Abstract
Embodiments of this application provide a method for selecting an access network type, a device, and a system, to flexibly select an access network type. An example method includes: determining, by a policy control function PCF entity, that a network status of a first network does not meet a preset condition, where the first network is a network currently accessed by a terminal; and sending, by the PCF entity, an access network type corresponding to a second network to the terminal, where the access network type corresponding to the second network is used to instruct the terminal to redirect a session of the terminal to the second network, and the second network is a network other than the first network.
Claims17
A method for selecting an access network type, wherein the method comprises:
- determining, by a policy control function (PCF) entity, that a network status of a first network does not meet a preset condition, wherein the first network is a network currently accessed by a terminal;
- and
- sending, by the PCF entity, an access network type corresponding to a second network to the terminal, wherein the access network type corresponding to the second network is used to instruct the terminal to redirect a session of the terminal to the second network, and the second network is a network other than the first network.
A policy control function (PCF) entity, wherein the PCF entity comprises:
- a processor;
- configured to determine that a network status of a first network does not meet a preset condition, wherein the first network is a network currently accessed by a terminal;
- and
- a transceiver, configured to send an access network type corresponding to a second network to the terminal, wherein the access network type corresponding to the second network is used to instruct the terminal to redirect a session of the terminal to the second network, and the second network is a network other than the first network.
A communications system, wherein the communications system comprises:
- a policy control function (PCF) entity, configured to determine that a network status of a first network does not meet a preset condition, wherein the first network is a network currently accessed by a terminal;
- and send an access network type corresponding to a second network;
- and
- a session management function (SMF) entity, configured to receive the access network type corresponding to the second network from the PCF entity, and send the access network type corresponding to the second network to the terminal, wherein the access network type corresponding to the second network is used to instruct the terminal to redirect a session of the terminal to the second network, and the second network is a network other than the first network.
