Mobile Station CID Self-Generation to Reduce Handover Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, the process of handover between base stations causes a time delay due to the need for mobile stations to acquire new connection identifiers (CIDs) from the new base station, which results in inefficiencies and increased data transmission/reception overhead.
Innovation Solution
The method involves broadcasting a first set value and a second set value by the base station, allowing mobile stations to acquire basic and primary management CIDs by adding the set values, thereby eliminating the need for direct CID exchange and reducing handover delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile station acquires new CIDs from the target base station during handover, then the connection identification is updated correctly, but the handover process experiences time delay and increased overhead
Solution Approach 1:
The mobile station performs CID self-generation in advance by calculating the primary management CID using the basic CID and pre-configured set values before actual handover occurs. This preliminary CID preparation eliminates the need for time-consuming CID exchange during handover, thereby reducing handover delay while ensuring CID accuracy through deterministic calculation.
Solution Approach 2:
The mobile station autonomously generates its own primary management CID by applying a predetermined algorithm (adding the first set value to the basic CID) without requiring interaction with the target base station. This self-service approach reduces signaling overhead and eliminates the time delay associated with traditional CID assignment procedures.
2Reliability
If the base station directly assigns CIDs to mobile stations, then the CID management is centralized and controlled, but the signaling overhead and processing complexity increase
Solution Approach 1:
The mobile station autonomously generates both basic CID and primary management CID using predetermined set values and a standardized algorithm, eliminating the need for the base station to directly assign these CIDs. This self-service mechanism significantly reduces signaling overhead while maintaining CID management control through pre-configured parameters and deterministic generation rules.
Solution Approach 2:
The system transforms the CID assignment process from a centralized parameter distribution model to a distributed parameter generation model. By changing the management approach from direct assignment to algorithmic generation using pre-configured set values, the signaling overhead is reduced while maintaining control through standardized generation rules.

AI summary
A method and apparatus for transmitting/receiving a connection identification (CID) in a communication system is provided. Upon detecting a need for its handover, a mobile station (MS) transmits a handover request message to a first base station (BS) in communication with the MS. Upon receiving the handover request message, the first BS transmits at least one CID for connection setup to a second BS to which the MS will perform handover, to the MS along with a handover response message in response to the handover request message. The MS receives the CID through the handover response message.
