A communications system may include a content provider device having an instant message (IM) content provider contact associated therewith and may be configured to store content. The communications system may include an IM contact server configured to register the content provider device and thereafter allow subscriber access to the IM content provider contact. The communications system may further include a communications server configured to communicate with the content provider device, and a subscriber device configured to access the IM content provider contact from the IM contact server, and download content from the content provider device via the communications server and based upon the IM content provider contact.

Communications system having instant message (IM) contact based communications and related methods

A communications system includes a mobile wireless communications device, a trusted server, and a plurality of host servers. A given one of the host servers is in communication with the mobile wireless communications device. The given host server is configured to generate and send a redirection request to the mobile wireless communications device, the redirection request requesting the mobile wireless communications device to communicate with an other one of the host servers. The mobile wireless communications device is configured to send the redirection request to the trusted server, and the trusted server configured to send the redirection request to the mobile wireless communications device based upon verification of the redirection request.

Communications system including trusted server to verify a redirection request and associated methods

In one embodiment, a network architecture is described for facilitating delivery of data items over a communications network to a mobile communications device. A remote services server disposed in an enterprise network is operable for detecting a data item at a computer system and for processing the data item into processed information that includes address information relating to the mobile communications device. A service gateway disposed in an Internet Protocol (IP) Multimedia Subsystem (IMS) network is operably connected to the remote services server for receiving the processed information using a first protocol, wherein the service gateway includes functionality to transmit the processed information using a second protocol over the IMS network based on routing information obtained from an IMS-aware node.

Architecture for service delivery in a network environment including IMS

In one embodiment, a service gateway decomposition method is described that is operable in an Internet Protocol (IP) Multimedia Subsystem (IMS) environment. A service gateway controller (SGC) is provided for effectuating a signaling interface with respect to at least one remote services server. One or more service gateways (SGWs) are provided for effectuating a message transport interface with respect to the remote services server, wherein the SGC and SGWs are interfaced together using a suitable signaling architecture.

Signaling architecture for decomposed service network elements operable with IMS

A system is provided for providing content to a plurality of mobile electronic devices, where at least some of the mobile electronic devices have wireless communications capabilities. A first network comprises a wireless network system for communicating with at least some of the mobile electronic devices through wireless sessions; a wired to wireless gateway module connected to the wireless network system for interfacing between a wireless portion of the first network and a wired portion of the first network; a session control module interfacing with the wired to wireless gateway module for managing the wireless sessions and wired sessions; and a relay server module interfacing with the session control module and the wired to wireless gateway module, the relay server module for providing relayed content to the mobile electronic devices. A second network comprises an external server for providing content to the mobile electronic devices.

System and method for pushing information from a server to a mobile device

A communications system includes a service provider device, a mobile wireless communications device, and a plurality of communication infrastructure nodes. The plurality of communication infrastructure nodes are configured to generate an association mismatch communications path between the service provider device and the mobile wireless communications device, the association mismatch communications path including at least two communication infrastructure nodes in series. The plurality of communications infrastructure nodes are also configured to generate a corrected association communications path between the service provider device and the mobile wireless communications device from the mismatch communications path, the corrected association communications path including just a single communication infrastructure node from the at least two communication infrastructure nodes.

Communications system configured to correct an association mismatch and related methods

A method and apparatus for virtual private network ('VPN') liveness checking, the method, upon expiration of a timer, sending, over a VPN tunnel, a request to a server located behind a terminator of the VPN; checking whether a response to the request is received within a time interval; if a response to the request is received, resetting the timer; and if a response to the request is not received within the time interval, resending the request if a request count is less than a set number of requests; or providing an inactive tunnel indication to a VPN client manager if the request count equals the set number of requests.

System and method for enabling VPN tunnel status checking

A system is provided for providing content to a plurality of mobile electronic devices, where at least some of the mobile electronic devices have wireless communications capabilities. The system includes a first network for use with a second network. The first network comprises a wireless network system for communicating with at least some of the mobile electronic devices through wireless sessions; a wired to wireless gateway module connected to the wireless network system for interfacing between a wireless portion of the first network and a wired portion of the first network; a session control module interfacing with the wired to wireless gateway module for managing the wireless sessions and wired sessions; and a relay server module interfacing with the session control module and the wired to wireless gateway module, the relay server module for providing relayed content to the mobile electronic devices. The second network comprises an external server for providing content to the mobile electronic devices. The external server communicates directly with either the relay server module or the wired to wireless gateway module.

Systems, methods, and computer-readable media for managing end-to-end security over an IP Multimedia Subsystem (IMS)-enabled network are provided. A first subscriber module accesses an IMS network via an access gateway as a roaming network. The roaming network routes a request for a session from the first subscriber module from its P-CSCF to the I-CSCF of a third-party home network. The third party home network, in turn, routes the request to an S-CSCF implemented at the subscriber's home network, which comprises a second subscriber module. In this way, the session between the two subscriber modules is managed by the subscriber's S-CSCF rather than by a carrier's IMS network, and the subscriber may administer the security relationship without reliance on the carrier or the third party.

Virtual home network arrangement for a subscriber module using IMS

In one embodiment, a scheme is described with respect to a service network system adapted to interoperate in an Internet Protocol (IP) Multimedia Subsystem (IMS) environment wherein signaling and message media planes are decoupled. The service network system comprises a service gateway controller (SGC) that is decomposed from a plurality of a plurality of service gateways (SGWs) operable to effectuate a message transport interface with respect to a remote services server.
