Abstract: Method, apparatus and communication system for resource release controlling are provided in the disclosure. When a user equipment (UE) with an idle mode signaling reduction (ISR) being activated moves from a first source network to a second target network, if a first SGSN in the first source network knows that a second SGSN in the second target network does not support interaction with a serving gateway (S-GW) and does not support ISR, the first SGSN controls the deletion of bearer resources on a MME in the first network by sending a resource deletion message.
Abstract translation: 本公开提供了用于资源释放控制的方法，装置和通信系统。 当激活空闲模式信令减少（ISR）的用户设备（UE）从第一源网络移动到第二目标网络时，如果第一源网络中的第一SGSN知道第二目标网络中的第二SGSN 不支持与服务网关（S-GW）的交互并且不支持ISR，所以第一SGSN通过发送资源删除消息来控制在第一网络中的MME上的承载资源的删除。
