Abstract

A system includes a user equipment (UE), a multi-connectivity (MC) termination point, and a service provider. The UE is connectable to the MC termination point through a first MC path and a second MC path. The first MC path comprises a first access network and the second MC path comprises a second access network. The MC termination point is configured to send, to the service provider, access specific information on behalf of the UE and/or the first MC path. The service provider is configured to send, to the MC termination point, service information associated with the first access network.

First claim

The invention claimed is:

1 . A system, comprising:
a user equipment (UE); a multi-connectivity (MC) termination point; and a service provider; wherein the UE is connectable to the MC termination point through a first MC path and a second MC path, wherein the first MC path comprises a first access network and the second MC path comprises a second access network; wherein the UE is configured to send, to the service provider, via the second MC path and the MC termination point, a request for service information associated with the first access network; wherein the MC termination point is configured to send, to the service provider, the request and access specific information on behalf of the UE, wherein the access specific information comprises authentication information that allows the MC termination point to access the service on behalf of the UE; wherein the service provider is configured to send, to the MC termination point, the service information associated with the first access network; wherein the first access network comprises a radio access network (RAN) and a mobile core, and the second access network comprises a Wi-Fi access point (AP) and a fixed core; and wherein the MC termination point is further configured to:
based on the MC termination point not having the access specific information, request the access specific information from the UE or the fixed core; and
receive the requested access specific information from the UE or the fixed core.

2 . The system of claim 1 , wherein the access specific information further comprises tariff-based information.

3 . The system of claim 1 , wherein the UE requesting the service information associated with the first access network is based on the UE being connected to the MC termination point only through the second MC path;
wherein the MC termination point sending the access specific information to the service provider on behalf of the UE is also based on the UE being connected to the MC termination point only through the second MC path; and wherein the service provider is further configured to, based on the UE being connected to the MC termination point only through the second MC path, send the service information associated with the first access network to the UE via the MC termination point and the second MC path.

4 . The system of claim 3 , wherein the UE or the first access network is configured to inform the service provider that the MC termination point is allowed to request from the service provider service information on behalf of the UE.

5 . The system of claim 3 , wherein the UE or the first access network is configured to instruct the service provider to redirect a response to the UE through the MC termination point.

6 . The system of claim 1 , wherein the MC termination point is an Access Traffic Steering, Switching and Splitting User Plane Function (ATSSS UPF).

7 . The system of claim 1 , wherein the access specific information comprises a Mobile Station International Subscriber Directory Number (MSISDN) and/or an International Mobile Subscriber Identity (IMSI).

8 . The system of claim 1 , wherein the MC termination point is configured to imitate a characteristic of the first access network.

9 . The system of claim 1 , wherein the MC termination point is configured to maintain a list of services which require access specific information.

10 . The system of claim 9 , wherein the list of services comprises at least one of: expected access information, type of information, or a method for exposing authentication information.

11 . The system of claim 1 , wherein:
the UE or the first access network is configured to inform the service provider that the second access network is an eligible access for providing access specific information on behalf of the UE; the service provider is configured to send a message to the UE over the first access network, the message comprising authentication information to be used by the second access network; the UE is configured to send a request message to the service provider, through the second access network, requesting service information, wherein the request message comprises the authentication information received from the service provider; and the service provider is configured to send a message to the UE comprising the requested service information.

12 . The system of claim 11 , wherein the UE or the first access network is configured to instruct the service provider to redirect all future communications through the MC termination point.

13 . A method for reachability of services specific to a specific access network in a system, the method comprising:
sending, by a user equipment (UE) of the system to a service provider of the system via a second multi-connectivity (MC) path and an MC termination point of the system, a request for service information associated with a first access network; sending, by the MC termination point to the service provider, the request and access specific information on behalf of the UE, wherein the UE is connectable to the MC termination point through a first MC path and the second MC path, wherein the first MC path comprises a first access network and the second MC path comprises a second access network, wherein the access specific information is authentication information that allows the MC termination point to access the service on behalf of the UE; and sending, by the service provider to the MC termination point, the service information associated with the first access network; wherein the first access network comprises a radio access network (RAN) and a mobile core, and the second access network comprises a Wi-Fi access point (AP) and a fixed core; and wherein the method further comprises:
based on the MC termination point not having the access specific information, requesting, by the MC termination point, the access specific information from the UE or the fixed core; and
receiving, by the MC termination point, the requested access specific information from the UE or the fixed core.

14 . The method of claim 13 , wherein the access specific information further comprises tariff-based information.

15 . The method of claim 13 , further comprising:
informing, by the UE or the first access network, the service provider that the MC termination point is allowed to request from the service provider service information associated with the first access network on behalf of the UE.

16 . The method of claim 13 , further comprising:
instructing, by the UE or the first access network, the service provider to redirect a response to the UE through the MC termination point.

17 . The method of claim 13 , wherein the MC termination point is an Access Traffic Steering, Switching and Splitting User Plane Function (ATSSS UPF).

18 . The method of claim 13 , wherein the access specific information comprises at least one of: a Mobile Station International Subscriber Directory Number (MSISDN) or an International Mobile Subscriber Identity (IMSI).

19 . The method of claim 13 , further comprising:
imitating, by the MC termination point, a characteristic of the first access network.

20 . The method of claim 13 , further comprising:
maintaining, by the MC termination point, a list of services which require access specific information.

21 . The method of claim 20 , wherein the list of services comprises at least one of: expected access information, type of information, or a method for exposing authentication informati
