  • Patent number: 11949512
    Abstract: A method in a packet-based network like the Internet is provided, which is directed towards packet loss recovery for transmission of a data stream, DS0 in a packet-based network. The method comprises transmitting data packets associated with the data stream, and upon receiving a retransmission request of missing data, retransmitting the missing data applying a selective retransmission of missing data, which may be based on a priority ranking of data types to be retransmitted, performing retransmission if it is determined that missing data will be received in time for display, or performing retransmission with a rate control.

  • Publication number: 20130100863
    Abstract: The present invention concern methods and apparatuses for transporting and using time zone information in an internet protocol multimedia subsystem, IMS, network. When a call session control function, CSCF, node receives a request message related to a user equipment, UE, the CSCF node retrieves and stores time zone information associated with the UE. The time zone information is sent by the CSCF node to at least one other IMS network node, which is then able to support time zone based services and/or charging associated with the UE. The CSCF node may optionally create an Attribute Value Pair, AVP, including the stored time zone information and send a charging message including the AVP to a charging node, to enable usage of the time zone information in charging.

  • Patent number: 8228900
    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.

  • Publication number: 20110295950
    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.

  • Publication number: 20100142372
    Abstract: A method is disclosed for use in a Universal Mobile Telecommunications System network comprising an IP Multimedia Subsystem. The method comprises receiving node status information relating to a first node of the network which indicates an occurrence of an event associated with the first node, determining the existence of a network association established between the first node and a second node of the network that would be adversely affected by the occurrence of the event, and causing the network association to be terminated, thereby allowing a new network association between the first and second nodes to be established in its place.

  • Publication number: 20090175265
    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.

  • Patent number: 7019272
    Abstract: A wall mounted type microwave oven having an external enclosure including a bottom closure wall which includes a suction opening and a top vent opening and an oven cavity which is supported within the external enclosure. The oven cavity has a rearwardly stepped portion to maximize the usable space provided within the oven cavity. An air exhaust air path is formed between the external enclosure and the oven cavity and includes a bottom plenum, a pair of rear air channels and an upper plenum. The rearwardly stepped area divides the space between the oven cavity and the external enclosure into the two rear air channels. At least one blower is provided within the external enclosure for drawing air into the bottom plenum through the suction opening and exhausting the air out through a top exhaust opening which forms part of the top vent opening.
