Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an information processing method, device, network side equipment and wireless backhaul equipment. Background Art

[0002] In emergency communication and other scenarios, due to the random location and short deployment time, there are generally no conditions for the deployment of optical fiber. Generally, one of satellite, microwave, and 5G CPE (customer premise equipment) relay is used as the backhaul link to build the NG and / or S1 interface transmission between the base station and the core network. According to different scenarios, choose the appropriate backhaul link solution for deployment. For example, in the emergency scenario of urban firefighting, microwave, satellite and other signals are easily blocked by buildings, etc., and a more stable backhaul link can be established by using 5G CPE relay; in the emergency scenario of forest fire, there is generally no 5G signal coverage, and microwave or satellite backhaul is more appropriate.

[0003] However, in the scenario without fiber backhaul, the existing solution cannot automatically select and switch the backhaul link, and cannot adaptively select the appropriate backhaul link, which may lead to poor experience of delay-sensitive services (such as voice services).

[0288] It is noted here that the first threshold and the second threshold described below are both related to the backhaul device and the frequency band used to measure the link quality information. Different thresholds may be set for different frequency bands and / or different backhaul devices.

[0291] Furthermore, in the case where the wireless backhaul device is a customer premises equipment CPE, it also includes: determining the available frequency and total bandwidth resources corresponding to the first network side device and the CPE, and the coverage requirement information corresponding to the first network side device; receiving the first frequency and the first bandwidth corresponding to the searched signal sent by the CPE; determining the backhaul frequency, backhaul bandwidth, base station coverage frequency and base station coverage bandwidth according to the available frequency, total bandwidth resources, the first frequency and the first bandwidth corresponding to the searched signal, and the coverage requirement information; determining whether the backhaul frequency, backhaul bandwidth, base station coverage frequency and base station coverage bandwidth meet the fifth preset condition; if the fifth preset condition is not met, sending frequency bandwidth adjustment information to the second base station; wherein the fifth preset condition includes a service requirement condition or a preset rate condition; the frequency bandwidth adjustment information is used to instruct the second base station to reduce the occupied frequency and bandwidth resources.

[0292] In this way, frequency coordination can be automatically achieved. Specifically, the CPE first measures the frequency bands and bandwidth information (i.e., the first bandwidth mentioned above) used by the surrounding cells, and informs the first network side device. The first network side device determines the frequency bands, bandwidths, frame structures, etc. used by the first network side device for coverage and backhaul links based on the remaining available frequency bands and bandwidths (i.e., the above-mentioned available frequencies and total bandwidth resources), coverage requirements (i.e., coverage requirement information), and service bandwidth requirements (i.e., the cell division requirement information described below); if the current remaining available frequency bands and bandwidths cannot meet the requirements, the first network device can inform the CPE. The coverage requirement information includes the coverage radius, coverage area, etc. required by the service, that is, the coverage radius, area and other information that the first network side device needs to provide; the service bandwidth requirement is known by the first network side device itself, and can be input into the first network side device in advance, or obtained by the first network side device according to the QFI (QoS flow identifier) ​​and / or slice identifier; the service bandwidth requirement may include three aspects: one is the backhaul service bandwidth requirement (that is, the backhaul service requirement described below), such as video services and command information that need to be backhauled to the remote control center; one is the public network service bandwidth requirement corresponding to the first network side device (that is, the public network requirement described below), such as voice, video calls and other service requirements; one is the private network service bandwidth requirement corresponding to the first network side device (that is, the private network requirement described below), such as video services, temperature / humidity / smoke density and / or pressure and other status data service requirements.

[0293] The "available frequencies and total bandwidth resources corresponding to the first network side device and the CPE" may be confirmed based on locally pre-stored information, and the specific available frequencies and total bandwidth resources corresponding to the first network side device and the CPE are pre-stored locally. It can also be understood that the available frequencies and total bandwidth resources are the frequencies and total bandwidths supported by the CPE and the first network side device.

[0295] Among them, the cell division demand information includes backhaul service demand and the public network demand and private network demand corresponding to the first network side device (connected to the wireless backhaul device), but is not limited to this.

