Abstract
Methods and apparatuses for mobility between different communication systems are disclosed. According to an embodiment, a session management function (SMF) sends, to a service provider, a request for registering information related to the SMF to the service provider. The information related to the SMF comprises information indicating or derived from an Internet protocol (IP) address of a packet data network (PDN) gateway (PGW) control plane (PGW-C) that is combined together with the SMF. The SMF receives, from the service provider, a response to the request.
Claims20
A method performed by a service provider, the method comprising:
- receiving, from a session management function (SMF), a request for registering information related to the SMF to the service provider, wherein the information related to the SMF comprises information indicating or derived from an Internet protocol (IP) address of a packet data network (PDN) gateway (PGW) control plane (PGW-C) that is combined together with the SMF, wherein the information indicating or derived from the IP address of the PGW-C is the IP address as an octet string filled in an information element called “PGW fully qualified domain name, FQDN”;
- and
- sending, to the SMF, a response to the request.
A method performed by a service provider, the method comprising:
- providing, to a service consumer, current or updated subscription information of a terminal device;
- wherein the current or updated subscription information of the terminal device comprises information indicating or derived from an Internet protocol (IP) address of a packet data network (PDN) gateway (PGW) control plane (PGW-C) that is combined together with a session management function (SMF), wherein the information indicating or derived from the IP address of the PGW-C is the IP address as an octet string filled in an information element called “PGW fully qualified domain name, FQDN”.
A service provider comprising:
- at least one processor;
- and
- at least one memory, the at least one memory containing instructions executable by the at least one processor, whereby the service provider is operative to:
- receive, from a session management function (SMF), a request for registering information related to the SMF to the service provider, wherein the information related to the SMF comprises information indicating or derived from an Internet protocol (IP) address of a packet data network (PDN) gateway (PGW) control plane (PGW-C) that is combined together with the SMF, wherein the information indicating or derived from the IP address of the PGW-C is the IP address as an octet string filled in an information element called “PGW fully qualified domain name, FQDN” and
- send, to the SMF, a response to the request.
A service provider comprising:
- at least one processor;
- and
- at least one memory, the at least one memory containing instructions executable by the at least one processor, whereby the service provider is operative to:
- provide, to a service consumer, current or updated subscription information of a terminal device;
- wherein the current or updated subscription information of the terminal device comprises information indicating or derived from an Internet protocol (IP) address of a packet data network (PDN) gateway (PGW) control plane (PGW-C) that is combined together with a session management function (SMF), wherein the information indicating or derived from the IP address of the PGW-C is the IP address as an octet string filled in an information element called “PGW fully qualified domain name, FQDN”.
