Broadcast Data Service Device Counting via Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current counting procedures for broadcast data services in wireless communication systems are inaccurate as they only measure devices in connected mode and require devices to expend radio resources by waking up during specific intervals to respond to counting requests, leading to inefficiencies.
Innovation Solution
Implementing registration-based counting methods where devices can report their status during registration or idle mode, allowing networks to determine the need for refined counting and enabling devices to switch to active mode only when necessary to respond to counting requests, thereby optimizing radio resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional counting procedures are used where devices respond to counting requests, then the base station can obtain device counts, but the counting accuracy is limited to connected mode devices only and radio resources are wasted
Solution Approach 1:
The patent applies preliminary action by having devices send registration requests before actual broadcast data reception. The base station counts these registration requests in advance to determine the number of interested devices, eliminating the need for subsequent counting requests and responses. This preliminary counting of registered devices provides accurate numbers while conserving radio resources that would otherwise be spent on counting procedures.
2Loss of information
If devices wake up during specific intervals to respond to counting requests, then counting data can be collected, but device power consumption increases and radio resources are expended
Solution Approach 1:
The patent implements self-service by having devices automatically send registration requests when they want to receive broadcast services, without needing to wake up for polling. The base station passively collects these self-initiated registration requests to obtain counting information. This eliminates the need for devices to expend energy waking up and responding to counting requests, while still gathering accurate counting data from all interested devices.
3Productivity
If registration-based counting is implemented, then the network can determine device counts efficiently, but additional registration signaling is required
Solution Approach 1:
The patent applies universality by making the registration request serve multiple functions simultaneously: it acts as both a service subscription indication (device wants broadcast data) and a counting response (device is present and interested). This multi-functionality eliminates the need for separate counting procedures, improving counting efficiency without adding significant complexity since the registration mechanism is already part of standard broadcast service procedures.

AI summary
Methods and apparatuses are provided that include counting devices for broadcast data services. The devices can be counted based on registrations received from the devices. This registration count can additionally or alternatively be used to determine whether further counting is desired. In addition, base stations can transmit counting requests to the devices using a paging message or other message such that idle mode devices can receive the counting requests. The idle mode devices can respond to the requests or send autonomous counting report by switching to an active mode for the purpose of responding or another purpose.
