Abstract: A method for detecting and mitigating effects of abnormal MTC device behavior includes, at a telecommunications network node comprising one of an MME, DRA, or SCEF, receiving CP information from which core network (CN) assistance information for tuning an evolved node B (eNB) to minimize MTC device state transitions is derivable, forwarding the CP information or CN assistance information derived from the CP information to another network node, deriving, from the CP information, a rule for policing behavior of the MTC device, storing the rule in memory of the telecommunications network node, monitoring uplink communications from the MTC device, determining, using the stored rule derived from the CP information, that the MTC device is not behaving in accordance with an expected behavior; and, in response performing a network security action that mitigates an effect of traffic from the MTC device on the network.

Abstract: Methods, systems, and computer readable media for sharing identification information of network nodes in an IMS network are disclosed. One method includes determining, by a packet data network gateway (PGW), policy and charging rules function (PCRF) identification information corresponding to a PCRF node designated to support an IMS-based subscriber session requested by a user equipment device and establishing, by the PGW, a subscriber Gx session with the PCRF node corresponding to the determined PCRF identification information. The method further includes determining, by the PGW, application function (AF) identification information corresponding to an AF server designated to support the IMS-based subscriber session and generating, by the PGW, a create session response message including at least the PCRF identification information and the AF identification information. The method also includes sending, by the PGW, the create session response message containing the at least the PCRF identification inform.

Abstract: A method for supporting multiple locations in a preferred-locality attribute NF discovery and selection includes receiving, from producer NFs, NF registration messages including NF profiles with locality attributes and registering the producer NFs by storing the NF profiles including the locality attributes in an NF registration database local to an NRF. The method further includes receiving, from a requesting NF, an NF discovery request having query parameters for discovering producer NFs, the query parameters including a preferred-locality attribute identifying a plurality of different preferred producer NF locations. The method further includes retrieving NF profiles from the NF registration database having locality attributes that match any of the preferred producer NF locations. The method further includes generating an NF discovery response including the NF profiles retrieved from the NF registration database. The method further includes forwarding the NF discovery response to the requesting NF.

Abstract: A method for feedback-based network slice management includes steps performed at a network slice management function (NSMF) including at least one processor. The steps include subscribing, via a network data analytics function (NWDAF) subscription interface of the NSMF, directly with the NWDAF to create a subscription to be notified of network slice load information and specifying, as part of the subscription, network slice load information report generation criteria defined by the NSMF. The steps further include receiving, directly from the NWDAF, via the NWDAF subscription interface of the NSMF and in response to the NSMF-defined network slice load information report triggering criteria being met, network slice load information. The steps further include determining, based on the network slice load information, that a network slice resource allocation change is needed. The steps further include, in response to determining that a network slice resource allocation change is needed, dynamically changing the network slice resource allocation during operation of a network slice.

Abstract: A method for dynamically provisioning and using PLMN location mappings includes, in an SCEF or NEF, receiving, from a PLMN network node, a message containing a PLMN location identifier and a non-PLMN location identifier, extracting the PLMN location identifier and the non-PLMN location identifier from the message and storing, in a PLMN location mapping database in the SCEF or NEF, a mapping between the PLMN location identifier and the non-PLMN location identifier. The method further includes receiving, via a monitoring interface of the SCEF or NEF, a monitoring request message requesting IoT device information and including a non-PLMN location identifier. The method further includes locating an entry in the PLMN location mapping database corresponding to the non-PLMN location identifier, extracting a PLMN location identifier from the database, using the PLMN location identifier extracted from the database to obtain IoT device information, and responding to the monitoring request message with the IoT device information.
