Technical Field

Background

A dual-connection or multi-connection technology is a technology introduced in Long Term Evolution (LTE), and refers to that two or more base stations simultaneously provide service for one User Equipment (UE). In a dual-connection or multi-connection state, the UE may be connected to two or more base stations simultaneously, and the two base stations provide data transceiving services for the UE simultaneously, so that the service data transmission rate of the UE is increased by multiple times.

With the network deployment and operation of LTE, LTE mobile networks have become larger and more complex, and if a conventional configuration manner is used to configure neighboring cells, it will certainly consume high labor cost and is prone to error. In order to reduce the cost and ensure the stability of the system, an Automatic Neighbor Relation (ANR) mechanism has been introduced into LTE to implement Automatic optimization of the ANR.

However, in the prior art, the dual connectivity/multiple connectivity technology and the ANR work independently, so that a new solution for cooperation of the dual connectivity/multiple connectivity technology and the ANR is needed.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a User terminal (UE) 11 and a network-side Device 12, where the User terminal 11 may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that a specific type of the User terminal 11 is not limited in the embodiment of the present invention. The network side device 12 may be a macro station, an LTE eNB, a 5G NR NB, or the like; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, or the network side device 12 may be an Access Point (AP); the base station may also be a network node formed by a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) managed and controlled by the CU. It should be noted that the specific type of the network-side device 12 is not limited in the embodiment of the present invention.

The UE 11 is connected to a plurality of network-side devices 12 simultaneously (only 2 are shown in the figure), so as to implement dual connectivity or multi-connectivity.

When the UE is configured by the network side device to perform the ANR procedure, the UE may self-plan a data transceiving interval (autonomous gap). During the data transceiving interval, the UE is allowed to autonomously adjust the receiver to collect system information of the network-designated cell. When the UE receives system information of a cell designated by the network, data transmission and reception between the UE and the first network-side device and between the UE and at least one second network-side device may be interrupted.

As shown in fig. 2, the UE accessing to the eNB a completes the measurement of the conventional neighboring Cell and reports the measurement result, and the measurement report uses the combination of the frequency point of the Cell B and the Physical Cell Identifier (PCI) as the measured Cell Identifier. The eNB a finds that the frequency point and the PCI carried in the measurement report correspond to an unconfigured neighbor Cell, and then instructs the UE to read broadcast information of a Cell corresponding to the combination of the frequency point and the PCI to obtain parameters such as a Global identity (CGI), a Tracking Area Code (TAC), and a Public Land Mobile Network identity (PLMN) of the Cell B. The indication is issued to the UE in the form of measurement configuration and is associated with a measurement ID.

After the measurement configuration is obtained, the UE starts a timer and starts to obtain system information of the target cell. If the UE obtains the required information before the timer is overtime, reporting the information of the measurement ID, the PCI, the TAC, the CGI, the PLMN and the like to the network; if the timer is overtime and the UE has not obtained all the needed information, the UE reports the measurement ID to the network. Because the reported information does not include the required information, the eNB a can estimate that the UE has not successfully acquired the required neighbor cell information. If the UE successfully acquires and feeds back the required information, the eNB a may add the cell B to the neighboring cell relationship table of the cell a.

During the timer run, the UE may self-plan the data transceiving interval during which the UE is allowed to autonomously adjust the receiver to collect system information for the designated cell of the network. When the UE is in the dual connectivity state, data transceiving between the UE and the connected eNB may be interrupted.

Referring to fig. 3, fig. 3 is a flowchart of a notification method provided in an embodiment of the present invention, applied to a communication device, where the communication device is a first communication device, and as shown in fig. 3, the method includes the following steps:

step 301, when the UE is configured by a first network-side device to execute an Automatic Neighbor Relation (ANR) procedure, sending a first notification message to a second network-side device, indicating that the UE is configured to execute the ANR procedure.

