Access Network Device Paging Request Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing mobile communications networks, the voice service setup delay is prolonged due to serial processing in the access network-core network-access network manner, affecting user service experience.
Innovation Solution
An access network device that actively generates and sends a paging request to the called user equipment before receiving a paging message from the core network, sets up a signaling connection, and sends ringing information independently, thereby reducing the voice service setup delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If serial processing in access network-core network-access network manner is performed, then network control and coordination are maintained, but voice service setup delay is prolonged
Solution Approach 1:
The access network device performs preliminary actions by actively generating and sending a paging request to the called user equipment before receiving the paging message from the core network device. This preliminary action initiates the connection setup process in advance, reducing the overall voice service setup delay while maintaining network control through subsequent coordination with core network instructions.
2Speed
If the access network device waits for core network instructions, then network protocol compliance is ensured, but service setup speed is reduced
Solution Approach 1:
The access network device takes preliminary action by generating and sending the paging request before receiving core network instructions, thereby improving service setup speed. The device then receives and processes the core network's paging message and subsequent instructions to ensure protocol compliance, combining proactive speed improvement with reactive protocol adherence.
Solution Approach 2:
The access network device dynamically adjusts its operation mode: it proactively initiates paging requests when speed is critical, then transitions to a reactive mode to receive and process core network instructions for protocol compliance. This dynamic approach balances speed improvement with reliability maintenance based on the timing and nature of incoming instructions.

AI summary
Embodiments provide an access network device and a communication method. The access network device includes: a receiver, configured to receive a call request sent by a calling user equipment, where the call request carries a user communication identity of a called user equipment. The access network device also includes a processor, configured to generate a paging request based on the user communication identity before the receiver receives a paging message sent by a core network device, where the processor is further configured to set up a signaling connection to the called user equipment based on the paging request. The access network device also includes a sender, configured to send the paging request generated by the processor to the called user equipment.
