Description
Technical field
The present invention relates to the wireless trunking communication system technical field, be meant a kind of method that discharges open channel area resource especially.
Background technology
Wireless trunking communication system hereinafter to be referred as group system, is a kind of economy of growing up in recent years, command dispatching and communication system more flexibly.This system is widely used in units such as government bodies, energy traffic, airport harbour, industrial and mining enterprises, fire-fighting police, water conservancy and military affairs, to satisfy the needs of constituent parts intercommunication.
The basic service that group system provides is voice group call service (VGCS).VGCS allows to belong to set up between one group of user of a certain predefined group call region and group id (ID) and calls out.This business adopts semiduplex mode, and any member during the calling in a group can become the speaker, but arbitrary moment only allow a speaker, other members are the hearer.Predefined group call region is made up of some sub-districts that belong to same mobile switch (MSC) or different MS C, each related cell has a group-calling channel during calling, and current talker uses up link, promptly organizes emission mode, all hearers use down link, i.e. group receive mode.The notification message of group-calling channel configuration is gone up broadcasting at notification channel (NCH).Because same community user is shared a down channel, thereby use VGCS and saved Radio Resource greatly.
At some specific user, for example patrol is alert, in order to respond various accidents fast, group system has also been set up special channel for it in each sub-district, saved the process that group calling is set up, thereby realized that really once by leading to, this special channel is open channel.Generally, the activationary time of open channel is longer, is equivalent to this channel and is used by certain group leader's time charter.
When using VGCS or Voice Broadcast Service (VBS), need foundation, resource assignation and dispose procedure through group calling.The foundation of so-called group calling is promptly set up a group calling by call establishment; So-called resource assignation is meant, for organizing the group-calling channel resource of each cell allocation special use in the zone; So-called dispose procedure is meant, discharges the shared resource of whole group calling and removes the shared channel of group calling.
The process of the whole group call resource of existing release as shown in Figure 1.Realize being connected by SCCP (SCCP) between MSC and the baseband subsystems (BSS), BSS sends control signaling on NCH travelling carriage (MS), on descending group-calling channel to MS broadcasting speech business.After a group-calling process finished, MSC sent the message of removing control (CLEAR COMMAND) to BSS, and BSS discharges the shared Radio Resource of this group calling with indication.
After BSS receives CLEAR COMMAND message, start the protection timer, and start the clear program on the wave point, discharge group-calling channel in all sub-districts relevant with this group calling.Simultaneously, BSS is changed to the land circuit of assignment idle condition and returns the message that (CLEARCOMPLETE) finished in removing to MSC.When MSC returns CLEAR COMPLETE message, do not need to wait for that wireless channel discharges finishes or protect timer expiry at BSS.After MSC receives CLEARCOMPLETE message, discharge ground resource.
The process of existing multicall channel releasing as shown in Figure 2.The BSS of network side inserts the access idle message (UPLINK FREE) of asking cell by carrying up link, and the current listening user of VGCS that whether exists in inquiry sub-district is promptly answered travelling carriage.Insert request if there is travelling carriage to respond this up link, then network side is known the group calling user in this sub-district, and keeps the up-downgoing group-calling channel for it; As do not have travelling carriage to respond this up link access request, then network side will be removed the up-downgoing group-calling channel resource of this sub-district.But the operation of this removing channel resource only is the group-calling channel of deletion air interface because this moment the broadcast message of old this group calling still on NCH, exist in this sub-district in order to indicate this group calling.In case when having new group calling user to enter this sub-district, can apply for setting up this group-calling channel again by up access procedure.
For existing common group-calling service, its group call region pre-defined before group call establishment process, can't change in group-calling process.Promptly for certain group-calling service, itself or safeguard the resource of all sub-districts in the whole group call region all the time, perhaps delete the resource of all sub-districts in the whole group call region simultaneously.
Prior art does not define corresponding handling process at open channel, only is to make it continue to use the handling process of existing common group calling.Thereby when handling the open channel business, there is following defective:
Owing to discharge the processing of channel in the existing group calling handling process, just delete the group-calling channel of air interface, and BSS also continues on NCH broadcasting group calling message, thereby can not realize the independent release of certain or certain several local resources, promptly can not dynamically adjust the calling area of open channel.And the common activationary time of open channel is longer, if can not realize in the open channel the independent release to certain or certain several local resources, will cause the serious wasting of resources.
