Description

Method and device for accessing network slice

This application claims the priority of the Chinese Patent Application, filed on Dec. 07, 2016, filed on Dec. in.

Technical field

The present application relates to the field of network technologies, and in particular, to a method and an apparatus for accessing network slices.

Background technique

In the current LTE network, the basic process of the user equipment accessing the network is as follows: the user equipment receives the master information module broadcasted by the base station (English: Master Information Block, MIB for short), and determines the system information module 1 according to the MIB (English: System Information Block 1) For example, the time-frequency position of the SIB1 is received, and the SIB1 broadcasted by the base station is received at the time-frequency position of the SIB1, and the scheduling information of all system information (English: System Information, referred to as SI) carried in the SIB1 is obtained, and the scheduling information from the SI is obtained. The time-frequency position of the SIBn (n>1) other than SIB1 is obtained, and finally the network access information required for accessing the network is received at the time-frequency position of the SIBn, and the LTE network is accessed.

In the fifth-generation mobile communication technology (English: 5th-Generation, 5G for short) network, a physical network can be used because the quality of service corresponding to different network application scenarios is different (English: Quality of Service, QoS for short). It is divided into multiple logical networks that support different network application scenarios. One network application scenario supports one type of service, and one logical network is a network slice. Different network slices correspond to different services and QoS, and different QoS requires frequency. The system parameters such as downlink bandwidth information, uplink and downlink ratio information, timer information, and counter information are different.

Since the concept of network slicing is not involved in the current LTE network, the MIB and the SIB1 broadcasted by the LTE network are all the same system parameters. Therefore, regardless of the services performed by the user equipment, the same network is accessed. Obviously, currently The broadcast method does not apply to 5G networks with multiple network slices.

The technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

In the following, some possible network architectures applicable to the embodiments of the present application are introduced in conjunction with FIG. 1A and FIG. 1B.

FIG. 1A shows a network system that may be applicable to an embodiment of the present application. As shown in FIG. 1A, the user equipment accesses a carrier Internet protocol (English: Internet Protocol, IP for short) service network through a radio access network and a core network, such as a multimedia subsystem (English: IP Multimedia System, IMS for short) Network, Packet Switched Streaming Service (PSS) network.

In addition, it can also be applied to subsequent evolution systems of the LTE system, such as a next-generation network system, that is, a 5G system.

FIG. 1B shows a possible network architecture provided by an embodiment of the present application. The function of the user equipment in FIG. 1A may be specifically implemented by the user equipment 120 in FIG. 1B. The function of the radio access network in FIG. 1A may be specifically implemented by the base station 140 and the like in FIG. 1B. As shown in FIG. 1B, the network architecture includes: a user equipment 120 and a base station 140.

User equipment 120 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of mobile stations (English: Mobile Station, MS for short), terminal devices ( English: terminal device) and so on. For convenience of description, the devices mentioned above are collectively referred to as user devices.

Base station 140 is a device deployed in a radio access network to provide wireless communication functionality to a terminal. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In a system using different radio access technologies, the name of a device having a base station function may be different. For example, in an LTE system, an evolved Node B (English: evolved NodeB, eNB or eNodeB for short), In 3G communication system In it, it is called Node B (English: Node B) and so on. For convenience of description, in the embodiment of the present application, the foregoing apparatus for providing a wireless communication function for a terminal is collectively referred to as a base station.

A wireless connection is established between the base station 140 and the user equipment 120 through a wireless air interface (which may also be referred to as an air interface or an air interface). In addition, the base station 140 and the user equipment 120 can also communicate with each other through the air interface technology. Optionally, the wireless air interface is a wireless air interface based on the 5G standard, for example, the wireless air interface is a New Radio (NR); or The wireless air interface may also be a wireless air interface based on the 5G-based next-generation mobile communication network technology standard.

