Abstract
The invention discloses a reconstruction method for the direct signal connection, which is characterized in that a user equipment is used to send cell-update/URA-update massage to a drift radio network controller; after receiving the cell-update/URA-update massage, the drift radio network controller is used to send a radio resource connection release message and indicate the reason of radio resource connection release message to be the direct signal reconstruction; after the radio resource connection release message is received by the user equipment, a request of reconstructing the radio resource connection is made to the drifting radio network controller, which serves as a new service radio network controller. The invention has the advantages that the rapid and normal operation of the direct signal connection reconstruction procedure of the UE equipment is ensured; the normal operation of the various subsequent corresponding services of the UE equipment is guaranteed; the operation load of RNC equipment is lowered; the operation performance of the whole 3G system is improved.
Description
Technical field
The present invention relates to mobile communication technology, relate in particular to a kind of direct signaling connection reconstruction method.
Background technology
In the 3-G (Generation Three mobile communication system), comprise WCDMA (Wideband CodeDivision Multiple Access, Wideband Code Division Multiple Access (WCDMA)) system, and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, TD SDMA) system etc.With WCDMA system related protocol is example, carries out case study according to cell update flow process between UE (UserEquipment, subscriber equipment) equipment initiation RNC (Radio Network Controller, radio network controller).
In 3-G (Generation Three mobile communication system) WCDMA system, as shown in Figure 1, UE equipment is initiated RNC equipment room cell update flow process and is described below:
UE equipment resides among the service wireless network controller SRNC (Serving RadioNetwork Controller);
Along with moving of UE equipment, UE equipment sends cell update (Cell Update) message to floating radio network controller DRNC (Drift Radio Network Controller);
DRNC equipment sends up signaling transmission indication (UplinkSignalling Transfer Indication) message to SRNC equipment, and notice SRNC equipment UE equipment has been initiated the cell update request;
SRNC equipment is by sending downlink signaling transmission request (Downlink Signalling Transfer Request) message to DRNC equipment, notice DRNC equipment discharges the original Radio Resource of UE equipment and connects, and indicates that to discharge the reason that Radio Resource connects be the direct signaling connection reconstruction;
UE equipment rebulids Radio Resource to the DRNC device request and connects, and with this RNC equipment as new SRNC equipment;
After the Radio Resource connection was set up successfully, (triggering CN equipment discharged with the Iu of original SRNC equipment and is connected UE equipment for CN, CoreNetwork) equipment initiation Routing Area Update request flow process to core net;
Route district flow process is normally finished;
UE equipment and new SRNC equipment room are set up RAB, and UE equipment returns to original state, and business recovery is normal.So far direct signaling connection reconstruction flow process finishes.
Describe as can be seen from above-mentioned flow process, in direct signaling connection reconstruction flow process, after DRNC equipment is received the cell update message of UE equipment, must notify SRNC equipment, and by SRNC equipment structure Radio Resource connection release message, again by DRNC equipment notice UE equipment.Each equipment room interactive messages is a lot of in the whole flow process, can cause the failure of UE equipment direct signaling connection reconstruction flow process under certain condition:
If the signaling link transmission bearer of the DRNC equipment of triggering and SRNC equipment room breaks down, DRNC equipment can't send up signaling transmission indicating information to SRNC equipment, causes whole direct signaling connection reconstruction flow process failure;
Triggering two, DRNC and SRNC equipment are in whole direct signaling connection reconstruction flow process, and any one processing module occurs unusual, send failure such as message, apply for the failure of allocation process resource, all can cause whole direct signaling connection reconstruction flow process failure.
The result of above-mentioned two kinds of triggerings can make UE equipment direct signaling connection reconstruction flow process fail.UE equipment can't be learnt next step operation, causes the state of UE not confirmed, can't set up Radio Resource with RNC equipment for a long time and be connected, user's service disconnection.
Do not consider the problems referred to above in the 3G system related protocol at present, do not have effective clear and definite mechanism to avoid the generation of the problems referred to above.When above-mentioned situation took place, the failure of UE equipment direct signaling connection reconstruction directly caused UE equipment current business to be interrupted at once, and can't in time initiate various follow-up business, influences the network operation performance and the access performance of system greatly.Further, because the failure of UE equipment direct signaling connection reconstruction flow process may cause this UE equipment constantly to initiate the cell update flow process, influence the overall operation performance of system.
Therefore, need a kind of direct signaling connection reconstruction solution, can effectively reduce the probability of occurrence that causes the failure of UE equipment direct signaling connection reconstruction flow process.
