NowSMS MMSC
NowSMS MMSC是一個功能強大的多媒體訊息服務中心（MMSC），內建到現今的簡訊和彩色簡訊。該NowSMS MMSC是獨一無二的，在於行動設備的測試設施簡化的部署擴展到了行動設備商的網絡供電的多媒體訊息服務。 該NowSMS MMSC能夠支援個人對個人（電話到電話），MMS簡訊，以及應用程式對個人和個人對應用程式MMS簡訊。
NowSMS MMSC支援標準MMS協定藉由開放行動聯盟（OMA）發布，3GPP和3GPP2，包括MMS封裝，MM1，MM3，MM4和MM7協議。支持MMS封裝版本v1.0，v1.1，v1.2和v1.3。除了其他主要MMSC版本使用的幾種非標準MM7變體之外，還支持3GPP MM7版本5.3.0到6.13.0。
超過30家行動運營商正在使用 NowSMS MMSC作為其網絡上多媒體消息服務的主要推動者，並積極利用 MM4協議將其MMSC連接到其他移動運營商網絡。
由於NowSMS提供的靈活性和廣泛的協議支持，許多其他移動運營商使用NowSMS來支持特定的應用和服務。
NowSMS精簡版
允許客戶端透過GSM數據機將SMS消息提交到NowSMS傳送，使用HTTP或SMPP協議。 NowSMS精簡版還提供了範例從Java，PHP和命令行界面提交SMS簡訊。 收到的SMS簡訊可以被路由到使用HTTP，SMPP，或命令行界面的應用程式。
NowSMS精簡版允許客戶透過GSM 數據機使用提交傳遞彩色簡訊，或使用一個支援專有的HTTP介面皆支援HTTP GET和POST操作，或者使用MM7協議。
MM7是一個SOAP/ XML的協議，它透過HTTP POST運作。此外，NowSMS精簡版提供了範例從Java，PHP和命令行界面提交彩色簡訊。 收到的彩色簡訊可以被路由從NowSMS精簡版使用兩種MM7，一是PHP優化HTTP介面，或透過文件/目錄介面的應用程式。
NowSMS Lite allows clients to submit SMS messages to NowSMS for delivery via the GSM modem, using either the HTTP, e-mail or SMPP protocols. NowSMS Lite also provides examples for submitting SMS messages from Java, PHP and a command line interface.
Received SMS messages can be routed to an application program using either HTTP, e-mail, SMPP, or a command-line interface.
NowSMS Lite allows clients to submit MMS messages for delivery via the GSM modem, using either a proprietary HTTP interface that supports both HTTP GET and POST operations, e-mail, or using the MM7 protocol. MM7 is a SOAP/XML based protocol that operates over HTTP POST. Additionally, NowSMS Lite provides examples for submitting MMS messages from Java, PHP and a command line interface.
Received MMS messages can be routed from NowSMS Lite to an application program using either MM7, an HTTP interface optimised for PHP, e-mail, or via a file/directory based interface.
NowWAP Proxy
The NowWAP Gateway（或代理伺服器）是一個功能強大的WAP Gateway進行瀏覽和多媒體訊息。 NowWAP代理是一個WAP Gateway，旨在滿足WAP 2.0和多媒體應用程式，特別是MMS（多媒體信息服務）和 Java下載的需求。 擁有WAP可提供多媒體物件傳送到行動客戶端基本協議的支援，彩色簡訊服務爆炸式成長將有大量需求置換傳統的WAP Gateway。
主要特色
- Bundled 32-bit and 64-bit versions, supporting Windows 2003/2008/2012 Server, or Windows XP/7/8/10 platforms.
- 64-bit version scalable to thousands of transactions per second.
- Supports WAP 2 clients using either Wireless Profiled HTTP/TCP (W-HTTP and W-TCP), or the WSP protocol stack.
- Supports segmentation and re-assembly (SAR) to provide support for larger object delivery to MMS (Multimedia Messaging Service) clients.
- Acts as an HTTP proxy to provide speed enhancements for web browsing via a PC over a GPRS modem or other wireless connection.
- Provides full WAP gateway support for WAP v1.1, v1.2, v1.2.1, v1.3 and v2 WAP clients.
- Interfaces with Radius Accounting for automatic user identification by MSISDN.
- The NowWAP Proxy is available in both standard and secure (WTLS) versions.
- To implement WAP Push and MMS services in conjunction with the NowWAP Proxy, we recommend the use of the Now SMS & MMS Gateway. The Now SMS & MMS Gateway includes a WAP Push Proxy Gateway (PPG) and an Multimedia Messaging Service Centre (MMSC) which compliments the services provided by the NowWAP Proxy.
- Load Balanced and/or Fault Tolerant Configurations are available.
The Now SMS & MMS Gateway requires a connection to an SMSC (Short Messaging Service Centre), or SMS service provider, to interface with SMS and MMS networks. An SMSC connection can consist of one or more of the following:
Android Phone – An active SIM card is required.
GSM Modem – A GSM modem connected to a serial port or USB port. An active SIM card is required.
SMPP (Short Message Peer to Peer Protocol) – A TCP/IP connection over the internet or a private network to a service that supports v3.3 or v3.4 of the SMPP protocol.
UCP/EMI (Universal Computer Protocol / External Machine Interface) – A TCP/IP connection over the internet or a private network to a service that supports v3.5 or higher of the UCP/EMI protocol. UCP/EMI is primarily implemented by CMG SMSCs.
CIMD2 (Computer Interface to Message Distribution, version 2) – A TCP/IP connection over the internet to a service that supports the CIMD2 protocol. CIMD2 is implemented by Nokia SMSCs.
HTTP (Hyper Text Transport Protocol, e.g., the standard protocol for the “web”) – A TCP/IP connection over the internet or private network to a service that accepts SMS messages via an HTTP “GET” based protocol.
This SMSC connection is required to utilise NowSMS. Without an SMSC connection, NowSMS is not able to send or receive messages (although very limited functionality is still available for specialised laboratory environments for phone testing).
