Mobile Terminal Network Registration via Time Array Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network registration methods for mobile terminals have a low success rate when Tracking Area Update (TAU) is rejected, as they do not effectively switch to alternative networks or re-register with different Tracking Area Identities (TAIs), leading to connectionless network service states.
Innovation Solution
A method and apparatus for a mobile terminal that reads a time array to determine when to switch from a failed network registration attempt to an alternative network and re-register using the TAI of an adjacent cell, enhancing the registration success rate by alternating between different networks and timers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal stops registering the 4G network when TAU is rejected, then the device avoids repeated failed registration attempts, but the network registration success rate decreases
Solution Approach 1:
The patent implements dynamic network registration strategy where the mobile terminal adapts its registration behavior based on the TAU rejection state. When TAU rejection is detected, the system dynamically switches from active registration to a timed waiting state, then dynamically re-attempts registration with modified parameters (different TAI) after the timeout period, creating a flexible adaptive registration mechanism that resolves the contradiction between avoiding repeated failures and maintaining registration success rate
Solution Approach 2:
The patent changes the TAI parameter when re-registering the 4G network after TAU rejection. By modifying this identification parameter and using a different tracking area identity, the mobile terminal can successfully register with the network even after initial rejection, thereby improving the network registration success rate without continuously attempting failed registrations
2Reliability
If the mobile terminal continuously attempts to register the 4G network after TAU rejection, then the network registration success rate improves, but the device consumes excessive time and resources
Solution Approach 1:
The patent implements periodic registration attempts with a specific timeout interval between attempts. Instead of continuous registration attempts, the system waits for a predetermined timeout period after TAU rejection before re-attempting registration with modified parameters. This periodic approach balances the need for successful registration with the need to conserve time and resources, preventing infinite loops of failed attempts
Solution Approach 2:
The patent performs preliminary detection of TAU rejection state before initiating repeated registration attempts. By detecting the rejection state in advance and setting a timeout period, the system prepares for potential re-attempts without immediately consuming resources. This preliminary action allows the system to make informed decisions about when to re-attempt registration, reducing unnecessary time consumption

AI summary
Provided are a network registration method for a mobile terminal, a mobile terminal and a storage medium. The network registration method for a mobile terminal is implemented as follows. An element Ti in a time array is read in response of determining that a predetermined abnormal event occurs when a mobile terminal registers a first network. i is a positive integer between 1 and N, and N is a positive integer. The mobile terminal is prohibited from registering the first network. The mobile terminal is controlled to register a second network. A timer is started for timing to obtain a first counted time. It is determined whether the first counted time reaches Ti. A first identity is acquired if the first counted time reaches Ti. The first identifier is a tracking area identity of an adjacent cell of a registered cell when the first network is registered. The mobile terminal is controlled to re-register the first network again according to the first identity.
