Description

Method, device and device for transmitting link abnormal information

Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a method, an apparatus, and a device for transmitting link abnormal information.

Background technique

In the wireless communication system, the interconnection interface between the radio network controller (English: Radio Network Controller, RNC for short) is an interface used by the RNC for signaling and data interaction with other RNCs, and is interconnected between the wireless network subsystems. link.

When a user equipment (English: User equipment, UE for short) establishes a connection to the radio access network and generates a handover on the interconnection interface between the RNCs, more than one RNC resource is used, and different RNCs are used. They serve different roles, for example, Serving Radio Network Controller (SRNC) and Drift Radio Network Controller (DRNC), where SRNC is to maintain UE and The RNC of the interface of the core network is responsible for the data transmission between the core network and the UE and the transfer and reception of the interface signaling with the core network; the DRNC is a RNC other than the SRNC, generally controls the cell used by the terminal, and a terminal There can be more than one DRNC. Figure 1 is a system architecture diagram of the UE switching between the SRNC and the DRNC. During the interface switching between the RNCs, the SRNC sends a radio link setup request message to the DRNC. After receiving the DRNC, the DRNC performs a radio link on the DRNC. set up. After the DRNC radio link is successfully established, the SRNC returns a radio link setup response message. If the UE moves back to the SRNC cell from the signal coverage edge of the DRNC neighboring cell, the UE will not perform the cross-IUR handover. In this case, the SRNC sends a radio link deletion request message to the DRNC. Radio link deletion at the DRNC. After the DRNC radio link is successfully deleted, the radio link deletion response message is returned to the SRNC. In addition, when the UE is in the process of handover, the radio resource control (English: Radio Resource Control, RRC for short) is released, and the radio link deletion message is also sent to the DRNC. After receiving the DRNC, the DRNC performs radio link deletion in the DRNC. Answer.

According to the above, when the UE is in the scenario of switching between interfaces across the RNC, a lot of processes can be triggered. For example, in the process of soft handover, hard handover, cell update, and RRC release, the SRNC sends a radio link deletion request message to the DRNC to delete the radio link. The DRNC cannot know the specific process information. When the UE loses the call due to poor signal or abnormal processing of the DRNC, the DRNC receives the message still as the radio link deletion request message, and does not know whether the UE is normally released or abnormally released. Causes the user to be unable to analyze and locate the abnormal release.

1 is a schematic diagram of an application scenario of a method for transmitting link abnormality information according to the present invention. The solution of the present invention can be applied to a wireless communication system involving radio network controller signaling and data interaction, as shown in FIG. The application scenario architecture includes: a core network (English: Core Network, referred to as CN), SRNC, DRNC, and a base station that establishes a connection with the SRNC and the DRNC, respectively, and a UE. The SRNC sends a radio link deletion request message to the DRNC during the interface switching between the SRNC and the DRNC; the radio resource control is performed when the user is in the interface switching process between the SRNC and the DRNC (English: Radio Resource Control) , abbreviated as: RRC) release, will also send a radio link deletion request message to the DRNC. During the hard handover of the interface between the SRNC and the DRNC, a new radio link will be created in the new cell to send a face link establishment request message to the DRNC. The radio link deletion request message is also sent to the DRNC to delete the radio link of the cell where the UE is originally located. The existing deletion message is used as the deletion indication. For the DRNC, the specific process information cannot be known. The DRNC receives a message that is still a radio link deletion request message, and does not know whether the UE is normally released or abnormally released. In view of this problem, the present invention proposes a link abnormality. Information transmission scheme.

2 is a flowchart of Embodiment 1 of a method for transmitting link abnormality information according to the present invention; The method is applied to the first controller side, and the first controller may be an RNC of an SRNC or a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system. The implementation steps are:

S101: The first controller sends a radio link deletion request message to the second controller. The radio link deletion request message includes link abnormality information and current signal parameters.

In this step, the link abnormality information is used to indicate the reason for triggering the deletion of the wireless link; two of the RADIO LINK DELETE REQUEST messages sent by the first controller to the second controller are added. The selected cell, when the SRNC normally releases the UE, may not carry the two cells in the radio link deletion request message; when the SRNC abnormally releases the UE, two new ones are added in the radio link deletion request message. The reason for the abnormal release is described in one of the cells, for example, signaling radio bearer (English: signalling radio bearer, SRB) RESET, service radio bearer (English: Traffic Radio Bearer, TRB for short) RESET, RL Failure The radio interface between the UTRAN and the UE (English: The Radio interface between UTRAN and the User Equipment, UU) Wait Timeout, etc. (in which the Universal Terrestrial Radio Access Network (English: Universal Terrestrial Radio Access Network) : UTRAN); carries the current signal quality information in another cell, ie the current signal parameter, eg signal to noise ratio (English: Ratio) Of energy per modulating bit to the noise spectral density (abbreviation: EcNo), received signal code power (English: Received Signal Code Power, referred to as: RSCP).

