F-CCCH Broadcast Message Transmission in Mobile Systems

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional mobile wireless communication systems are limited in transmitting broadcast messages, as they cannot utilize the Forward Common Control Channel (F-CCCH) for actual message transmission, relying solely on the Secondary Broadcast Control Channel (S-BCCH) and requiring Enhanced Broadcast Page information to be sent via F-CCCH.

Innovation Solution

A method where a base station determines the enablement of periodic enhanced broadcast paging and transmits broadcast messages directly via the F-CCCH, allowing for transmission in at least one slot of a broadcast paging cycle, eliminating the need for S-BCCH and enabling efficient message delivery to all mobile stations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If broadcast message is transmitted via S-BCCH only, then message transmission is possible, but transmission efficiency is reduced and system complexity increases

Engineering Contradiction:

Improvebroadcast message transmission efficiencyVSAvoidmessage transmission system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the broadcast message transmission function into the F-CCCH channel, which is already used for control information transmission. By combining the control information transmission and broadcast message transmission into a single channel (F-CCCH), the system eliminates the need for separate S-BCCH channel, thereby reducing system complexity while maintaining transmission efficiency

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The F-CCCH channel is given multi-functionality to serve both as a control information channel and as a broadcast message transmission channel. This universal usage of F-CCCH for multiple purposes eliminates the need for dedicated S-BCCH, reducing overall system complexity while improving transmission efficiency

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If Enhanced Broadcast Page information is transmitted via F-CCCH, then control information is provided, but actual broadcast message cannot be transmitted via F-CCCH

Engineering Contradiction:

Improvechannel utilization flexibilityVSAvoidtransmission channel structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the control information transmission (Enhanced Broadcast Page) and actual broadcast message transmission into the same F-CCCH channel. This merging eliminates the need for separate S-BCCH channel structure, reducing system complexity while enabling full utilization of F-CCCH for both control and data transmission

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The F-CCCH channel is enhanced to perform multiple functions: transmitting control information (Enhanced Broadcast Page) and transmitting actual broadcast messages. This multi-functional design increases channel utilization flexibility while simplifying the overall transmission channel structure by eliminating S-BCCH

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method of transmitting a broadcast message using a Forward Common Control Channel (F-CCCH) in a wireless communication system is disclosed. More specifically, a base station determines whether a periodic enhanced broadcast page is enabled or disabled, and then transmits at least one broadcast message via a first slot of a broadcast paging cycle of the F-CCCH if determined that the periodic enhanced broadcast page is enabled.
