Which data transmission link or failure has failed.

 The specific manner in which the base station receives the NACK or the DTX may be continuous receiving a preset number of NACKs or DTXs, or may be discretely receiving a preset number of NACKs or DTXs within a preset period of time.

 In addition, the embodiment of the present invention further provides a method for detecting a link in a multi-service cell configuration, involving a radio network controller, as shown in FIG. 4, including:

 401. Receive a radio link failure indication message sent by the base station, where the radio link failure indication message carries the radio link failure information.

 402. According to the radio link failure information, delete the failed data transmission link for the terminal, or deactivate the failed data transmission link, so as to suspend data transmission on the user plane, or reconfigure the data transmission link for the terminal, so that Data transfer.

Determining the failed data transmission link, then deleting or deactivating the failed data transmission link, or reconfiguring the data transmission link for the terminal to replace the failed data transmission link.

An embodiment of the present invention provides a method for detecting a link in a multi-serving cell configuration, first by The base station receives the uplink feedback result of the terminal. When the uplink feedback result includes the NACK or the DTX, the base station sends a radio link failure indication message to the radio network controller, and carries the radio link failure information in the radio link failure indication message, and then wirelessly The network controller may delete or deactivate the failed data transmission link according to the radio link failure information, or reconfigure the data transmission link. In this way, the radio network controller can determine the data transmission link of the terminal failure as soon as possible according to the radio link failure information sent by the base station, and redistribute the data transmission link to maintain the network service stability of the terminal.

 In addition, the method for detecting a link in another multi-serving cell configuration is also provided in the embodiment of the present invention. As shown in FIG. 22, the method includes:

 2201. The base station sends a power control instruction to the terminal.

 In a practical application, the power control command is carried in a TPC (Transmit Power Control) command word in the F-DPCH (Fractal Networked Physical Channel). However, in some special cases, that is, the system does not have the F-DPCH configured, the TPC command word can also be configured in the DPCCH (Dedicated Physica Physica l Cont ro l Channe l). The difference between DPCCH and F-DPCH is that the former can only communicate with a single terminal at the same time, and the latter can communicate with multiple terminals at the same time.

 The power control command described in step 2201 may instruct the terminal to increase or decrease a certain power value based on the original transmit power. The specific manner may be: when the base station detects that the signal-to-interference ratio of the signal sent by the terminal is less than a preset threshold, the terminal is instructed to add a power value based on the original transmit power, and the base station detects the last time of the terminal. When the signal-to-interference ratio of the transmitted signal is greater than a preset threshold, the terminal is instructed to reduce a power value based on the original transmission power. The power value can be a predetermined unit quantity or a specific power value.

 If the data transmission link between the base station and the terminal is normal, the terminal can normally receive the power control command and change the power of transmitting data to the base station according to the power control command. Otherwise, the terminal will not change the power of the transmitted data according to the power control command.

 The base station receives the uplink control signaling sent by the terminal.

 2203. Determine whether the power of the uplink control signaling meets an indication of changing the transmit power of the power control command.

The indication of changing the transmission power is included in the power control instruction, and is used to indicate that the terminal changes Transmit power. In a practical application, the specific method of the determining in step 2203 is: first, by measuring the pilot in the received uplink dedicated physical control channel (DPCCH, Dedica ted Phys i ca l Cont rol CHanne l ), calculating and transmitting the uplink. Controlling the signal-to-interference ratio (SIR, S igna l-to-interference) of the terminal, and then comparing the detected signal-to-interference ratio of the terminal with the signal-to-interference ratio before the terminal receives the power control command, and determining the uplink Controlling whether the power of the signaling conforms to an indication of a change in transmit power of the power control command.

 For ease of understanding, the determination process described in step 2203 is illustrated as an example:

 If the power control command instructs the terminal to add a certain power value based on the original transmit power, the method of determining is:

 The power control command is instructed to add a certain power value to the terminal based on the original transmit power, for example, 1 in the TPC command word of the F-DPCH. The base station first detects the signal-to-interference ratio of the terminal before receiving the power control command, that is, by measuring the pilot in the uplink dedicated physical control channel received before, and calculating the signal-to-interference ratio of the terminal transmitting the uplink control signaling, setting the power Is m. Then detecting the signal-to-interference ratio of the terminal after receiving the power control command: detecting the signal-to-interference ratio of the terminal within a preset period, assuming that the power detected in the first period is m, the second period is detected. The power is n. The change in the signal-to-interference ratio of the terminal relative to the original signal-to-interference ratio is 0 (m-m = 0) in the first cycle and 0 or decreased (n < m) in the second cycle. Therefore, it can be determined that the detected transmission power of the terminal does not change according to the power control command (that is, increased based on the original transmission power), indicating that the data link is abnormal, and the link needs to be detected in time. In practical applications, the preset period is usually expressed in Slot. It should be noted that in order to obtain the conclusion of the detection link, the change of the transmission power of the terminal relative to the original transmission power must last more than one S lot.

