1. A method comprisingreserving, for a particular call, packet network resources of a first packet network according to its own reservation policy;
- andreserving, for the call, packet network resources of a second packet network according to its own reservation policy,the second packet network being coupled to the first packet network and the reservation policy for the first packet network differing from the reservation policy for the second packet network,the reserving packet network resources of the first packet network being based on an indication from a calling party;
the reserving packet network resources of the second packet network being based on an indication from a called party,the first packet network and the second packet network being coupled to each other through a third packet network,the indication from the calling party being a message indicating a limit for packet network resources of the first packet network to be reserved and for packet network resources of the third packet network to be reserved, the indication from the calling party being communicated to the third packet network via a first network edge device, andthe indication from the called party being a message indicating a limit for packet network resources of the second packet network to be reserved and for packet network resources of the third packet network to be reserved, the indication from the called party being communicated to the third packet network via a second network edge device without being communicated via the first network edge device and the indication from the called party being communicated independently of the indication communicated by the calling party.

Abstract
Segmented resource reservation is performed for at least one call. Network resources associated with a first network are reserved according to that network'"'"'s own reservation policy and based on an indication from a calling party. For the at least one call, network resources associated with a second network are reserved according to its own reservation policy and based on an indication from a called party. The second network is coupled to the first network.

5. A method comprising
reserving, for a call, packet network resources of an access packet network according to its own reservation policy; - and
reserving, for the call, packet network resources of a backbone packet network according to its own reservation policy, the backbone packet network being coupled to the access packet network and the reservation policy for the backbone packet network differing from the reservation policy for the access packet network, the reservation policy for the access packet network including a policy that capacity in the access packet network for transmit and receive directions of communication is reserved upon the access packet network receiving a particular message, the reservation policy for the backbone packet network including a policy that capacity in the backbone packet network for transmit and receive directions of communication is reserved at different times, said reserving of backbone packet network resources for the transmit direction being carried out in response to the backbone network receiving a first request to reserve said transmit direction capacity, and said reserving of backbone packet network resources for the receive direction being carried out in response to the backbone network receiving a second request to reserve said receive direction capacity, said first and second requests being received by said backbone network in first and second separate messages received from respective different network entities. - View Dependent Claims (6, 7)
