The above-mentioned network side device 12 may be a 5G network side device (for example: gNB, 5G NR NB), or may be a 4G network side device (for example: eNB), or may be a 3G network side device (for example: NB), or a subsequent evolution The network-side device in the communication system, etc. It should be noted that the specific type of the network-side device 12 is not limited in this embodiment of the present invention.
图2是本发明实施例提供的应用于图1所示的网络系统的重定向方法的流程图。如图2所示，该方法包括以下步骤：FIG. 2 is a flowchart of a redirection method applied to the network system shown in FIG. 1 provided by an embodiment of the present invention. As shown in Figure 2, the method includes the following steps:
步骤201：网络侧设备向终端发送第一消息，所述第一消息包括重定向指示信息，所述重定向指示信息用于指示所述终端从第一网络切片重定向至N个第二网络切片。Step 201: The network side device sends a first message to the terminal, the first message includes redirection instruction information, and the redirection instruction information is used to instruct the terminal to redirect from the first network slice to N second network slices .
上述N为大于或等于1的整数，也就是说，网络侧设备可以向终端指示一个重定向(redirection)的网络切片，网络侧设备也可以向终端指示多个重定向的网络切片，以供终端选择。上述网络切片可以指接入网(Radio Access Network，RAN)切片(简称RAN slice或RAN slicing)。The above-mentioned N is an integer greater than or equal to 1, that is to say, the network side device can indicate a redirected network slice to the terminal, and the network side device can also indicate multiple redirected network slices to the terminal for the terminal choose. The foregoing network slicing may refer to access network (Radio Access Network, RAN) slicing (RAN slice or RAN slicing for short).
步骤202：终端接收所述第一消息。Step 202: The terminal receives the first message.
终端在接收到网络侧设备发送的第一消息之后，可以从第一消息中获取到第一消息中携带的重定向指示信息。终端在获取到重定向指示信息之后，可以根据重定向指示信息进行重定向行为。After receiving the first message sent by the network side device, the terminal may acquire the redirection indication information carried in the first message from the first message. After obtaining the redirection instruction information, the terminal may perform a redirection behavior according to the redirection instruction information.
进一步的，终端的重定向行为可以是向N个第二网络切片中的一第二网络切片发起连接，或者，还可以是向N个第二网络切片中的一第二网络切片发起业务请求。即，终端可根据重定向指示信息，向N个第二网络切片中的一第二网络切片发起连接或业务请求。Further, the redirection behavior of the terminal may be to initiate a connection to a second network slice among the N second network slices, or may also be to initiate a service request to a second network slice among the N second network slices. That is, the terminal can initiate a connection or service request to a second network slice among the N second network slices according to the redirection indication information.
进一步的，终端在获取到重定向指示信息之后，可以在进入空闲态(idle)或非激活态(inactive)之后，根据重定向指示信息，向N个第二网络切片中的一第二网络切片发起连接或业务请求。Further, after the terminal obtains the redirection indication information, after entering the idle state (idle) or the inactive state (inactive), according to the redirection indication information, a second network slice among the N second network slices Initiate a connection or service request.
现有机制中，网络重定向功能只能实现将终端从一个小区切换至另一个小区。然而，在网络切片技术中，当重定向的小区包含多个网络切片时，终端重定向时无法立刻选择所需要的网络切片，终端切换小区后还需要重选或再切换到所需要的网络切片，这导致终端业务中断，从而导致终端重定向后的业务质量不能保证。In the existing mechanism, the network redirection function can only realize the handover of the terminal from one cell to another. However, in the network slicing technology, when the redirected cell contains multiple network slices, the terminal cannot immediately select the required network slice when redirecting, and the terminal needs to reselect or switch to the required network slice after switching cells , which leads to the interruption of terminal services, resulting in that the service quality after terminal redirection cannot be guaranteed.
本发明实施例中，在网络切片技术中，通过网络侧设备向终端指示网络切片的重定向指示信息，终端能够根据重定向指示信息重定向到合适的网络切片。这样，能够避免在网络切片重定向中，因终端无法选择所需要的网络切片而导致终端业务中断的问题，从而能够提高终端业务的可靠性，能够确保终端在网络切片重定向中的业务质量。In the embodiment of the present invention, in the network slicing technology, the network side device indicates the redirection indication information of the network slice to the terminal, and the terminal can be redirected to an appropriate network slice according to the redirection indication information. In this way, the problem of terminal service interruption caused by the terminal being unable to select the required network slice during network slice redirection can be avoided, thereby improving the reliability of terminal service and ensuring the service quality of the terminal during network slice redirection.
图3是本发明实施例提供的应用于网络侧设备的重定向方法的流程图。如图3所示，重定向方法，应用于网络侧设备，该方法包括以下步骤：Fig. 3 is a flowchart of a redirection method applied to a network side device provided by an embodiment of the present invention. As shown in Figure 3, the redirection method is applied to the network side device, and the method includes the following steps:
步骤301：向终端发送第一消息，所述第一消息包括重定向指示信息，所述重定向指示信息用于指示所述终端从第一网络切片重定向至N个第二网络切片。Step 301: Send a first message to a terminal, where the first message includes redirection instruction information, and the redirection instruction information is used to instruct the terminal to redirect from a first network slice to N second network slices.
