Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the control plane and media plane are integrated in PoC service, then the system structure is simple, but technology evolution and service flexibility are hindered
Solution Approach 1:
The patent applies segmentation by dividing the integrated PoC service into separate control plane and media plane components. The control plane handles signaling and control messages (floor requests, grants, releases), while the media plane handles actual voice data transmission. This separation allows independent evolution and optimization of each plane, resolving the contradiction between simple structure and service flexibility.
2Adaptability or versatility
If the control plane and media plane are separated, then service flexibility and technology evolution are improved, but system complexity increases
Solution Approach 1:
The patent introduces a floor control function as an intermediary component that mediates between the control plane and media plane. This mediator manages floor requests, grants, and releases, coordinating control signals with media transmission. By introducing this intermediary layer, the system achieves plane separation and service flexibility while managing complexity through a dedicated coordination mechanism.
3Ease of operation
If floor control is implemented using RTCP and dedicated unicast connection, then floor control functionality is achieved, but system extension and flexible service implementation are limited
Solution Approach 1:
The patent implements a universal floor control mechanism that works across multiple planes and service types. The floor control function is designed to be plane-agnostic, supporting both control plane and media plane operations, and can be applied to various PoC service scenarios including group calls, point-to-point calls, and broadcast services. This multi-functional design enables system extension while maintaining ease of floor control operation.

AI summary
Embodiments of the present invention provide a floor control method and apparatus, so as to resolve a prior-art problem: a control plane and a media plane of a PoC service are not separated, and this causes difficulty in subsequent technology evolution and is not conducive to either flexible implementation of services or system extension; and there is no detailed floor control procedure after the control plane and the media plane are separated. The method includes: receiving, by a media resource function entity, a first floor application message sent by UE; generating, by the media resource function entity, a second floor application message according to the first floor application message; sending, by the media resource function entity, the second floor application message to an MCPTT server; receiving, by the media resource function entity, a first floor grant message that is in response to the second floor application message and that is sent by the MCPTT server; generating, by the media resource function entity, a second floor grant message according to the first floor grant message; and sending, by the media resource function entity, the second floor grant message to the UE.
