Embodiment 1

[0096] Fig. 5 shows a signaling flow chart of the group call preemption method in this embodiment. In Fig. 5, both the speaking party and the listening party are mobile stations (MS), wherein MS1 ​​is the original speaking party, MS2 is the new speaking party, and MSn represents other mobile stations except MS1 and MS2 in the cell under the jurisdiction of the BSS. In addition, it is assumed that the priority of the original speaker MS1 is normal, and the priority of the new speaker MS2 is higher than that of the original speaker, for example: urgent.

[0097] As shown in Figure 5, the group call preemption method in this embodiment includes the following steps:

[0098] Step 501. The original speaker MS1 is speaking to all the listeners in the group.

[0099] At this time, the listening parties in the group are the MSs in the group except the original speaking party MS1, namely MS2 and MSn.

[0100] Steps 502 to 504. When the new speaker MS2 has a higher priority than the ori...

Embodiment 2

[0126] In this embodiment, an SCCP connection is pre-established to distinguish between two talking parties that exist at the same time. The difference between this method and the process shown in FIG. 5 lies in that the time for establishing the SCCP connection is different. Specifically, in this embodiment, an SCCP connection is pre-established between the BSS and the AMSC. When a new speaker MS2 preempts the uplink channel in a group call, the new speaker occupies the pre-established SCCP connection to send messages through the A interface. In other words, the SCCP link management control module in the BSS and AMSC cooperates with the A interface message sending module to pre-allocate the SCCP connection number and establish the SCCP connection.

[0127] FIG. 6 shows a flowchart of a method for group call preemption in this embodiment.

[0128] In steps 601-603, the original talking party MS1 is speaking to all the listening parties in the group; when the new talking party...

Abstract

The method comprises: a) when the priority of speak side newly participating the session is higher than the one of the original speaking side, the newly participating side interacts with the base station sub-system (BBS) to request the occupation of uplink channel, and the BBS interacts with the anchor mobile service center (AMSC) to establish the signaling connection control part (SCCP) connection corresponding to the newly participating side; b)BBS indicates that the newly participating side makes uplink occupation to AMSC through the SCCP connection corresponding to the newly participating side, and releases the original speak side.

Description

technical field [0001] The invention relates to a group call technology in a cluster wireless communication system, in particular to a group call preemption method and system. Background technique [0002] The cluster wireless communication system, usually referred to as the cluster system for short, is a relatively economical and flexible command and dispatch communication system developed in recent years. It is widely used in government agencies, energy transportation, airport terminals, industrial and mining enterprises, fire police, Water conservancy and military units, to meet the needs of internal communication of each unit. [0003] The most basic service provided by the trunking system is the voice group call service (VGCS). VGCS allows a user to establish calls with multiple users belonging to a given service area and cluster group with the same group ID (ID), where the service area consists of several mobile services switching centers (MSCs) belonging to the same ...
