detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As described in the background, in the re-establishment scenario, if the measurement configuration of the UE and the eNB is inconsistent, the eNB may be incompatible with the current measurement configuration of the UE when the initial measurement configuration is delivered, that is, the same carrier frequency corresponds to different measurement objects. The RRC connection reconfiguration fails, and the re-establishment is initiated again. specifically:

If the radio link fails and the integrity check fails, the UE uses the measurement configuration information that is currently in effect. That is, when the UE initiates the RRC connection re-establishment, the MAC (Medium Access Control) and PHY (Physical Layer) are reset. Layer) configuration, but does not reset the RRC layer configuration, the measurement configuration in effect is saved.

In the scenario of the radio link failure and the integrity protection check failure, the RRC connection reestablishment is successful, and after the RRC connection is restored, the eNB sends the measurement task to the UE through the RRC connection reconfiguration message, and normally receives the UE from the UE. The RRC connection reconfiguration complete message. If the RRC connection reconfiguration complete message is not received but the RRC connection reestablishment message is received, there are three cases:

1) Before receiving the RRC connection reconfiguration message, the UE detects the uplink out-of-synchronization and initiates the RRC connection reestablishment. The RRC re-establishment request message carries the re-establishment cause as other failures; the UE adopts the original measurement configuration;

2) The UE receives the RRC connection reconfiguration message, and sends an RRC connection reconfiguration complete message to the eNB, but does not receive the ACK response of the message, initiates an RRC connection re-establishment, and the RRC re-establishment request message carries the re-establishment reason as other Failure; the UE adopts the measurement configuration included in the received RRC connection reconfiguration message;

3) The UE receives the RRC connection reconfiguration message, but the integrity check fails, and the RRC connection re-establishment is initiated. The RRC re-establishment request message carries the re-establishment cause as other failures; the UE adopts the original measurement configuration.

When the RRC layer of the RRC layer receives the RRC connection reestablishment message, the reason for the reestablishment is that the eNB cannot determine whether the current measurement configuration is valid in the UE, and the measurement configuration of the UE side and the eNB side is inconsistent. For example, in the following three scenarios:

1) The eNB sends a measurement task (MeasId=1, MeasObjectId=1 (Freq1), ReportConfigId=1) through the RRC connection reconfiguration message, and the UE receives the RRC connection reconfiguration message. After the configuration takes effect, the radio link is detected. If the failure occurs, the re-establishment is directly initiated, and the eNB receives the RRC connection re-establishment before receiving the RRC reconfiguration complete message, and the re-establishment cause is otherFailure. The eNB considers that the UE does not take effect in this measurement configuration, performs RRC connection reestablishment, and deletes the effective measurement configuration (excluding MeasId=1, MeasObjectId=1 (Freq1), ReportConfigId=1). After the RRC connection reestablishment is completed, the RRC connection reconfiguration message is sent, and the RRC connection reconfiguration message includes a new initial measurement configuration (MeasId=1, MeasObjectId=2 (Freq1), ReportConfigId=1); the UE receives the RRC connection reconfiguration. When the message is configured for measurement, it is verified that one carrier frequency corresponds to different measurement objects. If the RRC connection reconfiguration fails, the RRC connection re-establishment is initiated again.

2) The eNB sends a delete measurement task (MeasId=1, MeasObjectId=1(Freq1), ReportConfigId=1) through the RRC connection reconfiguration message, and the UE side does not receive the RRC connection reconfiguration message, and detects that the radio link fails to be initiated. RRC connection re-establishment. The eNB receives the RRC connection re-establishment message and receives the RRC connection re-establishment message, and the re-establishment cause is otherFailure. The eNB considers that the UE is valid for the current measurement configuration and performs RRC connection reestablishment. After the RRC connection reestablishment is completed, the RRC connection reconfiguration message is sent, and the RRC connection reconfiguration message includes the eNB deleting the valid measurement configuration (excluding MeasId=1, MeasObjectId=1 (Freq1), ReportConfigId=1), and issuing a new one. Initial measurement configuration (MeasId=1, MeasObjectId=2(Freq1), ReportConfigId=1); when the UE receives the RRC connection reconfiguration message for measurement configuration, it verifies that one carrier frequency corresponds to different measurement objects, and does not comply with the protocol specification. The RRC connection reconfiguration fails, and the RRC connection re-establishment is initiated again.

