Data Over Signaling Optimization in Wireless Paging Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In CDMA-based wireless communication systems, the high latency and excessive call setup times in hand-offs and application signaling delivery hinder efficient transmission of delay-sensitive traffic, particularly in mobile networks, leading to increased air-link and network resource utilization and decreased throughput.
Innovation Solution
The method involves dynamically adjusting paging zones to minimize the transmission of application data over control channels by withholding application data until a page response is received, and configuring smaller paging zones for real-time applications, allowing for efficient delivery of application signaling while reducing call setup times and network resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If application data is transmitted over control channels in CDMA-based wireless communication systems, then call setup times are reduced, but air-link and network resource utilization increases
Solution Approach 1:
The patent applies preliminary action by transmitting application data over control channels before traffic channel establishment is complete. This allows the data to be pre-positioned in the network, enabling faster delivery once the traffic channel is ready, thereby reducing overall call setup time while managing resource utilization through controlled timing
2Area of stationary object
If paging zones are enlarged to improve mobile node connectivity, then coverage area increases, but transmission of application data over control channels increases
Solution Approach 1:
The patent applies local quality by dynamically adjusting paging zone sizes based on the specific needs of mobile nodes and the type of application data being transmitted. Instead of using uniform large paging zones for all scenarios, the system optimizes zone dimensions locally to match coverage requirements, thereby reducing unnecessary control channel transmissions while maintaining adequate coverage
3Adaptability or versatility
If data packets are transmitted across network boundaries using standard IP protocols, then communication between different networks is enabled, but latency increases for delay-sensitive traffic
Solution Approach 1:
The patent applies the intermediary principle by introducing optimized transmission mechanisms that act as mediators between standard IP protocol requirements and delay-sensitive application needs. The system uses control channels and optimized routing as intermediaries to bypass typical IP network latency, enabling fast delivery of delay-sensitive traffic while maintaining compatibility with standard network infrastructure

AI summary
The present invention supports a communication protocol on a wireless communication network to transmit application data on the control channel to an access terminal. Base transceiver stations are grouped and configured into paging zones. The radio network controller transmits a page message and application data to the base transceiver stations in the paging zone where the access terminal is located. Each of the base transceiver stations transmits a page and buffers the application data. The buffered application data is only transmitted by the base transceiver station receiving a response to the page.
