在一些实施例中，请参见图1b，示出了一种无短消息业务功能设备(SMSF，Short Message Service Function)的增强型互连协议多媒体子系统(IMS，IP Multimedia Subsystem)短消息服务(SMS，Short Message Service)服务架构。请参见图1c，示出了一种使用SMSF的增强型IMS SMS服务架构。在利用上述架构实现IMS SMS服务的场景中，终端需要在注册和使用IMS SMS服务之前注册到核心网并建立分组数据单元(PDU，Packet Data Unit)会话，这会导致不必要地消耗一些网络资源，例如，PDU会话资源。因此，如何降低IMS短信服务的网络资源消耗是需要考虑的问题。In some embodiments, please refer to FIG. 1b, which shows an enhanced interconnect protocol multimedia subsystem (IMS) short message service (SMS) service architecture without a short message service function device (SMSF). Please refer to FIG. 1c, which shows an enhanced IMS SMS service architecture using SMSF. In the scenario where the IMS SMS service is implemented using the above architecture, the terminal needs to register with the core network and establish a packet data unit (PDU) session before registering and using the IMS SMS service, which will result in unnecessary consumption of some network resources, such as PDU session resources. Therefore, how to reduce the network resource consumption of the IMS SMS service is an issue that needs to be considered.

图2a是根据本公开实施例示出的一种通信方法的交互示意图。如图2a所示，本公开实施例涉及通信方法，用于通信系统100(示例性地，应用于图1b示出的服务架构对应的系统)，方法包括：FIG2a is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100 (exemplarily, applied to a system corresponding to the service architecture shown in FIG1b), and the method includes:

步骤S2101：终端向第一通信节点发送消息。Step S2101: The terminal sends a message to the first communication node.

在一些实施例中，第一通信节点接收终端发送的消息。In some embodiments, the first communication node receives a message sent by the terminal.

在一些实施例中，第一通信节点为接入与移动性管理功能(AMF，Access and Mobility Management Function)。In some embodiments, the first communication node is an access and mobility management function (AMF, Access and Mobility Management Function).

在一些实施例中，终端向第一通信节点发送IMS SMS短消息。如此，所述IMS SMS短消息可以通过第一通信节点转发至目标通信节点(例如，第二通信节点)。In some embodiments, the terminal sends an IMS SMS short message to the first communication node. In this way, the IMS SMS short message can be forwarded to a target communication node (e.g., a second communication node) through the first communication node.

在一些实施例中，终端可以基于初始会话协议(SIP，Session initialization Protocol)向第一通信节点发送IMS SMS短消息。In some embodiments, the terminal can send an IMS SMS short message to the first communication node based on the Session initialization Protocol (SIP).

在一些实施例中，所述IMS SMS短消息携带短信提交信息(SMS-SUBMIT)和/或服务中心(SC，Service Center)地址。In some embodiments, the IMS SMS short message carries SMS submission information (SMS-SUBMIT) and/or a service center (SC, Service Center) address.

在一些实施例中，TMS SMS短消息包含在上行链路(UL，UpLink)非接入层(NAS，Non-Access Stratum)传输消息的容器中。如此，可以通过已有的UL NAS传输消息的容器传输TMS SMS短消息，提升了传输资源的利用率。In some embodiments, the TMS SMS short message is included in the container of the uplink (UL) non-access stratum (NAS) transmission message. In this way, the TMS SMS short message can be transmitted through the existing UL NAS transmission message container, thereby improving the utilization rate of transmission resources.

在一些实施例中，TMS SMS短消息会被第一通信节点转发至第二通信节点。In some embodiments, the TMS SMS short message will be forwarded by the first communication node to the second communication node.

在一些实施例中，终端在接收到提交报告后，会向第一通信节点发送第二响应消息，所述第二响应消息指示所述终端是否接收到所述提交报告。如此，第一通信节点在接收到第二响应消息后，可以获知终端是否接收到提交报告。In some embodiments, after receiving the submission report, the terminal sends a second response message to the first communication node, wherein the second The response message indicates whether the terminal has received the submission report. In this way, after receiving the second response message, the first communication node can know whether the terminal has received the submission report.

