Each domain is defined as a different grouping of subscribers, such as a wireless carrier or subsidiary thereof, a business enterprise, or other defined group of subscribers. The download manager maintains data defining the multiple domains and associations between the domains and wireless services subscribers. Digital content suppliers can publish and manage their products on the server system via a computer network and make their products available to the subscribers for purchase or licensing. The subscribers in each of the domains can access the server remotely to purchase rights to download and use the digital content on associated wireless communication devices.

Techniques for providing remote access to a service provider network include exchanging multiple Dynamic Host Configuration Protocol (DHCP) formatted messages instead of any Point to Point Protocol (PPP) message to provide all PPP functions for accessing a service provider network from a customer node. The service provider network is on provider premises and the customer node is on customer premises different from the provider premises. The DHCP format is used to exchange authentication messages, user profile data on Authentication, Authorization and Accounting (AAA) servers, or session keep-alive echo messages, alone or in some combination. When all are message types are combined, these techniques provide a remote access server (RAS) with the capability to perform all functions presently provided by PPP processes. In some combinations, these techniques allow a modified DHCP server to replace a legacy AAA server.

A system and methods for providing distributed and dynamic network services to remote access users. One of the methods includes providing a first certificate for requesting dynamic network services by a user network entity, and at least one second certificate for requesting static network services by the user network entity. According to one method, a user of the user network entity may generate a first message to request dynamic network services from a network service provider entity. For example, the first message may include the first certificate, a digital signature generated with a private encryption key associated with the first certificate and list of network service that the user wishes to set up dynamically. In one embodiment, when the network service provider entity receives the first message, the network service provider entity verifies the authenticity of the first certificate and, if the first certificate is authentic, the network service provider entity configures a network connection between the user network entity and a data network based on the network services requested by the user in the first message.

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.

Methods, apparatuses and systems directed to the application of network QoS policy to different data types multiplexed over a connection corresponding to a given session between a first host and a second host. In one implementation, the present invention includes a dual gateway architecture where a first gateway terminates the connection with a remote access client, demultiplexes the remote access session data stream into a plurality of separate streams for transmission to a second gateway. The second gateway re-multiplexes the separate data streams into a single remote access session data stream for transmission to a remote access server. The use of separate data streams between the first and second gateways allows for the application of individual policies on the components of the remote access session data flow. For example, a policy scheme can be configured that gives preference to mouse movements, transmitted in a first data stream, over printer traffic, transmitted in a second data stream. The present invention can also be applied to network application protocols, other than remote access protocols, that multiplex more than one “virtual channel” containing different traffic types over a single transport layer connection.
