Embodiment
Below in conjunction with Figure of description the embodiment of the invention is elaborated.
In the embodiment of the invention, demand when operator from operation maintenance, need from the Serving GW of existing service, delete whole loads of a Serving GW, or the load on this Serving GW is need reduce the time, in order to guarantee the continuity of customer service, need all or part of carrying of this Serving GW is transferred among other Serving GW.
If this Serving GW that load is transferred is deployed in UTRAN and E-UTRAN boundary, then some UE among the UE that might be served is that ISR activates, for the UE that is in idle condition, the embodiment of the invention provides a kind of scheme of business continuance that as far as possible can guarantee simply, again to solve required Serving GW gravity treatment problem this moment.
As shown in Figure 2, among the embodiment, the handling process of the gateway of gravity treatment subscriber equipment is as follows:
In the enforcement, the load unloading command can be by O﹠amp; M (Operations﹠amp; Maintenance, operation and safeguard) system sends to gateway.
Behind the ISR of step 24, deexcitation UE, the described network equipment will be used to replace a Serving GW that the 2nd Serving GW of load service is provided the Serving GW as described UE.
In the flow process shown in Figure 2, step 21 is beginnings that Serving GW gravity treatment triggers, and works as O﹠amp; When the M system need change load between the service state of Serving GW or the different Serving GW of balance, O﹠amp; M is to Serving GW transmitting control commands, and the unloading command of promptly loading is in order to change loading condition.For ease of describing, the Serving GW of the load that title need change in the embodiment of the invention is a ServingGW, this moment, the one Serving GW needed to all MME and the indication of the reorientation in the SGSN forwarding step 22 that it connected, and requiring MME and SGSN is that the UE that is connected to this Serving GW reselects Serving GW.
An instantiation as shown in Figure 3, Serving GW gravity treatment triggers implementing procedure following (wherein, Old Serving GW is a Serving GW, and New Serving GW is the 2nd Serving GW):
It unloads load on it this command request, can specifically carry indication in the order and show that requirement unloads whole loads or fractional load.
Step 32, Old Serving GW send the reorientation indication to all MME and the SGSN of its connection.

When there is demand in operator, can pass through O﹠amp; M order as the load unloading command, sends to OldServing GW, requires it to unload load on it, can carry indication in the order, requires unloading all load or sub-load.
Step 42, Old Serving GW send the reorientation indication to all MME and the SGSN of its connection, and the load that requires MME and SGSN will be connected to Serving GW reduces.
Step 43, MME or SGSN send beep-page message to eNodeB or UTRAN.
MME or SGSN send beep-page message for being in idle condition and having activated the UE of ISR in eNodeB or UTRAN.
Step 44, eNodeB or UTRAN send beep-page message to UE.
Step 45, MME or SGSN receive the page response of UE.
Step 46, after MME or SGSN receive the page response of UE, at the ISR of this intranodal deexcitation UE.
Step 47-48, MME send deexcitation ISR indication to SGSN or SGSN to MME, return deexcitation ISR behind the deexcitation ISR and confirm.
In this process, MME or SGSN send deexcitation ISR indication to ISR associated the other side SGSN or MME, and this indication can also can be included in other S3 interface message separately as a message.
