Background technology
To the further exploration of 3G type of service, group service also becomes one of focus of discussion along with at present.The employing semiduplex mode of the basic service of group system, any member can become the speaker during the calling, but arbitrary moment only allow a speaker, other members are the hearer.Present existing group system does not also have ripe group system mainly based on GSM-R or CDMA technology in WCDMA/TD-SCDMA (wideband CDMA system/time-division synchronous CDMA system) system.
One of characteristics of group service are that " instant messaging " can be provided.Can not surpass 1 second service call settling time of especially professional cluster at most, and at present WCDMA system calling settling time basically all greater than 3 seconds.
The critical path of the calling procedure of existing WCDMA/TD-SCDMA is described below:
1, caller RRC (Radio Resource Control, Radio Resource control) connect foundation: calling UE (User Equipment, user terminal) sends RRC connection request (RRC CONNECTIONREQUEST) message, the RRC that request is set up between UE and the RNC (Radio Network Controller, radio network controller) connects.RNC receives behind the RRC connection request will be to connecting Resources allocation, and indication UE sets up RRC and connects.
2, the high-level signaling between UE and the CN (Core Network, circuit domain core net) connect to be set up: it is mutual to carry out high-level signaling between UE and the CN, mainly is that transmission is set up and called out required business request information, business and set up message etc.
3, after CN receives SETUP (foundation) message of UE, parse called number or group number, send beep-page message to the lane place at called place again.
4, after quilt is exhaled UE to receive the beep-page message of paging oneself or the own place of paging group, set up RRC with RNC and be connected, and send page-response message to CN.
5, CN and called UE connect, and set up to caller and called initiation service surface RAB/RB (RadioAccess Bearer/Radio Bearer, RAB/radio bearer).
6, called UE sends CONNECT (connection) message to calling UE, and calling/called connection is set up, and can begin conversation.
Its particular flow sheet as shown in Figure 1.Though the foundation that existing caller/called flow can be reliable is called out, call set-up time is longer, can't reach the primary demand of private network cluster.
At first, in existing flow process, caller and called air interface link setup are that serial is carried out: caller must be carried out the RRC link setup earlier, could send SETUP message (having carried called number or group number in this message); After CN parses called number, could send beep-page message to the lane place at called place; Calledly then also must carry out the RRC link setup earlier, could respond beep-page message, carry out the process that called Uu interface connects.
Secondly, set up between UE and the CN in the high-level signaling connection procedure, carried out repeatedly UE＜-direct transferring between CN, and these direct-sending messages all aloft interface send, speed is limited relatively owing to eat dishes without rice or wine, so the more time delay of calling out that also further prolonged of direct-sending message.
Therefore, the call setup flow process in the WCDMA system can not satisfy short calling and set up demand at present.Must the call flow of WCDMA/TD-SCDMA system be optimized, could satisfy the short calling of professional cluster service requirement and set up requirement.
Summary of the invention
The invention provides a kind of call connection establishing method, longer settling time in order to the call flow that solves WCDMA/TD-SCDMA system in the prior art, can not satisfy the problem that professional group service short calling is set up.
Call connection establishing method provided by the invention is applied to WCDMA or TD-SCDMA system, comprises caller link setup flow process and called link setup flow process, wherein:

Called receive beep-page message after, initiate to carry the RRC connection request message of page-response message to the radio network controller of callee side; And called and described callee side radio network controller finish RRC be connected set up before, described callee side radio network controller sends the information of page-response message to core net.
According to said method of the present invention, after described Calling Side radio network controller is received the RRC connection request message of caller transmission, send initial direct-sending message to core net, wherein comprise called number information.
Described called number information is carried by an immediate assignment message on the Iu interface, and described immediate assignment message comprises the connection management service request information and sets up the information of message.
The content of described immediate assignment message is included in the RRC connection request message that caller sends to described Calling Side radio network controller.
After described callee side radio network controller is received the RRC connection request message of called transmission, send initial direct-sending message to core net, comprising the information of page-response message.
The beneficial effect that the inventive method is brought is as follows:
1, because RNC has just sent to CN with called number information in the very first time, the RRC link setup that CN does not need to wait for calling UE just can begin called paging.Like this when Calling Side UE and RNC eat dishes without rice or wine the link setup flow process, callee side UE and the RNC link setup of also can eating dishes without rice or wine, the link setup of eating dishes without rice or wine that is calling subscriber and called subscriber can carry out simultaneously, thereby avoided the problem that caller and called link setup flow process serial are carried out in the prior art, reached the purpose that reduces call set-up time.
2, RRC connection request message (RRC CONNECTION REQUEST), connection management service request information (CM SERVICE REQUEST) and SETUP message are merged into an idle message after, reduce the space interface signaling message of UE and network side, reduced the signaling plane connection setup time between UE and the CN.
3, for called UE, after page-response message and RRC CONNECTION REQUEST merging transmission, RNC also just can not need to wait for that the just direct notice CN of RRC link setup has found called UE, and the paging that can reduce CN postpones to handle, and has reduced equally and has eated dishes without rice or wine to delay.
