Description

The present invention claims the Chinese patent application filed on March 6, 2009, the Chinese Patent Application No. 200910079288.5, the invention titled "a wireless device service switching method, device and system" Priority is hereby incorporated by reference in its entirety.

The present invention relates to the field of communications technologies, and in particular, to a wireless device, system, and wireless device service switching method.

BACKGROUND OF THE INVENTION In a wireless communication device, a serial cascading bus is widely used, and a serial cascading bus structure is formed between a master device and a slave device through a Serdes, Serialize and Deserialize function. For example, in a distributed base station of Wideband Code Division Multiple Access (WCDMA), the master device corresponds to a radio equipment controller (REC, Radio Equipment Controller), and the slave device corresponds to a radio device (RE, Radio Equipment).

Before the RE and REC establish a normal communication link, the RE must first access the REC. The RE device has two ports, M (Master) port and S (Slave) port, and the RE device is connected to the REC by the S port. REC and RE can form a ring network.

Currently, the RE is provided in the ring to provide the service switching function. As shown in Figure 1, the active and standby RECs send a Service Switch Indication (SSI) message after the start. The basic frame of the radio interface (CPRI) is sent continuously without interruption. If the SSI value is 0, the service forced switching is not performed. If the value is 1, it indicates that the service forced switching needs to be attempted. Figure 1 before switching As shown in the figure, the RE is accessed from the primary REC. After the switchover, as shown in FIG. 2, each RE is accessed from the REC. The direction of the arrow in FIG. 1 and FIG. 2 only indicates the switching of the RE service.

In the scenario where the multi-level RE is connected to the REC in the ring mode, when the existing RE switching scheme occurs, the multi-level REs on the ring can only be reversed to one side, and the RE cannot be allocated between the primary and backup RECs. The service of the level RE is handled by one REC, and the role of the active and standby REC load sharing cannot be achieved. Summary of the invention

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the present invention.

In the following embodiments of the present invention, the wireless device is an RE, and the wireless device controller is an REC as an example. It can be understood that the solution in the embodiment of the present invention is applicable to WCDMA, time division-synchronous code division multiple access (TD-SCDMA). , Time-Division Synchronization Code Division- Multiple-Access), Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), Long Term Evolution (LTE), Global Microwave (LTE) Various network environments such as WIMAX (World Interoperability for Microwave Access).

An embodiment of the present invention provides a method for instructing a service switching of a wireless device. Taking the process shown in FIG. 3 as an example, the method includes the following steps:

Step 30: The REC constructs an SSI message, where the initial value of the SSI is related to the number of REs of the REC expected service;

The value of the SSI can be as follows: 0 - 127 ; For example, the RE is accessed by the Level 3 RE in ring mode. As shown in Figure 1, the current RE0, RE1, and RE2 are connected to the primary REC, if the primary REC. It is expected that RE0 accesses, and the standby REC expects RE1 and RE2 to access, that is, the number of REs that the primary REC expects to serve is one, and the number of REs that the standby REC expects to serve is two, then the primary REC sends SSI: 1 (indicates SSI The SSI value is 1 in the message, and the standby REC sends SSI: 2 (indicating that the SSI value in the SSI message is 2).

Step 31: Send the SSI message, and control the RE service switching according to the value of the SSI.

The primary REC and the standby REC may continuously send respective corresponding SSIs to the CPRI basic frame without interruption. The controlling the RE service switching according to the SSI value may include: If only one SSI value is greater than the specified value, the wireless device may be configured to perform the port switching when the port of the wireless device accessing the wireless device controller is inconsistent with the port receiving the SSI message whose value of the SSI is greater than the specified value.

Further, if the number of SSI messages whose SSI value is greater than a specified value is greater than one, the wireless device does not perform access port switching.

Further, if the value of the SSI in the received SSI message is equal to or less than a specified value, the wireless device does not perform an access port switching, and transmits the SSI message to the next-level device.

In the embodiment of the present invention, when the received SSI value is greater than the specified value, the SSI value is decremented and then transmitted to the next-level device, and the decrement method may be to subtract the SSI value by a specific one. The value of the next-level device may be an RE or an REC. After the REC is transmitted to the REC, the SSI message ends in the REC, and the REC does not perform the switching operation.