In the embodiment of the invention, in a communication system adopting a dual-connection or multi-connection technology, the UE is simultaneously connected with the first network side equipment and the at least one second network side equipment, and the first network side equipment and the at least one second network side equipment can simultaneously provide data transceiving service for the UE. When the UE is configured by the first network-side device to perform the ANR procedure, the communication device may send a first notification message to the second network-side device to indicate to the second network-side device that the UE is configured to perform the ANR procedure.

The communication device may be the UE or a first network side device, that is: the UE may send the first notification message to a second network side device; alternatively, the first network side device may send the first notification message to the second network side device.

In the prior art, since the ANR procedure and the dual-connection/multi-connection are independent of each other, when the UE is configured to perform the ANR procedure, the second network-side device does not know that the UE is configured to perform the ANR operation. When data receiving and sending interruption caused by the execution of the ANR flow by the UE occurs, the second network side device considers that an exception occurs (for example, the link quality between the UE and the base station is poor, and the like), and triggers an exception handling flow according to a normal flow (for example, the connection between the base station B and the UE is released, and the like); or, even if the second network-side device does not trigger the abnormal operation, during the data transceiving interval, since the UE does not receive the data packet sent by the second network-side device or does not have an Acknowledgement (ACK), the second network-side device retransmits the sent data packet to the UE, which results in unnecessary resource waste.

The "exception" is actually a normal phenomenon occurring in the process of performing the ANR operation by the UE, and the exception handling process should not be triggered, otherwise, the problems of resource waste, long-time communication interruption, and the like may be caused.

In this embodiment of the present invention, in a communication system that employs a dual connectivity or multi connectivity technology, when a UE is configured by a first network-side device to execute an ANR procedure, a first notification message is sent to a second network-side device by a communication device, and the second network-side device learns that the UE is configured to execute the ANR procedure when receiving the first notification message, so that the second network-side device may analyze an abnormality more accurately and perform more targeted processing based on a state of the UE (a state of executing the ANR procedure or a general state), thereby reducing problems caused by the ANR procedure and mutual independence of dual connectivity/multi connectivity.

In this embodiment of the present invention, the ANR flows are initiated by individual UEs independently, so that to facilitate a second network-side device to determine a state of each UE, when the communication device is the first network-side device, the first notification message may carry an identification parameter of the UE, and when the first notification message is sent by the UE, the identification parameter of the UE does not need to be carried.

In this embodiment of the present invention, after the second network-side device receives the first notification message, it may be determined that the UE is configured by the first network-side device to execute the ANR procedure, and record that the state of the UE is: a state in which an ANR procedure is performed (which is different from a state in which the UE does not perform the ANR procedure, and is referred to as a normal state in the embodiments of the present invention). When the state of the UE is the state of performing the ANR procedure, different processing means should be adopted for the "exception" occurring at this stage, so as to reduce the problem caused by the ANR procedure and the dual/multi-connection being independent of each other.

In this embodiment of the present invention, it is necessary to send a notification message to the second network-side device to notify the second network-side device, and the UE is configured to execute an ANR procedure.

The first notification message may include a field to indicate that a type of the first notification message is a notification message to indicate that the UE is configured to perform an ANR flow. Of course, the notification message may also be implemented using some reserved fields in an existing notification message, i.e., setting some reserved fields in an existing notification message to indicate that the UE is configured to perform the ANR procedure.

In a specific embodiment of the present invention, after the UE is configured to perform ANR, the state change of the UE includes two changes:

at time T1, when the ANR flow starts to be executed (at time T1), the state changes from the normal state to the state in which the ANR flow is executed;

at time T2, when the ANR flow is completely executed, the state of the ANR flow is changed from the state of execution to the normal state.

It has been mentioned before that when the UE is configured to perform the ANR procedure, the terminal UE may self-plan a data transceiving interval (autonomous gap), that is, when the UE actually performs the ANR procedure, the network side is uncertain. That is, the time point T1 is uncertain to the network side.