At present, the MIB and the SIB1 broadcasted by the LTE network are the same set of system parameters. Therefore, the current network broadcast mode is not applicable to the 5G network of the multi-network slice. In the embodiment of the present application, the first system sent by the user equipment from the base station is used. Obtaining a second time-frequency location in the information, receiving, by the second time-frequency location, the first network access information sent by the base station, and accessing the first network slice according to the first network access information, where the first system information includes at least one time The frequency position corresponds to the network access information of the network slice, so that the broadcast mode is applicable to the 5G network of the multi-network slice, and the user equipment can access the network slice that needs to be accessed.

The embodiments of the present application are further described in detail below based on the common aspects related to the embodiments of the present application.

Network slicing technology refers to constructing one or more logical networks supporting different service characteristics on a physical facility. The logical network includes a set of connection relationships between a set of physical function instances and physical function instances. After implementing the network slicing technology, the network architecture will no longer be a "one size fits all" form of the traditional cellular network, but can be customized for different functions. From the perspective of service type, network slicing can be specifically defined as one or more combinations of hardware, software, policies, and spectrum that the network operator dynamically deploys to meet the QoS of a particular set of users.

At present, the 5G network defines three typical application scenarios, namely Enhanced Mobile Broadband (English: Enhance Mobile Broadband, referred to as: eMBB), ultra-high reliability and ultra-low latency communication (English: Ultra Reliable & Low Latency Communication, Abbreviation: uRLLC) and Massive Machine Type Communication (MMTC). For the three typical scenarios defined by 5G networks, 5G networks can be divided into three types of network slices: eMBB, mMTC and uRLLC. Since the network access information of the network slice is related to the service characteristics of the network slice, the network access information of the network slice of different service characteristics is different, and the current system parameters carried by the MIB and the SIB1 broadcasted by the LTE network are the same. Therefore, the current LTE network broadcast mode is not applicable to a 5G network with multiple network slices.

Example 1

Please refer to FIG. 2 , which is a flowchart of a method for accessing a network slice provided by an embodiment of the present application. The method includes the following steps:

Step 201: The base station sends first system information to the user equipment at the first time-frequency location, where the first system information includes at least a second time-frequency location. Correspondingly, the user equipment receives the first system information sent by the base station at the first time-frequency location.

The first system information mentioned herein includes the MIB or the SIB1, that is, the MIB or the SIB1 sent by the base station to the user equipment includes at least a second time-frequency location, where the second time-frequency location refers to the transmission of the first network slice. The time-frequency position occupied by the broadcast information.

When the MIB includes the second time-frequency location, the MIB may further include a downlink bandwidth, a physical hybrid automatic repeat indication channel (English: Physical Hybrid ARQ Indicator Channel, PHICH for short) resource indication, and a single frequency network (English: Single Frequency Network) , referred to as: SFN) system frame number, Cyclic Redundancy Code (English: Cyclic Redundancy Code, referred to as: CRC), the number of antennas and other information.

When the second time-frequency location is included in the SIB1, the SIB1 may further include a scheduling information list (English: Scheduling Info List), where the Scheduling Info List includes scheduling information of other SIBs except SIB1 and related to other cell accesses. information.

Optionally, the user equipment pre-stores the correspondence between the first system information and the first time-frequency location, and receives the first system information sent by the base station at the first time-frequency location.

Optionally, after receiving the first system information sent by the base station, the user equipment parses the first system information, and stores a time-frequency location corresponding to each network access information in the first system information.

Step 202: The user equipment acquires a second time-frequency location from the first system information.

Step 203: The base station sends the first network access information to the user equipment at the second time-frequency location. Correspondingly, the user equipment receives the first network access information sent by the base station at the second time-frequency location.

Specifically, when the user equipment needs to access the first network slice, the first network access information sent by the base station is received at the second time-frequency location, where the first network access information includes at least the user equipment accessing the first network. The necessary information of the slice, such as the scheduling period (Transmission Time-Interval, TTI for short) related to the first network slice, the frequency point and the downlink bandwidth information.

Optionally, the first network access information further includes information such as uplink and downlink proportion information, timer information, and counter information related to the first network slice.

Corresponding relationship between the first network slice and the first network access information, and the correspondence between the second time-frequency location and the first network access information may be configured online by a radio slice controller (English: Radio Slice Controller agent, referred to as: RSC) It can also be configured offline by a technician.

