Abstract
A method for determining an IP address of a 5G user terminal is disclosed. A SMF determines a target DNN matching the SMF and a type of a terminal address pool for the target DNN. For dynamic configuration, the SMF configures a first UPF and a second UPF in a load balancing mode, and the first UPF or the second UPF selects an IP address from respective IP address pools as a dynamic IP address of the user terminal accessing the target DNN. For fixed acquisition, the SMF configures the first UPF and the second UPF in an active-standby mode, and the first UPF or the second UPF as an active apparatus determines a fixed IP address of the user terminal accessing the target DNN from the respective IP address pool.
Claims10
A method for determining an Internet Protocol (IP) address of a 5G user terminal, applied to a system for determining an IP address of a 5G user terminal, wherein the system for determining an IP address of a 5G user terminal comprises a first User Plane Function (UPF) and a second UPF, and the method comprises:
- determining, by a Session Management Function (SMF) and according to preset configuration information, a target Data Network Name (DNN) that matches with the SMF, and determining a type of a terminal address pool configured for the target DNN;
- in response to the type of the terminal address pool configured for the target DNN being a dynamic configuration, configuring, by the SMF, the first UPF and the second UPF in a load balancing mode to allocate IP addresses of the terminal address pool to the first UPF and the second UPF in a preset proportion, and selecting, by the first UPF or the second UPF, an IP address from respective IP address pools as a dynamic IP address of the user terminal accessing the target DNN, wherein the user terminal is capable of establishing a Protocol Data Unit (PDU) session with the first UPF or the second UPF through the dynamic IP address;
- and
- in response to the type of the terminal address pool configured for the target DNN being a fixed acquisition, configuring, by the SMF, the first UPF and the second UPF in an active-standby mode to allocate the terminal address pool to both the first UPF and the second UPF, and determining, by one of the first UPF and the second UPF which is configured as an active apparatus, a fixed IP address of the user terminal accessing the target DNN from the respective IP address pool, wherein the user terminal is capable of establishing the PDU session with the active apparatus through the fixed IP address.
An apparatus for determining an IP address of a 5G user terminal, comprising:
- an allocation determination unit configured to determine, by a Session Management Function (SMF) and according to preset configuration information, a target Data Network Name (DNN) that matches with the SMF, and determine a type of a terminal address pool configured for the target DNN;
- a first processing unit configured to, in response to the type of the terminal address pool configured for the target DNN being a dynamic configuration, configure, by the SMF, the first UPF and the second UPF in a load balancing mode to allocate IP addresses of the terminal address pool to the first UPF and the second UPF in a preset proportion, and to select, by the first UPF or the second UPF, an IP address from respective IP address pools as a dynamic IP address of the user terminal accessing the target DNN, wherein the user terminal is capable of establishing a PDU session with the first UPF or the second UPF through the dynamic IP address;
- and
- a second processing unit, configured to, in response to the type of the terminal address pool configured for the target DNN being a fixed acquisition, configure, by the SMF, the first UPF and the second UPF in an active-standby mode to allocate the terminal address pool to both the first UPF and the second UPF, and to determine, by one of the first UPF and the second UPF which is configured as an active apparatus, a fixed IP address of the user terminal accessing the target DNN from the respective IP address pool, wherein the user terminal is capable of establishing the PDU session with the active apparatus through the fixed IP address.
A system for determining an IP address of a 5G user terminal, comprising:
- a first User Plane Function (UPF) in communication connection to the user terminal and a data network respectively;
- a second UPF in communication connection to the user terminal and the data network respectively;
- and
- at least one Session Management Function (SMF) connected to the first UPF and the second UPF respectively, and configured to configure the first UPF and the second UPF according to a type of a terminal address pool configured by a Data Network Name (DNN), wherein the type of the terminal address pool comprises a dynamic configuration and a fixed acquisition, and in the dynamic configuration, the SMF configures the first UPF and the second UPF in a load balancing mode, and in the fixed acquisition, the SMF configures the first UPF and the second UPF in an active-standby mode, the first UPF is an active apparatus, the second UPF is a standby apparatus, and the user terminal preferentially establishes a PDU session through the active apparatus.
