Abstract:
A system, method, and node for routing a SIP message within an IP Multimedia Subsystem (IMS) from an IMS/SIP client attached to a visited network to a destination address that contains a TEL URI including a local telephone number. The IMS/SIP client places a phone-context within the TEL URI, which specifies whether the local telephone number belongs to the visited network or to the client's home network. The message is delivered to the client's home network, which routes the message according to the phone-context contained within the TEL URI.
Abstract:
A method of facilitating access to IP Multimedia Subsystem, IMS, services by non-IMS enabled terminals. The method comprises registering a non-IMS enabled terminal with a Home IMS gateway, and, in response to said registration, performing an IMS registration on behalf of said terminal between the Home IMS gateway and the IMS using information obtained from an ISIM application present at the Home IMS gateway.
Abstract:
A method and arrangement for providing information to a client from a client access network regarding a requested set of users, at least some of which are connected to other access networks. In response to a client subscription request, the client access network establishes a network subscription with the other access networks. Information updates regarding users in the set are then continuously received and stored in a database of the client access network, whenever the users change their state. In response to a subsequent request for user information from the client, corresponding stored user information is retrieved from the database and sent in a notification to the client.
Abstract:
A method and arrangement for providing information to a client (200) from a client access network (202) regarding a requested set of users (204), at least some of which are connected to other access networks (206). In response to a client subscription request, the client access network establishes a network subscription with the other access networks. Information updates regarding users in the set are then continuously received and stored in a database (214) of the client access network, whenever the users change their state. In response to a subsequent request for user information from the client, corresponding stored user information is retrieved from the database and sent in a notification to the client.
Abstract:
A method of routing a SIP message within an IP Multimedia Subsystem, where the message originates at an IMS/SIP client attached to a visited network and contains as its destination address a TEL URI including a telephone number. The method comprises, at the IMS/SIP client, specifying that the telephone number is a local number of the visited network or of a home network of the client, including at the IMS/SIP client a phone-context within the TEL URI identifying the home network or the visited network according to the specification, and delivering the message from the client to the home network and receiving the message within the home network, and routing the message according to the phone-context contained within the TEL URI.

Abstract:
A filter system for a wall mounted type microwave oven, which has an external enclosure surrounding an oven cavity. The external enclosure includes a bottom closure wall having a suction opening. The external enclosure also includes a top vent opening. An air exhaust path is formed between the external enclosure and the oven cavity wherein air drawn into the suction opening passes through the air exhaust path and is exhausted through the top vent opening. A first filter is provided on the suction side of the air exhaust path and a second filter may be provided on the exhaust side of the air exhaust path. In particular, the first filter may be provided adjacent the suction opening and a second filter may be provided adjacent the top vent opening, such that the first filter is provided at the inlet of the air exhaust path and the second filter is provided at the outlet of the air exhaust path.
