The user terminal UE according to the embodiments of the present invention may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. Wireless user terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), and may exchange language and/or data with the RAN. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless User Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access Point (Access Point), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a User Device.
A base station according to embodiments of the present invention may be configured to interconvert received air frames and IP packets as a router between a wireless terminal device and a remainder of an access network, where the remainder of the access network may include an Internet Protocol (IP) network device. The base station may also coordinate management of attributes for the air interface. For example, the Base Station may be a network device in a 5G System, such as a Next generation Base Station (gNB), a Base Transceiver Station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB) in a Wideband Code Division Multiple Access (WCDMA), or an evolved Node B (eNB) in LTE, which is not limited in the embodiments of the present invention.
At present, the base station generally adopts a mode of setting default values for configuring switching parameters, but the mode is difficult to be applied to all scenes, and switching fault events are easily caused. The prior art has the problem of poor switching parameter configuration effect.
For some special scenes and areas, a network engineer can judge manually and reasonably adjust or configure switching parameters by combining information such as telephone traffic, user quantity and the like. Although the method for manually adjusting the switching parameters can play a role in optimization, more human resources are occupied, and the efficiency is low; secondly, the configuration effect completely depends on the optimization experience of network engineers, and the adjustment methods of different engineers are different, so that the unified standard cannot be researched; in addition, due to the complexity of the geographic environment and the network structure, the manual configuration method is often not considered thoroughly, and therefore the effect is not good.
In addition, based on the Auto Neighbor Relation (ANR), the base station can implement the automatic rational configuration of the Neighbor by the base station, improve the efficiency and accuracy of the Neighbor configuration, and optimize the Neighbor in the LTE system and between the LTE and GSM systems. However, ANR can only be optimized for a neighboring cell, and a method of configuring a default value is still used for a handover parameter for controlling handover of the neighboring cell, so the effect of configuring the handover parameter is still poor.
In order to solve the technical defects in the prior art, embodiments of the present invention provide a method for configuring a handover parameter. The method may be executed by a device configured to switch parameters, where the device may be located in a base station, or may be the base station, or other network equipment with a function similar to that of the base station, and the embodiment of the present invention is not limited in particular. Referring to fig. 1, the method includes:
step 101: and obtaining the measurement information of the measurement cell reported by all the UE under the base station.
Specifically, the base station collects measurement information of the local Cell and all neighboring cells reported by all UEs in the local Cell, where the measurement information specifically includes physical-layer Cell identity (PCI), network type, frequency point, and level value of the frequency point.
Step 102: and determining the priority relation between the cell where the base station is located and the adjacent cell according to the measurement information.
In a specific implementation process, the number of the neighboring cells of one base station may be one, or may be multiple, and the embodiment of the present invention is not limited specifically. Step 101, when the number of the neighboring cells of the base station is determined to be multiple, the method for the base station to determine the priority relationship between the cell where the base station is located and each neighboring cell is the same, taking one neighboring cell of the base station as an example: firstly, judging whether the network type of a cell where a base station is located is the same as the network type of an adjacent cell; if the network types are different, the priority relation between the cell in which the base station is positioned and the adjacent cell can be determined directly according to the network type of the cell in which the base station is positioned and the level of the network type of the adjacent cell; if the cell priority relationship is the same as the cell priority relationship, calculating a characteristic value representing the priority relationship between the cell and the adjacent cell according to the frequency point and level value of the cell in which the base station is located and the frequency point and level value of the adjacent cell, and then determining the priority relationship between the cell in which the base station is located and the adjacent cell according to the value range of the characteristic value.
When the network type of the cell where the base station is located is the same as the network type of the neighboring cell, calculating a characteristic value representing the priority relationship between the cell where the base station is located and the neighboring cell based on the following formula:
in the formula, in the above-mentioned formula,
in order to represent a characteristic value of the priority relationship between a cell where the base station is located and the adjacent cell, f0 is a frequency point of the cell where the base station is located reported by all UE under the base station, fn is a frequency point of the adjacent cell reported by all UE under the base station, P0 is an average value of level values of the cell where the base station is located reported by all UE under the base station, Pn is an average value of level values of the adjacent cell reported by all UE under the base station, and theta is a preset value;
correspondingly, determining the priority relationship between the cell where the base station is located and the neighboring cell according to the value range of the characteristic value includes: in determining
Then, determining that the priority of the cell where the base station is located is lower than the priority of the neighbor cell; in determining
Then, determining that the priority of the cell where the base station is located is the same as the priority of the adjacent cell; in determining
And then, determining that the priority of the cell in which the base station is positioned is higher than that of the neighbor cell.
For example, the cell in which the base station is located is cell a, and the neighboring cell is cell b. The network standard of the cell a is a GSM network, the network of the cell b is an LTE network, and the grade of the LTE network is higher than that of the GSM network, so that the priority of the cell a can be directly determined to be lower than that of the cell b.
