Conversation Allocation Message Reduces Control Channel Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face inefficiencies in using radio communications bandwidth and core network resources, particularly for machine-type communications (MTC) due to the high overhead of allocation messages required for each signalling and data message, leading to congestion in control channels and inefficient data communication.
Innovation Solution
A communications system that employs a message processor and store to generate a conversation allocation message, which pre-allocates all necessary up-link and down-link resources for a predetermined set of message exchanges, reducing the need for individual allocation messages and improving resource allocation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual allocation messages are sent for each signalling and data message, then resource allocation can be performed, but communication overhead increases and control channels become congested
Solution Approach 1:
The patent combines multiple individual allocation messages into a single consolidated allocation message that allocates resources for multiple signalling and data messages simultaneously. This merging approach reduces the total number of messages transmitted over control channels, thereby reducing communication overhead and congestion while maintaining the ability to allocate resources for each message exchange.
Solution Approach 2:
The consolidated allocation message serves multiple functions by allocating resources for various types of messages (signalling messages, data messages, uplink, downlink) in a single transmission. This multi-functional approach eliminates the need for separate allocation messages for each message type, reducing overall communication overhead while preserving comprehensive resource allocation capabilities.
2Ease of operation
If individual allocation messages are used for each message exchange, then precise resource control is achieved, but control channel congestion increases
Solution Approach 1:
Multiple resource allocation operations are merged into a single consolidated allocation message that maintains precise control over resources for each individual message exchange. The message includes separate resource allocations for different message types (signalling, data) and directions (uplink, downlink), achieving both operational precision and channel efficiency.
3Adaptability or versatility
If traditional allocation messaging is used, then each message can be allocated independently, but resource allocation efficiency decreases
Solution Approach 1:
The patent merges multiple independent allocation operations into a single consolidated allocation message that maintains the ability to independently allocate resources for each message exchange. The consolidation improves efficiency by reducing messaging overhead while the structured format preserves adaptability for different message types and allocation scenarios.
Solution Approach 2:
The consolidated allocation message provides universal resource allocation for multiple message types (signalling, data), directions (uplink, downlink), and scenarios (predetermined message exchanges) within a single message structure. This multi-functionality maintains independent allocation capabilities while significantly improving overall resource allocation efficiency.

AI summary
A communications system, comprising a mobile radio network, the mobile radio network including a plurality of base stations arranged to communicate data to and from mobile communications devices via a wireless access interface. The mobile radio network is adapted to include a message processor and a message store, the message store being arranged to store an indication of each of one or more message exchanges in a set of predetermined message exchanges between the base stations and one or more of the communications devices, each message exchange comprising a predetermined set of predetermined messages and requiring predetermined up-link and/or down-link communications resource for communicating the message exchange on the up-link and/or down-link, between a base station and the communications device. The message processor is arranged in operation to generate, using the indication of the message exchanges stored in the message store, a conversation allocation message for communication to the mobile communications device, the conversation allocation message providing an indication to the mobile communications device of an allocation of communications resource on the down-link and/or the up-link for communicating the one or more messages of the message exchange, and to communicate the conversation allocation message to the mobile communications device, and in response to the conversation allocation message, the communications device and a base station to which the communications device is attached are arranged to communicate the messages of the message exchange using the resources allocated by the conversation allocation message. As a result, resources for a set of messages according to a predetermined message exchange can be allocated in a single conversation allocation message, rather than communicating an allocation message for each message of the message exchange, which is required for conventional mobile radio networks. Furthermore, there is a proportionate reduction in an amount of traffic communicated on a control channel such as the PDCCH for LTE.
