Data group paging service
First Claim
1. A method for setting up a data connection in a Group Call Service between multiple group members of a voice call group as users of a mobile communication network, the method comprising:
- employing an application server or a service node to establish a data connection controlled by a Session Initiation Protocol (SIP) between a sender and one or more user members of the voice call group;
assigning to each user member of the voice call group a Voice Group Call Service identity (VGCS-ID);
additionally assigning to one or more user members of the voice call group an IMS group identity (IMS Group ID);
upon a said user member activating the VGCS-ID, using the assigned IMS Group ID to check whether the assigned IMS Group ID is available for the activated VGCS-ID;
when said check determines that the assigned IMS Group ID is available for the activated VGCS-ID, registering said user member with the aid of the assigned IMS Group ID; and
routing data from the sender with the aid of the IMS group identity, to an Application Server within an IP Multimedia Subsystem (IMS) which handles a Data Group Call Service between the sender and the user members.

Abstract
A method for setting-up a data connection during a group voice service between several group members as a user of a mobile communication network. In a first method, functions of an IP multimedia subsystem (IMS) are used and a session initiation protocol (SIP) and a controlled data connection between an emitter, a terminal and one or several receivers is produced. Each user is allocated to a group voice service identity (VGCS-ID) an IMS group identity (IMS group ID) and is routed to an application server in the IMS with the aid of the user. A data group voice service is developed between the users. In a second method, each user is routed to the service nodes via GPRS using a group voice service identity (VGCS-ID) and an IP address of a service node, which acts as a relay and a data group voice service is carried out between the users.

11. A system for setting up a data connection in a Group Call Service between multiple group members of a voice call group as users of a mobile communication network, the system comprising:
-
an IP Multimedia Subsystem (IMS); an application server or a service node for establishing a data connection controlled by a Session Initiation Protocol (SIP) between a sender and one or more user members of the voice call group; a user terminal storing an IMS group identity (IMS Group-ID) assigned to a user member of the voice call group and a Voice Group Call Service Identity (VGCS-ID) assigned to each user member of the voice call group; wherein the user terminal can be used to activate the VGCS-ID and to use the assigned IMS Group ID to check whether the assigned IMS Group ID is available for the activated VGCS-ID and, when the assigned IMS Group ID is available for the activated VGCS-ID, to register said user member with the aid of the assigned IMS Group ID; and an Application Server in the IMS to handle a Data Group Call Service between the users, wherein data from the sender is routed with the aid of the assigned IMS Group ID to an Application Server within the IMS which handles a Data Group Call Service between the sender and the user members.

12. A non-transitory computer readable storage medium for use with a computer in a system for setting up a data connection in a Group Call Service between multiple group members of a voice call group as users of a mobile communication network, wherein the computer readable storage medium contains computer executable program instructions for causing the computer to implement the steps of:
-
establishing a data connection controlled by a Session Initiation Protocol (SIP) between a sender and one or more user members of the voice call group; assigning to each user member of the voice call group, a Voice Group Call Service identity (VGCS-ID); additionally assigning to one or more user members of the voice call group an IMS group identity (IMS Group ID); upon a said user member activating the VGCS-ID, using the assigned IMS Group ID to check whether the assigned IMS Group ID is available for the activated VGCS-ID; when said check determines that the assigned IMS Group ID is available for the activated VGCS-ID, registering said user member with the aid of the assigned IMS Group ID; and routing data from the sender with the aid of the IMS group identity, to an Application Server within an IP Multimedia Subsystem (IMS) which handles a Data Group Call Service between the sender and the user members.

13. A method for setting up a data connection in a Group Call Service between multiple group members of a voice call group as users of a mobile communication network, the method comprising:
-
employing an application server or a service node to establish a data connection between a sender and one or more user members of the voice call group; assigning to each user member of a voice call group a routing identifier including a Voice Group Call Service identity (VGCS-ID); additionally assigning to one or more user members of the voice call group an IMS group identity (IMS Group ID); upon a said user member activating the VGCS-ID, using the IMS Group ID assigned to said user member to check whether the assigned IMS Group ID is available for the activated VGCS-ID, and when the assigned IMS Group ID is available for the activated VGCS-ID, registering said user member with the aid of the assigned IMS Group ID; and routing data from the sender with the aid of the routing identifier, to a service node or an application server connected to the mobile communication network which handles a Data Group Call Service between the sender and the user members. - View Dependent Claims (16)

14. A system for setting up a data connection in a Group Call Service between multiple group members of a voice call group as users of a mobile communication network, the system comprising:
-
an application server or a service node for establishing a data connection between users identified as a sender and at least one user member of the voice call group; a user terminal storing a routing identifier including a Voice Group (Call Service Identity (VGCS-ID) assigned to each member of the voice call group and an IMS group identity assigned to a user member of a voice call group; wherein the user terminal can be used to activate the VGCS-ID and to use the assigned IMS Group ID to check whether the assigned IMS Group ID is available for the activated VGCS-ID and, when the assigned IMS Group ID is available for the activated VGCS-ID, to register said user member with the aid of the assigned IMS Group ID; and a Serving GPRS Support Node (SGSN) and a Gateway GPRS Support Node (GGSN) for routing data from the sender, using the routing identifier, to a service node or to an application server connected to the mobile communication network which handles a Data Group Call Service between the sender and the user members.
