Abstract

A system and method for enabling the use of popular serial networking application software (24) to transmit PPP packet data via a CDMA type subscriber device (30) to a network such as the internet (22). One or more reserved phone numbers is stored in memory (54) within the subscriber device. The networking application (24) is provided a telephone number to be dialed in order to make a connection to the internet. The telephone number provided to the networking application is compared to the stored reserved telephone numbers. If there is a match, the subscriber device (30) transmits a CONNECT signal back to the networking application and initiates a packet data call. If there is no match, the subscriber device (30) initiates an asynchronous data call.

Description

TRANSMISSION OF DATA PACKAGES ON CELLULAR TELEPHONE OF MULTIPLE ACCESS TYPE WITH CODE DIVISION FIELD OF THE INVENTION This invention relates to the transmission of PPP data packets from a network application computing program that runs on a host computer to a network such as the Internet and more particularly refers to the transmission of these data packages on a CDMA type cell phone (multiple access with code division).

BACKGROUND OF THE INVENTION It is considered common for a user to connect his computer to the Internet. A computer user may employ any of several popular, serial, network application software packets to make this connection, and send PPP data packets (from point-to-point protocol) to a attached device such as a modem. (The modem can also be integrated into the computer). Many of these popular, serial, network applications will not transmit their PPP data packets until they have received a signal (called the "CONNECT" signal) indicating that the attached device has dialed a requested telephone number and terminated the usual protocol of " link "with the corresponding remote modem (that is, the remote modem of the Internet service provider). Other network applications will transmit the PPP data packets if the user sets the command AT + CRM = 1. Once the AT + CRM command is established, it is set for all network applications hosted on that computer, and if a user you want to change from an asynchronous communication mode (where AT + CRM should be set to = 0) to a packet data mode (where AT + CRM should set = 1) the user should readjust the AT + CRM command each time change the modes. A CDMA-type cell phone does not dial a telephone number and does not perform the usual "link" protocol in order to establish a PPP data packet call. Therefore, the network application computing program will not receive a "CONNECT" signal and will not start the transmission of the PPP data packets, unless some additional action is taken such as the adjustment of the order AT + CRM = 1. In this way, there is a need for a simple and convenient procedure to induce a network application, which normally requires a "CONNECT" signal to transmit its PPP data packets when its connection to the Internet is going to be via a CDMA type device. such as a CDMA type cell phone. This procedure should not require the user to re-establish the AT + CRM command each time a mode change is desired.

SUMMARY OF THE INVENTION In order to induce the network application computing program to transmit its PPP data packets, the data qualified CDMA subscriber device (e.g., cellular telephone) monitors the order of telephone dialing sequence sent by the network application and compare this against a (a list of) number (s) of reserved phones. When the subscriber's device detects / receives a typical "AT" dial sequence order, the subscriber's device examines the telephone number contained within the dialing sequence, and compares it against the telephone number (s) ( s) reserved (s). If the telephone number contained within the dialing sequence is not one of the reserved numbers, the CDMA device will construct the usual asynchronous data call and transmit the call on the system. In response, the I F (intermixing function) will issue the expected "CONNECT" command back to the network application. Having received the expected "CONNECT" signal, the network application will then transmit synchronously in a normal manner. If the telephone number contained within the dialing sequence corresponds to a number in the reserved list, the CDMA subscriber's device does not construct a CDMA call in the synchronous format (ie, the synchronous service options 0x0004, 0x0005, 0x1005, 0x12 or 0x13). Instead, it constructs a data packet call (that is, packet service options 0x0007, 0x00015 or 0x1007) and simply transmits a "CONNECT" command back to the network application. This tricks the network application into believing that the CDMA device has connected almost instantaneously with a remote modem. The network application then transmits its PPP packets via the CDMA subscriber device. Other features and advantages of the invention will become readily apparent from the following detailed description of the invention and its various embodiments, from the claims and the accompanying drawings in which the details of the invention are fully and completely described as part of this specification.

