Embodiment Construction

[0025] The increased demand for wireless data transfer and the expansion of services available through wireless communication technologies has led to the development of specific data services. One such service is known as HDR. An example of an HDR type system is the one proposed in the "cdma2000 High Speed ​​Packet Data Air Interface Specification" known as the "HAI Specification" and "TIA / EIA / IS-856".

[0026] An HDR user station, referred to herein as an access terminal (AT), may be mobile or stationary, and may communicate with one or more HDR base stations, referred to herein as a modem pool transceiver (MPT). An access terminal transmits data packets to and receives data packets from an HDR base station controller, referred to herein as a modem pool controller (MPC), through one or more modem pool transceivers. Modem pool transceivers and modem pool controllers are part of a network called an access network. The access network transports data packets between multiple ac...

Abstract

This disclosure provides a method and apparatus for the communication of low delay data over multiple channels having different speed and latency and requiring a different amount of time to set up. In one embodiment, the transmitter removes duplicate data packets from a queue after a second channel, such as a dedicated channel is established. In an alternate embodiment, sequence numbers are assigned to data packets, allowing the receiver to identify duplicate packets and ignore the duplicates.

Description

[0001] Priority claims under 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 60 / 511,275, filed October 14, 2003, entitled "Method and Apparatus for Communication of Data Over Multiple Channels," which is assigned to the present assignee, which is expressly incorporated herein by reference. technical field [0003] The present invention relates generally to data packet communications, and more particularly to communications over multiple channels. Background technique [0004] Typically, wireless communication systems for packet data transfers have a type of channel that is established between a sender and a receiver when a packet is ready for transfer. This type of channel is used for signaling and control between the base station (BS) and mobile station (MS), but can also carry user or application data. Since the channel is shared among several receivers, the channel is typically slow, and transmissions on the channel are des...
