Abstract
Systems and methods are provided for managing load distribution in a telecommunications network. Specifically, a session management function (SMF) dynamically reallocates or redirects network sessions when the required load metric information is not received from a user plane function (UPF). The SMF utilizes control information and historical performance data to infer the operational status of the UPF and make real-time decisions to prevent network congestion and maintain service quality. This approach allows the SMF to continue managing network sessions efficiently, even in the absence of updated load metrics, ensuring the network remains stable and responsive under varying condition.
Claims20
A system for managing load distribution in a telecommunications network, the system comprising:
- one or more processors;
- one or more non-transitory computer readable media;
- and
- a session management function (SMF) embedded in the one or more one or more non-transitory computer readable media that, when executed by the one or more processors, cause the SMF to:
- receive load capacity information and control information from a plurality of user plane functions (UPFs);
- determine that the load capacity information and the control information has not been received from a first UPF of the plurality of UPFs within a predefined time period;
- query the first UPF for updated load capacity information in response to determining that the load capacity information has not been received and that the control information has been received within the predefined time period;
- determine that no updated load capacity information is received from the first UPF in response to the query;
- and
- reallocate one or more network sessions from the first UPF to a second UPF in response to the determination that no updated load capacity information is received.
A method for managing load distribution in a telecommunications network, the method comprising:
- requesting, by a session management function (SMF), load metric information and control information from a first user plane function (UPF);
- determining, by the SMF, that the load metric information has not been received and that the control information has been received from the first UPF within a first predefined time period;
- querying, by the SMF, the first UPF for updated load metric information in response to determining that the load metric information has not been received within the first predefined time period;
- and
- reallocating network sessions managed by the SMF in response to determining that the updated load metric information has not been received within a second predefined time period.
A non-transitory computer readable media having instructions stored thereon that, when executed by one or more computer processing components, cause the one or more computer processing components to perform a method for managing load distribution in a telecommunications network, the method comprising:
- receiving load capacity information and control information from a first user plane functions (UPFs);
- determining that load capacity information has not been received from the first UPF within a predefined time period;
- querying the first UPF for updated load capacity information in response to determining that the load capacity information has not been received within the predefined time period;
- determining that updated load capacity information has not been received from the first UPF in response to the query while continuing to receive control information from the first UPF;
- and
- reallocating network sessions based on the determination that updated load capacity information has not been received.