[0296] Furthermore, when the wireless backhaul device is not a CPE, the cell division (including frequency, bandwidth, frame structure, etc.) can be determined based on the available frequency and total bandwidth resources corresponding to the pre-stored first network side device, as well as the public network requirements and private network requirements, that is, the cell division of the first network side device (corresponding to the coverage scenario); the frequency band and bandwidth, frame structure, etc. required for the backhaul link can also be determined based on the backhaul service requirements.

[0304] In this way, frequency coordination can be automatically achieved. Specifically, when the backhaul device is CPE, it is necessary to measure the frequency and bandwidth information of the surrounding cells and feed the results back to the first network side device. More specifically, CPE automatically searches for signals from the surrounding cells, and records the cell ID, cell frequency band, cell bandwidth and other information corresponding to each cell and feeds it back to the emergency base station (corresponding to the first network side device).

[0327] It is to be noted that the second embodiment can refer to the relevant contents of the first embodiment, which will not be repeated here.

[0328] The information processing method provided by the embodiment of the present invention is further described below in combination with multiple sides such as the first network side device and the wireless backhaul device.

[0329] In response to the above technical problems, an embodiment of the present invention provides an information processing method, which can be specifically implemented as a method for adaptive selection of backhaul links and automatic frequency coordination, involving how to adaptively complete backhaul link selection in a variety of backhaul link scenarios to ensure service experience, and automatically complete the frequency coordination process to avoid interference. Specifically, this solution can select a suitable link for backhaul based on factors such as the quality of each link (corresponding to the above link quality information), the type of service transmitted (corresponding to the above target service type information), and the cost (corresponding to the above backhaul cost information), and automatically complete the frequency selection process; this solution mainly involves the following two parts:

[0330] Part 1, link adaptation selection scheme (the first network side device takes an emergency base station as an example, and the types of wireless backhaul devices take three as examples):

[0331] (1) The emergency base station can simultaneously connect to three types of communication equipment (collectively referred to as wireless backhaul equipment) via wired means, such as Figure 5 As shown, the emergency base station is represented by the active antenna processing unit AAU and the baseband processing unit BBU in the figure. The AAU and the BBU are connected by optical fiber, and the BBU is connected to three wireless backhaul devices through network cables, including microwave equipment, satellite mobile receiving equipment (i.e., satellite equipment) and CPE;

[0332] (2) According to the service type to be transmitted in the emergency base station (which can be understood as the service type transmitted by the backhaul link, corresponding to the above service type information), the priorities of the three backhaul links are automatically set or adjusted:

[0333] 1) Pre-setting: Before establishing an end-to-end communication link, determine the service type to be prioritized, such as voice service, picture transmission, etc., according to customer requirements (corresponding to the above-mentioned determination of the backhaul link priority information according to the pre-setting);

[0334] 2) Network judgment: The emergency base station sets or adjusts the priority of the backhaul link according to the service type received for the first time or multiple times (which can be judged by QFI (QoS flowID, QoS flow identifier) ​​and / or slice identifier, etc.) (corresponding to the above-mentioned determination of the backhaul link priority information according to the received service type information);

[0335] For example, when the service is a voice service, it is more sensitive to latency, and the backhaul link priority is CPE>microwave>satellite; when the service is a picture or video service, it has a higher rate requirement, and the backhaul link priority is microwave>CPE>satellite; if the service has a higher requirement for reliability, multiple backhaul links can be automatically established at the same time, and the same data can be transmitted on different backhaul links to achieve repeated data transmission and backup as well as uninterrupted service (at least one backhaul link can be used for data transmission).

