Mobile Station Paging Block Index Allocation for Dual SIM Power Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current resource allocation mechanisms in mobile communication networks inefficiently manage paging resources for mobile stations with multiple subscriber identities, leading to higher power consumption and reduced standby time due to independent resource allocation and unnecessary monitoring of multiple paging blocks.
Innovation Solution
A method and apparatus for a mobile station with multiple subscriber identities, where the communication network allocates the same paging block index for both subscriber identities, allowing the mobile station to receive paging messages at a single block, thereby reducing power consumption and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network allocates independent paging resources for each subscriber identity, then each subscriber identity can be paged independently, but the mobile station must monitor multiple paging blocks resulting in higher power consumption and reduced standby time
Solution Approach 1:
The patent merges the paging resources of multiple subscriber identities by allocating the same paging block index to multiple IMSIs. The mobile station monitors only one paging block for all its subscriber identities, combining what were previously separate monitoring tasks into a single operation, thereby reducing power consumption while maintaining the ability to page any subscriber identity independently
2Reliability
If the mobile station monitors multiple paging blocks for multiple subscriber identities, then no paging message is missed, but the standby time is shortened due to higher power consumption
Solution Approach 1:
The patent combines multiple paging block monitoring tasks into a single monitoring task by allocating the same paging block index to multiple subscriber identities. The mobile station monitors one paging block that contains paging messages for all its IMSIs, reducing power consumption and extending standby time while ensuring no paging messages are missed
3Ease of operation
If the network allocates separate paging blocks for each subscriber identity, then paging messages can be sent to specific subscriber identities, but network resources are repeatedly occupied by a single mobile station
Solution Approach 1:
The patent merges paging resources by allocating the same paging block index to multiple subscriber identities of the same mobile station. This allows the network to page any specific subscriber identity within that single paging block while reducing the total number of paging blocks needed, thereby improving network resource utilization while maintaining paging addressability
Solution Approach 2:
The patent makes a single paging block serve multiple functions by enabling it to contain paging messages for multiple subscriber identities. This multi-functional paging block can address different IMSIs simultaneously, improving network efficiency while preserving the ability to page specific subscriber identities

AI summary
A communication method for a mobile station communicating with a communication network and an associated mobile station are provided, wherein the mobile station has a first subscriber identity and a second subscriber identity. The method includes: sending a connection setup request for registration of the first subscriber identity; sending a connection setup request for registration of the second subscriber identity; and receiving paging messages targeted at either the first subscriber identity or the second subscriber identity at paging blocks with the same block index.
