Description

UE authentication method and device and method and device for UE authentication

Technical field

This document relates to, but is not limited to, the field of mobile communications, and more particularly to a user equipment (UE) authentication method and apparatus, and a method and apparatus for UE authentication.

Background technique

The trunking communication system is developed to meet the needs of industry users' command and dispatch, and it is a dedicated wireless communication system for specific industry applications. The main feature of the trunking communication system different from the public radio mobile communication system is that, in addition to providing the two-way calling function of the mobile phone, it can also provide group (group) calls, full calls, and even establish call priority levels in the system, and can perform Priority call, emergency call, etc., which are not available in general mobile phones; special functions such as dynamic reorganization and virtual private network in the system are also provided. These features are especially suitable for police, national security department-specific communications, and command and dispatch needs for airports, customs, public transportation, disaster relief, etc. Therefore, the trunking communication system is in government departments, public safety, emergency telecommunications, electric power, civil aviation, petrochemical, military and It has a wide range of applications in enterprises and other fields. It is a versatile and high-performance wireless communication system, and has formed a dedicated communication network independent of the public mobile communication network around the world.

With the increasing shortage of spectrum resources, the voice of the public network cluster has become more and more high. Public network cluster refers to the development of specific trunking communication services based on the existing public mobile communication network.

In order to ensure the ability of cluster user equipment to have continuous calls in critical business situations, 3GPP has proposed the need for IOPS (Isolated E-UTRAN Operation for Public Safety) mode. The so-called IOPS mode means that the (N)eNB (or a group of (N)eNBs) can still provide a certain level of communication capability for the cluster users in the event that the loop is interrupted or the loop fails and the signaling and data cannot be transmitted normally. The NeNB (Nomadic eNB) is a free evolved Node B.

The IOPS network is designed to serve PS UEs (Public Safety UEs). For ordinary users, IOPS is not allowed to access. For an IOPS network with a completely broken loop, The UE under the network coverage can only apply the IOPS to the MCPTT (Mission Critical Push-To-Talk) according to 22.346. Each MCPTT has its dispatching station, if the dispatching station and its underneath All PS UEs are not covered by the IOPS network, and even if access is entered, there is no way to start MCPTT, so the PS UE also needs authentication. However, the related technology does not have an authentication mechanism for the IOPS network.

Set in the system broadcast information.

The method of the above embodiment is further explained by two application examples.

Application example one

Assume that the IOPS-based PLMN ID is a dedicated PLMN ID, as shown in Figure 5, common UE and PS. The UE is under the same IOPS coverage. As shown in Figure 6, the following steps are included:

S1. The UE reads the system broadcast information of the cell, and reads the PLMN ID information in the system information block type SIB1.

S2, for a normal UE, determine whether the identified PLMN ID is the PLMN ID of the IOPS, if yes, execute S3, if it is a non-IOPS PLMN ID, then execute S4;

S3, triggering to terminate reading system broadcast information of the cell, and the process ends;

S4. Continue to read the system broadcast information of the cell, and the process ends.

The UE receives the system broadcast from the eNB or the NeNB. As shown in FIG. 7, the UE first reads the MIB (Master Information Block), then reads the SIB1 (System Information Block Type 1), and reads the PLMN ID from the SIB1. After determining that the PLMN ID is a non-IOPS PLMN ID, the remaining system information is read.

In order to facilitate the UE to identify whether the read PLMN ID is an IOPS PLMN ID, a special design of the IOPS-based PLMN ID is required. For example, the PLMN ID=MCC+MNC, where the MCC is the country number cannot be modified, the MNC is the mobile network number, and is composed of two digits. The domestic PLMN ID and the operator correspond to Table 1.

Table 1 PLMN ID and carrier correspondence table

MCCMCC	MNCMNC	运营商Operator
460460	0000	中国移动China Mobile
460460	0101	中国联通China Unicom
460460	0202	中国移动China Mobile

460460	0707	中国移动China Mobile
460460	2020	中国铁通China Railcom
460460	0505	中国电信China Telecom

At design time, the MNC can be designed as an unused number, such as 80, for generations. The table is based on the IOPS PLMN ID. When the user reads the PLMN ID, it can be easily identified whether it is an IOPS network.

