MME E-SMLC Locating Identifier Allocation for Accurate Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile locating schemes lack a method to ensure correct delivery of locating information, affecting the accuracy and improvement of locating technology.
Innovation Solution
The proposed solution involves the MME allocating a locating identifier and a relationship identifier, which are transmitted and used to ensure accurate communication of locating information between the MME, E-SMLC, and UE, facilitating correct delivery and improving locating accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locating schemes are used, then the locating service can be provided, but the correct delivery of locating information cannot be ensured
Solution Approach 1:
The patent introduces a locating identifier as an intermediary element that mediates the communication between network elements (MME, E-SMLC, eNodeB) and UE. This identifier acts as a unique key that ensures locating information is correctly associated with the corresponding UE context throughout the locating process, preventing information delivery errors.
Solution Approach 2:
The patent segments the locating information by introducing distinct identifiers: a locating identifier for the UE context and a relationship identifier for the locating session. This segmentation allows each component of the locating system to handle specific identifier types, ensuring that locating information is correctly routed and delivered without confusion between different UEs or sessions.
2Reliability
If no identifier allocation mechanism is implemented, then the system structure remains simple, but locating information cannot be correctly associated with UE context
Solution Approach 1:
The patent implements preliminary action by having the MME allocate a locating identifier to the UE context before the actual locating process begins. This pre-allocation ensures that when locating information needs to be delivered or associated with a UE, the identifier is already in place, eliminating the need for complex real-time identification mechanisms during the locating execution phase.
Solution Approach 2:
The MME performs self-service by automatically allocating and managing the locating identifier and relationship identifier without requiring external intervention. The MME maintains the mapping between these identifiers and the UE context internally, reducing the need for complex inter-node communication and identifier management protocols.

AI summary
The present invention discloses a locating method, apparatus and system, and the method comprises the following steps: a Mobility Management Entity (MME) receives a locating service request, selects an Evolved Service Mobile Location Center (E-SMLC), and transmits the locating service request including a locating identifier to the selected E-SMLC; the MME receives a User Equipment (UE) specific message including the locating identifier transmitted by the E-SMLC, and communicates the locating information with the E-SMLC using the locating identifier. The embodiments of the present invention can ensure the correct delivery of the locating information, and further improve the correctness of the locating technology.
