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.

Single-domain registration initiated cancellation

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.

Optimized deregistration interworking

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.

Determining mobile network class of service

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.

Default roaming restrictions specific to roaming classes of service

A subscriber record may include a plurality of references to a plurality of specific class of service records. Each class of service record may relate to a different type of customized applications service subscriber information.

Subscriber record referencing class of service records

A method and corresponding apparatus and system of controlling access to communication services by a roaming wireless device are described. The method includes receiving a request for roaming wireless device service information related to a roaming user and determining which services the user has access to for the requesting system, if the user is determined to have access to the requesting system. The method also includes transmitting user service information concerning the services to which the user has access. The apparatus includes a memory, a communication system, and a processor. The memory stores: (1) user information including a class of service (COS) identifier and (2) COS restriction information. The processing system, coupled with the communication system and the memory, generates a reply message based on comparing information in a service request message received by the communication system with the stored information in the memory.

Controlling access to communication services

System and method for traffic surge control. A control message may be received for registering or managing a device in a network. A measure of a number of current control messages already being processed in the network may be retrieved. A condition may be retrieved, from among a plurality of conditions, that corresponds to the retrieved measure of current control messages, each condition defining different rules for discarding a control message of the same type and corresponding to one of a plurality of measures of current control messages. Based on whether or not the retrieved condition is met, the control message may be processed to register or manage the device or discarded.

System and method for traffic surge control

Systems, methodologies, media, and other embodiments associated with provisioning an Internet Protocol (IP) core network services multimedia subsystem (IMS) are described. One exemplary system embodiment includes a Home Subscriber Server (HSS) logic operably connectable to components including, a user database, an application server (AS), and a permissions database. The HSS logic may be a component of an IMS that facilitates communications between application servers and users. Thus, the HSS logic may be configured to receive an AS-to-user-database-interface-message (AUDIM) and to selectively update the permissions database based, at least in part, on the AUDIM. The user database may store user data concerning IMS users and the permissions database may store information for controlling AUDIM initiated interactions between an AS and the user database.

Automated application server (AS) permissions provisioning

Systems, methodologies, media, and other embodiments associated with provisioning an internet protocol (IP) multimedia core network subsystem (IMS) are described. One exemplary system embodiment includes logic for provisioning an IMS charging database with charging data and logic for provisioning an IMS user database with user data. The exemplary system embodiment may also include logic for provisioning an IMS call session control function (CSCF) logic with data that relates a user to charging information based, at least in part, on a charging class of service (COS) identifier.

Charging database with class of service (COS)

Systems, methodologies, media, and other embodiments associated with provisioning an internet protocol (IP) multimedia core network subsystem (IMS) are described. One exemplary system embodiment includes logic for provisioning an IMS application server (AS) database with AS data and logic for provisioning an IMS user database with user data. The exemplary system embodiment may also include logic for provisioning an IMS initial filter criteria (IFC) database with data that relates a user to an AS based, at least in part, on an AS class of service (COS) identifier.

Application server (AS) database with class of service (COS)

Systems, methodologies, media, and other embodiments associated with provisioning an internet protocol (IP) multimedia sub-system (IMS) are described. One exemplary system embodiment includes logic for provisioning an IMS initial filter criteria (IFC) database with IFC data and logic for provisioning an IMS user database with user data. The exemplary system embodiment may also include logic for provisioning an IMS call session control function (CSCF) logic with data that relates user data to IFC data based, at least in part, on a class of service (COS) identifier.

Initial filter criteria (IFC) database with class of service (COS)

Systems, methods, and devices for a database are provided. One database embodiment includes a set of executable instructions operable on the database. One or more database partitions are provided, each having a defined key range. The set of executable instructions is operable to reverse octets in variable length keys. A last digit in an odd-length key value, plus a pad, is placed in a dedicated octet to partition the variable length keys in the one or more database partitions.
