Abstract: The invention proposes a method of controlling a network to which a communication device is connected, comprising the steps of obtaining (S13) connection capability information from the network and evaluating (S14) a connection service based on to the obtained connection capability information. The invention also proposes a correspondingly adapted communication device. Thus, network capabilities related failures may be eliminated since the communication device is aware of the relevant connection capabilities in the network etc.

Abstract: The invention relates to a method for the mapping of packet flows onto bearers in a communication system. The establishment of a session between a terminal and a remote terminal is initiated. Information on the session and packet flows associated with it is received to a second network node. A first network node obtains from the second network node one or two packet classifiers for each of the packet flows. At least a first bearer belonging to the bearers is established between the terminal and the first network node. A packet associated with the first bearer is received in the first network node. The packet is matched with the one or two packet classifiers associated with each of the packet flows to determine a first packet flow among the packet flows. A mapping is established between the first packet flow and the first bearer in the first network node.

Abstract: Multimedia calls addressed an increased data rate are disclosed. The multimedia calls use the multicall supplementary service in circuit switched mobile networks and a multilink operation to separate calls for each portion of the total session. The calling entity establishes several calls to the same party. The sending entity splits the data into the separate simultaneous channels/calls. The receiving entity combines the data received from the separate simultaneous calls (multicall, multilink). IP-based multimedia uses one session for each media component. The IP/CS interworking is arranged, if the CS leg uses a multicall/multilink operation.

Abstract: A method for transport control in a packet switched communication system is disclosed. In the method a data packet assigned with a destination address is received at a node. It may then be detected that the destination address does not meet a filtering criteria. It may then be checked if at least one further destination address has been assigned for the data packet. If it is found that at least one further destination address is assigned for the data packet, the filtering criteria is applied to the at least one further destination address. The data packet is forwarded from the node to a next node in response to detection that the data packet is assigned with a further destination address that meets the filtering criteria.

Abstract: In a mechanism for controlling a communication connection with policy control, after the communication connection with policy control is established in a communication network between a user equipment and service providing network element via a network control element on the basis of an initial packet data protocol context, a modification of the initial packet data protocol context for the communication connection is requested or initiated at the network control element. When the modification is authorized, relevant resources for a modified packet data protocol context usable for signalling traffic and transmission of media stream data are set up.

Abstract: An interworking control mechanism for a communication connection between at least two parties located in different networks provides the following functions: a parameter may be added in a signalling towards one party, which interprets the parameter and shows/indicates a message to the user that a media composition change is not possible and thus prevented even if it would be instructed; otherwise, an announcement is sent from the network to the other party being incapable to execute the media composition change to inform the user about the dropping of a media stream; and a negotiation between the network and the terminal device of the party being incapable to execute the media composition change is initiated in order to modify the remaining session streams, such as to rearrange the available bandwidth and possibly to change a codec to a better one.

Abstract: The present invention relates to a method and system for establishing a connection to a terminal device, wherein a user capability information defining supported types of information streams is set in a compatibility information element within an outband signaling message, and a capability negotiation is performed by transmitting said outband signaling message via an outband control channel. The code or user capability information may be set at the terminal device or at an intermediate network element based on a subscriber profile information obtained from a subscriber database. Thereby, the user capability, such as a multimedia session composition, can be already negotiated or handled during the outband call setup phase, and a corresponding inband negotiation can be avoided.

Abstract: The invention relates to a method and a computer program product for negotiation of a parameter for a protocol that controls data transmission between first Communication Units (CUs) and third CUs via second CUs. An improved protocol parameter adaptation for certain non-transparent data call handovers is achieved by proposing that when an existing association of said first CU with a former second CU is changed to an association of said first CU with a new second CU, protocol entities of the first CU and protocol entities of the third CU associated with the new second CU exchange at least one negotiation message containing a value for said parameter. The invention further relates to a system for data transmission.

