A virtual mobile node () has a pseudo HLR () and a pseudo MSC (). It transfers an SMS message between an entity in a foreign mobile network having a different technology to an SMS entity connected to the local network. The pseudo HLR and MSC are both located in the home network but operate with the protocol of the foreign network. Thus, communication between the home and foreign networks is via SS7 signalling.

SMS messaging

A messaging gateway () has a network node layer () which interface with mobile devices and manages context for them. A gateway node layer () controls access to applications and other functions such as billing. An applications node layer () provides requet/response mechanisms for access to applications on external servers. The network node layer () has a number of adapters, each associated with a type of mobile device. The gateway node layer () has nodes with access brokers which control access to applications according to user subscriptions, and responses are split up and routed according to adapter capabilities.

Open messaging gateway

A messaging applications router (MAR,) has router notes (RNs) which interface with external short message service centers (SMSCs). A management node (MN,) and each router node maintain a DNS server, and in the routing nodes the DNS servers are linked with a routing agent (RA). Each router node binds to SMSCs transparently to the ESMEs depending upon current load distribution and configuration settings.

Messaging applications router

A short message gateway comprises a gateway function (SMGF) and programs in an HLR or a home network (IMT-2000). It does not have any physical impact on a foreign (PDC) network, and it converts short messages communicated between the home and foreign networks. The gateway function (SMGF) primarily inter-operates with an HLR and an SMSC of the home network, the GMSC providing the link to the foreign network. The gateway allows communication in a wide variety of scenarios for communication with subscribers in the home and foreign networks and roaming subscribers from one to the other.

Short message gateway with interworking for non-compatible networks

An access node has a portal which performs interfacing between a wireless network domain and content/service providers in the Internet. On the wireless side the portal is linked with an SMSC, a CBC, and a USSD server for interfacing with and management of bearer stacks. Service functionality includes modular systems including a Push server, a Pre-paid calling server, and a location server in addition to internal portal functions. The latter provide for subscriber self-provisioning, customer care provisioning, subscriber device provisioning, and service provisioning. Thus, the node caters for both particular subscriber service and mobile device requirements.
