Transporting call data via a packet data network

摘要

Transporting call data is disclosed. A first call data associated with a first communication session and a second call data associated with a second communication session are received. The first call data and the second call data are bundled into a single data packet for transport over a packet data network.

主权项

1. A method of transporting call data, comprising:
receiving, at a first base transceiver station of a plurality of base transceiver stations, a first call data associated with a first communication session and a second call data associated with a second communication session; and bundling, at the first base transceiver station, the first call data and the second call data into a single real-time transport protocol (RTP) data packet for transport over a packet data network to an aggregation gateway (AGW), wherein the first call data is a late arriving call data that should have been included in a previously bundled data packet, and the first call data is bundled in the single RTP data packet after it is determined that the first call data is not late by a period that exceeds a prescribed threshold, wherein the first base transceiver station registers over the packet data network with a registration server before communicating with the AGW, wherein the registration server provides the first base transceiver station with keys for use in secure communications and an address of the AGW, wherein the AGW is connected, to a base station controller (BSC) in a mobile cellular network, wherein the AGW aggregates communications from the plurality of base transceiver stations and sends the aggregated communications to the BSC, and wherein the AGW presents the plurality of base transceiver stations as a single logical base transceiver station to the BSC.
