Abstract
Abstract A method is provided for achieving admission control to a public connectionless packet network. This provides a method of access control which allows service differentiation in a form which permits a user to receive a quality of service guarantee which is better than a “best effort” service. Each transmission by a user across the network includes a message sent to the user from the network. The message includes information about the priority level of the transmission, based on the user's contract with the network provider, and can subsequently be extracted by the network to determine how to handle the transmission, and to determine the resources available for future transmission requests.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
103 words
A method for reserving network resources for a transmission from a first network user, the method comprising: receiving a resource reservation request from the first network user to initiate a reservation; confirming that the required resource is available; sending from the network to the first network user a ticket message containing reserved network resource allocation information, the reserved network resource allocation information being associated with network resources allocated for use by the first network user, allowing access to the network for a transmission from the first network user, only if the transmission includes the ticket message containing the reserved network resource allocation information.
Claim 2
Independent Claim
103 words
A method for reserving network resources for a transmission from a first network user, the method comprising: receiving a resource reservation request from the first network user to initiate a reservation; confirming that the required resource is available; sending from the network to the first network user a ticket message containing reserved network resource allocation information, the reserved network resource allocation information being associated with network resources allocated for use by the first network user, allowing access to the network for a transmission from the first network user, only if the transmission includes the ticket message containing the reserved network resource allocation information.
Claim 3
Dependent Claim
26 words
A method as claimed in claim 1 , wherein the ticket message containing reserved network resource allocation information cannot be altered by the first network user.
Claim 4
Dependent Claim
24 words
A method as claimed in claim 2 , wherein the ticket message containing reserved network resource allocation information is protected by a digital signature.
Claim 5
Dependent Claim
27 words
A method as claimed in claim 1 , where in the ticket message containing reserved network resource allocation information is used to police access to the network.
Claim 6
Dependent Claim
27 words
A method as claimed in claim 1 , wherein the ticket message containing reserved network resource allocation information includes information about a bandwidth allocated to the transmission.
Claim 7
Dependent Claim
28 words
A method as claimed in claim 1 , wherein the ticket message containing reserved network resource allocation information includes information about a priority level allocated to the transmission.
Claim 8
Dependent Claim
31 words
A method as claimed in claim 1 , wherein the ticket message containing reserved network resource allocation information includes information about a quality of service guarantee to the first network user.
Claim 9
Dependent Claim
26 words
A method as claimed in claim 1 , wherein the ticket message containing reserved network resource allocation information includes information about a time of expiry thereof.
Claim 10
Dependent Claim
27 words
A method as claimed in claim 1 , wherein the ticket message containing reserved network resource allocation information includes information about a source address of the transmission.
Claim 11
Dependent Claim
27 words
A method as claimed in claim 1 , wherein the ticket message containing reserved network resource allocation information includes information about a destination address of the transmission.
Claim 12
Dependent Claim
76 words
A node for a communications network, comprising: means for receiving an access request from a user; means for determining whether resources are available for a received access request; means for transmitting to the user a ticket message containing reserved network resource allocation information, if resources are available; and means for restricting access to the network to allow access for transmissions only if the transmissions include an appropriate ticket message containing the reserved network resource allocation information.
Claim 13
Dependent Claim
76 words
A node for a communications network, comprising: means for receiving an access request from a user; means for determining whether resources are available for a received access request; means for transmitting to the user a ticket message containing reserved network resource allocation information, if resources are available; and means for restricting access to the network to allow access for transmissions only if the transmissions include an appropriate ticket message containing the reserved network resource allocation information.
Claim 14
Dependent Claim
47 words
A node for a communications network, as claimed in claim 11 , comprising: means for extracting data from ticket messages containing reserved network resource allocation information associated with respective transmissions; and means for using said data for determining whether resources are available for the received access request.
Claim 15
Independent Claim
63 words
A method of achieving admission control in a network, the method comprising: receiving a resource reservation request from a user to initiate a reservation; sending to the user a ticket message containing reserved network resource allocation information; requiring a subsequent transmission from the user to return the ticket message; and applying admission control on the basis of the content of the ticket message.
Claim 16
Independent Claim
63 words
A method of achieving admission control in a network, the method comprising: receiving a resource reservation request from a user to initiate a reservation; sending to the user a ticket message containing reserved network resource allocation information; requiring a subsequent transmission from the user to return the ticket message; and applying admission control on the basis of the content of the ticket message.
