PCI of all cells; when the user equipment 11 first enters the cluster private network, the first PCI list is sent to the user equipment 11, wherein the first PCI list is used by the user equipment 11 for cell selection.

The method for cell selection provided by the embodiment of the present invention is described below in conjunction with the foregoing system.

FIG. 2 is a schematic flowchart of a method for performing cell selection by a cluster-dedicated communication system according to an embodiment of the present invention. Referring to FIG. 2, the method includes:

S201: The base station reports the PCI of all the cells under its jurisdiction to the OAM entity when the cluster private network is created, expanded, or reduced.

Specifically, a cluster private network may include one or more base stations, and when the cluster private network is created, expanded, or reduced, the base station reports the PCI of all the cells under its jurisdiction to the OAM entity, and then the OAM entity aggregates the cells. PCI, generates the first PCI list, this table includes the PCI of all cells in the cluster private network, and then the OAM entity will The table is sent to all base stations in the cluster private network.

S202: The base station receives the first PCI list from the OAM entity, where the first PCI list includes PCIs of all cells in the cluster private network.

It should be noted that several cluster private networks may exist at the same time, and each cluster private network has one PCI list, and the PCI lists of different cluster private networks are different.

S203: The base station sends the first PCI list to the user equipment.

In the specific implementation process, the first PCI list is issued and is not limited to the following two situations:

First, the base station transmits the first PCI list to the user equipment through a broadcast channel.

For example, when performing initial cell selection, the user equipment performs all available frequency point scanning on the cluster private network, determines the strongest cell, obtains the PCI of the strongest cell, and then, the user equipment reads the strongest cell based on the PCI of the strongest cell. The first PCI list on the broadcast channel, so that the user equipment obtains the first PCI list sent by the base station. Preferably, the first PCI list is carried in a System Information Block (SIB).

For example, after the OAM entity updates the first PCI list, the updated first PCI list is sent to all the base stations in the cluster private network. At this time, the base station broadcasts the updated first PCI list, and then the user equipment is reading. The broadcast channel of the serving cell or the broadcast channel of the strongest cell searched by the cell is obtained to obtain the updated first PCI list.

Second, the base station sends the first PCI list to the user equipment through dedicated signaling. For example, the user equipment may request the first PCI list from the base station periodically or as needed. At this time, the base station sends the first PCI list to the user equipment by using dedicated signaling.

For example, after the radio resource control (RRC) is established, the serving base station sends the first PCI list to the user equipment by using dedicated signaling.

Certainly, in the actual application, there is another manner of delivering the first PCI list, which is not specifically limited in the embodiment of the present invention.

S205: The user equipment queries the PCI of the strongest cell in the first PCI list.

S206a: When the PCI of the strongest cell is queried in the first PCI list, the user equipment determines that the strongest cell is a campable cell, and continues to read the system message of the strongest cell to complete cell selection.

Specifically, when the user equipment queries the first PCI list to determine that the strongest cell is a cell in the cluster private network in which it is currently located, the most strong cell is determined to be a campable cell, and then, the broadcast channel in the strongest cell The line reads the above system message, and judges whether the strongest cell is suitable for camping according to the system message and the S criterion. If yes, it stays on the strongest cell to complete the cell selection; otherwise, selects the second strong cell to make the decision, and so on. Until the location of the appropriate resident cell is selected.

S206b: When the PCI of the strongest cell is not queried in the first PCI list, the user equipment determines that the strongest cell is a non-resident cell, and terminates the cell selection.

Specifically, when the user equipment queries the first PCI list to determine that the strongest cell is not the cell in the cluster private network in which it is currently located, the most strong cell is determined to be a non-resident cell, and at this time, the cell selection process is terminated, Then continue to read the system message of the strongest cell, but select the second strong cell to make the decision, and so on, until the cell location that is suitable for camping is selected.

In an embodiment, the user equipment may also determine that the non-resident cell, such as the strongest cell corresponding frequency point, is determined to be an unavailable frequency point, and add it to the blacklist. Then, when the cell search is performed next time, it is no longer Search for unavailable frequency points, that is, the frequency points in the blacklist, reducing the power consumption of the device caused by unnecessary search. If the cell corresponding to the frequency point in the blacklist joins the cluster private network, the user equipment removes the frequency from the blacklist.

