Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The handover method provided by the embodiment of the present invention can be applied to a base station, wherein the base station can include various orders of mobile communication technology base stations, the orders are determined according to the development stages of mobile communication technologies, for example, the order corresponding to the second generation mobile communication technology (2G) is 2 orders, the order corresponding to the third generation mobile communication technology (3G) is 3 orders, the order corresponding to the fourth generation mobile communication technology (4G) is 4 orders, the order corresponding to the fifth generation mobile communication technology (5G) is 5 orders, and the like, and the mobile communication technologies with orders above the fifth generation can include 6G/7G, and the like. Each base station may include at least one cell, and each cell may be a serving cell of the terminal device or a target cell of the terminal device, where the serving cell is a cell providing service for the terminal device, and the target cell is a cell to which the terminal device is to be accessed. Two cells covered with overlapping and set with switching relation can be adjacent cells (adjacent cells), and one cell can comprise a plurality of adjacent cells; the adjacent area has the following functions: the mobile phone can smoothly alternate services among a plurality of cells with defined adjacent cell relations in a mobile state without interruption.
After determining the target cell, the base station of the serving cell sends a switching request to the base station of the target cell to judge whether the target cell allows the terminal device to access; when the target cell does not allow to access the terminal equipment, a rejection message is returned, and after receiving the rejection message, the base station of the serving cell does not send a corresponding instruction to the terminal equipment, namely, the terminal equipment cannot take the target cell as the serving cell; and further causes the waste of corresponding resources of the base station and reduces the switching efficiency of the terminal equipment. Therefore, an embodiment of the present invention provides a handover method, that is, after configuring access conditions of a cell, a corresponding cell change attribute may be configured for the neighboring cell in a neighboring cell relation table according to configuration information of the neighboring cell; and then can judge whether to send the district change request to the base station of the target district through inquiring the district change attribute of the adjacent district in the adjacent relation table, namely when confirming that the target district allows the terminal device to access according to the district change attribute of the adjacent district in the adjacent relation table, send the district change request to the base station of the target district, and when confirming that the target district does not allow the terminal device to access according to the district change attribute, can needn't send the district change request to the base station of the target district, thus can save the resources of the base station and raise the efficiency of changing the district.
Referring to fig. 1, a flow chart of steps of an embodiment of a handover method of the present invention is shown; the method specifically comprises the following steps:
Aiming at each cell, configuring the access conditions of the cell, such as not allowing the access of terminal equipment with the uplink rate requirement exceeding 1M/s, or not allowing the access of terminal equipment managed by a neighboring cell in the time period of 10:00am-10:00pm, and the like; and then the configuration information can be sent to the base station of the adjacent cell, so that the base station can change the attribute for the cell configured for the corresponding adjacent cell in the adjacent cell relation table according to the configuration information. The configuration information may include a cell change attribute of the neighboring cell, a corresponding attribute value, a cell identifier of the neighboring cell, and the like, where the cell change attribute may be an attribute for determining whether to use the neighboring cell as a serving cell of the terminal device, and may include multiple attributes, such as whether to change an attribute of an auxiliary cell of the terminal device, whether to add an attribute of an auxiliary cell to the terminal device, whether to switch the terminal device to an attribute of a target cell, and the like; the neighbor relation table may include attribute information of the neighbor, such as a cell identifier of the neighbor, and may include handover information of the neighbor, such as a cell change attribute and a corresponding attribute value. And the base station can determine the cell identification, the cell change attribute and the corresponding attribute value corresponding to the configuration information, and then update the attribute value of the cell change attribute of the corresponding neighbor cell in the neighbor cell relation table according to the cell identification. The base station may configure corresponding cell change attributes for the neighboring cells in the neighboring cell relation tables of all the cells, or may configure corresponding cell change attributes for the neighboring cells in the neighboring cell relation tables of several cells.
And step 102, inquiring the cell change attribute of the adjacent cell in the adjacent cell relation table.
