Definitions
- the present invention relates to communication systems. More particularly, and not by way of limitation, the present invention is directed to a method and terminal for providing Internet Protocol Television (IPTV) and other services to multiple users of an IP Multimedia Subsystem (IMS) network.
- IPTV Internet Protocol Television
- IMS IP Multimedia Subsystem
- IPTV is delivered to the home through a broadband connection from an IPTV service provider to a Set Top Box (STB) connected to a television set.
- STB includes a browser, and all IPTV features are controlled over a browser interface.
- the IPTV delivery process is browser-centric.
- a Session Initiation Protocol (SIP) User Agent in the STB adapts IPTV to IMS requirements.
- SIP Session Initiation Protocol
- a problem with adapting IPTV to IMS is that the browser currently has no concept of individual IMS users. So in the case of a group of users such as a family having a family subscription with different user accounts for the individual family members, the browser must be restarted every time a family member logs into a different user account within the family subscription. The user experience is adversely affected by having to restart the browser when simply switching users.
- the present invention provides a method and terminal for achieving these results.
- the present invention provides simplified provisioning of the STB with IMS user information, quicker response time when switching users in the browser, and closer control of the user experience by the service provider with control of the PIN, aliases, and adding/removing new users in a group.
- a single IMS Private User Identity (IMPI) and password is shared by the whole subscription.
- the present invention is directed to a method of providing
- IPTV Internet Protocol Television
- IMS IP Multimedia Subsystem
- the method includes the steps of associating a group private user identity with a group public user identity and with a plurality of individual public user identities, each associated with a different user in the group; registering a group subscription with the IMS network and an IPTV network utilizing the group private user identity and the group public user identity; and registering a first individual user with the IMS network only when the individual public user identity associated with the first individual user is received, while maintaining the group registration with the IMS network and the IPTV network.
- the method may also include receiving an indication of a change of user from the first individual user to a second individual user; and registering the second individual user with the IMS network in response to the user change, while maintaining the group registration with the IMS network and the IPTV network.
- the present invention is directed to a terminal for providing IPTV and other communication services to a group of users of an IMS network.
- the terminal includes means for associating a group private user identity with a group public user identity and with a plurality of individual public user identities, each associated with a different user in the group; means for registering a group subscription with the IMS network and an IPTV portal utilizing the group private user identity and the group public user identity; and means for registering a first individual user with the IMS network only when the individual public user identity associated with the first individual user is received, while maintaining the group registration with the IMS network and the IPTV network.
- FIG. 1 illustrates the one-to-one relationship between private and public user identities in the IP Multimedia Subsystem (IMS) 3GPP specification;
- IMS IP Multimedia Subsystem
- FIG. 2 is a functional block diagram illustrating the relationships between the IMS subscription, IMS service profiles, and private and public user identities in an embodiment of the present invention
- FIG. 3 is a functional block diagram of a terminal, which includes a browser and local object code in an exemplary embodiment of the present invention
- FIG. 4 illustrates a bootstrapping process by which an STB is provisioned with a
- FIG. 5 is a signaling diagram illustrating the steps of a process in which the Group Subscription User ID is registered with IMS, the local object code learns the address of an IPTV Application Program (IAP), and IPTV is initiated; and
- IAP IPTV Application Program
- FIG. 6 is a signaling diagram illustrating the steps of a process of changing users according to the teachings of the present invention.
- the present invention provides a method and terminal for providing IPTV to multiple IMS users without requiring the browser to be restarted when switching between users. Full IMS functionality is also maintained.
- the browser is initiated on a family or group subscription account and never changes accounts.
- the browser connects to a portal, which keeps track of all the individual accounts under the group subscription and controls the switching between users in the group transparently to the browser. This enables the portal to control the PIN code for the group subscription (typically a simple 4 digit number). Additional benefits are explained below.
- an Application Programming Interface is introduced into the browser based, for example, on javascript properties and methods.
- the API controls the local object code to register different users to IMS.
- the group subscription account is always logged into IMS and to the portal, while individual group members are logged on to IMS only when those individual accounts are invoked.
- FIG. 1 illustrates the one-to-one relationship between private and public user identities in the IP Multimedia Subsystem (IMS) 3GPP specification. Note that the subscription or default user is always associated with the browser. Once the browser is initiated and communication is established with the IPTV Network portal, the methods in Table 1 below may be performed.
- FIG. 2 is a functional block diagram illustrating the relationships between the IMS subscription 11, IMS service profiles 12i-12 5 , and private and public user identities in an embodiment of the present invention. Assuming the browser in the STB totally controls the login process for IMS, it is not necessary to have different IMS credentials for each user in the group. The same IMS credentials, i.e., password and IMS Private User Identity (IMPI) 13 are shared for the whole subscription. A plurality of implicitly registered IMS Public User Identities (IMPUs) 14i-14 ⁇ are associated with the shared IMPI to reach a number of different service profiles.
