In a scenario where a network cell is deployed, the operator requires that the network subscription user of the restricted network cell can preferentially access the network.

For a restricted network cell, since the non-subscribed users of the network also have the right to camp on the network, the restricted network cell information cannot be placed in the dedicated message, and the restricted cell is configured in the normal neighbor list. in. The current neighboring area configuration scheme needs to adopt the traditional manual network configuration method to configure the restricted network cell neighboring area in the neighboring cell list of all relevant cells. Since the restricted network cell can only be placed in the macro network neighbor list, the UE (User Equipment) can only use the traditional S/R criteria to trigger cell measurement and reselection.

The carrier frequency information, the scrambling code, the physical cell identifier Cell ID of the neighboring cell, the RSRP (Reference Signal Receiving Power) of the restricted network cell, and the RSSI (Received Signal Strength Indication).

104. The NAS process of the user equipment and the serving cell performing the NAS signaling request.

The method in the embodiment of the present invention can implement the normal service of the UE, and can detect the neighboring restricted network cell in time, and measure the discovered restricted network cell, which not only improves the UE. Access rate, and improve the quality of communication services.

FIG. 2 is a flowchart of a method for measuring a restricted network cell according to an embodiment of the present invention. The interaction subject of the embodiment is a UE (User Equipment) and a base station, and the serving cell covered by the base station may be a macro cell. Referring to FIG. 2, this embodiment uses a service flow when the UE enters the serving cell as an example. The embodiment specifically includes:

201. The UE initiates NAS signaling for the first time in a serving cell covered by the base station.

In this embodiment, only the NAS signaling is used as an example of LAU signaling, and the LAU needs to establish an RRC (Radio).

Resource Control, Radio Resource Control Protocol) The following steps 202-204 are procedures for establishing an RRC connection.

When the UE enters a serving cell, the Cell ID of the serving cell is updated, and after receiving the system message sent by the base station, the UE first initiates NAS signaling for the first time in the serving cell covered by the base station. Initiate NAS signaling.

202. The base station establishes a DCH (Dedicated Channel) channel, and sends an RRC connection setup response to the UE. 203. The UE receives an RRC connection setup response, and establishes an RRC connection with the base station.

204. The UE sends an RRC connection setup complete message to the base station.

Steps 202-204 are the process of establishing an RRC connection, which is the same as the prior art, and is not described in this embodiment.

205. The base station sends a neighboring subscriber group CSG measurement control message to the UE.

In this embodiment, when the base station receives the RRC connection setup complete message sent by the UE, the base station sends a CSG measurement control message to the UE, where the CSG measurement control message is specifically used to instruct the UE to query the UE according to the physical cell identifier of the serving cell covered by the base station. The saved neighboring subscriber group list is measured, and the measurement is performed according to the queried restricted network cell information.

After the base station receives the NAS-initiated NAS request and establishes an RRC connection according to the NAS request, the control UE measures the known restricted network cell according to the saved first restricted network cell information, so that the UE can discover the neighboring The restricted network cell, and initiates a reselection after the UE enters the idle Idle state to obtain a better communication service.

The UE receives the CSG measurement control message sent by the base station, and determines whether the neighboring subscription group list stored by the UE includes the physical cell identifier of the serving cell covered by the base station;

If yes, go to step 207;

If no, go to step 210;

It should be noted that the neighboring subscriber group list is used to save the physical cell identifier and the physical cell identifier of the restricted network cell corresponding to the physical cell identifier.

In this embodiment, when it is determined that the neighboring subscriber group list stored by the UE includes the physical cell identifier of the serving cell covered by the base station, the neighboring subscriber group list includes the restricted network cell corresponding to the serving cell, When it is determined that the locally stored neighboring subscriber group list does not include the physical cell identifier of the serving cell covered by the base station, it indicates that the restricted subscriber group list does not include the restricted network cell corresponding to the serving cell.

If the UE has accessed or camped on the certain cell, and the neighbor cell list of the cell is known and saved, the UE saves the physical cell identifier of the serving cell covered by the base station in the form of a neighboring subscriber group list. The physical cell identifier of the corresponding restricted network cell, in this embodiment, when the UE receives the CSG measurement control message sent by the serving cell, and determines, according to the physical cell identifier of the serving cell covered by the base station, whether the UE saves the service. A restricted network cell corresponding to the cell.

207. Obtain a scrambling code of the restricted network cell corresponding to the physical cell identifier of the serving cell that is covered by the base station, and perform measurement according to the scrambling code to obtain second restricted network cell information.

The measurement based on the scrambling code is prior art and will not be described again.

