Problems solved by technology

[0013] However, in related technologies, when different user equipments sharing the same subscribed fixed network line access through one or more home base stations, the network side may select different PCRFs for each user equipment, thus, in related technologies, It is impossible to control the total service access QoS requirements of user equipment sharing the same contracted fixed network line but choosing different PCRFs not to exceed the contracted QoS guarantee of the contracted fixed network line

Embodiment 1

[0063] Figure 14 It is a flow chart according to Embodiment 1 of the present invention, Figure 14 shows based on Figure 8 and Figure 11 In the non-roaming architecture, when the UE establishes an IP-CAN session, PCRF and I-PCRF, and I-PCRF and BPCF respectively establish sessions and perform the process of QoS authorization. Among them, the IP-CAN session established by the UE does not have BBERF, including the following steps:

[0064] Step S1401: During the process of the UE requesting to establish an IP-CAN session, the PCEF receives a request to establish an IP-CAN session message, and the request to establish an IP-CAN session message carries the user ID of the user and the PDN ID of the PDN network that requests access , broadband connection information and optional CSG information, etc. Wherein, the broadband connection information may be the public IP address of the residential gateway (Residential GateWay, RGW for short) connected to the HeNB, or the line iden...

Embodiment 2

[0082] Figure 15 It is a flow chart according to Embodiment 2 of the present invention, Figure 15 shows based on Figure 8 In the non-roaming architecture, when the UE establishes an IP-CAN (IP-Connectivity Access Network, IP connection access network) session, PCRF and I-PCRF, and I-PCRF and BPCF establish sessions respectively, and perform QoS authorization process. Among them, the IP-CAN session established by the UE has BBERF, including the following steps:

[0083] Step S1501: In the process of the UE requesting to establish an IP-CAN session, BBERF receives a request to establish an IP-CAN session message, and the request to establish an IP-CAN session message carries the user ID of the user and the PDN ID of the PDN network that requests access , broadband connection information and optional CSG information, etc. The broadband connection information can be the public IP address of the RGW connected to the HeNB, or the line identifier of the RGW, or the username sig...

Embodiment 3

[0104] Figure 16 It is a flow chart according to Embodiment 3 of the present invention, Figure 16 shows based on Figure 9 , Figure 12 Home routing roaming architecture, when the UE establishes an IP-CAN session, H-PCRF and I-PCRF, and I-PCRF and BPCF establish sessions respectively, and perform the process of QoS authorization. Wherein, there is no BBERF in the IP-CAN session established by the UE. Figure 16 specific steps and Figure 14 The steps are similar. The main difference is: the PCEF is located in the home network, and the message received by the PCEF to request the establishment of an IP-CAN session carries the ID of the visited network where the UE is currently roaming, and the PCEF will send the ID to the H-PCRF, so that the H-PCRF will The interworking session establishment message is sent to the visited network, and the visited network selects the I-PCRF according to configuration information and broadband connection information.

Abstract

The invention discloses an authorization request method, an authorization request system and an authorization request device. The method comprises the following steps that: user equipment establishes an Internet protocol connectivity access network (IP-CAN) session by a home evolved NodeB, wherein the home evolved NodeB is connected to a third generation partnership project (3GPP) core network by a subscribed fixed network line; a policy and charging rules function (PCRF) selects an interwork-PCRF (I-PCRF) for the IP-CAN session, wherein the PCRF selects the same I-PCRF for the IP-CAN session established by the subscribed fixed network line; and the PCRF makes a request for performing quality of service (QoS) authorization on the IP-CAN session to the I-PCRF. By the method, the system and the device, QoS control can be performed on all the user equipment (UE) accessing the network by the home evolved NodeB, so that total demands on QoS may not exceed the QoS which can be provided by the subscribed fixed network line accessed by the home evolved NodeB.

Description

technical field [0001] The present invention relates to the communication field, in particular to an authorization request method, system and device. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) consists of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial RadioAccess Network, E- UTRAN), Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW for short), Home User Server (Home Subscriber Server, referred to as HSS), figure 1 It is a schematic diagram of the architecture of HeNB accessing EPS in a non-roaming scenario according to related technologies, figure 2 It is a schematic diagram of the architecture of HeNB accessing EPS in the home route roaming scenario according to the related technology, image 3 It is a schematic diagram of an architecture of HeNB accessing EP...
