Example Embodiment

[0070] In the first embodiment, the indication information is obtained through the authentication process during the initial access process or the handover access process, such as Figure 6 As shown, for the initial access or handover process initiated by the UE, the UE and the non-3GPP access gateway and HSS / AAA need to perform an access authentication process for the UE. The figure shows a simplified access authentication diagram. The specific access authentication implementation details can be different from this figure. For example, for trusted non-3GPP access, the access authentication process is EAP-AKA process, and for untrusted access authentication, it is IKE process. In explaining the generation and transmission of indication information and its functions in the access authentication process, the method for non-3GPP access gateways to obtain indication information in the access authentication process is as follows:

[0071] Step 1-Step 3: The access authentication reques...

Example Embodiment

[0081] In the second embodiment, in the access procedure, the indication information is obtained from the PMIP binding update confirmation message replies from the service gateway of the visited place, such as Figure 7 As shown, including the following steps:

[0082] Step 1: The UE executes the access process of the non-3GPP access system;

[0083]Step 2: The authentication process between the non-3GPP access gateway and the UE and HSS / AAA. As part of this process, the non-3GPP access gateway obtains the static QoS value of the user subscription from the HSS / AAA (this process is for trusted Non-3GPP access is the EAP-AKA process, and the non-trusted non-3GPP access is the IKE process);

[0084] Step 3: The layer three message is triggered. For trusted non-3GPP access, it can be a DHCP message, etc.; for untrusted non-3GPP access, the message is an IKE request message;

[0085] Step 4: The non-3GPP access gateway sends a PMIP binding update request to the visited service gateway;...

Example Embodiment

[0105] Embodiment 3: In a tightly coupled handover scenario, the non-3GPP access gateway on the new side obtains indication information from the context passed by the access gateway on the original side. The way the access gateway on the original side obtains the indication information is implemented in the present invention The example is not limited, and the indication information can be obtained from the HSS / AAA server when the access gateway on the original side establishes the initial connection for the UE, such as Figure 8 As shown, for tightly coupled handover, the non-3GPP access gateway on the new side can be the same as the access gateway on the original side (it can be an access gateway under the same access technology or an access gateway under a heterogeneous access technology ) Perform context transfer to obtain some information about the connection establishment of the new side. The information contains indication information for the non-3GPP access gateway to dete...

Abstract

The invention relates to a method for obtaining interactive mode with a maneuver decision entity by a non-3GPP access gateway which belongs to the communication field. The method includes steps: the non-3GPP access gateway obtains an indication information; the non-3GPP access gateway confirms whether initiating interactive process with the maneuver decision entity according with the indication information. The invention also provides the non-3GPP access gateway and an indication information distributing device. In an embodiment of the invention, the non-3GPP access gateway obtains indication information for deciding whether initiating the interactive process with the maneuver decision entity to obtain dynamic QoS maneuver information for deciding wireless resource distributing, charging, data transmitting expression. The method can ensure the non-3GPP access gateway obtaining correct QoS information, accordingly, the information can be processes efficiently.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and a device for a non-3GPP access gateway to learn an interaction mode with a policy decision-making entity. Background technique [0002] Such as figure 1 Shown is the architecture diagram of the SAE (System Architecture Evolution, System Architecture Evolution) network in the roaming scenario. In addition to supporting 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project) access technology, the SAE network will support a variety of Non-3GPP wireless access networks, such as Wimax (Worldwide Interoperability for Microwave Access, global interoperability for microwave access), WLAN (Wireless Local Area Network, wireless local area network), etc., the non-3GPP access systems are divided into trusted and untrusted Two types, which are connected through different interfaces to realize mobility management. In addition to ...