在一些实施例中，第一通信节点接收所述终端发送的NAS注册请求消息。In some embodiments, the first communication node receives a NAS registration request message sent by the terminal.

在一些实施例中，所述NAS注册请求消息指示所述终端支持基于NAS的IMS SMS。如此，在接收到NAS注册请求消息后，第一通信节点可以基于所述NAS注册请求消息确定所述终端支持基于NAS的IMS SMS，从而可以执行基于NAS的IMS SMS的传输。In some embodiments, the NAS registration request message indicates that the terminal supports NAS-based IMS SMS. Thus, after receiving the NAS registration request message, the first communication node can determine that the terminal supports NAS-based IMS SMS based on the NAS registration request message, thereby performing the transmission of NAS-based IMS SMS.

步骤S2102：第一通信节点和第二通信节点通过第一接口传输数据。Step S2102: The first communication node and the second communication node transmit data through the first interface.

在一些实施例中，第一通信节点通过第一接口传输所述第一通信节点和第二通信节点之间的数据。如此，由于可以通过第一接口直接传输第一通信节点和第二通信节点之间数据，相较于需要建立PDU会话后才能在第一通信节点和第二通信节点之间传输数据的方式，可以节省PDU会话资源。In some embodiments, the first communication node transmits data between the first communication node and the second communication node through the first interface. In this way, since the data between the first communication node and the second communication node can be directly transmitted through the first interface, compared with the method in which the data can be transmitted between the first communication node and the second communication node only after the PDU session is established, PDU session resources can be saved.

在一些实施例中，第一通信节点通过第一接口向第二通信节点发送数据。In some embodiments, the first communication node sends data to the second communication node through the first interface.

在一些实施例中，第一通信节点通过第一接口接收第二通信节点发送的数据。In some embodiments, the first communication node receives data sent by the second communication node through the first interface.

在一些实施例中，第二通信节点为代理呼叫会话控制功能(P-CSCF，Proxy Call Session Control Function)。In some embodiments, the second communication node is a proxy call session control function (P-CSCF, Proxy Call Session Control Function).

在一些实施例中，第一接口为在第一通信节点和第二通信节点之间建立的数据传输接口。In some embodiments, the first interface is a data transmission interface established between the first communication node and the second communication node.

在一些实施例中，第一接口用于传输互联网协议多媒体子系统(IMS，IP Multimedia Subsystem)短消息业务(SMS，Short Message Service)服务的数据。如此，由于可以通过第一接口直接传输第一通信节点和第二通信节点之间的IMS SMS服务的数据，相较于需要建立PDU会话后才能在第一通信节点和第二通信节点之间传输IMS SMS服务的数据的方式，可以节省PDU会话资源。In some embodiments, the first interface is used to transmit data of an Internet Protocol Multimedia Subsystem (IMS) Short Message Service (SMS). In this way, since the data of the IMS SMS service between the first communication node and the second communication node can be directly transmitted through the first interface, compared with the method in which the data of the IMS SMS service can be transmitted between the first communication node and the second communication node only after a PDU session is established, PDU session resources can be saved.

As shown in Figure 6b, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100, and the method includes one of the following steps:

步骤S6201：UE基于AMF的成功认证和授权，在5GC中发起并完成注册过程。UE向AMF发送包括其偏好“IMS SMS over NAS”的注册请求(对应本公开中的发送NAS注册请求消息)，并且如果网络支持“IMS SMS over NAS”，则AMF在注册接受中向UE响应网络能力“IMS SMS over NAS”(对应本公开中的发送NAS注册接受消息)。Step S6201: The UE initiates and completes the registration process in the 5GC based on the successful authentication and authorization of the AMF. The UE sends a registration request including its preference "IMS SMS over NAS" to the AMF (corresponding to the Send NAS Registration Request message in this disclosure), and if the network supports "IMS SMS over NAS", the AMF responds to the UE with the network capability "IMS SMS over NAS" in the Registration Accept (corresponding to the Send NAS Registration Accept message in this disclosure).

