Definitions
- the present invention relates to the exchange of short messages between a central location and a remote location, and more particularly to identifying the recipient of each short message, identifying the data format expected by the recipient of the short message and converting the received short message to the identified data format.
- Short Message Service is an inherent capability of most digital wireless telecommunications systems.
- the radio technologies associated with each of the digital wireless telecommunications system's are technically incompatible at the radio signal layer, but most are compatible at the intersystem SS7 transport layer.
- the differing RF technologies e.g., time division multiple access (TDMA), code division multiple access (CDMA), and global system for mobile telecommunications (GSM)
- TDMA time division multiple access
- CDMA code division multiple access
- GSM global system for mobile telecommunications
- the partial compatibility of these RF technologies is possible because the basic transport format is specified in the IS41 standard; however, many of the messaging details are implementation specific.
- an installed SMSC only supports the protocol of the cellular telecommunication system into which it is installed. For example, if the SMSC is installed into an IS136 type TDMA system, the SMSC supports only the TDMA protocol. Similarly, if the SMSC is installed into a GSM system, then the SMSC supports only the GSM protocol. In other words, although most current SMSC's can interface with any of the currently popular digital cellular systems, the SMSC's do so on an individual basis, not all simultaneously.
- the nodes communicate using different data formatting standards, such as integrated services digital network (ISDN) and the Japanese X.50 standard. Each of the nodes is connected to a format converter.
- the format converter acts as a bi-directional converter for converting between two data formats and thus allows communication between the two nodes.
- the format converter reformats the data formatted in the X.50 standard into the ISDN format.
- the format converter accomplishes the conversion by storing the incoming X.50 data in an aligned data RAM with offsets, to provide an appropriate alignment among the frames of the data.
- a format conversion module reformats the data into the ISDN format one byte at a time.
- a subscriber in an electronic messaging network can access messages in a variety of formats.
- a subscriber may receive messages through a variety of types of equipment, such as a voice mail system, an e-mail system, a facsimile machine and a telephone, all connected to a wireline network.
- the subscriber may access these messages through a pager, a cellular telephone, or a personal digital assistant, each connected to a different wireless network.
- the subscriber selects the wireline or wireless network and media format to be used for delivering messages or notifying a subscriber that a message has been received.
- the subscriber may elect to have notification of a voice mail or facsimile receipt directed to the personal digital assistant (PDA) in the form of an e-mail message.
- PDA personal digital assistant
- the subscriber's selection is implemented through the personal intercommunications inter-networking system, which performs the appropriate data conversion from one protocol to another and delivers the e-mail message.
- an intelligent signaling transfer point is included in a telephone network with a database for storing call processing control information. Calls from one station on the network to another are either passed through or intercepted at the ISTP and screened in accordance with criteria stored in the database, such as time of day, a certain originating area or caller, or a specified call count value.
- a data collection device is provided for use with any one of the following: TDMA; CDMA; frequency division multiple access (FDMA); GSM; and personal access communications systems (PACS) technologies. But, the data collection device does not use multiple such technologies in a single system.
- the present invention meets the needs described above by providing a system and method for interconnecting digital cellular systems of multiple formats so that a customer central location (CCL) can send short messages to, or receive short messages from, multiple remote locations using different digital cellular or PCS standards.
- a short message arbitrator (SMA) intercepts a communication from the CCL to a remote location.
- the SMA retrieves information sent with the communication, such as the mobile identification number (MIN) or other identifying characteristic.
- the SMA uses the identifying characteristic to determine the mobile switching center (MSC) serving the remote location, the wireless access method used in the MSC's market, the CCL's class of service and the type of transport to be used between the SMA and the MSC.
- the SMA determines whether the communication needs to be converted. If the communication needs to be converted, then the SMA converts the communication to the format expected by the remote device and sends the communication over the appropriate transmission path.
- the SMA also intercepts a communication from a remote location to the CCL.
- the SMA retrieves information sent with the communication, such as the MIN and " MSC identifier, or other identifying characteristic.
- the SMA uses the identifying characteristic to determine the recipient of the communication, in this case the CCL, and the class of service expected by the recipient.
- the SMA also uses the information stored in the database to determine whether the communication should be converted. If the communication should be converted, then the SMA performs the conversion and sends the communication to the CCL.
