Method and apparatus for supporting event monitoring

A method for supporting event monitoring in a second apparatus, comprising:

• receiving from a first apparatus a first monitoring request message including a monitoring type parameter indicating a requested monitoring event to be monitored for one or a group of User Equipments (UEs);
• and
• sending to the first apparatus a first monitoring response message or a first monitoring indication message including a monitoring event report of the requested monitoring event of the one or group of UEs;
• wherein:
• the monitoring type parameter is a Packet Data Network (PDN) connectivity status parameter indicating a PDN connectivity status of the one or group of UEs;
• and
• the monitoring event report includes PDN connection information of the one or group of UEs;
• wherein:
• the PDN connection information includes a PDN connection status, a PDN type identifying a PDN connection type, and an interface indication identifying an interface between a 3GPP network and either a Service Capability Server (SCS)/Application Server (AS) or an Application Function (AF);
• and/or
• the PDN connectivity status includes a CREATED status indicating a PDN connection is created or includes a RELEASED status indicating a PDN connection is released;
• wherein one or more of:
• the PDN connection information further includes an Access Point name, at least one of a UE Internet Protocol (IP) version 4 (Ipv4) address or a UE IP version 6 (Ipv6) address, or both, wherein the UE Ipv6 address is replaced with a UE Ipv6 prefix if a ipv6 full address is unavailable;
• the PDN type includes an IP type indicating a PDN connection of IP type or includes a NON_IP type indicating a PDN connection of non-IP type;
• or
• the interface indication includes an Exposure function indicating a Service Capability Exposure Function (SCEF) or a Network Exposure Function (NEF) is used for a PDN connection towards an SCS/AS or an AF, or includes a PDN gateway indicating a PDN gateway is used for a PDN connection towards an SCS/AS or AF.

A first apparatus for supporting event monitoring, comprising:

• a transceiver configured to transmit wireless signals to a second apparatus and to receive wireless signals from the second apparatus;
• one or more processors;
• and
• one or more memories comprising a computer program configured to, when executed by the one or more processors, cause the first apparatus to:
• send to the second apparatus a monitoring request message including a monitoring type parameter indicating a requested monitoring event to be monitored for one or a group of User Equipments (UEs);
• and
• receive from the second apparatus a first monitoring response message or a first monitoring indication message including a monitoring event report of the requested monitoring event of the one or group of UEs;
• wherein:
• a value of the monitoring type parameter includes a Packet Data Network (PDN) connectivity status of the one or group of UEs;
• and
• the monitoring event report includes PDN connection information of the one or group of UEs;
• wherein:
• the PDN connection information includes a PDN connection status, a PDN type identifying a PDN connection type, and an interface indication identifying an interface between a 3GPP network and either a Service Capability Server (SCS)/Application Server (AS) or an Application Function (AF);
• and/or
• the PDN connectivity status includes a CREATED status indicating a PDN connection is created or a RELEASED status indicating a PDN connection is released;
• and
• wherein one or more of:
• the PDN connection information further includes an Access Point name, at least one of a UE Internet Protocol (IP) version 4 (Ipv4) address or a UE IP version 6 (Ipv6) address, or both, wherein the UE Ipv6 address is replaced with a UE Ipv6 prefix if a ipv6 full address is unavailable;
• the PDN type includes an IP type indicating a PDN connection of IP type or includes a NON_IP type indicating a PDN connection of non-IP type;
• or
• the interface indication includes an Exposure function indicating a Service Capability Exposure Function (SCEF) or a Network Exposure Function (NEF) is used for a PDN connection towards an SCS/AS or an AF, or includes a PDN gateway indicating a PDN gateway is used for a PDN connection towards an SCS/AS or AF.

• and
• send to the first apparatus a first monitoring response message or a first monitoring indication message including a monitoring event report of the requested monitoring event of the one or group of UEs;
• wherein:
• the monitoring type parameter is a Packet Data Network (PDN) connectivity status parameter indicating a PDN connectivity status of the one or group of UEs;
• and
• the monitoring event report includes PDN connection information of the one or group of UEs;
• wherein:
• the PDN connection information includes a PDN connection status, a PDN type identifying a PDN connection type, and an interface indication identifying an interface between a 3GPP network and either a Service Capability Server (SCS)/Application Server (AS) or an Application Function (AF);
• and/or
• the PDN connectivity status includes a CREATED status indicating a PDN connection is created or a RELEASED status indicating a PDN connection is released;
• and
• wherein one or more of:
• the PDN connection information further includes an Access Point name, at least one of a UE Internet Protocol (IP) version 4 (Ipv4) address or a UE IP version 6 (Ipv6) address, or both, wherein the UE Ipv6 address is replaced with a UE Ipv6 prefix if a ipv6 full address is unavailable;
• the PDN type includes an IP type indicating a PDN connection of IP type or includes a NON_IP type indicating a PDN connection of non-IP type;
• or
• the interface indication includes an Exposure function indicating a Service Capability Exposure Function (SCEF) or a Network Exposure Function (NEF) is used for a PDN connection towards an SCS/AS or an AF, or includes a PDN gateway indicating a PDN gateway is used for a PDN connection towards an SCS/AS or AF.
