20090219850 | METHOD FOR TERMINAL TO JOIN MULTICAST BROADCAST SERVICE IN WIRELESS NETWORK AND SYSTEM USING THEREOF - 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. | 09-03-2009 |
20090279704 | MOBILE INTERNET PROTOCOL SYSTEM AND METHOD FOR UPDATING HOME AGENT ROOT KEY - A MIP system and a method for updating an HA-RK are disclosed. 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. | 11-12-2009 |
20100048161 | METHOD, SYSTEM AND APPARATUSES THEREOF FOR REALIZING EMERGENCY COMMUNICATION SERVICE - A method and a system for realizing an emergency communication service and apparatuses thereof are provided. The method includes: receiving a message carrying an emergency service indication sent by a user terminal; establishing a bearer link for bearing emergency service signaling and emergency service data; receiving an address obtaining request sent by the user terminal based on the bearer link for bearing the emergency service signaling; delivering 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; and realizing communication with the apparatus providing a local network emergency service according to the access point address and based on the communication address and the established bearer link. Thus, an emergency communication service processing capability is achieved for the user based on a radio network system. | 02-25-2010 |
20100135330 | METHOD AND SYSTEM FOR SETTING UP HEADER COMPRESSION COMMUNICATION, HEADER COMPRESSION POLICY FUNCTION ENTITY - 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. | 06-03-2010 |
20100198710 | Method, apparatus, and system for implementing prepaid accounting on a network - An embodiment of present invention provides a method for implementing prepaid accounting on a network. The method comprises sending, by a source Anchor data path function (DPF), an Anchor DPF relocation request carrying quota information to a target Anchor DPF; and returning, by the source Anchor DPF, an Anchor DPF relocation acknowledgement message carrying quota compensation information to the target Anchor DPF, when receiving a relocation response sent by the target Anchor DPF. The method for implementing prepaid accounting on a network according to the embodiment of present invention allows the prepaid service to be implemented on the network. | 08-05-2010 |
20100287599 | METHOD, APPARATUS AND SYSTEM FOR IMPLEMENTING POLICY CONTROL - A method, an apparatus and a system for implementing policy control are disclosed. The method includes: an SPDF receives a service request that carries service property of a session from an AF, makes a service policy decision according to the service property of the session and policy pre-configuration parameters to obtain authorized service parameters; and determines a corresponding local network transmission PDF according to a type of an access network; the SPDF sends an access network resource authorization request that carries the authorized service parameters to the determined local network transmission PDF, to enable the local network transmission PDF to generate a local network transmission policy according to the authorized service parameters and deliver the policy to a corresponding policy enforcement point for enforcing. Through the embodiments of the present invention, the converged policy control can be implemented for different types of networks. | 11-11-2010 |
