    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： 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 a method for the control of a connection in a communication network comprising a plurality of nodes (MSC, TSN, MG), a connection (CO) is established stepwise between nodes (MSC, TSN, MG). At least two of the nodes (MSC, TSN, MG) are adapted to insert an entity into the connection (CO), the entity affecting the connection quality, or to remove an entity affecting the connection quality from the connection. An indicator is forwarded between nodes controlling the connection (CO) wherein the indicator indicates whether the connection (CO) comprises an entity affecting the connection quality. A node which decides to insert an entity into the connection or remove an entity adjusts the indicator accordingly before forwarding it to a further node (MSC, TNS, MSC′) controlling the connection (CO). A node (MSC, TSN, MSC′) controlling the connection (CO) checks the value of the indicator when it performs a decision to insert or remove an entity. Nodes and program units for performing the method are also described.
