Description

Emergency call processing method and device

The present invention relates to emergency call technology in a wireless cellular communication system, and more particularly to a method and apparatus for processing an emergency call. Background technique

The Home NodeB (HNB, Home NodeB) is used to provide 3G wireless coverage for user equipment of the third generation mobile communication system (3G) in the home. The HNB is connected to an existing residential broadband service that includes the functionality of a standard NodeB (an element of a 3G macro radio access network) and a standard radio resource controller (RNC, Radio Network Controller) radio resource. Management function.

Figure 1 depicts the system architecture of the HNB, where the interface between the User Equipment (UE, User Equipment) of the 3rd Generation Partnership Project (3GPP) and the HNB is in the global terrestrial radio access network (UTRAN, Universal). The Terrestrial Radio Access Network is a backhaul and compatible air interface. The HNB accesses the core network of the operator through a security gateway (SeGW, Security Gateway). The bandwidth Internet Protocol (IP) backhaul between the HNB and the SeGW may be insecure, and the information transmitted during the backhaul. It needs to be protected by a secure channel established between HNB and SeGW. SeGW performs mutual authentication on behalf of the carrier's core network and HNB. The home base station gateway (HNB GW, HNB Gateway) and the SeGW are logically separated entities in the operator's core network, and the HNB GW is used for access control of UEs of the Closed Subscriber Group (CSG). HNB Management System (HMS, HNB Management System) requires secure communication.

FIG. 2 depicts the system structure of an evolved home base station (HeNB, Home evolved NodeB). The system structure difference between HeNB and HNB is that HeNB is a UE and evolution that connects to 3GPP. The air interface of the Global Transit Radio Access Network (EURTAN).

H ( e ) NB includes HNB and HeNB, and is a general term for HNB and HeNB. In H ( e ) NB, the Hosting Party Module ( HPM) is a physical entity completely separate from the physical environment of H ( e ) NB and is used by the wireless network operator (MNO , Mobile Network Operator ). Identification and certification of HP (Hosting Party). HP certification must be based on HPM, which must be an environment that is resistant to tampering and must include a certificate for authenticating HP. HPM must be bundled with HP and provided to HP by MNO. The HPM is provided by the Universal Integrated Circuit Card (UICC). After the mutual authentication of the device is successful, the carrier network selectively performs mutual authentication of the HP. When the HP authentication is used, the device authentication and the HP authentication must be successfully completed before the secure tunnel connecting the carrier network is established.

In the existing specification 33.320, the certification for HP has the following provisions: If the HP certification is selected, when the HPM for mutual authentication with the MNO is removed from the H(e)NB, H

(e) The NB must close its air interface and disconnect from the carrier's core network.

In the security aspect of emergency call processing, the specification 33.320 states: Regardless of whether the UE can pass the access control, the H(e)NB and/or the operator's core network entity (such as H(e)NB gateway) must allow emergency call. This provides a high priority for H ( e ) NB to support the UE's emergency call. H ( e ) NB can work when HPM is removed; according to the specification, H ( e ) NB must close its air interface and Disconnecting from the carrier's core network will definitely result in the interruption of the emergency call, which does not correspond to the high priority support for emergency calls, and cannot meet the requirements.

(e) The communication system is well supported for emergency calls. Summary of the invention

Among them, H(e)NB knows that HPM is removed by detection, or is notified by the carrier network that HPM has been removed; the carrier network knows that HPM has been removed by detection, or H(e)NB tells HPM to be removed. The so-called removal of HPM includes: HPM was removed before the host's HP mutual authentication was successful, or HPM was removed after HP's mutual authentication.

Based on the above idea, the method for processing an emergency call by the H(e)NB provided by the present invention, as shown in FIG. 3, mainly includes the following steps:

Step 302: The H ( e ) NB and/or the carrier network allow the UE to perform emergency after the device authentication succeeds and/or the secure connection between the H ( e ) NB and the carrier network, whether the HPM is removed or not. call. Of course, for this case, the H(e)NB and/or the carrier network also allow other normal services of the UE.

Step 303: H ( e ) NB determines whether the HPM is removed before the mutual authentication of the HP. If yes, step 304 is performed; otherwise, step 305 is performed.

H ( e ) NB can detect whether HPM has been removed by itself; it can also detect whether HPM has been removed by the operator network and inform H ( e ) NB of the test result.

Step 304: After the device authentication success and/or the secure connection between the H(e)NB and the carrier network is established, the H(e)NB and/or the carrier network allow the UE to make an emergency call.

HPM is removed before HP's mutual authentication, and HP's mutual authentication is not performed between H(e)NB and the carrier's network.

Step 305: H ( e ) NB determines whether the mutual authentication of the HP is successful. If yes, step 307 is performed; otherwise, step 306 is performed.

Step 306: When the mutual authentication of the HP fails, to allow the UE to make an emergency call, a secure connection is established between the H(e)NB and the carrier network.

Step 307: When the mutual authentication of the HP is successful, the H(e)NB establishes a secure connection with the carrier network, and the H(e)NB and/or the carrier network allow the UE to make an emergency call. Of course, for this case, the H(e)NB and/or the carrier network also allow other normal services of the UE.
