Therefore, it is easy to be intercepted by other users to form a security risk.
例如，UE-2通过UE-1的注册请求(Registration Request)获得了UE-1的PSI参数(因为Registration Request是明文发送的)，那么UE-2可以自己发起注册请求并携带UE-1的PSI参数，网络设备会向UE-2下发UE-1的UE Policy，造成安全隐患和隐私泄露。For example, UE-2 obtains the PSI parameter of UE-1 through the registration request of UE-1 (because the Registration Request is sent in plaintext), then UE-2 can initiate the registration request and carry the PSI of UE-1. The network device sends a UE Policy of UE-1 to the UE-2, causing security risks and privacy leaks.

此外，图1所示的终端设备可以根据与用户设备路径选择策略URSP中的第一规则对应的路径选择描述符表，进行协议数据单元PDU会话的建立和/或绑定，该路径选择描述符表包括至少一组索引组合，上述至少一组索引组合中的每组索引组合包括至少一 个索引，该每组索引组合用于指示一组参数组合，该参数组合包括用于建立和/或绑定PDU会话的至少一个参数中每个参数的值，上述至少一个索引与上述至少一个参数一一对应，上述每个参数包括至少一个值。Furthermore, the terminal device shown in FIG. 1 can perform establishment and/or binding of a protocol data unit PDU session according to a path selection descriptor table corresponding to a first rule in the user equipment path selection policy URSP, the path selection descriptor The table includes at least one set of index combinations, each set of index combinations in the at least one set of index combinations including at least one index, the set of index combinations being used to indicate a set of parameter combinations, the set of parameters including for establishing and/or binding And a value of each parameter in at least one parameter of the PDU session, wherein the at least one index is in one-to-one correspondence with the at least one parameter, and each of the parameters includes at least one value.
由此，本发明实施例中引入了URSP，URSP策略是用于选择不同协议数据单元(Protocol Data Unit，PDU)会话(Session)的策略。URSP策略规定了UE对于不同数据流滤波器的路由策略。其中，对于UE来讲，只有一个URSP，且URSP中可以有多种规则，URSP中的规则可以包括但不限于包括数据流描述符(Traffic descriptor)、应用标识(Application identifiers)、网络协议(Internet Protocol，IP)描述符(descriptors)、非IP描述符(non-IP descriptors)以及路径选择描述符(Route Selection descriptor，RSD)等。每个规则还可以有不同的优先级值。其中，该RSD表包括但不限于包括至少一个用于建立和/或绑定协议数据单元(Protocol Data Unit，PDU)会话的参数的值，例如：会话和业务连续性模式、网络切片辅助信息(Network Slice Selection Assistance Information，NSSAI)、数据网络名称(Data Network Name，DNN)、非无缝分流指示以及无线接入类型等。每个参数可以包括至少一个值。本申请实施例中的参数组合可以是指各种参数的值的组合，例如，会话和业务连续性模式1、NSSAI_1、DNN_1、非无缝分流指示为允许以及无线接入类型为第三代合作伙伴项目(3rd Generation Partnership Project，3GPP)为一个参数组合，会话和业务连续性模式1、NSSAI_2、DNN_3、非无缝分流指示为允许以及无线接入类型为第三代合作伙伴项目(3rd Generation Partnership Project，3GPP)为另外一个参数组合。在本申请实施例中，可以先将每个参数的所有值都用索引表示，例如，会话和业务连续性模式有三个值，会话和业务连续性模式1由索引1表示，会话和业务连续性模式2由索引2表示，会话和业务连续性模式3由索引3表示。那么就可以用索引组合指示参数组合。例如索引组合为[2；1；2；1；1]，假设该索引组合中每个索引从左到右的顺序代表的参数分别为：会话和业务连续性模式、NSSAI、DNN、非无缝分流指示以及无线接入类型。那么该索引组合[2；1；2；1；1]代表的参数组合为会话和业务连续性模式2、NSSAI_1、DNN_2、非无缝分流指示为允许以及无线接入类型为3GPP的组合。在本申请实施例中，可以在RSD表中增加至少一个索引组合，终端设备可以根据上述至少一个索引组合指示的参数组合中的参数值进行PDU会话的建立和/或绑定。Therefore, the URSP is introduced in the embodiment of the present invention, and the URSP policy is a policy for selecting different Protocol Data Unit (PDU) sessions. The URSP policy specifies the routing strategy of the UE for different data stream filters. For the UE, there is only one URSP, and there may be multiple rules in the URSP. The rules in the URSP may include, but are not limited to, including a traffic descriptor, an application identifier, and a network protocol. Protocol, IP) descriptors, non-IP descriptors, and Route Selection descriptor (RSD). Each rule can also have different priority values. The RSD table includes, but is not limited to, a value including at least one parameter for establishing and/or binding a Protocol Data Unit (PDU) session, such as a session and a service continuity mode, and network slice assistance information ( Network Slice Selection Assistance Information (NSSAI), Data Network Name (DNN), non-seamless offload indication, and