3) The eNB sends a delete measurement task (MeasId=1, MeasObjectId=1 (Freq1), ReportConfigId=1) through the RRC connection reconfiguration message, and the UE receives the RRC connection reconfiguration message, but the integrity protection check fails. The measurement configuration is not in effect. The eNB receives the RRC connection re-establishment before receiving the RRC reconfiguration complete message, and the re-establishment cause is otherFailure. The eNB considers that the UE is valid for the current measurement configuration, performs RRC connection reestablishment, and the eNB deletes the effective measurement configuration (excluding MeasId=1, MeasObjectId=1 (Freq1), ReportConfigId=1). After the RRC connection reestablishment is completed, the RRC connection reconfiguration message is sent, and the RRC connection reconfiguration message includes a new initial measurement configuration (MeasId=1, MeasObjectId=2 (Freq1), ReportConfigId=1); the UE receives the RRC connection reconfiguration. When the message is configured for measurement, it is verified that one carrier frequency corresponds to a different measurement object, and if the RRC connection reconfiguration fails according to the protocol specification, the re-establishment is initiated again.

To this end, the present invention provides a processing method for RRC measurement reconfiguration.

Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of a first embodiment of a method for processing RRC measurement reconfiguration according to the present invention.

The processing method of the RRC measurement reconfiguration includes the following steps:

Step S101, receiving an RRC connection reconfiguration message from the eNB.

The RRC connection reconfiguration message triggers a scenario, which may be a measurement reconfiguration caused by intra-system handover, inter-system handover, or UE mobility.

Step S102: Reconfigure the local measurement configuration according to the RRC connection reconfiguration message.

That is, the UE includes a local measurement configuration before performing reconfiguration, and a local measurement configuration reconfigured according to the RRC connection reconfiguration message. For the sake of distinction, the measurement configuration used before reconfiguration is recorded as the first measurement configuration; the measurement configuration used after reconfiguration is recorded as the second measurement configuration. That is, the above steps may also be expressed as: replacing the local measurement configuration from the first measurement configuration to the second measurement configuration according to the RRC connection reconfiguration message.

Step S103, when the reconfiguration is completed, the RRC connection reconfiguration complete message is sent to the eNB.

Step S104: Determine whether an ACK response of the RRC connection reconfiguration complete message is received within a preset time after the RRC connection reconfiguration complete message is sent; if yes, execute step S105; if no, execute step S106.

In step S105, it is determined that the flow of the RRC connection reconfiguration ends.

That is, the RRC connection reconfiguration message triggers a normal process and ends successfully.

Step S106, the local measurement configuration is rolled back to the measurement configuration before the reconfiguration.

In step S107, an RRC connection reestablishment request message is sent to the eNB.

When the RRC connection reestablishment request is issued, the UE considers that the current RRC connection reconfiguration fails. That is, the current RRC connection reconfiguration message fails to trigger a complete process, and ends halfway and sends an RRC connection reestablishment request message to the eNB.

The processing method of the RRC measurement reconfiguration provided by the embodiment is that when the radio link fails, the RRC connection reconfiguration complete message is not successfully sent to the eNB, and the ACK of the RRC connection reconfiguration complete message is not received. response. Then the RRC connection reestablishment between the UE and the eNB will be caused. Since the solution is configured to roll back the measurement configuration in the UE to the measurement configuration before the reconfiguration, and the pre-reconfiguration measurement configuration is the previously successfully performed measurement configuration, it can be ensured that the corresponding measurement configuration also exists in the eNB. Therefore, the UE and the eNB are prevented from failing to reestablish the RRC connection due to different measurement configurations during the RRC connection reestablishment.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart diagram of a second embodiment of a method for processing RRC measurement reconfiguration according to the present invention.

On the basis of the first embodiment, before step S102, the method further includes:

Step S108: Perform an integrity protection check on the RRC connection reconfiguration message; if the verification fails, step S107 is performed; if the verification is successful, step S103 is performed.

Since the received RRC connection reconfiguration message may be broken and cannot pass the integrity protection check, the UE considers that the current RRC connection reconfiguration fails, and sends an RRC connection reestablishment request message to the eNB.

