Description
Technical field
The present invention relates to the group calling technology of wireless trunking communication system, particularly a kind of wireless trunking communication system user initiates the method for group calling.
Background technology
Wireless trunking communication system, can be called for short group system, be a kind of less expensive of growing up in recent years, command dispatching and communication system more flexibly, be 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.
It is voice group call service (VGCS) that group system provides the most basic business.VGCS allows the user to be established to belong to one group of user's of a certain given service area and group ID calling, the professional employing semiduplex mode that provides, any member can become the speaker during the calling, but arbitrary moment only allow a speaker, other members are the hearer.Service area can be made up of some sub-districts that belong to same MSC or different MS C, and each related cell has a group-calling channel during calling, and wherein up link is only used for current talker, and just current talker is the group emission mode; All hearers keep the marquis on down link, and just all hearers are group receive mode; The notification message of group-calling channel configuration is broadcasted on notification channel (NCH) notification channel.Because same community user is shared a down channel, thereby has saved Radio Resource greatly.
The structure of group system core net is referring to Fig. 1, and Fig. 1 is a prior art group system core network architecture schematic diagram.Wherein, have user profile in the attaching position register (HLR) 102, comprise that the group ID under user's international mobile subscriber identity (IMSI), the user tabulates, a common user can belong to 50 groups at most.
Gateway mobile switch (GMSC) 103 links to each other with external network 101, and GMSC also links to each other with anchor mobile switch (Anchor MSC) 103.
Anchor MSC103 is in charge of and safeguards a specific VGCS.
Relay MSC (Relay MSC) the 107th, when group call region jumps a plurality of MSC, all MSC except that anchor MSC.It between anchor MSC105 and the relay MSC 107 the tree-shaped relation of one-to-many.
Visited Location Registor (VLR) 104 has the ID tabulation of organizing under user IMSI, the user.When the user roamed, these information copied from HLR102 and come.VLR 104 duplicates this user's IMSI and affiliated group ID from HLR 102, for the user who enters this lane place distributes a temporarily moved subscriber identification number (TMSI), the user who leaves this lane place for roaming discharges its information, for shutdown or fail user that the position upgrades for a long time this state of user is set is that IMSI separates, VLR distinguishes with Group Call Register (GCR) with MSC in its region and directly links to each other.
Comprised group ID and group call region in the Group Call Register (GCR) 106, group call region lumps together with group ID and is called group call reference.Wherein with among the continuous GCR106 of anchor MSC105 comprised the dispatcher tabulation relevant with group call reference, relay MSC tabulation, the directly actuated cell list of anchor MSC, the dispatcher is the group calling user that the scheduling qualification is arranged.The GCR106 that links to each other with relay MSC 107 has then comprised the anchor MSC address relevant with this group call reference, the cell list that this relay MSC is controlled.
In the group system of reality, VLR, the GCR that MSC is connected with this MSC can be made in the same physical entity, has corresponding physical connection relation and logic connecting relation between them.
In the present group system, each group comprises a group id ID and group call region, and wherein group call region is defined as the gang sub-district, and these information all are the fix informations that the user stores in HLR and SIM card when opening an account.And the group calling attribute among the GCR, as dispatcher's tabulation, anchor MSC address, relay MSC address, the cell list under this MSC control, priority etc. are determined when also just the user opens an account.Above-mentioned information almost completely is static, and at certain particular group, network can not write down its active user's roaming active situation.
Referring to Fig. 2, Fig. 2 is prior art group calling start flow figure.This flow process may further comprise the steps:
Step 201, group calling user or dispatcher send the group calling request to anchor MSC.
Step 202, anchor MSC sends the attribute that the user place group of group calling is initiated in inquiry group attribute message (VGCS ATTRIBUTE REQUSST) inquiry to coupled GCR (GCR-A).
Step 203, GCR-A returns group property response (VGCS ATTRIBUTERESPONSE) message to anchor MSC, and comprising the anchor MSC control group call cell tabulation of determining when opening an account down, relay MSC tabulation and dispatcher tabulate.
Step 204 after anchor MSC receives property response message, sends group calling according to the relay MSC tabulation to all relay MSC and sets up message, simultaneously execution in step 205.
Step 205, anchor MSC obtains the group call cell tabulation from the property response message of receiving, and subordinate's base station sub-system (BSS) sends and sets up group-calling channel (VGCS ASSIGNMENTREQUEST) message in cell list.Simultaneously, execution in step 206.
Step 206, anchor MSC will send to connect and set up message to all dispatchers.
Step 207, the dispatcher returns to connect and sets up success message.
Step 208 after each BSS receives and sets up group-calling channel message in the group call region sub-district of anchor MSC control, is set up group-calling channel; And there is group calling to initiate by user in the NCH group of notifications of each sub-district.
Step 209, BSS returns group-calling channel to anchor MSC and sets up successfully (VGCS ASSIGNMENTCOMPLETE) message; And there is group calling to initiate by user in the NCH group of notifications.
Step 210 after each relay MSC receives that message is set up in group calling, sends the attribute that the user place group of group calling is initiated in the inquiry of inquiry group attribute message to coupled GCR (GCR-R).
Step 211, GCR-R returns group property response message to relay MSC, comprising the relay MSC control group call cell down determined when opening an account tabulate.
Step 212, relay MSC obtain the group call cell tabulation from the property response message of receiving, subordinate's BSS sends and sets up group-calling channel message in cell list.
Step 213 after each BSS receives and sets up group-calling channel message in the group call region sub-district of relay MSC control, is set up group-calling channel.
Step 214, BSS returns group-calling channel to relay MSC and sets up success message; And there is group calling to initiate by user in the NCH group of notifications.
After step 215, relay MSC receive that group-calling channel is set up successful information, send group calling to anchor MSC and set up successfully (CONNECT) message.
From above-mentioned flow process as can be seen, no matter be anchor MSC, or relay MSC, when setting up group-calling channel, not at group calling user itself, but inquiry GCR obtains the tabulation of group call region corresponding district, sets up group-calling channel again in all these sub-districts.
This method is used for some specific group calling, comparatively wastes Radio Resource.Police's criminal investigation group in city for example, over the long term, its scope of activities is bigger, covers whole city usually, and promptly group call region is bigger.But at each special time period, in some day or several hrs, its group in the user one more among a small circle in the activity.Do not have the user in other scopes, just there is no need to set up group-calling channel yet.But existing method can only paging in whole urban area, and sets up corresponding group-calling channel, thereby causes waste of radio resources.
