Problems solved by technology

[0031] In view of this, the main purpose of the present invention is to provide an admission control implementation method and system to solve the problem that the existing admission control implementation technology cannot provide CSG users with services under the situation that the authorized fixed network resources on the HeNB are in short supply. The problem of QoS guarantee

Embodiment 1

[0081] The application scenario of this embodiment is: when the admission control result of the BPCF to the user is rejection, the HeNB performs the second admission control on the user according to the CSG information and the ARP information (that is, the HeNB performs resource preemption according to the CSG information and the ARP information ). Wherein, the user's CSG information is obtained when the UE accesses the HeNB.

[0082] The preconditions for the application of this embodiment are: assuming that user A is a CSG user and user B is a non-CSG user, the resource preemption capability of user A is lower than that of user B, that is, the ARP priority of user A is lower, and the resource preemption capability of user B is lower than that of user B. The priority of user B is higher; user B has started the service, and the network (fixed network and mobile network) has allocated resources for user B to start the service. The HeNB-authorized QoS has been occupied by user ...

Embodiment 2

[0102] When the admission control result of the BPCF to the user is rejection, the HeNB performs the second admission control on the user according to the CSG information and the ARP information (that is, the HeNB performs resource preemption according to the CSG information and the ARP information). Wherein, the user's CSG information is obtained when the UE accesses the HeNB.

[0103] The prerequisite for the application of this embodiment is as follows: assume that user A is a non-CSG user, user B is a CSG user, and the resource preemption capability of user A is lower than that of user B. User B has started the service, and the network (fixed network and mobile network) has allocated resources for user B to start the service. The HeNB-authorized QoS has been occupied by user B to carry out business, so on the premise that user A cannot seize resources, the available HeNB-authorized QoS can no longer meet the QoS requirements of user A to carry out business. At this time, H...

Embodiment 3

[0112] The scenario and preconditions described in this embodiment are the same as those in Embodiment 1, the difference lies in the bearer operation process: in Embodiment 1, before the second admission control, the HeNB to CN side has already carried out the bearer resources according to the authorized QoS issued by PCRF. reserved. However, once the HeNB performs the second admission control and refuses to admit users to carry out services, it needs to re-release the bearer resources reserved from the HeNB to the CN side. In order to reduce the resource allocation and release frequency of the network elements from the HeNB to the CN side, This embodiment provides another admission control processing manner.

[0113] In addition, the first embodiment describes that when the HeNB performs the second admission control according to the CSG information and / or ARP information, it accepts user A to carry out services by releasing all bearer resources of user B; while this embodimen...

Abstract

The present invention discloses a method and system for realizing admission control, comprising: a home base station or a home base station gateway according to closed subscriber group (CSG) information and allocation and maintenance priority (ARP) information of a first user and a second user, or The CSG information controls the admission of the first user's business; through the present invention, it can provide a service quality (QoS) guarantee for the CSG user's business when the use of authorized fixed network resources on the home base station is in short supply.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for realizing admission control. Background technique [0002] The Evolved Packet System (EPS for short) developed by the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) consists of a Mobility Management Entity (MME for short), a Serving Gateway (Serving Gateway for short), S-GW), packet data network gateway (Packet Data Network Gateway, referred to as P-GW), home subscriber server (Home Subscriber Server, referred to as HSS) 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) netw...
