A switch (101) performs distribution functions by distributing packets to base stations that were most recently heard from. More particularly, as a gateway (115) provides frames to the switch (101), the switch (101) distributes the frames to all base stations in communication with a remote unit (113). In order to determine the plurality of base stations requiring the frames, an identification of base stations (on a per-call basis) currently backhauling data to the switch (101) for the call is maintained. The switch (101) then distributes frames received from the gateway (115) to those base stations currently providing uplink frames to the switch (101) for the particular call.

[ What is claimed is:] [1.] A method for identifying base stations for distribution of downlink data within a communication system, the method comprising the steps of:receiving, from a base station, a first packet that is to be routed to a selection function;determining a call identification and a base station identification from the first packet;determining a current time the first packet was received;storing the call identification, the base station identification, and the current time the first packet was received in a buffer;receiving a second packet that is to be distributed to a plurality of base stations involved in a call;analyzing the buffer to determine base stations existing on the buffer identified with the call; anddistributing the second packet to the base stations existing on the buffer identified with the call wherein base stations existing on the buffer are those who have transmitted packets to the distribution function within a predetermined time period.