步骤S6202：在5GC上注册之后的任何时间，UE根据IMS注册过程在S-CSCF注册。UE在UL NAS传输消息中将注册信息流作为NAS容器发送给AMF，该容器包括公共用户身份、私有用户身份、归属网络域名等。在UL NAS传输消息中添加NAS容器类型，以指示该容器用于IMS注册。Step S6202: At any time after registration on 5GC, the UE registers with the S-CSCF according to the IMS registration procedure. The UE sends the registration information flow as a NAS container to the AMF in a UL NAS transport message, which includes the public user identity, private user identity, home network domain name, etc. The NAS container type is added in the UL NAS transport message to indicate that the container is for IMS registration.

AMF从UE接收UL NAS传输消息。基于NAS容器类型“IMS注册”，AMF选择P-CSCF，例如，基于AMF上的预配置，AMF将注册信息流转发给P-CSCF。AMF receives UL NAS transport message from UE. Based on NAS container type "IMS Registration", AMF selects P-CSCF, e.g. For example, based on the pre-configuration on AMF, AMF forwards the registration information flow to P-CSCF.

收到注册信息流后，PCSCF将向SCSCF发送注册信息流：PCSCF地址/名称、公共用户身份、私有用户身份、PCSCF网络标识符。P-CSCF将UE(UE ID)与AMF(AMF ID或IP地址)绑定，用于UE的以下信令交互。After receiving the registration information flow, PCSCF will send the registration information flow to SCSCF: PCSCF address/name, public user identity, private user identity, PCSCF network identifier. P-CSCF binds UE (UE ID) with AMF (AMF ID or IP address) for the following signaling interaction of UE.

在IMS注册成功后，UE接收来自AMF的IMS 200 OK，该IMS 200 OK位于DL NAS传输消息的容器中。After successful IMS registration, the UE receives an IMS 200 OK from the AMF, which is located in the container of the DL NAS transport message.

步骤S6203：S-CSCF检查在IMS注册过程中从HSS检索的初始过滤标准。Step S6203: The S-CSCF checks the initial filtering criteria retrieved from the HSS during the IMS registration process.

步骤S6204：在成功的IMS注册之后，基于检索到的初始过滤标准，S-CSCF通知IP-SM-GW(AS)关于用户的注册。当UE的IMS订阅简档中没有MSISDN时，IMSI被通知给IPSMGW(AS)。Step S6204: After successful IMS registration, based on the retrieved initial filtering criteria, the S-CSCF notifies the IP-SM-GW (AS) about the user's registration. When there is no MSISDN in the UE's IMS subscription profile, the IMSI is notified to the IPSMGW (AS).

步骤S6205：IP-SM-GW(AS)向S-CSCF返回OK。Step S6205: IP-SM-GW (AS) returns OK to S-CSCF.

步骤S6206：IP-SM-GW(AS)向HSS发送IP-SM-GW注册请求。Step S6206: IP-SM-GW (AS) sends an IP-SM-GW registration request to HSS.

步骤S6207：如果需要或对于没有移动站综合业务数字网络(MSISDN，Mobile Station IntegratedServices Digital Network)的MT-SMS，HSS存储接收到的IP-SM-GW地址，如果设置了消息等待标志，则使用它作为UE可通过IMS访问的指示，以触发警报服务中心消息，并使用IPSMGW注册Res对IP-SM-GW(as)做出响应。IPSMGW从注册事件包中获得用于没有电话URI的SMS递送的多媒体公共标识(IMPU，IP Multimedia Public Identity)。Step S6207: If needed or for MT-SMS without Mobile Station Integrated Services Digital Network (MSISDN), the HSS stores the received IP-SM-GW address and, if the message waiting flag is set, uses it as an indication that the UE is accessible via IMS to trigger an alert service center message and responds to the IP-SM-GW (as) using the IPSMGW Registration Res. The IPSMGW obtains the IP Multimedia Public Identity (IMPU) for SMS delivery without a phone URI from the Registration Event Package.

步骤S6208：在HSS上成功注册IPSMGW地址后，HSS检查是否存储了消息等待数据，并使用TS 23.040中描述的过程向所有SC发出警报。Step S6208: After successfully registering the IPSMGW address on the HSS, the HSS checks whether message waiting data is stored and alerts all SCs using the procedure described in TS 23.040.
