Systems, methods, apparatuses, and computer program products for policy control for broadcast sessions. One method may include receiving, by a multicast/broadcast session management function, at least one broadcast session creation request comprising at least one broadcast session indication associated with at least one policy control function. The multicast/broadcast session management function may receive at least one policy update from the at least one policy control function, and transmit at least one resource allocation request associated with at least one broadcast session transmission to at least one application management function.

The disclosure provides a method for assisting an unregistered user device to access private network services and a communication system. The method includes steps as follows. A request to access a private service of a private network is sent by a user device. In response to determining that the user device not registered on the private network wants to access the private service, the user device is assisted to obtain a temporary user profile by a mobile edge computing server through an emergency type attachment procedure. In response to determining that the user device is registered on the private network through the emergency type attachment procedure, a regular attachment procedure is executed by the user device based on the temporary user profile. In response to determining that the user device executes the regular attachment procedure, the mobile edge computing server provides the user device with the private service.

A method performed by a gateway node for handling application data traffic of a session between a UE and an application server in a wireless communications network is provided. Upon establishing the session, the gateway node obtains from a policy node, an identity identifying one or more rules provisioned for the UE. The identity is associated with the session and with a UP based API to be used for the session. The gateway node receives through the UP based API, a message from the UE. The message comprises the identity and a flow identifier identifying the application data traffic related to the identity. The message requests the one or more rules to be enforced by the gateway node. Upon detecting application data traffic associated with the flow identifier, the gateway node enforces the one or more rules, according to the obtained identity, for the detected application data traffic between the UE and the application server.

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 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.

A multi-tenant media processing platform system and method. At least a first media analysis service of a plurality of media analysis services is activated for at least a portion of an active communication session of an entity in the platform system. The first activated media analysis service performs a first media analysis on media of the active communication session that is collected by the platform system. The first activated media analysis service performs the first media analysis on the collected media while the communication session is active to generate a first media analysis result. During the active communication session, at least one media analysis result is applied.

Examples disclosed herein involve receiving a request from a calling device to establish a communication session between a mobile device and the calling device, the mobile device assigned a virtual telephone number, retrieving location information corresponding to a location of the mobile device from a location register, and sending a redirect to a session border controller (SBC) to establish the communication session between the calling device and the mobile device based on the location information.

Implementation of an application rule for an application to be accessed by a User Equipment, UE, in a user session in a Service Based Architecture, SBA, domain in a core network of a telecommunications system is disclosed. The SBA, among others, comprises a Policy Control Function, PCF (6), an Application Function, AF (5), and a Session Management Function, SMF (9). The method comprising the steps of receiving, by the PCF (6), an application rule comprising an AF Identifier, AF-ID, identifying the application rule, an Application Identifier, App-ID, identifying the application, and at least one service requirement for processing the application in the SBA domain. The PCF (6) instructing the SMF (9) to execute the at least one service requirement to all present and future user sessions pertaining to the respective application. Complementary methods of supporting the execution of the application rule and devices are also presented.

Embodiments of the present disclosure provide a method, an apparatus and a system for data connection management. The method for data connection management includes: obtaining, by a user equipment UE, first instruction information, wherein the first instruction information is used for instructing to close or open a data connection; and transmitting, by the UE, the first instruction information to a packet data network gateway P-GW, for enabling the P-GW to stop or start data transmission of at least one bearer of the UE according to the first instruction information.

A node of a charging system associated with a communication network grants a charging request, with the response including a granted quota of units for authorizing consumption of the involved communication service by a user device, along with an indication of whether the granted quota applies on an immediate basis or on a deferred basis. For example, the response indicates whether quota management is active for the involved communication service, with the granted quota applying immediately to consumption of the service if quota management is active and applying on a deferred basis if quota management is inactive. Providing a granted quota while quota management is inactive offers several advantages, such as proactively providing individual charging sessions with granted units of service consumption that may be used subsequently, upon quota management becoming active, thereby avoiding the “flood” of charging session requests that would otherwise be generated upon quota management becoming active.
