## Title
Shortcut for establishing a communication channel with a remote device over a network

## Abstract

Two-way communication between a general purpose computing device, such as a PC, and a mobile terminal, such as a cell phone. The general device executes a conversation user interface through which a user enters a message. The message is sent to an intermediary communication service, such as a portal server, along with a mobile terminal identifier, such as a phone number. The intermediary service creates a mapping between the mobile identifier, a general device user identifier, and an extension to an intermediary device identifier, such as an extension to an SMS short code. The intermediary service sends the message to the mobile terminal along with the intermediary service identifier and the extension. The mobile device returns a response with the mobile identifier, the intermediary service identifier, and the extension. The intermediary service uses the mobile identifier and the extension to determine the general device user identifier and send the response.

## Background
FIELD OF THE INVENTION
The present invention relates generally to mobile communications, and more particularly, but not exclusively, to two-way communication between a general purpose computing device and a mobile terminal.
BACKGROUND OF THE INVENTION
Email is considered a store-and-forward technology in which a message is stored by a server of a network center and forwarded to a target device when the target device is powered and connected to a network such as the Internet. Email messages are usually not limited in length. Computer and Internet companies developed instant messaging (IM) to provide direct, two-way text and graphics messaging. Instant messaging is generally considered a distinctly Internet product, and also usually does not place any limit on the length of messages. Instant messages are generally not stored and forwarded like conventional email. Instead, instant messages are typically handled through a central server in a protocol that is usually separate from email or web traffic to provide direct communication between clients. Users typically run a resident client application that provides IM services.
Wireless phone companies developed short message service (SMS) to provide a text messaging compliment to voice communication services. SMS was generally designed for the thinner communication channel of the wireless environment. Message length is usually limited (typically 80 or 160 characters), and the receiver must have a compatible mobile phone. Messages are usually handled by a network center, since SMS is a store-and-forward technology. In the case of SMS, a message is temporarily stored by a server of the network center and forwarded to a mobile device when the mobile device is powered and connected to a network such as a cellular network.
Although SMS is considered a store-and-forward technology, SMS messages are delivered to the mobile client whenever the mobile device is powered and connected to the network, rather than when the user launches a client message service like email. Thus, SMS and IM systems allow users to send messages that are generally faster and more intrusive than email or other text messaging systems. Instead of waiting for the receiver to check a message center (mailbox), these messages are delivered whenever the receiver is accessible by a message server.
Instant wireless is a wireless version of instant text messaging in which information is being sent through wireless networks in real-time, rather than being handled through a store-and-forward mechanism. As indicated above, store-and-forward delivery is traditionally used in many email and batched transaction handling systems. Typically, a message is stored in a server and then after a pre-defined delay, it is processed and sent to the destination server where it is picked up by the recipient. Instant wireless may be considered a one-way, real-time, digital telephone message conversation (not voice) with an answering machine, using a wireless network. It is considered communication with an answering machine, because the recipient at his/her option may not respond instantly. Since the communication channel does not necessarily stay open between sender and recipient, instant wireless is generally not considered true two-way communication. However, instant wireless does send messages instantly, rather than wait for a batch to accumulate. A pre-requisite to instant wireless is that the destination device is turned on and connected through wireline or wireless connection. It generally takes less effort to write code for instant messaging than it is for store-and-forward messaging. It is also generally more efficient with regard to processing costs. However, instant wireless generally requires a more costly infrastructure.

