Abstract
A session management function (SMF) receives, from an access and mobility management function (AMF), a first request to establish a first session for a wireless device. The first request comprises a cellular internet-of-things (IoT) optimization indication for transfer of data of cellular IoT over a control plane. A second request to establish a second session between the SMF and the UPF is sent to a user plane function (UPF). The data for cellular IoT is received from the UPF via the second session. The data is sent to the AMF via the first session.
Claims20
A method comprising:
- receiving, by a session management function (SMF) from an access and mobility management function (AMF), a first request to establish a first session for a wireless device, the first request comprising a cellular internet-of-things (IoT) optimization indication for transfer of data of cellular IoT over a control plane;
- sending, to a user plane function (UPF), a second request to establish a second session between the SMF and the UPF;
- receiving, from the AMF, the data for cellular IoT via the first session;
- and
- sending, to the UPF, the data via the second session.
A method comprising:
- receiving, by a session management function (SMF) from an access and mobility management function (AMF), a first request to establish a first session for a wireless device, the first request comprising a cellular internet-of-things (IoT) optimization indication for transfer of data of cellular IoT over a control plane;
- sending, to a user plane function (UPF), a second request to establish a second session between the SMF and the UPF;
- receiving, from the UPF, the data for cellular IoT via the second session;
- and
- sending, to the AMF, the data via the first session.
A system comprising:
- an access and mobility management function (AMF);
- and
- a session management function (SMF), comprising:
- one or more communication interfaces;
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the one or more processors to:
- receive, from an access and mobility management function (AMF) via the one or more communication interfaces, a first request to establish a first session for a wireless device, the first request comprising a cellular internet-of-things (IoT) optimization indication for transfer of data of cellular IoT over a control plane;
- send, to a user plane function (UPF) via the one or more communication interfaces, a second request to establish a second session between the SMF and the UPF;
- receive, from the UPF via the one or more communication interfaces, the data for cellular IoT via the second session;
- and
- send, to the AMF via the one or more communication interfaces, the data via the first session.
