Description

A kind of method and system of re-locking positions

Technical field

The present invention relates to the locking position technology of radio honeycomb communication system, relate in particular to a kind of at global radio telephone system (UMTS, Universal Mobile Telephone System) network and evolved packet system (EPS, Evolved Packet System) evolution base station (HeNB of family in the security architecture of network, Homeevolved NodeB) or Home eNodeB (HNB, Home NodeB) move the method and system of back re-locking positions.

Background technology

HNB is used to 3-G (Generation Three mobile communication system) (3G) mobile phone that is in the family that the wireless coverage of 3G is provided.HNB is connected to the dwelling house broadband service that has existed.HNB possesses the base station node B function of standard and the radio resource management function of radio network controller (RNC, Radio Network Controller).Wherein, NodeB is an element of the grand Radio Access Network of 3G.

Be illustrated in figure 1 as the system configuration schematic diagram of HNB.Among Fig. 1, third generation cooperative enterprise project (3GPP, 3rd Generation Partnership Project) subscriber equipment (UE, User Equipment) and the interface between the HNB, in Universal Terrestrial Radio Access Network (UTRAN, Universal TerrestrialRadio Access Network) is backhaul and compatible air interface.HNB is by the core net of security gateway (SeGW, security gateway) access carrier.Broadband the Internet protocol between HNB and the SeGW (IP, Internet Protocol) backhaul may be unsafe, and the information of propagating in this backhaul will be protected by the escape way of being set up between HNB and the SeGW.Wherein, SeGW is used for the mutual authentication carried out between the core net of operator and the HNB; Femto gateway (HNB GW, HNB Gateway) is the entity that separates in logic in the core net of operator with SeGW, is used for the access control of the UE of non-permission closed user group (CSG, Closed Subscriber Group); Oam (OAM, Operation Administration and Maintenance) needs safe communication, especially when OAM is placed in the core net outside of operator.

Be illustrated in figure 2 as the system configuration schematic diagram of HeNB.The system architecture of Fig. 2 and Fig. 1 is similar, just with the HNB among HeNB replacement Fig. 1, HeNB is with the difference of HNB: HeNB is the air interface that is connected the UE of 3GPP and the universal land radio access web of evolution (EUTRAN, Evolved Universal TerrestrialRadio Access Network); HeNB is generally used for Long Term Evolution (LTE) system, and HNB is generally used for the 3G system.

Here, with the general designation of H (e) NB as HNB and HeNB, below terse in order to describe, represent HNB or HeNB with H (e) NB.

At the safety of H (e) NB, 3GPP TR 33.820 has defined 27 kinds of threats.These 27 kinds of threats are reduced 7 big classes, be respectively: to the harm of H (e) NB credentials, physical attacks to H (e) NB, attack to the structure of H (e) NB, attack to the agreement of H (e) NB, comprise based on the attack of H (e) NB position attack core net, to the attack of user's data and privacy of identities, and to the attack of Radio Resource and management.In 27 kinds of threats of 3GPP TR 33.820 the insides definition, based on the attack of H (e) NB position with relevant at inappropriate position operation H (e) NB.Based on the attack of H (e) NB position, 3GPP TR 33.820 the insides have provided the locking position technology and have overcome attack based on H (e) NB position, and this locking position technology mainly comprises the Location Registration of two aspect content: H (e) NB; The location-authentication of H (e) NB.

Specifically, Fig. 3 is the locking position solution of H in the prior art (e) NB, defines in 3GPP TR33.820, and it is used to overcome the attack based on H (e) NB position.When the Location Registration of IP address-based H (e) NB occurred over just H (e) NB initial start-up, as shown in Figure 3, the locking position solution of H (e) NB may further comprise the steps:

Step 101, H (e) NB transmission comprise the request message of IP address to the local register (AHR, Access point Home Register) of access point.

Step 102, AHR send the relevant location information request message in this IP address to connecting phase position and memory function (CLF, connectivity Session Location and Repository Function).

Step 103, CLF obtain the relevant location mark symbol in this IP address from its database.

Step 104, AHR accord with the position of deciding H (e) NB based on this location mark, and this position of registration H (e) NB.

Step 105, AHR reply response message and give H (e) NB.

Here, at Location Registration, the location mark symbol that AHR can preserve H (e) NB after the Location Registration of IP address-based H (e) NB is finished is used as the attribute of H (e) NB, and with it as the standard of judging H (e) NB position.At location-authentication, when the location-authentication of IP address-based H (e) NB occurred in each H (e) NB request access network, it was by relatively preserving the location mark symbol among the AHR and accord with determining based on the location mark that the IP address of H (e) NB obtains whether the position of H (e) NB changes from CLF.

Yet in the use of reality, at popularity and flexibility that H (e) NB uses, this locking position solution is imperfection very.Because H (e) NB can be moved, therefore, after H (e) NB moves to a reposition for various reasons, if this reposition of H (e) NB can not be locked again, then H (e) NB can not be used again, thereby, can not be determined the position reliably or be sent to correct EC that from the urgent call that this H (e) NB sends intercepting of legal position message also will become in advance impossible.And, there is not the locking mechanism again of reposition, just can use H (e) NB the user in unauthorized area, particularly abroad the time, this will cause a large amount of losses of operator's income.In addition, after the IP address-based position of H (e) NB is moved, if there is not the locking mechanism again of the IP address-based reposition of H (e) NB, when a H (e) NB is placed on the another one zone, acting server just can use the IP address identical with this H (e) NB to pretend to be this H (e) NB of registration rationally, carries out proxy attack.

In sum, new demand is: the reposition after H (e) NB moves also must be locked again, to overcome H (e) NB is operated the attack threat that is caused in improper position, that is to say, need provide H (e) NB to move the solution that the back reposition locks again.At present, at this new demand, still there is not effective solution.

Summary of the invention