Figure 2 illustrates a system for using a CDMA cellular telephone and a base station to connect a computer to the Internet using the CDMA asynchronous data service. Figure 3 is a system configured in accordance with the present invention to use a CDMA cellular telephone and the base station to connect a computer to the Internet using a CDMA data packet service.

DETAILED DESCRIPTION OF THE INVENTION The communication between a desktop or laptop computer 10 and that which has become commonly known as the Internet 22, can be easily achieved by means of a system such as that illustrated in Figure 1. A computer 10 it is connected over a public telephony line 12 and through the public telephony system 14 to the remote modem 16 of a provider 18 of the Internet service. The Internet service provider uses any acceptable communication route 20 to connect the computer 10 to the Internet 22. Usually a request for access to the Internet (or other "network") is initiated by the user of the computer through a computer. 24 pack of network application computing program. The computer user provides the network application computing program with the telephone number to be dialed in order to access the desired provider of Internet services. The user instructs the network application computing program 24 to access the Internet. The computer program 24 then passes the telephone number of the modem 16 of the Internet service provider to the modem 26 associated with the computer 10. The modem 26 may be integral with the computer or it may be a separate device connected to the computer by a means appropriate. The modem 26 then sends the appropriate signals, i.e., a dial sequence order including the telephone number of the destination modem 16, over a telephone line 12 through the public telephone system 14 to the modem 16. The modems 26 and 16 then they are coupled in the usual "link" protocol to establish the connection to the Internet service provider 18. Once the protocol is terminated and the connection is confirmed, the modem 26 sends a CONNECT signal back to the 24 count application program. Only after receipt of the CONNECT signal will the network application computing program 24 begin to transmit its PPP data packets through the system to the final destination within the Internet (or other network).

In today's fast-paced world, a computer user can be "continuously busy" using a laptop, and can not access a telephone line 12. In this case, a system such as that shown in Figure 2 for connecting the computer 10 to the Internet 22. The laptop is provided in a direct connection 28 of physical wire to a cellular phone 30 which is capable of the CDMA asynchronous data service. Although the computer 10 may have an integral modem 26, the modem is not connected to the cell phone. Actually, the cellular telephone 30 is directly connected to a data port of the computer 10 by the direct connection 28. The cellular phone 30 uses its antenna 32 to transmit data electromagnetically to the antenna 34 to a base station system 36. , associated which includes a base station 38 and the IWF 40. The base station system is connected to a modem 26 'which is analogous to the modem 26 of Figure 1. The modem 26' is connected (as the modem 26 was connected) to a physical telephone line 12. The rest of the route to the Internet 22, as shown in Figure 2, is the same as that shown in Figure 1. The operation of the system shown in Figure 2 is substantially the equivalent of the operation of the system of Figure 1. Figure 2, the cell phone 30, the base station system 36 and the modem 26 'serve only to access a physical telephone line 12. In other words, they function as a physical wire connection to the telephone line 12. The modem 26' and the modem 16 are coupled in the usual "link" protocol, and when the connection is established, the modem 26 'sends a CONNECT signal back through the system to the network application computing program 24, promoting the start of the transmission of your PPP data packets No data packets will be sent before receiving the CONNECT signal. The configuration of the system shown in Figure 2 is the typical configuration for asynchronous calls. The amount of time required for the modem 26 'to dial the remote modem 16 can be substantial. For example, it would not be unusual for the total time consumed by the placement of the telephone call and the termination of the "link" protocol to exceed 25 seconds. Air time on a cell phone is expensive and long delay is a substantial nuisance to many users. Figure 3 shows a communication system that includes a computer connected to the Internet via a cell phone capable of CDMA packet data service. For this system to work, the network application computing program must send PPP packets to the cell phone.

