Abstract: One aspect can provide a system and method for enforcing a single-domain registration of a user equipment (UE) roaming across different provider networks. During operation, the system can receive, at a subscriber-management entity (SME) from a first service node within a first provider's network, a location-update message associated with the UE. The system can identify a second service node within a second provider's network with which the UE has a previous registration and query a subscriber-information database to determine whether a single-domain-registration feature is enabled at the SME for the UE. In response to determining that the single-domain-registration feature is enabled, the system can send a location-cancellation message to the second service node to cause the second service node to cancel the previous registration of the UE and register the UE at the SME.

Abstract: The systems and method disclosed herein optimize the deregistration of user equipment (UE) from the 5GC. For example, when the UE operates in single-registration mode, for AMF 3GPP access registration with drFlag attribute set to false (or to be absent) in UDM/UDR, a “new attribute”, singleRegIndication, is defined. The AMF sets the singleRegIndication value to “NO_INDICATION” when there is no N26 interface connection to MME. UDM will not instruct HSS to cancel MME (and SGSN/VLR) if there is an old AMF 3GPP registration for which “NO_INDICATION” or “DEREGISTER_SN” is set as the singleRegIndication value (i.e. the old AMF was already registered with the single registration). Otherwise, the AMF sets the singleRegIndication value to “DEREGISTER_SN” when the AMF has established a N26 interface connection to the old MME. UDM can instruct HSS to cancel the MME (and SGSN/VLR).

Abstract: In some examples, a computer-readable medium includes instructions. The instructions may be executable by a processing resource to maintain a default roaming restrictions database that stores default roaming restriction attributes specific to roaming classes of service defined by a network operator. The default roaming restriction attributes may be specific to the roaming classes of service independent of mobile country code and mobile network code. The instructions may also be executable by the processing resource to perform a lookup into the default roaming restrictions database to identify a particular default roaming restriction attribute specific to a particular roaming class of service defined by the network operator.

Abstract: Examples relate to determining mobile network class of service. In one example, a computing device may receive, from a mobility management entity (MME), a request from a device that requested access to a network operated by the MME, the request specifying an account identifier and location data that corresponds to the device; based on the location data, determine that the device is roaming; based on the account identifier and in response to the determination that the device is roaming, identify a class of service (CoS) for the device; and provide the MME with response data including the identified CoS.

Abstract: 5G provides for interworking with the 4G/LTE networks, which provides for mobility of user equipment between the 5G and 4G/LTE networks. Mobility from 5G to 4G/LTE requires deregistering user equipment from the 5G core network (5GC) by communicating a deregistration notification from the Evolved Packet Core (EPC) to the 5GC. Systems and methods disclosed herein provide for an optimized deregistration process through avoidance of redundant deregistration notification traffic injected into the 5G network by utilizing 4G/LTE connectivity information to determine whether or not to inject deregistration notifications into the 5G network.