In other optional examples, a specific identifier may be preset in the system broadcast information, and the UE determines, according to the identifier, whether the current cell is a private network.

Application example two

For the PS UE, first determine whether the current network is an IOPS network, and then determine whether its scheduling station or group is in the network where the read cell is located. If the current network is an IOPS network, and the dispatcher group is in the current network, then Access to the network. As shown in Figure 8, the following steps are included:

S1, the PS UE reads the system broadcast information of the cell, and reads the PLMN ID information in the SIB1;

S2, determining whether the identified PLMN ID is the PLMN ID of the IOPS, if yes, executing S3, if it is a non-IOPS PLMN ID, executing S6;

See Appendix 1 for the PLMN ID of the IOPS.

S3, continue to read the system broadcast information of the cell, and read the Director ID (Supervisor ID) in SIB1;

In this example, the console information or the group information is collectively referred to as a Director ID and written in SIB1. The location of the Director ID in the SIB1 should be such that the UE first reads the PLMN ID and performs the step S2. For example, after the field in which the PLMN ID is recorded in the SIB1, the UE needs to determine the PLMN ID first, and then determine whether the information such as the Director ID matches. In other optional examples, since the PLMN ID is located in SIB1, the Director ID may also be placed in the system message after the PLMN ID identifier, such as in SIB2, that is, in the system message of SIB1.

S4, the PS UE compares the read director ID with the pre-existing station side scheduling station information and/or group information, if the two match, then execute S5, if not, execute S6;

The PS UE should be able to know whether the information it reads is the dispatcher information or the group information, and compare it with the corresponding information stored in advance by itself. The PS UE reads the dispatcher information for comparison according to the network or group situation, or reads the group information for comparison, or reads the dispatcher information and the group information for comparison.

S5, continue to read system information, complete the subsequent communication process, and the process ends;

S6: The PS UE terminates reading the system broadcast information of the cell, avoiding unnecessary access procedures, and the process ends.

The PS UE receives the system broadcast from the eNB or the NeNB. As shown in FIG. 9, the UE reads the MIB first, then reads the SIB1, reads the PLMN ID from the SIB1, determines that the PLMN ID is the IOPS PLMN ID, and continues to read the dispatcher information. Or group information, when it is judged that the dispatcher information or the group information matches the local information, the remaining system information is read.

Application example three

When the dispatching station registers in the IOPS network, or after a group registers with the IOPS network, the core network may send its dispatcher information or group information to each (N) eNBs, and the (N)eNB broadcasts The way to broadcast it. The following description will be respectively made.

For the dispatching station:

MCPTT has a dedicated dispatching station. When the dispatching station accesses an IOPS network, the network obtains its dispatching station information, such as registration to its local core network. The core network sets a special identifier for the dispatching station, and this The process is sent to each (N)eNBs in the IOPS network, and the process of the core network transmitting the registered dispatcher information to the (N)eNB is as shown in FIG. 10, and the MME (Mobility Management Entity) or SGW ( Serving GateWay, the serving gateway) transmits Dispatcher Information to the (N) eNB; (N) the eNB returns a Dispatcher Information Accept to the MME or the SGW.

(N) The eNB broadcasts the scheduler information through the cell broadcast. After reading the information, the PS UE matches the pre-stored dispatcher information. If it matches, it continues to read the system information to complete the cell selection process. If not, the communication process is terminated. The dispatch station information can be, for example, a dispatch station identification.

For groups:

On the local core network side, the account opening information of each group is stored. After a group is established, for example, after the group 1 is established, the core network sends the group number to each (N) eNBs in the IOPS network. The flow of the core network transmitting the group information to the (N) eNB is as shown in FIG. 11. The MME or the SGW sends group information to the (N) eNB; (N) the eNB returns a group information reception response to the MME or the SGW. (Group Information accept).

(N) The eNB broadcasts the group information through the cell broadcast. After reading the information, the PS UE matches the pre-stored group information, and if it matches, continues to read the system broadcast message to complete the cell selection process, and if not, terminates the communication process. The group information may be, for example, a group logo.

In addition to being used for IOPS network authentication, the embodiments of the present invention can also be used for network authentication of other dedicated communication systems.
