Description
Technical Field
The present invention relates to a location locking technique for a wireless cellular communication System, and more particularly, to a method and System for re-locking a location of a Home Evolved NodeB (HeNB) or a Home NodeB (HNB) after movement in a security architecture of a Universal Mobile Telephone System (UMTS) network and an Evolved Packet System (EPS) network.
Background
HNBs are used to provide 3G wireless coverage for third generation mobile communications system (3G) handsets located within homes. The HNB is connected to an already existing residential broadband service. The HNB has a standard function of a base station NodeB and a Radio resource management function of a Radio Network Controller (RNC). Wherein the NodeB is an element of the 3G macro radio access network.
Fig. 1 is a schematic system structure of the HNB. In fig. 1, an interface between a User Equipment (UE) and an HNB of a third Generation Partnership Project (3 GPP) is a backhaul and compatible air interface in a Universal Terrestrial Radio Access Network (UTRAN). The HNB accesses the core network of the operator through a security gateway (SeGW). A broadband Internet Protocol (IP) backhaul between the HNB and the SeGW, in which information propagated is to be protected by a secure channel established between the HNB and the SeGW, may be insecure. The SeGW is used for mutual authentication between a core network of an operator and the HNB; a home base station Gateway (HNB GW, HNB Gateway) and a SeGW are logically separated entities in a core network of an operator, and are used for access control of a UE that is not allowed to close a Subscriber Group (CSG); operations and Maintenance Administration (OAM) requires secure communication, especially when the OAM is placed outside the operator's core network.
Fig. 2 is a schematic diagram of a system structure of the HeNB. Fig. 2 is similar to the system architecture of fig. 1, except that the HNB in fig. 1 is replaced by a HeNB, which differs from the HNB in that: the HeNB is an air interface connecting the UE of the 3GPP and an Evolved Universal Terrestrial Radio Access Network (EUTRAN); henbs are typically used for Long Term Evolution (LTE) systems, while HNBs are typically used for 3G systems.
Here, h (e) NB is a generic term of HNB and HeNB, and hereinafter, for the sake of brevity, HNB or HeNB is denoted by h (e) NB.
For security of h (e) NB, 3GPP TR33.820 defines 27 threats. These 27 threats are grouped into 7 broad categories, namely: compromise of h (e) NB credentials, physical attacks on h (e) NB, attacks on the construction of h (e) NB, attacks on the protocols of h (e) NB, attacks on the core network including attacks based on the h (e) NB location, attacks on the data and identity privacy of the user, and attacks on the radio resources and management. Of the 27 threats defined within 3GPP TR33.820, an h (e) NB location based attack is associated with operating the h (e) NB in an out-of-place location. Based on h (e) NB location attack, 3GPP TR33.820 provides a location locking technique to overcome the h (e) NB location attack, and the location locking technique mainly includes two aspects: h (e) location registration of NB; h (e) location authentication of NB.
Specifically, fig. 3 is a prior art h (e) NB location fix solution, defined in 3GPP TR33.820, for overcoming h (e) NB location based attacks. When the location registration of the h (e) NB based on the IP address occurs only at the initial start of the h (e) NB, as shown in fig. 3, the location locking solution of the h (e) NB includes the following steps:
Here, for location registration, after the location registration of h (e) NB based on IP address is completed, the AHR stores the location identifier of h (e) NB as an attribute of h (e) NB, and uses it as a criterion for determining the location of h (e) NB. For location authentication, the location authentication of h (e) NB based on IP address occurs each time h (e) NB requests access to the network, it determines whether the location of h (e) NB has changed by comparing the location identifier stored in the AHR with the location identifier obtained from the CLF based on the IP address of h (e) NB.
However, in practical use, this position locking solution is very imperfect with respect to the breadth and flexibility of h (e) NB applications. Since h (e) NB can be moved, after h (e) NB has moved to a new location for various reasons, if this new location of h (e) NB cannot be relocked, h (e) NB will not be reused, and thus, emergency calls from this h (e) NB will not be reliably located or routed to the correct emergency call center, interception of legitimate location reports will also become impossible a priori. Furthermore, without a mechanism for relocking new locations, this would result in a significant loss of operator revenue when users can use h (e) NB in unauthorized areas, especially abroad. In addition, after the h (e) NB IP address based location is moved, if there is no mechanism for re-locking the new h (e) NB IP address based location, when an h (e) NB is placed in another area, the proxy server can use the same IP address as the h (e) NB to impersonate the properly registered h (e) NB for proxy attack.
In summary, the new requirements are: h (e) the new location of the NB after the movement must also be relocked to overcome the threat of an attack resulting from operating the h (e) NB in an unsuitable location, i.e., a solution for relocking the new location after the h (e) NB movement needs to be provided. Currently, there is no effective solution to this new need.

step 2021a, H (e) NB sends the location information request message to the AHR; the location information request message encapsulates the IP address updated by the h (e) NB.
Step 2021b, AHR parses the IP address updated by h (e) NB from the location information request message, encapsulates the IP address into the location information search request message, and sends the location information search request message to CLF.
Step 2021c, when the CLF parses the IP address updated by h (e) NB from the location information search request message, and searches for the new location information according to the IP address updated by h (e) NB, sends the new location information to the AHR.
After step 2021c is executed, the AHR may acquire new location information corresponding to the IP address updated by h (e) NB from the CLF, determine a new location to which h (e) NB moves according to the new location information, and implement re-registration of h (e) NB; the network side permits the service access of the H (e) NB realizing the re-registration and successfully realizes the re-locking of the H (e) NB to the new position.

In summary, the present invention mainly includes the following contents:
firstly, the method comprises the following steps: when the location of an H (e) NB is about to change, such as H (e) NB is moved from one residence to another by its owner, H (e) NB sends its location information deregistration request message to the AHR based on the current IP address of H (e) NB.
Secondly, the method comprises the following steps: after receiving the logout request message, the AHR logs out the existing location information of h (e) NB based on the current IP address of h (e) NB, replies h (e) NB that the logout was successful, and authorizes the h (e) NB to re-register the corresponding new location based on the IP address updated by the h (e) NB obtained by moving to the new location.
Thirdly, the method comprises the following steps: h (e) after the NB moves and is installed at a new position, the NB sends a position request message to the AHR according to the IP address of the new position, namely the obtained IP address updated by the H (e) NB; the AHR sends a location information search request message to the CLF according to the IP address updated by the H (e) NB of the new location, so as to inquire and search new location information corresponding to the IP address updated by the H (e) NB.
