The NSA mode is a mode in which a terminal having an NSA dual connection capability is connected to a 4G base station and a 5G base station and transmits using radio resources of both base stations. In the dual-connection scenario, the UE may be connected to the 4G base station and the 5G base station at the same time, where one serves as a master base station and the other serves as a slave base station. The judgment of the master base station and the slave base station depends on the anchor point of the control plane, and the base station with the control plane following the core network is the master base station, namely the 4G base station is the master base station, and the 5G base station is the slave base station. The main base station carries out anchor point with FDD1800 frequency channel, however, present net FDD1800 frequency channel does not form continuous coverage, and the capacity is restricted, and NSA construction synchronization is opened FDD1800 frequency channel and is costlier.
In order to accelerate the construction of 5G and quickly form 5G capability, embodiments of the present invention provide an anchor selection method, apparatus, device, and computer-readable storage medium based on NSA mode, which can simultaneously anchor multiple frequency bands based on a primary base station, and avoid the defect that an anchor cell cannot be accessed due to weak coverage, high load, and other problems.
The following describes an anchor point selection method based on NSA mode according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart of an anchor point selection method based on an NSA mode according to an embodiment of the present invention. As shown in fig. 1, the NSA mode-based anchor selection method 100 may include S110 to S130.
S110, a first manufacturer identification of the first equipment, a second manufacturer identification of the second equipment and a third manufacturer identification of the third equipment of the slave base station of the master base station are obtained.
The master base station is a 4G base station, the slave base station is a 5G base station, the first equipment is equipment for communicating with the UE at a first frequency band by the master base station, the second equipment is equipment for communicating with the UE at a second frequency band by the master base station, and the third equipment is equipment for communicating with the UE in the slave base station. The first frequency band and the second frequency band may be any frequency band of the 4G frequency bands. For example, the first frequency band is an FDD1800 frequency band, and the second frequency band is an F frequency band.
And S120, when the first manufacturer identification is consistent with the third manufacturer identification, determining whether the first frequency band continuously covers the target area.
Specifically, the first vendor identifier and the third vendor identifier are compared, and when the first vendor identifier and the third vendor identifier are identical, it indicates that the first device and the third device are produced by the same vendor, and the vendor identifier may be an identifier of a production mechanism of the device. Next, it is determined whether the first band continuously covers a target area in which the main base station is located. The target area may be an area to be established that supports access to the 5G service, for example, the target area may be a residential area, a school, a train station, an airport, or the like. Alternatively, whether the first frequency band continuously covers the target area may be determined according to the site construction density of the base stations using the first frequency band in the target area.
And S130, when the first frequency band does not continuously cover the target area and the second manufacturer identification is consistent with the third manufacturer identification, the main base station uses the first frequency band and the second frequency band to carry out anchor point.
Specifically, when it is determined that the first frequency band does not continuously cover the target area, the second vendor identifier and the third vendor identifier are compared, and when the second vendor identifier and the third vendor identifier are consistent, it is determined that the second device and the third device are produced by the same vendor. At this time, anchor priorities of the first frequency band and the second frequency band may be set, wherein the anchor priority of the first frequency band is greater than the anchor priority of the second frequency band, and the anchor is jointly anchored based on the anchor priority of the first frequency band and the anchor priority of the second frequency band.
Otherwise, when it is determined that the first frequency band continuously covers the target area, the master base station may perform anchor using the first frequency band.
According to the anchor selection method based on the NSA mode, the device used by the main base station for carrying out 4G communication with the UE and the device used by the slave base station for carrying out 5G communication with the UE belong to the same manufacturer, and therefore the anchor points are simultaneously anchored on the basis of the multiple frequency bands of the main base station, the problems caused by the coverage and capacity of the anchor point of a single frequency band are solved, the defect that an anchor point cell cannot be accessed due to the problems of weak coverage, high load and the like is overcome, the construction of 5G can be accelerated, and the 5G capacity can be quickly formed.
In some embodiments, when the first vendor identifier is not consistent with the third vendor identifier, it indicates that the first device and the third device are not manufactured by the same vendor, and then it is determined whether the second frequency band continuously covers the target area. Alternatively, whether the first frequency band continuously covers the target area may be determined according to the site construction density of the base stations using the second frequency band in the target area.
When the second frequency band is determined to continuously cover the target area, the second manufacturer identification is compared with the third manufacturer identification, and when the second manufacturer identification and the third manufacturer identification are consistent, the main base station can use the second frequency band to perform anchor point.
On the contrary, when the second frequency band does not continuously cover the target area, the fourth vendor identifier of the fourth device of the master base station is obtained, wherein the fourth device is a device of the master base station communicating with the UE in the third frequency band. The third frequency band may be any frequency band in the 4G frequency band, for example, the third frequency band is a D frequency band or an FDD900 frequency band. And when the fourth manufacturer identifier is consistent with the third manufacturer identifier, the fourth device and the third device are produced by the same manufacturer. At this time, the main base station performs anchor using the third frequency band.
