Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paging technologies in cellular communication networks face challenges such as increased power consumption, potential page misses due to cell reselection and outdated location area information, and throughput losses in dual SIM dual standby devices, particularly due to the lack of standardized repetition patterns for paging.
Innovation Solution
A method for determining the number of page repetitions and time interval between repetitions through triggering a dummy page or disconnection in wireless communication devices, using a server-based paging pattern database to collect and update profiling data, allowing for flexible and reliable profiling under favorable conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a short paging cycle is used to increase paging reliability and reduce page miss probability, then the probability to miss a page is reduced, but power consumption increases and stand-by time decreases
Solution Approach 1:
The patent applies dynamics by making the paging cycle length adjustable rather than fixed. The system dynamically adapts the paging cycle based on device activity patterns, mobility state, and network conditions. This allows the network to use shorter paging cycles when reliability is critical (e.g., high mobility or important calls) and longer cycles when power consumption is the priority (e.g., stationary devices or low-activity periods), thus resolving the contradiction between reliability and energy consumption.
Solution Approach 2:
The patent changes the parameter of paging cycle length based on different conditions. By introducing multiple paging cycle configurations (e.g., short, medium, long cycles) and selecting appropriate cycles based on device state, mobility level, and service type, the system optimizes the trade-off between page miss probability and power consumption. This parameter adaptation allows the network to achieve high reliability when needed while minimizing energy consumption during normal operation.
2Reliability
If paging is repeated multiple times to prevent page misses during cell reselection and location updates, then page delivery reliability is improved, but network signaling overhead and resource consumption increase
Solution Approach 1:
The patent applies partial action by implementing selective paging repetition rather than universal repetition for all pages. The system determines the number of repetitions based on specific conditions such as device mobility state, service type, and historical paging success rate. This allows the network to apply full repetition only when necessary (e.g., for high-value calls or uncertain device location) while using single-page transmission for routine communications, thus reducing overall signaling overhead while maintaining adequate reliability.
Solution Approach 2:
The patent uses preliminary action by performing paging profiling and predicting optimal paging parameters before actual paging occurs. The system analyzes historical data, device behavior patterns, and network conditions to pre-determine the appropriate number of repetitions and timing for upcoming pages. This preliminary preparation allows the network to optimize page delivery reliability in advance while avoiding unnecessary repetitions, thereby reducing signaling overhead.
3Reliability
If DSDS device punctures ongoing connection to monitor paging for another SIM, then paging monitoring capability is improved, but throughput and connection quality deteriorate
Solution Approach 1:
The patent applies periodic action by implementing discontinuous reception (DRX) cycles for paging monitoring. Instead of continuously monitoring paging or frequently puncturing ongoing connections, the DSDS device uses periodic wake-up intervals to check for pages on the other SIM. This periodic monitoring approach reduces the frequency of puncturing events, thereby maintaining throughput and connection quality while still providing adequate paging detection capability for dual SIM operations.
Solution Approach 2:
The patent makes the paging monitoring behavior dynamic by adapting the monitoring frequency and puncturing timing based on the state of the ongoing connection and paging urgency. When the ongoing connection is active with high throughput requirements, the system reduces paging monitoring frequency or delays monitoring until connection gaps. When paging is urgent or the connection is already in a low-activity state, monitoring frequency increases. This dynamic adaptation resolves the contradiction between paging monitoring capability and throughput maintenance.

AI summary
A paging profiling method for determining a number of page repetition and a time interval between the page repetitions is disclosed. The method comprises triggering the paging profiling by causing a page relating to one or more wireless communication devices. In some embodiments the method may further comprise updating an entry of a paging pattern database based on the paging profiling, wherein the entry is associated with a geographical area in which the one or more wireless communication devices reside. The paging pattern database may, for example, be comprised in a server. In some embodiments, the method may also comprise detecting that the paging profiling is needed by detecting that the entry of the paging pattern database is not valid, and triggering the paging profiling may be enabled responsive to detecting that the paging profiling is needed. Corresponding paging profiling arrangement, computer program product, wireless communication device and server are also disclosed.