Some popular network application computing program packets will send PPP packets only after they give instructions to a linked modem 26 to dial to a remote modem and only after they have received a notification signal back (for example, a CONNECT signal). ) that the remote modem and the attached modem have terminated their "link" protocol. A CDMA telephone that wishes to use the packet data service will not use a modem and therefore this notification signal will not be received. However, the current standards of CDMA phones allow users to initiate the transmission of PPP data packets by setting the order AT + CRM = 1. But for many users, this is not a simple or convenient task. This invention makes it possible to use this network application computing program, popular in making the cell phone, upon receipt of a pre-selected "reserved" telephone number, return the CONNECT signal, thereby inducing the computer program to network application I sent PPP data packets. The lists of reserved telephone numbers can be pre-set by the telephone manufacturer or can be set by the user. The telephone number to be ordered from the network application computer program is also easily specified by the user through the user interface, and different telephone numbers can be specified for each network application compute program package, Hosted It is to be understood that while reference is made to "telephone number", the "telephone number" may be any desired combination of symbols and / or numbers, and therefore this "telephone number" will also generally refer to a "telephone number". data entry "several times in this specification. Before a user can instruct the computer application computing program 24 of the computer 10 to access the Internet, the user must first have provided the computer program 24 with the appropriate telephone number to be dialed. This is achieved by entering the telephone number in the network application computing program via its user interface. The network application computing program will then dial the specified phone number when instructed by the user to access the Internet. When the user instructs the network application computing program to connect, the network application computing program usually issues an ATD or ATDT command to the connected device (eg, a modem or cell phone). The computer program 24 then typically waits to receive a CONNECT signal (either in the result code format such as "CONNECT", "CONNECT 19200" and / or the elevation of the bearer detection pin). However, since the cell phone is not a modem and does not dial a telephone number and does not lead to any MODEM "link" protocol, the CONNECT signal will not be received back unless the user has taken the requested additional action to properly establish the AT + CRM order (which in general is not convenient to do). Therefore, the network application program will not begin transmitting its PPP data packets. The present invention allows the user to easily and conveniently instruct the system to configure a packet data call. The implementation of the present invention is best illustrated with reference to Figure 4. The user first programs the cellular phone 30 by entering one or more "reserved" telephone numbers into a memory register such as a look-up table 54 within the cell phone . Also stored in a memory register 56 inside the cell phone is the signal CONNECT. The "reserved" telephone number (s) can not be a real telephone number and can be a series of desired numbers and symbols. For example, the reserved telephone number can be # 777 or * 999. The user also provides the network application computing program with a data entry that functions as a telephone number to be dialed, when entering the data in register 50 (or 50 'or 50") specified by the respective network application computing program package, when the user instructs the network application computing program 24 to connect to the Internet, the computer program 24 retrieves the specified telephone number (or data) from the register 50 and builds a dial sequence order containing the specified telephone number, and transmits the order of dialing sequence over the direct connection 28 to the cell phone 30. The cellular telephone 30 then terminates its connection to the base station system 36, extracts the telephone number from the dial sequence order, and compares the extracted telephone number with those reserved telephone numbers stored in the search table 54. If a correspondence is detected, the cellular telephone 30 immediately recovers the signal CONNECT from the register 56 and transmits it back on the direct connection 28 to the network application computation program 24. The network application computing program 24 is thus induced to believe that an almost instantaneous or remote connection has been achieved and start transmitting its PPP data packets to the cellular phone 30. If the user stores a non-reserved number in the register 50 the network application computation program, the cellular telephone determines that there is no correspondence in any reserved number stored in search table 54 and constructs an asynchronous data call. It is then until the I F of the system emits a CONNECT signal to the network application computer program. Thus, an improved system and method for transmitting PPP data packets over CDMA type devices such as a CDMA type cell phone has been described so far. It should be understood that a person skilled in the art, in reading the description of the invention, could contemplate various modifications of the invention without departing from the spirit and scope of the invention which are intended to be limited only by the appended claims .
