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, the second session management request being sent over the second access network. The processor 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 first transceiver that communicates with a mobile communication network over a first access network; a second transceiver that communicates with a mobile communication network over a second access network; and a processor that: transmits a request, over the second access network, to establish a data connection; receives a first request to set up a first data bearer for the data connection over the first access network in response to the request; and receives a second request to set up a second data bearer for the data connection over the second access network in response to the request, wherein both the first data bearer and the second data bearer are used to carry traffic of the data connection.
2. The apparatus of claim 1, wherein the request to establish a data connection comprises an indication to establish the data connection over both the first and the second access networks.
3. The apparatus of claim 2, wherein the indication to establish the data connection over both the first and the second access networks comprises 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 the data connection over both the first and the second access networks comprises a first session identifier and a multi-access parameter, wherein the first session identifier is associated with both the first access network and the second access network.
5. The apparatus of claim 1,
wherein the request to establish a data connection contains a first session identifier associated with the second access network and does not contain an indication to establish the data connection over both the first and the second access networks, wherein the first request to set up a first data bearer for the data connection over the first access network and the second request to set up a second data bearer for the data connection over the second access network both include the first session identifier, wherein the processor determines that the request over the second access network to establish a data connection has initiated the establishment of a multi-access data connection over the first access network and the second access network.
6. 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 networdefined by 3GPP (�3GPP access�), and wherein the request to establish a data connection is a Packet Data Unit (�PDU�) session establishment request.
7. The apparatus of claim 1, wherein the request to establish a data connection comprises a mode parameter, the mode parameter containing a requested mode of operation for a multi-access data connection.
8. A method comprising:
communicating with a mobile communication network over both a first access network and a second access network; transmitting a request, over the second access network, to establish a data connection; receiving a first request to set up a first data bearer for the data connection over the first access network in response to the request; and receiving a second request to set up a second data bearer for the data connection over the second access network in response to the request, wherein both the first data bearer and the second data bearer are used to carry traffic of the data connection.
9. The method of claim 8, wherein the request to establish a data connection comprises an indication to establish the data connection over both the first and the second access networks.
10. The method of claim 9, wherein the indication to establish the data connection over both the first and the second access networks comprises a first session identifier associated with the first access network and a second session identifier associated with the second access network.
11. The method of claim 9, wherein the indication to establish the data connection over both the first and the second access networks comprises 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.
12. The method of claim 8,
wherein the request over the second access network to establish a data connection contains a first session identifier associated with the second access network and does not contain an indication to establish the data connection over both the first and the second access networks, wherein the first request to set up a first data bearer for the data connection over the first access network and the second request to set up a second data bearer for the data connection over the second access network both include the first session identifier, the method further comprising determining that the request over the second access network to establish a data connection has initiated the establishment of a multi-access data connection over the first access network and the second access network.
13. The method of claim 8,
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 request to establish a data connection is a Packet Data Unit (�PDU�) session request.
14. The method of claim 8, wherein the request to establish a data connection comprises a mode parameter, the mode parameter containing a requested mode of operation for a multi-access data connection.