wireless access type. Each parameter can include at least one value. The parameter combination in the embodiment of the present application may refer to a combination of values of various parameters, for example, session and service continuity mode 1, NSSAI_1, DNN_1, non-seamless offload indication as permission, and wireless access type as third generation cooperation. The 3rd Generation Partnership Project (3GPP) is a combination of parameters, session and business continuity mode 1, NSSAI_2, DNN_3, non-seamless offload indication as allowed, and wireless access type as 3rd Generation Partnership Project (3rd Generation Partnership) Project, 3GPP) is another combination of parameters. In the embodiment of the present application, all values of each parameter may be first indexed. For example, the session and business continuity mode have three values, and the session and business continuity mode 1 is represented by index 1, session and business continuity. Mode 2 is represented by index 2, and session and business continuity mode 3 is represented by index 3. Then you can use the index combination to indicate the parameter combination. For example, the index combination is [2;1;2;1;1], assuming that each index in the index combination represents the parameters from left to right: session and business continuity mode, NSSAI, DNN, non-seamless Split indication and wireless access type. Then the parameter combination represented by the index combination [2; 1; 2; 1; 1] is a combination of session and traffic continuity mode 2, NSSAI_1, DNN_2, non-seamless offload indication is allowed, and radio access type is 3GPP. In the embodiment of the present application, at least one index combination may be added to the RSD table, and the terminal device may perform establishment and/or binding of the PDU session according to the parameter value in the parameter combination indicated by the at least one index combination.

如图2所示，由于用户设备(User Equipment，UE)的策略分段标识(Policy Set Identifier，PSI)列表是明文添加在初始注册(Initial registration)消息中传送给策略控制功能(Policy Control Function，PCF)的，即步骤201、步骤203以及步骤216中。因此，很容易被其他用户截获形成安全隐患。As shown in FIG. 2, the Policy Set Identifier (PSI) list of the user equipment (User Equipment, UE) is sent to the Policy Control Function (Policy Control Function) in the Initial Registration message. PCF), that is, step 201, step 203 and step 216. Therefore, it is easy to be intercepted by other users to form a security risk.
例如，UE-2通过UE-1的注册请求(Registration Request)获得了UE-1的PSI参数(因为Registration Request是明文发送的)，那么UE-2可以自己发起注册请求并携带UE-1的PSI参数，网络设备会向UE-2下发UE-1的UE Policy，造成安全隐患和隐私泄露。又例如，假设UE的Policy的内容被篡改或部分丢失，但是UE始终向网络侧汇报的是同样的PSI参数，这样也不会造成网络侧下发新的UE Policy，进而导致用户设备(User Equipment，UE)的策略(Policy)内容被篡改或部分丢失。For example, UE-2 obtains the PSI parameter of UE-1 through the registration request of UE-1 (because the Registration Request is sent in plaintext), then UE-2 can initiate the registration request and carry the PSI of UE-1. The network device sends a UE Policy of UE-1 to the UE-2, causing security risks and privacy leaks. For example, it is assumed that the content of the policy of the UE is falsified or partially lost, but the UE always reports the same PSI parameter to the network side, so that the network side does not issue a new UE Policy, and thus the user equipment (User Equipment) , UE) Policy content has been tampered with or partially lost.
为了解决上述技术问题，本发明实施例中提出了一种无线通信的方法。In order to solve the above technical problem, a method for wireless communication is proposed in the embodiment of the present invention.
图3是本发明实施例的另一无线通信的方法的示意性框图。FIG. 3 is a schematic block diagram of another method of wireless communication according to an embodiment of the present invention.
