Abstract
The invention provides a method for keeping a user on line during a fault of an inverse multiplexing for an asynchronous transfer mode (IMA) group of radio network controller (RNC) equipment. In the method, when the IMA group on which the transfer carrier of the user is positioned has the fault, the RNC releases the radio link and the transfer carrier of the user on a backup IMA group; a resourceentity on a network side is released, so that the user is asynchronous with the network side quickly and initiates a new cell updating process; in the cell updating process, the RNC reallocates radiolink resources to the user, establishes a new transfer carrier on the backup IMA group and informs the user to use new null allocation information; and at the moment, a service is recovered to be normal, and the user is kept on line all the time. In the method, when a principal IMA group has the fault or a single plate on which the principal IMA group is positioned has the fault, the transfer carrier of the user is reallocated in the backup IMA group by triggering the user to initiate the cell updating process, so that the releasing of a signaling plane to an on-line user is avoided, the usercannot be disconnected in the fault recovering process, and the service recovering delay is short.
Description
[technical field]
The present invention relates to the wireless network communication technology, be particularly related to a kind of RNC (Radio Network Controller, keep the online method of user when radio network controller) equipment I MA (Inverse Multiplexing for ATM, inverse multiplexing for atm logical links) organizes fault.
[background technology]
See also shown in Figure 1ly, be the Iub interface protocol stack structure.Iub interface is the interface between RNC and the Node B (base station), is used for transmitting signaling between RNC and the Node B and the data of wave point.Iub interface can be divided into physical layer, transport layer and wireless network layer from level; Can be divided into wireless network control plane, transmission network control plane and user plane from function aspects.
See also shown in Figure 2, adopt two IMA assembly to put for RNC and Node B bottom, when the generation master uses ima group failure, RNC is to current on-line UE (User Equipment, mobile phone terminal) sends RRC and connect release (RRC CONNECTION RELEASE), UE returns RRC connection release and finishes (RRC CONNECTION RELEASE COMPLETE), RNC sends Radio Link removal request (RADIO LINK DELETE REQUEST) to Node B, Node B returns Radio Link deletion response (RADIO LINK DELETE RESPONSE), the transmission bearer that deletion UE exists in fault IMA group, so far the online user discharges fully.When inserting, new user sets up transmission bearer in standby IMA group.
Because RNC can initiate user's release flow process during the ima group failure of user's transmission bearer place, the call drop phenomenon will appear in the user, influence the performance of user's experience and system.
[summary of the invention]
Keep the online method of user when the purpose of this invention is to provide a kind of RNC equipment I MA group fault, can be main when switching to standby IMA group with ima group failure, the user is call drop not, and business can not interrupted.
To achieve these goals, the present invention adopts following technical scheme:
Keep the online method of user when a kind of RNC equipment I MA organizes fault, be used for comprising the communication system of RNC and Node B, described RNC comprises that the master organizes with IMA group and standby IMA, may further comprise the steps:
A) Radio Link main with behind the ima group failure, that RNC sets up for the online user by Radio Link removal request notice Node B deletion in standby IMA group, Node B return Radio Link deletion response indication Radio Link and delete successfully;
B) RNC notification transmission network layer discharges main with the transfer resource of setting up on the IMA group;
C) UE interrupts and can't initiate cell updating course under the recovery situation in business datum, and cell update message sends to Node B by the residential quarter Common transport channel, is transmitted to RNC by Node B by Iub interface;
D) the UE of RNC carries out cell update, sets up the Radio Link of asking newly-built this UE of notice NodeB by Radio Link, and Node B returns Radio Link foundation response indication Radio Link and sets up successfully;
E) RNC sets up new transmission bearer in standby IMA group for the exclusive Radio Link of UE;
F) RNC sends the cell update affirmation, and notice UE enables the new configuration of eating dishes without rice or wine;
G) UE receives and enables new configuration after cell update is confirmed, reshuffles by physical channel and finishes notice RNC configuration take-effective, and cell updating course finishes, and it is normal that the UE business function recovers.
Compared with prior art, the present invention has the following advantages: when the inventive method is organized place single board default with ima group failure or master with IMA the master, avoid discharging the online user at signaling plane, again put user's transmission bearer in standby IMA assembly but initiate cell updating course by the triggering user, the user can not go offline in this failover procedure, and recovery latency is short.

Fig. 1 is Iub interface protocol stack structure figure;
Fig. 2 is the ima group failure processing procedure figure in the existing system;
Fig. 3 is ima group failure processing procedure figure of the present invention.
[embodiment]
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail.
The present invention at standby IMA group release user's Radio Link, waits for that the user initiates cell updating course when the ima group failure at user's transmission bearer place, reconfigure user's air-link resources in cell updating course.
In order to realize this function, need RNC to discharge user radio link and the transmission bearer that fault IMA group is set up in standby IMA group, after user and the failure of base station uplink synchronous, the user initiates cell updating course, RNC reconfigures user's air-link resources by cell updating course, set up user's transmission bearer in standby IMA group, so that the user remains is online.
Concrete steps of the present invention are as follows:
A) main with behind the ima group failure, the Radio Link that RNC sets up for the online user by Radio Link removal request (RADIO LINK DELETE REQUEST) notice Node B deletion in standby IMA group, Node B returns Radio Link deletion response (RADIO LINK DELETE RESPONSE) indication Radio Link and deletes successfully;
B) RNC notification transmission network layer discharges main with the transfer resource of setting up on the IMA group;
C) because Radio Link is deleted, and UE interrupts and can't can initiate cell update (CELL UPDATE) process under the recovery situation in business datum, CELL UPDATE message sends to Node B by the residential quarter Common transport channel, is transmitted to RNC by Node B by Iub interface;
D) the UE of RNC carries out cell update, set up the Radio Link that newly-built this UE of Node B is notified in request (RADIO LINK SETUP REQUEST) by Radio Link, Node B returns Radio Link foundation response (RADIO LINK SETUP RESPONSE) indication Radio Link and sets up successfully;
E) RNC sets up new transmission bearer in standby IMA group for the exclusive Radio Link of UE;
F) RNC sends cell update affirmation (CELL UPDATE CONFIRM) notice UE and enables the new configuration of eating dishes without rice or wine;
G) UE enables new configuration after receiving cell update affirmation (CELL UPDATE CONFIRM), reshuffle by physical channel and to finish (PHYSICAL CHANNEL RECONFIGURATION COMPLETE) notice RNC configuration take-effective, cell updating course finishes, and it is normal that the UE business function recovers.
During the ima group failure at user's transmission bearer place, RNC discharges user's Radio Link and transmission bearer in standby IMA group, because the network side resource entity is released, the very fast step-out of user and network side, the user can initiate cell update (Cell Update) process, and RNC reconfigures user's air-link resources and sets up new transmission bearer in standby IMA group in cell updating course, notifies the user to adopt the new configuration information of eating dishes without rice or wine, this moment, business recovery was normal, and the user remains online.
