Multi-band Information Element for Compressed Mode Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In telecommunications systems, particularly in UMTS, mobile devices face inefficiencies in communicating compressed mode requirements due to increased data volume, which hampers the effective use of limited communication bandwidth when supporting multiple frequency bands.
Innovation Solution
A method and apparatus that utilize a multi-band information element within the measurement capability message to efficiently convey compressed mode requirements, allowing devices to report the need for compressed mode across multiple frequency bands using a single Boolean expression, reducing data volume and streamlining communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If devices report compressed mode requirements for each frequency band separately, then the network can obtain detailed capability information, but the data volume increases and communication bandwidth is wasted
Solution Approach 1:
The patent combines multiple individual capability indicators for different frequency bands into a single multi-band information element. Instead of transmitting separate Boolean values for each band combination, the invention merges them into one compact data structure that conveys the same capability information with reduced data volume.
Solution Approach 2:
The multi-band information element serves multiple functions simultaneously: it indicates compressed mode capability across multiple frequency bands, applies to various measurement types (inter-frequency, intra-frequency, inter-RAT), and works for different band combinations. This universal element replaces multiple specialized indicators.
2Adaptability or versatility
If devices use traditional measurement capability messages, then compatibility with existing systems is maintained, but communication efficiency decreases due to larger data volume
Solution Approach 1:
The multi-band information element is nested within the existing measurement capability message structure. The new efficient encoding is embedded as part of the traditional message format, allowing the system to maintain compatibility with existing protocols while implementing improved data compression and transmission efficiency.
3Reliability
If detailed per-band compressed mode requirements are communicated, then network can optimize resource allocation, but limited communication bandwidth is consumed
Solution Approach 1:
The invention changes the parameter representation from individual per-band Boolean values to a compressed multi-band information element. This parameter transformation maintains the essential capability information needed for resource allocation optimization while significantly reducing the bandwidth consumption required to transmit the same information.