 2204. The base station sends the radio link failure information to the radio network controller.

 When the power of the uplink control signaling does not meet the indication of changing the transmit power of the power control command, indicating that the data transmission link between the base station and the terminal fails, the base station generates a radio link failure information, in the radio link failure information. Carrying identification information of the failed data transmission link.

 2205. According to the radio link failure information, the radio network controller deletes or deactivates the failed data transmission link, or reconfigures the data transmission link for the terminal to perform data transmission.

In step 2204, the base station may only when the power of the uplink control signaling does not meet the power. When the control command changes the indication of the transmission power, the radio link failure information is transmitted to the radio network controller. Alternatively, the radio link failure information may be sent to the radio network controller regardless of whether the power of the uplink control signaling conforms to the indication of changing the transmission power of the power control command, for example, when the power of the uplink control signaling conforms to the change of the power control command. When the power is indicated, the identification information of the failed data transmission link is not carried in the radio link failure information. Further, the trigger condition for transmitting the radio link failure information may be set, for example, the trigger condition is set to: In consecutive X times, there are Y times (X, Y is an integer greater than or equal to 1, and When X is greater than or equal to Y), when the power of the uplink control signaling does not meet the indication of changing the transmit power of the power control command, the radio link failure information is sent to the radio network controller; or consecutive Z times (Z If the power of the uplink control signaling does not meet the indication of the change of the transmit power of the power control command, the radio link failure information is sent to the radio network controller.

 The embodiment provides a method for detecting a link in a multi-serving cell configuration. First, the base station sends a power control command to the terminal, and then receives the uplink control signaling sent by the terminal and determines the power of the uplink control signaling. Whether the indication of changing the transmission power of the power control command is met, and finally the radio link failure information is sent to the radio network controller, so that the radio network controller reconfigures the data transmission link for the terminal. Through the above scheme, the data transmission link of the terminal failure is determined as soon as possible, and the data transmission link is re-allocated to maintain the stability of the network service of the terminal.

 Example 3

 Another embodiment of the present invention provides a method for detecting a link in a multi-service cell configuration, which is related to the terminal side. As shown in FIG. 5, the method includes:

 501. Receive a radio link failure detection reporting condition sent by the radio network controller.

 The radio link failure reporting condition indicates that the terminal reports to the radio network controller when any data transmission link fails, specifically, each serving cell (including the primary serving cell and the secondary serving cell) connected by the terminal using the multi-stream transmission technology In the case where a link between the serving cell and the terminal fails to be connected, the link connection failure information is reported.

502. If the serving cell of the terminal meets the radio link failure detection reporting condition, determine that the terminal has a radio link failure, and generate radio link failure information. 503. Send a radio link failure message to the radio network controller.

 Specifically, the radio link failure information includes identifier information of the data transmission link that satisfies the radio link failure detection reporting condition, so that the radio network controller can know which link fails.

 In addition, the wireless link failure information may further include at least one of the following information:

 The cause of the failure of the wireless link, the location information when the terminal fails the wireless link, the signal strength, and the signal quality. The signal strength can be represented by RSCP (Received S ignal Code Power), the signal quality can be represented by the value of Ec/Io, Ec/Io where E is the energy (energy), and C is the chip (chip). ), Io represents the interference from the serving cell of the non-primary frequency point.

 After the wireless link failure information is sent to the radio network controller, the radio network controller may delete the failed data transmission link for the terminal according to the radio link failure information, or go to the failed data transmission link. Activated to suspend data transmission; or reconfigure the data transmission link for the terminal to continue data transmission.

 On the other hand, the embodiment of the present invention further provides a method for detecting a link in a multi-service cell configuration, which corresponds to the foregoing steps 501 to 502, and relates to a radio network controller. As shown in FIG. 6, the method includes:

 603. According to the radio link failure information, delete the failed data transmission link for the terminal, or deactivate the failed data transmission link, so as to suspend data transmission on the user plane, or reconfigure the data transmission link for the terminal, so that Data transfer.

