Intra-cell Peer-to-Peer Communication via CID Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for handling intra-cell communication between mobile stations associated with the same base station or relay station result in unnecessary delays and resource wastage, as they rely on base station controllers or gateway servers without considering the direct association between the stations.
Innovation Solution
Implementing a CID mapping table within network transceivers, such as base stations or relay stations, to identify and manage communications between mobile stations, enabling direct peer-to-peer communication by maintaining connection information and using security associations to encrypt and decrypt data units, thereby facilitating efficient data forwarding.

Engineering Contradiction Analysis
1Loss of time
If conventional methods using base station controllers or gateway servers are used to handle intra-cell communication, then communication between mobile stations can be established, but unnecessary delays and resource wastage occur
Solution Approach 1:
The patent extracts the intra-cell communication handling function from the base station controller and gateway server, allowing the base station to directly manage communications between mobile stations in the same cell. This removes unnecessary intermediate processing steps and reduces communication delay while maintaining proper routing control.
Solution Approach 2:
The patent introduces a CID mapping table as an intermediary data structure at the base station that directly maps source and destination mobile station identifiers to corresponding connection identifiers. This enables the base station to efficiently route intra-cell communications without involving higher-level controllers, reducing both delay and path complexity.
2Productivity
If base station controllers or gateway servers are used for intra-cell communication, then routing can be performed, but resource wastage occurs due to unnecessary involvement of additional network elements
Solution Approach 1:
The patent extracts the routing function for intra-cell communications from the base station controller and gateway server, consolidating this functionality at the base station level. This eliminates unnecessary resource consumption by additional network elements while maintaining proper routing capabilities through the CID mapping table.
Solution Approach 2:
The patent applies local quality by enabling the base station to independently handle intra-cell routing without involving higher-level controllers. The CID mapping table is maintained locally at the base station, allowing it to efficiently route communications between mobile stations in the same cell using only local information, thereby improving resource efficiency.
3Productivity
If direct peer-to-peer communication is enabled at the base station, then communication efficiency is improved, but additional functionality and complexity are required at the base station
Solution Approach 1:
The patent applies preliminary action by pre-establishing the CID mapping table at the base station that contains all necessary routing information for intra-cell communications. This mapping table is maintained in advance, allowing the base station to efficiently route communications without requiring complex real-time processing or additional functionality during actual data transmission.
Data Source
AI summary
Methods and systems for providing efficient communications between two mobile stations served by the same base station or relay station are provided. A base station maintains information identifying which mobile stations it is serving. When a connection is set up between two mobile stations, if they are both being served by the same base station, the base station forwards traffic directly between the two mobile stations without forwarding it on to higher level network entities.
