Abstract: A policy and charging rules function (PCRF) stores a policy rule management table in which a policy rule corresponding to a combination of contract information and a device type is registered and a hierarchical management table in which user information including contract information of a user and information on the device are managed in association with each other, acquires the device type serving as an application target of the policy rule, and a device ID assigned to the device, determines the policy rule according to the acquired device type and the contract information of the user, and instructs a deep packet inspection (DPI) to apply the determined policy rule to the device corresponding to the acquired device ID. The DPI acquires the device ID, and applies the policy rule to communication from the device corresponding to a device ID assigned to the device, and performs control.

Abstract: Techniques for flexible electronic subscriber identity module (eSIM) deployment to a wireless device by a network server, including generation of multiple eSIMs using an identical eSIM identifier value, such as an identical integrated circuit card identifier (ICCID) value, and subsequent selection of an eSIM based on capabilities of the wireless device. Multiple eSIMs that correspond to different sets of wireless device capabilities are generated without knowledge of the wireless communication standards that a wireless device supports. The multiple eSIMs include a first eSIM that includes fifth generation (5G) wireless communication protocol information and a second eSIM that excludes 5G wireless communication protocol information. The network server selects an eSIM from the multiple eSIMs based on whether the wireless device is 5G capable.

Abstract: A network services provider delivers bandwidth services to users in relation to a dynamic limit based on an average user consumption, rather than a fixed amount per subscriber. An average user consumption is employed to compute a consumption limit from relative portions of a user community substantially exceed the average, typically defined as “heavy users.” Usage levels below the consumption limit have an increased availability up to the consumption limit. The consumption limit may vary from a total capacity of the service infrastructure, which changes, generally in an increasing manner, as additional resources are added to the network. The consumption limits may be defined over different service intervals, such as daily, weekly or monthly, and for different groups of users depending on network layout.
