The AAA server generates and delivers a new HA-RK before expiry of the old HA-RK, thus eliminating the time gap between expiry of the old HA-RK and obtaining of the new HA-RK and making the MIP registration seamless. In the system, if the remaining lifetime of the old HA-RK is less than or equal to the lifecycle of the MSK in the EAP process, a new HA-RK is delivered; otherwise, no new HA-RK needs to be delivered. If both a new HA-RK and an old HA-RK are valid on the network entity at a time, then only the old HA-RK applies and the new HA-RK is not active until expiry of the old HA-RK. Alternatively, both the new HA-RK and the old HA-RK are active concurrently, and are differentiated by an SPI.

A system and charging control method of network convergence policy and charging control architecture are disclosed, based on the QoS parameter, charging policy and user subscribing information granted by the service layer, the PCRF confirms PCC rule, and provides the PCC rule to the policy distribution function PDF. As the interface between the PCRF and PCC policy performing entity, the PDF performs the protocol conversion and information distribution. Based on the PCC rule, the PCC policy performing entity performs QoS policy of the service data flow and the detecting and charging of the service flow.

A method and a system for setting up header compression communication and a header compression policy function entity are disclosed herein. The method includes: a header compression enforcement function entity receives a header compression indication from a header compression policy function entity; and the header compression enforcement function entity negotiates header compression channel parameters with the other corresponding header compression enforcement function entity to set up header compression channel. A communication system and a header compression policy function entity are disclosed. The embodiments of the present disclosure overcome the failure of implementing the header compression communication in the prior art.

A method for a terminal to join a multicast broadcast service (MBS) in a wireless network and a wireless communication system are provided, so as to enable a terminal to successfully join an MBS and receive MBS content. The method and the system relate to a wireless communication field. A terminal obtains MBS parameters that include a first ID indicating an air interface connection and a second ID indicating MBS content from a network, so that the terminal can receive the MBS content indicated by the second ID from the air interface connection indicated by the first ID after receiving the MBS parameters and thus successfully join the MBS. The terminal may initiate an MBS join process by sending an MBS join request message, so as to obtain the MBS parameters and join the required MBS. The network may actively initiate the MBS join process to send the MBS parameters to the terminal and invite the terminal to join the MBS.
