Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing multicast context activation process in wireless communication systems is complex, leading to increased complexity in network deployment and inefficient data transmission due to the need for multiple APNs and IGMP Join data packet interception, which affects multicast service efficiency and resource utilization.
Innovation Solution
A new multicast communication method that simplifies the multicast context activation process by integrating multicast IP descriptors into the URSP rules, allowing for efficient multicast service activation through enhanced UE policy management and reduced network complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing multicast context activation process is used with multiple APNs and IGMP Join data packet interception, then multicast service can be provided, but network deployment complexity increases
Solution Approach 1:
The patent extracts the IGMP Join data packet interception function from the complex multi-APN architecture and consolidates it into a single APN configuration. The network side device directly intercepts and processes IGMP Join packets without requiring multiple APNs, thereby reducing network deployment complexity while maintaining multicast service reliability
Solution Approach 2:
The patent makes a single APN serve multiple functions: it handles both unicast and multicast traffic, and the network side device performs multiple operations (packet interception, context activation, service provision) through this unified APN configuration, eliminating the need for separate APNs for different functions
2Reliability
If the existing multicast context activation process is used with multiple APNs and IGMP Join data packet interception, then multicast service can be provided, but data transmission efficiency decreases
Solution Approach 1:
The patent implements preliminary action by having the network side device pre-establish the multicast context and prepare for IGMP Join packet interception before actual data transmission begins. This allows the system to respond more efficiently when multicast data needs to be transmitted, avoiding delays associated with complex multi-APN setup
Solution Approach 2:
The patent merges the multicast context activation process with the single APN configuration, combining what were previously separate processes (multiple APN setups, multiple interception points) into a unified flow that reduces processing steps and improves data transmission efficiency

AI summary
Provided are a multicast communication method and a related apparatus. The multicast communication method comprises: receiving URSP information sent by a policy control function entity, wherein the URSP information includes a URSP rule that supports a multicast service; according to a multicast network address corresponding to multicast service context needing to be activated, querying the URSP rule that supports a multicast service, so as to obtain network slice information and data network name information; and on the basis of the network slice information and the data network name information, activating MBS context information of a user equipment so as to join a multicast group corresponding to the multicast network address to perform multicast communication. By means of the technical solution in the embodiments of the present application, the number of activation processes of multicast service context can be reduced, thereby facilitating a reduction in the complexity of network deployment.