The RRC measurement reconfiguration processing method provided in this embodiment, in the scenario of the integrity protection check failure scenario, after the RRC connection reconfiguration failure occurs, the RRC connection reestablishment between the UE and the eNB is caused, because the UE does not The reconfiguration of the local measurement configuration, while the current local measurement configuration is a successful reconfiguration configuration, can ensure that there is also a corresponding measurement configuration in the eNB. Therefore, the UE and the eNB are prevented from failing to reestablish the RRC connection due to different measurement configurations during the RRC connection reestablishment.

Please refer to FIG. 3. FIG. 3 is a schematic flowchart diagram of a third embodiment of a method for processing RRC measurement reconfiguration according to the present invention.

On the basis of the first embodiment, before step S101, the method further includes:

In step S109, the wireless link is detected. If the wireless link fails, step S107 is performed. If the wireless link fails, step S101 is performed.

Because the radio link failure may occur during the process of waiting for the received RRC connection reconfiguration message, for example, the uplink fails, the UE considers that the current RRC connection reconfiguration fails, and sends an RRC connection reestablishment request message to the eNB.

Referring to FIG. 4, FIG. 4 is a schematic flowchart diagram of a fourth embodiment of a method for processing RRC measurement reconfiguration according to the present invention.

In step S201, the evolved base station eNB sends an RRC connection reconfiguration message to the UE, and reconfigures the local measurement configuration according to the RRC connection reconfiguration message.

That is, the eNB includes a local measurement configuration before performing reconfiguration, and a local measurement configuration reconfigured according to the RRC connection reconfiguration message. For the sake of distinction, the measurement configuration used before reconfiguration is recorded as the first measurement configuration; the measurement configuration used after reconfiguration is recorded as the second measurement configuration. That is, the above steps may also be expressed as: replacing the local measurement configuration from the first measurement configuration to the second measurement configuration according to the RRC connection reconfiguration message.

Step S202, it is determined whether the RRC connection reestablishment request message initiated by the UE is received before receiving the RRC connection reconfiguration complete message; if yes, step S203 is performed.

When the radio link fails or the integrity check fails, the UE does not issue an RRC connection reconfiguration complete message, or the UE issues an RRC connection reconfiguration complete message, but the eNB does not receive the situation. Then, at this time, the eNB will receive an RRC connection reestablishment message from the UE.

Step S203, the local measurement configuration is rolled back to the measurement configuration before the reconfiguration, and the RRC connection reestablishment message is sent to the UE.

The RRC measurement reconfiguration processing method provided in this embodiment, in the scenario of a radio link failure and an integrity check failure, after the RRC connection reconfiguration failure occurs, the RRC connection reestablishment between the UE and the eNB is caused, The scheme reduces the local measurement configuration in the eNB to the measurement configuration before reconfiguration, and the measurement configuration is a configuration that is successfully reconfigured before, so that the corresponding measurement configuration is also present in the UE. Therefore, the UE and the eNB are prevented from failing to reestablish the RRC connection due to different measurement configurations during the RRC connection reestablishment.

Referring to FIG. 5, FIG. 5 is a schematic flowchart diagram of a fifth embodiment of a method for processing RRC measurement reconfiguration according to the present invention.

The processing method of the RRC measurement reconfiguration includes:

Step S301, the first measurement configuration is sent to the UE by using the first RRC connection reconfiguration message.

When the eNB sends the first measurement configuration to the UE, the eNB will reconfigure the local measurement configuration on the eNB side according to the first measurement configuration, so that the local measurement configuration on the eNB side and the local measurement on the UE side after the UE performs the first measurement configuration. The configuration is the same.

Step S302, determining whether the RRC connection reestablishment request message initiated by the UE is received before receiving the RRC connection reconfiguration complete message; if yes, executing step S303.

When the radio link fails or the integrity check fails, the UE may not issue an RRC connection reconfiguration complete message; or the UE issues an RRC connection reconfiguration complete message, but the eNB does not receive the situation. Then, at this time, the eNB will receive an RRC connection reestablishment message from the UE. When the UE considers that the RRC connection reconfiguration fails, an RRC Connection Reestablishment Request message will be initiated.

Step S303, the RRC connection reestablishment message is sent to the UE.

