Abstract: In a telecommunications network, a method of controlling a media gateway to handle a multiplex session, using a media gateway controller, the media gateway and the media gateway controller communicating using a standardised interface protocol, e.g. H.248, providing for a set of command messages each of which contains: a context field for identifying a context of the media gateway; a termination field for identifying one or more terminations of the media gateway; at least one descriptor for defining properties of the context; and optionally a package identity and at least one associated property.

Abstract: A method of negotiating a call capability between signalling points in a telecommunications system. The method comprises sending a capability preference or prioritised list of preferences from an originating signalling point to a terminating signalling point or signalling transfer point, at the Call Control level. A capability acceptance is returned from the terminating signalling point or signalling transfer point to the originating signalling point at the Call Control level, if the terminating signalling point or signalling transfer point accepts a preference sent by the originating signalling point.

Abstract: The present invention relates generally to telecommunication services and, in particular, to a system and method of managing a call, particularly with regard to a modification to bearer characteristics. In one aspect the invention provides a method and system of managing a call in a telecommunication system, the telecommunication system including a network having at least one call controller effecting a call control function and at least one bearer controller effecting a bearer control function, the call controller and the bearer controller separated by a vertical control protocol interface, including providing in at least one message, communicated within the telecommunication system, an indication of the capability of the at least one bearer controller to modify a characteristic of a bearer; and receiving and storing said indication in the at least one call controller.

Abstract: A method of signalling in a telecommunications system that includes a Call Control level and a Bearer Control level, where the Call Control level includes a plurality of Media Gateway Controllers and the Bearer Control level includes a plurality of Media Gateways, each of which is controlled by a Media Gateway Controller. The method includes allocating to each Media Gateway at least one address that corresponds to one of a plurality of different addressing formats, and conveying these addresses between peer Media Gateway Controllers by encapsulating them using a Network Service Access Point addressing format.

Abstract: A method of determining the propagation delay over a packet switched network intented to provide a segment of a telephone circuit. In response to a request for a telephone circuit between two subscribers, a packet containing an echo request message is transmitted over the packet switched network from a first network node to a second network node. The second network node reacts to receipt of the echo request message by transmitting a packet containing an echo reply message to the first network node. The first network node then determines the round trip propagation delay for the packet switched network segment on the basis of the time which elapses between sending the echo request message from the first node and receiving the echo reply message also at the first node.

Abstract: The present invention relates generally to telecommunication services, and in particular, to communicating priority indications between telecommunication nodes in a telecommunication system having a separated call control and bearer control architecture. The present invention provides a number of solutions which map or assign the call level priority to the bearer level.

Abstract: A signalling point of a telecommunications network comprises a Transport Independent Call Control (TICC) part 4. A signalling transport part 6 is arranged to exchange call control signalling information with the TICC part 4 and with a peer TICC part at a remote signalling point. A signalling transport converter 5 is arranged logically between the TICC part 4 and said signalling transport part 6 and is arranged to present a standard interface to the TICC part 4 and a specific interface to the signalling transport part 6, wherein said call control signalling is exchanged between the TICC part 4 and the signalling transport part 6 via the signalling transport converter 5.

Abstract: A method of negotiating a call capability between signalling points in a telecommunications system. The method comprises sending a capability preference or prioritised list of preferences from an originating signalling point to a terminating signalling point or signalling transfer point, at the Call Control level. A capability acceptance is returned from the terminating signalling point or signalling transfer point to the originating signalling point at the Call Control level, if the terminating signalling point or signalling transfer point accepts a preference sent by the originating signalling point.

Abstract: A method of signalling in a telecommunications network comprises generating signalling messages at an Application Part or a User part of an originating signalling point, the messages having a maximum length of 272 octets. The generated signaling messages are transferred to a Message Transfer Part layer 3 (MTP3) of the originating signalling point, and on the basis of the destination signalling point of the received signalling message, it is determined whether or not the message is to be transmitted over an NNI-SAAL signalling link. If the message is to be transmitted over an NNI-SAAL signalling link, the message is transferred to an NNI-SAAL part of the originating signalling point. If the message is not to be transmitted over an NNI-SAAL signalling link, the message is transferred to an MTP2 part of the originating point.

Abstract: Concepts are mapped between Media Gateway Control protocols (e.g., H.248/MEGACO) and specifications for packet-switched services like the General Packet Radio Service (GPRS), enabling Media Gateway Control protocols to be applied in a GPRS environment. For example, a GPRS user-plane entity can represent part or all of a (GPRS) mobility management context by a (Media Gateway Control protocol) Context. Also, a GPRS user-plane entity can represent at least the part of a (GPRS) PDP context going towards a user-plane peer as a (Media Gateway Control protocol) Termination. Two GPRS Tunneling Protocol (GTP) tunnels related to one PDP context (either a primary PDP context or a secondary PDP context) and going towards the same user plane peer can be represented by a (Media Gateway Control protocol) Stream, and a (GPRS) GTP tunnel containing received packets can be represented by a (Media Gateway Control protocol) Local Descriptor.
