Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation of U.S. application Ser. No. 11/713,703, filed 5 Mar. 2007, the disclosure of which is incorporated herein by reference in its entirety. 
     
    
     FIELD 
       [0002]    The disclosed embodiments relate to a technique for implementing an optional communications service within a communications system involving the participation of a plurality of users. 
       BACKGROUND 
       [0003]    Group calls, instant messaging, interactive gaming and Push-to talk over Cellular (PoC) are examples of optional communications services that may be provided by a communications system, and which involve the participation of a plurality of users of the communications system. Subscriptions by users of the communications system to such optional communications services are conventionally achieved only by separate individual requests from the users through a customer care facility or a self-service portal. The inventors have identified the problem that one user wishing to participate in such an optional communications service with another user depends on such another user already having made its own individual request for subscription to the service, and that this can lead to the service not being used as effectively as possible. 
       SUMMARY 
       [0004]    It is an aim of the presently disclosed embodiments to provide a new technique for implementing an optional multi-user communications service within a communications system that facilitates more effective usage of the optional multi-user communications service.

     DETAILED DESCRIPTION 
       [0023]    The present embodiments are described hereunder, by way of non-limiting example only, with reference to the accompanying drawings. 
         [0024]      FIG. 1  illustrates an example of a communications system  1  in which the disclosed embodiments may be implemented. In  FIG. 1 , a plurality of user terminals  40 ,  60  and  80  (typically, many more than three user terminals would form part of the communications system  10 , but only three are shown for the purpose of explaining the disclosed embodiments) are connected to a communications network  20  via respective wireless interfaces. The communications network  20  may itself comprise a plurality of sub-networks including one or more radio access networks. The network  20  may provide a number of basic services such as standard calls between two user terminals, and may also provide one or more optional communication services such as group calls, instant messaging, interactive gaming and PoC services, which each require a special subscription and which each involve the participation of a plurality of users of the communications system. 
         [0025]    According to at least one embodiment as illustrated in  FIG. 4 , the creation of a subscription to an optional multi-user communications service for a first subscriber/user A of the communications system  10  prompts the creation of subscriptions to the same optional multi-user communications service for one or more other existing subscribers/users of the communications system  10 . 
         [0026]    User/subscriber A is prompted by a message to user terminal  40  asking whether Subscriber A wants those other subscribers/users of the communication system included in his/her personal list (which are also referred to in this specification as “buddies”) to also be provisioned for said optional multi-user communications service. If the answer to this question is yes, the provisioning system makes a query to the list management server that holds and maintains the personal lists for subscriber/user A, retrieves the identities and checks via a subscriber profile database and a terminal inventory database if each such other user/subscriber is already a subscriber to said optional multi-user optional communications system. 
         [0027]    For each of said other subscribers/users for which the result of the check is negative, the provisioning system then creates subscriptions and sends any required device configurations to the respective user terminal devices  60 ,  80 , and sends a notification to the user terminal device  40  for Subscriber A so that Subscriber A knows that he/she can start using said multi-user communications service together with his/her buddies. 
         [0028]    The provisioning system does not need to hold or maintain the personal contact list for subscriber A; it could request the user terminal device  4  associated with subscriber A for details of the identities of the other users/subscribers lists in the personal list for subscriber A. 
         [0029]    An example of a set of communication system elements for implementing the creation of subscriptions for other users/subscribers in the embodiment of  FIG. 4  is illustrated in  FIGS. 2 and 3 .  FIG. 2  illustrates the order of actions/notifications between the system elements, and  FIG. 3  identifies the type of the interfaces between the system elements. 
         [0030]    In  FIGS. 2 and 3 , the following abbreviations are used:
       PM: Profile Manager   TMS: Terminal Management Server   CRM: Customer Relationship Management   SR: Subscriber Repository (such as a Home Location Register (HLR))   IMS: IP Multimedia Subsystem   LMS: List management Server   UCS: Unified Charging Solution   BCAS: Business Communication Application Server   OSS/J: Operating Supporting System java interface   RMI: Remote Method Invocation   WSI: Web Service Interface   SOAP: Simple Object Access Protocol   CORBA: Common Object Request Broker Architecture   OTA: Over The Air technology   XCAP: XML Configuration Access Protocol;   XML: Extended Markup Language       
 
