detailed description

FIG. 1 is a schematic diagram of a network architecture according to an embodiment of the present application. As shown in FIG. 1 , the network architecture is specific. The network side can be divided into a UE side and a network side, wherein the network side can further include a radio access network (Radio Access Network, RAN), a core network (Core Network), and a network slice controller (slice-controller). The radio access network may include a centralized unit (CU) and a distributed unit (DU). The CU can be used for the baseband signal processing, and the DU can be used for the radio frequency signal receiving and processing. The DU and the CU can be the base station of the radio access network. For example, the DU can be a radio remote unit (Radio Remote Unit, RRU for short). The CU may be a Building Base Band Unit (BBU). The core network (Core Network) mainly includes a Control Plane (CP) and a User Plane (UP). The CP is mainly used to manage radio resources, establish wireless connections, and service quality. Quality of Service (QoS) guarantee and final resource release. UP is mainly used to process all information sent and received by users. The network slice controller can be specifically used for authentication authentication, network slice management, and the like.

The method for establishing a network slice of the present application mainly relates to the UE shown in FIG. 1, the base station of the radio access network, the CP of the core network, and the network slice controller. The CP is mainly deployed in the mobility management entity (Mobility Management Entity, MME) or the gateway device (GW) of the core network. Therefore, in the subsequent embodiments of the present application, the communication network element may refer to the base station or the CP is deployed. MME or GW. Of course, it can be understood that the CP can also be deployed in the network element device of other core networks, which is not limited by this embodiment.

If the base station implements the network slice establishment method in the embodiment of the present application as the communication network element, the network slice setup request message sent by the UE is processed by the base station when the base station of the access network is reached, as shown in FIG. The UE may send a network slice setup request message to the base station through an interface between the UE and the base station, and after the base station performs related processing, the generated signaling is sent to the network slice controller through the interface. In the process of actually transmitting the signaling to the network slice controller, the physical path may pass through the core network device, but the core network device only forwards it and does not process it. Therefore, logically, the network slice sent by the UE is logically The setup request message arrives at the base station and is then sent by the base station to the network slice controller.

If the MME or the GW in which the CP is deployed is used as the communication network element to implement the method for establishing the network slice in the embodiment of the present application, the network slice setup request message sent by the UE is transparently transmitted by the base station to the MME or GW of the core network, and the CP is deployed. The MME or the GW performs related processing. As shown in FIG. 1 , the network slice setup request message sent by the UE reaches the MME or the GW through the interface, and then the related processing is performed by the MME or the GW, and the generated signaling is sent to the network slice through the interface. The controller actually forwards the signal through the base station, but the base station only forwards it and does not process it. Therefore, logically, the network slice setup request sent by the UE arrives at the MME or GW, and then is used by the MME or GW. Send to the network slice controller.

It should be noted that, in the embodiment of the present application, the “communication network element sends an X message to the terminal” specifically refers to: when the communication network element is a base station, the base station sends an X message to the terminal, and when the communication network element is In the case of the MME or the GW, the MME or the GW sends an X message to the terminal through the base station. The X message can be any message, which is not illustrated here.

The foregoing UE may be a terminal, and the terminal involved in the embodiment of the present application specifically refers to a device that provides voice and/or data connectivity, including a wireless terminal or a wired terminal. The wireless terminal can be a handheld device with wireless connectivity, or other processing device connected to a wireless modem, and a mobile terminal that communicates with one or more core networks via a wireless access network. For example, the wireless terminal can be a mobile phone (or "cellular" phone) and a computer with a mobile terminal. Another example is that the wireless terminal can also be portable and pocket-sized. Mobile, handheld, computer built-in or in-vehicle mobile devices. For another example, the wireless terminal can be part of a mobile station, an access point, or a user equipment (UE).

The network slice may be specifically included in the network slice instance, and may also include multiple network slice instances. When the network slice includes a network slice instance, the network slice type information of the network slice may be used to identify the network slice instance. When the network slice includes multiple network slice instances, each network slice instance may be set to correspond to one identifier, that is, the network slice instance is identified by the identifier information of the network slice instance.

The "transport resource corresponding to the network slice" refers to the air interface time-frequency resource or the bearer resource corresponding to the network slice, that is, the air interface time-frequency resource or bearer resource allocated by the network side to the network slice, wherein the private air interface The time-frequency resource refers to the network side that divides the air interface resources between the radio access network side and the UE side. Different air interface time-frequency resources correspond to different network slices. The specific bearer resources specifically refer to the radio access network does not support the network. Slice technology, different network slices use proprietary bearer resources, and use public air interface resources. The air interface time-frequency resource may be specifically described by using time-frequency resource information, and the time-frequency resource information may include information such as a spectrum bandwidth, a spectrum position, and a transmission time interval (TTI) scheduling period. For a network slice type or for all users in a network slice instance, the location and time of the transmission resource can be dynamically changed for different users. The bearer resource may be specifically described by bearer information. The bearer information may specifically include a bearer identifier, a scheduling priority, codec information, a number of retransmissions, and the like.

