Description
Technical field
The present invention relates to the application technology of wireless trunking communication system, particularly a kind of the wireless trunking communication system user is carried out mobility management method.
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.VLR104 duplicates this user's IMSI and affiliated group ID from HLR102, 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 the dispatcher tabulation relevant, relay MSC tabulation, the directly actuated cell list of anchor MSC have been comprised with group call reference.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.
Receive that anchor MSC105 inquired about this group attribute to the GCR106 that is connected when request was initiated in group calling.Obtain the cell list under dispatcher's tabulation, relay MSC tabulation and this MSC control.And then call scheduling person, group-calling channel is set up in calling relay MSC 107 and the sub-district under this MSC control, has group calling to initiate by user in the NCH group of notifications of each sub-district, and indicates its group-calling channel so that user's monitoring in the group.
After relay MSC 107 is received the group calling request of anchor MSC105,, in these sub-districts, set up group-calling channel, have group calling to initiate by user in the NCH group of notifications, and indicate its group-calling channel so that the user monitors in the group to the GCR106 inquiry cell list that is connected.
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, does not promptly carry out mobile management for the user of certain particular group.
Like this, no matter be anchor MSC, or relay MSC, before group calling is initiated, all can not carry out any maintenance to particular group.When group calling is initiated and is set up group-calling channel, also can not be at group calling user itself, tabulate and just inquire about the respective cell that GCR obtains group call region, the group user of each sub-district initiates group calling and sets up group-calling channel in this cell list.And the cell list among the GCR is set up when the user opens an account, thus network can't the acquisition group in User Activity situation at present, how many users even do not know has at present in net.Along with the continuous expansion with user scope of developing rapidly of group system, thisly can't satisfy more and more higher dispatching requirement to group user management method blindly.
