Mobile Station Network Access Identifier Syntax Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Incompatibilities between UMA and GAN protocols prevent mobile stations from forming communication connections with networks operating under different protocol versions, leading to access failures.
Innovation Solution
A method and apparatus that generate signaling messages with different syntaxes for network access identifiers, allowing a mobile station to attempt connections using both UMA and GAN formats, and maintain a listing to determine the correct syntax for subsequent sessions based on previous successes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile station uses a fixed protocol version (UMA or GAN) for network access, then it can maintain protocol consistency and simplify device design, but it cannot connect to networks operating under different protocol versions
Solution Approach 1:
The mobile station dynamically changes the syntax parameter of network access identifiers based on the detected network protocol version. When attempting to connect, the device first tries one syntax format, and upon failure, switches to an alternative syntax format corresponding to the other protocol version, enabling adaptation to different network types without requiring separate dedicated devices
Solution Approach 2:
The protocol version detection and syntax switching mechanism transforms the static protocol configuration into a dynamic adaptive system. The mobile station automatically detects whether the network operates under UMA or GAN protocols and adjusts its message syntax accordingly, allowing the same device to operate across multiple protocol versions through real-time parameter adjustment
2Reliability
If the mobile station attempts connection using the wrong syntax format, then it can identify incompatible networks, but it experiences connection delays and failed access attempts
Solution Approach 1:
The mobile station performs preliminary syntax validation by attempting connection with one syntax format before falling back to an alternative format. This preliminary attempt quickly identifies incompatible networks, and the pre-configured alternative syntax enables immediate retry without lengthy reconfiguration delays, reducing overall connection establishment time while maintaining high reliability
Solution Approach 2:
The connection attempt mechanism incorporates feedback from the network response (success or failure) to determine whether to retry with an alternative syntax format. When a connection attempt fails, the system receives feedback indicating protocol incompatibility and automatically adjusts its approach by switching syntax formats, creating a self-correcting connection process that improves success rate while minimizing delay

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.
