Enhanced Service Area Identification for Precise Enterprise Location Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for identifying specific location areas in mobile communication networks face challenges such as large tracking areas that are difficult to match with actual locations, leading to increased signaling overheads due to the transmission of multiple cell identities, and frequent adjustments requiring additional signaling.
Innovation Solution
Introduce the concept of enhanced service areas, identified by an enterprise differentiator identifier and optional sub-area identities, allowing terminals to determine access based on matching these identifiers, reducing the need for transmitting multiple cell or tracking area identities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If tracking area identity is used to identify location area, then the location area coverage is large, but it is difficult to match the specific location area
Solution Approach 1:
The patent segments the location identification into two levels: tracking area identity (TAI) for broad coverage areas and cell identity (CI) for precise location identification. This hierarchical segmentation allows the system to maintain large coverage areas while achieving precise location matching by combining both identification levels.
2Measurement precision
If cell identity is used to define location area, then the location precision is improved, but a large quantity of cell identities need to be sent to terminal device, increasing signaling overheads
Solution Approach 1:
The patent merges multiple cell identities that belong to the same tracking area into a single location area identification unit. Instead of transmitting individual cell identities to the terminal device, the system transmits a consolidated location area identity that represents multiple cells, thereby reducing signaling overhead while maintaining location identification precision.
Solution Approach 2:
The patent creates a universal location area identity that can represent multiple cell identities within a tracking area. This universal identifier serves multiple functions: it identifies the tracking area, represents multiple cells, and reduces signaling requirements, making the system more efficient without sacrificing location precision.
3Adaptability or versatility
If tracking area or cell identities are frequently adjusted during network planning, then the network flexibility is improved, but additional signaling is required
Solution Approach 1:
The patent performs preliminary consolidation of cell identities into tracking area identities during network planning and configuration. By pre-grouping cells into tracking areas with unified identities, the system reduces the need for frequent signaling updates when network adjustments are made, as the consolidated identifiers remain stable even when individual cell configurations change.

AI summary
This application provides a communication method and apparatus. The method includes: A terminal device receives information about an enhanced service area allowed to be accessed, where the information about the enhanced service area allowed to be accessed includes information about one or more enhanced service areas; the terminal device receives information about a first enhanced service area corresponding to a first area from an access node after entering the first area; and the terminal device determines that the terminal device is allowed to access the first enhanced service area based on the information about the enhanced service area allowed to be accessed and the information about the first enhanced service area. In embodiments of this application, a network side only needs to send the information about the enhanced service area allowed to be accessed by the terminal device to the terminal device, and the enhanced service area can well match a coverage range of an enterprise. In addition, in embodiments of this application, overheads caused by sending the information about the enhanced service area to the terminal device are less than overheads caused by sending a cell identity to the terminal device.
