Bundled Message Access Channel for PTT Call Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Push-To-Talk (PTT) wireless communication systems face delays in call setup due to slow cellular network infrastructure, leading to potential resource unavailability and false floor grants, especially when target mobile devices lack resources.
Innovation Solution
A system and method that allow wireless communication devices to bundle messages and send them in access channel communication packets, enabling the base station to quickly determine resource availability without examining all messages, thus expediting PTT communication setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple messages are sent individually through existing cellular network infrastructure, then each message can be processed sequentially, but the call setup time increases and latency increases
Solution Approach 1:
The patent combines multiple resource request messages into a single bundled message transmitted over the access channel. Instead of sending separate messages for each resource request, the system merges them into one packet that can be quickly transmitted and processed, thereby reducing call setup latency and improving speed.
Solution Approach 2:
The patent enables preliminary bundling of multiple messages before transmission. By preparing and combining messages in advance into a bundled format, the system reduces the time required during actual call setup, as the messages are already organized and ready for rapid transmission without requiring sequential processing.
2Reliability
If the base station reviews all messages in an access channel packet, then resource availability can be checked, but device complexity and processing overhead increase
Solution Approach 1:
The patent extracts and processes only the essential bundled message information needed for resource availability determination. Instead of reviewing every single message individually, the base station extracts key resource request indicators from the bundled packet, reducing processing complexity while maintaining reliable resource availability checks.
Solution Approach 2:
The patent implements partial message review by examining only the necessary portions of bundled messages required for resource allocation decisions. The base station performs sufficient review to determine resource availability without processing every detail of each bundled message, thereby reducing complexity while ensuring reliable resource management.
3Productivity
If messages are bundled and sent quickly over the access channel, then call setup time is reduced, but the risk of resource unavailability and false floor grants increases
Solution Approach 1:
The patent incorporates feedback mechanisms where the base station quickly determines resource availability based on bundled messages and provides appropriate responses. The system uses feedback loops to verify resource status and confirm floor grants, ensuring reliability even though messages are transmitted and processed rapidly through the access channel.
Data Source
AI summary
A system, method, and computer device that allow a wireless communication device to selectively bundle messages in an access channel communication packet being sent to another computer device on the wireless communication network, such as a base station are disclosed. The bundled messages are typically sent in response to a request sent to the wireless communication device for response to a specific event, such as the setup of a group communication call. The receiving computer device determines if the access channel communication packet contains data indicating one or more bundled messages are therewithin such that resources only then will expended to review the bundled messages to check for the availability of the requested resources.
