Service Group Identifier for Mobile Control Channel Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication systems face inefficiencies in transmitting control information for multiple services, leading to wastage of radio resources due to the inclusion of extensive service identifiers and information in messages.
Innovation Solution
The proposed solution involves grouping services and transmitting control information using a service group identifier, allowing user equipment to process only relevant information, thereby reducing the message size and optimizing radio resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control information for multiple services is transmitted individually with full service identifiers, then each service can be accurately identified and controlled, but the volume of control information increases and radio resources are wasted
Solution Approach 1:
The patent merges multiple service identifiers into a single service group identifier. Instead of transmitting separate control information for each service, the system groups multiple services under a common identifier, allowing control information to be transmitted once for the entire group. This combining approach maintains service identification capability while significantly reducing the volume of control information on the air interface.
Solution Approach 2:
The service group identifier serves multiple functions simultaneously: it identifies a group of services, enables control information transmission for all services in the group, and allows user equipment to efficiently filter and process only relevant control information. This multi-functional approach eliminates the need for separate identifiers and control messages for each individual service.
2Loss of information
If all service identifiers are included in control messages, then complete service information is provided to user equipment, but the message size increases and processing complexity rises
Solution Approach 1:
The patent extracts only the essential identifying information (service group identifier) from the complete service information, separating it from detailed service parameters. User equipment can efficiently process the extracted group identifier to determine relevance, and only then retrieve or process detailed service information if needed. This extraction approach maintains information completeness while dramatically reducing message size and processing complexity.
3Reliability
If control information is transmitted for every service individually, then each service receives appropriate control attention, but radio resources are inefficiently utilized
Solution Approach 1:
The patent combines control information transmission for multiple services into a single unified message using service group identifiers. Instead of transmitting separate control messages for each service individually, the system transmits one control message that applies to all services within the group, thereby maintaining accurate service control while significantly improving radio resource efficiency and reducing energy consumption.

AI summary
A method of communicating a point-to-multipoint service in a wireless communication system comprises receiving through a control channel a first message comprising a first point-to-multipoint service group identifier associated with a first plurality of point-to-multipoint services for a predetermined area. The method also comprises receiving a second message through the control channel comprising a list of point-to-multipoint service identifiers associated with the first point-to-multipoint service group identifier. The method also comprises processing according to control information received through the control channel if the list of point-to-multipoint service identifiers comprises at least one service that a user equipment is subscribed to. The control channel may be a point-to-multipoint control channel. The first message may comprise a list of point-to-multipoint services associated with modified control information.
