  • Patent number: 10454686
    Abstract: A core network node identifies a non-USIM based authentication procedure to be utilized by a wireless communication device, WCD, being served by the core network node. The node obtains a session key associated with the identified non-USIM based authentication procedure. The node converts the session key associated with the identified non-USIM based authentication procedure to i) a first key, K1, for use by the WCD and a base station serving the WCD to derive an encryption or integrity protection key, Kenc/int, for enabling encryption or integrity protection of a communication between the WCD and the base station or ii) a second key, K2, for use by the WCD and the core network node to derive the first key K1. The node then send i) K1 to the base station or ii) K2 to another core network node that is configured to derive K1 from K2.

  • Patent number: 8700784
    Abstract: A method and arrangement for enabling access to a home device in a private network from a remote device located outside the private network. The private network includes a multimedia gateway connected to a multimedia service network. A session invite message is sent from the remote device to the multimedia gateway. In response, connection parameters of a residential gateway in the private network are sent to the remote device, which are associated with the selected home device if a home device identification was included in the received message, or with a proxy function in the multimedia gateway capable of providing home device information, if no such identification was included in the received message. In this way, home devices in the private network can be easily and safely accessed remotely.

  • Patent number: 8543705
    Abstract: A method and arrangement in a multimedia gateway connected to a multimedia service network, for providing access to multimedia services for communication devices connected to a private network. The multimedia gateway may include a device database, a communication unit and a logic unit. A service identity is associated with the multimedia gateway and is valid in the multimedia service network. When a session request is received, a session is established on behalf of at least one device in the private network using said service identity and capabilities of said at least one device. Thereby, no individual service identity is necessary for the selected device(s). If the session request is a session invitation of an incoming request, said at least one device is selected based on capability requirements for the session.

  • Patent number: 8326942
    Abstract: A method of ordering the delivery of a unicast media stream to a second client terminal coupled to an IP Multimedia Subsystem network is described. The method comprises first sending a unicast media order from a first client terminal to an application server of said IP Multimedia Subsystem network. A Session Initiation Protocol INVITE message is then sent from the application server to said second client in response to receipt of said order, the INVITE message containing a media Universal Resource Locator identifying a media source. The Universal Resource Locator is used to exchange Real Time Streaming Protocol signalling between the second client terminal and the application server to initiate and control delivery of the media.

  • Patent number: 8289980
    Abstract: A method and IP Multimedia Subsystem (IMS) gateway for establishing a unicast media session between a media receiver and a media source in an IMS network via a Network Address Translation (NAT) function acting on behalf of the media receiver. A media source controller in the IMS sends a Session Initiation Protocol (SIP) INVITE message to the media receiver to identify the media source. The media receiver obtains NAT bindings for the unicast media session, and the session is established between the media receiver and the media source.

  • Patent number: 8285983
    Abstract: A method of establishing a secure communication channel between a user terminal (2) and a SIP server (14) for the purpose of controlling a service such as an IPTV service. The method comprises sending from the user terminal (2) to the SIP server (14) a session initiation request, via an IP Multimedia Subsystem network, where the IP Multimedia Subsystem network incorporates into the request a P-Asserted-Identity. At the SIP server (14), access to the service is authorized on the basis of said P-Asserted-Identity and, upon successful authorization, a security token is sent to the user terminal (2), via the IP Multimedia Subsystem network. The SIP server (14) and the user terminal (2) use said security token to establish a secure communication channel between each other.

  • Patent number: 8094666
    Abstract: In a network terminals communicate wirelessly through gateway devices with an access node. In the access node an original media access control (MAC) address of a terminal is mapped to a unique, locally administered virtual MAC address for the terminal. This virtual MAC address has a particular portion indicating a unit-specific use including fields that indicate a port index for the gateway device through which the respective terminal communicates with the access node, and an MAC index for the original media access control address of the terminal.

  • Patent number: 8024429
    Abstract: A method and apparatus for establishing a Quality of Service QoS in an access network for a multimedia session between a home network and a remote device located outside the home network. At least one of the remote device and the home network is connected to the access network. When a session invite message is received from the remote device for device discovery in the home network, a default QoS is enforced in the access network. When a session re-invite message is received from the remote device for media communication with a selected home device in the home network, the QoS requirements are determined for the media communication based on session parameters exchanged during the setup of the media communication. An updated QoS is then enforced for the session in the access network based on the determined QoS requirements.

  • Patent number: 7856017
    Abstract: An arrangement and method for relieving the traffic load on an edge node in a broadband Ethernet-based access network, which normally employs traffic separation such that all traffic is routed via the edge node. Peer-to-peer traffic between end users places a large burden on the capacity of the edge node. The edge node identifies peer-to-peer traffic and generates address conversion information for access nodes connected to the end users concerned. The access nodes identify packets forming part of the peer-to-peer connection, modify address information to conceal the address of the source end user from the destination end user, and vice versa, and reroute the packets through the access network to the destination end user without passing through the edge node.