In the embodiment of the invention, aiming at each cell, a base station can directly judge whether the adjacent cell of the cell is used as a target cell of terminal equipment; or issuing a measurement event (such as an A3 event, an a4 event, etc.) to the terminal device, and then determining whether to use the neighboring cell of the cell as the target cell of the terminal device according to the measurement report reported by the terminal device. Therefore, when the base station determines that the neighboring cell of the cell is used as the target cell of the terminal device, the base station can judge whether to send a cell change request to the base station of the target cell by inquiring the cell change attribute of the neighboring cell in the neighboring cell relation table corresponding to the cell; the queried cell change attribute may be a cell change attribute corresponding to the target cell, or a cell change attribute corresponding to another neighboring cell associated with the target cell.
Step 103, judging whether to send a cell change request to the base station of the target cell according to the cell change attribute.
After inquiring the cell change attribute, the embodiment of the invention can judge whether to send the cell change request to the base station of the target cell based on the attribute value of the cell change attribute, namely, if the target cell is determined to allow the terminal device to access based on the value of the cell change attribute, the cell change request can be sent to the target cell, and if the target cell is determined not to allow the terminal device to access based on the value of the cell change attribute, the cell change request does not need to be sent to the target cell. For example, if the attribute value is configured as "0" or "1", it may be determined whether the target cell allows the terminal device to access based on "0" or "1"; if the attribute value is configured as a threshold, whether the target cell allows the terminal device to access can be judged based on whether the attribute corresponding parameter meets the threshold; if the attribute value is configured as the identifier, whether the target cell allows the terminal device to access can be judged based on the identifier.
In the embodiment of the present invention, if it is determined that the cell change request can be sent to the base station of the target cell, the operation of sending the cell change request to the base station of the target cell may be performed, that is, resource preparation such as obtaining an identifier of the terminal device, a service identifier, uplink/downlink rate requirement information, and the like may be performed, and then the cell change request is sent to the base station of the target cell; if it is determined that it is not necessary to send a cell change request to the base station of the target cell, the ending step may be performed, i.e., it is not necessary to send a cell change request to the base station of the target cell; and further saves the resources of the base station. The request sent to the base station of the target cell may include multiple types, for example, the request may be a cell handover request for switching the terminal device to the target cell, and may also be, for example, a secondary cell addition request for adding the target cell as a secondary cell of the terminal device, or may also be, for example, a secondary cell change request for changing the secondary cell of the terminal device to the target cell, and the like, which is not limited in the embodiment of the present invention.
The embodiment of the invention can configure the corresponding cell change attribute for the adjacent cell in the adjacent cell relation table according to the configuration information, and further can judge whether to send a cell change request to a base station of a target cell according to the cell change attribute by inquiring the cell change attribute in the adjacent cell relation table in the switching process; thereby saving the resources of the base station and improving the efficiency of changing the cell.
In another embodiment of the present invention, the manner of determining that the target cell is the serving cell of the terminal device may include multiple manners, for example, if the terminal device is a single connection, it may be determined whether to switch the terminal device to the target cell or add the target cell as the secondary cell of the terminal device; for another example, if the terminal device is in dual connectivity (i.e., the terminal device is connected to two cells, and the two cells serve the terminal device, and the two cells include a primary cell and a secondary cell), it may be determined whether to change the terminal device from dual connectivity to single connectivity (i.e., to connect only with the target cell), or to change the secondary cell of the terminal device to the target cell, and so on. Then, the corresponding cell change attribute can be inquired from the neighbor cell relation table, and whether to send the corresponding request to the target cell is judged according to the inquired cell change attribute.
