Mobile Station Network Access Identifier Syntax Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile stations face incompatibilities when attempting to form communication connections with UMA (Unlicensed Mobile Access) or GAN (Generic Access Network) networks due to differences in protocol versions, leading to failed access and communication disruptions.
Innovation Solution
A mobile station apparatus and method that generates signaling messages using alternative syntax formats for network access identifiers, maintaining a listing of successful syntaxes to facilitate communication connections with either UMA or GAN networks, allowing the station to adapt and retry with the correct syntax for successful connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile station uses a fixed protocol version (UMA or GAN) for communication, then the signaling messages are generated according to a specific syntax, but the mobile station cannot form a communication connection with networks operating on different protocol versions
Solution Approach 1:
The mobile station dynamically switches between UMA and GAN syntax based on network response. When a communication attempt fails with one syntax, the system automatically transitions to using the alternative syntax, enabling adaptation to different protocol versions without manual intervention
Solution Approach 2:
The system changes the syntax parameter of signaling messages based on connection success or failure. By modifying the message format (UMA syntax vs. GAN syntax) in response to network feedback, the mobile station can communicate with networks operating on either protocol version
2Productivity
If the mobile station attempts to connect using one syntax first, then connection may be established with compatible networks, but connection attempts fail with networks using different syntax requiring additional retry logic
Solution Approach 1:
The mobile station performs a preliminary connection attempt using a default syntax (e.g., UMA). Only when this initial attempt fails does the system switch to the alternative syntax (GAN), thereby minimizing the time lost to syntax switching while ensuring eventual connection success
Solution Approach 2:
The system uses feedback from the network's response (success or failure) to determine whether to switch syntax. This feedback-driven approach ensures that syntax switching occurs only when necessary, optimizing both connection speed and time efficiency

AI summary
Apparatus, and an associated method, for forming a communication connection between a mobile station and a communication network. The communication network is of either of two protocol versions, such as a UMA-compliant network and a GAN-compliant network. A network access identifier is formed at the mobile station of a format that permits its acceptance by the communication network. If a first network access identifier is formed of a format that is incompatible with the protocol version of the communication network, a subsequent network access identifier is formed of the format of the other of the protocol versions. A listing is maintained at the mobile station that identifies the determined protocol version of the communication network.
