Abstract: The invention relates to a method and a communication system comprising at least one first network element connectable to a second network element. At least one of the first and second network elements use one of two or more selectable modes for communicating with another network element. One or both of the network elements, or a third network element, which is connectable with the first and second network elements, performs a mode selection procedure for selecting the same mode for bidirectional communication between the network elements. The modes preferably are different codec types, channel-coding schemes, or radio interface protocol types. The first and/or second network elements may be portable terminal equipments and the third network element preferably is a support node or a means providing a support function such as a CSCF. The mode selection ensures use of one and the same mode, such as a codec, in uplink and downlink directions enabling IP telephony in UMTS using SIP protocol.

Abstract: The invention relates to methods and apparatus for controlling traffic congestion of communication traffic in a communication network. The network includes a first node which is operable to receive communication traffic in the form of data from one of more sending nodes and to pass that data to one or more receiving nodes. The method includes monitoring the possible output data rate of the first node and detecting if the possible output data rate becomes smaller than a maximum data rate value and responsive to that monitoring step performing congestion control whereby the data throughput of a flow of data through the first node is decreased.

Abstract: An emergency telephone call is supported and routed to a Public Safety Answering Point (PSAP) in an IP based packet switched wireless communications network. An activate PDP context request is sent from a user equipment to the network. A parameter in said activate PDP context request indicates that the PDP context will be used to transfer an emergency call. An activate PDP context accept message is returned from said support node to said user equipment. Said activate PDP context accept message acknowledges said activate PDP context request message and provides the address of a call state control function. A call setup request transferred to the call state control function includes the Service Area Identity (SAI). The call state control function selects a PSAP based, at least in part, on the SAI included in the call setup request and forwards the emergency call to the selected PSAP.

Abstract: A method for handling of messages between a terminal and a data network, in which messages of a specific protocol are handled using correspondingly defined specific contexts for messages of the protocol. Messages based on the same specific protocol relate to different service categories. A message is received at the network, and an analysis of the message is performed to determine a service category of the received message. A different specific context is assigned to each received message dependent on the analyzed service category.

Abstract: A method and a communication system which includes a first network element, e.g. portable terminal, connectable to a second network element. One of selectable modes is used for communication. A network element is adapted to perform a mode selection procedure for selecting the same mode for bidirectional communication between the network elements. The mode selection ensures the use of one and the same mode in uplink and downlink direction and thus enables e.g. IP telephony in UMTS using SIP protocol. The invention provides for facilitating a VoIP communication session by way of a radio link with a mobile station. The mobile station forms a QoS (Quality of Service) information element for communication to a radio access network portion. The QoS information element is indicating whether to remove packet header information of the data packets to be communicated upon the radio link pursuant to the communication session.

Abstract: The described invention relates to a communication method and system having at least one communication network to which a plurality of subscribers are attachable and which comprises at least one subscriber information register storing subscriber information including location information related to the subscribers, at least one gateway support node for handling connections to and/or from other networks, and at least one serving node for handling connections with connection originating or terminating elements. At least one network element is provided in addition to the gateway support node which stores information regarding the addresses of serving nodes presently or recently in charge of handling connections to and/or from connection originating or terminating elements. The gateway support node can therefore address this network element for connection, and requires reduced own storage capacity.

Abstract: Within a cellular network, an incoming voice mail message is received at a voice mail server (20), adapted into a format suitable for transmission by a network connection which does not meet a delay requirement for delay sensitive information, dispatched to a mobile station (30), and received, readapted and stored thereat within a storing means (35). Adaptation, transmission, reception and readaptation conform to standards such as the GPRS and the UMTS. The voice mail message is dispatched directly to the mobile station (30) via an IP address of an ISDN address thereof. In this manner, instead of dispatching a message via the SMS, the sending of an adapted voice mail message directly to a mobile station (30) and storing it thereat makes it possible to avoid that a user has to poll a service center by calling in order to have the message delivered.