The method for using the target cell as the serving cell of the terminal device may include at least one of the following: and changing the auxiliary cell of the terminal equipment into a target cell, adding the target cell into the auxiliary cell of the terminal equipment, and switching the terminal equipment to the target cell. The cell change attribute may correspond to at least one of: the secondary cell change attribute, the secondary cell addition attribute and the switching cell condition attribute; the secondary cell change attribute may be an attribute for determining whether to change a secondary cell of the terminal device, the secondary cell addition attribute may be an attribute for determining whether to add a secondary cell to the terminal device, and the handover cell condition attribute may be an attribute having a limitation for handing over the terminal device to the target cell. Of course, in the embodiment of the present invention, the cell change attribute may also include other attributes, which is not limited in the present invention. In the embodiment of the present invention, different ways of using the target cell as the serving cell of the terminal device correspond to different queried cell change attributes, such as changing the secondary cell of the terminal device to the target cell to correspondingly query a secondary cell change attribute, adding the target cell to the secondary cell of the terminal device to correspondingly query a secondary cell addition attribute, and switching the terminal device to the target cell to correspondingly query a handover cell condition attribute.
Referring to fig. 2, a flow chart of steps of an embodiment of a secondary cell change method of the present invention is shown; the method specifically comprises the following steps:
In the embodiment of the invention, after the cell configures the access condition, on one hand, the configuration information can be sent to the base station of the neighboring cell through an air interface (such as an X2 interface) between the corresponding base station and the base station of the neighboring cell; on the other hand, the configuration information can be sent to the base station of the neighboring area through the base station operation management system by the operation of the user in the base station operation management system. And the base station can configure the corresponding cell change attribute for the neighboring cell in the neighboring cell relation table according to the received configuration information, wherein the configuring the corresponding cell change attribute for the neighboring cell can include configuring an attribute value for the cell change attribute corresponding to the neighboring cell. Wherein the cell change attribute comprises: secondary cell Change attribute (SN Change), Secondary cell Add attribute (SN Add), Handover cell Condition attribute (Condition Handover), removal attribute (Remove), X2 attribute (X2), and Handover cell attribute (Handover). In the neighbor relation table, if the secondary cell Change attribute is identified as SN Change, it indicates whether to allow the terminal device to access according to the attribute value of the secondary cell Change attribute; and if the secondary cell Change attribute is identified as No SN Change, judging whether the terminal equipment is not allowed to access according to the attribute value of the secondary cell Change attribute. If the adding attribute of the auxiliary cell is marked as SN Add, judging whether the terminal equipment is allowed to access or not according to the attribute value of the adding attribute of the auxiliary cell; and if the adding attribute of the auxiliary cell is identified as No SN Add, judging whether the terminal equipment is not allowed to access according to the attribute value of the adding attribute of the auxiliary cell. If the switching cell Condition attribute is identified as Condition Handover, judging whether the terminal equipment is allowed to access according to the attribute value of the switching cell Condition attribute; and if the Condition attribute of the switching cell is marked as No Condition Handover, judging whether the terminal equipment is not allowed to access according to the attribute value of the Condition attribute of the switching cell. If the removal attribute is identified as Remove, judging whether the terminal equipment is allowed to access according to the attribute value of the removal attribute; and if the removal attribute is identified as No Remove, judging whether the terminal equipment is not allowed to access according to the attribute value of the removal attribute. If the X2 attribute is marked as X2, the attribute value of the X2 attribute is used for judging whether the terminal equipment is allowed to access; if the attribute X2 is identified as No X2, it indicates that whether the terminal device is not allowed to access is determined according to the attribute value of the X2 attribute. If the attribute of the switching cell is identified as Handover, judging whether the terminal equipment is allowed to access according to the attribute value of the attribute of the switching cell; and if the attribute of the switching cell is marked as No Handover, judging whether the terminal equipment is not allowed to access according to the attribute value of the attribute of the switching cell.
Taking table 1 as an example of the present invention, wherein, the Neighbor Cell Identity (Neighbor), the Target Cell Identity (TCI).
TABLE 1
Wherein:
no SN change: the attribute value has a mark of 'check mark', and can represent that the auxiliary cell of the terminal equipment is not allowed to be changed into a neighboring cell; and if the attribute value is null, the secondary cell of the terminal equipment can be changed into the adjacent cell.
No SN: the attribute value has a 'hook' mark, and can represent that the neighbor cell is not allowed to be added as the auxiliary cell of the terminal equipment; and if the attribute value is null, the attribute value can represent the auxiliary cell allowing the neighbor cell to be added as the terminal equipment.