In the embodiment of the present invention, different processing means need to be taken for "exception" according to the state of the UE, so the determination of the time point T1 and the time point T2 is important.

In the embodiment of the present invention, the second network-side device may determine the time points T1 and T2 in various ways, which are described below respectively.

Implementation mode one

In the first implementation manner, the second network side device may determine the time point T1 and the time point T2 by receiving the time point of the first notification message and preset time information, for example:

t1 is a time point when the second network side device receives the first notification message, and T2 is T1+ preset duration;

or

T1 is a time Δ T1 after the time point when the second network side device receives the first notification message, and T2 is T1+ Δ T1+ preset duration.

Implementation mode two

In the second implementation manner, the second network-side device may determine the time point T1 and the time point T2 according to the time point of receiving the first notification message and the timing duration T of the timer started by the UE executing the ANR procedure, for example:

t1 is a time point when the second network side device receives the first notification message, and T2 is T1+ T;

or

T1 is a time Δ T2 after the time point when the second network side device receives the first notification message, and T2 is T1+ Δ T2+ T;

or

T1 is a time point when the second network-side device receives the first notification message, and T2 is T1+ T + Δ T3.

The Δ T1, Δ T2, Δ T3 and the like can be obtained from statistical historical data or can be obtained based on a mathematical model, and will not be further described here.

The length parameter (i.e., T) of the timer may be directly carried in the first notification message, and the second network side device may directly obtain T by analyzing the first notification message.

The T may also be obtained indirectly by the second network side device through the first notification message, and at this time, the first notification message may carry other parameters having a mapping relationship with T.

In an embodiment of the present invention, the other parameter having a mapping relation with T may be a system parameter of the target Cell, such as at least one of a Physical-layer Cell Identity (PCI), a frequency point and a Radio Access Technology (RAT) type, which is not limited herein.

That is to say, in the specific embodiment of the present invention, when the communication device is the first network side device, the first notification message may carry at least one of the following parameters: an identity parameter of the UE; system parameters of the target cell; a length parameter of the timer (i.e. a timing duration T of the timer started by the UE to perform the ANR procedure); when the first notification message only carries the identification parameter of the UE (corresponding to implementation mode one), the second network side device determines T2 according to a preset duration agreed by a protocol or preset; when the first notification message further carries the system parameter of the target cell and/or the length parameter of the timer (corresponding to implementation mode two), the second network-side device may determine T2 according to the system parameter of the target cell and/or the length parameter of the timer.

When the communication device is the UE, the first notification message may not carry any parameter, and the second network side device determines T2 according to a preset duration agreed by a protocol or preset, or may carry at least one of the following parameters: system parameters of the target cell; the length parameter of the timer, and the second network-side device may determine T2 according to the system parameter of the target cell and/or the length parameter of the timer.

In the foregoing manner, the second network-side device may learn a UE configured to perform an ANR procedure; when the first notification message carries the system parameter of the target cell and/or the length parameter of the timer, the second network-side device may learn, through the system parameter of the target cell and/or the length parameter of the timer, the timing duration T of the timer started by the UE to execute the ANR procedure, so that the second network-side device may more accurately determine the time point T2.

In both the first implementation manner and the second implementation manner, T2 is predicted data, and is not a real time when the UE ends the ANR flow, so in order to accurately grasp a state of the UE, in an embodiment of the present invention, after sending the first notification message to the second network-side device, the method further includes:

and after the ANR flow is ended, sending a second notification message to the second network side device to indicate that the ANR flow is ended.

In this way, after the ANR flow executed by the UE is ended, the communication device may send a second notification message to the second network-side device, so that the second network-side device may know that the ANR flow executed by the UE is ended, and after receiving the second notification message, may determine that the current state of the UE has entered a normal state, and at this time, if an exception occurs again, a normal exception handling flow should be triggered.

