Method, apparatus, and system for location update
First Claim
1. A location update method, comprising:
- when detecting that a location update needs to be performed in a first mobile communication network, sending a first request message comprising instruction information to a mobile management device in the first mobile communication network such that the mobile management device in the first mobile communication network sends a second request message to a mobile management device in a second mobile communication network when executing the location update according to the instruction information, wherein the second request message enables the mobile management device in the second mobile communication network to reset a periodic update timer and send a first accept message comprising a periodic update timer reset instruction of the second mobile communication network to the mobile management device in the first mobile communication network;
receiving a second accept message sent by the mobile management device in the first mobile communication network, wherein the second accept message comprises the periodic update timer reset instruction of the second mobile communication network; and
resetting the periodic update timer of the second mobile communication network according to the periodic update timer reset instruction of the second mobile communication network.

Abstract
A method, an apparatus, and a system for a location update are provided. When detecting that a location update needs to be performed in a first mobile communication network, a request message including instruction information is sent to a mobile management device in the first mobile communication network, so that the mobile management device in the first mobile communication network sends a request message to a mobile management device in a second mobile communication network when executing the location update, so as to trigger the mobile management device in the second mobile communication network to reset a periodic update timer, which implements that a location update of a single-card dual-standby user equipment is synchronously performed in the first mobile communication network and in the second mobile communication network.

10. A single-card dual-standby user equipment, comprising:
-
a radio frequency transceiver; and at least one processor coupled to the radio frequency transceiver, wherein the processor is configured to, when detecting that a location update needs to be performed in a first mobile communication network, trigger the radio frequency transceiver to send a first request message comprising instruction information to a mobile management device in the first mobile communication network such that the mobile management device in the first mobile communication network sends a second request message to a mobile management device in a second mobile communication network when executing the location update according to the instruction information, wherein the second request message enables the mobile management device in the second mobile communication network to reset a periodic update timer and send a first accept message comprising a periodic update timer reset instruction of the second mobile communication network to the mobile management device in the first mobile communication network; and when the radio frequency transceiver receives a second accept message comprising the periodic update timer reset instruction of the second mobile communication network and sent by the mobile management device in the first mobile communication network, reset the periodic update timer of the second mobile communication network according to the periodic update timer reset instruction of the second mobile communication network. - View Dependent Claims (11, 12)