For example, let θ be 1/80, the cell in which the cell base station is located is cell c, and the neighboring cell is cell d. Wherein, the network systems of the cell c and the cell d are both LTE networks, the frequency point of the cell c is 1900MHz, the level value is-80 dBm, the frequency point of the cell d is 2350MHz, the level value is-87 dBm, and then
The priority of cell c is lower than the priority of cell d.
Step 103: and configuring a switching parameter for controlling the UE to be switched from the cell where the base station is located to the adjacent cell according to the priority relation.
Corresponding to step 102, when the network type of the cell where the base station is located is different from the network type of the neighboring cell, configuring a handover parameter for controlling the UE to handover from the cell where the base station is located to the neighboring cell according to the priority relationship, including:
when the priority of the cell where the base station is located is lower than that of the adjacent cell, the switching parameter is configured to be a null value, so that when the base station receives a cell switching request sent by any UE under the base station, the base station responds to the cell switching request and switches any UE from the cell where the base station is located to the adjacent cell.
For example, the cell in which the base station is located is cell a, the neighboring cells have b1 and b2, and assuming that the priority of cell a (3G network) is higher than that of cell b2(2G network) and lower than that of cell b2(LTE network), the base station can immediately respond to the cell handover request when receiving the cell handover request sent by a certain UE (the current serving cell of the UE is a) under the base station, and handover the serving cell of the UE from a to b 2.
Corresponding to step 102, when the network type of the cell where the base station is located is the same as the network type of the neighboring cell, configuring a handover parameter for controlling the UE to handover from the cell where the base station is located to the neighboring cell according to the priority relationship, including:
according to the measurement information of the cell where the base station is located and each adjacent cell collected in the step 101 and the priority relation determined in the step 102, the switching parameters from the cell where the base station is located to each adjacent cell are calculated, and the calculation output result is R (A)k，EΔ) Wherein A iskRepresenting a handover event (strategy), the value range of k is 3, 4 and 5, which respectively represent A in the LTE network3，A4，A5Three handover strategies, EΔ1，EΔ2Representing a handover parameter threshold. Wherein E isΔAnd the value of (1) and the value of (102)
It is related.
Setting the priority of the local cell in which the base station is positioned as C0The priority of the configurable adjacent area is CnThen the configuration of the handover parameters includes at least the following three cases:
1) when C is present0＝CnWhen k is 3, EΔ＝τ1dB, when P'n-P′0≥EΔWhen so, handover is performed.
Wherein, P'nLevel value P 'of adjacent cell reported by UE for sending cell switching request to base station'0Level value of cell in which base station is located, reported to UE sending cell switching request to base station, EΔ＝τ1dB，τ1Is a preset value, for example 3 or 5.
That is, the base station determines P 'when receiving a cell handover request transmitted by any UE under the base station'n-P′0≥EΔWhen the UE is switched to the adjacent cell from the cell where the base station is located in response to the cell switching requestAnd (4) a zone.
2) When C is present0＜CnWhen the number k is 4,
when P'n＞P′0+EΔWhen so, handover is performed.

And after calculating the switching parameters from the cell where the base station is located to the adjacent cell, adding the switching parameters corresponding to the adjacent cell into the base station.
It should be noted that, in the above steps 102 and 103, the method according to the embodiment of the present invention is mainly described by taking only one neighboring cell of the base station as an example. In a specific implementation process, when the base station has a plurality of neighboring cells, the above operation steps may be performed for each neighboring cell, so as to complete configuration of the handover parameters between the cell where the base station is located and all neighboring cells.
In the above scheme, the base station determines the priority relationship between the cell in which the base station is located and the neighboring cell through a large amount of measurement information of the cell in which the base station is located and the neighboring cell collected by the UE, and then configures the handover parameters from the cell in which the base station is located to the neighboring cell according to the priority relationship. Because the priority relation is determined by the measurement parameters of the cell where the base station is located and the adjacent cell, the technical effect of dynamically configuring the switching parameters aiming at different adjacent cell switching scenes can be realized, the accuracy of configuring the switching parameters is improved, the service perception of the UE in a mobile state is improved, and better communication service experience is provided for users; in addition, the scheme does not need manual configuration, so that a large amount of labor cost is saved, and the configuration efficiency is improved.
Optionally, before determining the priority relationship between the cell where the base station is located and the neighboring cell, the method may further include: and determining that the average value of the level values of the adjacent cells reported by all the UE under the base station is greater than a preset level value.
In a specific implementation process, the measurement parameters collected in step 101 may include measurement parameters of a plurality of neighboring cells, and a cell configurable for neighboring cell configuration may be determined from all measured neighboring cells, so that in the process of performing steps 102 and 103, only the determined configurable neighboring cell is configured with a handover parameter.