Generally, the value of the SSI in the SSI message sent by the active and standby RECs is greater than the specified value. Alternatively, if the value of the SSI is less than the specified value, the value of the SSI may be equal to the specified value. For example, after an SSI value is decremented and sent to a subordinate device, for example, a certain RE, the RE receives the SSI message, and determines that the SSI value in the SSI message is less than or equal to the specified value. , then do not switch, directly pass the SSI message to the next level device.

The specific value and the value of the specified value in the embodiment need to meet the following requirements: After the operation of subtracting the specific value from the SSI value is performed N times, the SSI value is less than or equal to the specified value, where N is a positive integer, and REC expects the number of REs to be the same.

In the embodiment of the present invention, the specific value is 1 and the specified value is 0, and the decrement operation is performed after determining that the SSI value is greater than the specified value, that is, the current RE determines that the SSI value is greater than the specified value 0. , the SSI value is decremented by 1 and then passed to the next level device.

In this embodiment, the RE receives an SSI message from the primary and backup RECs respectively, and the RE may process the SSI message according to the SSI message after receiving another SSI message, and then according to the another SSI message after receiving another SSI message. Process it. RE can also be received after both SSI messages are received. These two SSI messages are processed.

Taking the structure shown in FIG. 1 as an example, if the primary REC sends SSI:1, the standby REC sends SSI:2, and RE0 determines that the SSI value 1 is greater than the specified value 0 after receiving the SSI:1 sent by the primary REC. If the interface S that receives the SSI message is the same as the interface that accesses the REC, the switch does not perform the switchover, that is, the port that the RE accesses the REC does not change, or the RE still accesses the REC through the original port; A value of 0, regardless of the need for switching, subtracts the SSI value by one and passes it to the next level of RE. RE1 receives the SSI of the primary REC: 0. Since the SSI value 0 is equal to the specified value 0, no need to switch, continue to deliver the SSI message of the primary REC to RE2; RE2 receives the SSI of the primary REC: 0, because the SSI value 0 is equal to the specified value of 0, no need to switch.

RE2 receives the SSI from the standby REC: 2, determines that the SSI value 2 is greater than 0, and determines that the interface M that receives the SSI message does not match the interface S of the access REC, performs switching, and decrements the SSI value by one. Continue to pass down; RE1 receives the SSI of the standby REC: 1, determines that the value of SSI is greater than the specified value of 0, and determines that the interface M that receives the SSI message does not match the interface S of the access REC, then performs the switchover, and the switch The SSI value of the SSI message sent by the standby REC is decremented by 1 and then passed down to RE0. Since the SSI value is 0, RE0 does not perform switching on the received SSI message of the standby REC. The connection structure after the above-mentioned switching processing is as shown in FIG. 4, and the arrow direction in FIG. 4 is only used to indicate the switching of the service.

Optionally, if the RE receives two SSI messages from the two ports, and the SSI values in the two SSI messages are greater than the specified value, the RE does not perform the port switching.

For example, still taking FIG. 1 as an example, in the case that the primary REC and the standby REC simultaneously send SSI: 2, the SSI values of the SSI messages sent by the RE1 on the primary REC and the standby REC are greater than the specified value 0, according to the above. In the processing mode, there will be RE1 - access to the primary REC, and then switched over to access the standby REC, so that repeated switching occurs. Therefore, in the above case, that is, the RE is from at least two When two ports receive two SSI messages, and the two SSI values are greater than the specified value, the RE does not perform the access port switching, and the at least two SSI values are decremented by one and then transmitted to the corresponding next level. RE. In this embodiment, when the SSI received by the two ports from RE1 is greater than 0, no switching is performed. deal with.

The method in the foregoing embodiment of the present invention implements the REC to share the RE service according to its own capabilities, and implements load sharing of the active and standby RECs. In addition, when one end REC fails, the RE service can be processed by the other end REC, which improves the reliability of the service. For example, when one end REC fails, the RE corresponding to the REC can be reversed, so that the service of the RE is processed by the other end REC. Another embodiment of the present invention provides a method for switching a RE service, and the process shown in FIG. 5 is taken as an example, including the following steps:

Step 60: The RE receives an SSI message.