- wireless e.g., digital cellular and PCS

- the present invention is directed to a system and method for interconnecting digital cellular systems of multiple formats so that a customer central location (CCL) can send short messages to, or receive short messages from, multiple remote locations using different digital cellular or PCS standards.
- a short message arbitrator intercepts a communication between the CCL and the remote locations.
- the SMA retrieves information sent with the communication, such as the mobile identification number (MIN) or other identifying characteristic.
- MIN mobile identification number
- the information is used to search a database to determine the data format used by the sender and expected by the recipient. Based upon the information retrieved from the database, the SMA determines whether the communication should be converted. If the communication should be converted, then the SMA converts the communication and transmits the communication to the intended recipient over the appropriate transmission path.

- FIG. 1 shows an exemplary system for providing a flexible bi-directional data transport between a CCL 100 and one or more remote locations using wireless technologies.
- the CCL 100 sends and receives data to and from remote locations 123, 124, 125 and 126.
- Data from the CCL 100 is transferred to the SMA 104 using a public voice/data transport 102 over data circuits 101 and 103.
- the SMA 104 converts the CCL's data to the proper format for transport to MSC's 109, 110, 117 and 119.
- the SMA 104 utilizes two routes for delivering the CCL's data to MSC's 109, 110, 117, and 119.
- the SMA 104 routes the CCL's data to one of the MSC's 109, 110, 117, and 119 by: 1) using a data circuit 105 to an SS7/IS41 Network 106, then over a data circuit (107, 108, 115 or 116) to the MSC (109, 110, 117, or 119) that is intended to receive the transmitted data; or 2) using a data circuit 103 back to the public voice/data transport 102, then over a data circuit (111 , 112, 118, or 120) to the MSC (109, 110, 117, or 119) that is intended to receive the transmitted data.
- the CCL's data is routed to the selected wireless market.
- AMPS advanced mobile phone service
- TDMA time division multiple access
- CDMA code division multiple access
- GSM global system for mobile telecommunications
- the CCL 100 provides for the bi-directional transport of data between a CCL 100 and its remote locations (123, 124, 125, or 126) using a wireless link (Cellular or PCS).
- the CCL 100 can use one or more methods to deliver data to the SMA 104.
- the various methods employ a variety of communication system components. Below are four examples:
- the SMA uses an identifying characteristic, such as the mobile identification number (MIN) or international mobile station identifier (IMSI), that was received with the data, to retrieve the CCL's profile 130 from a SMA database 128.
- the SMA determines the following from the CCL profile: 1) the MSC (109, 110, 117, or 119) serving the remote radio (113, 114, 121 or 122); 2) the wireless access method used in the MSC's market; 3) the CCL's class of service; and 4) the type of transport to use between the SMA 104 and the selected MSC (109, 110, 117, or 119).
- the SMA determines whether any alterations are required to the data or identifying characteristic to make the data compatible with a technologically dissimilar receiving unit or system.
- the CCL's class of service may include one of the following: "CELLEMETRY” data service; short message system (SMS); asynchronous digital data; or data over circuit switched voice cellular.
- "CELLEMETRY” data service is available to AMPS (analog and digital) radios
- SMS and asynchronous digital data are available to digital radios (CDMA, GSM and TDMA)
- circuit switched voice cellular is available in all methods of wireless access.
- other classes - of service may be used with the CCL 100 of the present invention. For simplicity only one CCL 100 is illustrated in FIG. 1. However, the SMA can support multiple CCL's. Each CCL served by the SMA has a CCL identifier that is stored in the database.
- the controller 201 manages communication over the data circuits 103 and 105.
- the SMA database 128 (FIG. 1) stores a profile for each CCL 100 supported by the SMA 104.
- the profile provides information to support the conversion and transport of data between a central location, such as CCL 100, and its remote locations, such as remote locations 123, 124, 125, and 126. From the stored profiles the SMA determines the recipient of the communication, as well as the method of data transport and any data conversions that are necessary.
- the SMA analyzes the information about the CCL and the remote device stored in the database to determine whether the CCL and the remote are using compatible or incompatible data formats. If the CCL and the remote are using incompatible data formats, then the SMA converts the data. As will be apparent to one skilled in the art, the conversion from one data format into another can be managed in any suitable way, e.g., through multiple bi-directional translators 205.