Exemplary Logic
FIG. 4 is a flow diagram illustrating exemplary logic operations performed by a client, such as a general purpose PC. At an operation 102, a user starts a browser session with a network service such as a portal. For instance, the user may sign into the network service through a web page with a user ID and password. Starting the browser session also establishes a session ID to distinguish this communication session from other sessions that the user may have or establish with the network service. Multiple sessions might be desired to hold multiple conversations with various parties.
At an operation 104, the client displays a web page that enables the user to initiate a conversation with a mobile user. The web page may include a conversation button that enables the user to initiate a text or other conversation with another user. Alternatively, or in addition, the web page may include a list of other users that can be contacted, such as an online address book. A conversation button may be displayed next to each other user on the list, or the user may select a listed user's name or other identifier, such as a mobile phone number. Thus, initiating a conversation may be performed in multiple ways. At an operation 106, the client detects the user's selection of the conversation button, name, phone number, or the like. The client displays a conversation box at an operation 108. The conversation box may appear as a message entry box in a separate window, in a separate frame of the web page, in the same frame as the web page, or in other forms. Java, Javascript, dynamic hypertext markup language (DHTML), or other coding means can be used to implement the conversation box. The conversation box generally includes a send button and/or other controls.
The client user enters a message via the conversation box. The message can include text, emoticons, audio, and/or other forms of communication that are supported by the network service and/or a target mobile terminal. At an operation 110, the client detects that the user activated the send button, and communicates the message to the network service. The message may be communicated as a hypertext transfer protocol (HTTP) message, an instant message, a markup language form, or other format. The client also sends a mobile user identifier such as a cellular telephone number, a mobile identification number (MIN), or other means to identify the target mobile user. The mobile identifier may be typed into a field of the conversation box, selected from the list of mobile users, or otherwise provided. The client or the network service may optionally translate the entered message into a form that is supported by the target mobile terminal.
The network service communicates the message to the mobile user and awaits a response. If a response is returned, the response is communicated to the client at an operation 112. The client displays the response in the conversation box at an operation 114. The client also generally identifies the responder with the cellular telephone number, MIN, or other means to identify the responding mobile user. If the client user chooses to end the conversation, the client detects activation of a close button or other control at a decision operation 116. The client then closes the conversation box at an operation 118. However, if the user continues the conversation, control returns to operation 110 as the user sends another message.
FIG. 5 is a flow diagram illustrating exemplary logic operations performed by the network service, such as a portal server. At an operation 122, the network service responds to a request from the client to establish a communication session. The network service may authenticate and/or validate the client and/or user upon sign in. One or more web pages may be transmitted to the client browser automatically or upon request from the user. For example, the user may request a page comprising the user's online address book of contact information. The network service may also transmit a page that includes an applet or other code for the conversation box. Alternatively, the network service may transmit one or more separate modules of code to implement the conversation box.
At an operation 124, the network service receives a message and mobile user identifier from the client. The network service establishes a mapping between the client and the mobile user at an operation 126. In one embodiment, the mapping generally comprises a relationship between the client user ID, an SMS short code identifying a communication address of the network service, a short code extension number, and the mobile user identifier. The relationship can also include the session identifier or a separate relationship can be established to associate the mobile user with a certain communication session with the client. Table A illustrates sample elements of the relationship.

At an operation 128, the network service establishes communication with the mobile user terminal and sends the message to the mobile user at the mobile user ID number. The network service also sends the short code and extension. The message to the mobile user may be reformatted and/or sent via a difference communication protocol. For example, the message may be sent to the mobile user as an SMS message, a multi media service (MMS) message, an IM, a voice IM, a wireless application protocol (WAP) message, and the like. For discussion purposes, the embodiment described herein uses an SMS message.
If the mobile user sends a response to the SMS short code, the network service checks for the extension to the short code at an operation 130. The network service also detects the mobile user ID of the responding mobile terminal. At an operation 132, the network service consults the relationship mapping to determine the client user ID associated with the mobile user ID and extension. The network service, or a separate communication interface determines the corresponding session ID for the appropriate communication channel to the client. If necessary, the network service translates the response into a format that can be communicated to the client such as HTTP message, a markup language form element, an IM, and the like. The network service then sends the response message to the client at an operation 134 for display in the conversation box.
The above specification, examples, and data provide a complete description of the manufacture and use of the composition of the invention. For example, the network service can communicate act as an intermediary to a communication service, such as an SMS server, to provide the relationship mapping, translation, and/or other services. The network service, or another intermediary service can also be used to store, compared, filter, and otherwise preprocess presence information, communication modes, and messages. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
