Wireless Device Status Update Before Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face inefficiencies when a device disconnects, leading to resource waste and burden on HLR and SS7 networks due to continuous querying for device status, as location and status information becomes unavailable upon disconnection.
Innovation Solution
A wireless communication device maintains device status information, encodes it into a bitstream protocol, and transmits an update status message before losing connection with a wireless access node, ensuring timely and efficient data transfer to interested parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication network periodically queries the HLR to determine whether the device has registered, then the network can obtain device status information, but HLR resources are wasted and the SS7 network is burdened
Solution Approach 1:
The device proactively sends a status message to the network before disconnecting, indicating its offline status in advance. This preliminary action eliminates the need for the network to continuously query the HLR after disconnection, as the network already knows the device is offline from the pre-sent status message.
Solution Approach 2:
The device extracts and transmits its status information directly to the network before disconnecting, removing the need for the network to extract this information through repeated HLR queries. The status information is taken out from the device's internal state and delivered to the network proactively.
2Reliability
If the communication network continuously queries for device status after disconnection, then the network can attempt to locate the device, but network operations become inefficient and resources are wasted
Solution Approach 1:
The device sends its status information to the network before disconnecting, providing advance notice of its offline state. This allows the network to stop location queries efficiently without continuously checking the HLR, as the pre-sent status message already indicates the device is unavailable.
Solution Approach 2:
The device serves the network by proactively providing its own status information, eliminating the need for the network to perform repeated status checks. The device essentially serves the network's information needs on its own initiative before disconnecting.
3Productivity
If the device does not transmit status information before disconnection, then the device can power off immediately, but the network loses device status information and must waste resources querying
Solution Approach 1:
The device transmits its status information to the network before powering off, ensuring the network receives the information in advance. This preliminary transmission of status data allows the device to power off immediately afterward without causing information loss or network resource waste.
Solution Approach 2:
The device maintains the continuity of useful action by sending status information right before disconnection, ensuring uninterrupted information flow to the network. This keeps the network informed of the device's status without delaying the device's power-off sequence.

AI summary
A wireless communication device comprises a processing system, a memory system, and a wireless communication transceiver. The processing system is configured to maintain device status information in the memory system of the wireless communication device, encode the device status information to generate an update status message in a bitstream protocol, and detect a condition of the wireless communication device which could impede a connection with a wireless access node. The wireless communication transceiver is configured to, in response to the processing system detecting the condition of the wireless communication device, transmit the update status message before the connection with the wireless access node is lost.
