Dynamic Multicast Broadcast Service Area Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multicast broadcast service areas are inflexible and cannot be adjusted in real-time, leading to wastage of radio spectrum resources as base stations broadcast irrelevant information to users outside the required area, due to pre-planned larger service areas that do not match actual application requirements.
Innovation Solution
A method and network apparatus that dynamically adjust the multicast broadcast service area by obtaining a cell list in a session update request message, allowing for real-time allocation or release of radio spectrum resources, enabling precise targeting of broadcast areas based on event-related information and geographic locations of base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If MBSFN areas are planned to have a larger area to satisfy various application service requirements, then the coverage area is improved, but radio spectrum resources are wasted as base stations broadcast irrelevant information to users outside the required area
Solution Approach 1:
The patent implements dynamic adjustment of MBSFN area boundaries through network apparatus that can modify the service area in real-time based on actual service requirements. The system transitions from static pre-planned areas to dynamic areas that adapt to service needs, allowing the broadcast coverage area to be optimized without wasting radio spectrum resources on irrelevant users.
Solution Approach 2:
The patent changes the parameter of MBSFN area boundaries from fixed pre-configured values to dynamically adjustable parameters. The network apparatus modifies area definition parameters based on service requirements, enabling the system to adjust coverage area and radio resource allocation together, thus avoiding resource waste while maintaining adequate coverage.
2Device complexity
If MBSFN areas are pre-planned with fixed boundaries, then the network configuration is simplified, but the broadcast area cannot be adjusted in real-time to match actual service requirements
Solution Approach 1:
The patent introduces dynamic adjustment capability to the MBSFN area configuration system. The network apparatus can modify area boundaries in real-time based on service requirements, transforming the system from static to dynamic without significantly increasing configuration complexity. This enables the broadcast area to adapt flexibly to different services and emergency situations.
Solution Approach 2:
The patent implements a feedback mechanism where the network apparatus monitors service requirements and automatically adjusts MBSFN area boundaries accordingly. The system receives feedback about actual service needs and modifies the broadcast area to match, enabling real-time adaptation while maintaining automated operation that does not substantially increase configuration complexity.
3Ease of operation
If telecom operator sends someone to perform relevant settings to change MBSFN area range, then the area can be adjusted, but it is impractical and cannot change the broadcast range in real-time or set different broadcast ranges for different application services
Solution Approach 1:
The patent implements self-service automation where the network apparatus automatically adjusts MBSFN area boundaries based on service requirements without manual intervention. The system independently determines the appropriate broadcast area and configures base stations accordingly, eliminating the need for manual settings while enabling real-time adjustments for different services and emergency situations.
Solution Approach 2:
The patent automates the parameter adjustment process for MBSFN area boundaries. Instead of manual configuration, the network apparatus dynamically changes area definition parameters based on service requirements, dramatically increasing the speed of area adjustment and enabling real-time reconfiguration for different application services without manual intervention.

AI summary
An aspect of the disclosure includes a method for adjusting a multicast broadcast service area. According to an exemplary embodiment, the method may include, but is not limited to, the following steps. A cell list in a session update request message is obtained. An old broadcast target area for a multicast broadcast service is adjusted to a new broadcast target area for the multicast broadcast service according to the cell list. At least one base station is controlled to allocate or release radio spectrum resources for the multicast broadcast service.