- IMS credentials i.e., password and IMS Private User Identity (IMPI) 13 are shared for the whole subscription.
- IMPUs IMS Public User Identities
- the group subscription account with the password and shared IMPI 13.
- the individual accounts are dynamically indicated over the browser javascript API. New accounts in the group can be added or removed without having to manually update the STB with the new user information. This would otherwise be a tedious process with the user having to insert long strings of characters using a basic remote control.
- the browser may be implemented in a mobile terminal.
- the portal may be implemented in an IAP IPTV Application platform which is an Application Server (AS).
- AS Application Server
- the Group account (User id 1) is the default account which is connected to the IPTV portal. All communication with the portal takes place over this account.
- the browser indicates for individual services which User ID is invoking the requested service, such as play or playLive.
- Private User IDs (IMPIs) for the individual users in the device are optional. IMPIs may be desirable if other local services are available in the device not controlled from the browser, or if the operator desires stricter security than that provided by the PIN. All users invoked from the browser use the Group Private User ID if no individual IMPIs are defined.
- a benefit of this relationship is that the password is only exchanged at bootstrap and the password is not exposed outside of that bootstrap.
- the User ID and password may be pre-configured in the STB.
- the information may be pre-configured in the STB manually or automatically. If done manually, the User ID and password are inserted manually when the STB connects to the IPTV Network. If done automatically, the STB may automatically connect to an IPTV bootstrap server, which provides an xml file with the User ID and password associated with the STB.
- IPTV bootstrap server which provides an xml file with the User ID and password associated with the STB.
- the Public STB ID is used to register the equipment against the customer account or subscription. The equipment cannot be used by a customer without registration.
- the Private STB ID is used in the automatic configuration of the User ID and password which are delivered during IPTV bootstrapping.
- a User Access Control function controls the logging in of users. The initialization of the browser is associated with a default user, while each feature that is invoked may be associated with a different user.
- the RegisteredUsers data object represents a list of users that are currently registered with IMS. Items in the data object can be accessed using array notation. Table 3 below illustrates the properties of the RegisteredUsers data object.
- the user identifier represents the public user identity
- Tables 4a-4c below illustrate methods of logging users on and off IMS and getting registered users.
- Integer logonUser String userld
- FIG. 3 is a functional block diagram of a terminal 20, which includes a browser 21 and local object code 22 in an exemplary embodiment of the present invention.
- the browser and local object code may be implemented in a STB or an OITF compliant device.
- the browser provides the presentation to the user of the IPTV services.
- a number of exemplary javascript objects are shown: a Video on Demand (VoD) javascript object 23, a Broadcast javascript object 24, a LPVR javascript object 25, and an Other Services javascript object 26.
- the javascript objects may utilize a standardized interface, aligned with the OITF API.
- the javascript objects then communicate with the local object code 22 which then provides all the necessary procedures and signaling with SIP, RTSP and HTTP to realize the services.
- the local object code 22 is shown as being divided into a number of exemplary logical functional modules.
- a User Handling Function module 27 keeps track of the user(s) that are defined in the device. Once defined, any authentication that is required by any interface is retrieved from the User Handling Function module. For IMS deployments, it is necessary to perform registration with IMS prior to providing any IPTV or other IMS service. Multiple users may be registered. Note that only one user is associated with the browser, which is initiated by an IPTV Service Discovery Function module 28.
- the IPTV Service Discovery Function module 28 performs the IPTV service discovery, which is the subscription to IPTV service in IMS.
- the response to the subscription provides the portal address and the URL to fetch the IPTV broadcast channel information.
- the broadcast channel information provides the details necessary to signal the Internet Group Management Protocol (IGMP) requests by an IPTV Media Control Function module 29.
- the portal address is used to start up the browser and load the initial IPTV presentation.
- IGMP Internet Group Management Protocol
- the IPTV Media Control Function module 29 controls ⁇ nicast and multicast streams.
- the session initiation and teardown process is performed with SIP.
- the session setup and teardown process is performed with RTSP.
- the media playback is performed with RTSP, while the broadcast selection and zapping is performed using IGMP.
- An Other IMS Services Function module 31 attempts to capture the services not directly provided by IPTV, such as Presence, Messaging, and Chat services. These services have no direct media interaction except with the browser or local client software implementing the service.
- An optional IPTV Bootstrap Function module 32 facilitates easier deployments of IPTV.
- the device connects to a preconfigured URL with a hardware identifier and an encrypted key, which is used to tie to a subscription. If the subscription is associated to hardware and the key is confirmed, then an xml file is downloaded with details of user accounts and password.
