Abstract
A method and device for a mobile terminal detaching are provided. The method comprises: upon deactivation, a mobile terminal starts a first timer, sends to a network apparatus deactivation indication information used to indicate that the mobile terminal is deactivated and keeps a registration state which is the same as the state that the mobile terminal was in before powering-off without performing a detach operation, such that the network apparatus starts a second timer to time synchronously with the first timer; and upon expiration of the first timer, the mobile terminal performs detachment operation if the mobile terminal is not reactivated.
Claims20
A method for a mobile terminal detaching, comprising:
- when the mobile terminal is powered off, starting a first timer, sending powering-off indication information to a network equipment, and keeping a registration state which is the same as the registration state that the mobile terminal was in before powering-off without performing a detach operation, wherein the powering-off indication information indicates that the mobile terminal has been powered off such that the network equipment starts a second timer which is aligned with the first timer;
- and
- when the mobile terminal has not been powered on till the first timer expires, performing, by the mobile terminal, the detach operation.
A method for a mobile terminal detaching, comprising:
- when a network equipment receives powering-off indication information sent by the mobile terminal, starting a second timer, and keeping a registration state which is the same as the registration state that the mobile terminal was in before powering-off without performing a detach operation, wherein the powering-off indication information indicates that the mobile terminal has been powered off, the second timer performs timing synchronously with timing of a first timer in the mobile terminal and the first timer is started upon the mobile terminal is powered off;
- and
- when the network equipment has not yet received powering-on indication information sent by the mobile terminal when the second timer expires, performing, by the network equipment, the detach operation, wherein the powering-on indication information indicates that the mobile terminal has been powered on.
A mobile terminal, comprising:
- a sending unit configured to, when the mobile terminal is powered off, start a first timer, send powering-off indication information to a network equipment, and keep a registration state which is the same as the registration state that the mobile terminal was in before powering-off without performing a detach operation, wherein the powering-off indication information indicates that the mobile terminal has been powered off such that the network equipment starts a second timer which is aligned with the first timer;
- and
- a processing unit configured to, when the mobile terminal has not been powered on till the first timer expires, perform the detach operation.
