Description
Technical field
The present invention relates to Digital Clustering wireless communication system group call business, the recognition methods of speaker in particularly a kind of group call.
Background technology
The Digital Clustering wireless communication system is 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 intercommunicating needs of constituent parts.
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, each related cell has a group-calling channel (comprising the uplink and downlink link) during calling, 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, has improved spectrum utilization efficiency.
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 ISDN number (MSISDN), the tabulation of the group ID under the user of user's international mobile subscriber identity (IMSI), travelling carriage, 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, MSISDN, the user.When the user roamed, these information copied from HLR102 and come.VLR104 duplicates this user's IMSI, MSISDN 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.
By above-mentioned group-calling process as seen, the ID of group set up to call out because group call is based on, thus during calling out network side only with group calling ID as the sign of calling out, do not understand the state of living in of each user in the group.Even having seized up channel, certain user becomes the talker, though other users in the group can hear speech content, and do not know talker's identity, because network side does not send to all hearers with talker's identify label.
In the group call operation flow that GSM Phase2+ describes, do not provide the method and the corresponding message support that speaker's identify label are sent to other users.Referring to Fig. 2, Fig. 2 is a prior art group call uplink lchannel preempting flow process, and this flow process may further comprise the steps:
Step 1, this message of base station sub-system (BSS) periodically send on group-calling channel FACCH, the up channel idle message (UPLINK_FREE) of indication current up channel free time of mobile phone.
Step 2, when travelling carriage (MS) will be seized up channel, send request to BSS and take up channel message (UPLINK_ACCESS), this message is by the up transmission of group-calling channel, indication user request takies up channel, carries reason and the random reference information of inserting.
Step 3, BSS sends uplink requests (UPLINK_REQUEST) to anchor MSC (MSC_A), and each BSS only need send one.
Step 4, BSS returns the up response message (VGCS_UPLINK_GRANT) that takies by after the preemption decision to MS, and BSS is in order to save time here, do not wait for the affirmation upstream request message (UPLINK_REQ_ACK) that anchor MSC sends, and directly return VGCS_UPLINK_GRANT to MS.This message response is up to take request, comprises that the synchronizing information (physical message) of travelling carriage and network and up access seize resolution (random reference).After MS receives this message, can begin speech.
Step 5, BSS is in the busy message (UPLINK_BUSY) of the descending transmission up channel of group-calling channel, and the current up channels of MS all in the notifying cell is busy.
Step 6, the MS that receives VGCS_UPLINK_GRANT confirms whether oneself robs and accounts for up channel according to whether the random reference information that comprises in this message is identical with the random reference information that oneself sends, and to BSS transmission SAMB (L3 MSG) message, this message is layer two link establishment and layer three message.
Step 7, anchor MSC sends UPLINK_REQ_ACK to BSS after selecting suitable speaker.Uply take success, anchor MSC also will send up (UPLINK_SEIZED) message that is hunted down and give other BSS, notify up busy.
Step 8, the MS that BSS seizes up channel to request sends UA (L3 MSG) message, and this message is that layer two link establishment are confirmed and layer 3 comprises the response message of fighting for resolution information.
Step 9 has taken up channel by other BSS if anchor MSC learns this moment, and then anchor MSC is to sending refusal upstream request message (UPLINK_REJECT) to BSS refusal upstream request, execution in step 10 back process ends.
Step 10, BSS starts up release flow process, and the MS that seizes up channel to request sends up channel release message (UPLINK_REL).
Step 11, it is busy that other MS of BSS sends UPLINK_BUSY message informing up channel.
Step 12, BSS sends up channel to anchor MSC and seizes success message (BSSUPLINK_REQ_CNF).
Step 13, anchor MSC sends to the occupied message of all relay MSC (MSC_R) data feedback channel (FORWARD_GROUP_CALL_SIGN), is used for notifying up occupied.
In this flow process, network side is not known the IMSISDN number of the travelling carriage of seizing up channel (speaker), does not send to other users certainly yet.Which user that is to say that the user can not know current speech by MS is.And for being accustomed to point to point call and providing seem shortcoming to some extent of the user of caller number identification, Presentation Function, this point.
Summary of the invention
