Abstract
A method and apparatus for implementation of split charging in an Internet protocol multimedia subsystem, allowing subsystem users to negotiate at setup and at a modification of a session initiation protocol session which user will be charged for each multimedia component of the subsystem. A method includes transmitting a first message to a user equipment for initiating a call, the first message including a split charging offer request and a first split charging offer ratio, and receiving a second message from the user equipment, the second message comprising a second split charging offer ratio. The method also includes processing the second message for determining whether a user of the user equipment accepted the call, whether the user of the user equipment accepted the split charging offer request or the user offered an increase or decrease in the first split charging offer ratio, and whether a network element of an Internet protocol multimedia subsystem accepted, approved, and agreed upon the second split charging off ratio for allowing a group of users to negotiate which user will be charged for each component of the Internet protocol multimedia subsystem.