No Condition Handover: the attribute value has a mark of 'check mark', which can represent that the terminal device which does not meet the condition is not allowed to be switched to the adjacent region; and if the attribute value is null, no conditional constraint on the terminal equipment switched to the adjacent cell can be represented.

No X2: the attribute value has a mark of 'check mark', and can represent the initial process of the neighborhood relation which can not be carried out by utilizing an X2 interface; the attribute value is null, which can characterize the initial process of the neighbor relation by using an X2 interface.
No Handover: the attribute value has a mark of 'check mark', and can represent that the terminal device is not allowed to be switched to the adjacent region, and the attribute value is null, and can represent that the terminal device is allowed to be switched to the adjacent region.
Of course, the attribute value of each cell change attribute may also be configured as "1" or "0", and may also be configured as a specific numerical value, which is not limited in the embodiment of the present invention.
The embodiment of the invention can determine the mode that the target cell is used as the service cell of the terminal equipment, and determine the cell change attribute to be inquired according to the determined mode. In the embodiment of the present invention, a manner of using a target cell as a serving cell of the terminal device is as follows: changing the auxiliary cell of the terminal equipment into a target cell, wherein the terminal equipment is in dual connection; and then the change attribute of the auxiliary cell of the adjacent cell in the adjacent cell relation table can be inquired.
In this embodiment of the present invention, the secondary cell change attribute may be an attribute set for two neighboring cells, where one neighboring cell is a neighboring cell associated with another neighboring cell. The secondary cell change attribute may have bidirectionality, for example, the secondary cell change attribute is configured between the neighboring cell 1 and the neighboring cell 2, and if the attribute value of the secondary cell change attribute of the neighboring cell 1 does not have the "√" flag, it is determined that the secondary cell of the terminal device is allowed to be changed from the neighboring cell 1 to the neighboring cell 2, and the secondary cell of the terminal device is also allowed to be changed from the neighboring cell 2 to the neighboring cell 1. Of course, the secondary cell change attribute may also be refined, that is, the secondary cell change attribute may include: the method comprises the steps that a secondary cell forward change attribute and a secondary cell reverse change attribute are provided, and both the secondary cell forward change attribute and the secondary cell reverse change attribute have unidirectionality; for example, if the attribute value of the forward change attribute of the secondary cell of the neighboring cell 1 is null, it is determined that the secondary cell of the terminal device is allowed to be changed from the neighboring cell 1 to the neighboring cell 2, and if the attribute value of the reverse change attribute of the secondary cell of the neighboring cell 1 is null, it is determined that the secondary cell of the terminal device is allowed to be changed from the neighboring cell 2 to the neighboring cell 1; if the attribute value of the forward change attribute of the secondary cell of the neighboring cell 1 has the identifier of "√" then it is determined that the secondary cell of the terminal device is not allowed to be changed from the neighboring cell 1 to the neighboring cell 2, and if the attribute value of the reverse change attribute of the secondary cell of the neighboring cell 1 has the identifier of "√" then it is determined that the secondary cell of the terminal device is not allowed to be changed from the neighboring cell 2 to the neighboring cell 1. The forward change attribute and the reverse change attribute of the secondary cell for the neighboring cell 2 are similar to those of the neighboring cell 1, and are not described herein again.
Therefore, when inquiring the change attribute of the auxiliary cell of the neighboring cell in the neighboring cell relation table, if the change attribute of the auxiliary cell has bidirectionality, the change attribute of the auxiliary cell of the target cell can be inquired, and the change attribute of the auxiliary cell can also be inquired; if the secondary cell change attribute comprises: the secondary cell reverse change attribute and the secondary cell reverse change attribute may be queried for the secondary cell reverse change attribute of the target cell, or for the secondary cell forward change attribute.
