A core network for mobile communication system is provided. The core network includes a first network function (NF) element, a second NF element, and an operations, administration and maintenance (OAM) element. The OAM element periodically transmits a resource quota status message to the second NF element to obtain a count number of the resource of first NF element and a limit value of the count number via the second NF element, and adjusts the limit value of the resource of the first NF element according to the count number and the limit value of the resource of the first NF element.

A system for multiple network usage tracking, the system having a policy management platform having one or more processors able to receive and to calculate account usage data associated with an account profile, the policy management platform arranged externally from a network of at least one wireless carrier.

This disclosure provides methods, services, and platforms that automatically prompt mobile phone users to add contact information to their phone book after a triggering event such as calling a phone number. The methods, services, and platforms allow mobile network operators to provide a service that allows businesses to potentially have their numbers added to the phonebook of a mobile phone after a disconnected call.

Systems and methods are provided for generating announcement information at a communication node. The method includes: generating a first announcement information associated with a first user; generating a second announcement information associated with a second user; and transmitting the first and second announcement information to a telephony application server, wherein the first announcement information and the second announcement information include at least one different element of data, further wherein both the first and second announcement information are used to generate or select announcements which are transmitted to the first and second users during a call between the first and second users.

Asynchronous and/or synchronous zero charge telephony protocol systems and methods may include an asynchronous signaling switch and/or a call duration time quota from a synchronous charging onset to place and complete a call. A first device call request is received with a second device mobile address. The asynchronous systems include instructions to automatically modify the mobile address with a routing prefix when the first device has insufficient balance or independent of balance, route to the asynchronous signaling switch based on an associated modified address trunk path, revert the modified call signal at the asynchronous signaling switch to the call signal, and deliver and automatically disconnect the call immediately when the call is completed. The synchronous systems include instructions to automatically set the call duration time quota upon insufficient balance, and deliver and automatically disconnect the call from the second user mobile device when the call is completed and the call duration time quota is exceeded.

The present disclosure is directed to using distributed ledger architectures. In one example, a distributed ledger system includes a first wireless provider and a second wireless provider configured to provide wireless services to one or more of end users of the first wireless provider to roam on; and a plurality of nodes associated with one or more of the wireless providers. Each of the plurality of nodes is configured to access a digital record of an exchange of wireless services between the first wireless provider and the second wireless provider; enable roaming of the one or more of the end users on the second wireless provider upon detecting a first triggering condition; monitor usage of the wireless services; verify the roaming based on the monitoring of the wireless services; and terminate the roaming of the one or more of the end users upon detecting a second triggering condition.

A policy control method performed by an enforcement function network element, where the enforcement function network element receives an update request to modify or remove a target packet flow description (PFD) associated with a target application identifier. For a session for which a first policy rule including the target application identifier is installed or activated, the enforcement function network element determines that data about an application corresponding to the target application identifier has been detected using the target PFD. The enforcement function network element further determines that start indication information of the application has been reported to a control function network element, and sends stop indication information of the application to the control function network element, which adjusts the first policy rule.

The embodiments herein relate to a method performed by a charging function (125) for handling a subscriber's communication services. The charging function (125) detects that a subscriber's credit account has reached or fallen below a credit threshold when the subscriber has multiple ongoing communication services consuming credit from the credit account. The charging function (125) sends a threshold notification to a UE (101) on which the subscriber has at least one of the multiple ongoing communication services. The charging function (125) determines if a response to the threshold notification has been received with prioritization of one of the multiple ongoing communication services. If a response with prioritization of one communication service has been received, the charging function (125) initiates termination of all ongoing communication services except the prioritized communication service, and provides all available credit to be available for the prioritized communication service.

Systems and methods of providing policy and charging control in an information-centric network are described. An interest packet is transmitted from a content consumer to a holder through a gNB, ICN-PoA and ICN-GW. The interest packet has a prefix identifying content to be retrieved and a type field indicating an interest packet. The ICN-PoA modifies the interest packet to include a type of service (TS) field having the identity of the consumer and then transmitted to the ICN-GW when the content is neither created nor cached inside the 5G network. A data packet that includes the prefix, a type field indicating a data packet and the TS field is returned from the ICN-GW. The data packet is modified by the ICN-PoA to remove the TS field and transmitted to the consumer. The interest and data packets are logged and reported to an ICN-CF for generation of charging records.
