Abstract

The present invention provides a mechanism for coordinating charging for a multimedia session between a mobile terminal and a remote host on both an application/session level and on an IP/access bearer level. The multimedia session is established over a radio access network via a packet-switched access network coupled to a multimedia system. The multimedia system has one or more multimedia servers for providing multimedia services for multimedia sessions. A token associated with the multimedia session is generated and used to correlate session charges for operations performed in the packet-switched access network and for operations performed in the multimedia system.

Claims

1-52. -52. (canceled)

53. A mobile terminal for use in setting up a multimedia session between the mobile terminal and a remote host using session signaling, where the multimedia session includes plural media data streams, the mobile terminal being configured to communicate with a multimedia system that provides multimedia session services and comprising electronic circuitry configured to perform the following tasks:

initiate the multimedia session using session signaling so that a plurality of media packet access bearers can be established over a packet-switched access network to transport corresponding ones of the media data streams between the mobile terminal and the access point;

receive a service charging identifier; and

determine whether to send the service charging identifier in a packet context message to be sent to the packet-switched access network,

wherein inclusion of the service charging identifier in the packet context message indicates an agreement by the mobile terminal to a charging arrangement that correlates session charges associated with the multimedia session, and wherein absence of the session charging identifier from the packet context message indicates that the mobile terminal does not agree to the charging arrangement.

54. The mobile terminal in claim 53, wherein the session charges include charges for a first operation performed by the packet-switched access network and for a second operation performed by the multimedia system.

55. The mobile terminal claim 54, wherein the electronic circuitry is configured to indicate agreement to a discount charging arrangement for a combined charge for the first and second operation by sending the service charging identifier in the packet context message.

56. The mobile terminal claim 54, wherein the electronic circuitry is configured to indicate agreement to service-based local policy enforcement at an access bearer level orchestrated by a visiting network and enforced by a gate keeper node in the packet-switched access network by sending the service charging identifier in the packet context message.

57. The mobile terminal in claim 54, wherein the packet-switched access network is a GPRS network and the multimedia system is an IP-based multimedia system (IMS) that provides multimedia session services by way of GPRS bearers, and wherein the packet context message is a PDP context activation message.

58. The mobile terminal in claim 57, wherein the service charging identifier is included in a PDP configuration options (PCO) field in the PDP context activation message.

59. The mobile terminal in claim 54, wherein the electronic circuitry is configured to combine the service charging identifier with a media stream identifier.

60-85. -85. (canceled)

86. A method for use in setting up a multimedia session between the mobile terminal and a remote host using session signaling, where the multimedia session includes plural media data streams, the mobile terminal being coupled to a multimedia system that provides multimedia session services, the method implemented in the mobile terminal comprising:

initiating the multimedia session using session signaling so that a plurality of media packet access bearers can be established over a packet-switched access network to transport corresponding ones of the media data streams between the mobile terminal and the access point;

receiving a service charging identifier;

determining whether to send the service charging identifier in a packet context message to be sent to the packet-switched access network,

wherein sending the service charging identifier in the packet context message indicates an agreement by the mobile terminal to a charging arrangement that correlates session charges associated with the multimedia session, and wherein not sending the session charging identifier in the packet context message indicates that the mobile terminal does not agree to the charging arrangement.

87. The method in claim 86, wherein the session charges include charges for a first operation performed by the packet-switched access network and for a second operation performed by the multimedia system.

88. The method claim 87, further comprising:

indicating agreement to a discount charging arrangement for a combined charge for the first and second operation by sending the service charging identifier in the packet context message.

89. The method claim 87, further comprising:

indicating agreement to service-based local policy enforcement at an access bearer level orchestrated by a visiting network and enforced by a gate keeper node in the packet-switched access network by sending the service charging identifier in the packet context message.

90. The method in claim 87, wherein the packet-switched access network is a GPRS network and the multimedia system is an IP-based multimedia system (IMS) that provides multimedia session services by way of GPRS bearers, and wherein the packet context message is a PDP context activation message.

91. The method in claim 90, wherein the service charging identifier is included in a PDP configuration options (PCO) field in the PDP context activation message.

92. The method in claim 87, further comprising:

combining the service charging identifier with a media stream identifier.
