it will also not be able to provide cluster services

Embodiment Construction

[0018] The following will refer to figure 2 and image 3 Embodiments of the present invention are described. figure 2 is a flowchart of a method for supporting a single call trunking service according to a second embodiment of the present invention, image 3 It is a signaling flowchart of a method for supporting a single call trunking service according to the second embodiment of the present invention.

[0019] Such as figure 2 As shown, the single call trunking service support method according to the second embodiment of the present invention includes the following steps: step S102, the base station stores the corresponding relationship between the mobile directory numbers and the international mobile subscriber identification numbers of all terminals, or each terminal stores a The corresponding relationship between the mobile directory number and the International Mobile Subscriber Identification Number of itself, when the base station detects that the link between the...

Abstract

This method includes steps: Step 102. The base station (BS) stores the corresponding relation (CR) between all terminals' mobile content number (MCN) and the international mobile user recognition number (IMURN). Or each terminal stores CR between its MCN and IMURN. When BS finds the link failure between the base station controller (BSC) and itself, BS informs the calling processing course to enterthe failure mode. Step 104. The calling terminal (CT) sends via BS the single call request to the called terminal (DT). Step 106. Receiving this request, BS directly distributes the channel resourceto CT, queries the corresponding IMURN according to DT's MCN, sends to CT the notice about the channel appointing message (CAM) and sends the paging message (PM) to DT. Step 108. CT / DT respectively receives CAM / PM and executes the single call grouped business.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for supporting a single-call trunking service. Background technique [0002] The code division multiple access (CDMA) trunking communication system can combine CDMA technology with a dedicated dispatching communication system. It adopts half-duplex communication mode and can realize fast connection, that is, it supports one-to-many group call service and also supports One-to-one private call service. [0003] figure 1 It shows the signaling flow chart of the single call service when the link is normal. Such as figure 1 As shown, when the link is normal, the base station (BTS) receives a single call initiation message from the terminal, judges that the current base station link is normal, and sends the initiation message to the network side PDS via the base station controller (BSC) (PTT Dispatching Server, note PTT: Push To Talk) processing; PDS sends a ...