Optionally, before the step, the first controller detects that the link abnormality information is acquired, first sends a radio link release message to the UE, so that the UE releases the radio link, and the first controller receives the The radio link release completion message returned by the UE, when the link is released, the first controller generates the radio link deletion request message according to the link abnormality information.

S102: The first controller receives a radio link deletion response message returned by the second controller.

Transmitting a radio link deletion request message carrying the link abnormality information and the current signal parameter to the second controller, so that the second controller records the information, and deleting the radio link indicating that the message is to be deleted, And returning a RADIO LINK DELETE RESPONSE message to the first controller after the deletion is completed, so that the first controller confirms that the corresponding wireless link has been deleted.

The link abnormality information and the signal parameter saved by the second controller may be recorded and stored in the form of the voice system and the log information, so that the maintenance personnel can quickly locate whether the UE is abnormally released during the maintenance process, and can quickly determine the abnormality. Reason for release.

In the method for transmitting the link abnormality information provided by the embodiment, the first controller sends the link abnormality information and the signal parameter to the second controller, and the second controller sends the link abnormality information and the signal parameter to the second controller. Statistics and records are used to quickly locate the cause of abnormal link release based on the information during maintenance.

3 is a flowchart of Embodiment 2 of a method for transmitting link abnormality information according to the present invention; as shown in FIG. 3, the method is applied to a second controller side, and the second controller may be a base station of a DRNC or a TD-SCDMA system. The specific implementation steps are:

S201: The second controller receives a radio link deletion request message sent by the first controller. The radio link deletion request message includes link abnormality information and current signal parameters.

In this step, the link abnormality information is used to indicate the reason for triggering the deletion of the wireless link, and a new cell is added in the wireless link deletion request message, and the reason for the abnormal release may be SRB RESET, TRB RESET. At least one of RL Failure, UU Wait Timeout, and the like; another cell added in the radio link deletion request message carries current signal quality information, that is, current signal parameters, for example, EcNo, RSCP.

S202: The second controller records, in the voice system and the log information, the link abnormality information and the current signal parameter carried in the wireless link deletion request information, and deletes the wireless link.

In this step, the second controller may delete the radio link indicated by the radio link deletion request information, and then record the telecommunication system and log information according to the link abnormality information carried in the link and the current signal parameter. Record the voice and log information first and then delete the wireless link.

In any embodiment of the present invention, after receiving the RL DELETE REQUEST message carrying the added cell, the DRNC records the message and the log information. The system includes at least one of the following: each reason for triggering the deletion of the wireless link, the corresponding number of times, the statistical information of the service type, the statistical information of the transmission channel of the signaling plane or the user plane, and the segmentation statistics of the signal quality. information. The log information includes at least one of abnormal information, a service type, a transmission channel, a signal quality, and a signal parameter carried by each radio link deletion request message.

In the specific implementation, the system can be based on the following aspects:

1) Statistics of the currently existing service types. If there is circuit switching (English: Circuit Switch, referred to as CS, packet switching (English: Packet Switch, PS for short) service or CS and PS services at the same time for statistics.

2) Statistics on the current signaling plane or the user plane's transmission channel. For example, whether the transmission channel of the signaling plane is carried on an enhanced dedicated channel (English: Enhanced Dedicated Channel, DCH for short), High Speed Downlink Packet Access (HSDPA), and high-speed uplink packet access ( English: High Speed uplink Packet Access (HSUPA) for statistics; whether the user plane's transport channel is carried on DCH, HSDPA, HSUPA for statistics

3), signal quality EcNo, RSCP segmentation for statistics. For example, the range of values of the protocol of EcNo and RSCP is divided into three sections: good, medium, and bad. When the statistics user is released abnormally, the value of EcNo and RSCP falls within the range, and the corresponding system is counted. If the quality of the user signal is good, but the number of abnormal release is relatively high, it indicates that the processing of the RNC may be abnormal, resulting in abnormal release of the user.

In any of the scenarios, the service information, the signaling plane, or the user plane's transmission channel, signal quality, and some detailed information can be recorded in the log information, so that the maintenance personnel can analyze and locate the abnormal release reason of the single user.

S203: The second controller returns a radio link deletion response message to the first controller.

After completing the recording of the voice system and the log information, and completing the deletion of the wireless link indicated by the first controller, the second controller sends a wireless link deletion response message to the first controller to notify the first controller to complete the deletion. .

The method for transmitting the link abnormality information provided by the embodiment, by receiving the wireless link deletion request message that carries the link abnormality information and the current signal parameter sent by the first controller, records the voice system and the log information, and is used for maintenance. You can quickly locate the cause of abnormal link release based on this information.