In this embodiment, the SSI message may be an SSI message continuously sent by the primary REC or the standby REC along with the CPRI basic frame.

Step 61: Determine whether the value of the SSI in the SSI message is greater than a specified value;

If the value of the SSI is greater than the specified value, step 62 is performed;

If the value of the SSI is less than or equal to the specified value, step 63 is performed;

Step 62: Determine whether the port that the RE accesses the REC is consistent with the port that receives the SSI message, and subtracts the SSI value by a specific value and transmits the value to the next-level device.

The specific value and the value of the specified value satisfy the following requirements: After the operation of subtracting the specific value from the SSI value is performed N times, the SSI value is less than or equal to the specified value, where N is a positive integer, and the RE of the REC expectation service The number is the same.

If the port where the RE accesses the REC is inconsistent with the port that receives the SSI message, perform the step.

64;

If the port that the RE accesses the REC is the same as the port that receives the SSI message, step 65 is performed; Step 63: The switchover is not performed, and the SSI message is transmitted to the next-level device.

The SSI value of the SSI message sent by the general REC is greater than the specified value. Alternatively, if the SSI value is less than the specified value, the SSI value may be processed in the same manner as the SSI value is equal to the specified value, that is, The SSI message is directly transmitted to the next level device without switching. Step 64: Perform an access port switching.

Step 65: The switching of the access port is not performed.

The embodiment of the present invention implements that the SSI value of the SSI message that can be sent by the RE can be judged whether the operation of the RE is performed, so that the active and standby RECs can share the service of the RE according to their own capabilities. In addition, when one end REC fails, the service of the RE can be processed by the other end REC, which improves the reliability of the service.

As an optional embodiment, in step 62, the operation of transmitting the SSI value to a specific value may be performed without performing a specific value, and correspondingly, the SSI value is subtracted from a specific value and then transmitted to the SSI value. The operation of the next level device can be performed at step 64 or 65.

Since the transmission speed of the SSI message between the REs is very fast, it is almost millisecond or faster. Therefore, in actual applications, the time difference between the RES messages sent by the REs received by the primary RECs and the standby RECs can be neglected. Each RE will process the SSI sent by the primary REC and the standby REC at the same time. To avoid the phenomenon that the SSI message of the primary and backup RECs is frequently switched, the method of the present invention provides a method for switching the RE service. As shown in FIG. 6, the following steps are included:

Step 70: The RE receives the SSI message sent by the primary REC from the first port, and receives the SSI message sent by the standby REC from the second port.

Step 71: Determine whether an SSI message with an SSI value greater than a specified value exists in the first SSI message and the second SSI message;

If yes, go to step 72;

If not, go to step 77;

Step 72: Determine whether the number of SSI messages whose SSI value is greater than a specified value is one;

If no, that is, the number of SSI messages whose SSI value is greater than the specified value is two, then step 73 is performed;

If yes, that is, the number of SSI messages whose SSI value is greater than the specified value is one, step 74 is performed; Step 73: The RE does not perform the access port switching, and the SSI values greater than the specified value are subtracted from a specific value and then transmitted to the next-level RE;

Step 74: Determine whether the port that the RE accesses the REC is consistent with the port that receives the SSI message whose SSI value is greater than the specified value, and subtracts the SSI value by a specific value and transmits the SSI value to the next-level device.

If the port that the RE accesses the REC does not match the port that receives the SSI message whose SSI value is greater than the specified value, step 75 is performed;

If the port of the RE accessing the REC is the same as the port receiving the SSI message whose SSI value is greater than the specified value, step 76 is performed;

Step 75: Perform an access port switching.

Step 76: The switching of the access port is not performed.

Step 77: The switching of the access port is not performed, and the SSI message is transmitted to the next-level device.

In this embodiment, for an RE, if the value of the SSI in the two received SSI messages is greater than the specified value, no switching is performed. If only one SSI value is greater than the specified value, the port and the receiving REC are received. The switch of the SSI message whose SSI value is greater than the specified value is inconsistent, and the active and standby RECs can share the service of processing the RE according to its own capability, and avoid the problem of repeated switching when the RE processes multiple SSI messages. . In addition, when one end REC fails, the RE's service can be processed by the other end REC, which improves the reliability of the service.