The method of selecting the above cell on the user equipment side will be described below.

FIG. 3 is a schematic flowchart of a method for performing cell selection by a user equipment side according to an embodiment of the present invention. Referring to FIG. 3, the method includes:

S301: After performing a cell search, obtain a PCI of the strongest cell;

S302: Query the PCI of the strongest cell in the first PCI list sent by the base station, where the first PCI list includes PCIs of all cells in the cluster dedicated network;

S303a: When the PCI of the strongest cell is queried in the first PCI list, the strongest cell is determined to be a campable cell, and the system message of the strongest cell is continuously read to complete the cell selection.

S303b: When the PCI of the strongest cell is not queried in the first PCI list, the strongest cell is determined to be a non-resident cell, and the cell selection is terminated.

In an embodiment, after S303b, the method may further include: determining a frequency point corresponding to the strongest cell as an unavailable frequency point, so that the unavailable frequency point is no longer searched when the cell search is performed again.

In an embodiment, after the step of determining the frequency point corresponding to the strongest cell as the unavailable frequency point, the method may further include: when the strongest cell joins the cluster private network, the frequency corresponding to the strongest cell is used. Changed from the unavailable frequency point to the available frequency point.

In an embodiment, the method may further include: when the user equipment performs initial cell selection, performing all available frequency point scanning on the cluster private network to determine the strongest cell; obtaining the system message of the strongest cell, where the strongest The system message of the cell carries the first PCI list.

Next, a method of selecting the above cell at the base station side will be described.

FIG. 4 is a schematic flowchart of a method for performing cell selection by a base station side according to an embodiment of the present invention. Referring to FIG. 4, the method includes:

S401: When the cluster private network is created, expanded, or reduced, the OAM entity reports the PCI of all the cells under its jurisdiction;

S402: Receive a first PCI list from the OAM entity, where the first PCI list includes PCIs of all cells in the cluster private network;

S403: Send a first PCI list to the user equipment, where the first PCI list is used for the user. The device performs cell selection.

In an embodiment, the step of sending the first PCI list to the user equipment in S403 includes: carrying the first PCI list in a system message and sending the information to the user equipment.

The method for cell handover provided by the embodiment of the present invention is described below in conjunction with the foregoing system.

FIG. 5 is a schematic flowchart of a method for performing cell handover by a cluster-dedicated communication system according to an embodiment of the present invention. Referring to FIG. 5, the method includes:

S501: The source base station sends a measurement configuration to the user equipment, where the measurement configuration carries a first PCI list including all the cells in the cluster private network where the source base station is located;

S502: The user equipment performs cell measurement according to the measurement configuration, and obtains a PCI of the strongest cell.

S503: The user equipment queries the PCI of the strongest cell in the first PCI list.

S504a: When the PCI of the strongest cell is queried in the first PCI list, the user equipment continues to read the system message of the strongest cell.

S505a: The user equipment carries the system message of the strongest cell in the measurement report and reports it to the source base station;

S506a: The source base station initiates a cell handover according to the measurement report, and switches the user equipment to the strongest cell.

S504b: When the PCI of the strongest cell is not queried in the first PCI list, the user equipment terminates the system message of reading the strongest cell, and terminates the cell selection.

In an embodiment, the user equipment can also add the corresponding frequency of the strongest cell that cannot be camped to the blacklist. Then, when the cell search is performed next time, the frequency in the blacklist is not searched again, and the unnecessary search is reduced. The power consumption of the device.

In another embodiment, when the base station performs the ANR configuration, the user equipment may perform S501 to S505a, and report the strongest cell located in the cluster private network to the base station, where the base station determines that the strongest cell is not in the second PCI list (service) After the neighboring cell PCI list of the cell is added, the strongest cell PCI is added to the second PCI list to complete the configuration of the ANR.

