Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of wireless computing power networks, and in particular to a mobility management method, base station, device and medium for a wireless computing power network. Background Art

[0002] In recent years, the Internet of Things and smart machines have flourished, and new business forms, new scenarios and new models have continued to emerge, making all walks of life have more urgent demands for communication and computing, such as low latency and deterministic performance assurance. Therefore, operators have proposed computing networks, aiming to use communication networks as a bridge to provide real-time, green and intelligent computing power for business intelligence. In wireless access networks, the trends of intelligence, cloudification and openness are becoming increasingly clear. Wireless access networks have gradually become edge computing platforms for general computing integration, with the potential for low latency and deterministic services. They are potential high-quality computing power that needs to be developed and utilized urgently.

[0003] Mobility management is a basic function of wireless networks, which is used to ensure that users can obtain services without interruption while moving. In wireless computing networks, base stations provide both wireless connections and computing services. Mobility management involves switching and service migration to ensure that connected users can continue to obtain connection services and computing services while moving. However, existing networks can only support switching, and cannot perform mobility management between computing base stations to ensure user service performance. In the traditional switching execution process, switching only considers the signal quality of the user, without considering service migration on the one hand, and ignoring factors such as computing performance and overhead on the other hand. In mobile edge computing, switching and migration are managed and decided in isolation, ignoring switching overhead and wireless status, which is prone to frequent switching overhead and cannot guarantee user performance. Therefore, in wireless computing networks, more intelligent mobility management solutions are needed. Summary of the invention

[0078] Perform handover and migration based on traditional protocols;

[0079] After the handover and migration are completed, the user terminal accesses the target cNB through the target gNB.

[0080] In the embodiment of the present invention, optionally, the logical connection base station and the logical computing base station interact through a first interface; the first interface is used to connect the logical connection base station and the logical computing base station under the same base station, and is used to transmit at least one of the following: computing power information request and computing power information;

[0081] or,

[0082] The wireless resource management module and the computing resource management module interact through a first interface; the first interface is used to connect the wireless resource management module and the computing resource management module under the same base station, and is used to transmit at least one of the following: computing power information request and computing power information.

[0083] In the embodiment of the present invention, the information of the first interface is shown in Table 1:

[0084] Table 1

[0101]

[0102] In the embodiment of the present invention, through the extended design of the interface, the interface can meet the needs of each module, complete the distributed mobility management centered on user performance, and ensure the continuity of wireless connection and computing power services.

[0103] In the embodiment of the present invention, it is taken as an example that the autonomous driving vehicle uploads the target recognition task in the autonomous driving process to the base station side for processing:

[0104] Because the vehicle needs to ensure the continuity and timeliness of the task during movement, that is, the end-to-end delay needs to be less than τ;

[0105] by Figure 2 Taking the structure in as an example, the process of the mobility management method of the wireless computing network is as follows:

[0106] The source gNB and the source cNB jointly monitor the end-to-end delay of the user. If the end-to-end delay is higher than τ, communication perception and computing power perception are triggered. The delay τ is the end-to-end delay, which can be further expressed as:

[0107] (1) Service applications do not access across base stations. That is, the cNB and gNB deployed in the service application are in the same base station and there is no backhaul delay. The end-to-end delay τ is:

[0108] τ=Radio Transmission Delay+Computing Delay;

[0109] Among them, Radio Transmission Delay is the wireless transmission delay in Table 6, which is the air interface delay, which is the service data volume divided by the air transmission rate. According to Shannon's formula, the air interface delay can be expressed as:

[0110] Where B is the channel bandwidth; ph is the signal power; N o is the noise power;

[0111] Computing Delay is the computing delay, which is the amount of computing divided by the number of times the computing resource processes the calculation in 1 second. The computing power is measured in FLOPS, and the specific calculation is:

[0112] Wherein, ComputingResourceLoad is the computing resource load in Table 2, Table 4 or Table 6;

[0113] (2) Service applications access across base stations, that is, the cNB and gNB deployed on the service application are not in the same base station, and there is a backhaul delay. The end-to-end delay τ is:

[0114] τ=Radio Transmission Delay+Computing Delay+Wired Transmission Delay;

[0115] Among them, Radio Transmission Delay is the wireless transmission delay in Table 6, is the air interface delay, which is the service data volume divided by the air transmission rate. According to the Shannon formula, the air interface rate can be expressed as:

[0116] Where B is the channel bandwidth; ph is the signal power; N o is the noise power;

[0117] Computing Delay is the computing delay, which is the amount of computing divided by the number of times the computing resource processes the calculation in 1 second. The computing power is measured in FLOPS, and the specific calculation is:

[0118] Wherein, ComputingResourceLoad is the computing resource load in Table 2, Table 4 or Table 6;

[0119] Wired Transmission Delay is the wired transmission delay in Table 6, which can be obtained through testing, or by dividing the service message size by the wired bandwidth in Table 6. Usually, images and the like have protocol provisions for message formats and sizes, which can be calculated through image resolution, size, color depth, and compression algorithm.

[0120] The source gNB obtains the measurement report from the user terminal UE, as well as the base station load and remaining bandwidth of itself and the optional gNB as shown in Table 1;

[0121] The source cNB requests the computing power information of the registered optional cNB and sends it to the source gNB. The specific information is shown in Table 3.

[0122] Assume that the remaining resources of the first base station gNB m are represented as {B m ,F m}, where: B m , is the remaining air interface bandwidth of the first base station, used to calculate the air interface delay; F m A computing capability provided to the first base station for calculating a computing delay;

[0123] The signal to interference plus noise ratio (SNR) between the UE and the first base station gNB m is SNR um ;

[0124] The bandwidth between the UE and the target base station gNB m′ is B mm′ , the wired transmission delay is t mm′ ;

[0125] According to the above delay calculation formula, the first base station obtains the computing power information of the optional base station through the first interface and the second interface;

[0126] The best switching and migration decision is selected from the optional base stations gNB and gNC, and the best migration node is selected based on τ; the best switching and migration decision needs to meet the following requirements: the end-to-end delay τ meets the requirements and the stability of the service is guaranteed, that is, the service interruption time is minimized or the overhead is minimized, where the overhead is the frequent transmission of VM / instance file data required for service migration, which consumes transmission resources;

[0127] After selecting the target base station, that is, the best switching node and migration node, switching and migration can be performed at the appropriate node according to the predetermined procedure.
