Grouped Paging Message Structure for Mobile Unit Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face bandwidth constraints in paging channels due to high consumption by services like SMS and voice mail notifications, leading to inefficiencies in paging multiple mobile units simultaneously, which can increase latency and affect battery life.
Innovation Solution
The method involves deriving a mobile unit group identifier (MUGI) by combining individual mobile unit identifiers and using this combined identifier for signaling, allowing multiple mobile units to be paged in a single frame, thereby optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple mobile units are paged using traditional separate paging messages, then each mobile unit can be individually notified, but the paging channel bandwidth is exceeded and latency increases
Solution Approach 1:
The patent combines multiple individual paging messages into a single grouped paging message that contains multiple mobile unit identifiers. This merging approach allows the network to page multiple mobile units simultaneously within a single paging channel transmission, increasing the quantity of mobile units that can be notified without exceeding bandwidth constraints or increasing latency.
2Quantity of substance
If two-frame GPMs are used to pack multiple pages, then more mobile units can be paged, but reliability and battery life deteriorate
Solution Approach 1:
The patent segments the paging message structure by introducing a dedicated mobile unit identifier field within the grouped paging message. This segmentation allows each mobile unit's identifier to be clearly delimited and easily processable, maintaining high reliability even when multiple mobile units are packed into a single message frame.
3Adaptability or versatility
If SMS and voice mail notifications consume PCH bandwidth, then existing services are maintained, but bandwidth for new services is reduced
Solution Approach 1:
The patent creates a universal grouped paging message structure that can serve multiple functions: it can page individual mobile units, group multiple mobile units together, and accommodate various service types including SMS, voice mail, and emerging services like push-to-talk. This multi-functional approach allows the system to maintain existing services while creating bandwidth efficiency for new services.

AI summary
Various embodiments are described for signaling an ad-hoc group of mobile units (MUs). The ad-hoc group may be a group of MUs for which signaling awaits transmission via a wireless communication resource (111). Signaling such a group involves deriving a mobile unit group identifier (MUGI) by combining individual mobile unit identifiers (MUIs) of the targeted ad-hoc group. The individual MUIs are either an identifier of each MU or derived from an identifier of each MU. The derived MUGI is then included in combined signaling that is transmitted (by RAN 121, e.g.) via the wireless communication resource. A receiving MU (101) determines whether the MUGI could have been derived from its MUI in combination with at least one other MU's MUI. When it determines that the MUGI could have been derived from its MUI, the receiving MU processes the signaling as directed to itself.