It should be noted that the RSC may be set on the base station as a functional module of the base station, or may be independently set outside the base station and connected to the base station.

When the base station configures the correspondence between the network slice and the first network access information, and the corresponding relationship between the time-frequency location and the first network access information, the base station configures the first network corresponding to the first network slice and the first network slice. The access information also configures a second time-frequency location corresponding to the first network access information according to the first network access information.

It should be noted that the first network access information corresponding to each network slice configuration and the time-frequency location corresponding to each first network access information may be changed according to actual conditions.

Step 204: The user equipment accesses the first network slice according to the first network access information.

In the solution provided by the embodiment of the present application, the second time-frequency location is obtained by the user equipment from the first system information sent by the base station, and the first network access information sent by the base station is received by the second time-frequency location, according to the first network connection. The incoming information accesses the first network slice, and the first system information includes at least one time-frequency location, where the time-frequency location corresponds to network access information of the network slice, thereby achieving a 5G network in which the broadcast mode is applicable to multiple network slices. The user equipment can access the effect of the network slice that needs to be accessed.

In a possible implementation manner, the first system information further includes a network access information pair of the second network slice. The second network slice is a network slice different from the first network slice. Still referring to FIG. 2, the method for accessing the network slice further includes:

Step 201a: The base station sends the first system information to the user equipment at the first time-frequency location, where the first system information includes at least a second time-frequency location and a time-frequency location corresponding to the second network slice. Correspondingly, the user equipment receives the first system information sent by the base station at the first time-frequency location.

Step 202a: The user equipment acquires a time-frequency location corresponding to the second network slice from the first system information.

In step 203, the base station sends the second network access information corresponding to the second network slice to the user equipment at the time-frequency location corresponding to the second network slice. Correspondingly, the user equipment receives the second network access information sent by the base station at a time-frequency location corresponding to the second network slice.

Different network slices correspond to different services and QoS. The system parameters such as the frequency, downlink bandwidth information, uplink and downlink ratio information, timer information, and counter information required by different QoS are different, because the network access information corresponding to the network slice is At least the TTI, the frequency point, and the downlink bandwidth information related to the network slice are included, so the network access information corresponding to different network slices is different, that is, the TTI, the frequency point, and the first network access information and the second network access information The downlink bandwidth information is different.

Step 204a: The user equipment accesses the second network slice according to the second network access information.

It should be noted that, since step 204a is similar to step 204, step 204a will not be described in detail in this embodiment.

In this embodiment, the first system information broadcasted by the base station to the plurality of user equipments includes a time-frequency location corresponding to the plurality of network access information, so that the user equipment that receives the first system information needs to receive the network access information corresponding to the network information. Time-frequency position.

In a possible implementation manner, when the first system information is the MIB, the base station sends the MIB to the user equipment in the PBCH of the central frequency band.

The base station can configure different system information for the network slice with different characteristics according to the characteristics of the network slice, and configure a corresponding transmission period for each system information. For example, for the network slice required to access the network slice and the user-free device access time within 10 ms of the user equipment, the base station needs to encapsulate the time-frequency location of the network slice accessed by the user equipment within 10 ms into a system information, and no user is required.

For example, the uRLLC slice requires the user equipment to quickly access the uRLLC slice. In order to prevent the user equipment from waiting for a long time to obtain the network access information corresponding to the uRLLC slice, the uRLLC slice cannot be quickly accessed. In this embodiment, The RSC can configure, for each network slice, a transmission period of the QoS or the access requirement that satisfies the service type of the network slice, for example, the RSC is a transmission period in which the network slice required to be accessed by the user equipment within 10 ms is configured within 10 ms.

Step S2: The base station sends the first network access information to the user equipment at the second time-frequency location according to the sending period of the first network access information.

Step 311: The user equipment accesses the first network slice according to the first network access information.

In a practical application, the user equipment may access the first network slice corresponding to the first network access information according to the first network access information, where the first network slice is A network slice that satisfies the QoS of the target service.