The specific implementation mode is as follows: setting the preset level value to GmIn units of decibel-milliwatt dBm, where GmM in (2) is used to distinguish different network systems. For any adjacent cell whether meeting the configurable adjacent cell condition, all UE in the cell of the base stationMeasuring the average value of the levels of any adjacent cells
Determine when
Greater than GmIf so, the neighbor cell can be determined to be a configurable neighbor cell, otherwise, the neighbor cell is a non-configurable neighbor cell. Wherein, G corresponding to different network systemsmThe value of (c) is different.
By the method, the configuration of the switching parameters can be realized only for the adjacent cell with good network quality, the configuration effect is further improved, and the service perception of the UE in a mobile state is improved.
Optionally, in a specific implementation process, a requirement of the UE using the data service for network coverage is different from a requirement of the UE using the voice service for network coverage, and generally, the requirement of the voice service for network coverage is higher than that of the data service. In view of this, when the above step 102 is executed, different priority determination criteria may be set for voice traffic and data traffic. The specific implementation mode is as follows:
1) data service:
because the data volume of the data service is large and the requirement on the download rate is high, the portable data volume is large in the signal of the high-frequency band cell, the high-frequency band interference is relatively small, and the data download rate is high, the high-frequency band cell should be preferentially occupied when the coverage strength of the high-frequency and low-frequency signals is not greatly different. According to experience, when the coverage intensity of the D-band cell is about 10dB higher than that of the F-band cell, the data service download rates of the two cells are basically equivalent, and at this time, the priorities of the two cells can be considered to be the same, so that the priority of the two cells is considered to be the same, and thus, the data service download method is applicable to the data service download system
In a corresponding manner, the first and second optical fibers are,
of course, in the specific implementation process, the value of θ may also be adjusted according to the actual situation, and the embodiment of the present invention applies the value of θAnd is not particularly limited. For example, in a province, because of more mountainous areas, the occlusion is serious, and when the coverage intensity of the D band is 5dB higher than that of the F band, the priority is regarded as the same, then in the province, the coverage intensity of the D band is regarded as the same as that of the F band
2) Voice service:
the voice service data volume is small, the requirement on the download rate is low, but the reliable transmission of the voice service data is ensured, so the requirement on the coverage level is high, the coverage distance and the penetrating performance of the low-frequency band signal are better than those of the high-frequency band signal, and therefore when the UE carries out the voice service, the UE should preferentially occupy the low-frequency band cell. According to experience, when the coverage levels of the F-band cell and the D-band cell are the same, the Mean Opinion Score (MOS) of the two cells is basically equivalent, and since the coverage performance of the F-band cell is better, when the level of the F-band cell is lower than 2dB of the D-band cell, the priority of the two cells can be considered to be the same,
in a corresponding manner, the first and second optical fibers are,
therefore, when the coverage strength of the F frequency band is enhanced, the cell switching frequency of the UE is reduced, and the problem of voice quality reduction caused by frequent switching is avoided. Of course, in the specific implementation process, the value of θ may also be adjusted according to the actual situation, and the value of θ is not specifically limited in the embodiment of the present invention.
Correspondingly, when the step 103 is executed, two sets of handover parameters may be configured for the same neighboring cell by using two different θ, where one is used to control the UE carrying the data service to perform handover from the cell where the base station is located to the neighboring cell, and the other is used to control the UE carrying the voice service to perform handover from the cell where the base station is located to the neighboring cell. When any UE under the base station sends a cell handover request, the service type carried by the UE may be determined according to the information of the scale value (QoS Class Identifier, QCI) of the UE, and then the corresponding handover parameter is selected for the UE. For example, QCI1 and QCI2 correspond to handover parameters of voice services, and QCI6, QCI7, QCI8 and QCI9 correspond to handover parameters of data services.
In the specific implementation process, based on the QCI level information, the service types can be layered more finely. For example, currently, QCI1 includes only voice, and QCI2 includes both video and voice, so different θ values can be set for QCI1 and QCI2, respectively. Similarly, the data services can be finely divided according to QCI6, QCI7, QCI8 and QCI9, for example, different QCI levels can be allocated to various service types such as real-time games, network videos, file downloads and the like, so that different θ values can be set for different data services.
By the method, different switching parameters can be configured for the UE with different service bearing types aiming at the same adjacent cell switching scene, so that the accuracy of configuring the switching parameters is further improved, and the service perception of the UE in a mobile state is improved.
Optionally, in a specific implementation process, in addition to the priority determination of the cell where the base station is located and the neighboring cells, the priority ranking of each neighboring cell of the base station may also be performed. When a base station receives a cell switching request sent by UE, if at least two adjacent cells meet the constraint conditions corresponding to the switching parameters according to the switching parameters corresponding to the adjacent cells, the base station can preferentially switch a service cell of the UE to a cell with a higher priority in the at least two adjacent cells. The method for determining the priority relationship between the neighboring cells may refer to the method for determining the priority relationship between the cell where the base station is located and the neighboring cell in step 102, which is not described in detail in the embodiments of the present invention.
By the method, the accuracy of configuring the switching parameters can be further improved, and the service perception of the UE in the mobile state is improved.