A specific example is described below as to how the main base station uses the second frequency band for anchor point, where the first frequency band is FDD1800, and the second frequency band is an F frequency band, specifically as follows:
firstly, an X2 interface, namely X2-C, X2-U, between a master base station and a slave base station is established, and data shunting is realized through the X2 interface. Next, the primary base station configures a Primary Carrier Component (PCC) frequency point, that is, an anchor point of the NSA, and the primary base station is configured with an F band 38400. Next, the primary base station performs Secondary Cell Group (SCG) and Synchronization Signal Block (SSB) frequency point allocation, and adds an NR external Cell, an NR adjacent frequency point, and an adjacent relationship. In addition, the master base station and the slave base station need to open a Dual Connectivity (DC) switch, NR cell NSA-DC parameter configuration, and configure a QoS Class Identifier (QCI) bearer for the NR cell. And testing after the main base station and the slave base station are configured, wherein the cell initial access occupies 38400 frequency points to perform anchor point, and the slave base station is added. The steps of using anchor points of other frequency bands by the main base station are similar, and for brevity, are not described herein again.
In some embodiments, after the main base station performs the anchor point by using the first frequency band and the second frequency band, when the capacities of the first frequency band and the second frequency band of the main base station exceed the preset threshold and/or the second frequency band does not continuously cover the target area, the fourth manufacturer identifier of the fourth device of the main base station is obtained, and when the fourth manufacturer identifier is consistent with the third manufacturer identifier, the main base station may perform the anchor point by using the first frequency band, the second frequency band, and the third frequency band. Specifically, anchor priority may be set for a first frequency band, a second frequency band, and a third frequency band, where the anchor priority of the first frequency band is greater than the anchor priority of the second frequency band, the anchor priority of the second frequency band is greater than the anchor priority of the third frequency band, and the anchor is associated based on the anchor priority of the first frequency band, the anchor priority of the second frequency band, and the anchor priority of the third frequency band.
When the UE accesses the anchor cell, it may be detected whether the anchor priority of the anchor cell is the highest. And when detecting that the anchor priority of the anchor cell is not the highest, accessing the UE to the adjacent anchor cell with the highest anchor priority. When the priority of the anchor point cell occupied by the UE is low, the UE can be quickly switched to the adjacent anchor point cell with the highest anchor point priority.
In a specific example, whether the anchor priority of an anchor cell accessed by the UE is the highest is detected, when the anchor priority is not the highest, the anchor base station issues an A5 measurement to the UE, and the UE receives an A5 measurement and uploads an A5 measurement report to the anchor base station. And determining whether the signal quality of the anchor point cell and the signal quality of the adjacent anchor point cell meet a switching threshold according to the A5 measurement report, and switching the UE to the adjacent anchor point cell with the highest anchor point priority when the signal quality of the anchor point cell and the signal quality of the adjacent anchor point cell meet the switching threshold.
Aiming at the existing network, the number of anchor point terminals supporting FDD1800 is more, and in order to ensure the use and perception of a user 5G, the terminal supporting multiple anchor points can preferentially occupy the FDD1800 frequency band as an anchor point and is switched to other 4G frequency bands, such as an F frequency band, based on coverage.
In a specific example, the first frequency band is FDD1800, the second frequency band is an F frequency band, a first vendor identifier of a device of the master base station communicating with the UE in the FDD1800 frequency band, a second vendor identifier of a device communicating with the UE in the F frequency band, and a third vendor identifier of a third device of the slave base station are obtained. And when the first manufacturer identification is consistent with the third manufacturer identification, determining whether the FDD1800 frequency band continuously covers the target area. And when the FDD1800 frequency band does not continuously cover the target area and the second vendor identifier is consistent with the third vendor identifier, the main base station configures the FDD1800 frequency band and the F frequency band as NSA anchor points respectively. FDD1800 anchor priority is configured to be 7, F frequency band anchor priority is configured to be 6, the rest non-anchor frequency bands are all set to be 0, and UE can preferentially establish double connection with NR in an FDD1800 anchor cell. In an area where the FDD1800 signal is weak, for example, the FDD1800 frequency band signal is lower than a preset signal threshold, an a5 measurement may be issued, and the frequency band may be switched to the F frequency band for the anchor point. It can be understood that other 4G frequency band joint anchor points can be introduced similarly.
It should be noted that, if the network load of the anchor point cell exceeds the preset load threshold, load balancing is performed on the terminal that does not support NSA, the terminal that supports NSA is reserved, and the user experience of the 5G user is improved.
