MBMS Reception Status Feedback for User Counting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Multimedia Broadcast Multicast Service (MBMS) systems lack a sufficient technical solution for counting the number of broadcast or multicast users in operation, which is essential for resource management and service optimization.
Innovation Solution
A method and apparatus for transmitting a multimedia broadcast multicast service reception status message in a wireless communication network, where a terminal receives a radio resource control message from a base station and determines if it satisfies predetermined conditions to transmit the reception status message, allowing the base station and Multicell/Multicast Coordination Entity to count the number of receiving users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If MBMS transmits multimedia content to multiple users using point-to-multipoint mechanism, then resource consumption is reduced and network capacity is improved, but the system lacks ability to count receiving users for resource management
Solution Approach 1:
The patent implements a feedback mechanism where terminals report their MBMS reception status to the network side (eNodeB/MCE) by sending uplink messages containing their identities and service reception information. This feedback enables the network to count active receivers and make informed resource allocation decisions, resolving the information loss about user numbers while maintaining the efficient point-to-multipoint transmission model.
2Reliability
If dedicated channel is allocated to each user for MBMS reception, then user-specific service quality is ensured, but network resource consumption increases significantly
Solution Approach 1:
The patent employs dynamic channel allocation where the network flexibly assigns dedicated or shared uplink resources to terminals based on real-time reception status reports. When multiple terminals receive the same MBMS service, the network can dynamically share uplink resources for status reporting, reducing overall resource consumption while maintaining service quality through on-demand dedicated allocations when needed.
Solution Approach 2:
The patent creates a universal uplink message structure that serves multiple functions: terminal identification, service reception status reporting, and implicit user counting. This multi-functional message type enables the system to maintain service quality monitoring while efficiently counting receivers and allocating resources, reducing overall network resource consumption compared to separate dedicated channels for each function.
3Measurement precision
If MBMS system monitors reception status of all users continuously, then accurate user counting is achieved, but system complexity and signaling overhead increase
Solution Approach 1:
The patent implements preliminary action by having terminals proactively report their MBMS reception status to the network at designated times or when entering/leaving service areas. This advance reporting allows the network to maintain accurate user counts without continuous monitoring, reducing system complexity and signaling overhead while preserving measurement precision through periodic status updates.

AI summary
The invention proposes a method of transmitting a multimedia broadcast multicast service reception status message, wherein a terminal receives a radio resource control message from a base station; determines whether the radio resource control message satisfies a predetermined condition; and if the radio resource control message satisfies the predetermined condition, then the terminal transmits the multimedia broadcast multicast service reception status message to the base station, wherein the multimedia broadcast multicast service reception status message is used for identifying a multimedia broadcast multicast service being received by the terminal With the technical solution of the invention, the base station can obtain a reception status message, transmitted by the terminal, of at least one multimedia broadcast multicast service at the terminal side to thereby count the number of broadcast or multicast receiving users of the multimedia broadcast multicast service in operation and perform other relevant processes.
