Background technique

Differentiated business models and business needs bring great challenges to the future wireless mobile broadband system in terms of frequency, technology and operation. The traditional communication network, namely the Access Network (RAN) + core Network (CORE), more and more unable to meet all scenarios. And building a private network for each kind of scene will cause a lot of waste of resources, which is not practical.

The development of Network Function Virtualization (NFV) technology enables operators to build different virtual networks for different business needs. Network slicing is based on a common physical infrastructure, logically defining and dividing the network to form an end-to-end virtual network. Each virtual network has different functional characteristics to dynamically meet various needs and business models.

A typical network slice includes a set of virtualized access network functions and core network functions. The network slice is built by the operator according to the requirements and policies. The functions included in a network slice are also determined by the operator according to the requirements and policies. For example, some network slices may include a dedicated forwarding plane in addition to the control plane functionality; some network slices may include only some basic control plane functions.

FIG. 1 is a schematic diagram of a network slice in the related art. As shown in FIG. 1 , a common network (Common Network), and customized A, B, and C network slice categories. The Common Network provides services for general-purpose services; and customized network slicing provides three different types of services (for example: Type A is ultra-high-speed services such as video services, virtual reality, etc.; Type B is bursty small business data services) , such as QQ, WeChat, etc.; type C is low-latency ultra-reliable business, For example, the vehicle network, the smart grid, etc., each type generates different network slice instances according to some differences (for example, service requirements and business models are different, for example, type A performs video services, and service rate requirements according to video types) It is divided into slice A1 that supports normal video and slice A2 that supports HD video. A network slice forms a virtual network that provides a specific mobile network access service for the user terminal (UE).

The priority of the cell to the cell of the type that does not support the network slice. High-priority network slicing means that the base station should try to ensure the continuity of such network slicing. The low-priority network slicing represents the continuity of the high-priority network slicing as much as possible when the base station cannot guarantee the continuity of its network slicing.

The handover to the cell that does not support the network slice service refers to the cell switching from the support network slice type cell to the cell that does not support the network slice, because the base station to which the network slice type cell belongs is not supported may not acquire the network from the source base station. The type information is sliced, so the terminal can send a message to the network again to update the network slice priority information.

The terminal may obtain the terminal network slice priority information by using at least one of the following manners: by pre-configuration; configuring the RRC message from the eNB through the radio resource control; configuring from the core network through the non-access stratum message (NAS); The message is obtained from the application server, for example, from the server.

Step 2, local processing by the base station

After receiving the slicepriority message, the eNB allocates appropriate token bucket parameters for each logical channel of the terminal according to the priority. For example, if the priority of a network slice is relatively high, the assigned priority bit rate PBR and the token bucket size are The duration BSD is longer. If the priority of a network slice is relatively low, the assigned priority bit rate PBR and the token bucket size duration BSD are shorter.

Step 3: The base station provides logical channel configuration parameters to the terminal

An existing RRC message, such as an MBMSInterestIndication message, may also be multiplexed; the message is added with an identifier to support parameters related to the network slicing function, for example, a network slice indication.

In step 3, the source base station decides to switch to initiate an S1 handover.

The eNB selects a network slice cell including the terminal support in the optional handover cell according to the terminal support network slice priority indication. If no cell support completely includes the network slice type of the terminal interest, the cell including the network slice of the terminal interest is preferentially selected, and the priority of the network slice is used as a reference. For example, cell priority selection that supports high priority network slice types.

The source base station may obtain the neighbor cell support network slice type information by using inter-base station message or pre-configuration.

Step 3: The source base station determines to perform X2 handover according to the measurement situation of the terminal and the network configuration; the source base station preferentially selects the neighboring cell supporting the high priority service according to the network slice priority;

Step 4: The source base station sends a handover request message to the target base station; the message includes network slice priority information, where the information includes a network slice priority level;

The handover request message used in the foregoing operation may be a HANDOVER REQUEST message of the X2 interface, or may be a new message;

The network slice priority information can use the new field in the message; it can also be carried in the existing field in the message body.

The priority is represented by a bit value in the message. For example, if it is 1, it indicates that the network slice function discovery/communication priority is supported.

The priority can also be represented by a field. If the field exists, it indicates that the support network slice function discovery takes precedence over the communication.

Step 5: After receiving the handover request message, the target base station performs local processing such as admission control and resource allocation according to the network slice priority information of the UE.

If the target base station cannot support multiple network slices at the same time due to traffic congestion, the partial service is rejected according to the network slice priority in the network slice priority information, and the rejected service information is passed. The handover response message is sent to the source base station;

If the admission part is successful, the target base station will return a handover response message containing the rejected service information;

If all the failures are accepted, the target base station will return a handover failure message;

In the case of successful and partially successful, the target base station saves the network slice priority information, for example, the UE is in the context of the target eNB, and the target base station refers to the source base station configuration to allocate resources for the UE;

Step 6, the target base station sends a handover request acknowledgement message (HANDOVER REQUEST ACKNOWLEDGE) to the source base station;

The rejected service information is included in the message. If the basic service (such as MBB) is rejected, it can be carried in the E-RABs Failed to Setup List field in the S1 message, or through the E-RABs Not Admitted List field of the X2 interface. Carrying; can also be carried in the message body using a new field; if the non-essential service is rejected (for example, MMTC network slice), it can be carried by adding a field, which is used by the source base station to identify which services are rejected; or in the S1 message. The E-RABs Failed to Setup List field is carried or carried through the E-RABs Not Admitted List field of the X2 interface; if the non-essential service is rejected (for example, MMTC network slice), you can use the new field or use the X2 field.

Obtained from the source base station. FIG. 10 is a schematic diagram of a network slice priority processing method according to a preferred embodiment 5 of the present invention. As shown in FIG. 10, the method includes the following steps:
