Media Service Parameter Indication for RAN Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies cannot effectively estimate terminal status in a radio access network (RAN) to optimize media service scheduling, leading to poor user experience due to network jitter and inadequate service selection.
Innovation Solution
A method and system that acquire and send media service flow configuration parameters, including data packet sequence number, current connection status, media information, and media play time, from a gateway GPRS support node (GGSN) or packet data network gateway (PGW) to the RAN, enabling the RAN to estimate terminal status and perform wireless scheduling for better service selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless scheduling is performed without terminal status estimation, then device complexity is reduced, but user experience quality deteriorates due to network jitter and inadequate service selection
Solution Approach 1:
The patent introduces an intermediary mechanism where the GGSN/PGW extracts media service flow configuration parameters and transmits them to the RAN. This intermediary approach allows the RAN to obtain terminal status information without the RAN itself performing complex packet inspection, thus improving user experience while distributing system complexity appropriately across network elements
Solution Approach 2:
The GGSN/PGW performs self-service by automatically extracting media service flow configuration parameters from passing data packets and making this information available to the RAN. This eliminates the need for manual configuration or complex coordination, enabling the system to improve scheduling quality through automated parameter acquisition
2Measurement precision
If media service flow configuration parameters are transmitted from GGSN/PGW to RAN, then scheduling precision is improved, but information transmission complexity increases
Solution Approach 1:
The patent applies extraction by having the GGSN/PGW extract only the necessary media service flow configuration parameters (such as media type, bandwidth, packet interval) from the complex stream of data packet information. By taking out only the essential parameters needed for scheduling decisions, the system achieves precise terminal status estimation while minimizing the complexity of information transmission to the RAN

AI summary
A method, an apparatus and a system for acquiring media service parameter indication are disclosed. In an embodiment the method includes acquiring, by a gateway GPRS support node (GGSN) or a packet data network gateway (PGW), a media service flow configuration parameter indication, wherein the media service flow configuration parameter indication comprises at least one of the following: a data packet sequence number, a current connection status, media information, or media play time and sending, by the GGSN or the PGW, the media service flow configuration parameter indication to a serving GPRS support node (SGSN) or a serving gateway (SGW). The method further includes sending, by the SGSN or the SGW, the media service flow configuration parameter indication to a radio access network (RAN) and acquiring, by the RAN, the media service flow configuration parameter indication.
