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.
Figure 1 shows that the group system core network architecture schematic diagram of prior art.The information of opening an account that has the user in the attaching position register (HLR) 101, at least comprise user's international mobile subscriber identity (IMSI) and affiliated group ID tabulation in this information, each group calling user can belong to one or more group simultaneously, but at most can not be above 50.Visited Location Registor (VLR) 103 is used for writing down the user of present position-region, it duplicates this user's IMSI and affiliated group ID from HLR 101, 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.A specific VGCS is in charge of and is safeguarded to anchor mobile switch (Anchor MSC) 104, it links to each other with gateway mobile switch (GMSC) 102 logics, directly link to each other with GCR105, GMSC 102 is used to connect external network, GCR 105 is used to store the group calling attribute information, at least comprise group ID and group call region in this attribute information, group ID and group call region lump together and are called group call reference.
When group call region jumped a plurality of MSC, interior all MSC except that anchor MSC 104 of group were relaying mobile switch (Relay MSC) 107, are the tree-shaped relation of one-to-many between anchor MSC 104 and the relay MSC 107.With also comprise dispatcher tabulation, the relay MSC relevant in the group calling attribute information among the GCR 105 that anchor MSC104 links to each other and tabulate and the directly actuated cell list of anchor MSC with group call reference; With also comprise the cell list that the anchor MSC address relevant with group call reference and this relay MSC are controlled in the group calling attribute information among the GCR 108 that relay MSC 107 links to each other.
Anchor MSC 104 receives when request is initiated in group calling, attribute information to GCR 105 these groups of inquiry that it connected, the cell list under thereby dispatcher's tabulation, relay MSC tabulation and this MSC of obtaining this group control, afterwards, call out dispatcher and relay MSC 107 in this group, and set up group-calling channel in the sub-district under this anchor MSC104 control, there is group calling to initiate by user in the NCH group of notifications of each sub-district, and indicates its group-calling channel so that the user monitors in the group.
After relay MSC 107 is received the group calling request of anchor MSC 104, inquire about the cell list of this group to the GCR108 that is connected, in the sub-district, set up group-calling channel, have group calling to initiate, and indicate its group-calling channel so that the user monitors in the group by user in the NCH group of notifications.
The defective of above-mentioned group calling mode is: the attribute information of the group call member among the GCR as dispatcher's tabulation, anchor MSC address, relay MSC address, lane place etc., all is the static information of this group member when opening an account.After certain the group calling user in a certain group enters a certain reposition district, when having group calling to initiate, the log-on message that dispatching desk only obtains this group calling user when opening an account, and it is also unclear for the current position distribution situation of group calling user, even do not know current have how many group calling users the net in, thereby present group-calling service can not satisfy dispatches requirement at any time reliably.
