    • A resource release control method, a communication system, and a device are configured to delete a bearer context on an original-side heterogeneous-system management network element (NE) even if a target-side management NE does not support interaction with a serving gateway (S-GW) and does not support an idle mode signaling reduction (ISR) mechanism. The resource release control method includes: acquiring version information of a target-side management NE, when a user equipment (UE) activating an ISR mechanism is handed over from an original-side network to a target-side network; and deleting a bearer of an original-side heterogeneous-system management NE, if the version information indicates that the target-side management NE does not interact with an S-GW and does not support the ISR mechanism. Meanwhile, a communication system and a relevant device are also provided.
    • 资源释放控制方法,通信系统和设备被配置为即使目标侧管理网元不支持与服务网关的交互来删除原始侧异构系统管理网元(NE)上的承载上下文 (S-GW),不支持空闲模式信令减少(ISR)机制。 所述资源释放控制方法包括:当激活ISR机制的用户设备(UE)从原始侧网络切换到目标侧网络时,获取目标侧管理网元的版本信息; 如果版本信息表示目标侧管理网元不与S-GW交互,不支持ISR机制,则删除原边异构系统管理网元的承载。 同时,还提供通信系统和相关设备。
