摘要： A telecommunications system includes a mobile network having a plurality of portable communication devices, and a fixed network which includes a signaling agent, a plurality of directory agents, and a plurality of spaced apart attachment points to which the mobile network can attach. In use, each directory agent stores a routing table for routing data to a respective mobile communication device associated with that directory agent. When the point of attachment of the mobile network changes, the mobile network sends a change-of-address message to the signaling agent. In response, the signaling agent is configured to forward the change of address to each directory agent, so that each can update its routing table to take into account the changed point of attachment of the mobile network. Because a signaling agent is provided, each portable device need not itself notify its directory agent when the mobile network moves, and the amount of signaling between the mobile network and the fixed network when the mobile network moves is reduced.

摘要： A method of call control in which a first communications network, detecting calls directed to a destination in the first network; redirects at least some of the calls to a destination in a second network (e.g. on no answer from the destination in the first network). The first communications network obtains from a client on a terminal associated with the destination in the second network a value for the time delay before a call to the destination in the second network is redirected in the second network on no answer to an alternative destination and sets a delay period to a value less than the value of the time delay obtained from the client. When one of the plurality of calls redirected to the second network is not answered in the second network within the delay period, the first communications network redirects the call to an alternative destination associated with the first network.

摘要： A method of routing packets in a packet network is disclosed. The packet network includes a chain of packet nodes, the chain comprising a first and second access node for communicating with one or more mobile nodes and one or more intermediate packet nodes providing a path interconnecting the first and second access nodes. Previous methods are inefficient and lead to additional overhead. The method comprises the steps of: installing, in said intermediate packet nodes, first routing data defining a first routing path in one direction along said chain to a mobile node via said first access node and second routing data defining a second routing path in the opposite direction along said chain to said mobile node via said second access node; operating each of said intermediate packet nodes to: determine, on receipt of a packet destined for said mobile node, whether said packet is from another node on said chain or not; and a) if the packet is determined to be from a node not on said chain, copying the packet and routing said copy along one of said routing paths and routing said packet along the other of said routing paths; and b) if the packet is determined to be from another node on said chain, route said packet along said chain only in the direction in which it is currently travelling.

摘要： The present invention provides a method and system wherein congestion information is taken from a lower level in the protocol stack and used for congestion marking in a higher layer. In particular, the method and system of the invention from a first aspect provide for congestion information in the lower layer to be generated downstream at a congested node, and to be fed back upstream to a source node. The source node then passes the congestion information, or information derived therefrom, up to the corresponding network element responsible for higher layer functions in the protocol stack, where higher level congestion marking can then be performed in dependence on the received lower level congestion information. Thus, congestion information from the lower layer which can typically be generated earlier before significant congestion occurs can be used in higher layer congestion control functions. Preferably the lower layer is the data link layer, and the higher layer is the network layer.

摘要： A method of call control in which a first communications network, detecting calls directed to a destination in the first network; redirects at least some of the calls to a destination in a second network (e.g. on no answer from the destination in the first network). The first network then operates in two phases. In a first phase, for a group of calls redirected to the second network, the time delay before the call is answered in the second network is recorded. When a number of time delays have been recorded, a delay period is set to a value less than the maximum value of the recorded time delays. In a second phase, for a second group of calls redirected to the second network subsequent to the calls of the first group, when a call of the second group is not answered in the second network within the delay period, the call is redirected to a message service associated with the first network.
