Abstract
A target access and mobility management function (AMF) receives, from a source AMF, a first message for a handover of a wireless device. A second message requesting creation of at least one first session for the wireless device is sent to a target session management function (SMF). A third message confirming creation of the at least one first session is received from the target SMF. Based on the third message, a fourth message causing release of at least one second session for the wireless device is sent to the source AMF.
Claims16
A method comprising:
- receiving, by a target access and mobility management function (AMF) from a source AMF, a first message for a handover of a wireless device;
- sending by the target AMF, to a target session management function (SMF), a second message requesting creation of at least one first PDU session between a first user plane function and the wireless device;
- receiving by the target AMF, from the target SMF, a third message confirming creation of the at least one first PDU session between the first user plane function and the wireless device;
- and sending by the target AMF, to the source AMF and in response to receiving the third message confirming the creation of the at least one first PDU session, a fourth message causing release of at least one second PDU session between a second user plane function and the wireless device.
A target access and mobility management function (AMF) comprising:
- one of more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the target AMF to:
- receive, from a source AMF, a first message for a handover of a wireless device;
- send, to a target session management function (SMF), a second message requesting creation of at least one first PDU session between a first user plane function and the wireless device;
- receive, from the target SMF, a third message confirming creation of the at least one first PDU session between the first user plane function and the wireless device;
- and
- send, to the source AMF and in response to receiving the third message confirming the creation of the at least one first PDU session, a fourth message causing release of at least one second PDU session between a second user plane function and the wireless device.
A system comprising:
- a source AMF;
- a target session management function (SMF);
- and
- a target access and mobility management function (AMF) comprising:
- one of more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the target AMF to:
- receive, from the source AMF, a first message for a handover of a wireless device;
- send, to the target session management function (SMF), a second message requesting creation of at least one first PDU session between a first user plane function and the wireless device;
- receive, from the target SMF, a third message confirming creation of the at least one first PDU session between the first user plane function and the wireless device;
- and
- send, to the source AMF and in response to receiving the third message confirming the creation of the at least one first PDU session, a fourth message causing release of at least one second PDU session between a second user plane function and the wireless device.
