A system is provided that includes a network entity, such as a packet data switching node (PDSN), and a terminal capable of establishing a data-link connection with the network entity, such as after setting up a physical-layer connection with the network entity. After the data-link connection is established, the network entity and the terminal can configure a network-layer protocol such that data formatted in accordance with the network-layer protocol can thereafter be sent between the terminal and the network entity over the data-link connection. Then, during configuration of the network-layer protocol, the terminal can discover at least one service available to the terminal by receiving, from the network entity, a listing of the at least one available service. The listing of each available service includes an address of a provider of the available service and a port number and / or pathname for accessing the service at the provider.

A method includes receiving, at a network node, a device-to-device D2D discovery request from a first device and sending a D2D discovery response from the network node to the first device. The D2D discovery response includes information associated with a second device that is available to establish a D2D connection with the first device. The network node may perform inquiries regarding D2D connection permission from both devices. If D2D connection is permitted by both devices, the network node may facilitate the D2D scanning by sending each device's scanning information to the other device via a non-D2D link. In parallel to D2D scanning, the network node may speed up D2D link setup by distributing, via non-D2D links, link setup information to each device, where the link setup information may include device credential(s), IP address allocation(s), and / or group owner assignment.

A service discovery protocol may allow clients in a distributed computing environment to search for services. Service providers (or a listener agent) may respond to search requests by publishing or providing corresponding service advertisements or URIs to corresponding service advertisements. When a service provider responds to a discovery search request (either directly or through a listener agent), the provider may choose to publish a protected or an un-protected (complete) advertisement. A protected advertisement may include the set of information necessary to obtain a complete advertisement. Publishing a protected advertisement may force the client to obtain a valid credential from an authentication service before receiving the complete un-protected advertisement from the service provider. A complete un-protected advertisement is needed to create a message endpoint for accessing the service. Forcing clients to obtain a valid credential before receiving an advertisement may provide an additional level of security for the service provider. The security credential that may need to be obtained to receive the complete advertisement may also be used to construct a message gate to communicate with the service where the gate embeds the security credential in each message to the service.

A service discovery protocol may allow clients in a distributed computing environment to search for services using flexible search criteria. A client may send a search message that may be formatted in a data representational language and may include search criteria. The search criteria may specify a service name or a service type or both a service name and a service type. The search criteria may be compared to advertisements for services within the distributed computing environment to find advertisements that match the search criteria. An advertisement may be a document in the data representation language that provides access information for a corresponding service. The client may receive one or more search response messages indicating one or more advertisements that match the search criteria. The client may obtain and advertisement for a located service and may use the advertisement to construct a message gate to communicate with the service according to messages defined by the advertisement.

A system and method of performing device detection and service discovery in a mobile ad hoc communications network, each network node storing a local application directory. One of the network nodes is selected to be a directory server node that stores a combined application directory. The directory server node sends an inquiry message to a listening node when the listening node enters the coverage area of the directory server node. The listening node sends a notification message to the directory server node that includes the local application directory stored in the listening node. The directory server node compares the received local application directory to the combined application directory and updates the combined application directory accordingly. The directory server node sends an update message to each network node by sending an update portion of the combined application directory. Each network node updates the local application directories accordingly.

An ontology-based ad hoc service discovery system includes a local service cache, a cache manager, a service description unit, a query processor, a service semantic inference unit and a node daemon. The local service cache restores a service ontology by collecting class information of all services advertised on an ad hoc network and stores the service ontology. The cache manager manages the local service cache and performs various preset operations on the cache. The service description unit stores a description of a corresponding service for use in initializing the local service cache. The query processor starts performing a semantic based service query protocol by receiving a service query from a user or an application program. The service semantic inference unit inspects whether the service query transmitted from a client is coincident with the content of the service. The node daemon performs a service cache synchronization protocol with neighboring nodes.

The present invention refers to a method for extending replicated service discovery information for determining the availability of requested remote services in a client / server-based network environment (400), wherein each of a multiplicity of client terminals (402) is connected to a single file and / or application server (404, 405) of a specific service provider via a wireless multi-hop network which is based on a store-and-forward messaging principle, i.e. a wireless Personal Area Network (PAN) based on Bluetooth technology. Thereby, said service discovery information is needed for a selection of the optimal service provider. The method comprises the steps of providing (S1) network distance information indicating the number of intermediate network nodes (406) acting as forwarding servers for accessing remotely accessible services between a client terminal (402) and a number of file and / or application servers (404, 405) within said wireless wireless multi-hop network and selecting (S2) a requested remote service running on a file and / or application server (404) of a specific service provider at a network distance in the physical proximity of the respective client terminal (402) which can be reached from said client terminal (402) with a minimum of forwarding delay based on said network distance information. According to one embodiment of the invention, service discovery information is dynamically adapted (S3) to information concerning varying resource availability and / or changing link characteristics within said wireless multi-hop network. In this connection, cached service discovery information is marked as active (S3a) only as long as a file and / or application server (404, 405) participates in a wireless communication session with the respective client terminal (402) and marked as inactive (S3b) after the connection between said server (404, 405) and the respective client terminal (402) is closed and a predefined time-out period has expired, thereby discarding (S3c) outdated service discovery information. According to a further embodiment, information indicating the usage of requested remote services is taken into account during the process of selecting (S2) a specific remote service.

These existing wireless Internet access resources could be mined by users to create spontaneous wireless network providing wide area high-speed data service.

Apparatus and method are provided for distributing service domain reachability information across domain boundaries, thereby allowing domain management systems to determine routing for cross-domain services even when the domains have different technologies or administrators. A Service Domain Manager within each domain advertises to neighbouring domains which services it supports. A domain which receives such advertisements forwards the advertisement on to other domains. Each SDM builds a routing information table which specifies the service, the domain, the next hop, and optionally user defined metrics. The routing information table does not include end-point addresses, in order to keep the size of the table manageable. In this way, the NMS of each domain obtains an end-to-end view of service routes.
