Network Identifier Maintenance for Wireless Resource Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in resource utilization, particularly when handling infrequent mobile terminated calls, as they maintain active connections and resources even when calls are not frequent, leading to wastage of network resources.
Innovation Solution
The method involves maintaining a network identifier for an access terminal while deleting AT-specific contexts and resources when not in use, allowing for the use of a common connection to initiate specific connections only when needed, thereby conserving resources and efficiently managing network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active connections and resources are maintained for access terminals with infrequent mobile terminated calls, then call service availability is ensured, but network resource utilization deteriorates due to wastage of allocated resources
Solution Approach 1:
The system dynamically adjusts the connection state of access terminals based on call activity patterns. Terminals transition between active connection state (when calls are frequent) and dormant state (when calls are infrequent), allowing the network to adapt resource allocation to actual usage needs rather than maintaining static resource reservations
Solution Approach 2:
The invention changes the operational parameters of access terminal connections by introducing a dormant state with modified resource allocation. In this state, essential parameters like network identifier and location information are maintained while non-essential parameters such as full context information and dedicated resources are released or shared, enabling efficient resource utilization while preserving service capability
2Reliability
If full context information is maintained for each access terminal, then service quality is improved, but device complexity and resource overhead increase
Solution Approach 1:
The system applies different quality levels of context information maintenance to different access terminals based on their specific needs and activity patterns. Frequently active terminals receive full context information treatment, while terminals with infrequent calls receive minimal context maintenance, optimizing the balance between service quality and system complexity
Solution Approach 2:
Context information is segmented into essential elements (network identifier, location) that are maintained in dormant state and non-essential elements (full service context, dedicated resources) that are released. This segmentation allows the system to maintain only the minimum necessary information while releasing excess complexity

AI summary
An apparatus and method for establishing a connection including reserving a common connection for use by more than one access terminal (AT); associating the common connection with a network identifier corresponding to the AT; deleting a network identifier-related context while maintaining the network identifier; and transmitting a message, based on a call to the AT, via the common connection and based on the network identifier, wherein a specific connection for carrying the call is based on a response to the message. In one example, the apparatus and method include conducting a registration session with a wireless communications network; obtaining a network identifier corresponding to the AT based on the registration session; deleting a network identifier-related context for the AT while maintaining the network identifier; receiving a message indicating a call destined for the AT; and establishing, based on the message, a specific connection for carrying the call.