The second notification message may include a field to indicate that the type of the second notification message is a notification message to indicate that the ANR flow has ended. Of course, the second notification message may also be implemented by using some reserved fields in an existing notification message, that is, setting some reserved fields in the existing notification message to indicate that the ANR flow has ended.

In the first and second implementation manners, the first notification message may be sent by the terminal or the first network-side device, and the second notification message may also be sent by the terminal or the first network-side device, that is, the messages are sent in four combinations as follows:

the first notification message is sent by the first network side device when the UE is configured to execute the automatic neighbor relation, and the second notification message is sent by the first network side device when the UE is determined to finish the automatic neighbor relation execution process (such as receiving corresponding system information; and such as after receiving a measurement report sent by the UE);

the first notification message is sent by the first network side device when the UE is configured to execute the automatic neighbor relation, and the second notification message is sent by the UE when the UE determines that the process of executing the automatic neighbor relation is finished (such as acquiring corresponding system information from broadcast information; and such as after the UE sends a measurement report);

the first notification message is sent by the UE when determining that the UE is configured to perform the automatic neighbor relation (e.g., after receiving a corresponding measurement configuration), and the second notification message is sent by the first network-side device when determining that the UE performs the end of the automatic neighbor relation procedure (e.g., after receiving a measurement report of corresponding ANR sent by the UE);

the first notification message is sent by the UE when determining that it is configured to perform the ANR (e.g., when receiving the corresponding measurement configuration), and the second notification message is sent by the UE when determining that it is finished performing the ANR (e.g., when acquiring system information required for performing ANR from broadcast information of a specific cell; e.g., after the UE sends a measurement report).

Implementation mode three

In both the first and second implementation manners, T2 is estimated, and then T2 can be corrected by combining the second notification message, so that the accuracy of the UE status information is improved.

In the third implementation, T1 and T2 may be determined directly from the first notification message and the second notification message.

In the third implementation manner, the first notification message does not need to carry any parameter for the second network side device to acquire T, and only needs to determine T1 and T2 according to the reception of the first notification message and the second notification message.

Namely, in the third implementation mode, the method comprises the following steps:

when a communication device is configured by a first network-side device to execute an Automatic Neighbor Relation (ANR) flow, sending a first notification message to a second network-side device, indicating that the UE is configured to execute the ANR flow;

The sender of the first notification message and the sender of the second notification message may be the same or different, that is, the messages are sent in the following four combinations:

the first notification message is sent by the first network-side device when the UE is configured to execute the automatic neighbor relation, and the second notification message is sent by the first network-side device when it is determined that the UE ends the automatic neighbor relation execution process (for example, after a measurement report of corresponding ANR sent by the UE is received);

the first notification message is sent by the first network side device when the UE is configured to execute the automatic neighbor relation, and the second notification message is sent by the UE when the UE determines that the flow for executing the automatic neighbor relation is finished (for example, system information required for executing ANR is obtained from broadcast information of a specified cell; and for example, after the UE sends a measurement report);

In the above embodiment, T1 is the time point when the second network-side device receives the first notification message, or T1 is the time point when the second network-side device receives the first notification message, and T2 is the time point when the second network-side device receives the second notification message.

In combination with the above description, the sending of the second notification message to the second network-side device may include, but is not limited to, the following manners, where:

as shown in fig. 4a, after the first network-side device sends the first notification message to the second network-side device, after the ANR flow ends, the first network-side device sends the second notification message to the second network-side device; or

As shown in fig. 4b, after the UE transmits the first notification message to the second network-side device, the UE may transmit the second notification message to the second network-side device after the ANR flow is ended.

In addition, when the second network-side device receives the second notification message, it may be determined that the ANR flow configured and executed by the UE is ended, and the second notification message may carry information indicating that the ANR flow of the UE connected to the second network-side device is ended.

For example: when the communication device is the first network-side device, the second notification message may carry the identifier parameter of the UE, and the second network-side device may determine, through the identifier parameter of the UE carried in the second notification message, the UE that has finished the ANR procedure.

