    摘要： 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.

    摘要： In order to address the problem of allowing a GGSN of a UMTS core network to work towards multiple Policy Control Functions (PCFs) co-located with P-CSCF nodes using the COPS protocol, a policy control function coordinator (PCF-C) is implemented between the GGSN and the P-CSCF. A single COPS connection is established between the GGSN and the PCF-C while a COPS connection is established between the PCF-C and each of the P-CSCF nodes. Decisions made at the PCFs are routed to the GGSN via the PCF-C, and responses generated at the GGSN are routed to the appropriate PCFs via the GGSN. This architecture avoids conflicts which might otherwise arise with the COPS protocol.

    摘要： In order to address the problem of allowing a GGSN 16 of a UMTS core network to work towards multiple Policy Control Functions (PCFs) 17 co-located with P-CSCF nodes 18 using the COPS protocol, a policy control function coordinator (PCF-C) 15 is implemented between the GGSN 16 and the P-CSCF 18. A single COPS connection is established between the GGSN 16 and the PCF-C 15, whilst a COPS connection is established between the PCF-C 15 and each of the P-CSCF nodes 18. Decisions made at the PCFs 17 are routed to the GGSN 16 via the PCF-C 17, and responses generated at the GGSN 16 are routed to the appropriate PCFs 17 via the GGSN 17. This architecture avoids conflicts which might otherwise arise with the COPS protocol.

    摘要： 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.