It can be seen from the foregoing that, in the method for cell selection provided by the embodiment of the present invention, the user equipment stores the first PCI list delivered by the base station (including the PCI of all cells in the trunking private network), and then the user equipment performs the cell search. After obtaining the PCI of the strongest cell, the PCI of the strongest cell is queried in the first PCI list, that is, whether the cell is the cell of the cluster private network where the base station is located, and if so, the first PCI list is queried. When the PCI of the strongest cell is determined, the strongest cell is determined to be a campable cell, and the system message of the strongest cell is continuously read, and the camping decision is performed to complete the cell selection; if not, the first PCI list is not queried. When the PCI of the strongest cell is reached, the strongest cell is determined to be a non-resident cell, and the cell selection is directly terminated without further camping decision. Thus, the user equipment is prevented from being unable to be normal due to the selection of the non-interworking cell. The problem of communication ensures the reliability of the communication of the user equipment in the cluster private network, and improves the efficiency of subsequent activities such as camping, handover, and ARN configuration, while avoiding The user device reads the system message of the cell caused by non-interworking unnecessary power consumption.

Embodiment 2:

At present, the implementation of the ANR has been stipulated in the 3GPP protocol. In the initial network construction, there is no neighbor relationship in the neighbor relationship list. All the handover target cells reported by the user equipment are missed neighbors, and the base station guides the user. The device reports the neighboring cell PCI and schedules an appropriate idle time to allow the UE to read the E-UTRAN Cell Global Identifier (ECGI) of the new cell and add it to the neighbor list.

The following is a specific example to analyze the problems existing in the prior art ANR configuration.

For example, the base station serves the cell A, and the base station notifies the user equipment to perform the neighbor cell measurement.

Step 1: The user equipment sends a measurement report of the cell B to the base station, where the measurement report includes the PCI of the cell B, but does not include the ECGI;

Step 2: The base station notifies the user equipment to use the newly discovered PCI to read the ECGI, TAC, and PLMN ID of the cell B.

At this point, the base station may need to schedule the appropriate idle time to allow the user equipment to read these messages. This may cause the user equipment to take a long time to read these system messages.

Step 3: After the user equipment obtains the ECGI, TAC, and PLMN ID of the cell B, the user equipment reports the information to the serving cell base station;

Step 4: The serving cell base station determines whether to add the cell B to the neighboring cell relationship based on the neighboring cell neighboring cell policy.

It can be seen from the above that if the user equipment wants to read the information such as the ECGI of the cell B, it must wait for the base station to schedule an appropriate idle time. Then, in the process of performing cell handover, the cell B is a missed cell, and the user equipment wants to switch. To the cell B, it is necessary to read the information such as the ECGI of the cell B, that is, it has to wait for the scheduling of the base station, which takes a long time, and may cause the handover to be performed in time and is easy to drop.

Therefore, in order to solve the above problem, the embodiment of the present invention provides an ANR configuration method, and the general idea is as follows:

The user equipment searches for the strongest cell by performing cell search. When it is determined that the strongest cell is not in the second PCI list (the neighboring cell PCI list of the serving cell), the system message of the strongest cell is directly read, and the system is read. The message is carried in the measurement report and reported to the serving base station for the serving base station to perform ANR configuration.

In this way, when determining that the strongest cell is not in the second PCI list, the user equipment directly reads the system message of the strongest cell, without first reporting the PCI of the strongest cell to the base station, waiting for the base station to perform the scheduling instruction, and then reading the strongest cell. The system message, in this way, avoids waiting for the time indicated by the base station to be too long, and can not obtain the above system message in time, which greatly shortens the time for reading the system message, thereby enabling fast switching and reducing the occurrence of dropped calls during the cell handover process. .

The above scheme will be described in detail below.

The embodiment of the present invention provides a wireless communication system, which may be located in a public mobile communication network, such as an LTE network, a UTMS network, or the like; or may be located in a cluster dedicated network, such as an IOPS network, and is not specific to the embodiment of the present invention. limited.

FIG. 6 is a schematic structural diagram of a system of a wireless communication system according to an embodiment of the present invention. Referring to FIG. 6, the system includes: a user equipment 61 and a base station 62.

