Methods and apparatus for virtual soft handoff

摘要

In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive at a tunnel server, a data unit addressed to a communication device, and define, a first instance of the data unit and a second instance of the data unit. The first instance of the data unit is sent to the communication device via a first tunnel defined between at least the tunnel server and a first base station associated with a first network. The second instance of the data unit is sent to the communication device via a second tunnel defined between at least the tunnel server and a second base station associated with a second network. The second instance of the data unit is dropped by the communication device when the first instance of the data unit is received before the second instance of the data unit.

1. A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code comprising instructions to cause the processor to:
receive, at a tunnel server, a first data unit addressed to a communication device, the first data unit having a first data type; define, based on the first data unit, a first instance of the first data unit and a second instance of the first data unit; send the first instance of the first data unit to the communication device via a first tunnel defined between at least the tunnel server and a first base station associated with a first network and operatively coupled to the communication device; send the second instance of the first data unit to the communication device via a second tunnel defined between at least the tunnel server and a second base station associated with a second network different from the first network and operatively coupled to the communication device resulting in the communication device dropping the second instance of the first data unit when the first instance of the first data unit is received by the communication device prior to the second instance of the first data unit; receive, at the tunnel server, a second data unit addressed to the communication device, the second data unit having a second data type different from the first data type; define, based on the second data unit, a first instance of the second data unit and a second instance of the second data unit; send the first instance of the second data unit to the communication device via the first tunnel; and send the second instance of the second data unit to the communication device via the second tunnel.
