Detailed Description
For a clearer understanding of the objects, technical solutions and advantages of the present application, the present application is described and illustrated below with reference to the accompanying drawings and examples.
In the multi-base station intelligent scheduling method for communication switching, a plurality of first base stations and second base stations with different frequencies are respectively called to form a plurality of macro cells and micro cells. The mobile device traverses a plurality of macro cells and micro cells on a motion path, and a relay station is responsible for communication between a wireless terminal and a base station. The invention determines the first pre-switching position and the second pre-switching position according to the communication accessibility probability, and realizes the switching between the source second channel and the target second channel. Meanwhile, the relay station decouples the communication data into control data and user data according to the characteristics of the communication protocol, and intelligently allocates communication resources.
Example 1
As shown in fig. 1 to 2, the multi-base station intelligent scheduling method for communication handover according to the present embodiment includes the following steps:
step 1: and calling a plurality of first base stations to construct a first network, calling a plurality of second base stations to construct a second network, wherein the first network is provided with a plurality of macro cells, the second network is provided with a plurality of micro cells, and the first base stations are connected with the second base stations through optical fibers. The network formed by the first base stations is a first network, the communication frequency of the first base stations is 700MHz to 6GHz, and the communication frequency of the second base stations is 24GHz to 100GHz. The first network covers a series of macro cells, each macro cell having a larger coverage area. The second network covers a series of microcells for further enhancing network coverage and channel quality. In order to realize data communication between two networks, the first base station and the second base station are connected through optical fibers.
Step 2: the plurality of wireless terminals are located in the mobile device, the mobile device moves along a movement path, the movement path passes through the plurality of macro cells and the micro cells simultaneously, the adjacent macro cells have macro overlapping areas, and the adjacent micro cells have micro overlapping areas. This step involves a plurality of wireless terminals located inside the mobile device, such as a mobile phone, a computer, etc. held by the passengers in the high-speed rail, the motor vehicle, etc. As the mobile device moves along a given railway line or highway line, it passes through a plurality of macro cells and micro cells. Between adjacent macro cells or micro cells, there are macro overlap areas and micro overlap areas, and wireless terminals in these areas can receive signals of the adjacent macro cells or micro cells at the same time.
Step 3: the wireless terminal is connected to a relay station of the mobile device, the relay station establishes a source first channel for transferring control data with the first base station, and the relay station establishes a source second channel for transferring user data with the second base station. The relay station plays a role in data transfer. The wireless terminal sends the communication data to the relay station, and the relay station decouples the communication data into control data and user data according to the communication protocol characteristics. As shown in fig. 3, control data is transmitted to the first base station and user data is transmitted to the second base station. In this embodiment, the protocol type field is TCP or UDP, decoupled into user data, and the protocol type field is ICMP or IGMP, decoupled into control data.
Step 4: after the mobile equipment enters the macro overlapping area, the relay station replaces the target first channel with the source first channel according to the channel quality of the source first channel and the target first channel established by the other first base station. The present embodiment does not limit the switching condition entering the macro overlapping area, and may use the channel quality in the prior art as a reference index, where the channel quality is determined based on the SINR measurement value of the downlink channel. Since the first base station is only used for transmitting control data, the data volume is smaller, and the rigid switching can improve the switching efficiency without affecting the user experience.
Step 5: the relay station extracts communication speed characteristics of a plurality of wireless terminals, calculates communication accessibility probability according to the communication speed characteristics, and then determines a first pre-switching position and a second pre-switching position. As shown in fig. 4, the present invention determines a first pre-switching position and a second pre-switching position in a micro-overlapping area, so as to implement flexible switching of channels. Calculating communication accessibility probability P according to communication speed characteristics, and a first pre-switching position L 1 =S 2 P+S 1 (1-P) the motion path passes through the micro-overlap region, S 1 S is the starting point position of the motion path in the micro-overlap region 2 Is the end position of the motion path in the micro-overlap region.
Second pre-switch position L 2 =S 1 P+S 2 (1-P). The communication speed characteristics comprise sampling time interval t, sampling point number N of error code, running speed v of mobile equipment at sampling time and communication accessibility probabilityLambda is the variance of the poisson distribution. Setting the lower limit std of the error rate to be 0.008, and if the error rate is higher than 0.008, defining that the sampling point generates error code.
Step 6: and after the mobile equipment reaches the first pre-switching position, the relay station sends a double access request, and the relay station establishes a target second channel with another second base station. The dual access request refers to that the relay station accesses two second base stations simultaneously, and the two second base stations complete the tasks of data receiving and retransmitting of the relay station simultaneously. Typically a relay station sets up multiple radio interfaces or radio interfaces supporting multiple modes (e.g. LTE and 5G). In a specific embodiment, the relay station sends a dual access request to the first base station, the first base station transmits the dual access request to the second base station through the optical fiber, and the second base station responds to the dual access request to establish the target second channel.
Step 7: the relay station extracts communication protocol characteristics of a plurality of wireless terminals, and allocates communication resources to the wireless terminals according to the communication protocol characteristics. The relay station first satisfiesAnd the communication requirement of the train is met, and the residual resources are allocated to the wireless terminal. Generating resource weight according to the communication protocol characteristics, and distributing the bandwidth of the relay station according to the proportion of the resource weight. Resource allocation weights for communication dataThe communication data consists of m resource blocks, Q i For priority, delta, determined from the communication protocol characteristics of resource block i in the communication data i Upper limit of time-out rate for receiving resource block i for relay station, R max For maximum upload rate of resource block i, < > for>For the average upload rate of resource block i, D i For the queue delay of the packet in the resource block i, T i Maximum queue delay allowed for resource block i.
