Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and particularly to a method and apparatus for adding a secondary base station. Background Art

[0002] In an NSA network deployment, 5G base stations need to deploy the anchor station at an LTE site. When adding an SCG (Secondary Cell Group) to the anchor station, it is particularly important to determine which SCG to add, which directly affects the user experience. Also, since many NSA terminal users conduct services while moving, there will be continuous handovers between multiple cells during the movement. Selecting which SCG to add during the continuous handover process at the anchor station to enable the user to add the SCG site most smoothly becomes a key issue.

[0003] The existing methods for adding a secondary base station mainly include the following two types:

[0004] One is the method for adding a secondary base station based on the strongest measured signal level, which mainly makes a judgment according to the neighbor-level signal level reported by the user and selects the cell with the strongest signal level as the secondary base station. This method has certain deficiencies and limitations. During the process of adding a secondary base station, only the signal level value is considered, and the signal level value cannot reflect the most reasonable cell in the user's traveling direction. The strongest signal level may not be the most reasonable cell during the movement of NSA terminal users. Therefore, it will cause the addition of redundant secondary base stations, increasing unnecessary handovers and signaling overhead.

[0005] One is the method for adding a secondary base station based on the co-covered cells of the local station, which mainly adds a secondary base station based on the anchor station occupied by the NSA terminal user and according to the sectors co-covered by the anchor station. This method has certain deficiencies and limitations. Since the user is moving, the co-covered station may not be the most reasonable cell in the traveling direction. After adding it, the secondary base station needs to be deleted and re-selected during subsequent service operations, resulting in many redundant additions of secondary base stations and affecting the user experience.

[0029] In a second aspect, the present invention provides a device for adding a secondary base station, including: a first sorting module, a first determination module, and a first secondary base station addition execution module.

[0050] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0051] The terminal involved in the embodiments of the present application can be a device that provides voice and / or data connectivity to users, such as a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called a user equipment (UE).

[0052] The network device involved in the embodiments of the present application can be a base station, which can include multiple cells that provide services to terminals. Depending on the specific application scenario, the base station can also be called an access point, or it can be a device in the access network that communicates with wireless terminal devices through one or more sectors over the air interface, or other names.

[0053] Figure 1 is one of the schematic flowcharts of the method for adding a secondary base station provided by the present invention. Refer to Figure 1 , the method for adding a secondary base station provided by the present invention may include:

[0054] S110. Sort the first probabilities in descending order;

[0055] S120. Sequentially judge the preset conditions for each first cell corresponding to each first probability until a first cell that meets the preset conditions is determined;

[0056] S130. Use the base station of the first cell that meets the preset conditions as the secondary base station;

[0057] Among them, the first probability is the probability that the terminal performs continuous cell handover, and the first probability is greater than or equal to the probability threshold;

[0058] The preset condition is a 5G site with a co-site;

[0059] The terminal's continuous cell handover includes: the terminal hands over from the target cell to the first cell, and then from the first cell to the second cell.

[0060] It should be noted that the execution entity of the method for adding a secondary base station provided by the present invention can be a network-side device, such as a base station, etc. Specifically, it can be the network-side device corresponding to the target cell.

[0061] Specifically, in step S110, the first probabilities are sorted in descending order. The first probability is the probability that the terminal performs continuous cell handover. The terminal performing continuous cell handover means that the terminal switches from the target cell m to the first cell s, and then from the first cell s to the second cell j, that is, the terminal switches twice within the cell. The larger the value of the first probability, the greater the probability that the terminal performs continuous cell handover. A probability threshold P is preset. When the first probability is greater than or equal to the probability threshold P, it is determined that the terminal performs continuous cell handover. A continuous cell handover discriminator can be set to determine whether the cell belongs to continuous handover according to the handover probability, that is, the judgment of the continuous cell handover probability. All the first probabilities greater than or equal to the probability threshold P are sorted in descending order.

[0062] In one embodiment, the value range of the probability threshold P is 0.5 to 1. Of course, its specific value can also be adjusted according to actual needs, and the present invention does not limit this.

[0063] Specifically, in step S120, preset condition judgment is sequentially performed on the first cells corresponding to the first probabilities until the first cell s that meets the preset conditions is determined. After sorting all the first probabilities greater than or equal to the probability threshold P in descending order, the preset condition judgment is sequentially performed on the first cell s corresponding to the first probabilities in the order from large to small of the values of the first probabilities, that is, it is sequentially judged whether the first cell s has a co-located 5G site. If the first cell s corresponding to the maximum value of the first probability does not have a co-located 5G site, then continue to judge whether the first cell s corresponding to the second largest value of the first probability has a co-located 5G site, and so on, continue to judge until the first cell s corresponding to the first probability has a co-located 5G site. A cell co-located 5G discriminator can be set to judge whether there is a co-located 5G site for the anchor station. It can be defined that the 5G site SgNB co-located with cell i is SgNB i ,

[0064] SgNB i ∈{0,1}

[0065] Where: SgNB i = 1 indicates that there is a co-located 5G site for cell i.

[0066] Specifically, in step S130, the base station of the first cell that meets the preset conditions is used as the secondary base station, that is, the first cell s corresponding to the first probability has a co-located 5G site, SgNB s= 1, the 5G site of this cell is the site in the direction of travel. When the terminal performs continuous cell handover, it hands over from the target cell m to the first cell s, and then from the first cell s to the second cell j, adding the base station of the first cell s as the secondary base station. That is, although the terminal has performed two handovers, it only needs to add the secondary base station once. The user occupies the secondary base station for the longest time, reducing the inter-frequency measurement, reducing the rate loss, and adding the secondary base station in the direction of travel with the highest probability, reducing unnecessary handover times and signaling overhead, and ensuring the rapidity of adding the secondary base station. And it can efficiently and quickly reduce the load of the cell, increase the value of evenly distributing users to the target cell, ensure that the load of this cell can be quickly reduced after evenly distributing the user to the target cell under the movement handover of NSA terminal users, accurately reflect the actual quality of the target cell, ensure the user experience, and can avoid the impact of sudden and single scheduling on the system, ensure the stability of the target cell, and maximize the load balancing efficiency.

