Dynamic MSISDN Allocation for Wireless Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network systems face inefficiencies when assigning and managing limited Mobile Subscriber ISDN (MSISDN) numbers for wireless devices that require occasional access, as permanent assignments can lead to resource wastage and inefficiencies, especially for non-mobile devices that only intermittently need to connect.
Innovation Solution
A method and detection device that allow occasional access by authenticating wireless devices without communication with an Authentication Center (AUC) or Home Location Register (HLR), assigning MSISDN temporarily, and deprovisioning it after use, enabling the same MSISDN to be reused by other devices, with the detection device managing multiple wireless devices and third-party data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanent MSISDN is assigned to each wireless device, then the device can reliably access the wireless network, but the limited number of MSISDNs is wasted when devices only need intermittent access
Solution Approach 1:
The patent implements dynamic MSISDN assignment where the MSISDN is temporarily allocated to wireless devices only when they need to access the network, and released back to the pool after use. This dynamic allocation allows the same MSISDN to be reused by multiple devices over time, eliminating the waste of permanent assignments while ensuring reliable access when needed.
Solution Approach 2:
The system recovers MSISDN numbers from devices that have completed their network access tasks and returns them to the available pool for reuse. This recovery mechanism ensures that limited MSISDN resources are continuously utilized by active devices rather than being permanently tied to inactive ones.
2Loss of substance
If MSISDNs are temporarily assigned and reused, then resource efficiency is improved, but the complexity of managing MSISDN allocation and deprovisioning increases
Solution Approach 1:
The detection device serves as an intermediary between wireless devices and the core network elements (AUC, HLR, VLR). It manages the temporary MSISDN assignment process, handles authentication requests, and coordinates deprovisioning operations. This intermediary approach centralizes the complexity of MSISDN management in a dedicated component rather than distributing it across multiple network elements.
Solution Approach 2:
The system enables automated MSISDN allocation and deprovisioning through machine-to-machine communication. The detection device automatically assigns MSISDNs to devices that request network access, performs authentication without human intervention, and releases MSISDNs after use, eliminating the need for manual management of temporary assignments.
3Speed
If authentication is performed without AUC and HLR communication, then the access speed is improved for intermittent devices, but the security verification process is simplified
Solution Approach 1:
The detection device performs preliminary authentication verification by checking the device's IMSI against a local blacklist or allowed list before initiating full authentication protocols. This preliminary check quickly identifies devices that should be rejected or granted immediate access, reducing the need for lengthy authentication sequences with AUC and HLR for routine operations.

AI summary
Various arrangements for permitting a wireless device occasional access to a wireless network are described. Some arrangements for assigning a single MSISDN to multiple wireless devices are described. In such arrangements, the wireless devices may be associated with different visitor location registers. In some arrangements, a wireless device-initiated bearer service is initiated based on input from a remote system. In some arrangements, a wireless device is authenticated based on whether data needs to be sent to and/or received from the wireless device.
