Embodiment 1

[0070] Embodiment 1, during the initial access process or the handover access process, the indication information is obtained through the authentication process, such as Figure 6 As shown, for the initial access or handover process initiated by the UE, the access authentication process for the UE needs to be performed between the UE and the non-3GPP access gateway and HSS / AAA. The figure shows a simplified access authentication diagram. The specific implementation details of access authentication may 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. This figure aims to In the description of the generation, transfer and function of the indication information during the access authentication process, the method for the non-3GPP access gateway to obtain the indication information during the access authentication process is as follows:

[0071] ...

Embodiment 2

[0081] Embodiment 2: In the access process, the instruction information is obtained from the PMIP binding update confirmation message replied by the visiting service gateway, such as Figure 7 shown, including the following steps:

[0082] Step 1: UE executes the access procedure 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 the process, the non-3GPP access gateway obtains the static QoS value subscribed by the user from the HSS / AAA (this process is for trusted The non-3GPP access is the EAP-AKA process, and the non-trusted non-3GPP access is the IKE process);

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

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

Embodiment 3

[0105] Embodiment 3: In a tightly coupled handover scenario, the non-3GPP access gateway on the new side obtains indication information from the context process passed by the access gateway on the original side, and the method for obtaining the indication information by the access gateway on the original side is implemented in the present invention The example is not limited, and the indication information may be obtained from the HSS / AAA server when the access gateway on the original side establishes an 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 it can be an access gateway under a different access technology) ) for context transfer, so as to obtain some information about the connection establishment of the new side, which contains indication information, which is us...

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 ...
