Description

家庭基站系统中获取公网IP地址的方法及系统 Get public IP address of the home base station system method and system

技术领域 FIELD

[0001] 本发明涉及家庭基站系统技术,尤指一种家庭基站系统中获取公网IP地址的方法及系统。 [0001] The present invention relates to a home base station system technology, particularly to a method and system for acquiring a public IP address of a home base station system.

背景技术 Background technique

[0002] 家庭基站是一种小型、低功率的基站,部署在家庭及办公室等室内场所。 [0002] Femtocell base station is a small, low-power, deployed in indoor places such as home and office. 家庭基站的主要作用是给用户提供更高的业务速率,并降低使用高速率服务所需要的费用,同时弥补已有分布式蜂窝无线通信系统覆盖的不足。 The main role of the family base is to provide users with higher service rate and reduce the cost of using high-speed services they need, at the same time to make up for lack of existing distributed cellular wireless communication system coverage. 家庭基站的优点是实惠、便捷、低功率输出、即插即用等。 Advantage of the home base station is affordable, convenient, low power output, plug and play. 在3G系统中称为家庭基站(HNB,Home NodeB),在长期演进(LTE,Long Term)系统中称为家庭演进基站(HeNB,Home eNodeB),可以合并表示为H(e)NB或者HNB/HeNB。 In the system referred to as 3G a home base station (HNB, Home NodeB), referred to as home evolved NodeB (HeNB, Home eNodeB) in long term evolution (LTE, Long Term) system, may be incorporated is expressed as H (e) NB or HNB / HeNB. 下文中,家庭基站指HNB或HeNB。 Hereinafter, the home base station HNB means or HeNB.

[0003] 家庭基站用户是通过家庭基站接入网(H (e) NB AN, Home (e) NodeBAccessNetwork)连接到核心网(CN,Core Network)的,H(e)NB AN由H(e)NB和家庭基站网关(H(e)NB Gff, Home (e)NodeB Gateway)共同组成。 [0003] The user home base station is an access network through the home base station (H (e) NB AN, Home (e) NodeBAccessNetwork) connected to a core network (CN, Core Network) is, H (e) NB AN by the H (e) NB gateway and the home base station (H (e) NB Gff, home (e) NodeB gateway) composed. H(e)NB GW的主要功能为验证H(e)NB的安全性、处理H(e)NB的注册和接入控制、对H(e)NB进行运行维护管理、根据运营商要求配置和控制H(e)NB,以及负责交换核心网和H(e)NB的数据等。 The main function of H (e) NB GW to verify the safety of H (e) NB of, and access control registration processing H (e) NB, and for H (e) NB for operation and maintenance management, and arranged according to operator requirements control H (e) NB, and switched core network and is responsible for H (e) NB of the data and the like. 家庭基站管理系统(H(e)MS)最主要是为H(e)NB实现配置管理功能,比如位置信息的核实、为H(e)NB进行参数配置,主要涉及到CN级别的参数配置、RAN侧的参数配置以及RF的参数配置。 HNB Management System (H (e) MS) is implemented as main H (e) NB configuration management functions such as verification of the location information, parameter configuration to H (e) NB, mainly related to the CN-level configuration parameters, RAN configuration parameters and the RF side of the configuration parameters. 在3G系统中家庭基站管理系统称为HMS,在长期演进LTE系统中称为家庭基站演进管理系统(HeMS),可以合并表示为H(e)MS或者HMS/HeMS。 In the 3G system, is called a home base station management system HMS, referred to as a home base station management system evolved (the HeMS) in an LTE system, may be incorporated is expressed as H (e) MS or HMS / HeMS. 下文中,家庭基站管理系统指HMS或HeMS。 Hereinafter, the home base station refers to the management system or HMS HeMS. 对3G系统,无线接入网和核心网接口继承宏基站和核心网接口为Iu接口JtLTE系统,无线接入网和核心网接口继承宏基站和核心网接口为SI接口。 For 3G systems, wireless access and core network interface inheritance macro base station and core network interface is the Iu interface JtLTE system, radio access network and the core network interface inheritance macro base station and core network interfaces for SI interface. Iu 口或者SI接口的物理连接存在于H(e)NBGW,从逻辑上看,Iu接口应用层协议RANAP (对LTE系统,SI接口应用层协议为S1-AP)可能分布在H (e) NB或者H (e) NB GW上,或者同时分布在H (e) NB和H (e) NB GW两个网元上。 Iu interface or a physical interface connection exists SI H (e) NBGW, logically, the RANAP Iu interface application layer protocol (for the LTE system, SI interface application layer protocol S1-AP) may be distributed in the H (e) NB or the H (e) NB GW, or simultaneously distributed over the H (e) NB and the H (e) NB GW two NEs. 对LTE系统,HeNB可以直接连接到核心网,网络架构和宏基站类似。 Of the LTE system, the HeNB may be directly connected to the core network, network architecture, and the like macro base station.

