Synchronous Location Update for Dual-Standby User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the coexistence of high-speed and low-speed mobile communication networks, single-card dual-standby user equipment frequently performs location updates in both networks, leading to unnecessary electric energy loss due to continuous activation.
Innovation Solution
Implementing a method for synchronous location updates in both mobile communication networks, where a request message is sent to reset the periodic update timer in the second network, allowing simultaneous updates and reducing unnecessary activations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the single-card dual-standby user equipment executes location update in both mobile communication networks independently, then the location update is completed in each network, but the user equipment is continually activated causing unnecessary electric energy loss
Solution Approach 1:
The patent merges the location update operations of two independent networks into a single synchronized operation. When a location update is triggered in the first network, the system automatically coordinates with the second network to perform the update simultaneously, combining what were previously two separate activations into one unified operation, thereby reducing energy consumption while ensuring both networks receive updated location information
Solution Approach 2:
The system implements a feedback mechanism where the completion of a location update in one network triggers a coordination signal to the other network. The mobile management device monitors the periodic update timer and, upon expiration, initiates a synchronized update across both networks by sending appropriate signaling messages, ensuring that location information is updated in both networks without requiring two independent activations
2Reliability
If the periodic update timer expires in one network, then the location update is triggered, but the user equipment must also activate for location update in the other network
Solution Approach 1:
The system performs preliminary coordination between networks before the second activation would occur. When the periodic update timer expires in the first network, the mobile management device proactively initiates a synchronized location update in the second network through signaling messages, ensuring both networks are updated in advance of what would otherwise be a separate activation event, thereby reducing the frequency of user equipment activations

AI summary
Embodiments of the present invention relate to a method, an apparatus, and a system for a location update. 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, and can avoid a problem in the prior art that the single-card dual-standby user equipment is continually activated to execute the location update, thereby effectively reducing unnecessary electric energy loss of the single-card dual-standby user equipment.
