Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method and an apparatus for determining members of a blacklist.
Background
In a mobile communication network in which a Femto base station is deployed, a UE (User Equipment) needs to meet a current service requirement by switching a service base station in multiple scenarios, where the switching of the service base station includes switching between the Femto base station and the Femto base station, switching between the Femto base station and a macro base station, and switching between the macro base station and the macro base station. In general, when a UE is handed over from a Femto base station to a macro base station, there is only one target cell; however, in the handover between the macro base station and the Femto base station, and the handover between the Femto base station and the Femto base station, a plurality of handover target cells may exist.
Generally, before the UE switches the serving base station, the UE measures cells on each frequency point according to measurement configuration (mainly including a measurement object and reporting configuration) issued by the network side. According to the LTE (Long Term Evolution ) protocol description, when a measurement configuration is issued, a cell blacklist may be configured in a measurement object. In the process of measuring and reporting the cell, the UE does not perform measurement reporting operation on the cell in the blacklist. Only the role of blacklisting is disclosed in the LTE protocol, but there is no solution to determine the members of the blacklist. The reasonability of the configuration of the blacklist determines the measurement efficiency of the UE before the service base station is switched, and determines that the base station switched for the UE can well serve the UE. Therefore, how to determine the members of the blacklist and configure the most reasonable blacklist for different UEs is an urgent problem to be solved.
Disclosure of Invention
The invention aims to provide a method and a device for determining members of a blacklist, which are used for overcoming the problem that the configuration of the blacklist is not realized in the related technology.
The invention provides a method for determining members of a blacklist, which comprises the following steps:
judging whether a User Equipment (UE) and a serving cell are in an RRC (radio resource control) state (when in a connection state, whether the adjacent cell of the serving cell meets the current access requirement of the UE currently or not;
and when the adjacent cell does not meet the current access requirement of the UE, determining the adjacent cell as a member of a blacklist of the UE.
The embodiment of the invention realizes that the neighbor cell which can not meet the current access requirement of the UE which is served is determined as the member of the blacklist, so that the member of the blacklist can be added into the blacklist of the UE, thereby realizing the configuration and optimization of the blacklist. When UE (user equipment) performs neighbor cell measurement to complete neighbor cell switching, the number of measured neighbor cells is reduced and the power consumption of the UE is reduced by not measuring the neighbor cells in the blacklist; by excluding the neighbor cells in the blacklist, the measurement is only performed on the neighbor cells meeting the current access requirement of the UE, so that the measurement accuracy of the neighbor cells which are possibly switched to be used is improved; when the measurement result is reported, and the measurement report of the adjacent cell in the blacklist list is reduced when the measurement result of the adjacent cell is reported, so that the load of the bandwidth of the network side is reduced, and the utilization rate of the bandwidth is improved; in the pilot frequency measurement, the UE can reduce the times of suspending the current service transmission for the neighbor cell measurement, thereby enabling the service to be performed more normally.
Determining that the neighboring cell does not satisfy the current access requirement of the UE when it is determined that the neighboring cell satisfies one or more of the following conditions: the current available air interface resource of the adjacent cell does not meet the estimated air interface resource currently required by the service quality Qos of the UE, the current backhaul bandwidth gear of the adjacent cell is higher than a first preset gear, and the current hardware resource gear of the adjacent cell is higher than a second preset gear; or,

According to the embodiment of the invention, the moving range of the UE is predicted, and the adjacent cell which is not in the moving range is determined as the member of the blacklist of the UE, so that the adjacent cell is added into the blacklist when the blacklist is configured, and the UE is convenient to measure the adjacent cell without measuring the adjacent cell.
The method further comprises the following steps:
acquiring the current position of the UE;
determining the distance between the adjacent cell and the UE according to the current position of the UE;
and when the distance between the adjacent cell and the UE is larger than or equal to a preset threshold value, determining that the adjacent cell is a member of a blacklist of the UE.
According to the embodiment of the invention, when the neighboring cell is far away from the UE, the UE cannot be switched to the neighboring cell in the current or short time, and the neighboring cell whose distance from the UE is not at the preset threshold value is determined as a member of a blacklist of the UE, so that the neighboring cell is added to the blacklist when the blacklist is configured, and the UE is convenient for not measuring the neighboring cell when the neighboring cell is measured.
The method further comprises the following steps:

Detailed Description
The embodiments of the present invention will be described in conjunction with the accompanying drawings, and it should be understood that the embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The embodiment of the invention provides a method for determining members of a blacklist, which is used for a network side, and the method can be used for a network which can configure the blacklist so as to facilitate UE to perform neighbor cell measurement according to the blacklist and complete neighbor cell switching, such as a communication network for intensively deploying Femto base stations, and the embodiment of the invention is not limited.
