Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
Embodiment one
The present embodiment is applied to multicenter group system group-network construction shown in Figure 1, is provided with the group status register in the network, is used for storing the anchor exchanger information of current group calling state and current group calling.The group status register can have one or more, but same group state information can only be stored in the memory, and switch identifies to obtain to organize the route of status register by sets of numbers.Each switch storage sets positional information in the network and current group calling state, the group positional information comprises group membership place cell information and other exchanger information of group membership place under this switch.
The group member is distributed under a plurality of switches, and no matter the user initiates group calling under which switch, all need to the group status register anchor switch is set, the group calling control flow of the present embodiment as shown in Figure 2, this flow process comprises:
Step 201: local switch is initiated group calling as the anchor switch and is set up request
Local switch is received user's group calling foundation request, can local switch carry out according to group calling authority judgement group calling, if think that this calling is feasible, local switch is according to the repeater exchanger tabulation of group sign inquiry group positional information, if comprise repeater exchanger, then send group calling as the anchor switch to repeater exchanger and set up request, and the group paging residential quarter under local switch sends the group calling beep-page message, if comprise dispatching desk and wire user in the group, then send the call page request to dispatching desk and wire user.
Step 202: repeater exchanger is replied group calling and is set up response
After repeater exchanger receives that request is set up in the group calling of anchor switch, reply group calling for the anchor switch and set up response, at first judge the group calling state of self record, if the group calling state is for busy, illustrate and had group calling in the network, then reply group calling to local switch and set up unsuccessfully, local switch is received that group calling is set up and is unsuccessfully discharged at once current group calling, and adds in the already present group calling; If the group calling state is idle, then repeater exchanger record group state is busy, and record anchor switch identification.
Step 203: repeater exchanger is replied group calling foundation and is finished
Session between repeater exchanger foundation and the anchor switch, the terminal under the residential quarter in the group is distributed shared channel under this repeater exchanger of paging, sets up then for anchor switch answer group calling and finishes, and repeater exchanger enters in the group calling, link between monitoring and the anchor switch; If link is unusual, then repeater exchanger discharges group calling.
Step 204: carry out with step 1 is concurrent, the anchor switch arranges request to group status register transmission group state, the group calling state is set for doing and the anchor exchanger information being set.
Step 205: group status register answer group state arranges response
Group status register inquiry group calling state, if original state is for busy, and the anchor switch is not this anchor switch, illustrate and had group calling in the network, then to local switch answer group state setup failed, local switch receives that the setup failed request discharges current group calling at once, and adds in the already present group calling; If originally the group calling state is idle, then organize status register group state and arrange successfully, and record anchor exchanger information.
Step 206: the current speaker number of anchor switch notice repeater exchanger is identified, and processes the right to apply for words of group call member under the repeater exchanger, carries out calling out in the calling talk control.In paging, the anchor switch is responsible for setting up the link that this anchor switch is directly controlled residential quarter, repeater exchanger and dispatching desk.
As seen from the above description, the present invention has following characteristics: 1, owing to adopting the distributed call management method, implement group calling by caller place switch and set up control, each switch can independently become to call out control, rather than employing group centralized control method, the anchor switch need not to carry out the group identification code route analysis, and does not need group calling is routed to predefined mooring anchor switch, thereby Signalling exchange between the switch when reducing call setup can quicker access group calling.2, switch repeater exchanger tabulation in the acquisition group before group calling makes a call can be initiated group calling to the interior switch of tabulation at once when then group calling is initiated and set up, and does not need the Group Call Register inquiry.3, anchor switch process and group call establishment process are set and carry out simultaneously, can guarantee preferentially that group calling sets up speed.4, employing group status register carries out group state storage, and the group state is stored in unique control point in network, can avoid because distributed group calling, causes that the user initiates group calling simultaneously under a plurality of centers, and the user adds the not situation of concentric group calling.
In order to ensure the reliability of group state, the group status register is also kept the group calling state, group calling state heartbeat between monitoring group status register and the anchor switch, if it is unusual to detect heartbeat, then organize status register group calling state and be set to the free time, the anchor switch arranges the anchor exchanger information to the group status register again behind link-recovery.After group calling is set up, the anchor switch also monitor and repeater exchanger between link, if link re-establishment, the anchor switch will be rebuild in the repeater exchanger adding group calling of link.
Embodiment two
On the basis of embodiment one, when the group membership switches in group-calling process, if target switch has recorded the anchor exchanger information, then directly reply handover success and allocated channel to the group membership, otherwise target switch is to group status register inquiry anchor exchanger information, the again calling between foundation and the anchor switch.
The present embodiment two is with the example that switches to of the side of answering in the group calling, and as shown in Figure 3, its switching flow is as follows:
Step 301: target switch sends the anchor query requests
The user switches to target switch in group-calling process, if target switch is in group calling, be that target switch has been stored current anchor switch, change descending new the answering of sharing over to then can directly for user assignment DSCH Downlink Shared Channel, user for the side of answering user.If target switch is switch outside the group call region, then target switch sends the anchor query requests to the group status register.
Step 302: the group status register sends to target switch with current anchor exchanger information.
Step 303: target switch is switched to the request of anchor switch, sets up the group calling session.
Step 304: the anchor switch judges whether the user possesses the outer authority of the group call region of switching to, if allow, then replys to switch to target switch and finishes.
Step 305: target switch is to the terminal distribution DSCH Downlink Shared Channel, and the user changes DSCH Downlink Shared Channel over to and answers.
According to the above description as seen owing to possessing the group status register in the network, the user switch to group call region outer switching center after, can obtain group calling state and group anchor information by the group status register, thereby set up and organize handoff procedure between the anchor.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
