Description
Technical field
The present invention relates to the communications field, relate in particular to the changing method between a kind of wireless access system.
Background technology
In mobile communication system, the user is keeping professional situation upper/lower positions often to change, if Access Network wireless controller, as 3G (3rd Generation, 3G (Third Generation) Moblie) RNC (Radio Network Controller, radio network controller) or 2G (2nd Generation, second generation mobile communication) BSC (Base Station Controller, base station controller), judgement UE (User Equipment, subscriber equipment) signal of the cell-of-origin at place covers when dying down, and can select signal to cover better Target cell and switch.
Exist under the situation of Iur-g interface when between the BSC of the RNC of 3G and 2G, if RNC judgement UE need initiate to switch to 2G cell, it can select the Iur-g interface to switch fast so, and as shown in Figure 1, the detailed process of switching is as follows:
Step 101: the UE that is in talking state sends measurement report triggering RNC and carries out switch decision;
When step 102:RNC decision-making needs to initiate reorientation from the 3G sub-district to 2G cell, if have the Iur-g interface between the BSC at the Target cell place of this RNC and 2G (being target BS C), then send handoff request message by this Iur-g interface, for UE at Target cell application Radio Resource;
Step 103: after the target BS C distributing radio resource, respond the handoff request acknowledgement message to source RNC;
Step 104: after source RNC receives the handoff request acknowledgement message of target BS C, send switching command to UE, and in switching command, carry the wireless resource information that target BS C has been distributed for UE;
Step 105:UE inserts target BS C according to the information in the switching command, sends to switch to insert message;
Step 106: target BS C sends switching detection message by the Iur-g interface to source RNC after receiving that the switching of UE inserts, and informs that RNC this UE in source is attempting cutting to this target BS C;
Step 107:UE sends handoff completion message to target BS C after successfully inserting new channel;
Step 108: target BS C is when receiving the handoff completion message that UE sends, and also by Iur-g notification source RNC, UE successful switch arrives under this BSC;
Step 109: after source RNC receives the handoff completion message of target BS C transmission, think that UE switches success, discharges the resource of its cell-of-origin, and simultaneously this UE user side data is switched on the Iur-g interface.
UE is after switching to target BS C from source RNC, and the anchor point that arrives CN (Core Network, core net) still is retained in source RNC.
At this moment, for CN, the handoff procedure from RNC to BSC is invisible, just looks like to be the switching of RNC inside.UE need mail to CN again via source RNC after flowing to BSC for the upstream data of CN; It also all is to be dealt into source RNC that CN gives the downstream data flow of UE, and then is transmitted to target BS C.And for BSC, RNC just looks like to be a CN, and the message between RNC and the BSC is undertaken finishing the adaptation processing of A interface to the Iu interface by RNC alternately by A interface flow process.
Afterwards, user face data is also realized the exchange of 2G form to the 3G form by RNC, and the UE user side data is sent to RNC by the Iur-g interface from BSC, again by the RNC processing forward to CN, descending data also are to be sent to RNC from CN, arrive BSC through the RNC processing forward again.
This handover scheme that is undertaken by the Iur-g interface has been saved the time delay that RNC introduces in the resource set-up procedure of CN in whole handoff procedure, also reduced the probability that causes handoff failure because the CN resource is blocked simultaneously.
Because UE may be in mobile state always, it might move to the sub-district under another BSC from the sub-district under this BSC, when BSC initiates to switch between BSC according to the measurement report judgement needs of UE, need to initiate to switch requirement by the Iur-g interface.Because RNC is responsible for the adaptive of A/Iu mouth, thus RNC need imitate that the partial function of CN is finished and BSC between cut out flow process.
Also propose to solve in the prior art and UE has set up the situation of user plane bearer by the Iur-g interface under, carry out the method switched between BSC.

Step 212: after source BSC received mentioned order, the signaling that discharges a wireless mouthful of resource and an Iur-g interface was connected with user's face, and responded removing to RNC and finish message.
So far, whole handoff procedure is finished, and the UE user side data is sent to RNC by the 2nd Iur-g interface from target BS C, and arrives CN through the RNC processing forward.Descending data also are to arrive first RNC from CN, are sent to target BS C by the 2nd Iur-g interface then after RNC handles and arrive UE again.The variation of data flow trend as shown in Figure 5 before and after switching.
Two, handover scheme 2 between BSC
There is the 2nd Iur-g interface in this scheme proposals between RNC and target BS C, but this interface is not supported to use when user face data carries.As shown in Figure 6, its concrete switching flow comprises the steps:
Step 301:UE sends measurement report and triggers switching;
Step 302: source BSC sends to switch to RNC and requires message, carries Target cell CGI in the message, the channel type that current UE is used, Speech version information etc.;
Step 303:, just apply for Radio Resource to target BS C by the 2nd Iur-g interface if the RNC judgement can be used handover scheme 2;
Step 304: target BS C finishes allocation of radio resources after receiving resource request, send the Radio Resource response message to RNC, carry switching command and UE in the message in the DRNTI of this BSC (Drift Radio Network Temporary Identifier, the interim sequence number of drifting radio network) information;
After step 305:RNC receives the Radio Resource response message, the switching command that wherein comprises is sent to source BSC, sending reorientation to CN simultaneously requires message to set up the user face data carrying, in the Old of message BSS (Base Station System, base station system) to New BSS Information, add DRNTI information;
Step 306: source BSC issues switching command and gives UE;
After step 307:CN receives the reorientation requirement, send handoff request message to target BS C;
Step 308: target BS C finishes the foundation of A mouth resource, and with the DRNTI information among the Old BSS to New BSS Information with related in the idle wireless resource of step 304 li distribution, send the handoff request acknowledgement message to CN;
The handoff request that step 309:CN receives target BS C confirms, sends the reorientation order to RNC;
Step 310:UE inserts Target cell, sends to switch to target BS C and inserts message;
Step 311: target BS C sends switching detection message to CN after receiving the switching access of UE;
Step 312:UE sends handoff completion message to target BS C after successfully inserting new channel;
Step 313:BSC transmits handoff completion message and gives CN;
After step 314:CN receives message, send the Iu release command message, simultaneously user face data is switched to the A mouth from the Iu mouth to RNC;
After step 315:RNC receives message, send clear command to source BSC and come the resource of source of release BSC and an Iur-g signaling to be connected, respond the Iu Release complete to CN simultaneously with user's face;
Step 316: after source BSC receives clear command, discharge Radio Resource, and discharge an Iur-g signaling and is connected, and respond removing to RNC and finish message with user's face.
