摘要:
A system, apparatus and method for establishing circuit-switched (CS) communications in packet-switched (PS) multimedia networks such as IMS, and providing services via the PS networks to CS domain users. A dialog is established between terminals through the PS multimedia network. A service is provided to at least one of the terminals by way of the dialog. CS bearer information, including an indication that a communication flow is requested via a CS network, is communicated between the terminals by way of the dialog. A communication flow via the CS network is effected between the terminals as directed by the CS bearer information. IMS or other PS multimedia network services can thus be provided to users otherwise communicating via the CS-domain.

A mechanism for providing a connection from an IP-based network to a circuit-switched network, such as a GSM network is disclosed. A temporary routing number for the circuit-switched network, such as an E.164 number, is delivered to a user terminal, and a circuit-switched call leg is established from the user terminal to the IP-based network using the routing number. Thereby, IMS-services are provided for end users which are located in the radio access network not having sufficient QoS required for voice over IP. In the example of a conference call service, a request for a conference call may forwarded via a data channel or data path to an application server which provides that conference call service. The application server then selects a conference routing number and returns the routing number to the conference host terminal via the data channel. Using the received conference routing number, the conference host terminal can then set up a circuit-switched connection as a call leg of the conference call.

摘要:
The aspects of invention relates to determining a bit rate in a communication device, the communication device including a protocol stack for transferring information to a second communication device, the protocol stack including a protocol layer, the protocol layer providing a logical channel for transferring first information through the protocol layer. According to the method, the first information is transferred through the protocol layer via the logical channel and the bit rate in the logical channel is determined on the basis of second information obtainable from the protocol layer. The invention also relates to a method of determining a bit rate when the communication device is receiving information as well as corresponding transmitting and receiving communication devices.
摘要:
Apparatus, and associated method, for improving packet data communications upon a communication path including a radio-link. Determination is made of the conditions on the radio-link when selecting the optimal size of a transmission window within which to transmit packets of data. And, retransmission time-out values are also selected responsive to the indications of the radio-link conditions.

摘要:
A method provides information on a resource in a communication system. The method includes receiving a request from a first entity in a second entity, the request being addressed to a second resource. The method also includes providing a response to the request comprising a group indication when the second resource defines a group comprising a number of individual resources. Furthermore, user terminals and entities in a communication system are provided configured to implement the method.
