Problems solved by technology

[0017] The purpose of the present invention is to provide a method for realizing service admission control, so as to overcome that when the above-mentioned users access the EPS network through the HNB / HeNB to carry out services, because the policy control entity does not formulate a control policy according to the user CSG information, it cannot provide CSG users The problem of providing QoS guarantee first in business development

application example 1

[0136] Assume that UE-A and UE-B access the EPS network through the same HNB / HeNB, where user A using UE-A is a CSG user, and user B using UE-B is a non-CSG user. UE-A and UE-B carry out services at the same time, and the network needs to combine the user's CSG information to perform admission control for the services they carry out.

[0137] Before starting the service, the user needs to attach to the EPS network through the HNB / HeNB. During the attachment process, the user needs to share the IPSec tunnel information used by the user (that is, the IPSec tunnel information established between the HNB / HeNB and the Se-GW, including the HNB / HeNB local IP address) and other information (such as user ID, user CSG information, etc.) are sent to PCEF / BBERF. In this embodiment, user A and user B are attached to the EPS network through HNB / HeNB as an example. During the attachment process, user A and user B need to send their respective user IDs, CSG information, and IPSec tunnel infor...

application example 2

[0150] Assuming that UE-A and UE-B access the EPS network through the same HNB / HeNB, user A using UE-A is a CSG user, and user B using UE-B is a non-CSG user. UE-A and UE-B carry out services at the same time, and the network needs to combine the CSG information of user A and user B to perform admission control for the services they carry out.

[0151] During the attachment process, UE-A and UE-B send the corresponding CSG information and user identification information of user A and user B to the BPCF, and the BPCF stores the relevant information.

[0152] BPCF implements the admission control process for users to carry out business, as shown in Figure 6, including:

[0153] 601. UE-A attaches to the EPS network through the HNB / HeNB;

[0154] 602. PCEF / BBERF receives an attach request from UE-A, which includes user A's identification information and IPSec tunnel information, etc.; DRA discovers PCRF-A according to the user identification, and PCEF / BBERF and PCRF-A establish ...

application example 3

[0173] This example is aimed at the process in which a user develops services and implements admission control after attaching to the EPS system through the HNB. according to figure 1 In the architecture shown, if the user accesses the EPS through the HNB, the HNBGW must be deployed. When the HNB is powered on, the HNB GW discovers the PCRF that serves the HNB access HNB And establish S15 session, send IPSec tunnel information to PCRF HNB , PCRF HNB Discover BPCF according to HNB IP address in IPSec tunnel information, and then establish S9* session with BPCF.

[0174] When a user attaches to the EPS network through the HNB, the HNB GW sends the user's CSG information and identification information to the PCRF HNB , PCRF HNB The user's CSG information and identification information are sent to the BPCF through the S9* session for storage.

[0175] The process of BPCF implementing policy control on UE-A and UE-B services is as follows: Figure 7 shown, including:

Abstract

The invention discloses a method and a system for achieving service admission control. The method is used in a broadband policy control function (BPCF). The method comprises the steps of receiving an admission control request for a user development service, which is sent by a policy and charging rules function (PCRF); and conducting admission control for the admission control request according to closed subscriber group (CSG) information of a user. The other achieving method is used in a policy and charging rules function home nodeB subsystem (PCRFHNB) which provides a policy control service for home nodeB subsystem access. The method comprises the steps of receiving an admission control request for a user development service, which is sent by a home nodeB subsystem gateway; and conducting admission control for the admission control request according to the closed subscriber group (CSG) information of the user. By the aid of the methods and the system, a quality of service (QoS) guarantee is preferentially provided for the CSG user service development under the condition that fixed network resources which are authorized to mobile access for use are insufficient.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for realizing service admission control. Background technique [0002] The Evolved Packet System (EPS for short) developed by the 3rd Generation Partnership Project (3GPP for short) consists of a Mobility Management Entity (MME for short), a Serving Gateway (Serving Gateway, S-GW for short), Packet Data Network Gateway (P-GW for short), Home Subscriber Server (HSS for short) and other network elements, such as figure 1 shown. [0003] MME is responsible for mobility management, non-access stratum signaling processing, and user mobility management context management; S-GW forwards data between user access and P-GW, and is responsible for paging waiting The data is cached; the P-GW is the border gateway between the EPS and the Packet Data Network (PDN) network, and is responsible for functions such as accessing the PDN and forwarding data between ...
