Systems and methods for dynamically collecting information regarding network events in a 5G network are disclosed. The method includes locally storing event data initially and implementing post-event collection of the locally stored data when one or more collecting nodes become available.

Systems and methods are described herein for performing automated testing of online charging systems associated with telecommunications networks. In some embodiments, the systems and methods utilize various components associated with an online charging system, such as an event mediator, to convert data associated with test cases to be simulated by the online charging system (e.g., data from spreadsheets) into various test requests actionable during the online charging system under when simulating the test cases.

A control device according to an embodiment includes a calculator, a changing unit, and a transmitter. The calculator calculates a first communication volume obtained by adding a value obtained by normalizing a communication volume of a voice call of a first terminal and a value obtained by normalizing a communication volume of data communication of the first terminal on the basis of a first history of the voice call of the first terminal and a second history of the data communication of the first terminal. The changing unit changes a first upper limit of a third priority obtained by adding a first priority set to the voice call of the first terminal and a second priority set to the data communication of the first terminal on the basis of the first communication volume.

A method is disclosed for downscaling a deep packet inspection service in a network apparatus. The method comprises receiving data flow in a gateway virtual machine via a software defined networking switch, and keeping track of data flow and control flow and their state per subscriber. If needed, a new deep packet inspection virtual machine is selected for the data flow. The software defined networking switch is informed on the selection of the new deep packet inspection virtual machine. The new deep packet inspection virtual machine is instructed to re-create a flow identification for the data flow to ensure deep packet inspection service continuity.

A method is performed by at least one processor in a network node operating in a wireless communication network. The method includes receiving, from at least one user equipment (UE), a data stream including one or more data packets associated with an uplink transmission between the UE and the network node. The method further includes analyzing the data stream to determine whether the at least one UE transmitted one or more data packets not received by the network node. The method further includes, in response to determining the at least one UE transmitted the one or more data packets not received by the network node, performing a corrective action on the data stream. The method further includes completing the uplink transmission based on the data stream after the corrective action is performed.

A first charging data record (CDR) generating node can receive charging server information and available CDR storage information from a second CDR generating node. The first CDR generating node can detect that the charging server is unavailable to receive CDRs from the first CDR generating node. The first CDR generating node can also determine that a CDR storage area corresponding to the first CDR generating node should not be used to store additional CDRs. The first CDR generating node can also select the second CDR generating node for storing the additional CDRs that are generated by the first CDR generating node. The second CDR generating node can be selected based at least in part on the charging server information and the available CDR storage information. The first CDR generating node can cause at least one CDR to be sent to the second CDR generating node.

A charging processing method includes: when a charging processing device for a user service is unavailable, storing charging data of the user service during the failure period, where the charging data includes charging data that is not sent or charging data that is not processed; and after it is determined that a charging processing device for the user service transitioned from unavailable to available, sending a charging request message that includes the charging data during the failure period to the available charging processing device, so that the available charging processing device performs charging processing on the charging data before a charging processing device transitioned to available. In this method, when the charging processing device or a network is faulty, interruption of the user service can be avoided, and a loss caused for an operator can be avoided.

The present invention provides apparatuses, methods, and computer program products regarding overload control handling in case of an overload state of a charging entity. The method comprises controlling a charging control session with a charging entity, receiving an overload report from the charging entity, and preventing to send any charging related request messages to the charging entity until a predetermined period has elapsed.

A data packet processing method and apparatus is disclosed. According to the method, a storage apparatus disposed on a network side stores a correspondence between an identifier and data flow characteristic information. When configuring a policy for a data packet including a first identifier, a network-side device requests the storage apparatus for data flow characteristic information corresponding to the first identifier. A PCEF receives a data packet that is sent by UE, matches the data packet against the data flow characteristic information, and when the data packet matches the data flow characteristic information, executes a policy on the data packet according to policy information corresponding to the first identifier. According to the method provided in embodiments of the present disclosure, transmitting a considerable amount of data flow characteristic information on an interface of an SCEF is avoided, and load on the SCEF is relieved.