According to the embodiment of the present invention, the user equipment 61 is configured to perform cell search according to the measurement configuration sent by the base station 62 to obtain the PCI of the strongest cell, and determine that the strongest cell is not in the second PCI list according to the PCI of the strongest cell (service) After the neighboring cell PCI list of the cell, the system message of the strongest cell is directly read; the system message is carried in the measurement report and reported to the base station 62, wherein the system message is used by the base station 62 to configure the ANR;

The base station 62 is configured to receive a measurement report from the user equipment 61, where the measurement report carries a system message of the strongest cell measured by the user equipment 61; when determining that the strongest cell PCI is not in the second PCI list based on the second PCI list When the strongest cell satisfies the base station neighboring cell decision policy, the PCI of the strongest cell is added to the second PCI list.

The ANR configuration method provided by the embodiment of the present invention will be described below in conjunction with the above wireless communication system.

FIG. 7 is a schematic flowchart of a method for performing ANR configuration in a wireless communication system according to an embodiment of the present invention. Referring to FIG. 7, the method includes:

S701: The user equipment performs cell search according to the measurement configuration sent by the base station, and obtains the PCI of the strongest cell.

Specifically, the base station sends a measurement configuration to the user equipment, where the measurement configuration carries a neighbor list of the serving cell of the user equipment, and after receiving the measurement configuration, the user equipment starts to perform cell measurement to obtain the PCI of the strongest cell.

S702: The user equipment determines, according to the PCI of the strongest cell, that the strongest cell PCI is not in the second PCI list, and directly reads the system message of the strongest cell.

Specifically, the user equipment queries the PCI of the strongest cell in the second PCI list, and if the PCI of the strongest cell is queried, reports the PCI of the strongest cell to the base station; if not, the user equipment directly reads the strongest cell. System message without first reporting the PCI of the strongest cell to the base station, waiting for the base The station scheduling indication reads the system message of the strongest cell again, so that the system message cannot be obtained in time due to waiting for the time indicated by the base station to be too long.

Here, when the user equipment reads the system message of the strongest cell, it only needs to read the information that the base station wants to obtain information (including ECGI, TAI, PLMN ID, etc.), and does not need to read all system messages. These system messages that are read by the user device can be referred to as valid system messages.

S703: The user equipment carries the system message in the measurement report and reports it to the base station.

Here, in actual application, when the user equipment only reads the valid system message, the system message carried in the measurement report is the valid system message acquired in the strongest cell.

S704: The base station receives a measurement report from the user equipment.

S705: When the base station determines, according to the second PCI list, that the strongest cell PCI is not in the second PCI list, and the strongest cell satisfies the base station neighboring cell decision policy, the base station adds the strongest cell PCI to the second PCI list.

Specifically, since the second PCI list is managed by the base station, and the second PCI list information retained by the user equipment may not be the latest, a situation may be different from the current second PCI list of the base station, so, in order to improve the ANR configuration. Accuracy and efficiency, after receiving the measurement report, the base station still needs to reconfirm whether the PCI of the strongest cell is in the second PCI list, and if so, perform subsequent processes such as handover decision; if not, according to the neighboring cell of the base station The decision policy determines whether the strongest cell PCI is to be added to the second PCI list, and the base station adds the strongest cell PCI to the second PCI list only when the strongest cell satisfies the base station decision policy, and the updated second PCI List for subsequent cell switching use.

It should be noted that the base station neighboring cell decision policy is a prior art, for example, the strongest cell is a cell that is allowed to join, or the strongest cell is suitable for the user equipment to reside, and the like, which is not specifically limited in the embodiment of the present invention.

The above ANR configuration method will be described below on the user equipment side.

FIG. 8 is a schematic flowchart of a method for performing ANR configuration on a user equipment side according to an embodiment of the present invention; Figure, see Figure 8, the method includes:

S801: Perform cell search according to the measurement configuration delivered by the base station, and obtain the PCI of the strongest cell.

S802: Determine, according to the PCI of the strongest cell, that the PCI of the strongest cell is not in the second PCI list, and directly read the system message of the strongest cell.