The difference from the fourth embodiment is that the eNB does not perform the eNB-side local measurement configuration rollback operation after receiving the RRC connection reestablishment request message from the UE, but directly sends an RRC connection reestablishment message to the UE.

In step S304, it is determined whether an RRC connection reestablishment completion message is received, and if yes, step S305 is performed.

Step S305: The second RRC connection reconfiguration message is sent to the UE to delete all measurement configurations and deliver the second measurement configuration.

After the RRC connection reestablishment is successfully performed, the second RRC connection reconfiguration is performed. Since the eNB side local measurement configuration fallback operation is not performed in step S303. Therefore, the second RRC connection reconfiguration message is sent at this time, and a situation in which the eNB side local measurement configuration and the UE side local measurement configuration are inconsistent also causes a failure may occur. Therefore, in this embodiment, the scheme of deleting all measurement configurations is adopted, and then the second measurement configuration is delivered. Therefore, it can be avoided that the measurement configuration on the eNB side is different from the measurement configuration on the UE side, and the UE fails in reconfiguration according to the second measurement configuration.

Please refer to FIG. 6. FIG. 6 is a flowchart showing the operation of the sixth embodiment of the RRC measurement reconfiguration processing method of the present invention.

In step S401, the eNB sends a new measurement configuration (measConfig) to the UE by using an RRC connection reconfiguration (RRCConnectionReconfiguration) message in a scenario in which the UE is moved, the intra-system handover, the inter-system handover, or other functions are caused by the measurement reconfiguration. The RRC connection reconfiguration message reconfigures the eNB side local measurement configuration.

Step S402, the UE receives the RRC connection reconfiguration message, reconfigures the UE side local measurement configuration according to the RRC connection reconfiguration message, and sends an RRC connection reconfiguration complete message (RRCConnectionReconfigurationComplete) message to the eNB after the configuration is successful.

Step S403, the UE does not receive the ACK response of the RRC connection reconfiguration complete message within the preset time, and then the UE side local measurement configuration is rolled back to the measurement configuration before the reconfiguration, and the RRC connection reestablishment request is sent to the eNB (RRCConnectionReestablishmentRequest). Message.

Step S404, the eNB receives the RRC connection reestablishment message before receiving the RRC connection reconfiguration complete message, and then backs up the eNB side local measurement configuration to the measurement configuration before the reconfiguration, and sends an RRC Connection Reestablishment message to the UE. .

Step S405: After receiving the RRC connection reestablishment message, the UE performs a local measurement configuration. The RRC Connection Reestablishment Complete (RRCConnectionReestablishmentComplete) message is then sent to the UE.

Step S406, after receiving the RRC connection reestablishment complete message, the eNB sends an RRC connection reconfiguration message. That is, the measurement configuration that has been in effect is deleted by the RRC connection reconfiguration message, and the initial measurement configuration is delivered to the UE.

Step S407, after receiving the RRC connection reconfiguration message and completing the execution, the UE returns an RRC connection reconfiguration complete message to the eNB.

Step S408, when the eNB receives the RRC Connection Reconfiguration Complete message, the process ends.

Referring to FIG. 7, FIG. 7 is a flowchart showing the operation of the seventh embodiment of the RRC measurement reconfiguration processing method of the present invention.

The processing method steps of the RRC measurement reconfiguration include:

In step S501, in a scenario in which the UE is moved, the intra-system handover, the inter-system handover, or the other function causes the measurement reconfiguration or the integrity protection check fails, the eNB sends a new measurement configuration by using the RRC connection reconfiguration message, and according to the RRC. The connection reconfiguration message reconfigures the eNB side local measurement configuration.

Step S502: The UE detects an uplink out-of-synchronization before receiving the RRC connection reconfiguration message, or performs an integrity protection check failure on the RRC connection reconfiguration message after receiving the RRC connection reconfiguration message, and retains the existing UE side. The configuration is measured locally and an RRC Connection Reestablishment Request message is sent to the eNB.

In step S503, the eNB receives the RRC connection reestablishment request message before receiving the RRC connection reconfiguration complete message, and then the eNB side local measurement configuration is rolled back to the measurement configuration before the reconfiguration, and the RRC connection reestablishment message is sent to the UE.

Step S504: After receiving the RRC connection reestablishment message, the UE performs a local measurement configuration, and then sends an RRC connection reestablishment complete message to the UE.