The network segment identification information, the network slice type information, and the network slice instance identification information are as follows. .

This document also relates to "configuration information of network slice" and "network configuration information", wherein "configuration information of network slice" specifically refers to a network slice that the network side (communication network element or network slice controller) has determined to establish a terminal request to establish. The configuration information of the network slice corresponds to the network slice, and the “network configuration information” specifically refers to the configuration information required by the network side to establish the network slice instance that the terminal requests to establish, but needs to be configured. The configuration information of the network slice is determined according to the network slice establishment request message and the network configuration information. That is, the network configuration information is usually saved in the network slice controller, or may be sent by the network slice controller to the communication network element, and the communication network element determines the configuration information of the network slice according to the network slice establishment request message and the network configuration information sent by the terminal.

The configuration information of the network slice may specifically include a set of function modules required for establishing a network slice, a deployment location of each function module, and a required computing resource.

FIG. 2 is a flowchart of a method for establishing a network slice according to another embodiment of the present application. As shown in FIG. 2, the method in this embodiment may include:

Step 201: The terminal sends a first network slice setup request message to the communication network element, where the communication network element receives the first network slice setup request message sent by the terminal. The first network slice setup request message includes identifier information of the terminal and network slice request information.

Specifically, the network slice request information may include any one of service identification information, service quality of service (QoS) information, and network slice template parameter information, or a combination thereof. The network operator can customize multiple network slice templates, and each network slice template can be associated with one type of network slice, and the terminal sends the network slice template parameter information of the network slice to be established to the communication network element, so that the communication network element The type information of the network slice that the terminal needs to establish is determined according to the network slice template parameter information. Network slice The template parameter information may specifically include any one or a combination of delay information, rate information, packet loss rate information, bit error rate information, network slice size information, network slice resource requirement information, and network slice deployment policy information.

Step 202: The communication network element determines network slice type information according to the first network slice setup request message.

Specifically, after receiving and identifying the first network slice setup request message sent by the terminal, the communication network element determines the network slice type information according to the first network slice setup request message. The specific implementation manner may be that the communication network element determines the network slice type information according to the network slice request information in the first network slice setup request message, that is, determines the network according to at least one of the service identifier information, the service QoS information, and the network slice template parameter information. Slice type information. The network slice type information may specifically be a network slice type identifier (type ID) information. An optional implementation manner, the communication network element may store the service identification information, or the service QoS information or the network slice template parameter information, and the mapping relationship with the network slice type information, and the communication network element receives the first sent by the terminal. The network slice establishment request message is used to determine the network slice type information corresponding to the network slice that the terminal requests to establish according to the mapping relationship. In another optional implementation manner, the mapping relationship may also be pushed by the network slice controller to the communication network element before step 101. The service QoS information may specifically include delay information, rate information, packet loss rate information, and bit error rate information.

It should be noted that, because the network slice request information in step 201 specifically includes any one of service identification information, service QoS information, and network slice template parameter information, or a combination thereof, step 202 needs to be performed to determine according to the network slice request information. Network slice type information. In another optional implementation manner, the network slice request information in the step 201 may include the network slice type information, and the step 202 is not performed.

Step 203: The communication network element sends a second network slice setup request message to the network slice controller, where the network slice controller receives the second network slice setup request message sent by the communication network element.

Specifically, the second network slice setup request message may specifically include network slice type information, identifier information of the terminal, and identifier information of the communication network element.

Step 204: The network slice controller authenticates the terminal according to the identification information of the terminal.

Specifically, after receiving the second network slice setup request message sent by the communication network element, the network slice controller may perform authentication on the terminal according to the identifier information of the terminal carried in the second network slice setup request message, and determine whether the terminal can be The network slice corresponding to the network slice type information is newly created. If yes, the network slice controller determines the configuration information of the network slice according to the network slice type information, the identification information of the communication network element, and the network configuration information, and performs step 105.

Step 205: The network slice controller sends a second network slice setup response message to the communication network element, where the communication network element receives the second network slice setup response message sent by the network slice controller.

The second network slice setup response message includes configuration information of the network slice.

