Abstract:
1. A method for controlling communications to an access terminal, comprising: applying a first treatment to a packet flow and transmitting the first treated packet flow to a first base station for transmission over an air interface to the access terminal, wherein the first treatment is selected based on a first radio technology implemented by the first base station; and applying a second treatment to a duplicate of the packet flow and transmitting the treated duplicate packet flow to a second base station for transmission over the air interface to the access terminal during a hand off period in which the access terminal is handing off from the first base station to the second base station, and wherein transmission of the first treated packet flow to the first base station occurs concurrently with transmission of the treated duplicate packet flow to the second base station, and wherein the second treatment is selected based on a second radio technology implemented by the second base station; and wherein the first and second treatments are maintained in a data structure in a router, wherein the data structure indicates a mapping between the first and second treatments and information in the packet flow, and wherein applying the first treatment to the packet flow comprises selecting the first treatment using information in the packet flow and the data structure.