In this embodiment, the second restricted network cell information is measured according to the scrambling code of the restricted network cell corresponding to the physical cell identifier of the serving cell that is covered by the base station, and the second restricted network cell information may include: Physical cell identifier, adjacent closed subscriber group identifier CSG ID, carrier frequency information, scrambling code, physical cell identifier of neighboring cell Cell ID, RSRP (Reference Signal Receiving Power), RSSI (Received Signal Strength Indication), and the like.

208. The UE sends the acquired second restricted network cell information to the base station.

The second restricted network cell information may be sent to the base station in the form of a measurement report.

The serving cell may use the received second restricted network cell information to perform a handover decision, which is not described in the present invention.

209. The base station configures the neighbor list according to the obtained second restricted network cell information.

In this embodiment, the second restricted network cell information carries the restricted network cell information measured by the user equipment, and the base station uses the restricted network cell information measured by the user equipment, and the carrier frequency information and the scrambling code are the same, and the physical cell identifier is different. The restricted network cells are merged into one virtual neighboring cell, and the virtual neighboring cell is configured in the neighboring cell list. In practice, this configuration can be performed by the serving cell RNC (Radio Network Controller). For example, Table 1 is a schematic table of the merge method of virtual neighbors.

Table 1

In the prior art, the physical cell identifier of all the restricted network cells needs to be configured in the neighboring cell list of each macro cell. Because the neighboring cell resources are insufficient, the restricted network cell may be missed, and the configuration workload is very high. Large, it is necessary to determine how many restricted network cells are around each macro cell, and configure the restricted network cells one by one. The present embodiment is The constrained network frequency information and the restricted network cell with the same scrambling code and different physical cell identifiers achieve the purpose of saving neighboring resources and avoiding missed allocation.

210. A NAS process in which the UE and the base station perform the NAS signaling request.

In this embodiment, the NAS request is used as an example for the LAU request. In this step 210, the NAS process is specifically a LAU process, and the LAU is consistent with the LAU process in the prior art, and details are not described herein again. .

When the NAS process is initiated, the base station controls the UE to perform the measurement of the neighboring subscriber group, and can timely discover the neighboring restricted network cell while maintaining the normal communication of the service. After the NAS process of the UE is performed, the UE enters the Idle state and resides in the serving cell covered by the base station. Referring to FIG. 2b, the embodiment further includes:

211, when the UE enters the Idle state and the neighboring subscriber group list saved by the UE includes the physical cell identifier of the serving cell covered by the base station, step 212 is performed;

Preferably, since the determination of step 211 has been performed in step 206, the UE may save the determination result after the judgment of step 206 is completed, and at step 211, it is determined according to the determination result that step 212 or 215 is performed.

If yes, go to step 212;

If no, go to step 215;

The UE resides in the serving cell covered by the base station, and is generally in the idle Idle state when no service request is made, or the UE camps on the serving cell covered by the base station after the UE completes the service flow in the serving cell. In, it enters the Idle state.

The UE obtains the scrambling code of the restricted network cell corresponding to the physical cell identifier of the serving cell that is covered by the base station, and performs measurement according to the scrambling code to obtain the second restricted network cell information, and step 218 is performed;

This step 212 is the same as step 207, and details are not described herein again.

Preferably, when it is determined that the neighboring subscription group list saved by the UE includes the physical cell identifier of the serving cell covered by the base station, step 212 is performed. Since the step 207 is a measurement performed when the user equipment initiates the service flow, the user equipment may experience a missed measurement or other measurement error during the measurement. Therefore, in this embodiment, when the user equipment enters the idle state, The re-measurement in step 212 is performed to ensure the accuracy of the measurement of the user equipment and improve the probability of success of the subsequent re-election process.

In another embodiment, when it is determined that the physical cell identifier of the serving cell covered by the base station is included in the neighboring subscriber group list saved by the UE, step 212 may not be performed, but only according to the measurement obtained in step 207. The second restricted network cell information performs a subsequent reselection process.

213. Determine, according to the second restricted network cell information and the restricted network cell list that the user equipment is allowed to access, whether the restricted network cell information in the restricted network cell list is updated, when the restricted network cell information has When updating, the user equipment sends the updated restricted network cell information to the base station; The same user may belong to multiple restricted network cells, and the UE maintains a list of restricted network cells that belong to the restricted network cell, that is, a list of CSG IDs, which may include multiple CSG IDs, and each CSG ID identifies a restricted one. The network cell, the restricted network cell corresponding to other CSG IDs outside the CSG ID list, is inaccessible to the UE. And each restricted network cell broadcasts a CSG ID, and members of the closed subscriber group identified by the CSG ID can access the restricted network cell. Determining, by the measured second restricted network cell information, whether the restricted network cell information in the restricted network cell list is updated, and once updated, the user equipment actively initiates an RRC connection request, and the updated restricted network cell information is used as a measurement report. The form is sent to the serving cell.

