Multi-access data connection in a mobile network
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.
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, wherein the request to establish a data connection comprises a first session identifier and a multi-access parameter, and wherein the first session identifier is associated with both the first access network and the second access network;
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 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 establishment request.
3. 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.
4. 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, wherein the request to establish a data connection comprises a first session identifier and a multi-access parameter, and wherein the first session identifier is associated with both the first access network and the second access network;
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.
5. The method of claim 4 ,
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.
6. The method of claim 4 , 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.
7. 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, 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;
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, wherein the first request includes the first session identifier;
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 the second request includes the first session identifier; and
determines that the request 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, wherein both the first data bearer and the second data bearer are used to carry traffic of the data connection.
8. The apparatus of claim 7 ,
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 establishment request.
9. The apparatus of claim 7 , 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.
10. A method comprising:
communicating with a mobile communication network over both a first access network and a second access network;
transmitting, over the second access network, a request to establish a data connection, 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;
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, wherein the first request includes the first session identifier; 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 the second request includes the first session identifier; and
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, wherein both the first data bearer and the second data bearer are used to carry traffic of the data connection.
11. The method of claim 10 ,
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.
12. The method of claim 10 , 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.