         [0047]    The combination of the PM and TMS is referred to as an Integrated Provisioning Solution (IPS), and it takes care of the notification, subscription and terminal configuration of subscriber A and his/her buddies. The IPS always ensures that it is allowed to create a subscription and set the terminal configuration for each buddy retrieved or obtained from list management server based on the respective subscriber profile and respective device inventory. 
         [0048]    The interaction between the system elements shown in  FIGS. 2 and 3  is described below for the example of a chat service. 
         [0049]    In response to subscriber A subscribing to the chat service, CRM starts the creation of buddy subscriptions for the chat service after obtaining authority from subscriber A to do so (Step  1  in  FIG. 2 ). 
         [0050]    A subscription creation request is routed from the CRM to the PM (Step  2  in  FIG. 2 ). 
         [0051]    According to one variation, a service/access network  100  (a sub-network of network  20 ) associated with subscriber A directly contacts the PM to request the creation of buddy subscriptions (Step  2   a  in  FIG. 2 ). In one example, the CRM gives the IPS advance general authorization to act on any such direct request from the service/access network  100 . In another example, the IPS may automatically make a request to the CRM as to whether there are one or more conditions that need to be met before the buddy subscriptions can be created. Either the service/access network  100  or the IPS can then prompt the subscriber A for specific authorization if any such conditions are set. Alternatively, general authorization is given in advance as part of the basic contract between Subscriber A and the provider/operator of the communications system, and which general authorization is used when Subscriber A subscribes to the chat service, or (in the case of the second embodiment described below) adds one or more additional subscribers/users of the communications system to his/her personal contact list. With this variation, the participation of the CRM and/or subscriber A can be reduced. 
         [0052]    When the PM starts the automated provisioning for the buddies, it first obtains from LMS identities of those other users/subscribers of the communication system included in the personal contact list for subscriber A, i.e. the buddies of subscriber A (Step  3  in  FIG. 2 ). The PM then initiates preparation of the SR, UCS and BCAS by the addition to the databases thereof of any required subscriber information for providing the chat service for the buddies of subscriber A (Step  4  in  FIG. 2 ). 
         [0053]    The PM also ensures that the user terminals for the buddies of subscriber A have the correct settings. The correct terminal settings are sent to the buddies as a configuration message (SMS message) from the Terminal Management Server (TMS) (Step  5  in  FIG. 2 ). The user terminals receive the correct settings (Step  6  in  FIG. 2 ) and send an acceptance message in reply, where the protocol and/or terminals so require. 
         [0054]    Subscriber A is notified by SMS when the buddies are properly provisioned and configured (not shown in  FIG. 2 ). Subscriber A is then able to use the chat service with his or her buddies (Step  7  in  FIG. 2 ). 
         [0055]    According to a second embodiment illustrated in  FIG. 5 , a request by subscriber A for the addition to his/her personal contact list of one or more additional users/subscribers to the communications system prompts the creation of a subscription for such one or more additional users to any optional multi-user communications service for which the subscriber/user A is already a subscriber. With this embodiment, subscriber A also has the possibility to refresh the provisioning of buddies when subscriber A modifies its personal contact list, which personal contact list may be maintained at a list management server (LMS). 
         [0056]    With the above-described embodiments, the probability for user satisfaction and effective usage of the service is increased because there is less risk that the other users in the personal contact list of subscriber A (e.g. friends, family etc.) will not be able to participate in the service because of insufficient subscription data in the network or incorrect device configuration. 
         [0057]    The applicant draws attention to the fact that the presently disclosed embodiments may include any feature or combination of features disclosed herein either implicitly or explicitly or any generalization thereof, without limitation to the scope of any definitions set out above. In view of the foregoing description it will be evident to a person skilled in the art that various modifications may be made within the scope of the disclosed embodiments.
