Priority Control Channel for Wireless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication networks face challenges in providing reliable and efficient access to traffic channels for public safety agencies during network congestion, leading to potential communication failures in emergency situations due to high collision rates and dead spots.
Innovation Solution
Establishing a priority control channel within the wireless communication network for registered priority mobile stations, which can be activated when regular control channels are congested, ensuring less contention and increased likelihood of successful traffic channel allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If public safety agencies use private wireless networks with dedicated frequencies, then call reliability is improved, but network coverage and signal availability deteriorate
Solution Approach 1:
The patent combines public safety communications with commercial cellular networks, allowing public safety mobile stations to access both dedicated private network resources and commercial network infrastructure. This merging enables broader geographic coverage while maintaining reliable communication through coordinated access to multiple network types.
2Speed
If conventional cellular networks provide priority access to traffic channels, then access speed is improved, but communication reliability during congestion deteriorates
Solution Approach 1:
The patent segments the control channel access into priority and non-priority portions. Public safety mobile stations are granted dedicated priority control channels that are separated from commercial network traffic channels. This segmentation ensures that emergency communications can access the network rapidly without being blocked by congestion on shared traffic channels.
Solution Approach 2:
The system performs preliminary actions by pre-allocating priority control channels to public safety mobile stations before congestion occurs. These dedicated channels are reserved and prepared in advance, allowing immediate access during emergencies without waiting for available traffic channels, thus ensuring both speed and reliability.
3Reliability
If private wireless networks use specialized mobile stations, then communication reliability is improved, but device cost and complexity increase
Solution Approach 1:
The patent makes mobile stations universal by enabling them to operate on both private wireless networks and commercial cellular networks. Public safety mobile stations can function as specialized devices when accessing private networks for high-reliability communications, and as standard devices when utilizing commercial network infrastructure, reducing overall device complexity and cost.

AI summary
Systems and methods for priority wireless communications are provided. When a priority mobile station is registered with a wireless communication network, one or more base stations can establish a priority control channel for serving the priority mobile station. The priority control channel can be an uplink control channel for sending call setup requests, such as traffic channel allocations. The priority control channel can also be a downlink control channel for sending information to priority mobile stations.