Step 505: After receiving the RRC connection reestablishment complete message, the eNB sends an RRC connection reconfiguration message. That is, the measurement configuration that has been in effect is deleted by the RRC connection reconfiguration message, and the initial measurement configuration is delivered to the UE.

Step S506, after receiving the RRC connection reconfiguration message and completing the execution, the UE returns an RRC connection reconfiguration complete message to the eNB.

Step S507, when the eNB receives the RRC Connection Reconfiguration Complete message, the flow ends.

Please refer to FIG. 8. FIG. 8 is a flowchart showing the operation of the eighth embodiment of the RRC measurement reconfiguration processing method of the present invention.

In step S601, the eNB sends the first measurement configuration by using the RRC connection reconfiguration message in the scenario that the measurement of the reconfiguration or the integrity protection check fails in the UE, the intra-system handover, the inter-system handover, or other functions, and the eNB sends the first measurement configuration by using the RRC connection reconfiguration message. An RRC connection reconfiguration message reconfigures the eNB side local measurement configuration.

Step S602: The UE receives or completes the first RRC connection reconfiguration failure, reserves the local measurement configuration, or reconfigures the local measurement configuration according to the first RRC connection reconfiguration message, and sends an RRC connection reestablishment request message to the eNB.

In step S603, the eNB receives the RRC connection reestablishment request message before receiving the first RRC connection reconfiguration complete message, and then sends an RRC connection reestablishment message to the UE.

Different from the foregoing sixth and seventh embodiments, in this embodiment, the eNB does not perform the local measurement configuration to fall back to the measurement configuration before the reconfiguration. Instead, the RRC connection reestablishment message is directly delivered.

Step S604: After receiving the RRC connection reestablishment message, the UE performs a local measurement configuration, and then sends an RRC connection reestablishment complete message to the UE.

Step S605, after receiving the RRC connection reestablishment complete message, the eNB sends a second RRC connection reconfiguration message. Deleting all measurement configurations and delivering a second measurement configuration to the UE by using the second RRC connection reconfiguration message.

After the RRC connection reestablishment is successfully performed, the second RRC connection reconfiguration is performed. Since the eNB side local measurement configuration rollback operation is not performed in step S603. Therefore, the second RRC connection reconfiguration message is sent at this time. It may happen that the eNB-side local measurement configuration and the UE-side local measurement configuration are inconsistent and also cause a failure. Therefore, in this embodiment, the scheme of deleting all measurement configurations is adopted, and then the second measurement configuration is delivered. Therefore, it can be avoided that the measurement configuration on the eNB side is different from the measurement configuration on the UE side, and the UE fails in reconfiguration according to the second measurement configuration.

Step S606, after receiving the RRC connection reconfiguration message and completing the execution, the UE returns an RRC connection reconfiguration complete message to the eNB.

Step S607, when the eNB receives the RRC Connection Reconfiguration Complete message, the flow ends.

It can be seen that the RRC measurement reconfiguration processing system in this embodiment can prevent the measurement configuration of the UE and the eNB from being inconsistent and cause the RRC connection reestablishment to fail after the RRC connection reconfiguration failure is encountered.

The invention also provides a user equipment UE.

Referring to FIG. 9, FIG. 9 is a schematic block diagram of an embodiment of a user equipment UE according to the present invention.

The UE includes:

The first configuration module 101 is configured to reconfigure the local measurement configuration according to the radio resource control RRC connection reconfiguration message acquired from the evolved base station eNB, and send an RRC connection reconfiguration complete message to the eNB.

The UE includes a local measurement configuration prior to performing reconfiguration, and a local measurement configuration reconfigured according to the RRC Connection Reconfiguration message. For the sake of distinction, the measurement configuration used before reconfiguration is recorded as the first measurement configuration; the measurement configuration used after reconfiguration is recorded as the second measurement configuration. That is, the above steps may also be expressed as: replacing the local measurement configuration from the first measurement configuration to the second measurement configuration according to the RRC connection reconfiguration message.

The second configuration module 102 is configured to determine that an acknowledgment response of the RRC connection reconfiguration complete message is not received within a preset time after the RRC connection reconfiguration complete message is sent, and the local measurement configuration is rolled back to The previous measurement configuration is reconfigured and an RRC Connection Reestablishment Request message is sent to the eNB.