Q i The determination may be based on the communication protocol characteristics of the resource block, for example, the priority of the protocol type field is 2, for example, the priority of the protocol type field is 1, for example, ICMP or IGMP, and the numerical value of QCI (Quality of Service Class Identifier) may be referred to specifically. In another embodiment, the priority is determined according to the importance of the user plane data, such as voice, streaming media, etc., where the importance of the data is higher, such as offline video, text, etc. For example, the priority of voice may be set to 1, the priority of text may be set to 2, and the priority of offline video may be set to 4.
Step 8: and after the mobile equipment reaches the second pre-switching position, the relay station sends a single access request, and the relay station replaces the target second channel with the source second channel. Because the single access request is control plane data, the relay station transmits the single access request to the first base station, and the first base station transmits the single access request to the second base station. In a single access environment, the source second channel is switched off and the target second channel becomes the new source second channel.
Example two
Further, the embodiment provides a method for switching the target first base station in the macro overlapping area. The embodiment adopts rigid access to improve the switching efficiency of the first base station. As shown in fig. 3, the detailed steps of the switching method are as follows:
step 201: the relay station establishes a source first channel with the source first base station, and the relay station sends control data to the service gateway through the source first channel. After the mobile device enters the macro overlapping area, the relay station starts to monitor the channel quality of the source first channel in real time.
Step 202: the relay station initiates a handover notification to the source first base station. After receiving the switching notification, the source first base station feeds back to the relay station that the switching request has been received, and starts switching preparation work.
Step 203: the source first base station transmits a handover request to the target first base station. The handover request includes key information such as an ID of the relay station, cell information, a moving direction of the mobile device, and the like.
Step 204: after receiving the handover request, the target first base station evaluates whether the handover can be accepted according to its own network conditions and the requirements of the mobile device. If the evaluation is acceptable, the target first base station will reply to the source first base station with handover feedback.
Step 205: after receiving the handover feedback of the target first base station, the source first base station starts to send a data switching signal and a reconfiguration signal to the relay station.
Step 206: after receiving the data switching signal and the reconfiguration signal sent by the source first base station, the relay station initiates a data synchronization signal to the target first base station. The data synchronization signal contains information such as the communication state of the mobile device, the resource configuration of the source first base station, and the like.
Step 207: and the target first base station sends the synchronous feedback information and the uplink configuration information. The synchronous feedback and uplink configuration information comprise information such as resource configuration, network environment and the like of the target first base station.
Step 208: and after receiving the uplink configuration information, the relay station sends a synchronous confirmation signal and a switching completion signal to the target first base station.
Step 209: and after receiving the synchronous confirmation signal and the switching completion signal, the target first base station starts to provide service for the mobile equipment and releases the cache data. At this time, the establishment of the target first channel is completed, and the relay station is connected to the service gateway through the target first channel, so that the continuous transmission of the user data is realized. At the subsequent moment, the relay station monitors the channel quality of the target first channel in real time, and terminates the source first channel according to the channel quality.
Example III
The second base station is used for transferring user data, so that invocation and handover of the second base station requires control data by means of the first base station. The handoff procedure is long in duration and the amount of user data of the second base station is large. The embodiment provides a method for switching a target second base station in a micro-overlapping area. The embodiment adopts flexible access to finish the transmission of partial data in advance. As shown in fig. 4, the detailed steps of the switching method are as follows:
step 301: and in the moving process of the equipment, the relay station establishes stable connection with the source second base station and the service gateway through the source second channel. The high frequency and high density characteristics of the source second base station provide high-speed and high-quality signal access, and ensure stable network connection of the mobile equipment in high-speed movement.
Step 302: after the mobile equipment reaches the first pre-switching position, the source first base station receives a pre-switching feedback signal of the relay station and sends a cooperation request to the target second base station (micro cell), and the purpose of the request is to enable the source first base station, the source second base station and the target second base station to work cooperatively to finish smooth switching of the mobile equipment. And after receiving the cooperation request signal, the target second base station replies a cooperation feedback signal.
Step 303: after receiving the cooperative feedback signal, the source first base station further sends a dual access request to the service gateway. So that the source second base station and the target second base station can receive the data transmitted by the service gateway at the same time to ensure the continuity of the data transmission. After receiving the dual access request, the service gateway feeds back a dual-broadcast acknowledgement signal to the source first base station.
Step 304: after the dual access is started, the target second channel is established, and the relay station sends user data to the service gateway through the target second channel.
Step 305: the relay station sends pre-switching feedback to the source first base station, and the source first base station sends a handover request to the target second base station after receiving the feedback. And the target second base station sends the handover feedback to the source first base station after receiving the handover request.
Step 306: and the source first base station initiates data switching to the relay station after receiving the handover feedback. And the relay station immediately synchronizes the data to the target second base station after receiving the data switching signal, and the target second base station sends synchronous feedback to the source first base station after receiving the data.
Step 307: and the source first base station immediately transmits uplink configuration data to the relay station after receiving the synchronous feedback. After receiving the uplink configuration data, the relay station adjusts its own uplink configuration and sends a synchronization acknowledgement signal to the source first base station.
Step 308: and after the mobile equipment reaches the second pre-switching position, a single access request is sent to the first base station, the target second base station executes the cooperative exit operation, and the source second channel is terminated.
