Embodiment Construction

[0017] Features of modern TEs and DCDs have led to a growing need for certain client service interface features not easily found in the prior art. For example, to facilitate application client software implementation, it would be desirable to have a set of service commands defined for the client service interface independent of the particular technology used by the data communications device. Additionally, for flexible control, it would be desirable to have a communication channel between the computing device and the data communication device that can support simultaneous data and control sessions. Furthermore, it would be desirable to have a multiplexing protocol capable of simultaneously supporting multiple clients on a single or multiple computing devices to communicate with multiple services running on a single or multiple communication devices.

Abstract

An interface architecture and protocol are provided for transferring messages between a plurality of devices. The architecture provides the capability to generate a plurality of service messages according to a single message format, and to transfer the service messages between a plurality of control points (101, 102 and 103) or service entities (114 and 115) according to an efficient multiplexing protocol. The control points can be software applications or device drivers running on a terminal equipment device (118), and the service entities can be communication services such as network access services or device management services running on an attached data communication device (119) such as a modem or a cellular phone.

Description

[0001] Claim of priority under 35 U.S.C § 119 [0002] This patent application claims priority over Provisional Application No. 60 / 706,711, filed August 8, 2005, assigned to the assignee of this application, and expressly incorporated herein by reference middle. technical field [0003] The present invention relates to data processing in digital electronic devices, and more particularly to messaging between one or more application clients and one or more service entities. Background technique [0004] Modern computing devices, such as personal computers, laptop computers, and personal digital assistants, are often tethered to data communication devices, such as modems, that enable computing devices to communicate through interfaces including, for example, IEEE 802.11, Code Division Multiple address (CDMA), General Packet Radio Service (GPRS) or Universal Mobile Telecommunications System (UMTS). The operating system running on the computing device typically supports a soft...