Specifically, the network slice controller returns a second network slice setup response message to the communication network element according to the identifier information of the communication network element and the network slice type information. The second network slice setup response message may specifically include configuration information of the network slice, and may further include network slice identification information and identification information of the terminal. The configuration information of the network slice may specifically include a function module set required for establishing a network slice, a deployment location of each function module, and a required computing resource, and a network slice type corresponding to a function module set, and a network slice type. One or more network slice instances may be corresponding, each network slice instance has unique identification information of network slice instances, and network slice instances of the same network slice type have the same set of function modules. Functional mode The block set may specifically include each functional module and a connection relationship of each functional module, and each network slice instance corresponds to configuration information of one network slice instance.

Step 206: The communication network element configures the network slice according to the configuration information of the network slice, and completes establishing the network slice.

Specifically, after receiving the second network slice setup response message sent by the network slice controller, the communication network element may trigger the establishment of the network slice according to the configuration information of the network slice.

Step 207: The communication network element sends a first network slice setup response message to the terminal, where the terminal receives the first network slice setup response message sent by the communication network element.

The first network slice setup response message may include network slice identification information.

Specifically, the network slice identifier information may be the identifier information of the network slice instance, or may be the network slice type information corresponding to the network slice instance, and may be flexibly set according to requirements.

Step 208: The terminal determines, according to the network slice identification information, a transmission resource corresponding to the network slice, and performs data transmission by using the transmission resource corresponding to the network slice.

The transmission resource may specifically include an air interface time-frequency resource or a bearer resource, and the air interface time-frequency resource corresponding to the network slice may be any one of a specific frequency point, a specific sub-carrier, a specific sub-carrier width, and a specific TTI scheduling period, or Its combination. It can be specifically indicated by time-frequency resource information. The bearer resource corresponding to the network slice may specifically be a specific logical path for data transmission between the terminal and the network side. That is, the network side establishes a network slice unique to the terminal according to the network slice establishment request of the terminal, and the terminal can perform data transmission by using the transmission resource corresponding to the network slice.

After the network slice is established through steps 201 to 207, the terminal can immediately use the network slice for data transmission, or use the network slice for data transmission after a period of time.

In this embodiment, the first network slice establishment request message is sent by the terminal to the communication network element, and the communication network element determines the network slice type information according to the first network slice establishment request message, and the second network slice establishment request including the network slice type information is used. The message is sent to the network slice controller, and the network slice controller sends the configuration information of the network slice to the communication network element, and the communication network element completes the configuration of the network slice according to the configuration information of the network slice, and establishes a new network slice as the terminal. The transmission resources required for the network segmentation are provided, so that the terminal can perform data transmission through the newly established network slice, thereby realizing flexible and dynamic network segmentation according to the terminal data transmission requirement, thereby effectively improving the utilization of network resources.

The technical solutions of the method embodiment shown in FIG. 2 are described in detail below by using several specific embodiments.

The application scenario of the embodiment shown in FIG. 3 is that the first network slice setup request message sent by the terminal is sent by the default network slice of the communication system, and the radio access network supports the network slice technology, that is, multiple networks can be divided from the air interface side. Slices, different time-frequency resources of different locations correspond to different network slices, so that flexible allocation of network-time time-frequency resources to network slices can be flexibly based on the data transmission requirements of each network slice, which can effectively improve network resource utilization. . The embodiment shown in FIG. 3 will specifically explain how to establish a network slice of the embodiment of the present application in the application scenario.

FIG. 3 is a flowchart of a method for establishing a network slice according to another embodiment of the present application. The first network slice setup response message in the embodiment of the present application may include network slice identifier information, time-frequency resource information of a network slice, and whether it is needed. Re-accessing the information, so that the terminal accesses the time-frequency resource corresponding to the network slice for data transmission. As shown in FIG. 3, the method in this embodiment may include:

Step 301: Establish a default network slice.

Specifically, the communication network element and the network slice controller deploy a default network slice, for example, an Enhanced Mobile Broadband (EMBB) large traffic network slice as a default network slice, or a Long Term Evolution (LTE). The network acts as the default network slice.

Step 302: The terminal accesses a default network slice.

Step 303: The communication network element sends a first broadcast message to the terminal, where the terminal receives the first broadcast message sent by the communication network element.

Specifically, the communication network element may periodically send the first broadcast message, where the first broadcast message may include network slice type information that is supported by the network element, and may include air interface time-frequency resource information corresponding to the network slice type information, and At least one of service identification information, service QoS information, and network slice template parameter information corresponding to the network slice type information. The network slice type information that the communication network element is supporting specifically refers to the network slice type information corresponding to the network slice currently in the active state or running in the communication network element.

It should be noted that, because the terminal receives the first broadcast message sent by the communication network element, after the terminal accesses the default slice, the terminal may also access the default slice before the terminal accesses the default slice.
