Proximity Communication Service Identifier Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies require data transmission through mobile networks even for proximal devices, leading to increased delay and resource usage, and struggle to associate application layer identifiers with network layer identifiers for proximity communication services.
Innovation Solution
A method and device that allocate a proximity communication service identifier to UEs upon subscription, allowing for direct proximity communication by determining the service identifier from the request and implementing the service accordingly, thereby bypassing the need for network layer identification from application layer identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission through mobile network (serving eNB and core network) is used for proximal devices, then network control and resource management are maintained, but communication delay increases and network resource usage increases
Solution Approach 1:
The patent segments the communication path by introducing a direct device-to-device transmission channel that operates independently from the traditional core network path. This allows proximal devices to communicate directly while the network retains control through separate signaling channels, thus reducing delay without completely severing network oversight.
Solution Approach 2:
The patent introduces an intermediary mechanism where the network establishes and manages the direct communication link between devices through signaling messages, but actual data transmission occurs directly between devices. This intermediary approach maintains network control while enabling low-latency direct communication.
2Reliability
If data transmission through mobile network (serving eNB and core network) is used for proximal devices, then network control and resource management are maintained, but network resource usage increases
Solution Approach 1:
The patent segments the communication functions by separating control signaling (handled by the network) from data transmission (handled directly by devices). This segmentation allows the network to maintain control while devices independently manage data transmission, reducing overall network resource consumption.
Solution Approach 2:
The patent enables devices to self-serve by directly transmitting data to each other without network involvement in the actual data path. The network only provides initial setup and control, after which devices autonomously manage their communication, thereby reducing network resource usage.
3Productivity
If application layer identifiers are mapped to network layer identifiers for proximity communication, then direct communication between proximal devices is enabled, but device complexity increases
Solution Approach 1:
The patent introduces the network as an intermediary that manages the complex identifier mapping process. Instead of devices independently handling the complex task of mapping application layer identifiers to network layer identifiers, the network performs this function centrally, simplifying the device implementation while enabling direct communication.
Solution Approach 2:
The patent uses identifier copying mechanisms where the network layer identifier is derived or copied from the application layer identifier through standardized mapping rules. This copying approach simplifies the mapping process compared to creating entirely new identifiers, reducing device complexity while enabling direct communication.

AI summary
The present disclosure provides a method and a device for implementing a proximity communication service. The method includes steps of: receiving a request for the proximity communication service from a UE; in accordance with the request for the proximity communication service from the UE, determining a proximity communication service identifier obtained when the UE subscribes for the proximity communication service; and in accordance with the proximity communication service identifier of the UE, implementing the proximity communication service. According to the present disclosure, it is able to prevent the situation where the proximity communication service cannot be implemented when a UE's 3GPP network layer identifier cannot be determined in accordance with a UE's application layer identifier, thereby to implement the proximity communication service of the UE.
