User Equipment Service Priority Determination for Group Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack the ability to prioritize group communication services over general MBMS or unicast services, which hinders resource efficiency and user experience.
Innovation Solution
A method and wireless equipment that enable user equipment (UE) to determine and prioritize group communication services over non-group communication services by transmitting an uplink message with indicators, specifying the priority of MBMS bearers over unicast bearers, allowing the network to manage resource allocation effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If group communication service is transmitted through MBMS or unicast bearer without priority differentiation, then system complexity is reduced, but service quality and resource allocation efficiency deteriorate
Solution Approach 1:
The patent applies local quality by introducing priority differentiation specifically for group communication services while maintaining the existing MBMS framework. The network device determines priority based on service type (group communication vs. general MBMS) and transmission mode (MBMS bearer vs. unicast bearer), allowing differentiated resource allocation without redesigning the entire system. This resolves the contradiction by adding complexity only where needed (priority determination for GC services) while preserving overall system simplicity.
2Productivity
If priority differentiation is implemented for group communication services, then resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by having the network device determine service priorities before resource allocation occurs. The priority determination is performed in advance based on service type and transmission mode, allowing the scheduler to efficiently allocate resources without complex real-time calculations. This resolves the contradiction by performing the complex priority determination work beforehand, simplifying the actual resource allocation process.
Solution Approach 2:
The patent applies parameter changes by introducing priority parameters (first priority for GC over non-GC, second priority for MBMS over unicast) that modify the resource allocation behavior. These parameters are determined based on service characteristics and are used by the scheduler to make allocation decisions. This resolves the contradiction by using simple parameter-based differentiation rather than complex algorithms, improving resource allocation efficiency while minimizing device complexity.
3Loss of energy
If MBMS bearer is used for group communication service, then resource efficiency is improved, but service priority over unicast service cannot be guaranteed
Solution Approach 1:
The patent applies segmentation by dividing MBMS services into two categories: group communication services and general MBMS services. This segmentation allows the network device to apply different priority rules to different service types. GC services received via MBMS bearer are assigned first priority over non-GC services, while maintaining the resource efficiency benefits of MBMS transmission. This resolves the contradiction by segmenting the service types to enable priority differentiation without sacrificing resource efficiency.

AI summary
There is provided a method for determining priorities of services. The method may be performed by a user equipment (UE) and comprise: determining, by the UE, whether to prioritize a group communication (GC) service over a non-GC service, wherein the GC service is received through a multimedia broadcast multicast service (MBMS) bearer or through a unicast bearer; and transmitting, from the UE and to a network, an uplink message including an indicator for indicating that the GC service is prioritized over the non-GS service.
