Wireless intelligent network (WIN) support for centralized service control in an IP multimedia subsystem (IMS) network

A method for using a network-based service platform for executing services for a first handset having an existing established communication session with a second handset, comprising:

• determining in the network-based service platform that a feature-event needs to be reported to the first handset;
• sending a message containing feature information from the network-based service platform to the network of the first handset based on a Wireless Intelligent Network (WIN) CallControlDirective (CCDIR) message that is sent from the network-based service platform to a Mobile Switching Center (MSC), wherein the WIN CCDIR message from the network-based service platform to the MSC contains the AnnouncementList and/or DisplayText parameter for instructing the MSC to provide audible and/or visual indications to the first user and/or ActionCode parameter for invoking other processing when the feature-event has been detected;
• invoking the intended feature actions based upon the feature information contained in the message that is received by the network from the network-based service platform;
• and
• responding to the network-based service platform.

A system for using a network-based service platform for executing services on behalf of a first user, wherein the handset of the first user has an existing established communication session with the handset of a second user, comprising:

• means for determining in the handset of the first user that a predetermined feature-event needs to be reported to a network-based service platform;
• means for selecting in the handset of the first user a set of feature information to be sent when the predetermined feature-event has been detected;
• means for sending a message containing the feature information from the handset of the first user to a network, when the feature-event has been detected;
• means for detecting that a trigger condition has been satisfied in the network, when the message containing the feature information is received from the handset of the first user;
• means for determining in the network the identification of a network-based service platform, when the trigger condition has been satisfied;
• means for sending a message containing feature information from the network to the network-based service platform, when the trigger condition has been satisfied;
• means for interpreting the feature information, contained in the message that is received by the network-based service platform, to determine the intended feature actions;
• means for invoking the intended feature actions via service logic execution at the network-based service platform, in conjunction with processing elsewhere in the network;
• means for instructing the network to pass feature information to the handset of the first user, by sending a message from the network-based service platform;
• and
• means for re-establishing a communications session between the handset of the first user and the handset of the second user.
