Mobile Terminal Network Registration via Channel Resource Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals often fail to register with a network due to selecting cells with limited network resources even when better resources are available, leading to repeated registration failures.
Innovation Solution
The mobile terminal sorts available frequency channels based on pre-stored network resource status information, prioritizing channels with abundant resources and updating this information after registration attempts to optimize channel selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the mobile terminal preferentially scans frequency channels that are successfully decoded before and selects cells according to signal strength, then the network search speed is accelerated, but the mobile terminal may select cells with limited network resources leading to registration failure
Solution Approach 1:
The mobile terminal pre-stores network resource status information of frequency channels from previous registration attempts. Before re-registration, it retrieves this pre-stored information to identify frequency channels with abundant network resources, thereby avoiding cells that previously rejected registration requests. This preliminary action enables the terminal to prioritize frequency channels with better resource availability while maintaining accelerated network search through preferential scanning of previously decoded channels.
2Illumination intensity
If the mobile terminal selects cells with strong signals for registration, then the signal quality is improved, but the network resources may be insufficient leading to channel allocation rejection
Solution Approach 1:
The mobile terminal utilizes feedback from previous registration attempts in the form of pre-stored network resource status information. After a registration failure or successful registration, the terminal stores the network resource status of the corresponding frequency channel. During re-registration, it retrieves this feedback information to identify frequency channels with abundant resources, thereby selecting cells that both have strong signals and sufficient network resources, avoiding the channel allocation rejection problem.
3Loss of time
If the mobile terminal re-initiates network registration by scanning previously decoded frequency channels, then the registration process is accelerated, but it may repeatedly fail to register due to selecting the same limited-resource cells
Solution Approach 1:
The mobile terminal dynamically adjusts its frequency channel selection strategy based on pre-stored network resource status information. Instead of statically selecting frequency channels only by signal strength, the terminal dynamically incorporates resource availability data from previous registration attempts. This dynamic adjustment allows the terminal to accelerate registration by preferentially scanning previously decoded channels while simultaneously improving success rate by avoiding frequency channels with limited resources identified through stored feedback.

AI summary
A network registration method and apparatus, and a mobile terminal are presented. During re-registration with a network, after receiving a channel allocation rejection message sent by the network, a mobile terminal sorts all available frequency channels according to network resource statuses of frequency channels with which network registration failed before and that are in a low priority list. And then the mobile terminal tries to camp on all the available frequency channels according to an order of the sorting to determine a frequency channel to be camped on. The mobile terminal sends a network registration message to register with the frequency channel to be camped on.