In the embodiment of the present invention, the cell change request sent to the base station of the target cell may be a secondary cell change request; that is, after the secondary cell change attribute is queried, whether to send a secondary cell change request to the base station of the target cell can be determined according to the attribute value of the secondary cell change attribute. Specifically, whether the target cell allows the terminal device to access or not can be judged according to the attribute value of the change attribute of the auxiliary cell; for example, if the attribute value of the secondary cell change attribute of the query target cell has the "√" flag, it may be determined that the target cell does not allow the terminal device to access, and if the attribute value of the secondary cell change attribute of the query target cell is null, it may be determined that the target cell allows the terminal device to access. For another example, if the attribute value of the secondary cell reverse change attribute of the target cell is queried to have the "√" flag, it can be determined that the target cell does not allow the terminal device to access, and if the attribute value of the secondary cell reverse change attribute of the target cell is queried to be null, it can be determined that the target cell allows the terminal device to access. After determining that the target cell allows the terminal device to access, determining that an auxiliary cell change request can be sent to a base station of the target cell, namely resource preparation can be carried out, and sending the auxiliary cell change request to the base station of the target cell; after determining that the target cell does not allow the terminal device to access, it may be determined that it may not be necessary to send a secondary cell change request to the base station of the target cell.
In the embodiment of the present invention, the secondary cell change request may be used to instruct to change the secondary cell of the terminal device to the target cell, that is, the subsequent base station may send a secondary cell change instruction to the terminal device according to a response message returned by the base station of the target cell; and after receiving the secondary cell change instruction, the terminal equipment can switch the secondary cell from the current cell to the target cell.
In an example of the present invention, a terminal device is connected to a cell 1 and a cell 2, respectively, where the cell 1 is a primary cell, the cell 2 is a secondary cell, and the cell 3 is a target cell; if the attribute value of the secondary cell change attribute of the cell 3 in the neighbor cell relation table is queried to be null, a secondary cell change request can be sent to the base station of the cell 3, and then the secondary cell of the terminal device can be changed from the cell 2 to the cell 3, that is, the terminal device is respectively connected with the cell 1 and the cell 3, wherein the cell 1 is a main cell and the cell 3 is a secondary cell.
The embodiment of the invention can configure the corresponding cell change attribute for the neighboring cell in the neighboring cell relation table according to the configuration information, and further, the mode of determining that the target cell is used as the service cell of the terminal equipment is as follows: when the auxiliary cell of the terminal equipment is changed into the target cell, the auxiliary cell change attribute of the adjacent cell in the adjacent cell relation table can be inquired, and then whether an auxiliary cell change request is sent to a base station of the target cell or not is judged according to the auxiliary cell change attribute; therefore, when the fact that the secondary cell change request can be sent to the base station of the target cell is determined, the secondary cell change request is sent to the base station of the target cell, and when the fact that the secondary cell change request cannot be sent to the base station of the target cell is determined, the secondary cell change request does not need to be sent to the base station of the target cell, so that resources of the base station can be saved, and the efficiency of changing the secondary cell by the terminal equipment can be improved.
Secondly, in this embodiment of the present invention, the secondary cell change attribute may include: the secondary cell forward change attribute and the secondary cell reverse attribute can be set to be unidirectional, and then whether the granularity of a secondary cell change request is sent to a base station of a target cell or not is finely judged, so that the efficiency of changing the secondary cell by the terminal equipment is further improved.
Referring to fig. 3, a flowchart illustrating steps of an embodiment of a secondary cell addition method according to the present invention is shown; the method specifically comprises the following steps:
This step is similar to step 201 described above and will not be described herein again.
This step is similar to step 202 described above and will not be described further herein. In an embodiment of the present invention, a way of determining that a target cell is a serving cell of the terminal device is as follows: adding a target cell as a secondary cell of a terminal device, wherein the terminal device is in single connection; and then, the auxiliary cell addition attribute of the target cell in the neighbor cell relation can be inquired.
And step 303, judging whether to send a secondary cell addition request to the target cell according to the secondary cell addition attribute.