The method for determining the blacklist member provided by the embodiment of the invention determines the adjacent cell which can not meet the current access requirement of the UE which is served as the blacklist member and adds the adjacent cell to the blacklist of the UE, thereby realizing the configuration of the blacklist. When UE (user equipment) performs neighbor cell measurement to complete neighbor cell switching, the number of measured neighbor cells is reduced and the power consumption of the UE is reduced by not measuring the neighbor cells in the blacklist; by excluding the neighbor cells in the blacklist, the measurement is only performed on the neighbor cells meeting the current access requirement of the UE, so that the measurement accuracy of the neighbor cells which are possibly switched to be used is improved; when the measurement result is reported, and the measurement report of the adjacent cell in the blacklist list is reduced when the measurement result of the adjacent cell is reported, so that the load of the bandwidth of the network side is reduced, and the utilization rate of the bandwidth is improved; in the pilot frequency measurement, the UE can reduce the times of suspending the current service transmission for the neighbor cell measurement, thereby enabling the service to be performed more normally. The following describes in detail a method for determining members of a blacklist in an embodiment of the present invention.
As shown in fig. 1, a flowchart of a method for determining members of a blacklist in an embodiment of the present invention includes steps 101 to 102:
step 101: judging whether the adjacent cell of a service cell meets the current access requirement of User Equipment (UE) when the UE and the service cell are in an RRC connection state.
Step 102: and when the adjacent cell does not meet the current access requirement of the UE, determining the adjacent cell as a member of a blacklist of the UE.
Wherein, in one embodiment, the neighboring cell is determined not to satisfy the current access requirements of the UE when it is determined that the neighboring cell satisfies one or more of the following conditions:
(1) and the current available air interface resource of the adjacent cell does not meet the pre-estimated air interface resource currently required by the Qos of the UE: for example, the current available air interface Resource of the neighboring cell may be determined according to formula (1), and the current available air interface Resource may include an available uplink PRB (Physical Resource Block) and an available downlink PRB;
s1＝s2-s3-s4(1)
wherein s is1Representing the current available air interface resources of the adjacent cells; s2Representing the total air interface resource of the adjacent area; s3Indicating the used air interface resources of the adjacent cell; s4Indicating reserved air interface resources, which may be a first threshold that may be set.
It should be noted that, the present invention is not limited herein, and whether the current available air interface resource of the neighboring cell can satisfy the pre-estimated air interface resource required by the Qos of the UE can be evaluated by using the prior art.
(2) The current return bandwidth gear of the adjacent region is higher than a first preset gear: for example, when the return bandwidth gear is represented by four gears, the gears are sequentially from low to high: l (indicating that backhaul bandwidth is sufficient), M (indicating that backhaul bandwidth resources are sufficient), H (indicating that backhaul bandwidth resources are insufficient), and O (indicating that backhaul bandwidth resources are overloaded), the corresponding first preset gear may be set to the M gear, where the first preset gear indicates that when the backhaul bandwidth gear of the neighboring cell is higher than the M gear (i.e., in the H or O gear), backhaul bandwidth of the neighboring cell is insufficient and cannot normally serve the UE, and therefore cannot meet the current access requirement of the UE.
(3) The current hardware resource gear of the adjacent region is higher than a second preset gear: the hardware resources include processor resources, memory resources, and interface I/O (INPUT/OUTPUT device interface) hardware resources. When the hardware resource gears are represented by four gears, the gears are sequentially from low to high: l (indicating that hardware resources are sufficient), M (indicating that hardware resources are sufficient), H (indicating that hardware resources of a base station are insufficient), and O (indicating that hardware resources are overloaded), a corresponding second preset gear may be set to be an M gear, and the second preset gear indicates that when a hardware resource gear of a neighboring cell is higher than the M gear (i.e., in the H or O gear), hardware resources of the neighboring cell are insufficient and cannot normally serve the UE, so that a current access requirement of the UE cannot be met.
It should be noted that the first preset gear and the second preset gear may be the same or different.
Or, it may also be determined that the neighboring cell does not satisfy the current access requirement of the UE when it is determined that the neighboring cell satisfies one or more of the following conditions:
(1) and the current available air interface resource of the adjacent cell does not meet the estimated air interface resource currently required by the Qos of the UE. The method for determining the currently available air interface resource has been described in detail in the foregoing, and is not described herein again.