214. The base station configures the neighbor list according to the updated restricted network cell information.

In this embodiment, the step 217 is the same as the step 209, and details are not described herein again.

215. The UE performs a full-band CSG search in a registered PLMN (Public Land Mobile Network) for a first preset duration.

In this embodiment, since the UE does not save the restricted network cell corresponding to the physical cell identifier of the serving cell covered by the base station, the base of the restricted network cell is not found, so the search needs to be performed in the full frequency band. The UE is in the Idle state, and the search for the full frequency band does not affect the normal service flow of the UE, and the neighboring restricted network cell can be known according to the search of the full frequency band, which is only based on the prior art. The signal strength of the serving cell triggers the search, greatly expanding the scope of the search.

Preferably, the UE performs the search by using the CSG search timer T1, and the timeout period of the T1 is the first preset duration t1. When the CSG search timer T1 expires or overflows, the full frequency band is triggered. Search and re-time.

216. The UE determines to search for the restricted network cell, and records the searched third restricted network cell information.

The third restricted network cell information is obtained by performing full-band search in the Idle state of the UE. It should be noted that, when performing full-band search, multiple network cell information may be acquired, except for the third aspect of the present invention. In addition to the restricted network cell information, other network cell information may be included. In this embodiment, when the network cell is searched, only the restricted network cell is concerned, where the restricted network cell refers to the UE allowing access. The restricted network cell, that is, the acquired restricted network cell needs to be a restricted network cell in the restricted network cell list held by the UE, just because the UE allows access to the restricted network cell in the restricted network cell list. , Search and Record will be able to serve the subsequent re-election process.

This embodiment is described by taking the example that the UE searches for the restricted network cell in the full-band search process. When the UE does not search for the restricted network cell within the first preset duration, step 215 is performed again.

217. When the UE obtains the third restricted network cell information, the neighboring subscription group search is performed in the full frequency range every second preset duration, where the first preset duration is less than the second preset duration;

In this embodiment, if the restricted network cell is searched within the first preset time period, the UE searches for the timer T1. The length adjustment is longer. The second preset duration greater than the first preset duration is used as the search interval, and the CSG search is performed every second preset duration, which can reduce the UE power consumption.

218. The UE initiates reselection to the restricted network cell according to the CSG reselection criterion.

In this embodiment, the restricted network cell may be the restricted network cell learned by the searching process of steps 215-217, or may be the restricted network cell saved in the neighboring subscriber group list determined in step 211. When determining, according to the restricted network cell list saved by the UE, that there is a restricted network cell in the vicinity of the serving cell that allows the UE to access as a subscription user, in order to obtain a better communication service, the restricted network cell that the UE is allowed to access may initiate reselection. .

219. The UE determines whether the reselection is successful.

If yes, end; if no, go to step 220;

The UE performs measurement on the restricted network cell in the third restricted network cell information that is searched for every third preset duration. The third preset duration is less than the first preset duration, and the first preset duration arrives. When the measurement is stopped, step 215 is resumed.

In the case that the third restricted network cell information is searched, in the process of performing cell reselection by the UE, congestion may occur or the restricted network cell does not satisfy the condition on the reselection criterion, so that the UE reselection is unsuccessful. If the measurement is inaccurate, the searched restricted network cell is measured by using a shorter third preset duration to obtain more accurate third restricted network cell information without performing full-band search. When the third restricted network cell information is obtained, the UE may perform reselection according to the third restricted network cell information. After the multiple measurements are taken until the first preset duration is reached, the reselection is still unsuccessful, and the searched restricted network cell is considered to be unsuitable for the UE to perform reselection. To obtain more restricted network cells for reselection.

In the case that the second restricted network cell information is obtained according to the measurement, in the process of performing cell reselection by the UE, congestion may also occur or the restricted network cell does not satisfy the condition on the reselection criterion, so that the UE is heavy. If the selection is unsuccessful, the measurement may be considered inaccurate, and the measurement is performed again according to the first restricted network cell information, and the reselection is performed according to the measured result.

Once the UE reselects successfully, the UE leaves the serving cell and enters the restricted network cell. When the UE initiates a service process in the reselected restricted network cell, the specific process is as shown in steps 201-212. . Each time the UE enters a reselected serving cell, it can take measurements when the business process is initiated for the first time, and search or measure while camping. The embodiment of the present invention only takes the service flow performed by the UE in one serving cell and the discovery process of the restricted network cell in the camping process as an example, and the service flow and the resident process performed by the UE after the reselection are performed. The process is the same as that of the embodiment of the present invention, and will not be described again.