上述N为大于或等于1的整数，也就是说，网络侧设备可以向终端指示一个重定向的网络切片(即第二网络切片)，网络侧设备也可以向终端指示多个重定向的网络切片，以供终端选择。上述网络切片可以指接入网切片。The above N is an integer greater than or equal to 1, that is to say, the network side device may indicate to the terminal a redirected network slice (that is, the second network slice), and the network side device may also indicate multiple redirected network slices to the terminal , for terminal selection. The foregoing network slicing may refer to access network slicing.
对于终端而言，终端可以接收网络侧设备发送的第一消息，终端在接收到网络侧设备发送的第一消息之后，可以从第一消息中获取到第一消息中携带的重定向指示信息。终端在获取到重定向指示信息之后，可以根据重定向指示信息进行重定向行为。For the terminal, the terminal may receive the first message sent by the network side device, and after receiving the first message sent by the network side device, the terminal may obtain the redirection indication information carried in the first message from the first message. After obtaining the redirection instruction information, the terminal may perform a redirection behavior according to the redirection instruction information.
进一步的，终端的重定向行为可以是向N个第二网络切片中的一第二网络切片发起连接，或者，还可以是向N个第二网络切片中的一第二网络切片发起业务请求。即，终端可根据重定向指示信息，向N个第二网络切片中的一第二网络切片发起连接或业务请求。Further, the redirection behavior of the terminal may be to initiate a connection to a second network slice among the N second network slices, or may also be to initiate a service request to a second network slice among the N second network slices. That is, the terminal can initiate a connection or service request to a second network slice among the N second network slices according to the redirection indication information.
进一步的，终端在获取到重定向指示信息之后，可以在进入空闲态或非激活态之后，根据重定向指示信息，向N个第二网络切片中的一第二网络切片发起连接或业务请求。Further, after obtaining the redirection indication information, the terminal may initiate a connection or service request to a second network slice among the N second network slices according to the redirection indication information after entering the idle state or the inactive state.
上述重定向指示信息用于向终端指示重定向的网络切片，因此，上述重定向指示信息可以包括第二网络切片的相关信息。The above redirection indication information is used to indicate the redirected network slice to the terminal, therefore, the above redirection indication information may include related information of the second network slice.
可选的，所述重定向指示信息包括以下至少一项：Optionally, the redirection indication information includes at least one of the following:
所述N个第二网络切片的标识信息；Identification information of the N second network slices;
所述N个第二网络切片的RACH(Random Access Channel，随机接入信道)资源指示信息；RACH (Random Access Channel, random access channel) resource indication information of the N second network slices;
所述N个第二网络切片的频域指示信息。Frequency domain indication information of the N second network slices.
例如，重定向指示信息可以包括以下任一项：For example, redirection instructions can include any of the following:
N个第二网络切片的标识信息；Identification information of the N second network slices;
N个第二网络切片的标识信息以及N个第二网络切片对应的RACH资源指示信息；Identification information of the N second network slices and RACH resource indication information corresponding to the N second network slices;
N个第二网络切片的标识信息以及N个第二网络切片对应的频域指示信息；Identification information of the N second network slices and frequency domain indication information corresponding to the N second network slices;
N个第二网络切片的标识信息以及N个第二网络切片对应的RACH资源指示信息和频域指示信息。Identification information of the N second network slices and RACH resource indication information and frequency domain indication information corresponding to the N second network slices.
对于终端而言，上述第一网络切片可以为终端发起第一业务请求的网络切片，或者，为终端进行第一业务的网络切片，因此，可以将第一网络切片理解为与终端存在业务关联的网络切片。上述第二网络切片为终端可以重定向的网络切片，因此，可以将第二网络切片称为重定向的网络切片。For the terminal, the above-mentioned first network slice can be a network slice for the terminal to initiate the first service request, or a network slice for the terminal to perform the first service. Therefore, the first network slice can be understood as a service associated with the terminal Network slicing. The above-mentioned second network slice is a network slice that can be redirected by the terminal, therefore, the second network slice can be called a redirected network slice.
由于上述第一网络切片既可以为终端发起第一业务请求的网络切片，也可以为终端进行第一业务的网络切片，因此，第一消息既可以是RRC(Radio Resource Control，无线资源控制)重配消息，也可以是RRC释放消息。Since the above-mentioned first network slicing can be the network slicing that initiates the first service request for the terminal, and can also perform the network slicing for the first service for the terminal, the first message can be RRC (Radio Resource Control, radio resource control) heavy configuration message, or an RRC release message.
具体的，当上述第一网络切片为终端发起第一业务请求的网络切片时，此时终端还未与第一网络切片建立连接，因此，第一消息为RRC重配消息，用于为终端重新配置供终端重定向的第二网络切片。当上述第一网络切片为终端进行第一业务的网络切片时，此时终端已经与第一网络切片建立连接，因此，第一消息为RRC释放消息，用于释放终端并为终端重新配置供终端重定向的第二网络切片。Specifically, when the above-mentioned first network slice is the network slice for the terminal to initiate the first service request, the terminal has not established a connection with the first network slice at this time, therefore, the first message is an RRC reconfiguration message, which is used to reconfigure the terminal for the terminal. Configure a second network slice for endpoint redirection. When the above-mentioned first network slice is a network slice for the terminal to perform the first service, the terminal has established a connection with the first network slice at this time, therefore, the first message is an RRC release message, which is used to release the terminal and reconfigure the terminal for the terminal Redirected second network slice.
