A method for controlling sessions between an IP Multimedia Subsystem network, IMS network, and at least two communication terminals (202, 204, 206, 208 302, 304, 306), and a communication system connectable to an IP Multimedia Subsystem network, IMS network, and at least two communication terminals (202, 204, 206, 208 302, 304, 306) each associated with a user, the users of the communication terminals sharing a common IP Multimedia Public Identity, IMPU. A control device (210, 310) for controlling sessions between the IMS network and the communication terminals (202, 204, 206, 208 302, 304, 306), and an identity database (212, 312) containing information about the identities of the users and/or the communication terminals (202, 204, 206, 208 302, 304, 306) sharing the common IMPU are provided. Data provision means for providing data, when one of the users/communication terminals (202, 204, 206, 208 302, 304, 306) accepts the session invitation, about which users/communication terminals (202, 204, 206, 208 302, 304, 306) are alerted based on said session invitation are provided. Notification means (222, 322) for sending a notification containing information about the identity of the user/communication terminal (202, 204, 206, 208 302, 304, 306) accepting the session invitation to the other alerted users/communication terminals (202, 204, 206, 208 302, 304, 306) is provided. |
