Mobile Communication MMS
Mobile Communication In the MSS environment, network elements communicate via a set of interfaces. Each interface supports a number of operations such as message submission, message retrieval, message forwarding. Each operation is associated with a set of parameters Several interfaces have been standardized in order to ensure inter- operability between devices produced by various manufacturers MMS Interfaces
Mobile Communication There are Eight main interfaces: MM1 MM2 MM3 MM4 MM5 MM6 MM7 MM8 MMS Interfaces
Mobile Communication There are Eight main interfaces: MM1 This is a key interface in the MMS environment. It allows interaction between the MMS user agent, hosted in the Mobile device, and the MMSC. Operations such as message submission, retrieval can be invoked over this interface. MMS Interfaces
Mobile Communication There are Eight main interfaces: MM2 This interface is the interface between the MMS relay and the MMS server. Most commercial solutions offer a combined MMS relay and MMS server in the form of an MMSC. In the case, the interface between the two elements is developed in a proprietary fashion. MMS Interfaces
Mobile Communication There are Eight main interfaces: MM3 This interface is the interface between an MMSC and external servers. Operations over this interface allow the exchange of messages between MMSCs and external servers such as Email servers and SMSCs MMS Interfaces
Mobile Communication There are Eight main interfaces: MM4 This interface is the interface two MMSCs. This interface is necessary for exchanging multimedia messages between distinct MMS environments. MMS Interfaces
Mobile Communication There are Eight main interfaces: MM5 This interface is needed to allow interactions between MMSC and network elements such as HLR. Through the MM5 interface, an MMSC can request information maintained by the HLR. This includes the retrieval of routing information for forwarding a message to another messaging domain or some information about a particular subscriber. MMS Interfaces
Mobile Communication There are Eight main interfaces: MM6 This interface allows interactions between MMSC and user databases. Unfortunately, the MM6 interface has yet to be standardized. MMS Interfaces
Mobile Communication There are Eight main interfaces: MM7 This interface fits between the MMSC and external VAS applications. This interface allows a VAS application to request service from the MMSC and to obtain messages from remote MMS user agent. MMS Interfaces
Mobile Communication There are Eight main interfaces: MM8 This interface is needed to allowing interactions between the MMSC and a billing system, unfortunately, such an interface has not been standardized yet. MMS Interfaces
Mobile Communication WAP specifies an application framework and network protocols for wireless devices such as mobile telephones, pagers, and personal digital assistants (PDAs). WAP is the mobile phone industrys answer to interactive web applications. WAP defines its own set of protocols but models after existing web protocols. WAP
Mobile Communication WAP WAP Architecture WAE Wireless Application Environment: Is a general-purpose application environment where operators and service providers can build applications for a wide variety of wireless platforms. WSP Wireless Session Protocol Provides features also available in HTTP. Additionally, WSP supports long-lived sessions and the possibility to suspend and resume previously established sessions.
Mobile Communication WAP WAP Architecture WTP Wireless Transaction Protocol Is a light-weight transaction- oriented protocol. WTP improves the reliability over underlying datagram services by ensuring the acknowledgement and retransmission of datagram's. WTP is appropriate for mobile browsing WTLS Wireless Transport Layer Security Provides privacy, data integrity and authentication between applications communicating in WAP. Support secure transport service.
Mobile Communication WAP WAP Architecture WDP Wireless Data Protocol Is a general datagram service based on underlying low-level bearers. WDP offers a level of service equivalent to the one offered by the internet User Datagram Protocol At the bearer level, the connection may be a circuit- switched connection or packet switched connection, alternatively the transport of data at the bearer-level may be performed with Short Message Service or Cell Broadcast