[0336] (3) According to the determined priority order of the backhaul links, the backhaul link quality is measured from high to low, and the emergency base station is informed. The emergency base station determines the backhaul link to be used based on the link quality, service type, cost and other factors (multiple backhaul links can be established at the same time), and automatically completes the establishment of the end-to-end link (corresponding to the above-mentioned after receiving the link quality information sent by all devices in the at least one type of wireless backhaul device, according to the link quality information and preset parameter information, the target backhaul link is selected from the backhaul links corresponding to the at least one type of wireless backhaul device); or, the link quality is measured from high to low and at least one end-to-end link is attempted to be established. If the establishment is successful (corresponding to the first parameter value in the above-mentioned link quality information being greater than or equal to the second threshold) and the number of established backhaul links meets the service requirements (if the service requires the establishment of two backhaul links, the link is stopped after the two backhaul links are established). If not, the link quality measurement is performed, and the link quality measurement of the next priority level is started. (Corresponding to the above-mentioned determination of whether the received link quality information satisfies the third preset condition after receiving the link quality information sent by the wireless backhaul device; if so, the backhaul link corresponding to the wireless backhaul device is used as the target backhaul link; and whether the current backhaul link satisfies the fourth preset condition; if not, the link quality information sent by the next wireless backhaul device is continuously received, and the determination of whether the received link quality information satisfies the third preset condition after receiving the link quality information sent by the wireless backhaul device is returned to the execution; wherein, the third preset condition includes that the first parameter value in the link quality information is greater than or equal to the second threshold value; and the fourth preset condition includes that the second parameter value of the backhaul link is greater than or equal to the service demand value).

[0337] Specifically, the emergency base station may notify the wireless backhaul device to perform measurements (corresponding to the above-mentioned sending of link quality test indications to the at least one type of wireless backhaul device respectively according to the backhaul link priority information; receiving the link quality information sent by the at least one type of wireless backhaul device according to the link quality test indication); or, the backhaul device may autonomously measure under preset conditions (such as power-on) (corresponding to the above-mentioned receiving of link quality information sent by at least one type of wireless backhaul device under a first preset condition; the first preset condition includes completion of power-on).

[0338] (4) When the emergency base station moves, causing the quality of at least one backhaul link to change or be interrupted, the emergency base station triggers the switching of the backhaul link, and performs backhaul link measurement according to the priority of the backhaul link (specifically, the emergency base station may notify the wireless backhaul device to perform the measurement), adaptive selection, and automatic establishment process (corresponding to the above-mentioned second preset condition, again receiving the link quality information sent by at least one type of wireless backhaul device; selecting the target backhaul link from the backhaul links corresponding to the at least one type of wireless backhaul device according to the link quality information and preset parameter information; wherein the second preset condition includes: the channel quality of at least one backhaul link is lower than the first threshold and / or at least one backhaul link is interrupted).

[0339] 1) When the channel quality of the backhaul equipment (including microwave equipment, satellite mobile receiving equipment, CPE, etc.) is lower than the configured threshold (corresponding to the first threshold above), the switching process of the backhaul link is triggered. The configured threshold can be the threshold at which each backhaul equipment cannot provide network services or cannot guarantee the service experience; and / or,

[0340] 2) When the network where the backhaul device is located is interrupted, the switching process of the backhaul link is triggered.

[0341] Furthermore, in order to speed up the measurement process of the backhaul device during the link measurement, the following information may be obtained when the emergency base station has a network connection:

[0342] 1) Obtaining (opposite end) satellite network related information, including but not limited to satellite ephemeris information, satellite beam information, satellite frequency information, etc., and storing it in the emergency base station; when the satellite device is triggered to perform measurement, informing the satellite device of the information via a wired manner (corresponding to the above-mentioned sending a link quality test indication to the satellite device according to the backhaul link priority information and the related information; the link quality test indication carries the related information).

[0343] Part 2, frequency coordination solution (the first network side device takes the emergency base station as an example, and the wireless backhaul device takes the CPE as an example):

[0344] If it is decided to use CPE for backhaul, frequency coordination needs to be automatically completed in order to avoid mutual interference between the backhaul link and the emergency base station wireless coverage link.