The UE provided by this embodiment fails to send the RRC connection reconfiguration complete message to the eNB when the radio link fails, and the ACK response of the RRC connection reconfiguration complete message is not received. Then the RRC connection reestablishment between the UE and the eNB will be caused. Since the solution falls back to the reconfiguration before the reconfiguration of the measurement configuration in the UE, and the pre-reconfiguration measurement configuration is the previously successfully performed measurement configuration, it can be ensured that the corresponding measurement configuration also exists in the eNB. Therefore, the UE and the eNB are prevented from failing to reestablish the RRC connection due to different measurement configurations during the RRC connection reestablishment.

Preferably, the UE further includes:

The verification module 103 is configured to perform an integrity protection check on the RRC connection reconfiguration message; if the verification fails, send an RRC connection reestablishment request message to the eNB; if the verification is successful, reconfigure according to the RRC connection The message is reconfigured with a local measurement configuration.

Preferably, the UE further includes:

The link detection module 104 is configured to detect the radio link, and if an abnormality occurs in the radio link, send an RRC connection reestablishment request message to the eNB; if an abnormality occurs in the radio link, for example, uplink out-of-synchronization, Receiving an RRC Connection Reconfiguration message from the eNB.

Referring to FIG. 10, FIG. 10 is a schematic diagram of a module of a first embodiment of an evolved base station eNB according to the present invention.

The evolved base station eNB includes:

The second reconfiguration module 201 is configured to send an RRC connection reconfiguration message to the UE, and reconfigure the local measurement configuration according to the RRC connection reconfiguration message.

The second reconstruction module 202 is configured to determine that before receiving the RRC connection reconfiguration complete message from the UE, receiving the RRC connection reestablishment request message from the UE, the local measurement configuration is rolled back to the measurement before the reconfiguration Configure and send an RRC connection reestablishment message to the UE.

The eNB provided by the embodiment, in the scenario of the radio link failure and the integrity check failure, causes the RRC connection reestablishment between the UE and the eNB after the RRC connection reconfiguration failure occurs, because the scheme locally localizes the eNB. The measurement configuration is rolled back to the measurement configuration before reconfiguration, and the measurement is configured as a configuration that was successfully reconfigured before, so that the corresponding measurement configuration is also present in the UE. Therefore, the UE and the eNB are prevented from failing to reestablish the RRC connection due to different measurement configurations during the RRC connection reestablishment.

Referring to FIG. 11, FIG. 11 is a schematic diagram of a module of a second embodiment of an evolved base station eNB according to the present invention.

That is, the eNB includes a local measurement configuration before performing reconfiguration, and a local measurement configuration reconfigured according to the RRC connection reconfiguration message.

The second re-establishment module 302 is configured to determine that the RRC connection reestablishment request message from the UE is received before the RRC connection reconfiguration complete message is received from the UE, and then the RRC connection reestablishment message is sent to the UE.

When the radio link fails or the integrity check fails, the UE does not issue an RRC connection reconfiguration complete message, or the UE issues an RRC connection reconfiguration complete message, but the eNB does not receive the situation. Then, at this time, the eNB will receive an RRC connection reestablishment message from the UE. Different from the previous embodiment, in this embodiment, the local measurement configuration is not rolled back to the measurement configuration before the reconfiguration when the RRC connection reestablishment message is sent.

The initial reconfiguration module 303 is configured to send a second measurement configuration to the UE and send a second measurement configuration by using the second RRC connection reconfiguration message after receiving the RRC connection reestablishment complete message from the UE.

After the RRC connection reestablishment is successfully performed, the second RRC connection reconfiguration is performed. The eNB side local measurement configuration rollback operation is not performed when the RRC connection reestablishment is performed. Therefore, the second RRC connection reconfiguration message is sent at this time, and a situation in which the eNB side local measurement configuration and the UE side local measurement configuration are inconsistent also causes a failure may occur. Therefore, in this embodiment, the scheme of deleting all measurement configurations is adopted, and then the second measurement configuration is delivered. Therefore, it can be avoided that the measurement configuration on the eNB side is different from the measurement configuration on the UE side, and the UE fails in reconfiguration according to the second measurement configuration.

The present invention also provides a processing system for RRC measurement reconfiguration.