(2) And the current available backhaul bandwidth resource of the neighboring cell does not meet the estimated backhaul bandwidth currently required by the Qos of the UE: the current available backhaul bandwidth resource of the neighboring cell can be estimated according to the backhaul bandwidth tap of the neighboring cell and the range of the resource amount corresponding to the preset tap, and therefore, the available backhaul bandwidth resource can be a range or a determined value. It should be noted that the currently available backhaul bandwidth resources may be determined according to the prior art, and are not limited herein. The estimated backhaul bandwidth currently required by the Qos of the UE may be a backhaul bandwidth currently required by a Qos estimated according to a current service of a user, where the estimated backhaul bandwidth currently required by the Qos may be a range or a determined value, it needs to be noted that a currently available backhaul bandwidth resource may be determined according to the prior art, and is not limited herein; and when the currently available backhaul bandwidth resources are less than the backhaul bandwidth required by the estimated Qos, the current access requirement of the UE is not met.
(3) The current available hardware resources of the adjacent cell do not meet the estimated hardware resources required by the current service of the UE: the currently available hardware resources may be a range or a determined value, and it should be noted that the currently available hardware resources may be determined according to the prior art, and are not limited herein. The hardware resource required by the current service of the UE may be a required hardware resource estimated according to the current service of the user, the estimated required hardware resource may be a range or a determined value, it needs to be described that the currently available hardware resource may be determined according to the prior art, and no limitation is made herein; and when the currently available hardware resources are less than the hardware resources required by the estimated Qos, the current access requirement of the UE is not met.
The current available air interface resource, the backhaul bandwidth gear, and the hardware resource gear of the neighboring cell may be obtained by indicating the neighboring cell to perform cell load measurement, for example, sending a load measurement request to the neighboring cell, indicating the first neighboring cell to perform cell load measurement, and feeding back a load measurement result.
In an embodiment, the neighbor cell may be determined to be a member of the blacklist list by one or more of the following methods:
1) acquiring a moving track of the UE; predicting the moving range of the UE according to the moving track of the UE; and when the adjacent cell is not in the moving range of the UE, determining the adjacent cell as a member of a blacklist of the UE. For example, the moving direction of the UE may be determined by obtaining the moving track of the UE, and then the range to which the UE may move may be predicted according to the moving direction of the UE. For example, as shown in fig. 2, fig. 2 illustrates determining a range of movement of a UE according to an angle. In fig. 2, the moving direction of the UE is the direction indicated by the solid arrow in the figure. Then, with the UE as an angular vertex and the moving direction of the UE as a side, a preset angle is defined for each of two sides perpendicular to the moving direction of the UE, and if the preset angles on both sides can be 60 °, the final predicted moving range is 120 °, as shown by the range between the dashed arrows in fig. 2. In fig. 2, if the neighboring cell a is not within the range of 120 °, the neighboring cell a is not within the moving range of the UE. Further, the moving range may be further determined according to the distance between the neighboring cell and the UE, for example, when the distance between the neighboring cell and the UE is greater than the distance threshold, as in the neighboring cell B in fig. 2, although the neighboring cell is within the range of 120 ° determined by B in the foregoing method, the distance from the UE is too far (greater than the distance threshold), and therefore the neighboring cell B is not within the predicted moving range. It should be noted that, in the method for determining the predicted movement range, the preset angles on the two sides may be different. In addition, in the embodiment of the present invention, any method capable of predicting the moving range of the UE is applicable to the embodiment of the present invention, and is not limited herein. By predicting the moving range of the UE, the adjacent cell which is not in the moving range is determined as a member of a blacklist of the UE, so that the adjacent cell is added to the blacklist when the blacklist is configured, and the UE is convenient to measure the adjacent cell without measuring the adjacent cell.
2) Acquiring the current position of the UE; determining the distance between the adjacent cell and the UE according to the current position of the UE; and when the distance between the adjacent cell and the UE is larger than or equal to a preset threshold value, determining that the adjacent cell is a member of a blacklist of the UE. When the neighboring cell is far away from the UE, the UE is not switched to the neighboring cell in the current or short time, and the neighboring cell whose distance from the UE is not within the preset threshold value is determined as a member of a blacklist of the UE, so that the neighboring cell is added to the blacklist when the blacklist is configured, and the UE is convenient for not measuring the neighboring cell when measuring the neighboring cell.
