GCS AS Node State Query for MBMS Congestion Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MBMS bearer-based group communication systems lack a method for the Group Communication Service Application Server (GCS AS) to query and respond to network node states, leading to inefficiencies in resource management and user experience due to congestion or overload.
Innovation Solution
A method and system where the GCS AS requests and receives network node state information, including congestion/overload identifiers, to select optimal communication modes, such as switching to unicast or queuing messages, to mitigate network congestion or overload, using established MBMS bearers and network nodes like eNodeB, MCE, MME, MBMS GW, and BM-SC.

1Productivity
If GCS is sent through MBMS bearer, then resource utilization is improved, but network congestion or overload occurs
Solution Approach 1:
The patent implements a feedback mechanism where the network node reports its state (congestion/overload status) to the GCS AS. The GCS AS queries the network node state by sending a request message, and the network node responds with state information including congestion identifiers and overload identifiers. Based on this feedback, the GCS AS dynamically selects the appropriate communication mode (MBMS or unicast) to balance resource utilization and network reliability.
Solution Approach 2:
The patent enables dynamic mode selection between MBMS and unicast communication based on real-time network conditions. The GCS AS transitions from a static deployment approach to a dynamic one where the communication mode adapts to changing network states. When the network is congested or overloaded, the system dynamically switches to unicast mode for affected UEs, while maintaining MBMS mode for others, thus optimizing both resource utilization and service reliability.
2Device complexity
If GCS AS deploys GCS without querying node state, then system complexity is reduced, but service quality deteriorates due to congestion impact
Solution Approach 1:
The patent introduces a state query feedback mechanism where the GCS AS actively queries the network node state before deploying GCS. The system sends request messages to network nodes and receives state information including congestion identifiers and overload identifiers. This feedback enables the GCS AS to make informed deployment decisions, improving service quality while adding manageable complexity through standardized message exchanges.
3Ease of operation
If network node state is not monitored, then operational simplicity is maintained, but congestion impact on GCS reception increases
Solution Approach 1:
The patent implements automated state monitoring through feedback mechanisms where network nodes proactively report their state to the GCS AS. The GCS AS sends query requests and receives responses containing congestion and overload status. This automated feedback system reduces operational complexity by eliminating manual monitoring while effectively mitigating congestion impact through dynamic mode selection.