[0004] 如图1所示,用户可以通过家庭基站直接访问互联网及家庭网络的资源,以实现家庭基站的本地IP接入(LIPA,1calIP access)功能。 [0004] As shown, the user can directly access the Internet and the home network resources to achieve local IP access home base station (LIPA, 1calIP access) via the home base station 1 function. 通过LIPA方式,一方面可以降低对移动核心网的资源占用,并且用户能够更加快速、便捷地使用Internet提供的业务;另一方面,也能满足运营商分流业务的需求。 By LIPA way, one can reduce the footprint of the mobile core network, and the user can more quickly and easily using the Internet to provide services; on the other hand, also to meet the needs of business operators shunt.

[0005] 在UMTS系统,终端正常访问Internet等外部网络时,需要通过服务网关支持节点(SGSN)以及GPRS网关支持节点(GGSN)完成来完成;对于LTE系统,则是通过服务网关(S-GW, Serving gateway)以及分组数据网关(PDNGW,Packet Data Network gateway,也可简称为P-GW)来完成的。 [0005] When a UMTS system, the terminal access the Internet and other external networks needs to be done by a serving gateway support node (SGSN) and Gateway GPRS Support Node (GGSN) is completed; for the LTE system, by a serving gateway (S-GW , Serving gateway) and a packet data gateway (PDNGW, packet data Network gateway, may be simply referred to as P-GW) to complete. SGSN、GGSN以及S_GW、P-Gff均为核心网网元。 SGSN, GGSN and S_GW, P-Gff are core network element.

[0006] 为了实现家庭基站支持LIPA的功能,需要将现有的部分核心网功能模块部署在H(e)NB上。 [0006] In order to realize the function of the home base station supports the LIPA, it requires the core network part of existing function modules deployed on the H (e) NB. 对于HNB系统,需要将GGSN的功能甚至部分的SGSN功能部署在本地HNB上,而对于HeNB系统则需要将I3DN Gff甚至部分的S-GW功能部署在HeNB上。 For HNB system, GGSN functions even SGSN functional portion need to be deployed on a local HNB, HeNB and for the system is required to I3DN Gff S-GW function even partially deployed on HeNB. 作为连接访问接入点名(APN,Access Point Name)的TON GW以及GGSN要在家庭基站实现,需要一个公网地址来进行路由以访问Internet。 The access point name as the connection (APN, Access Point Name) in the GGSN and TON GW to be implemented in the home base station, one public address to route to access the Internet.

[0007] 由于家庭基站的定位为即插即用的设备,其初始IP地址由初始连接的网络供应商提供,但是,由网络运营商提供的IP地址通常是私有地址,而无法保证其是满足LIPA功能所需的可路由的公网地址。 [0007] Due to the positioning of the home base for the Plug and Play device, the initial IP address provided by the network provider's initial connection, however, the IP address provided by the network operator is typically a private address, but can not guarantee it is to meet LIPA desired function routable public address. 如果该IP地址不是可路由的公网地址,那是无法正常实现LIPA 的。 If the IP address is not routable public IP address, that can not be achieved LIPA's normal.

发明内容 SUMMARY

[0008] 有鉴于此,本发明的主要目的在于提供一种家庭基站系统中获取公网IP地址的方法,能够保证H(e)NB获得可路由的公网地址,正常实现LIPA。 [0008] In view of this, the main object of the present invention to provide a method of obtaining a public IP address of the home base station system, to ensure that H (e) NB obtained routable public addresses, to achieve normal LIPA.
