Dynamic Group Policy Decision Entity for MBMS Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly those based on the 3GPP MBMS standard, lack the ability to dynamically manage MBMS bearers and process event notifications in real-time, limiting their functionality for applications like emergency response scenarios where dynamic group communications are essential.
Innovation Solution
A method and apparatus for handling group event notifications and provisioning policy rules in wireless communication systems, involving a group policy decision entity that receives and processes notifications to manage group transports, allowing for dynamic allocation of resources and switching between group and unicast transports based on policy rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MBMS-based systems use scheduled programming transmission, then system stability is maintained, but dynamic resource allocation capability is lost
Solution Approach 1:
The patent introduces dynamic policy rules that allow the system to adapt MBMS resource allocation in real-time based on current network conditions and service requirements. The policy decision entity dynamically adjusts bearer allocation, switching between scheduled programming mode and on-demand group communication mode, enabling the system to maintain stability while gaining adaptability.
2Productivity
If current policy rules are used for group sessions, then basic session management is achieved, but real-time dynamic management of group transports is impossible
Solution Approach 1:
The patent introduces a policy decision entity as an intermediary between the network infrastructure and group sessions. This entity receives group event notifications, evaluates them against stored policy rules, and makes real-time decisions about bearer allocation and resource management. This intermediary layer enables real-time dynamic management while abstracting the complexity from the underlying system.
Solution Approach 2:
The system implements a feedback mechanism where group event notifications are continuously monitored and fed back to the policy decision entity. This feedback loop enables real-time adjustments to group transport management based on actual network conditions and session requirements, improving productivity through responsive control.
3Adaptability or versatility
If scheduled programming transmission is used, then network resource efficiency is maintained, but emergency response and dynamic group communication capabilities are limited
Solution Approach 1:
The patent enables dynamic parameter changes in policy rules based on service type and network conditions. For emergency responses, the system can change parameters to prioritize group communication bearers, allocating resources dynamically. For normal scheduled programming, parameters are adjusted to optimize network resource efficiency. This parameter flexibility allows the system to adapt to different operational requirements.

AI summary
A group event processing entity receives and processes a group event notification wherein a set of policy rules is determined that controls the performance of an action as relates to at least one of a member user equipment of a group session or an access network resource for the group session. Additionally, a group policy decision entity receives a request to establish a group access network resource for a group of user equipment and determines a set of applicable policy rules for establishing the group access network resource, wherein the set includes a policy rule that controls performance of an action when a base station in a wireless access network is unable to provide resources to support the requested group access network resource. The group policy decision entity provides the set of applicable policy rules to a group policy enforcement entity.
