Claims12
A method for identifying a change of status of a session management function (SMF) within a network environment comprising:
- detecting or receiving at a network resource function (NRF), an indication of a change in a status of a SMF including a time at which the change in the status of the SMF occurred;
- identifying one or more resources lost to the SMF by determining a set of network resources associated with the SMF prior to the time;
- changing, in the NRF, an attribute associated with the one or more resources to indicate a status of suspended, wherein the attribute comprises at least one of an NFStatus attribute or an NFServiceStatus attribute of a profile associated with the SMF;
- and
- notifying a subscribed network function of the change in status of the SMF, wherein the subscribed network function is an Access and Mobility Function (AMF) or a Policy Control Function (PCF).
An apparatus for identifying a change of status of a SMF within a network environment, the apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:
- detect or receive an indication of a change in a status of a SMF including a time at which the change in the status of the SMF occurred;
- identify one or more resources lost to the SMF by determining a set of network resources associated with the SMF prior to the time;
- change an attribute associated with the set of network resources to indicate a status of suspended, wherein the attribute comprises at least one of an NFStatus attribute or an NFServiceStatus attribute of a profile associated with the SMF;
- and
- notify a subscribed network function of the change in status of the SMF, wherein the subscribed network function is an Access and Mobility Function (AM F) or a Policy Control Function (PCF).
A non-transitory computer-readable storage medium for identifying a change of status of a session management function (SMF) within a network environment, the non-transitory computer-readable storage medium storing program code instructions that, when executed, cause an apparatus to:
- detect or receive an indication of a change in a status of a SMF including a time at which the change in the status of the SMF occurred;
- identify one or more resources lost to the SMF by determining a set of network resources associated with the SMF prior to the time;
- change an attribute associated with the set of network resources to indicate a status of suspended, wherein the attribute comprises at least one of an NFStatus attribute or an NFServiceStatus attribute of a profile associated with the SMF;
- and
- notify a subscribed network function of the change in status of the SMF, wherein the subscribed network function is an Access and Mobility Function (AM F) or a Policy Control Function (PCF).
