Techniques and systems for recovering a communication session from a dedicated bearer failure are disclosed. For example, a P-CSCF node can determine that a dedicated bearer associated with a communication session has failed, and, in response, send a SIP message to a UE associated with the communication session, the SIP message causing the UE to refrain from sending SIP requests using a SIP INVITE method. The process may further include identifying a first network node associated with an identifier of the UE, the first network node comprising one of a PGW or a SMF, and sending an instruction to the first network node to dissociate the dedicated bearer from the communication session. This causes a new attach procedure to be performed by the UE to recover the session without session failure.

A device may create a list of identifiers for base stations that support a fixed wireless service for a user device. The device may receive a first identifier of a first base station associated with a first attach request of the user device. The device may enable the fixed wireless service for the first base station for the user device when the first identifier is included in the list of identifiers. The device may disable the fixed wireless service for the first base station for the user device when the first identifier is not included in the list of identifiers.

The present application relates to devices and components including apparatus, systems, and methods for ephemeris signaling in wireless networks.

A computer-implemented billing method including displaying, on a video call screen, video data related to a counterpart terminal with which a video call is connected, recognizing reaction information input from the counterpart terminal based on the video data related to the counterpart terminal displayed on the video call screen, and generating billing data related to the recognized reaction information of the counterpart terminal based on a billing policy may be provided.

An optimization apparatus (100) includes a setting unit (110) that sets a predetermined non-linear objective function, a policy determination unit (120) that determines a policy to be executed in online optimization in a bandit problem, based on the non-linear objective function, a policy execution unit (130) that acquires a reward as an execution result of the determined policy, an update rate determination unit (140) that determines an update rate of the non-linear objective function by a multiplicative weight update method, based on the acquired reward and the non-linear objective function, and an update unit (150) that updates the non-linear objective function, based on the update rate.

A method in a network node comprises: detecting a Quality of Service (QoS) Violated Event in respect of a particular QoS flow of a Protocol Data Unit (PDU) session; and sending a corresponding QoS violated event report to any one or more of: a Session Management Function (SMF) of the network; a Policy Control Function (PCF) of the network; an Application Function (AF) of the network; and a third party service provider.

Embodiments of the present disclosure describe systems, devices, and methods for charging architectures in cellular networks. Various embodiments may include an eNB collecting information about licensed and unlicensed spectrum resource usage on a per bearer basis and transmitting the information to a core network node. Other embodiments may be described or claimed.

The disclosure relates in some aspects to establishing connectivity with a network using a first set of credentials and determining whether additional connectivity needs to be established (e.g., using a second set of credentials) to communicate data. The disclosure relates in some aspects to the use of multiple credentials for access and service connectivity. For example, traffic generated by a device may be authorized based on a different set of credentials than the set of credentials used to access the network (e.g., to connect to an LTE network for a PDN connection). In this way, traffic belonging to a specific service or application can be charged and policed based on service specific needs. The disclosure thus relates in some aspects to the use of access credentials and service credentials. These different types of credentials can be used to enable traffic differentiation and policing based on the credentials in use.

The present system relates to a server for providing data connectivity in a packet mode communication network. The server has a processor arranged to receive, via a first brokerage control unit, a charging rule request to allow one or more communication devices in the communication network to exchange with an application server data charged under operator specific billing. The server determines availability of the operator specific billing based on network parameters and the charging rule request, and updates the database of a Policy and Charging Rules Function (PCRF) entity in the communication network based on available operator specific billing and an identifier for the application server, for subsequent charging of data exchanged with the application server at said available operator specific billing.

Embodiments of the present disclosure disclose a service processing method, a PCRF, and a system. The method performed by the PCRF includes: obtaining service information of a service, where the service information includes a service identity; obtaining, according to user information and the service information, information indicating that the service requires QoS guarantee, and service chain information; when determining, according to the service chain information, that a network resource occupied by the service may be changed, sending the service identity and the information indicating that the service requires the QoS guarantee to a value-added service processor; receiving target service information, returned by the value-added service processor, of the service corresponding to the service identity; generating a first control policy according to the target service information; and sending the first control policy to a PCEF, so that the PCEF reserves a first network resource according to the first control policy.
