Abstract: A roaming gateway has at least one IP network interface, and at least one cellular network interface, and inter-working functions for inter-working between a wireless IP network and a cellular network. The inter-working functions communicate with user devices in an IP network according to a machine-level subscribe-and-notify event package protocol for managing handover of mobile devices roaming between IP and cellular networks. They also poll a cellular network for subscriber status on that cellular network in the absence of a mobility event package. The inter-working functions comprise HSS functionality programmed to access data on a HLR of a cellular network and to perform HSS operations using said data. The gateway applies routing policies specific to call types, allowing or disallowing the anchoring of calls originating in either an IP network or a cellular network based on number prefixes. The inter-working functions comprise an application server programmed to communicate with a user device as a client.

Abstract: A work flow manager (1) of a gateway comprises a process automation component (2), a policy engine (3), and a traffic gateway (4). The work flow manager (1) communicates via the internet (5) over IP with content providers (6) and content aggregators (7). On the other side it communicates over the Internet or over a private IP network, using diverse proprietary and known protocols with service enabler resources (20) including mobile network SMSCs, MMSCs and IMSs (IP Multi-Media Sub-systems). The process automation component (2) presents a GUI to generate a work flow definition in a high level business process execution language (BPEL), with interaction with the service enabler resources (20) which implement the process. The policy engine (3) interprets the BPEL to provide lower-level policy enforcement work, flows in a policy enforcement execution language (PEEL).

Abstract: A virtual mobile node (22) has a pseudo HLR (23) and a pseudo MSC (24). 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.

Abstract: A messaging gateway (1) has a network node layer (20) which interface with mobile devices and manages context for them. A gateway node layer (30) controls access to applications and other functions such as billing. An applications node layer (25) provides requet/response mechanisms for access to applications on external servers. The network node layer (20) has a number of adapters, each associated with a type of mobile device. The gateway node layer (30) 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.

Abstract: A messaging applications router (MAR, 1) has router notes (RNs) which interface with external short message service centers (SMSCs). A management node (MN, 12) 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.

Abstract: 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.

Abstract: 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.