If the communication device sending the second notification message to the second network-side device is the UE, the second network-side device may directly know that the UE has finished the ANR procedure.

In this embodiment of the present invention, after sending the first notification message to the second network side device, the method may further include:

receiving a first notification response message returned by the second network side equipment after receiving the first notification message; or

And when the first notification response message is not received within a first preset time, retransmitting the first notification message.

In this embodiment, after the communication device sends the first notification message to the second network side device in step 301, the second network side device may send a first notification response message responding to the first notification message to the communication device, and then the communication device may receive the first notification response message returned by the second network side device after receiving the first notification message, so that cooperation between the communication device and the second network side device may be further improved.

And when the first notification response message is not received within the first preset time, the communication device may resend the first notification message, so that the second network side device can accurately record the state of the terminal. As shown in fig. 5a, after the first network-side device sends the first notification message to the second network-side device, if the first notification response message sent by the second network-side device in response to the first notification message is not received within the first predetermined time t1, the first network-side device determines that the second network-side device does not receive the first notification message, and resends the first notification message to the second network-side device, so as to ensure that the second network-side device can receive the first notification message, so as to know that the UE is configured to perform the ANR procedure.

Similarly, after sending the second notification message to the second network-side device, the method further includes:

receiving a second notification response message returned by the second network side equipment after receiving the second notification message; or

And when the second notification response message is not received within a second preset time, retransmitting the second notification message.

In this embodiment, after the communication device sends the second notification message to the second network side device, the second network side device may send a second notification response message responding to the second notification message to the communication device, and then the communication device may receive the second notification response message returned by the second network side device after receiving the second notification message, so as to further improve the cooperation between the communication device and the second network side device.

And when the second notification response message is not received within a second predetermined time, the communication device may resend the second notification message, for example: as shown in fig. 5b, after the UE sends the second notification message to the second network-side device, if a second notification response message sent by the second network-side device in response to the second notification message is not received within a second predetermined time t2, the UE determines that the second network-side device does not receive the second notification message, and resends the second notification message to the second network-side device, so that the second network-side device can receive the second notification message to know that the ANR procedure configured to be executed by the UE has ended.

In the embodiment of the present invention, when the UE is configured by the first network-side device to execute the ANR procedure, the first notification message is sent to the second network-side device to indicate that the UE is configured to execute the ANR procedure, so that in a communication system using a dual-connectivity or multi-connectivity technology, the second network-side device can timely indicate that the UE is configured to execute the ANR procedure to the second network-side device, and the second network-side device can analyze the abnormality more accurately based on the state of the UE and perform more targeted processing, thereby reducing problems caused by the ANR procedure and the mutual independence of the dual-connectivity/multi-connectivity.

Referring to fig. 6, fig. 6 is a flowchart of a notification method provided in an embodiment of the present invention, which is applied to a communication device, where the communication device is a second communication device, and as shown in fig. 6, the method includes the following steps:

step 601, after the ANR flow corresponding to the UE is ended, sending a second notification message to the second network-side device, to indicate that the ANR flow corresponding to the UE is ended.

In the embodiment of the present invention, in a communication system that employs a dual connectivity or multi connectivity technology, that is, a UE is connected to a first network-side device and at least one second network-side device at the same time, and the first network-side device and the at least one second network-side device may provide data transceiving services for the UE at the same time, that is, when the second network-side device receives a first notification message, that is, when the second network-side device knows that the UE is configured to perform an ANR procedure, after the ANR procedure that the UE is configured to perform, that is, an ANR procedure corresponding to the UE ends, the UE or the first network-side device may send a second notification message to the second network-side device to indicate that the ANR procedure corresponding to the UE ends, and the second network-side device may accurately know a time point T2 at which the UE performs the corresponding ANR procedure, so that the second network-side device may timely restore communication between the second network-side device and the UE to a normal state, particularly, misjudgment of the second network side equipment on communication abnormity between the second network side equipment and the UE is reduced.