[0067] The method for adding a secondary base station provided by the present invention determines whether to add the base station of the first cell in the continuous handover process as the secondary base station by judging whether the preset conditions are met, which can ensure that in the continuous handover process, the secondary base station in the direction of travel is added with the highest probability, thereby reducing unnecessary handover times and signaling overhead, ensuring the rapidity of adding the secondary base station, making the user occupy the secondary base station for the longest time, reducing the inter-frequency measurement and reducing the rate loss.

[0068] Figure 2 It is the second flow schematic diagram of the method for adding a secondary base station provided by the present invention. Refer to Figure 2 , in the case where the preset conditions are judged for each first cell corresponding to the first probability in turn, but the first cell that meets the preset conditions has not been determined, the method for adding a secondary base station provided by the present invention may further include:

[0069] S210. Sort the second probabilities in descending order;

[0070] S220. Judge the preset conditions for each first cell corresponding to the second probability in turn until the first cell that meets the preset conditions is determined;

[0071] S230. Use the base station of the first cell that meets the preset conditions as the secondary base station;

[0072] Wherein, the second probability is the probability of the terminal performing a single cell handover;

[0073] The terminal performing a single cell handover includes: the terminal handing over from the target cell to the first cell.

[0074] Specifically, based on the above embodiments, if all the first cells corresponding to the first probabilities do not meet the preset conditions, that is, all the first cells corresponding to the first probabilities do not have co-located 5G stations, then step S210 is executed. In step S210, the second probabilities are sorted in descending order. The second probability is the probability of the terminal making a single cell handover. The terminal making a single cell handover means that the terminal switches from the target cell m to the first cell s, that is, the terminal makes one handover within the cell. All the second probabilities are sorted in descending order.

[0075] Specifically, in step S220, the preset conditions are sequentially judged for each first cell corresponding to the second probabilities until a first cell that meets the preset conditions is determined. After sorting all the second probabilities in descending order, the preset conditions are sequentially judged for the first cell s corresponding to the first probability in the order of decreasing values of the second probability, that is, it is judged whether the first cell s has a co-located 5G station. If the first cell s corresponding to the maximum value of the second probability does not have a co-located 5G station, then continue to judge whether the first cell s corresponding to the second largest value of the second probability has a co-located 5G station, and so on, continue to judge until the first cell s corresponding to the first probability has a co-located 5G station.

[0076] Specifically, in step S230, the base station of the first cell that meets the preset conditions is used as the secondary base station. That is, the first cell s corresponding to the second probability has a co-located 5G station, and the 5G station of this cell is the station in the traveling direction. The terminal makes a single cell handover, switches from the target cell m to the first cell s, and adds the base station of the first cell s as the secondary base station. The secondary base station in the traveling direction is added with the highest probability to ensure the smoothest addition of the secondary base station and the stability of the addition of the secondary base station. A maximum possible handover cell determiner can be set to calculate the judgment of the maximum possible handover cell in the case of non-consecutive handovers.

[0077] The method for adding a secondary base station provided by the present invention determines whether to add the base station of the first cell in the single handover process as the secondary base station by judging whether the preset conditions are met, which can ensure that in the single handover process, the secondary base station in the traveling direction is added with the highest probability, thereby ensuring the smoothest addition of the secondary base station and the stability of the addition of the secondary base station.

[0078] In one embodiment, determining the second probability that the terminal switches from the target cell to the first cell includes: collecting the first handover times of the terminal from the target cell to the first cell, and the second handover times of the terminal from the target cell to all neighboring cells, and the second probability is the ratio of the first handover times to the second handover times.

[0079] Specifically, a cell handover counter can be set to count the handover times information of all cell handover pairs.

[0080] For example, the first handover count of the collection terminal from the target cell m to the first cell s and the second handover count of the terminal from the target cell m to all M neighboring cells Then the second handover probability of the terminal from cell m to cell s is:

[0081]

[0082] In one embodiment, determining the third probability of the terminal from the first cell to the second cell includes: collecting the third handover count of the terminal from the first cell to the second cell, and the fourth handover count of the terminal from the first cell to all neighboring cells, and the third probability is the ratio of the third handover count to the fourth handover count.

[0083] For example, the third handover count of the collection terminal from the first cell s to the second cell j and the fourth handover count of the terminal from the first cell to all N neighboring cells Then the third handover probability of the terminal from cell s to cell j is:

[0084]

[0085] In one embodiment, the first probability is determined in the following manner: determining the second probability of the terminal from the target cell to the first cell; determining the third probability of the terminal from the first cell to the second cell; and the first probability is the product of the second probability and the third probability.

[0086] Specifically, the first probability is the probability that the terminal goes from the target cell m to the first cell s and then from the first cell s to the second cell j. According to the above formula (1), the second probability of the terminal from the target cell m to the first cell s can be determined According to the above formula (2), the third probability of the terminal from the target cell s to the first cell j can be determined Then the third probability that the terminal goes from the target cell m to the first cell s and then from the first cell s to the second cell j is:

[0087]

[0088] Next, the apparatus for adding a secondary base station provided by the present invention will be described. The apparatus for adding a secondary base station described below can be correspondingly referred to the method for adding a secondary base station described above.

The third probability is the ratio of the third number of handovers to the fourth number of handovers.
