  • the entity sends a service authorization request to the MBS service management entity and the user management entity by the MBS proxy entity proxy GW.
  • the MBS server may first send a service authorization response message to the MBS proxy entity, and the MBS proxy entity performs the execution of the MBS service quality policy in the ASN and the PCC rule split, and then splits.
  • the subsequent PCC policy is sent to other policy enforcement points in the ASN for execution.
  • the specific process of the MBS bearer setup process and the QoS execution process in the implementation example of the present invention is as follows:
  • Step 1201 The MBS server sends a bearer setup indication message to the gateway.
  • Step 1202 After receiving the bearer setup indication message, the gateway performs the QoS policy and the service flow authorization.
  • Step 1203 The gateway sends a bearer setup response to the MBS server.
  • Step 1204 After receiving the bearer setup response, the MBS server establishes a bearer with the gateway.
  • Step 1206 The base station allocates air interface resources.
  • the multicast broadcast MBS service information is obtained by the PCRF entity, and the MBS service information and the local network policy information are used to generate a policy control and charging PCC rule; the MBS policy enforcement entity obtains and installs and executes the PCC. rule. Therefore, in the MBS service establishment process, and when the terminal joins the MBS IP multicast group, the method of the embodiment of the present invention can be used to implement the control of the MBS service, so that the MBS service can be controlled by the unified PCC architecture, thereby solving the problem.
  • the PCC architecture is used to implement policy control and charging control in the basic process of MBS service establishment, such as: MBS service flow authorization, QoS control, charging control, and MBS service flow detection.

Abstract

Procédé, système et dispositif de commande pour service de diffusion et de multidiffusion (MBS). La démarche consiste: à obtenir des informations sur le service de diffusion et de multidiffusion, à utiliser cette information pour l'autorisation du service et à créer une règle de politique et de gestion de la facturation (PCRF) et à diffuser cette règle auprès de l'entité d'exécution de la stratégie de diffusion et de multidiffusion (MBS) pour mise en oeuvre et application.