 Optionally, the radio network controller may send a radio link failure determination indication to the terminal, in addition to sending the radio link failure detection reporting condition. The radio link failure determination indication is used to limit the range of serving cells that need to be detected for the terminal. For example, the radio link failure judgment indication may indicate the terminal, only detecting the primary serving cell of the primary frequency point where the terminal is located, or detecting only the secondary serving cell other than the primary serving cell, or instructing the terminal to establish all the data transmission links. The serving cell performs detection. Therefore, by instructing the command by the radio link failure judgment, the serving cell can be selectively detected, thereby making the detection of the serving cell of the terminal more flexible.

An embodiment of the present invention provides a method for detecting a link in a multi-serving cell configuration, first by The terminal receives the radio link failure detection reporting condition of the radio network controller, and if the serving cell of the terminal satisfies the radio link failure detection reporting condition, the terminal sends the radio link failure information to the radio network controller, and then the radio network controller may according to the radio The link failure information deletes or deactivates the failed data transmission link, or reconfigures the data transmission link. In this way, the radio network controller can determine the data transmission link of the terminal failure as soon as possible according to the radio link failure information sent by the terminal, and redistribute the data transmission link to maintain the network service stability of the terminal.

 Example 4

 An embodiment of the present invention provides a method for detecting a link in a multi-serving cell configuration, as shown in FIG. 7, including:

 701. The wireless network controller sends a system message and/or a wireless network connection signaling to the terminal. The system message and/or the wireless network connection signaling carries a radio link failure detection reporting condition and a radio link failure judgment indication.

 In practical applications, the system message and/or the wireless network connection signaling may only carry the radio link failure detection reporting condition, and according to the radio link failure detection reporting condition, the terminal selects from each serving cell that establishes multi-stream transmission with itself. The serving cell that meets the radio link failure detection reporting condition is reported, and the eligible serving cells are reported to the radio network controller.

 In the embodiment of the present invention, the system message and/or the wireless network connection signaling not only carries the wireless link failure detection reporting condition, but also carries a radio link failure determination indication. The radio link failure determination indication is used to define a range of serving cells that need to be detected for the terminal. For example, the radio link failure judgment indication may indicate the terminal, only detecting the primary serving cell of the primary frequency point where the terminal is located, or detecting only the secondary serving cell other than the primary serving cell, or instructing the terminal to establish all the data transmission links. The serving cell performs detection. Therefore, by instructing the command by the radio link failure judgment, the serving cell can be selectively detected, thereby making the detection of the serving cell of the terminal more flexible.

If the serving cell of the terminal meets the radio link failure determination indication and the radio link failure detection reporting condition, determine that the terminal has a radio link failure, and generate radio link failure information. 703.

 The terminal uses the number of out-of-steps K, the number of synchronizations, and the specific usage of the timer:

 S701 determines whether one of the out-of-synchronization indications is continuously received.

 When the signal quality of the DPCCH or F-DPCH received by the terminal is lower than a preset threshold, the physical layer of the terminal sends an out-of-synchronization indication to the upper layer, when the terminal receives consecutive consecutive out-of-synchronization indications in the serving cell X. , execute S 7012.

 57012, start timer.

 5701 3. Determine whether N synchronization indications are continuously received within the timer time T.

When the signal quality of the DPCCH or F-DPCH received by the terminal is higher than a preset threshold B, the physical layer of the terminal sends a synchronization indication to the upper layer. If the terminal continuously receives N synchronization indications in the serving cell X in the T, it indicates that the data link between the terminal and the serving cell X returns to normal, otherwise the data transmission link between the terminal and the serving cell X is determined to be failed, and the failed data transmission is performed. The identification information of the link is stored in the The line link fails and is sent to the radio network controller.

 The above-mentioned serving cell X refers to any serving cell among all serving cells that establish multi-stream transmission with the terminal. When the terminal only receives the radio link failure detection reporting condition and does not receive the radio link failure determination indication, the terminal may perform the foregoing S7011 to S7013 for all the serving cells, and then send the radio link failure information; immediately receive the radio link. When the failure detection reporting condition receives the radio link failure determination indication, the terminal selects one or more serving cells from all the serving cells according to the radio link failure determination indication (all service cells may also be selected), and executes the foregoing S7011 to S7013. And send a wireless link failure message.

 704. The radio network controller deletes the failed data transmission link for the terminal according to the radio link failure information, or deactivates the failed data transmission link, so as to suspend data transmission on the user plane, or reconfigure the terminal.
