©LAWanninger 2001 Intercarrier SMS Routing One basic difficulty in developing SMS based services is the variety of protocols used in SMS Centers (SMSC). The European Telecommunication Standards Institute (ETSI) has approved four SMSC protocols, each of which has a slightly different functionality and quite different character conversions: SMPP (by Logica) CIMD (by Nokia) UCP/EMI (by CMG) SMS2000 (by SEMA) Another difficulty is that most U.S. carriers use protocols other than GSM (CMDA, TMDA, Analog, iDen) Not all U.S. carriers have SMSCs and/or do not offer direct high speed connections

©LAWanninger 2001 SMS Message Routing - Present At present, any SMS message sent between two cell phones within the same carrier network is merely routed through the carrier’s network in the carrier’s SMS format (i.e., SMPP). In contrast, when an SMS message is sent to a cell phone in a different carrier network, the message is presently switched to SMTP (Simple Mail Transfer Protocol) and routed through the Internet to the other carrier who in turn switches the message from SMTP to their SMS format and routes the SMS message to the target phone. SMTP is a protocol for sending messages between servers. Most systems that send mail over the Internet use SMTP to send messages from one server to another. SMTP is also generally used to send messages from a mail client to a mail server.

©LAWanninger 2001 Current U.S. Inter-Carrier SMS Routing Method The previous figure is a scenario in which Cellular Operator “A” uses SMPP for SMS messaging and Cellular Operator “B” uses CIMD for SMS messaging. SMTP is a protocol for sending messages between servers. Most systems that send mail over the Internet use SMTP to send messages from one server to another. SMTP is also generally used to send messages from a mail client to a mail server.

©LAWanninger 2001 Implications of 2.5G and 3G for U.S. Intercarrier message routing In the case where a carrier’s 2G network and 2.5G network reside on the same physical network (i.e., a card swap is all that is required to upgrade the network), the SMS routing is largely unaffected. In the case; however, where a carrier’s 2G network and 2.5G network reside on different physical networks, the carrier must have an internal routing capability to switch SMS messages between the 2G and 2.5G networks. In this latter scenario, all messages remain in the single SMS format used by the carrier. The same scenarios will apply when upgrading from 2.5G to 3G.

SMS message with requested content arrives on callers mobile 2. Web-SMS sends a command to REX, which is client to Web-SMS, to fetch content in real time from the MIP 3. Content fetched from the MIP through an HTTP connection in HTML format. REX converts the content into an SMS message 4. Content delivered to the SMSC SMS IVR

©LAWanninger 2001 AS EUROPE ZOOMS AHEAD, U.S. FIDDLES WITH FORMATS (New York Times 07/27/99) Wireless service providers in Europe are pulling ahead of U.S. carriers in developing wireless data services. European carriers plan to take advantage of faster Web transmission technology and general packet radio service (GPRS) to deliver the services. GPRS, which will be available next year, will support transmission speeds fast enough to browse the Internet in full color. Users will also be able to use GPRS to stay connected to the Internet for an entire day. In offering GPRS, carriers will be able to charge subscribers based on the amount of data transmitted, rather than by the minute. While industry players in the U.S. are also pursuing wireless data, the market has been stymied by a lack of standards and carriers' differing opinions over which 3G technology should be adopted. Europe's adoption of a single standard has helped carriers offer built-in paging and messaging functions years before such features were launched in the U.S.

©LAWanninger 2001 Trends in Wireless Technologies and Services Vendors will make big promises to promote early adoption. Corporate use will shape demand for wireless data. Mobile IP adoption will vary across geographies. Users will opt for “always-on” or international roaming. 3G wireless technologies will converge around two standards.

©LAWanninger 2001 Giga Recommendations Don’t expect 3G data rates before Opt for short-term contracts and centralized procurement. Plan to support at least two types of wireless devices.