In the embodiment of the present invention, the cell change request sent to the base station of the target cell may be an auxiliary cell addition request; that is, after the attribute of the secondary cell is queried, whether to send a secondary cell change request to the base station of the target cell can be determined according to the attribute value of the attribute of the secondary cell. Specifically, whether the target cell allows the terminal device to access or not can be judged according to the attribute value of the change attribute of the auxiliary cell; for example, if the attribute value of the secondary cell addition attribute of the query target cell has the "√" flag, it may be determined that the target cell does not allow the terminal device to access, and if the attribute value of the secondary cell addition attribute of the query target cell is null, it may be determined that the target cell allows the terminal device to access. After determining that the target cell allows the terminal device to access, determining that an auxiliary cell adding request can be sent to a base station of the target cell, namely resource preparation can be carried out, and sending the auxiliary cell adding request to the base station of the target cell; after determining that the target cell does not allow the terminal device to access, it may be determined that the secondary cell addition request does not need to be sent to the base station of the target cell.
In the embodiment of the present invention, the secondary cell addition request may be used to indicate that the target cell is added as the secondary cell of the terminal device, that is, the subsequent base station may send a secondary cell addition instruction to the terminal device according to a response message returned by the base station of the target cell; and after receiving the auxiliary cell adding instruction, the terminal equipment can be connected to the target cell and takes the target cell as the auxiliary cell of the terminal equipment.
In an example of the present invention, a terminal device is connected to a cell 1, the cell 2 is a target cell, and if an attribute value of an auxiliary cell addition attribute of the cell 2 in a neighbor relation table is queried to be null, an auxiliary cell addition request may be sent to a base station of the cell 2, and then the cell 2 may be added as an auxiliary cell of the terminal device, that is, the terminal device is connected to the cell 1 and the cell 2, respectively, where the cell 1 is a primary cell and the cell 2 is an auxiliary cell.
The embodiment of the invention can configure the corresponding cell change attribute for the neighboring cell in the neighboring cell relation table according to the configuration information, and further, the mode of determining that the target cell is used as the service cell of the terminal equipment is as follows: when the target cell is added as the auxiliary cell of the terminal equipment, the auxiliary cell addition attribute of the target cell in the neighbor relation table can be inquired, and then whether an auxiliary cell addition request is sent to the target cell or not is judged according to the auxiliary cell addition attribute; therefore, when the fact that the auxiliary cell adding request can be sent to the base station of the target cell is determined, the auxiliary cell adding request is sent to the base station of the target cell, and when the fact that the auxiliary cell adding request cannot be sent to the base station of the target cell is determined, the fact that the auxiliary cell adding request is sent to the base station of the target cell is not needed, therefore, not only can the resources of the base station be saved, but also the efficiency of adding the auxiliary cell by the terminal equipment can be improved.
In another embodiment of the present invention, whether the terminal device is in single connection or dual connection, the terminal device may be switched to the target cell, for example, the terminal device is in single connection to the cell 1, and the terminal device may be switched to the cell 3, and for example, the terminal device is in dual connection to the cell 1 (primary cell) and the cell 2 (secondary cell), and the terminal device is in dual connection to the cell 3 (primary cell) and the cell 2 (secondary cell), and may also be switched to the cell 3 (i.e., dual connection is switched to single connection). Therefore, when determining that the target cell is used as the serving cell, when the terminal device is switched to the target cell, the handover cell condition attribute of the target cell may be queried to determine whether to send a cell handover request to the base station of the target cell. In this embodiment of the present invention, the handover cell condition attribute includes at least one of the following: network performance attribute, service type attribute and signal intensity attribute; the network performance attribute may be an attribute for determining whether to switch the terminal device to the target cell according to the network performance of the terminal device, the service type attribute may be an attribute for determining whether to switch the terminal device to the target cell according to the service type of the terminal device, and the signal strength attribute may be an attribute for determining whether to switch the terminal device to the target cell according to the signal strength of the serving cell and the signal strength of the target cell. Of course, the handover cell condition attribute may also include other attributes, which is not limited in the present invention. See table 2:
TABLE 2
Wherein:
network performance attributes: if the attribute value exists, determining that the neighboring cell does not allow the terminal equipment with the network performance higher than the first threshold value to access; if the attribute value is null, it can be determined that the neighboring cell does not limit the network performance of the access terminal device. The network performance may include an uplink rate, a downlink rate, a network delay, and the like of the terminal device, the first threshold may be set according to a requirement, for example, the downlink rate is 600k/s, and the attribute value of the network performance attribute may be the first threshold, or may be another value or identifier. For example, if the attribute value of the network performance attribute is the first threshold value, the network performance is the uplink rate, and when the attribute value of the network performance attribute of the neighboring cell 1 is X, it is determined that the cell 1 does not allow the terminal device with the uplink rate requirement higher than X to access.
