MBMS Paging for Dynamic Service Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing MBMS service transmission methods, users can only start receiving video data at the time of access, and the network cannot dynamically instruct users to receive temporarily initiated services, such as breaking news, in real-time.
Innovation Solution
A data transmission method where a base station receives an MBMS service transmission request and data from a core network, sends a paging message to user equipment (UE) to initiate service receipt, and configures transmission based on UE capabilities and thresholds, allowing dynamic notification and timely delivery of MBMS service data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unicast transmission manner is used to send user data independently to each user, then data delivery reliability is improved, but network resource consumption increases when multiple users need to receive the same data content
Solution Approach 1:
The patent combines unicast and multicast transmission modes into a unified MBMS framework. When multiple users need to receive the same data content, the system merges their reception into a single multicast transmission, thereby reducing network resource consumption while maintaining reliable delivery through the hybrid approach.
Solution Approach 2:
The patent implements dynamic transmission mode selection where the system can switch between unicast and multicast modes based on real-time conditions. The base station dynamically determines whether to use unicast for individual users or multicast for multiple users receiving the same content, optimizing network resource usage while ensuring reliable delivery.
2Loss of energy
If multicast transmission manner is used for real-time service, then network resource efficiency is improved, but the network cannot dynamically instruct users to receive temporarily initiated services
Solution Approach 1:
The patent implements preliminary action by having the base station send paging messages to user equipment before transmitting MBMS service data. This allows the network to dynamically notify users about temporarily initiated services (such as breaking news) and instruct them to receive the service, enabling flexible service initiation while maintaining efficient multicast transmission.
Solution Approach 2:
The patent incorporates feedback mechanisms where user equipment responds to paging messages by sending receiving acknowledgement messages. This feedback loop enables the network to dynamically adjust and confirm service reception status, enhancing the adaptability of multicast transmission for temporarily initiated services.
3Device complexity
If users can only receive video data from the time point of access, then system simplicity is maintained, but real-time reception of temporarily initiated services is not possible
Solution Approach 1:
The patent applies preliminary action by implementing a paging mechanism that notifies user equipment of upcoming MBMS service data transmission. Users can be dynamically instructed to receive temporarily initiated services through these advance notifications, enabling real-time service reception without significantly increasing system complexity.
Data Source
AI summary
The present invention relates to a data transmission method, apparatus, and system, where the method includes: receiving, by a base station, a Multimedia Broadcast Multicast Service MBMS service transmission request and MBMS service data that are sent by a core network device; after receiving the MBMS service transmission request or the MBMS service data, sending, by the base station, an MBMS service paging message in a cell served by the base station; and sending, by the base station, the MBMS service data to user equipment UE according to the MBMS service transmission request. According to the present invention, a dynamic notification message initiated by a network can be received, and when the network needs to send MBMS service data, a UE can receive the MBMS service data in time.