4 is an interaction diagram of an example of a method for transmitting link abnormality information according to the present invention; as shown in FIG. 4, based on the foregoing two embodiments, the SRNC and the DRNC are taken as an example to provide link abnormality information provided by the present invention. The detailed application process of the transmission method is specifically described. The specific steps include:

S301: The SRNC detects the abnormal information and triggers an RRC abnormal release process.

In this step, the SRNC checks the abnormal information such as SRB RESET, TRB RESET, RL Failure, and UU Wait Timeout, triggers the RRC abnormal release procedure, and generates a corresponding RRC connection release message.

In any embodiment, the SRB RESET is that after the SRNC sends the signaling plane message to the UE, the SRNC does not receive the acknowledgment message returned by the UE for the message, resulting in abnormal release.

TRB RESET means that after the SRNC sends the user plane data to the UE, the SRNC does not receive an acknowledgment message that the UE returns an acknowledgement message for the user plane data, resulting in an abnormal release.

RL Failure refers to the abnormal release of the RL synchronization failure between the NodeB and the UE.

The UU Wait Timeout means that the SRNC does not receive the response message sent by the UE to the UE after sending the signaling plane message to the UE, resulting in abnormal release. For example, if the SRNC sends an ACTIVE SET UPDATE message to the UE, the UE returns a response message of the ACTIVE SET UPDATE COMPLETE. If the SRNC does not receive the response message of the ACTIVE SET UPDATE COMPLETE sent by the UE, the RRC link is abnormally released. The reason for the release is the UU Wait Timeout.

There are two main reasons for sending the above situations: 1) The air interface signal is not good, and communication between the UE and the RNC is impossible. Or 2), the internal processing of the RNC is abnormal, and the signaling plane message and the user plane data are not sent to the UE, or the RL synchronization is abnormal, which may be caused by the abnormal processing of the DRNC.

S302: The SRNC sends an RRC connection release message to the UE.

In this step, the SRNC sends an RRC CONNECTION RELEASE message to the UE, informing the UE to release the RRC Link message.

S303: The UE returns an RRC connection release complete message to the SRNC.

In this step, after receiving the RRC CONNECTION RELEASE message, the UE returns the RRC CONNECTION RELEASE COMPLETE message to the SRNC after completing the RRC connection release, but the RNC may be internal due to poor signal. The SRNC cannot receive the RRC CONNECTION RELEASE COMPLETE message for reasons such as handling exceptions.

S304: The SRNC sends a radio link deletion request message to the DRNC.

In this step, the SRNC sends a RL DELETE REQUEST message to the DRNC, carrying a new optional cell in the message, and describing the cause of the common abnormal release in the first cell, if SRB RESET TRB RESET, RL Failure, UU Wait Timeout, etc.; carry the current signal parameter information, such as EcNo, RSCP, in the second cell.

S305: The DRNC records the voice system and the log information according to the radio link deletion request message, and deletes Wireless link.

In this step, the DRNC deletes the radio link indicated by the radio link deletion request message, and records the telecommunication system and the log information. The same as the previous embodiment, the data may be calculated according to the following aspects: the currently existing service The type is used for statistics, the current signaling plane or the user plane's transmission channel for statistics, and the signal quality EcNo, RSCP segmentation for statistics. That is, different channels can be recorded according to different reason values. For example, if the reason for not receiving the acknowledgment message from the UE is 5 times, then the number of times the statistic value is defined is 5; the other reason values also have a statistic, and the number of statistics is respectively counted. Signal parameters can also be statistically calculated. For example, different ranges of signals can be defined as excellent, good, medium, and poor, and four channels are defined. Each time the signal falls within this range, the corresponding channel is counted. The log information is used to record the abnormal information and signal parameters carried in each link deletion for subsequent problem analysis.

S306: The DRNC returns a radio link deletion response message to the SRNC.

In this step, after the DRNC completes the radio link deletion, when the DRNC radio link is deleted successfully, the SRNC returns a RADIO LINK DELETE RESPONSE message to inform the DRNC to complete the radio link deletion.

In the foregoing process, the link abnormality information and the signal parameter are carried in the radio link deletion request message by the combination of the hardware and the software of the device, and the device at the receiving end identifies the information through software analysis, and records the information.

The subsequent analysis or processing can be performed by using the data or the log records, which may be performed by the device itself, or may be performed by the maintenance personnel to analyze the information. This solution is not limited.

In the transmission scheme of the link abnormality information provided by the embodiment, the DRNC records abnormally releasing the user's voice system and the log record, and the reason why the abnormal release is quickly located in the maintenance process is caused by the abnormal processing of the DRNC, and the cause of the abnormal call drop is determined. Improve processing efficiency.
