APPARATUS AND METHOD FOR SUPPORTING HANDOVER IN A WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18330744 titled 'APPARATUS AND METHOD FOR SUPPORTING HANDOVER IN A WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The patent application relates to a communication system that supports higher data rates beyond 4G LTE.
- The invention provides a method for supporting handover between base stations in this communication system.
- The source base station informs the core network if a direct data forwarding path is available.
- The core network decides whether to use direct or indirect data forwarding.
- The core network then informs the target base station about the chosen data forwarding method.
- The target base station allocates data forwarding tunnel information based on this information.
- The target base station transmits the allocated data forwarding tunnel information to the core network.
- The core network informs the source base station about the data forwarding tunnel information.
- This method ensures different data forwarding methods are supported to prevent data loss and maintain service continuity.
Original Abstract Submitted
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention provides a method for supporting handover, comprising the steps of: informing, by a source base station, a core network whether a direct data forwarding path is available; deciding, by the core network, whether to use direct data forwarding or indirect data forwarding; informing, by the core network, a target base station of information about the direct data forwarding or indirect data forwarding; allocating, by the target base station, data forwarding tunnel information, the target base station allocating the data forwarding tunnel information according to the received information about the direct data forwarding or indirect data forwarding; transmitting, by the target base station, the allocated data forwarding tunnel information to the core network; and informing, by the core network, the source base station of the data forwarding tunnel information. With the present invention, different data forwarding methods are supported to prevent data loss and ensure service continuity.
