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.

- 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 MC termination point is configured to send, to the service provider, access specific information on behalf of the UE, the first MC path, or both;
- and
- wherein the service provider is configured to send, to the MC termination point, service information associated with the first access network.
6 more elements
2:
- The system of claim 1, 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;
- wherein the MC termination point is further configured to:
- based on not having the access specific information, request access specific information from the fixed core;
- and
- receive requested authentication information from the fixed core.
2 more elements
3:
- The system of claim 2, wherein the access specific information comprises at least one of authentication information or tariff-based information.
4:
- The system of claim 1, 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, wherein based on the MC termination point not having the access specific information, the MC termination point is further configured to:
- request access specific information from the UE;
- and
- receive requested authentication information from the UE.
1 more element
5:
- The system of claim 4, wherein the access specific information comprises at least one of authentication information or tariff-based information.
6:
- The system of claim 1, wherein based on the UE being connected to the MC termination point only through the second MC path, the UE is configured to request service information over the second MC path and the MC termination point from the service provider, the MC termination point is configured to send access specific information to the service provider on behalf of the UE and the service provider is configured to send the requested service information to the UE through the MC termination point and the second MC path.
7:
- The system of claim 6, 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.
8:
- The system of claim 6, 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.
9:
- The system of claim 1, wherein the MC termination point is an Access Traffic Steering, Switching and Splitting User Plane Function (ATSSS UPF).
10:
- 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).
11:
- The system of claim 1, wherein the MC termination point is configured to imitate a characteristic of the first access network.
12:
- The system of claim 1, wherein the MC termination point is configured to maintain a list of services which require access specific information.
13:
- The system of claim 12, wherein the list of services comprises at least one of:
- expected access information, type of information, or a method for exposing authentication information.
14:
- 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.
3 more elements
15:
- The system of claim 14, 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.
16:
- A method for reachability of services specific to a specific access network in a system, the method comprising:
- sending, by a multi-connectivity (MC) termination point of the system to a service provider of the system, access specific information on behalf of a user equipment (UE) of the system, a first MC path, or both, wherein the UE is connectable to the MC termination point through the 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;
- and
- sending, by the service provider to the MC termination point, service information associated with the first access network.
1 more element
17:
- The method of claim 16, 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, access specific information from the UE or the fixed core;
- and
- receiving, by the MC termination point, requested authentication information from the UE or the fixed core;
3 more elements
18:
- The method of claim 17, wherein the access specific information comprises authentication information and/or tariff-based information.
19:
- The method of claim 17, 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 on behalf of the UE.
20:
- The method of claim 17, 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.
21:
- The method of claim 16, wherein the MC termination point is an Access Traffic Steering, Switching and Splitting User Plane Function (ATSSS UPF).
22:
- The method of claim 16, wherein the access specific information comprises at least one of a Mobile Station International Subscriber Directory Number (MSISDN) and or an International Mobile Subscriber Identity (IMSI).
