Background
With the rapid development of CIoT (cellular Internet of things) technology and business and the gradual maturity of NFV (Network Function Virtualization) technology, a physical Network can be divided into a plurality of virtual networks, i.e., Network slices, according to different service requirements. The CIoT service of the eMTC (enhanced Machine Type Communication) has a larger difference from the service characteristics and traffic model of the conventional MBB (Mobile Broadband). Therefore, in order to fully utilize network resources, improve the resource utilization rate and reduce the overall network deployment cost, different core network slices need to be deployed for subsequent MBB and eMTC.
However, eMTC and LTE (Long Term Evolution) belong to the same radio access type, so that eNB (Evolved Node Base station) needs additional assistance to select the core network slice. The related core network slice selection technology mainly comprises two solutions of D cor and eDecor.

Fig. 1 illustrates a flow diagram of some embodiments of a routing system of the present disclosure.
As shown in fig. 1, the routing system 1 includes a UE 11 and an eNB 12.
The UE 11 sends a connection request and a connection setup complete message, which may be an RRC connection setup complete message. And under the condition that the UE 11 is the eMTC terminal, the UE 11 sets the CIoT capability parameter as a necessary parameter of the connection establishment completion message. Therefore, whether the UE 11 is an eMTC terminal or an MBB terminal can be judged by judging whether the connection establishment completion message contains the CIoT capability parameter, and the network slice for routing is determined according to the CIoT capability parameter.
For example, the CIoT capability parameter may include at least one of UP-CIoT-EPS-optimization (CIoT user plane optimization scheme), CP-CIoT-EPS-optimization (CIoT control plane optimization scheme).
The eNB 12 transmits a connection establishment instruction to the UE 11 in response to the connection request from the UE 11. For example, the UE 11 transmits an RRC connection request, and the eNB 12 transmits an RRC connection establishment instruction. After establishing the RRC connection, the UE 11 returns an RRC connection establishment completion message to the eNB 12. The eNB 12 determines whether the RRC connection setup complete message returned by the UE includes a CIoT capability parameter.
Unlike the existing 3GPP standards, in some embodiments in the present disclosure, UP-CIoT-EPS-optimization and CP-CIoT-EPS-optimization are set as mandatory parameters of the eMTC terminal, and a value of "True" for these parameters indicates that the corresponding optimization scheme is supported, and a value of "False" for the corresponding optimization scheme is not supported. Therefore, the routing network slice can be judged through the CIoT capability parameter, and whether an optimization scheme is adopted or not can be controlled.
The eNB 12 routes the UE 11 to the MBB core network slice in response to the connection setup complete message not including the CIoT capability parameter. The eNB 12 routes the UE to the eMTC core network slice in response to the CIoT capability parameter being included in the connection setup complete message. For example, routing may be achieved by sending an initialization UE message to the destination core network slice, where the initialization UE message may include an attach request. The routing technical scheme does not need redirection, does not need to increase signaling load of an S1 interface, has low requirements on the terminal and the base station, and does not need to increase any extra parameter for the terminal.
In order to more clearly illustrate the data interaction process of the routing system, the technical solution of the present disclosure is described below by using a signaling diagram in fig. 2.
Fig. 2 illustrates a signaling diagram of some embodiments of the routing system of the present disclosure.
As shown in fig. 2, in event 210, the UE sends an RA Preamble (random access Preamble) to the eNB, for example, the UE may perform cell selection after powering on, receive a system message, prepare to start attachment, and then send the RA Preamble to the eNB.
In event 220, the eNB returns an RA Response (random access Response) to the UE in Response to the RA Preamble.
In event 230, the UE sends an RRC connection setup request to the eNB after receiving the RA Response.
In event 240, the eNB sends an RRC connection setup message to the UE in response to the connection setup request.
In event 250, the UE establishes an RRC connection and then sends an RRC connection setup complete message to the eNB. And in the case that the UE is the eMTC terminal, setting CIoT capability parameters UP-CIoT-EPS-optimization and CP-CIoT-EPS-optimization in the RRC connection establishment completion message as the necessary parameters of the eMTC terminal. Meanwhile, NAS (Non-access stratum) Attach signaling can be triggered to Attach.
In event 260, the eNB determines whether the UP-CIoT-EPS-optimization and CP-CIoT-EPS-optimization are included in the RRC connection setup complete message. If included, an event 270 is triggered, otherwise an event 280 is triggered.
In event 270, the eNB routes the initialize UE message to the MME (Mobility Management Entity) of the MBB slice. The initial UE message route includes an Attach Request (Attach Request).
In event 280, the eNB routes the initialize UE message to the MME of the eMTC slice. The initialization UE message routing includes an Attach Request.
In the above embodiment, the CIoT capability parameter is set as a parameter that is necessary for the connection establishment completion message of the eMTC terminal, and the core network slice of the route is determined according to whether the connection establishment completion message includes the CIoT capability parameter. The scheme can automatically select the route under the condition of not increasing any network signaling burden, thereby realizing the isolation of the network slice, reducing the difficulty of network planning and improving the utilization rate of network resources.
Fig. 3 illustrates a flow diagram of some embodiments of a routing method of the present disclosure.
As shown in fig. 3, in step 310, the eNB sends a connection establishment instruction to the UE in response to a connection request from the UE.
In step 320, the UE establishes an RRC connection in response to the connection establishment instruction, and then returns a connection establishment complete message to the eNB. For example, the connection setup complete message is an RRC connection setup complete message. And under the condition that the UE is the eMTC terminal, the UE sets the CIoT capability parameter as the necessary parameter of the connection establishment completion message. The CIoT capability parameter includes at least one of a CIoT user plane optimization scheme and a CIoT control plane optimization scheme.
In step 330, the eNB determines whether the connection setup complete message includes a CIoT capability parameter. If not, the UE is routed to the MBB core network slice (step 340), e.g., an initialize UE message is sent to the MBB core network slice. If so, the UE is routed to the eMTC core network slice (step 350), e.g., an initialize UE message is sent to the eMTC core network slice. The attach request may be included in the initialize UE message.
In the above embodiment, the CIoT capability parameter is set as a parameter that is necessary for the connection establishment completion message of the eMTC terminal, and the core network slice of the route is determined according to whether the connection establishment completion message includes the CIoT capability parameter. The scheme can automatically select the route under the condition of not increasing any network signaling burden, thereby realizing the isolation of the network slice, reducing the difficulty of network planning and improving the utilization rate of network resources.
Fig. 4 shows a block diagram of further embodiments of a routing device of the present disclosure.
As shown in fig. 4, the apparatus 4 of this embodiment includes: a memory 41 and a processor 42 coupled to the memory 41, the processor 42 being configured to perform the routing method in any of the embodiments of the present disclosure based on instructions stored in the memory 41.
The memory 41 may include, for example, a system memory, a fixed non-volatile storage medium, and the like. The system memory stores, for example, an operating system, an application program, a Boot Loader (Boot Loader), a database, and other programs.