[0345] 1) Pre-store the available frequencies and bandwidth information (corresponding to the above-mentioned total bandwidth resources) corresponding to the emergency base station and the CPE in the emergency base station;

[0346] 2) The CPE automatically searches for signals from surrounding cells, and records the cell ID, cell frequency band (corresponding to the first frequency), cell bandwidth (corresponding to the first bandwidth) and other information corresponding to each cell, and transmits it back to the emergency base station;

[0347] 3) The emergency base station determines the backhaul frequency, backhaul bandwidth, emergency base station coverage frequency (corresponding to the above base station coverage frequency) and emergency base station coverage bandwidth (corresponding to the above base station coverage bandwidth) and the adopted frame structure configuration (corresponding to the frame structure used for the above information transmission) according to the available frequency and bandwidth information, the received cell frequency band and cell bandwidth, and the coverage requirements (corresponding to the above coverage requirement information);

[0348] 4) Determine the bandwidth size of the two according to the backhaul bandwidth requirements and the emergency base station coverage bandwidth requirements. If the emergency base station coverage requires the division of cells (for example, two cells, the public network and the private network, and different cells need to access different core networks), the available bandwidth resources of the emergency base station coverage can be allocated in proportion to the bandwidth requirements of the two cells to avoid interference;

[0349] 5) If the backhaul frequency (and backhaul bandwidth) or the emergency base station coverage frequency (and emergency base station coverage bandwidth) cannot meet the business demand (corresponding to the above business demand condition) or the preset rate requirement (corresponding to the above preset rate condition), the public network base station (corresponding to the above second base station) may be temporarily shut down or the cell bandwidth of some public network base stations may be adjusted (corresponding to the above sending frequency bandwidth adjustment information to the second base station when the fifth preset condition is not met) in at least one of the following ways:

[0350] a) The interface between the emergency base station and the network management informs the network management, and the network management informs the public network base station that needs to be adjusted (corresponding to the above-mentioned sending of the frequency bandwidth adjustment information to the network management device, and sending it to the second base station through the network management device);

[0351] b) The emergency base station notifies the public network base station that needs to be adjusted through the Xn or X2 interface between base stations (corresponding to directly sending the frequency bandwidth adjustment information to the second base station above);

[0352] c) The emergency base station sends the frequency bandwidth adjustment information to the CPE, and the CPE sends the frequency bandwidth adjustment information to the second base station:

[0353] a1) The CPE reports to the public network base station connected to the CPE (i.e., the base station corresponding to the cell accessed by the CPE, which is one of the second base stations) or the core network through RRC information or NAS information, and informs the network management through other base stations or the interface between the core network and the network management, and informs the public network base station that needs to be adjusted through the network management (corresponding to the above-mentioned sending of the frequency bandwidth adjustment information to the second network side device through radio resource control RRC signaling or non-access layer NAS signaling, and forwarding by the second network side device to the second base station through the network management device);

[0354] a2) The CPE reports to the public network base station connected to the CPE through an RRC message, and notifies other public network base stations that need to be adjusted through the Xn or X2 interface between base stations (corresponding to the above-mentioned sending of the frequency bandwidth adjustment information to the second network side device through RRC signaling, and the second network side device directly sending it to the second base station); other public network base stations are public network base stations other than the public network base station connected to the CPE;

[0355] a3) CPE reports to the frequency control platform through an application layer message, and informs the public network base station that needs to be adjusted through the frequency control platform (corresponding to the above-mentioned sending of the frequency bandwidth adjustment information to the second network side device through application layer signaling, and the second network side device directly sending it to the second base station).

[0356] It is noted here that when the backhaul device is not a CPE, the coverage frequency and coverage bandwidth of the emergency base station can also be determined according to the requirements of the public and private networks, which will not be repeated here.

[0357] The following is a specific example of the solution provided by the embodiment of the present invention.