具体而言，如图3所示，该方法300包括：Specifically, as shown in FIG. 3, the method 300 includes:
310，第一网络设备获取终端设备的策略分段标识PSI参数。310. The first network device acquires a policy segmentation identifier PSI parameter of the terminal device.
320，该第一网络设备确定是否更新该终端设备的策略信息。320. The first network device determines whether to update policy information of the terminal device.
具体而言，该第一网络设备获取终端设备的策略分段标识PSI参数后，确定是否更新该终端设备的策略信息。如果该第一网络设备确定更新该终端设备的策略信息，则对该终端设备的策略信息进行更新。应理解，本发明实施例中的测量信息可以包括但不限于：第一策略、用户设备路径选择策略(UE Route Selection Policy，URSP)策略以及无线局域网选择策略(Wireless Local Area Network Selection Policy，WLANSP)。其中，第一策略可以是用于选择无线局域网(Wireless LAN，WLAN)接入的服务集标识(Service Set Identifier，SSID)的策略，URSP策略是用于选择不同协议数据单元(Protocol Data Unit，PDU)会话(Session)的策略。本发明实施例中，引入了策略部分标识(Policy Set Identifier，PSI)列表，用于灵活的划分UE Policy。其中，对于PSI参数的使用，可以理解为终端设备是在初始注册(Initial registration)的请求消息中，将该终端设备保存的PSI参数加入进来传送给PCF，这样PCF可以知道当前终端设备存储的PSI参数是什么，以便PCF按需进行UE Policy的调整。Specifically, after acquiring the policy segmentation identifier PSI parameter of the terminal device, the first network device determines whether to update the policy information of the terminal device. If the first network device determines to update the policy information of the terminal device, the policy information of the terminal device is updated. It should be understood that the measurement information in the embodiment of the present invention may include, but is not limited to, a first policy, a UE Route Selection Policy (URSP) policy, and a Wireless Local Area Network Selection Policy (WLANSP). . The first policy may be a policy for selecting a Service Set Identifier (SSID) for wireless LAN (WLAN) access, and the URSP policy is for selecting a different protocol data unit (Protocol Data Unit, PDU). ) The strategy of the session. In the embodiment of the present invention, a Policy Part Identifier (PSI) list is introduced, which is used to flexibly divide the UE Policy. For the use of the PSI parameter, it can be understood that the terminal device is in the initial registration request message, and the PSI parameter saved by the terminal device is added and transmitted to the PCF, so that the PCF can know the PSI stored by the current terminal device. What is the parameter so that the PCF can adjust the UE Policy as needed.
下面对本发明实施例的该第一网络设备确定是否更新该终端设备的策略信息的实现方式进行说明：The following describes the implementation manner of determining whether to update the policy information of the terminal device by the first network device in the embodiment of the present invention:
在一个实施例中，该PSI参数包括用户标识。这种情况下，该第一网络设备接收第二网络设备发送的用户标识；该第一网络设备根据该PSI参数对应的用户标识和该第二 网络设备发送的用户标识，确定是否更新该终端设备的策略。在一个具体实施例中，该第一网络设备确定该PSI参数对应的用户标识和该第二网络设备发送的用户标识不同时，确定更新该终端设备的策略信息。具体地，该第一网络设备确定该PSI参数对应的用户标识和该第二网络设备发送的用户标识不同时，该第一网络设备向该终端设备发送当前使用该终端设备的用户标识对应的策略信息。更具体地，该第一网络设备确定该PSI参数对应的用户标识和该第二网络设备发送的用户标识不同时，该第一网络设备向该终端设备发送该第二网络设备发送的用户标识对应的策略信息。In one embodiment, the PSI parameters include a user identification. In this case, the first network device receives the user identifier sent by the second network device, and the first network device determines whether to update the terminal device according to the user identifier corresponding to the PSI parameter and the user identifier sent by the second network device. Strategy. In a specific embodiment, when the first network device determines that the user identifier corresponding to the PSI parameter is different from the user identifier sent by the second network device, determining that the policy information of the terminal device is updated. Specifically, when the first network device determines that the user identifier corresponding to the PSI parameter is different from the user identifier sent by the second network device, the first network device sends a policy corresponding to the user identifier currently using the terminal device to the terminal device. information. More specifically, when the first network device determines that the user identifier corresponding to the PSI parameter is different from the user identifier sent by the second network device, the first network device sends the user identifier corresponding to the second network device to the terminal device. Strategy information.
