    Abstract: The embodiments of the present invention provide a method and system for realizing an emergency communication service and corresponding apparatuses thereof. The realization method includes: a radio network side receiving a message carrying an emergency service indication sent by a user terminal; and establishing a bearer link for bearing emergency service signaling and emergency service data for the user terminal; the radio network side receiving an address obtaining request message sent by the user terminal based on the bearer link for bearing emergency service signaling; and sending down to the user terminal a local network communication address allocated for the user terminal and an access point address to an apparatus providing a local network emergency service based on the bearer link for bearing the emergency service signaling; the user terminal realizing communication with the apparatus providing a local network emergency service according to the access point address down sent by the network side based on the communication address and the established bearer link down sent by the radio network side. The embodiments of the present invention can realize an ability of providing emergency communication service procession for the user based on a radio network system.

    Abstract: A service flow processing method and system and a method and system for associating a bear are provided to make clear of the associated processes in the service flow after incorporating the WiMAX network with the PCC framework. In the methods, a PCRF generates a PCC rule according to a policy decision(307A), after receiving a PCC rule request(304A), then provides the PCC rule and an authorized QoS to a PCC policy enforcement function entity in the WiMAX network(309A), and the PCC policy enforcement function entity performs the QoS policy control and charging (310A) according to the received PCC rule and authorized QoS. The various corresponding flows in the service process includes a preset stream establishment flow, a service establishment flow, a service modification flow and service deletion flow, etc.. The flows makes clear of the associated processes in the service flow relating to the WiMAX network after incorporating the WiMAX network with the PCC framework.
