M2M Event Broadcasting via Base Station Resource Reservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine-to-machine communication systems, there is a lack of a method for a mobile station to effectively broadcast emergency or specific events to other mobile stations, such as car accidents or toll gate fee payments, which are not efficiently communicated in existing systems.
Innovation Solution
A method involving sending an event registration message to a base station, receiving reserved DL resource region information, and broadcasting the event to other mobile stations using a reserved resource region, which includes event type, signal strength, and broadcast period information, allowing for one-time or persistent broadcasting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a mobile station broadcasts event occurrence to other mobile stations, then situational awareness and response time are improved, but network resource consumption and system complexity increase
Solution Approach 1:
The base station acts as an intermediary that receives event registration messages from mobile stations, allocates downlink resource regions, and facilitates the broadcast of event occurrences to other mobile stations. This mediator approach enables efficient event dissemination without requiring direct complex peer-to-peer communication protocols between mobile stations.
Solution Approach 2:
Mobile stations perform preliminary action by sending event registration messages to the base station before actual event broadcast. The base station pre-allocates downlink resource regions in response to these registration messages, ensuring that when events occur, the mobile station can immediately broadcast using the pre-prepared resource allocation without delay.
2Reliability
If downlink resource region is reserved for event broadcast, then broadcast reliability is improved, but available network capacity decreases
Solution Approach 1:
The downlink resource region allocation is dynamic rather than static. The base station allocates resource regions based on actual event broadcast needs triggered by mobile station requests. The allocation can be adjusted based on event characteristics, broadcast scope, and network conditions, allowing the system to adapt resource distribution in real-time while maintaining broadcast reliability.
Solution Approach 2:
The patent applies local quality by allocating downlink resource regions specifically for event broadcast purposes rather than providing uniform resource distribution. The base station identifies and reserves specific time-frequency resources tailored to the broadcast requirement, ensuring reliable event dissemination while leaving other network resources available for regular communications.

AI summary
The present invention relates to a method for transmitting a broadcasting service in a system that supports machine to machine communications, the method comprising: transmitting an event registration message to a base station for the registration of an event at the time of occurrence; receiving from the base station an event registration response that contains information on a reserved downlink resource area in the base station to transmit the vent occurrence to other terminals; and broadcasting the event occurrence to the other terminals via the reserved downlink resource area.
