IMS Registration Validation for Authorized Service Enablement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Misalignment between in-device settings and network subscriber account provisioning leads to unsupported service requests from communication devices, wasting network resources and potentially causing system overload, especially in large service provider networks with devices from various vendors.
Innovation Solution
A method and apparatus that utilize the IMS registration process to validate and adjust application features enabled in communication devices, using a network server to provide a list of authorized services, allowing devices to compare and reconfigure their settings to match network support, thereby preventing unsupported feature requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual auditing and monitoring processes are used to detect misaligned device settings, then service providers can identify unsupported feature requests, but the process is time-consuming and reactive, significantly impacting subscriber services or network performance before detection
Solution Approach 1:
The patent applies preliminary action by validating device feature settings during the initial IMS registration process, before the device can request unsupported services. The network device obtains the list of enabled services from the HSS and compares it with the device's requested features during registration, preventing misalignment issues before they impact network performance or subscriber services.
2Adaptability or versatility
If devices are configured with all possible application features enabled, then devices have maximum versatility and functionality, but the network receives requests for unsupported services, wasting network resources and potentially causing system overload
Solution Approach 1:
The patent implements feedback by having the network device provide the validated list of enabled services back to the communication device during the IMS registration process. The device uses this feedback information to adjust its feature requests, ensuring it only requests services that are both locally enabled and network-supported, thereby eliminating wasted network resources while maintaining maximum possible functionality.
Solution Approach 2:
The patent applies preliminary anti-action by preventing devices from requesting unsupported services in the first place. During IMS registration, the network device compares the device's requested features against the HSS-provisioned enabled services list and only allows registration for supported features, thereby preemptively blocking resource-wasting requests before they occur.
3Reliability
If network operators rely on monitoring error response signatures and call detailed records to detect misalignment, then they can identify problematic devices, but these reactive processes waste significant network resources and can be exploited by malicious actors to cause system overload
Solution Approach 1:
The patent applies preliminary action by validating device feature configurations during the initial IMS registration process, before devices can generate error responses or consume network resources through unsupported service requests. The network device obtains enabled services from HSS and enforces compliance during registration, preventing resource waste and eliminating the need for reactive monitoring of error signatures and call detailed records.
Data Source
AI summary
Aspects of the subject disclosure may include, for example, receiving, over a network, a registration request (e.g., an IMS registration request) from a communication device; obtaining, by the network device over the network from a network server, information indicating enabled services associated with the communication device; and providing, by the network device over the network, a request successful message to the communication device, where the request successful message includes the information indicating the enabled services. Other embodiments are disclosed.
