The Evolved Packet System shall be able to allow for self-managing technologies (e.g. Plug-and-Play) for dynamically adding and removing non-3GPP defined access networks.
Such self-managing technologies shall take into account the Evolved Packet System and access network policies.
E.g. depending on such policies it shall be possible to for the 3GPP system operator to request encryption of user traffic that is transmitted over the access network.
An example could be a WLAN (operated by some WLAN operator) that can, if needed, automatically be connected to a PLMN. This would enable the PLMN operator to provide additional access resources on a dynamic basis and to provide service to more customers (e.g. at mass events).
A family has purchased a family subscription plan that is independent of access (e.g. fixed or wireless) and location (e.g. both when at home and away from home). The subscription contains at least the following components:
Internet access: Operator specific service such as firewall and content filtering (parental control) independent of access for selected devices within the family. The service should be available at home, within the home mobile network and when roaming to a visited mobile network.
Voice/Multimedia: QoS and mobility between home WLAN and LTE wide area
Charging schemas connected to access type, preference and location
Video: Premium Video on Demand Service incl. guaranteed bandwidth and QoS regardless of access network.
Description
Use case 1: Internet access with Parental control and personal firewall
The kids leave their house and take a bus to their grandparents' house.
The operator specific services, like parental control and personal firewall, are invoked for specific users and terminals from both fixed network and from mobile network; this allows the kids to get the same service and filtering inside the home, in the bus going to grandparents and at the grandparents. In this use case the grandparents have a separate service provider than the family but the services will still be provided by the service provider where the family has a subscription.
Use case 2: Voice/Multimedia and Charging
The father travels home after work while talking on the phone with his colleague.
The ongoing Voice/Multimedia call between the father and his colleague is maintained while switching over between LTE Wide area and residential fixed broadband WLAN network. Once the call is switched over to WLAN charging for home-based access is applied. Bandwidth and QoS is maintained for the duration of the call to guarantee the same service delivery.
Use case 3: Video
The kids in the backseat of the car are watching an Internet TV show on their laptop using LTE while driving home from the grandparent's house.
The TV show is sent from an Internet TV provider. Once home the terminal detects indoor WLAN coverage where the subscriber has a WLAN Residential Gateway connected to his Fixed Broadband network. The user or the terminal automatically may select to switch the IP connection to the wireline broadband connection and enable the user to resume watching the same TV show on the same laptop, possibly with a better quality picture as allowed by the available bandwidth, user-specific policy, network policy and QoS setting.
Use case 4: H(e)NB/Femtocell
A subscriber desires to improve coverage and access speed for their 3GPP device in their home. They purchase and install a small eNodeB (Femtocell AP) device for their home which attaches to the home LAN and establishes a connection back to the subscriber's mobile service provider network. The mobile network provider coordinates with the broadband access provider to deliver proper bandwidth and QoS to support a good QoE for calls and data sessions made within the home that access services from the mobile network. The Femtocell also allows some types of data traffic to be shared with the home LAN, including traffic for Internet applications. Local traffic can be discerned and accounted for differently than traffic that is carried on the mobile network.
Use case 5: Application Mobility
A subscriber is in a multimedia call on their mobile device, and then wishes to change the device they are using to a fixed network attached device (e.g. Set Top Box / TV). The multimedia call is handed over from the mobile network to the fixed network after the subscriber chooses to transfer the multimedia call to a STB / TV. Bandwidth and QoS is maintained for the large screen experience to be meaningful. Accounting and settlement is supported among the application and network service providers, and reflects the changes to the access technology and required bandwidth.
Use case 6: Common Quota
A Common Quota (CQ) can be assigned for both fixed and mobile accesses for a limited time period for a defined set of subscriptions. During each session the network elements monitor the CQ which may be consumed by one or more devices over either the wireless or fixed networks.
When a defined percentage of the CQ and/or all the CQ has been consumed, one or more subscribers in the defined set can be notified of the event (e.g. via SMS and/or email).
When the CQ has been consumed the access to the services is blocked.
Use case 7: Video On Demand Service
Video On Demand (VoD) service is provided to the subscriber via the Set Top Box to the TV or to the PC. A user orders a VoD service interacting with the VoD infrastructure, which sends a resource request to the network. The user may also request mid-session requests triggering the increase/decrease of network resources. The requests will be accepted or rejected according to the available network resources.
Use case 8: Broadband Access Wholesale
In Broadband network the wholesale scenario is quite important as it may be required by the regulation, known as unbundling (access, connectivity and services). For example the operator of the broadband access network lease/sell transport of the connection through its own network from the user to the buyer / leased network. So in the wholesale scenario the renting operator has the end-to-end Service responsibility to the customer and is viewed as the "Retailer" of the service or application. While the leasing network operator has the responsibility for the access network and for the connectivity.
