Immediate Assignment Message for M2M Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications technologies, especially for 'machine-to-machine' (M2M) communication, a large number of terminals randomly initiating access requests overwhelm the network, leading to insufficient resource immediate assignment on the downlink Access Granted Channel (AGCH), as existing methods are inefficient in handling multiple channel requests simultaneously.
Innovation Solution
Constructing an immediate assignment message that combines channel request information from multiple terminals, using offset values to reduce the number of bits required for frame number parameters, and including only necessary packet resource parameters, allowing one message to allocate resources for multiple terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single immediate assignment message is used to assign resources to one terminal, then the message structure is simple and easy to decode, but the resource allocation efficiency is low when handling multiple terminals
Solution Approach 1:
The patent combines channel request information from multiple terminals into a single immediate assignment message. The message includes a frame number field that can indicate multiple frame numbers, allowing one message to allocate resources for multiple terminals simultaneously, thereby improving resource allocation efficiency while managing message complexity through structured design
Solution Approach 2:
The immediate assignment message is designed to serve multiple functions: it can assign resources to multiple terminals, indicate multiple frame numbers, and provide packet resource parameters. This multi-functionality allows a single message structure to handle complex resource allocation scenarios without requiring separate messages for each terminal
2Reliability
If the immediate assignment message includes complete frame number information for multiple terminals, then all terminals can be uniquely identified, but the message length exceeds the 176-bit limit
Solution Approach 1:
The patent changes the parameter representation by using a frame number field that can indicate multiple frame numbers in a compressed format. Instead of using separate 16-bit frame number fields for each terminal, the message uses a unified frame number indication mechanism that reduces overall message length while maintaining the ability to uniquely identify multiple terminals
3Reliability
If the network sends individual immediate assignment messages to each terminal, then each terminal receives dedicated resource allocation, but the downlink AGCH channel becomes overwhelmed with large numbers of MTC terminals
Solution Approach 1:
The patent merges multiple individual resource allocation operations into a single immediate assignment message. By combining channel request information from multiple terminals and allocating resources through one message, the system reduces the total number of messages on the downlink AGCH channel, preventing channel overload while maintaining accurate resource allocation for each terminal

AI summary
Embodiments of the present invention disclose a method, an apparatus, and a system for resource immediate assignment, which includes: constructing an immediate assignment message according to channel request messages of at least two terminals, where the immediate assignment message assigns a channel resource for the at least two terminals according to the channel request messages of the at least two terminals; and sending the immediate assignment message out. By implementing the embodiments of the present invention, in a case that a valid byte of an immediate assignment message is unchanged, one immediate assignment message can assign a packet resource for at least two terminals, thereby satisfying an access requirement of more terminals.
