Abstract
The invention relates to a method for realizing calling and called exchange assisted by a core network. After the core network receives a calling establishing request of a caller, the state and the positioning area of a called party are obtained under the assistance of a visitor location register (VLR) or a home location register (HLR) according to a called number; a radio network controller (RNC) number of the called party is obtained according to the position area to judge whether the caller and the called party belong to the same RNC, and carried calling user experience (UE) marks are increased when a paging is sent; the called party answers the calling for affirming; the core network sends radio access bearing (RAB) assign to the caller and the called party; the RNC searches and obtains IUUP entitative information through the UE marks and the relationships of the call to realize abutting joint through mutually communicating the connection relation; when the RAP assigns of the caller and the called party are finished and the called party answers the picking-up, a picking-up respond is sent out to switch in the calling. The invention utilizes local connection exchange of the IUUP to realize the local exchange of the caller and the called party in the same RNC, saves the sources of CN and RNC, and is helpful to improve the processing ability for the CN and the RNC, and meanwhile, the time delay of the call is shortened.
Description
Technical field
The present invention relates in the 3-G (Generation Three mobile communication system) by the auxiliary method that realizes exchange of CN (core net, Core Network).
Background technology
In 3-G (Generation Three mobile communication system), the integrated level of RNC (radio network controller, Radio Network Controller) equipment is very high, and the number of users of general RNC can reach hundreds of thousands even more.In this case, a large amount of callings occur in same RNC inside.But according to present agreement regulation, the exchange of calling is responsible for by CN, and RNC only is responsible for the access of calling.
Main in the prior art, the typical process of called connection is as follows: CN is after receiving the setup requests of caller, according to called number, in auxiliary called state and the position district thereof of obtaining down of VLR/HLR (VLR Visitor Location Register/attaching position register), if called do not have the active position district or shut down then return failure to caller, otherwise obtain called place RNC number according to the lane place, paging under this RNC, called callback is after confirming, CN sets up IUUP (RNC-CN interface user plane, Iu-User Plane) resource such as, initiate RAB (RAB to calling and called then, Radio Access Bearer) assigns, wait for that RNC initiates the IUUP initialization, realize IU mouth RFC (RAB combination indication, RAB sub-FlowCombination Indicator) alignment, at last after calling and called RAB appointment is finished, behind shake bell and off-hook, call through.
Another kind of typical flow is after obtaining called state, if called start is on the throne, initiates RAB to caller so earlier and assigns, and after waiting the RAB of caller to assign to finish, initiates called paging and RAB again and assigns.The call time of this flow process is generally than last a kind of long flow path.
Adopt the scheme of prior art, when although a large amount of callings occurs in same RNC inside, the exchange of calling out still needs to finish by CN, has increased Business Processing amount and the load of CN and RNC, has also reduced sense of experience of users degree of being subjected to because of having increased the time delay of calling out simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is two kinds of processing methods of proposition, realizes that the calling exchange of the inner calling and called that take place of same RNC is realized by RNC, with the business processing resources of saving CN and RNC, and shortens call delay.
The auxiliary first kind of scheme that realizes the method for calling and called exchange of core net of the present invention may further comprise the steps:
Steps A: after core net is received the setup requests of caller, according to called number, in auxiliary called state and the position district thereof of obtaining down of VLR/HLR;
Step B: core net obtains called place RNC number according to the lane place, and judges in view of the above when calling and called belong to same RNC, changes next step;
Step C: increase when core net is sent out paging and carry calling UE (user) sign; Called callback is confirming;
Step D: core net is initiated RAB to calling and called and is assigned;
Step F: RNC searches by the UE sign and obtains the IUUP entity information, and the intercommunication relation of continuing achieves a butt joint then;
Step G: after calling and called RAB appointment is finished, recalled off-hook, issue the off-hook response simultaneously, call through.
Calling subscriber identification among the described step C is meant IMSI (global mobile user identification) or TMSI (Temporary Mobile Subscriber Identity).
In such scheme, after the called callback in step C is confirmed, can also comprise need judging whether core net to issue ring-back tone, if not, then carry out step D to G; If, the step below then changeing:
Step D1: set up caller IUUP resource earlier and wait for that RNC initiates the IUUP initialization, initiate RAB to calling and called then and assign;
Step F 1:RNC searches by the incidence relation of UE sign and calling and obtains the IUUP entity information, and the intercommunication relation of continuing achieves a butt joint then; Set up the IU port transmission bearing, caller IUUP and core net IUUP butt joint;
Step G1: after calling and called RAB appointment was finished, recalled off-hook, core net discharged the IUUP resource, issued the off-hook response simultaneously, call through.
In such scheme, can according to whether the needs core net issue ring-back tone, the user's face extend information in RAB assigns is provided with different numerals.
In such scheme,
In the steps A,, then return failure to caller if called do not have active position or a shutdown.
Among the step B, if judge that calling and called belong to different RNC, then obtain called place RNC number according to the lane place, paging under this RNC, called callback is after confirming, CN sets up resources such as IUUP, initiate RAB (RAB to calling and called then, Radio Access Bearer) assigns, wait for that RNC initiates the IUUP initialization, realize IU mouth RFC (RAB combination indication, RAB sub-Flow Combination Indicator) alignment, at last calling and called RAB assign finish after, behind shake bell and off-hook, call through.
The auxiliary second kind of scheme that realizes the method for calling and called exchange of core net of the present invention may further comprise the steps:
After steps A 2:CN receives the setup requests of caller, set up the IU mouth resource that comprises IUUP of caller and wait for that RNC initiates the IUUP initialization, issue caller RAB and assign;
Step B2: after caller RAB assigned and finishes, CN was in auxiliary called state and the position district thereof of obtaining down of VLR/HLR;
Step C2:CN judges that according to called position district calling and called at same RNC, change next step;
Increase when step D2:CN sends out paging to RNC and carry the calling UE sign, as IMSI or TMSI.
Step e 2:CN receives called callback affirmation, assigns to the called RAB that issues;
Step F 2:RNC finds relevant caller IUUP entity according to the UE sign of carrying in the beep-page message after called IUUP foundation is finished, mutual with it, realizes that calling and called IUUP directly docks; The transfer resource of called IU mouth (as the AAL2 subchannel) need not to set up;
Step G2:RNC continues to finish RAB and assigns, and shakes bell and off-hook at last; CN discharges the IUUP and the transfer resource of the CN side of caller; Call through.
Calling subscriber identification among the described step D2 is meant IMSI or TMSI.
In step B2,, then return failure to caller if called do not have active position or be in off-mode.
In step C2, if judge main, calledly belong to different radio network controllers, then obtain called place radio network controller number according to the lane place, paging under this radio network controller, called callback is after confirming, core net is set up radio network controller-resources such as core network interface user face, assign to called initiation RAB then, wait for radio network controller initiation radio network controller-core network interface user face initialization, realize IU mouth RAB combination indication alignment, at last the calling and called RAB assign finish after, behind shake bell and off-hook, call through.
The present invention utilizes this locality butt joint exchange of IUUP, realizes this locality exchange of the calling and called in the same RNC, and the resource of having saved CN and RNC helps to improve the disposal ability of CN and RNC.Simultaneously because calledly do not need to carry out the defeated resource of IU oral instructions again and set up and the IUUP initialization, caller does not need to carry out the defeated resource of IU oral instructions yet and sets up and the IUUP initialization in some cases, and the time delay of calling has also shortened.
