SIP Registration Factor for Selective Multi-Device Alerting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, managing multiple device registrations with shared identities and multiple identities services poses challenges, particularly in ensuring that users can control which device receives notifications and calls, especially when devices have overlapping or shared identities.
Innovation Solution
Implementing a factor for multiple device registrations that involves determining a factor based on registrations performed by different devices and using session initiation protocol messages to establish data sessions, allowing users to manage which device is alerted for calls or notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are linked together with shared identities to enable flexible device management, then device versatility and user convenience are improved, but it becomes difficult to control which specific device receives notifications and calls
Solution Approach 1:
The patent applies preliminary action by establishing registration information for multiple devices with shared identities before communication sessions are initiated. The network device stores registration data indicating which devices are currently registered with shared identities, allowing the system to determine the appropriate factor (q-value) in advance based on pre-stored device capability information and registration status, rather than making this determination reactively during each communication session
Solution Approach 2:
The patent implements feedback by using the determined factor (q-value) to influence subsequent session initiation protocol messages. The network device sends the factor to the session initiation device, which then uses this feedback to adjust its device selection behavior. This creates a closed-loop control system where registration information feeds into factor determination, which in turn guides device selection in ongoing communications
2Ease of operation
If the network tracks multiple device registrations to enable selective alerting, then user control over device interactions is improved, but network device complexity and processing requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the complex task of multi-device management into distinct functional components: (1) registration management, where the network device stores registration information for multiple devices with shared identities; (2) factor determination, where the network device calculates the appropriate q-value based on registration status and device capabilities; and (3) session initiation, where the factor is communicated to guide device selection. This segmentation allows each component to remain relatively simple while collectively solving the complex problem of selective device alerting
3Adaptability or versatility
If devices with shared identities can be freely registered and unregistered, then device adaptability is improved, but it becomes challenging to maintain accurate registration status information
Solution Approach 1:
The patent implements feedback mechanisms where the network device continuously maintains and updates registration information for multiple devices with shared identities. When devices register or unregister, the network device receives notifications and updates its stored registration status. This feedback loop ensures that the registration information remains accurate and current, allowing the system to reliably determine which devices are currently active and should receive communications
Solution Approach 2:
The patent applies self-service by having devices automatically send registration and unregistration notifications to the network device. When a device registers with a shared identity, it autonomously informs the network device, which then updates its records. Similarly, when devices unregister, they self-report this status change. This eliminates the need for manual tracking and ensures the network device maintains accurate registration information through device-initiated updates
Data Source
AI summary
Apparatuses, methods, and systems are disclosed for a factor for multiple device registrations. One method includes receiving, at a network device from a first device, a first session initiation protocol message including an identity for establishing a data session. The method includes determining a factor based on a first registration performed by a second device and a second registration performed by a third device. The method includes transmitting a second session initiation protocol message including the identity and the factor to the second device. The method includes establishing the data session between the first device and the second device. The identity is: registered for the first registration; registered for the second registration; not registered for the first registration; not registered for the second registration; or some combination thereof.