Service type attribute: if the attribute value exists, the terminal equipment with the service type being the preset type is not allowed to be accessed in the adjacent region; if the attribute value is null, the service type of the access terminal device which is not limited by the adjacent cell can be determined. The preset type may be set as required, such as an internet of vehicles service, a broadcast service, and the like, and the attribute value of the service type attribute may be a number corresponding to the preset type, or may be another numerical value or an identifier. For example, if the attribute value of the service type attribute is a number corresponding to a preset type, and if the attribute value of the service type attribute of the neighboring cell 1 is E and the service type corresponding to E is the car networking service, it is determined that the cell 1 does not allow the terminal device with the service type being the car networking service to access.
Signal strength properties: if the attribute value exists, determining that the terminal equipment is allowed to access when the difference value between the signal intensity of the adjacent cell and the signal intensity of the serving cell is higher than the serving cell of a second threshold value; if the attribute value is null, the signal intensity difference value between the adjacent cell and the service cell can be determined without being limited by the adjacent cell. Wherein the second threshold may be set as desired, such as 5 dB; the attribute value of the signal strength attribute may be a second threshold value, or may be other numerical value or identification. For example, the attribute value of the signal strength attribute is the second threshold, when the attribute value of the signal strength attribute of the neighboring cell 1 is H, whether the signal strength difference between the neighboring cell 1 and the serving cell is greater than H is calculated, and if the signal strength difference is greater than H, the terminal device of the serving cell is allowed to access the neighboring cell 1.

Then judging whether to send a cell switching request to a base station of a target cell or not according to the attribute value of the condition attribute of the switching cell; for example, if the attribute value of the network performance attribute is set to the first threshold, it may be determined whether the value of the network performance required by the terminal device is lower than the attribute value when it is found that the attribute value of the network performance attribute of the target cell is not null, and if the value of the network performance required by the terminal device is lower than the attribute value, it is determined that the terminal device is allowed to access the target cell; and if the value of the network performance required by the terminal equipment is higher than the attribute value, determining that the target cell does not allow the terminal equipment to access. If the attribute value of the network performance attribute is set as the identifier, after the attribute value of the network performance attribute of the target cell is inquired to have the identifier, whether the value of the network performance required by the terminal device is lower than a first threshold value or not can be judged, and if the value of the network performance required by the terminal device is lower than the first threshold value, the target cell is determined to allow the terminal device to access; and if the value of the network performance required by the terminal equipment is higher than the first threshold value, determining that the target cell does not allow the terminal equipment to access. For another example, if the attribute value of the service type attribute is set as the service type number, and if it is found that the attribute value of the service type attribute of the target cell is not null, determining the service type corresponding to the attribute value, then judging whether the service type of the terminal device is the service type, and if it is determined that the service type of the terminal device is the service type, determining that the target cell does not allow the terminal device to access; and if the service type of the terminal equipment is determined not to be the service type, determining that the target cell allows the terminal equipment to access. For example, if the attribute value of the signal strength attribute is set as the second threshold, if it is found that the attribute value of the signal strength attribute of the target cell is not null, the signal strength difference between the target cell and the serving cell may be calculated, and if the difference is lower than the attribute value, it is determined that the target cell does not allow the terminal device to access; and if the difference value is higher than the attribute value, determining that the target cell allows the terminal equipment to access.
