Abstract
In order to alleviate network congestion, replication of packets is performed after the packets are received over a wide-area network (250). In particular, a voice packet received from a particular remote unit (201) by a particular base station (211) will be replicated, once for each downlink replicator involved in the call. These voice packets will be transmitted over the wide-area network (250) and will be received by the downlink replicators, again replicated, and transmitted to the appropriate base stations (212-215) where they are provided to their respective remote units (202-206).
Claims16
A method comprising the steps of:
- obtaining a list of member remote units in a call;
- determining for each remote unit in the call, a RAN that contains the remote unit;
- selecting a plurality of replicators such that a single replicator is associated with each RAN;
- receiving a voice or data packet;
- performing a first replication on the packet to produce a first plurality of packets;
- transmitting the first plurality of packets over a network;
- performing a second replication of the first plurality of packets to produce a second plurality of packets;
- and
- transmitting the second plurality of packets to the at least one remote unit in the call in the RAN associated with the second replicator.
A method comprising the steps of:
- receiving a voice or data packet;
- determining where the packet originated;
- and
- replicating the packet a number of times, wherein the number of times the packet is replicated is based on where the packet originated.
An apparatus comprising:
- means for receiving a voice or data packet;
- means for determining where the packet originated;
- and
- means for replicating the packet a number of times, wherein the number of times the packet is replicated is based on where the packet originated.
An apparatus comprising:
- a controller having a voice or data packet as an input and outputting the packet to replication circuitry;
- and
- replication circuitry having the packet as an input and outputting a number of replicated packets, wherein the replicated packets are output to a plurality of replicators over a wide-area network, where they are again replicated and forwarded to remote units involved in a group call.
