Abstract
A method and network device for confirming ISR activation, optimize the way of activating ISR to solve the defects of prior art that the characteristics of the ISR can not be fully utilized, caused by activating ISR only depending on the EMM combined procedures capability reported by UE. The method comprises: serving general packet radio service (GPRS) support node (SGSN) obtains the subscription data of user equipment (UE); and SGSN activates ISR for the UE when SGSN confirms there is no circuit switch (CS) domain subscription data in the UE's subscription data. Meanwhile, in the present invention other two methods and network devices for confirming ISR activation are also disclosed.
