  • Method and System for Implementing Inter-Access Networks Handoff in Active State in HRPD Network
    Publication number: 20110317668
    Abstract: A method and system for implementing an inter-Access Network (AN) handoff in an active state in a High Rate Packet Data (HRPD) Network are disclosed. The method includes determining that an inter-AN handoff operation is necessary and initiating a handoff procedure to perform the inter-AN handoff, sending data to be transmitted to an access terminal to the destination AN in advance in the handoff procedure, and then sending the access terminal the data to be transmitted to the access terminal by the source AN or the destination AN according to the result of the handoff procedure.

  • Method and system for implementing inter-access network handoff in active state in HRPD network
    Patent number: 8054801
    Abstract: A method and system for implementing an inter-Access Network (AN) handoff in an active state in a High Rate Packet Data (HRPD) Network. The method mainly includes determining that an inter-AN handoff operation is necessary and initiating a handoff procedure to perform the inter-AN handoff, sending data to be transmitted to an access terminal to the destination AN in advance in the handoff procedure, and then sending the access terminal the data to be transmitted to the access terminal by the source AN or the destination AN according to the result of the handoff procedure. With the method according to the present invention, the continuity of a service may be improved. Even if the inter-AN handoff procedure fails, the source PCF may send data information obtained upon the start of the handoff to the access terminal when the access terminal returns to the source AN since the source PCF may receive data from the PDSN throughout the handoff procedure. As a result, the continuity of a service may be improved.
