Abstract: Bearer context maintained by an access terminal is synchronized with a network so that a change in the status of the bearer context may be reflected at the network. For example, if an access terminal determines that a resource previously requested by the access terminal is no longer needed, the access terminal may deactivate the bearer context locally in a case where the access terminal is unable to communicate with the network. In such a case, the access terminal may synchronize its bearer context with the network once the access terminal reestablishes communication with the network. For example, the access terminal may send a message to the network indicating that the access terminal has deactivated the bearer context.

Abstract: A method for user detachment when a handover or change occurs in a heterogeneous network is provided. The method includes: a user equipment (UE) is handed over or switched from a source network to a target network; a network element on a network side determines whether to detach the UE from the source network, and if yes, the network element on the network side detaches the UE from the source network. A system and a device for user detachment when a handover or change occurs in a heterogeneous network, and another method for user detachment when a handover or change occurs in a heterogeneous network are also provided.

Abstract: 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.

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.