Abstract: An apparatus and a method are provided for multiplexing different sessions using the same authorized contexts for media. The method includes distinguishing different control plane sessions by a user equipment, and identifying media flows of a same application among the different control plane sessions by the user equipment by setting a service identifier. The method further includes sending the service identifier by the user equipment to a call state control function including a policy decision function, and authorizing quality of service for a user plane context by the policy decision function. Furthermore, the method includes enabling, by the policy decision function based on the service identifier, the different control plane sessions with media flows of the same application to share the same user plane context with the authorized quality of service to multiplex the different control plane sessions with media flows of the same application.

Abstract: A method and apparatus for establishing a connection, wherein a response to a call setup request of a first type of connection is checked by a signaling control unit and a signaling of a second type of connection received from the other party of the connection is monitored. A third type of connection is set up if the result of the checking step indicates that the setup was not successful. The second type of connection may then be set up when a signal indicating a support of the second type of connection has been detected in the monitoring operation within a predetermined time period. Since a preliminary fallback to the third connection is performed irrespective of the monitoring operation, a more common fallback case can be freed from a monitoring delay.

Abstract: The present invention relates to a method and system for modifying at least one connection parameter of a circuit switched terminal device, wherein the at least one connection parameter can be modified at a called terminal by a corresponding input operation after the receipt of a setup signaling message. The connection parameter is incorporated in an answer signaling message to be transmitted in response to the setup message, and compared with a negotiated connection parameter. Based on the comparison result, a parameter modification is initiated. Thereby, a discreet and fast slip from an offered to a wanted service can be offered at little message traffic.

Abstract: In an implementation of multiple simultaneous calls for a mobile station in a mobile communication system, a common traffic channel is allocated to several simultaneous calls of the mobile station, so that the calls share capacity of the common channel. Logical links are established for each call inside a common radio link protocol or link access control protocol, established over the common traffic channel between the mobile station and an interworking function. The common traffic channel is allocated when the first call or calls are set up, and the capacity of the traffic channel is adjusted dynamically during the calls. The common traffic channel capacity is increased or the allocated capacity is reallocated when a new call is added to the traffic channel. Correspondingly, the capacity is decreased or reallocated when a call is cleared from the common traffic channel.

Abstract: A method and a mobile terminal for communicating with a mobile network element (IWF) comprising communicating with a mobile network element (IWF) using a bearer that is modifiable by a negotiation between the mobile terminal (MS) and the mobile network element (IWF). The data is divided into data units (60) that comprise at least one user data element (61) and at least one status data element (62), said status data element (62) optionally comprising a status indication (63) from the mobile network element (IWF) to the mobile terminal (MS). A need for bearer modification is detected from received status indications (63) in at least two consecutive data units; and a negotiation for bearer modification is initiated, as a response to the detected need for bearer modification.

Abstract: A system can include an application function which is configured to indicate per each multiplexed flow to a rules function that a flow includes multiplexed real time protocol data packets and control packets flow and to indicate the status of each component of the multiplexed flow. The rules function can be configured to inform an enforcement function which is configured to detect the multiplexed flows by the IP addresses and port numbers and to detect the multiplexed subcomponents. The enforcement function can be configured to apply separate gating to data packets and control packets according to the status of each subcomponent.

Abstract: A system and method set specific communication parameters, with the method including identifying a communication relay for allocating addresses. A STUN communication relay can be directed to a specific type of communication such as IMS-specific communication. The communication server ID information is then transmitted to a network, with the communication server being identified as IMS specific. Media flow to and from the communication server for non-specific sessions is therefore blocked. Addresses are allocated by the communication server to user equipment only for specific sessions. Optionally, outbound/uplink traffic may routed from the relay and inbound/downlink traffic may be routed to IMS-specific IP addresses by a policy and charging enforcement function. Also, a time-out unit may re-configure the relay to enable non-IMS sessions if there has been no IMS traffic for a period of time.