It should be noted that, as time goes on and the environment changes, the state of the neighbor may change, for example, the neighbor in the blacklist may have a good current state and actually become not a member of the blacklist, while the neighbor not in the blacklist may have a poor current state and actually become a member of the blacklist. Therefore, after the blacklist is established for the first time according to the determined blacklist member, the blacklist is stored, the serving cell periodically re-determines the blacklist member when the UE is resident in the serving cell all the time, and the blacklist of the UE is updated. The various methods for determining the members of the blacklist are suitable for being executed before the blacklist is created for the first time, and are also suitable for updating the blacklist after the blacklist is created. In one embodiment, the method of creating or updating a blacklist may be performed as:
judging whether a blacklist of the UE is stored;
when the blacklist of the UE is not stored, creating the blacklist of the UE, and adding the adjacent cell determined as the member of the blacklist of the UE into the blacklist of the UE;
when the blacklist of the UE is stored, if the neighbor cell which is a member of the blacklist of the UE is determined not to be in the blacklist of the UE, updating the neighbor cell to the blacklist of the UE; and if the neighbor cell which is not determined as the member of the blacklist of the UE exists in the blacklist of the UE, removing the neighbor cell from the blacklist of the UE.
The configuration of the blacklist of the UE is completed by creating the blacklist, and the validity and the reasonability of the blacklist of the UE are ensured by updating the blacklist.
In an embodiment, after updating the blacklist, the updated blacklist may be further sent to the UE through a measurement control message, and the UE is instructed to perform incremental update on its own blacklist. For example, when only one neighbor cell is added to the blacklist, only the neighbor cell and the operation of adding the neighbor cell may be notified to the UE, so that the UE performs incremental update, and the whole updated blacklist does not need to cover the blacklist of the UE itself. The embodiment of the invention realizes that the UE is instructed to update the blacklist of the UE, thereby realizing the update of the blacklist of the UE and ensuring the validity and the rationality of the blacklist of the UE. In addition, through incremental updating, the updating speed can be improved.
In an embodiment, after the UE is in an idle state or switched to a neighboring cell, the serving cell may delete the stored blacklist of the UE, so as to reduce resources that the serving cell needs to maintain and reduce a load of the serving cell.
In summary, the embodiment of the present invention determines the neighboring cell that cannot meet the current access requirement of the UE that is served as a member of the blacklist, and can establish or update the blacklist according to the member of the blacklist to configure the blacklist. When UE (user equipment) performs neighbor cell measurement to complete neighbor cell switching, the number of measured neighbor cells is reduced and the power consumption of the UE is reduced by not measuring the neighbor cells in the blacklist; by excluding the neighbor cells in the blacklist, the measurement is only performed on the neighbor cells meeting the current access requirement of the UE, so that the measurement accuracy of the neighbor cells which are possibly switched to be used is improved; when the measurement result is reported, and the measurement report of the adjacent cell in the blacklist list is reduced when the measurement result of the adjacent cell is reported, so that the load of the bandwidth of the network side is reduced, and the utilization rate of the bandwidth is improved; in the pilot frequency measurement, the UE can reduce the times of suspending the current service transmission for the neighbor cell measurement, thereby enabling the service to be performed more normally.
The method for determining the members of the blacklist in the embodiments of the present invention is described in detail below by using several simple embodiments.
Example one
Taking the initial creation of the black list of the UE as an example, the method for determining the members of the black list in the embodiment of the present invention is described in detail, as shown in fig. 3, the method includes steps 301 to 311:
step 301: and establishing connection between the serving cell where the UE is located and the adjacent cell and acquiring the position information of the adjacent cell.
The connection may be established according to an ANR (automatic neighbor relation) and a neighbor.
Wherein, the connection with the adjacent cell can be established through an X2 interface.
Step 302: and the service cell where the UE is located sends a load measurement request message to the adjacent cell, and indicates the adjacent cell to carry out cell load measurement.
After the connection with the neighboring cell is established through the X2 interface, the resource state request can be sent to the neighboring cell as a load measurement request through the X2 interface.
Step 303: and the neighbor cell receives the load measurement request message and starts to execute cell load measurement according to the load measurement request message.
Step 304: and the neighbor cell sends the load measurement result to the serving cell where the UE is located.
The neighboring cell may send the load measurement result to the serving cell where the UE is located through a resource status report message of an X2 interface.
Step 305: and the serving cell where the UE is located receives the load measurement result sent by the adjacent cell.
Step 306: and the serving cell where the UE is located acquires the current access requirement of the UE, and starts to track and acquire the movement track of the UE after determining the current position of the UE.
Wherein, the execution order of step 306 is not limited.
In an embodiment, when the UE establishes a service connection with the serving cell and enters an RRC CONNECTED (RRC CONNECTED state), the serving cell obtains a current access requirement of the UE.
