Network Controller Pre-Transmits Service Data for Roaming Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communications networks experience a relatively low service rate when users roam, as they require real-time extraction of service information from local networks, which is time-consuming and inefficient, especially for data-intensive services like video and images.
Innovation Solution
The method involves analyzing user data and network service information to predict the target network requirements and transmitting this information ahead of time to the target network, allowing it to prepare resources, thereby enabling rapid service provision when the access terminal connects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time extraction of service information is performed from local network when user roams, then service information can be obtained, but service rate becomes low and time consumption increases
Solution Approach 1:
The patent applies preliminary action by extracting and transmitting service information from the local network to the target network before the user actually roams. The source network controller extracts service information including user data and network service information, transmits it to the target network controller in advance, and stores it locally. When the user roams, the target network can immediately provide services using the pre-stored information, eliminating real-time extraction delays and significantly improving service rate.
2Loss of information

The source network controller extracts service information including user data and network service information, transmits it to the target network controller in advance, and stores it locally.

3Productivity
If network resources are prepared in advance for access terminal, then service rate improves, but network complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism - the service information database - that acts as a mediator between the source network and target network. The database stores pre-extracted service information and makes it available to the target network controller when needed. This intermediary approach simplifies the complexity by providing a standardized interface and centralized storage location, rather than requiring direct complex interactions between networks for each roaming event.

AI summary
The present invention provides a method, system, and network controller for network function customization. The method includes: obtaining target network information of a target network that is to be accessed by an access terminal; obtaining information about a current network used by the access terminal and user data access frequency information; obtaining, according to the information about the current network, the user data access frequency information, and the target network information, at least one type of information in user data and at least one type of information in network service information that are needed by the access terminal when the access terminal accesses the target network; and transmitting, before the access terminal moves into the target network, the at least one type of information in the user data and the at least one type of information in the network service information to the target network. In the foregoing technical solutions, network resources are prepared for an access terminal in advance, thereby resolving a technical problem that a communications network has a relatively low service rate in the prior art, and improving the service rate of the communications network.