- a Local Player Function module 33 may provide local storage control, provided there is a local hard disk, for broadcasted information both multicast and DVB-T streams.
- a Hybrid System Function module 34 indicates when there may be other types of delivery of TV over terrestrial, satellite, and cable. In order for IPTV services to be integrated with a hybrid system, it is necessary to have access to the channel identifier so the presentation can be customized for those channels.
- FIG. 4 illustrates a bootstrapping process by which an STB is provisioned with a Public Group Subscription User ID, Private User ID, and password.
- the process is performed by the local object code 22, a wireless application protocol proxy referred to herein as a Mobile Internet Enabling Proxy (MIEP) 42, and an IPTV Bootstrap Server, which includes an IPTV Application Program (IAP) 43.
- MIEP Mobile Internet Enabling Proxy
- IAP IPTV Application Program
- the STB is preconfigured with a public STB ID such as a MAC address, a private STB ID, and a default IPTV portal address for initial connection.
- the private STB ID is not visible in the STB. If no private STB ID exists for the STB, one may be given to the user so it can be inserted at startup.
- a subscriber purchases the STB.
- the operator configures the subscriber account with the public STB ID (for example MAC address) to be used for entitlement and the private STB ID.
- the private STB ID is not transmitted over the network, and as noted above, is not visible in the STB.
- the local object code 22 then sends an HTTPS PUT message to the MIEP 42, which sends an HTTP PUT message to the IPTV Bootstrap Server 43.
- the server looks up the subscriber association at step 49 using the public STB ID.
- the server checks the Hash Message Authentication Code (HMAC) and if confirmed, prepares initial information for the STB.
- the initial information may include a Group Subscription User ID 1 authentication information for the Group Subscription User ID, and User IDs for individual users in the group.
- FIG. 5 is a signaling diagram illustrating the steps of a process in which the Group Subscription User ID is registered with IMS (steps 56-58), the local object code learns the address of an IPTV Application Program (IAP) (steps 59-63), and IPTV is initiated (steps 64-68). The process of FIG.
- the User Handling Function module 27 in the local object code 22 sends a REGISTER message 56 to the CSCF 1 which registers the Group Subscription User ID at 57 and returns a 200 (REGISTER) message 58 to the local object code. This registers the Group Subscription User ID with IMS.
- the IPTV Service Discovery Function module 28 in the local object code then sends a SUBSCRIBE message 59 to the CSCF 1 which forwards the SUBSCRIBE message to the IAP 43.
- the IAP returns a 200 (SUBSCRIBE) message 61 to the CSCF 1 which forwards the 200 (SUBSCRIBE) message to the local object code.
- the IAP 43 then sends a NOTIFY message 62 to the CSCF 55 and includes a portal URL for the IPTV Portal (i.e., the IAP 43).
- the CSCF forwards the NOTIFY message to the local object code 22, which returns a 200 (NOTIFY) message 63.
- the local object code has learned the address of the IAP.
- FIG. 6 is a signaling diagram illustrating the steps of a process of changing users according to the teachings of the present invention.
- the signaling goes through the same nodes as FIG. 5, with the addition of an Access Point (AP) 69.
- AP Access Point
- a default user is logged on. Note that the default user (subscription account) is always logged on.
- FIG. 6 and FIG. 2 the process will now be described.
- the STB browser sends a logonUser message 71 to the local object code 22 with the User ID of the new user, for example User 2.
- the User Handling Function module 27 in the local object code then sends a REGISTER message 72 to the CSCF 55 requesting logon (IMS registration) of the new user.
- the CSCF returns a 200 (REGISTER) message 73 to the local object code.
- the STB browser 21 indicates to the local object code 22 that User 2 desires to play Content on Demand (CoD).
- the IPTV Media Control Function module 29 in the local object code sends an INVITE message 75 to the CSCF 55.
- the STB has two active registrations: one for the Group Subscription user, and one for the current active user (User 2). Note that no SUBSCRIBE message is required to begin the session.
- the CSCF establishes the Linear TV/Content on Demand (LTV/CoD) session using the active user IMPU, IMPI, and password.
- the CSCF forwards the INVITE message 75 to the IAP 43 to establish the session.
- the IAP returns a 200 (INVITE) message 77 to the CSCF, which forwards the 200 (INVITE) message to the local object code.
- the STB browser 21 sends a logoffUser message 78 to the local object code 22 indicating that User 2 has logged off.
- the User Handling Function module 27 in the local object code sends another REGISTER message 79 to the CSCF requesting logoff (IMS deregistration) of the old user.
- the CSCF returns a 200 (REGISTER) message to the local object code and the old user is deregistered.
- the new user is then logged on using the process shown in steps 71-73. Note that the browser is not reset. There is a seamless change of users handled by the local object code.
