Embodiment
The embodiment of the invention is by carrying the precedence information of terminal called, to guarantee normally continuing of high priority terminal call in the message that issues at the core net control appliance.Wherein, described message is used for BSC to be handled accordingly according to described priority information, promptly seizes the sdcch that the low priority terminal takies, use for the high priority terminal,
With reference to figure 1, realize the schematic flow sheet of called terminal succeed method for inventive embodiments is a kind of, comprising:
Step 102: the core net control appliance disposes the precedence information of described terminal called according to the priority of terminal called in sending to article one message of terminal called;
Among this method embodiment, the core net control appliance can be (the MSC of mobile switching centre, MobileSwitching Center) core net control appliance such as, the core net control appliance can be done corresponding configuration in Paging message, i.e. the different priority parameters of configuration in Paging message.Paging message is a message of GSM standard agreement regulation, and the core net control appliance that is terminal when called sends to article one message of terminal.
When specific implementation, can directly carry the precedence information of terminal called by the channel needed cell in the Paging message, also can carry the precedence information of terminal called by the emlpp cell in the Paging message.
When the direct precedence information by the configuration of the channel needed cell in Paging message terminal called, the core net control appliance can be according to the different parameters that comprises in the channel needed cell: Anychannel, SDCCH, SDCCH, TCH/F, TCH/H or TCH/F represent different priority.
In this case, can be according to pure signaling channel flow process and call flow different, carry out different priority configuration modes, for example
(1), for pure signaling channel flow process;
When terminal called is ordinary terminal, the channel needed cell in the paging message is configured to any channel;
When terminal called is the high priority terminal, when also being first terminal, the channelneeded cell in the paging message is configured to sdcch.
Wherein, as a kind of concrete implementation, described pure signaling channel flow process can be short message idiographic flows such as (sms, short message service), and the embodiment of the invention does not limit this.
(2) for call flow;
When terminal called is ordinary terminal, with the configuration of the channel needed cell in paging message any channel;
When terminal called is the high priority terminal, the channel needed cell in the paging message is configured to tch/f or tch/h;
When disposing the precedence information of terminal called by the emlpp cell in the Paging message, the access device that needs described terminal called correspondence, as BSC etc., from the emlpp cell, obtain the precedence information of terminal called, and this precedence information is filled in the channel needed cell of Paging message.The expression mode of described channel needed cell medium priority does not repeat them here with above-mentioned directly to carry the mode of precedence information of terminal called by the channel needed cell in the Paging message identical.
Need to prove, can carry the parameter of call priority at the emlpp cell, it is the parameter that is used for explaining priority in the agreement, the core net control appliance is represented the precedence information of terminal called by callpriority, after BSC receives described Paging message, know the precedence information of terminal called according to the priority of call priority parameter representative.BSC sends to terminal called with described Paging message disposed precedence information in the channel of Paging message needed cell after.
In addition, before step 102, can also comprise the step of obtaining terminal called priority, for example, the core net control appliance can obtain the priority of terminal according to the content of IMSI section, perhaps according to the subscription data of terminal, as terminal unit contractual Supplementary Service Code be exactly high-priority users etc., the embodiment of the invention does not limit the mode of obtaining terminal PRI.
Step 104: send the described message that disposes precedence information, described message is used for the access device of described terminal called ownership and seizes processing according to described precedence information.
The core net control appliance sends the described message that disposes precedence information and is specially, when disposing the precedence information of terminal called in the direct channel needed cell in Paging message, described core net control appliance sends described Paging message, and, the described message that disposes precedence information is passed through terminal called by the access device BSC that described terminal called belongs to; When in the emlpp of Paging message cell, disposing the precedence information of terminal called, described core net control appliance sends the access device BSC of described Paging message to described terminal called ownership, after described BSC receives described Paging message, be filled in the precedence information of described terminal called in the channel needed cell and send to terminal called.
Because described Paging message carries the precedence information of described terminal called, so, described terminal called sends channel request message to described BSC after receiving described Paging message, the coding that described BSC carries according to described channel request message is judged the precedence information of terminal called, and going forward side by side robs accounts for processing.
Because terminal called sends to the ability information that also can carry self in the channel request message of BSC, be meant that as " full rate only " terminal can only support full-rate codes, " dual rate " is meant that terminal can support full-rate codes and half rate encoded simultaneously, and " sdcch only " is meant that terminal can only processing signaling message etc.So when specific implementation, the coding of channel request message can be as shown in Table 1:
| MS Capability Paging Indication (NOTE 3) | Full rate only | Dual rate (NOTE 5) | SDCCH only |
| Any channel | 100xxxxx | 100xxxxx | 100xxxxx |
| SDCCH | 0001xxxx | 0001xxxx | 0001xxxx |
| TCH/F | 100xxxxx | 0010xxxx | 0001xxxx |
| TCH/H or TCH/F | 100xxxxx | 0011xxxx | 0001xxxx |