[0358] Example 1:

[0359] If CPE backhaul is used, the automatic frequency coordination process can be as follows:

[0360] 1) Pre-store available frequencies and corresponding bandwidth information in the emergency base station, assuming: 2.6G 160M bandwidth, 4.9G 100M bandwidth, 700M 2×30M bandwidth;

[0361] 2) The CPE automatically searches for signals from surrounding cells, and records the cell ID, cell frequency band, cell bandwidth and other information corresponding to each cell and transmits it back to the emergency base station: Assume that the frequency band searched by the CPE is 2.6G 2515-2615M bandwidth and 2.6G 2615-2675M bandwidth;

[0362] 3) The emergency base station determines the backhaul frequency, backhaul bandwidth, emergency base station coverage frequency, application base station coverage bandwidth and the adopted frame structure configuration according to the available frequency and bandwidth information, the searched cell frequency band and cell bandwidth, and the coverage requirements: If the emergency base station has high requirements for both coverage and rate, the emergency base station uses 700M and 4.9G 1D3U (frame structure) at the same time;

[0363] 4) Determine the bandwidth size of the two according to the backhaul bandwidth requirements and the emergency base station coverage bandwidth requirements: Since the higher the backhaul rate, the better, the backhaul uses 2.6G 160M cell, and the emergency base station coverage uses 700M 2×30 and 4.9G 100M. If the emergency base station coverage has the need to divide the cells (different cells access different core networks), the above bandwidth resources can be allocated proportionally according to the bandwidth requirements of the two cells (that is, the available bandwidth resources for emergency base station coverage).

[0364] Example 2:

[0365] If CPE backhaul is used, the automatic frequency coordination process can be as follows:

[0366] 1) Pre-store available frequencies and corresponding bandwidth information in the emergency base station, assuming: 2.6G 160M bandwidth, 4.9G 100M bandwidth, 700M 2×30M bandwidth;

[0367] 2) The CPE automatically searches for signals from surrounding cells, and records the cell ID, cell frequency band, cell bandwidth and other information corresponding to each cell and transmits it back to the emergency base station: Assume that the frequency bands searched by the CPE are 2.6G 2515-2615M bandwidth, 2.6G 2615-2675M bandwidth, and 4.9G 4800-4900M bandwidth;

[0368] 3) The emergency base station determines the backhaul frequency, backhaul bandwidth, emergency base station coverage frequency and application base station coverage bandwidth and the adopted frame structure configuration according to the available frequency and bandwidth information, the searched cell frequency band and cell bandwidth, and the coverage requirements: In order to avoid interference problems, the emergency base station can use the frequency of 700M FDD (frame structure);

[0369] 4) Determine the bandwidth size of the two according to the backhaul bandwidth requirements and the emergency base station coverage bandwidth requirements: Since some cells have the same bandwidth, the cell is determined based on the channel quality measured by the CPE. If the 4.9G signal is better at this time, the backhaul uses the 4.9G 100M cell and the emergency base station coverage uses 700M 2×30M;

[0370] 5) Assuming that the 60M frequency bandwidth covered by the emergency base station cannot meet the business needs or the preset rate requirements at this time, the required bandwidth can be calculated (for example, 60M spectrum is still required), and the adjustment requirements can be reported to the frequency control platform through the CPE application layer message. The public network base station that needs to be adjusted is informed through the frequency control platform to free up 2.6G 60M bandwidth, that is, temporarily close the surrounding 2.6G2615M-2575M cells (any 2.6G of the above bandwidth is sufficient).

[0371] As can be seen from the above, the solution provided by the embodiment of the present invention involves:

[0372] (1) Adaptively select the backhaul link based on factors such as service type, backhaul link quality, and cost.

[0373] (2) When the emergency base station moves, causing the quality of the backhaul link to change or be interrupted, the emergency base station triggers the switching of the backhaul link and performs the backhaul link measurement, adaptive selection, and automatic establishment process.

[0374] (3) Based on the available frequency and total bandwidth resources, as well as the signals searched by the CPE and the corresponding frequency and bandwidth information, the CPE autonomously determines the backhaul frequency and backhaul bandwidth as well as the emergency base station coverage frequency and emergency base station coverage bandwidth, and automatically completes the frequency coordination process.

[0375] In summary, this solution has the following advantages compared with the prior art:

[0376] (1) Without manual intervention, the automatic link adaptation selection process can be completed based on factors such as service type, link quality, and cost to ensure service experience.

[0377] (2) The solution can realize the automatic switching capability of the backhaul link based on performance.

[0378] (3) The solution can realize automatic frequency allocation and coordination, avoiding mutual interference between backhaul links and coverage links, while meeting business needs.