其中，该用户标识包括用户永久标识符(Subscriber Private Identifier，SUPI)和/或用户隐蔽标识符(Subscriber Concealed Identifier，SUCI)。在其他可替代的实施例中，该用户标识还可以是由服务提供商(service provider，SP)给UE分配的国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)，IMSI是区别移动用户的标志，储存在用户身份识别卡(Subscriber Identification Module，SIM)卡中，可用于区别移动用户的有效信息，该用户标识还可以是临时UE识别号(S-TMSI)或者移动设备国际身份码(International Mobile Equipment Identity，IMEI)等等。The user identifier includes a Subscriber Private Identifier (SUPI) and/or a Subscriber Concealed Identifier (SUCI). In other alternative embodiments, the user identifier may also be an International Mobile Subscriber Identification Number (IMSI) assigned by the service provider (SP) to the UE. The IMSI is different from the mobile user. The identifier is stored in a Subscriber Identification Module (SIM) card and can be used to distinguish the valid information of the mobile user. The user identifier can also be a temporary UE identification number (S-TMSI) or a mobile device international identity code (International). Mobile Equipment Identity, IMEI) and more.
本发明实施例中，PSI参数中通过用户标识(例如，SUPI和/或SUCI)来唯一标识PSI参数的全球唯一性，能够使得网络设备及时/正确更新终端设备的策略信息。此外，采用这种方案，PSI参数本身用于标识签约用户下的一部分用于终端设备的策略信息，其比特(Bit)数比较小，只需要区分出一个签约用户下的不同PSI参数即可(数以十计)。最后，采用这种方案，该第一网络设备通过终端设备的PSI参数中携带的用户标识和从第二网络设备获取的用户标识对比，能够及时/正确的判断该终端设备是否需要更新策略信息。In the embodiment of the present invention, the global uniqueness of the PSI parameter is uniquely identified by the user identifier (for example, SUPI and/or SUCI) in the PSI parameter, so that the network device can timely/correctly update the policy information of the terminal device. In addition, with this scheme, the PSI parameter itself is used to identify a part of the policy information for the terminal device under the subscription user, and the number of bits is relatively small, and only needs to distinguish different PSI parameters under one subscription user ( Count to ten). Finally, with the solution, the first network device can determine whether the terminal device needs to update the policy information in time/correctly by comparing the user identifier carried in the PSI parameter of the terminal device with the user identifier obtained from the second network device.
应当理解，本发明实施例中涉及的该第一网络设备可以为PCF，也可以为核心网络设备，该第二网络设备可以为AMF，也可以为核心网络设备，本发明实施例不做具体限定。It should be understood that the first network device involved in the embodiment of the present invention may be a PCF, or may be a core network device, and the second network device may be an AMF or a core network device, which is not specifically limited in this embodiment of the present invention. .
本发明实施例中，以该PSI参数包括用户标识为例，本发明实施例不限于此，例如，在其他实施例中，该PSI参数包括公共陆地移动网络(Public Land Mobile Network，PLMN)标识和第一标识，该第一标识用于唯一标识该PLMN下的PSI参数。这种情况下，在一个可实现的实施例中，该PSI参数还可以包含时间戳和/或版本标识。由此，该第一网络设备可以根据该PSI参数中的时间戳和/或版本标识，得知该终端设备的策略信息的上一次更新时间，并根据更新时间阈值和/或最新的版本确定是否更新该终端设备的策略信息。例如***的PLMN为46000，***的PLMN为46001。In the embodiment of the present invention, the PSI parameter includes a user identifier as an example, and the embodiment of the present invention is not limited thereto. For example, in other embodiments, the PSI parameter includes a Public Land Mobile Network (PLMN) identifier and a first identifier, the first identifier being used to uniquely identify a PSI parameter under the PLMN. In this case, in an implementable embodiment, the PSI parameter may also include a timestamp and/or a version identifier. Therefore, the first network device can learn the last update time of the policy information of the terminal device according to the timestamp and/or the version identifier in the PSI parameter, and determine whether the update time threshold and/or the latest version is used according to the update time threshold and/or the latest version. Update the policy information of the terminal device. For example, China Mobile's PLMN is 46,000, and China Unicom's PLMN is 46001.
