Abstract
Apparatuses, methods, and systems are disclosed for establishing data paths over multiple access network for a multi-access data connection. One apparatus includes a processor and a transceiver that communicates with one or more network functions in a mobile communication network. The processor receives a first session management request via an AMF. Here, the first session management request contains a second session management request sent by a remote unit that communicates with the mobile communication network over a first access network and a second access network, second session management request being sent over the second access network. The processor 405 sends a first request to the access management function to establish a first data path for a multi-access data connection over the first access network and sends a second request to the access management function to establish a second data path for the multi-access data connection over the second access network. Here, both the first data path and the second data path are anchored at a common user plane network function in the mobile communication network.

Claim
1. An apparatus comprising:
a transceiver that communicates with one or more network functions in a mobile communication network; and
a processor that:
receives a first session management request via an access management function, the first session management request containing a second session management request sent by a remote unit that communicates with the mobile communication network over a first access network and a second access network, the second session management request being sent over the second access network;
sends a first request to the access management function to establish a first data path for a multi-access data connection over the first access network, in response to the first session management request; and
sends a second request to the access management function to establish a second data path for the multi-access data connection over the second access network, in response to the first session management request, wherein both the first data path and the second data path are anchored at a common user plane network function in the mobile communication network.
2. The apparatus of claim 1, wherein the first session management request contains an indication to establish a multi-access data connection for the remote unit over both a first access network and a second access network.
3. The apparatus of claim 2, wherein the indication to establish a multi-access data connection for the remote unit over both a first access network and a second access network contains a first session identifier associated with the first access network and a second session identifier associated with the second access network.
4. The apparatus of claim 2, wherein the indication to establish a multi-access data connection for the remote unit over both a first access network and a second access network contains a first session identifier and a multi-access parameter, wherein the first session identifier is associated to both the first access network and the second access network.
5. The apparatus of claim 1, wherein the processor further queries a policy control function for at least one of multi-access routing rules and multi-access quality-of-service (�QoS�) rules associated with the remote unit.
6. The apparatus of claim 5, wherein the processor further sends a session establishment request to the common user plane function anchoring the first and second data paths, the session establishment request including the multi-access routing rules and an indication that the first and second data paths are for a multi-access data connection.
7. The apparatus of claim 1,
wherein the first access network is an access network not defined by 3GPP (�non-3GPP access�) and the second access network is an access network defined by 3GPP (�3GPP access�), and
wherein the second session management request is a Packet Data Unit (�PDU�) session establishment request.
8. The apparatus of claim 7,
wherein sending the first request to the access management function to establish the first data path for the multi-access data connection comprises sending a third session management request without an embedded N1 Session Management container, the third session management request indicating that the access management function is to send it to the first access network, and
wherein sending the second request to the access management function to establish the second data path for the multi-access data connection comprises sending a response to the first session management request, wherein the response contains an embedded N1 Session Management container.
9. The apparatus of claim 8, wherein the N1 Session Management container includes a PDU session establishment access message that contains multi-access routing rules and multi-access quality-of-service (�QoS�) rules associated with the multi-access data connection.
10. The apparatus of claim 1, wherein the second session management request is a request from the remote unit to establish a data connection over a single access network, and the first session management request includes an indication that the remote unit has simultaneous connections to both the first access network and the second access network, wherein the processor further determines to establish a multi-access data connection in response to receiving the first session management request.
11. The apparatus of claim 10, wherein the processor further queries a data management function to determine whether a network subscription of the remote unit allows a multi-access connection in response to receiving the first session management request, and wherein the processor determines to establish a multi-access data connection based on the network subscription of the remote unit.
12. The apparatus of claim 10, wherein the processor further queries a policy control function for at least one of multi-access routing rules and multi-access quality-of-service (�QoS�) rules associated with the requested data connection in response to receiving the first session management request, and wherein the processor determines to establish the multi-access data connection based on the at least one of multi-access routing rules and multi-access QoS rules received from the policy control function.
13. The apparatus of claim 1, wherein the second session management request comprises a mode parameter, the mode parameter containing a requested mode of operation for the multi-access data connection.
14. A method comprising:
receiving a first session management request via an access management function in a mobile communication network, the first session management request containing a second session management request sent by a remote unit that communicates with the mobile communication network over a first access network and a second access network, the second session management request being sent over the second access network;
sending a first request to the access management function to establish a first data path for a multi-access data connection over the first access network, in response to the first session management request; and
sending a second request to the access management function to establish a second data path for the multi-access data connection over the second access network, in response to the first session management request, wherein both the first data path and the second data path are anchored at a common user plane network function in the mobile communication network.
