Abstract
The invention is related to a controller of a communication system, the controller comprising: means for determining user terminal time delay between delivery and acknowledgement of a transmission; means for conveying the user terminal time delay; means for calculating switching time delay; and means for transferring user terminal data conveyance to the handover target network controller at a moment based on the switching time delay.
Claims23
A method, comprising:
- determining user terminal time delay between delivery and acknowledgement of a transmission, in a handover source network controller;
- conveying the user terminal time delay to a handover target network controller;
- and
- transferring user terminal data conveyance to the handover target network controller based on the switching time delay.
An apparatus, comprising:
- a determiner configured to determine user terminal time delay between delivery and acknowledgement of a transmission;
- a conveyer configured to convey and receiving the user terminal time delay;
- and
- a transferor configured to transfer user terminal data conveyance to a handover target network controller based on the switching time delay.
A computer program embodied on a computer-readable medium, the computer program configured to control a processor to perform operations comprising:
- determining user terminal time delay between delivery and acknowledgement of a transmission, in a handover source network controller;
- conveying the user terminal time delay to a handover target network controller;
- and
- transferring user terminal data conveyance to the handover target network controller based on the switching time delay.
A system, comprising:
- a controller configured to,
- determine user terminal time delay between delivery and acknowledgement of a transmission;
- convey the user terminal time delay;
- calculate a switching time delay;
- and
- transfer user terminal data conveyance to a handover target network controller based on the switching time delay.
A method, comprising:
- receiving a user terminal time delay from a handover source network controller;
- calculating a switching time delay in the handover target network controller using the user terminal time delay;
- and
- transferring a user terminal data conveyance to the handover target network controller based on the switching time delay.
An apparatus, comprising:
- a receiver configured to receive a user terminal time delay from a handover source network controller;
- a calculator configured to calculate a switching time delay in the handover target network controller using the user terminal time delay;
- and
- a transferor configured to transfer a user terminal data conveyance to the handover target network controller based on the switching time delay.
A computer program embodied on a computer-readable medium, the computer program configured to control a processor to perform operations comprising:
- receiving a user terminal time delay from a handover source network controller;
- calculating a switching time delay in the handover target network controller using the user terminal time delay;
- and transferring a user terminal data conveyance to the handover target network controller based on the switching time delay.
