Abstract
The present invention discloses a method for deactivating ISR and a mobility management unit. Wherein the above method includes: when an ISR deactivation is needed to be performed, the mobility management unit judging whether to perform the following operation by the S-GW according to reasons of the ISR deactivation: the mobility management unit sends a request message of deleting bearer to the S-GW, and carries, in the request message, an identifier which is used to instruct the S-GW to initiate the bearer deletion to the other mobility management unit associated with the ISR function activation; or the mobility management unit notifies the other mobility management unit associated with the ISR function activation to perform the ISR deactivation. The synchronization between the bearer deletion and the network element state in the ISR function deactivation scenarios can be realized by the above technical scheme.

13. A method for deactivating ISR, which is applicable to a system comprising an S-GW and two mobility management units associated with ISR function activation, wherein the method comprises:
-
when an ISR deactivation is needed to be performed, the mobility management unit judging whether it is necessary to initiate a bearer deletion by the S-GW according to reasons of the ISR deactivation; in the situation that the judging result is necessary, the mobility management unit sending a request message of deleting bearer to the S-GW, and carrying, in the request message, an identifier which is used to instruct the S-GW to initiate the bearer deletion to the other mobility management unit associated with the ISR function activation; in the situation that the judging result is unnecessary, the mobility management unit notifying the other mobility management unit associated with the ISR function activation to perform the deactivation. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 24, 25, 26, 27, 28, 29, 30, 31, 32)

21. A mobility management unit, comprising:
-
judging means, when an ISR deactivation is needed, configured to judge whether it is necessary to initiate a bearer deletion by an S-GW according to reasons of the ISR deactivation; first processing means, configured to send a request message of deleting bearer to the S-GW, and to carry an identifier, in the request message, which is used to instruct the S-GW to initiate the bearer deletion to the other mobility management unit associated with an ISR function activation; second processing means, configured to notify the other mobility management unit associated with the ISR function activation to perform the ISR deactivation; wherein in the situation that the judging result of the judging means is necessary, the first processing means is performed;
otherwise, the second processing means is performed. - View Dependent Claims (22, 23)
