Broadcast System for Wireless Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face congestion and service delays due to the use of individual SMS or MMS messages carrying similar information to multiple devices, leading to inefficiencies and potential blocking of mobile services.
Innovation Solution
A wireless communication system incorporating a two-way communication system and a one-way broadcast system, where information gathering devices like traffic cameras transmit data to a network controller, which determines the best method for message delivery using either the cellular system or the broadcast system based on device location, allowing for efficient distribution of common information to multiple users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual SMS or MMS messages are used to deliver information to multiple communication devices, then information can be delivered to each device individually, but the wireless communication network becomes congested with multiple messages carrying substantially the same information, resulting in longer communication delays or blocking of mobile services
Solution Approach 1:
The patent merges multiple individual message transmissions into a single broadcast message that can be received by multiple devices simultaneously. The broadcast system consolidates the delivery of substantially the same information to multiple communication devices, eliminating the need for separate message transmissions to each device and thereby reducing network congestion while maintaining information delivery reliability.
Solution Approach 2:
The patent implements a universal broadcast system that can serve multiple communication devices simultaneously with a single transmission. The broadcast message is designed to be universally received by multiple devices within the broadcast area, allowing the system to perform the function of delivering information to multiple recipients through a single channel, thus improving network efficiency without sacrificing delivery reliability.
2Loss of information
If individual messages are transmitted to multiple devices, then each device receives the message individually, but this results in longer communication delays and potential blocking of mobile services
Solution Approach 1:
The patent employs preliminary action by establishing a broadcast system infrastructure in advance that is capable of delivering information to multiple devices simultaneously. The broadcast message is prepared and transmitted in a single action that reaches multiple devices at once, rather than sequentially sending individual messages. This preliminary setup and single-transmission approach eliminates the time delays associated with multiple individual message deliveries while ensuring complete information delivery to all recipients.

AI summary
A communication network (100) includes a two-way communication system (101) having a number of base stations (102-108) providing corresponding coverage areas (110-116) for one or more mobile terminals (148 and 150). In order to minimize congestion of the two-way communication system (101) a broadcast system (118) is included which allows for messages to be transmitted to the mobile terminals (148 and 150). Provision of such a broadcast system frees-up network resources that would otherwise be required to support the transmission of such messages. In one embodiment, the communication network (100) includes a number of information gathering devices such as traffic cameras (126-136) that collect information on traffic conditions within the communication network (100). By determining the location of the mobile terminals (148 and 150) and their intended journey routes, or based upon travel information previously provided to the network, the communication network (100) can transmit via the broadcast system (118) images of traffic conditions along one or more particular travel routes to the mobile terminals (148 and 150). The mobile terminals (148 and 150) include receiver sections for receiving both the messages transmitted by the two-way communication system (101) and the one-way broadcast system (118).
