Embodiment Construction

[0043] NLN mainly includes notification messages on the NCH channel, paging messages on the PCH channel, and system messages on the SACCH channel 6. The management of system messages on the SACCH channel is centralized in the BSC, while the scheduling of messages on the NCH channel and PCH channel And management is realized jointly by BTS and BSC. Therefore, the management of NLN must be done jointly by BSC and BTS.

[0044] Since the NLN on the SACCH channel needs to be coordinated with the NLN on the PCH channel and the NCH channel, the basic management of the NLN is implemented by the BSC. The BSC uses the notification message to notify the base station to start or stop a VBS or VGCS service. The message contains The group call reference number corresponding to the VBS or VGCS service and the NLN value calculated by the BSC using a modulo 4 counter. Every time the BSC initiates a new VBS or VGCS call, the NLN value will increase by 1 modulo 4, and the BSC will carry the ne...

Abstract

The method includes steps: base station BTS records and stores notification list number (NLN) sent at latest one on notification channel NCH and page channel PCH; within one dispatching cycle of NCH / PCH channel, if receiving direction of new notification message of initiating new voice broadcast service (VBS) and / or voice group call service (VGCS) sent from base station controller (BSC), then BTS carries NLN different from the stored NLN when carrying out dispatch next time on NCH / PCH channel; after receiving NLN different from the previous NLN, mobile station monitors NCH channel. The invention also discloses equipment and system corresponding to the method. The effective simplified mechanism in the invention for monitoring NCH reduces load received by mobile station effectively, and ensures mobile station can obtains message in time when new VBS or VGCS is initiated at network side.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, device and system for realizing a channel monitoring mechanism. Background technique [0002] Mobile stations that support Voice Broadcast Service (Voice Broadcast Service, VBS) and Voice Group Call Service (VoiceGroup Call Service, VGCS) will read the notification channel (NotifyChannel, NCH) to receive notification messages in idle mode, and the NCH channel is dedicated to Send notification messages, these notification messages contain the group call reference number corresponding to the currently ongoing VBS or VGCS service, and the mobile station that supports VBS and / or VGCS service records the VBS and / or VGCS group to which it belongs in its SIM card Corresponding group call reference number, when receiving the notification message, compare whether the group call reference number contained in these messages exists in the group call reference number list recor...