- FIG. 3 and FIG. 4 are flow diagrams illustrating exemplary communication methods of the present invention. These figures illustrate the communication methods utilized to transfer data between the customer central location (CCL) 100 and the • remote locations (123, 124, 125, and 126) of FIG. 1.
- the communication methods of FIG. 3 and FIG. 4 allow the remote locations (123, 124, 125, and 126) and CCL 100 to communicate, even though they are connected by multiple wireless (e.g. digital cellular and PCS) systems using multiple, otherwise incompatible protocols or data formats.

- Communications method 300 begins at step 302 and proceeds to step 304.
- the CCL 100 transports the data to SMA 104.
- the SMA 104 at step 306 receives the data and retrieves the MIN, or other identifying characteristic, transported with the data.
- the SMA 104 uses the MIN to retrieve the CCL's profile 130 from " the SMA database 128.
- the SMA 104 determines the MSC (109, 110, 117, or 119) that is serving the remote radio (113, 114, 121 or 122) identified by the MIN, the wireless access method or data format used in the MSC's market, the class of service or data format used by the CCL, and the method of transport to use between the SMA 104 and the selected MSC (109, 110, 117, or 119), in step 310.
- the SMA determines whether the data formats used by the CCL and the remote are compatible. If the data formats are compatible, then the Yes branch is followed to step 313. However, if the data formats are not compatible, then the No branch is followed to step 312. At step 312, the SMA 104 converts the data to the proper format.
- the SMA transports the data to the • appropriate MSC (109, 110, 117, or 119) using the method of transport specified in the database.
- the MSC receives and transports the data to the radio (113, 114, 121, or 122) associated with the remote location (123, 124, 125, or 126).
- Communications method 300 then proceeds to step 316.
- the radio receives the converted data and transports it to the remote location (123, 124, 125, or 126).
- communications method 300 proceeds to step 318 and the method ends.
- FIG 4 is a flow diagram illustrating an exemplary remote communications method 400 used by the remote locations (123, 124, 125, or 126) to transfer data to the CCL 100.
- the remote communications method 400 illustrates the steps used by a remote location (123, 124, 125, or 126) to transport data to the CCL 100.
- Remote communications method 400 begins at step 402 and proceeds to step 404.
- the remote location (123, 124, 125, or 126) commands its radio (113, 114, 121, or 122) to send data to its associated MSC (109, 110, 117, or 119).
- the MSC (109, 110, 117, or 119) receives the data and transports it to the SMA 104.
- the remote communications method 400 then proceeds to step 408.
- the SMA 104 receives the data and retrieves the identifying characteristics, such as the MIN (or IMSI) and MSC identifier (MSCID), from the data.
- the SMA 104 searches the SMA database 128 using the MIN and MSCID that the MSC (109, 110, 117 or 119) transported with the data.
- the SMA 104 determines from the SMA database 128: 1) the CCL identifier; 2) the class of service used by the identified • CCL 100; and 3) the wireless access method used by the MSC.
- the SMA compares the class of service used by the CCL and the wireless access method used by the MSC to determine whether the data formats are compatible in step 411. If the data formats are compatible, then the Yes branch is followed to step 413. However, if the data formats are incompatible, then the No branch is followed to step 412 and the data is converted. Once the data is converted, the method proceeds to step 413. In step 413, the SMA delivers the data to the CCL. The SMA delivers the data to the CCL using a transmission path that is appropriate for the CCL identified by the CCL identifier. Then, remote communications method 400 proceeds to step 414 and ends.

Abstract
L'invention concerne une position centrale client (CCL) communiquant avec plusieurs dispositifs sans fil distants utilisant des formats de données ou des protocoles de services de messages courts (SMS) réciproquement incompatibles. Une communication d'une position CCL à un dispositif distant ou d'un dispositif distant à la position CCL passe par un arbitre de messages courts (SMA), lequel détermine les caractéristiques d'identification du dispositif recevant la communication. A partir de ces caractéristiques, l'arbitre de messages courts détermine le format de données prévu ainsi que la voie de transmission menant au dispositif. L'arbitre SMA confère alors à cette communication le format de données prévu, puis transmet ladite communication sur la voie de transmission appropriée.