In one embodiment, the serving cell creates a blacklist of the UE when the RRC connection state is initially established with the UE. Or when the serving cell determines that the neighboring cell is a member of the blacklist of the UE, it may be determined whether the blacklist of the UE is stored, and if not, the blacklist of the UE is created.
Step 307: and when the serving cell determines that the current air interface resource condition of the neighboring cell does not meet the pre-estimated air interface resource required by the Qos of the UE, adding the neighboring cell into a blacklist of the UE.
Step 308: and when the service cell determines that the current return bandwidth gear of the adjacent cell is higher than a first preset gear, determining that the adjacent cell is a member of a blacklist of the UE, and adding the adjacent cell into the blacklist of the UE.
Step 309: and when the serving cell determines that the current hardware resource gear of the neighboring cell is higher than a second preset gear, adding the neighboring cell into a blacklist of the UE.
Step 310: and when the serving cell determines that the distance between the adjacent cell and the UE is greater than or equal to a preset threshold value according to the current position of the UE, determining that the adjacent cell is a member of a blacklist of the UE and adding the adjacent cell into the blacklist of the UE.
Step 311: and the service cell predicts the movement range of the UE according to the movement track of the UE, and when the adjacent cell is not in the movement range of the UE, the service cell determines that the adjacent cell is a member of a blacklist of the UE and adds the adjacent cell into the blacklist of the UE.
The execution sequence of steps 307 to 311 is not limited. In practical applications, one or more steps from step 307 to step 311 may be selected to determine whether the neighboring cell is a member of the blacklist of the UE and add the member to the blacklist.
The embodiment of the invention realizes the initial creation of the blacklist of the UE and the configuration of the blacklist. When UE (user equipment) performs neighbor cell measurement to complete neighbor cell switching, the number of measured neighbor cells is reduced and the power consumption of the UE is reduced by not measuring the neighbor cells in the blacklist; by excluding the adjacent cells in the blacklist, the measurement is only carried out on the adjacent cells which can ensure the normal work of the UE, so that the measurement accuracy of the adjacent cells which are possibly switched to be used is improved; when the measurement result is reported, and the measurement report of the adjacent cell in the blacklist list is reduced when the measurement result of the adjacent cell is reported, so that the load of the bandwidth of the network side is reduced, and the utilization rate of the bandwidth is improved; in the pilot frequency measurement, the UE can reduce the times of suspending the current service transmission for the neighbor cell measurement, thereby enabling the service to be performed more normally.
Example two
Taking the example of periodically updating the blacklist of the UE after the blacklist is initially created as an example, the method for determining the members of the blacklist in the embodiment of the present invention is described in detail, as shown in fig. 4, the method includes steps 401 to 405:
in an embodiment, when the load measurement request information is sent to the neighboring cell for the first time, the neighboring cell is instructed to periodically perform cell load measurement and send a load measurement result, so that the load measurement result of the neighboring cell is periodically received later to determine a member of a blacklist of the UE again, and update of the blacklist of the UE is facilitated.
Step 401: and when the periodic updating time is reached, the serving cell acquires the load measurement result of the neighboring cell and the current access requirement of the UE.
Step 402: and when the serving cell determines that the neighbor cell does not meet the current access requirement of the UE, determining that the neighbor cell is a member of a blacklist of the UE.
Step 403: and when the serving cell determines that the distance between the adjacent cell and the UE is greater than or equal to a preset threshold value according to the current position of the UE, determining that the adjacent cell is a member of a blacklist list of the UE.
Step 404: and the service cell tracks the movement track of the UE, predicts the movement range of the UE according to the movement track of the UE, and determines the adjacent cell as a member of a blacklist of the UE when the adjacent cell is not in the movement range of the UE.
The execution sequence of steps 402-404 is not limited.
Step 405: the serving cell acquires a blacklist of the UE, and updates the neighbor cell which is determined to be a member of the blacklist of the UE but not in the blacklist of the UE into the blacklist of the UE; and removing the neighbor cells which exist in the blacklist of the UE but are not determined as the blacklist members of the UE from the blacklist of the UE.
In an embodiment, the serving cell may further issue the blacklist after step 405 to the UE through a measurement control message, so as to ensure that the UE performs neighbor cell measurement according to the updated blacklist, and ensure validity and accuracy of the neighbor cell measurement.
In an embodiment, the stored blacklist of the UE may be deleted after the UE is switched to the neighboring cell.
The embodiment of the invention is convenient for periodically updating the blacklist of the UE by periodically determining the members of the blacklist, so as to ensure the validity and the reasonability of the blacklist and realize the optimization of the blacklist.