本发明实施例中，通过PLMN标识和第一标识来唯一标识PSI参数，这种情况下，该第一标识的bit数会非常大(数以亿计)，且一个SUPI下面可以携带多个PSI参数，对于网络侧的影响较大。但是，针对用户来说，安全性更高。此外，本发明实施例中，通过该PSI参数中的时间戳和/或版本标识，得知该终端设备的策略信息的上一次更新时间，进而根据更新时间阈值和/或最新的版本确定是否更新该终端设备的策略信息，能够及时/正确的判断该终端设备是否需要更新策略信息。In the embodiment of the present invention, the PSI parameter is uniquely identified by the PLMN identifier and the first identifier. In this case, the number of bits of the first identifier may be very large (in the hundreds of millions), and multiple SUSIs may be carried under one SUPI. Parameters have a greater impact on the network side. However, for users, security is higher. In addition, in the embodiment of the present invention, the last update time of the policy information of the terminal device is obtained by using the timestamp and/or the version identifier in the PSI parameter, and then whether to update according to the update time threshold and/or the latest version. The policy information of the terminal device can timely/correctly determine whether the terminal device needs to update the policy information.
进一步地，本发明实施例中还提供了一种更新该终端设备的策略信息的方式。具体地，该第一网络设备确定更新该终端设备的策略时，更新该终端设备的策略信息。在一个实施例中，该第一网络设备可以周期性更新该终端设备的策略信息。在另一个实施例中，该第一网络设备还可以非周期性更新该终端设备的策略信息。再进一步地，该第一网络设备确定更新该终端设备的策略时，本发明实施例中还提供了一种更新策略信息的实现方式。例如，该第一网络设备确定更新该终端设备的策略时，该第一网络设备可以向该终端设备发送全部策略信息，以便该终端设备根据自身能力在该全部策略信息中选择部分策略信息使用。但是，由于终端设备的能力不同，不同的终端支持的能力不一样，所需要的策略信息也会不同。目前不区分终端设备能力而把该用户定制的所有规则全都 下发给该终端设备，会造成过重的信令负荷以及额外的终端负担。本发明实施例中，该第一网络设备可以根据该终端设备的能力信息，向该终端设备下发/更新部分的策略信息。其中，能力信息包括以下信息中的至少一项：永久设备标识(Permanent Equipment Id，PEI)、该终端设备的语音支持能力、该终端设备的射频选择优先级(Radio Frequency Selection Priority，RFSP)参数、该终端设备上报的单-网络切片选择辅助信息(Single-Network Slice Selection Assistance Information，S-NSSAI)。进一步地，该第一网络设备根据该终端设备的能力信息，更新该终端设备的策略信息之前，该第一网络设备获取该终端设备的能力信息。Further, the embodiment of the present invention further provides a manner of updating policy information of the terminal device. Specifically, when the first network device determines a policy for updating the terminal device, the policy information of the terminal device is updated. In an embodiment, the first network device may periodically update policy information of the terminal device. In another embodiment, the first network device may also update the policy information of the terminal device non-periodically. Further, when the first network device determines the policy for updating the terminal device, the embodiment of the present invention further provides an implementation manner for updating the policy information. For example, when the first network device determines a policy for updating the terminal device, the first network device may send all the policy information to the terminal device, so that the terminal device selects part of the policy information to use in the entire policy information according to its own capability. However, due to the different capabilities of the terminal devices, the capabilities supported by different terminals are different, and the required policy information will be different. At present, all the rules customized by the user are not sent to the terminal device without distinguishing the capabilities of the terminal device, which may cause excessive signaling load and additional terminal load. In the embodiment of the present invention, the first network device may send/update part of the policy information to the terminal device according to the capability information of the terminal device. The capability information includes at least one of the following information: a permanent device identifier (PEI), a voice support capability of the terminal device, and a radio frequency selection priority (RFSP) parameter of the terminal device. Single-Network Slice Selection Assistance Information (S-NSSAI) reported by the terminal device. Further, before the first network device updates the policy information of the terminal device according to the capability information of the terminal device, the first network device acquires the capability information of the terminal device.
此外，本发明实施例中还提供了一种无线通信的方法，包括：In addition, a method for wireless communication is provided in the embodiment of the present invention, including:
