Description

Method, equipment and system for configuring network resources

Technical Field

The present invention relates to mobile communications technologies, and in particular, to a method, an apparatus, and a system for configuring network resources.

Background

The modem technology is one of key technologies in the field of mobile communication, and the HSDPA (High Speed downlink packet Access) technology is a key technology in a WCDMA (Wideband Code division multiple Access) system, and can enhance the throughput of downlink non-real-time packet services and improve the spectrum efficiency of a wireless Access side. The HSDPA technology can achieve higher transmission rate, better support the streaming media type service and meet the requirement of asymmetry of uplink and downlink data services.

HSDPA technology introduces three channels: HS-SCCH (High Speed Shared Control Channel), HS-PDSCH (High Speed Physical Downlink Shared Channel), and HS-DPCCH (High Speed Dedicated Physical Control Channel). The HS-PDSCH is used for bearing high-speed downlink user data information; the HS-SCCH is used for carrying signaling required by demodulating the HS-PDSCH of the accompanying data channel; the HS-DPCCH is used for carrying information for feeding back whether data carried on the HS-PDSCH is received correctly or not, and feeding back CQI (Channel Quality Indication) information.

In order to further enhance the wireless performance of HSDPA, high-order modulation techniques (for example, 16QAM (quadrature amplitude modulation) and 64QAM (quadrature amplitude modulation) are introduced into HSDPA, a Multiple-input-Multiple-output (MIMO) technique, and the like.

MIMO technology is directed to multipath wireless channels, which means that multiple transmitting antennas and multiple receiving antennas are used at the transmitting end and the receiving end, respectively, and the channel capacity increases linearly as the number of antennas increases. Therefore, the wireless channel capacity can be increased by a multiple by using the MIMO technique, and the spectrum utilization ratio can be increased by a multiple without increasing the bandwidth and the antenna transmission power. 64QAM is a high order modulation technique that can provide higher data rates and can more efficiently utilize bandwidth.

In WCDMA systems, 64QAM and MIMO techniques have been introduced in the downlink direction. For example, a UE (user equipment) may support 64QAM and MIMO modes, respectively; an RNC (Radio Network Controller) can support 64QAM and MIMO modes separately or simultaneously; node B (radio frequency transceiver) may support 64QAM and MIMO modes separately or simultaneously.

Before the mobile communication technology is further developed, the UE can only support 64QAM or MIMO technology alone, i.e., the UE can use either 64QAM technology or MIMO technology, and cannot support the combination of the two technologies. In cooperation with the UE, the Node B may support 64QAM technology, may also support MIMO technology, but may not support a mode combining the two technologies.

With the development of mobile communication technology, 64QAM and MIMO technology are beginning to be used jointly. The combination of these two techniques may lead to higher data rates, greater channel capacity, and support for more traffic types. Therefore, the UE, RNC and NodeB are beginning to develop towards supporting the combination of 64QAM and MIMO technologies.

In the process of implementing the invention, the inventor finds that: in a mobile communication network, the development and replacement of UE, RNC and Node B may not be completely synchronized, that is, there may be some mismatch in communication capability among UE, RNC and Node B, in which case, RNC may perform wrong configuration on Node B, and Node B may not correctly understand the wrong configuration and cannot perform correct configuration. At this time, the Node B may cause the failure of the radio link establishment by feeding back the failure information. Due to the failure of radio link establishment, the UE is completely unable to establish a connection with the Node B, and thus unable to use the network. If the Node B does not feed back the failure information but performs configuration according to the wrong information, the problem of communication confusion between the UE and the network side may occur, so that the UE may not normally use the network, and the network quality and the use of the mobile communication user may be seriously affected.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

The present invention proposes a plurality of embodiments, which will be described in detail below. It should be noted that the RNC and the Node B mentioned in the embodiments of the present invention are only an example, and may also be other similar radio network control devices and radio transceiver devices. The 64QAM mentioned in the embodiments of the present invention is only an example, and other similar modulation and demodulation techniques may be used.

Since the UE and the radio access network device may have a mismatch in communication capability, for example, whether a combination of 64QAM and MIMO technology is supported, the UE may not use the network in some cases, and may also cause confusion of network-side communication.

When the UE only supports 64QAM or MIMO technology, the UE can normally use the network no matter whether the RNC and the Node B support the 64QAM and MIMO combined mode. Because, the UE only reports support of 64QAM or support of MIMO during the capability reporting process, and the RNC only notifies the Node B to communicate according to the 64QAM or MIMO mode when allocating the Node B resources according to the capability reported by the UE. The Node B is generally capable of supporting the above two modes, so that communication can be successfully established with the UE according to the mode configured by the RNC.

When the UE supports the mode of combining 64QAM and MIMO, if the RNC does not support the mode of combining two technologies, the UE can normally use the network no matter whether the Node B supports the mode of combining two technologies or not. When the capability reported by the UE to the RNC is a mode supporting the combination of 64QAM and MIMO, the RNC selects a 64QAM or MIMO mode to configure the NodeB according to a general algorithm. Therefore, the Node B only needs to communicate with the UE in 64QAM or MIMO mode, and no confusion occurs.

However, when the UE supports the 64QAM and MIMO combined mode and the RNC also supports the 64QAM and MIMO combined mode, if the Node B supports both the 64QAM and MIMO modes but does not support the two-technology combined mode, a problem may occur in that the UE cannot use the network. The reason for the confusion between the UE and the network will be specifically analyzed.

In a mobile communication network, the RNC may know the capabilities of the Node B. The RNC can make a clear whether the Node B can support the 64QAM or MIMO mode through the learned capability of the Node B. However, when reporting the capability, the Node B reports whether 64QAM is supported or MIMO mode independently, and does not report whether 64QAM and MIMO are supported in a combined manner. Therefore, when the Node B supports both 64QAM and MIMO modes, the RNC cannot clearly know whether the Node B supports the 64QAM and MIMO combined mode according to the reported capability information. Meanwhile, since the RNC supports the 64QAM and MIMO combined mode, the RNC may misjudge that the Node B supports the 64QAM and MIMO combined mode according to the capability reported by the Node B.

When the RNC misjudges that the Node B supports the 64QAM and MIMO combined mode, as shown in fig. 1, when the UE supporting the combination of 64QAM and MIMO establishes a connection with the network, the UE may not use the network. Since the UE supports the 64QAM and MIMO combined mode, the UE will definitely report the 64QAM and MIMO combined mode in the capability information reported to the RNC, and in fig. 1, the 64QAM + MIMO combined mode is represented by 64QAM + MIMO. For example, when an RRC (Radio Resource Control) connection is established between the UE and the RNC, the UE reports its capability to the RNC, where the type of the UE is Category19 or Category20, which indicates that the UE supports a 64QAM and MIMO combined mode.

By synchronizing Node B configuration and logical resource state with RNC, RNC has already learned Node B capabilities, but in the above case, misjudges the mode that Node B supports the combination of 64QAM and MIMO. The RNC can configure the resources of the Node B according to the reported capability of the UE, and instruct the Node B to establish connection with the current UE in a mode of combining 64QAM and MIMO for communication. For example, after the RNC establishes RRC connection with the UE, the RNC performs RL (Radio Link) reconfiguration to instruct the Node B to use a 64QAM and MIMO combined mode for the current UE.

At this time, the Node B may not understand the configuration information of the RNC and may send an error message to the RNC, which may result in a failure in establishing the radio link. The RNC may inform the UE that the radio link establishment fails and that the UE cannot establish communication with the NodeB. Therefore, the UE cannot use the network and cannot perform wireless communication.

When the RNC configures the Node B with the 64QAM and MIMO combined mode, the Node B may also configure the 64QAM and MIMO mode for the current UE radio link according to the instruction of the RNC. However, in the mode where 64QAM is configured alone and MIMO is configured alone, the HS-SCCH and HS-DPCCH channel coding formats are different and the CQI reference table is also different, compared with the mode where 64QAM and MIMO are combined. Therefore, when the Node B simultaneously configures 64QAM and MIMO for the UE supporting the 64QAM and MIMO combined mode, the Node B may not understand or understand the information incorrectly when the UE reports the CQI, and the change of the HS-SCCH channel coding format may also cause the Node B to understand incorrectly or not understand the information of the UE. Therefore, in the above situation, the Node B and the UE cannot correctly understand the information of each other, which may cause the UE to communicate with the network side in a disordered manner, and the UE may not normally use the network.

The resource allocation method of the radio access network shown in fig. 2 can make the RNC clearly and correctly know the capability, configuration and logic resource status of the Node B, and therefore the RNC can correctly perform resource allocation.

The resource allocation method of the wireless access network comprises the following steps:

step 201, RNC sends resource audit request to Node B, starts resource audit process. The RNC sends the resource auditing request, wherein the RNC receives the auditing request indication sent by the Node B, thereby sending the resource auditing request. For example, as shown in fig. 3, the RNC sends a message audio Request to Node B, and sets the information element Start of audio Sequence in the audio Request to Start of audio Sequence or notstart of audio Sequence to Start a new Audit Sequence number, or does not Start a new Audit Sequence number, and only completes the part of the Audit which is not completed.

Step 202, the RNC receives the resource audit response sent by the Node B, and obtains the configuration condition of the Node B and the information such as the state of the logic resource through the resource audit response sent by the Node B. Accordingly, the RNC completes the synchronization of Node B configuration and logic resource state with the Node B. The resource audit response sent by the Node B includes the capability information of the Node B, namely whether the 64QAM mode is supported, whether the MIMO mode is supported and whether the mode combining the 64QAM and the MIMO is supported. For example, as shown in fig. 3, the RNC receives resource Audit Response information Audit Response (Audit Response) sent by the Node B. The audioresponse Information includes 3 IEs (Information elements) respectively indicating that the Node B supports a 64QAM mode, supports a MIMO mode, and does not support a mode in which 64QAM and MIMO are combined. And the RNC learns that the Node B does not support a 64QAM and MIMO combined mode according to the received resource audit response, and completes the synchronization of resource configuration.

Step 203, when the UE initiates a call, the RNC receives the capability information reported by the UE, and learns the capability of the UE accordingly, and after learning the capability of the UE, the RNC configures the resource of the Node B for the current UE according to the capability of the UE and the capability of the Node B, so as to establish communication between the UE and the Node B.

In step 202 the RNC has completed synchronization with the Node B and has explicitly learned the Node B capabilities, configuration and logical resource status. In step 203, if the capability of the UE does not match the capability of the Node B, a mode that the Node B can support is selected for configuration. The mismatch between the UE capability and the Node B capability means that the Node B cannot support the mode supported by the UE, for example, the UE supports a 64QAM and MIMO combined mode but the Node B does not support.

For example, the UE initiates a call request, sends partial capability information in an RRC connection request sent by the UE to the RNC, and sends remaining capability information in a message that RRC connection setup is complete. The UE includes the type of the UE in the capability information of the reporting RNC, for example, Cat19 or Cat20, which indicates that the UE supports a 64QAM and MIMO combined mode and also supports a 64QAM mode and a MIMO mode. And after receiving the capability information reported by the UE, the RNC sends an RL reconfiguration request to the Node B. Since the RNC has explicit knowledge that the Node B supports the 64QAM mode and the MIMO mode but does not support the 64QAM and MIMO combined mode and the UE supports the 64QAM and MIMO combined mode, in this RL reconfiguration request, the RNC configures the Node B to establish communication with the UE in the 64QAM mode or to establish communication with the UE in the MIMO mode.

Step 204, after the RNC completes the configuration of the Node B, the UE is configured according to the configuration of the Node B, so as to complete the synchronization of the UE and the Node B resources. For example, if the Node B is configured to be in the MIMO mode by the RNC in the RL reconfiguration request, the RNC configures the UE to establish communication in the MIMO mode through the radio bearer establishment information according to the configuration of the Node B.

According to the above embodiment, when the RNC synchronizes the capability, configuration condition and logic resource state of the Node B with the Node B, the resource audit response information sent by the Node B includes the IE of whether the Node B supports the 64QAM and MIMO combined mode, so that the RNC can definitely know whether the Node B supports the 64QAM and MIMO combined mode, and will not configure the combined mode for the Node B when the Node B does not support the mode. Therefore, the situation that the Node B cannot establish a wireless link due to the wrong configuration of the Node B by the RNC can not occur. At this time, the Node B can successfully establish a radio link, and the UE can normally use the network. Meanwhile, when the RNC configures the Node B and the UE, the resource of the Node B and the UE can be synchronized, the phenomenon that the Node B and the UE do not understand or wrongly understand the information of each other can be avoided, the communication confusion between the UE and the network side can be avoided, and the UE can normally use the network.

The radio access network resource allocation method shown in fig. 4 can also solve the problems in the prior art. The method for configuring the resources of the wireless access network comprises the following steps:

step 401, the RNC receives the resource status indication information sent by the Node B, and synchronizes the capability, configuration and logic resource status of the Node B with the Node B accordingly. The resource status indication sent by the Node B includes capability information of the Node B, i.e. whether the 64QAM mode is supported, whether the MIMO mode is supported, and whether the 64QAM and MIMO combined mode is supported. For example, as shown in fig. 5, a Node B sends resource status indication information to an RNC, where the information includes 3 IEs indicating that the Node B supports a 64QAM mode, supports a MIMO mode, and does not support a 64QAM and MIMO combined mode. Wherein, the Node B sending the resource status indication information to the RNC may be when any one of the following occurs: adding the local cell of the Node B, namely when the local cell state becomes existent; deleting the local cell of the Node B, namely when the state of the local cell is changed to be nonexistent; when the capability of the local cell changes; when the cell capability and/or resource operation state of the Node B is changed; when the capability of the public physical channel and/or the public transmission channel of the Node B is changed; when the running state of the communication control port resource of the Node B is changed; when the local cell group resource capability of the Node B changes.

And the RNC acquires that the Node B does not support a 64QAM and MIMO combined mode according to the received resource state indication to complete the synchronization of the resource configuration.

Step 402, when UE initiates a call, RNC receives capability information reported by UE, and learns the capability of UE accordingly, after learning the capability of UE, RNC configures the resource of Node B for the current UE to establish the communication between UE and Node B.

For example, the UE initiates a call request, sends partial capability information in an RRC connection request sent by the UE to the RNC, and sends remaining capability information in a message that RRC connection setup is complete. The UE includes the type of the UE in the capability information of the reporting RNC, for example, Cat19 or Cat20, which indicates that the UE supports a 64QAM and MIMO combined mode and also supports a 64QAM mode and a MIMO mode. And after receiving the capability information reported by the UE, the RNC sends an RL reconfiguration request to the Node B. In step 401, the RNC has completed synchronization with the Node B and has explicitly learned the capability, configuration and logical resource status of the Node B. Therefore, the RNC has clear knowledge that the Node B supports the 64QAM mode and the MIMO mode, but does not support the combined 64QAM and MIMO mode, so in this RL reconfiguration request, the RNC configures the Node B to establish communication with the UE in the 64QAM mode or to establish communication with the UE in the MIMO mode.

Step 403, after the RNC completes the configuration of the Node B, the RNC configures the UE according to the configuration of the Node B to complete the synchronization of the UE and the Node B resources. For example, the RNC configures the Node B in the RL reconfiguration request to the 64QAM mode, and the RNC configures the UE to establish communication in the 64QAM mode through the radio bearer setup information according to the configuration of the Node B.

According to the above embodiment, when the RNC synchronizes the capability, configuration situation and logic resource state of the Node B with the Node B, the resource state indication information sent by the Node B includes the IE of whether the Node B supports the 64QAM and MIMO combined mode, so the RNC can clearly know whether the Node B supports the 64QAM and MIMO combined mode, and will not configure the combined mode for the Node B when the Node B does not support the mode. Therefore, the situation that the Node B cannot establish a wireless link due to the wrong configuration of the Node B by the RNC can not occur. At this time, the Node B can successfully establish a radio link, and the UE can normally use the network. Meanwhile, when the RNC configures the Node B and the UE, the resource of the Node B and the UE can be synchronized, the phenomenon that the Node B and the UE do not understand or wrongly understand the information of each other can be avoided, the communication confusion between the UE and the network side can be avoided, and the UE can normally use the network.

The Node B in the above embodiment of the present invention is shown in fig. 6, and includes a processing module and a transceiver module. The transceiver module is used for receiving information sent by other equipment and/or sending information to other equipment. For example, when information interaction is performed with the RNC, information is transmitted and received. The processing module is used for determining the information content sent to the RNC according to the self condition of the equipment. For example, when Node B sends resource audit response to RNC, the processing module informs the transceiver module to send corresponding IE to RNC according to whether this Node B can support 64QAM mode, whether it can support MIMO mode and whether it can support 64QAM and MIMO combined mode. After receiving the IE indicating the Node B support mode sent by the transceiver module, the processing method of the RNC is the same as that in the above embodiment, and is not described herein again.

In addition, the processing module of the Node B shown in fig. 6 may also be configured to, when the Node B sends the resource status indication information to the RNC, notify the transceiver module to send the corresponding IE to the RNC according to whether the Node B can support the 64QAM mode, whether the Node B can support the MIMO mode, and whether the Node B can support the 64QAM and MIMO combined mode.

The system of the above embodiment of the present invention is shown in fig. 7. The UE requests to RNC to establish connection, reports the UE capability, establishes connection with Node B according to the configuration of RNC to the UE, and the like. The Node B is used for synchronizing the capability, the configuration condition and the logic resource state of the Node B with the RNC through a resource auditing process and/or resource state indicating information and establishing connection with the UE according to the configuration of the RNC. The RNC is used for receiving the request of establishing connection of the UE, receiving the capability information reported by the UE, carrying out resource synchronization with the Node B, and carrying out resource configuration on the Node B and the UE according to the capabilities of the Node B and the UE. Wherein Node B is the Node B shown in FIG. 6.

In the system shown in fig. 7, Node B and RNC are synchronized irregularly according to Node B status and event trigger, and Node B capability, configuration and logic resource status are synchronized. For example, in the resource auditing process and/or the resource status indication information, the resource synchronization of the RNC and the NodeB is performed. When UE needs to establish connection, it sends request of establishing connection to RNC and reports the capability information of UE, RNC carries out resource allocation to Node B according to the reported information of UE and the capability of Node B. When UE supports 64QAM and MIMO combined mode, if Node B only supports 64QAM mode and MIMO mode, RNC selects configuring Node B according to 64QAM or MIMO mode, and configuring UE to same mode. Therefore, the RNC can clearly know the capability of the Node B, so the Node B can be configured according to the capability reported by the UE while considering the capability of the Node B, the condition that the configuration of the Node B by the RNC is different from the capability of the Node B can not occur, the Node B can successfully establish a wireless link, and the UE can normally use the network. Meanwhile, the Node B and the UE are configured with the same mode, so that the connection can be smoothly established, and the UE can normally use the network.

The method for configuring radio access network resources as shown in fig. 8 can also solve the problems in the prior art. The method for configuring the resources of the wireless access network comprises the following steps:

step 801, when the UE initiates a call, the RNC receives a connection establishment request of the UE and reported capability information, and accordingly obtains the capability of the UE, for example, the UE supports a 64QAM and MIMO combined mode.

Step 802, after learning the capability of the UE, the RNC configures the resource of the Node B for the current UE according to the capability of the UE and the capability of the Node B, so as to establish communication between the UE and the Node B. For example, the RNC learns that the Node B can support the 64QAM mode and the MIMO mode through two independent IEs reported by the Node B in the previous synchronization with the Node B, and thus misjudges that the Node B supports the 64QAM and MIMO combined mode. The capability reported by the UE is a mode supporting the combination of 64QAM and MIMO, so the RNC can configure the mode of combining 64QAM and MIMO for the Node B for the current UE.

Step 803, after the RNC configures the Node B, if there is a situation that the Node B capabilities are not matched, the Node B selects the supported mode by itself and reports it to the RNC. The mismatching of the resource configuration of the RNC to the Node B and the self capability of the Node B means that the resource Node B configured by the RNC can not be realized. For example, the RNC configures the Node B in a mode combining MIMO and 64QAM, but the Node B does not support the mode combining 64QAM and MIMO, which is the case where the configuration of the Node B by the RNC is not matched with the capability of the Node B. And the RNC configures the UE according to the information fed back by the Node B. For example, the RNC configures the Node B with a mode in which the Node B is combined with 64QAM and MIMO for the current UE, but the Node B does not support the combined mode, so the Node B selects the mode 64QAM that can be supported by itself or configures the Node B with MIMO, and reports the adopted mode to the RNC. And the RNC configures the UE into the same mode as the Node B according to the information fed back by the Node B so as to facilitate the UE and the Node B to establish communication.

According to this embodiment, although the RNC cannot completely and correctly know the capability of the Node B when synchronizing the capability, configuration condition and logic resource state of the Node B with the Node B, for example, when the Node B supports both the 64QAM mode and the MIMO mode, the RNC cannot know whether the Node B supports the 64QAM and MIMO combined mode, but when the RNC misjudges that the Node B supports the 64QAM and MIMO combined mode and configures the Node B accordingly, the Node B can select to adopt the 64QAM or MIMO mode and feed back the mode to the RNC, which will not cause the failure of the radio link establishment directly due to the wrong configuration, and the UE can still use the network normally. And the RNC can still enable the resource allocation of the UE and the Node B to be consistent under the condition of misjudgment. Therefore, the UE and the Node B can correctly understand the information of each other and establish normal communication, so the UE can normally and effectively use the network.

The Node B used in the above embodiments is shown in fig. 6, and includes a processing module and a transceiver module. The transceiver module is used for receiving information sent by other equipment and/or sending information to other equipment. For example, the transceiver module receives configuration information sent by the RNC and sends feedback information to the RNC. The processing module is used for confirming whether the configuration information sent by the RNC is matched with the capability of the Node B, and if not, selecting the matched capability for configuration. For example, when the RNC requests the Node B to configure a 64QAM and MIMO combined mode, and the processing module determines that the Node B does not support the 64QAM and MIMO combined mode, the processing module selects 64QAM or MIMO configures the Node B, and feeds back the specific mode adopted by the RNC Node B through the transceiver module. Therefore, when the configuration of the Node B is not matched with the self capability, the wireless link establishment failure can not be caused, and the RNC can configure the UE according to the information fed back by the Node B and enables the mode adopted by the UE to be the same as that of the Node B, thereby realizing the normal use of the network by the UE.

The system of the above embodiment of the present invention is shown in fig. 7. The UE requests to RNC to establish connection, reports the UE capability, establishes connection with Node B according to the configuration of RNC to the UE, and the like. The Node B is used for synchronizing the capability, the configuration condition and the logic resource state of the Node B with the RNC, when the received configuration information is not matched with the capability of the Node B, the matched capability is selected for configuration, the configuration condition is fed back to the RNC, and the connection with the UE is established according to the configuration. The RNC is used for receiving the request of establishing connection of the UE, receiving the capability information reported by the UE, carrying out resource synchronization with the Node B, and carrying out resource configuration on the Node B and the UE according to the capabilities of the Node B and the UE. Wherein the NodeB is the Node B as shown in fig. 6.

In the system shown in fig. 7, Node B and RNC are synchronized irregularly according to Node B state and event trigger, and Node B capability, configuration and logic resource state are synchronized. For example, in the resource auditing process and/or the resource status indication information, the resource synchronization of the RNC and the Node B is carried out. However, in the process of synchronizing the RNC with the Node B, if the Node B supports both 64QAM and MIMO modes, the RNC may consider that the Node B supports the 64QAM and MIMO combined mode. When UE needs to establish connection, it sends request of establishing connection to RNC and reports the capability information of UE, RNC carries out resource allocation to Node B according to the reported information of UE and the capability of Node B. When the Node B confirms that the configuration information sent by the RNC is not matched with the capability of the Node B, the Node B selects a mode matched with the capability of the Node B to configure and feeds back the mode to the RNC. For example, the RNC configures the Node B to adopt a 64QAM and MIMO combined mode, but the Node B does not support the combined mode, the Node B selects the 64QAM or MIMO mode for configuration and feeds back to the RNC the mode adopted by the Node B. Therefore, the Node B does not cause radio link establishment failure due to mismatch between the configuration and the capability of the Node B, and the UE can normally use the network. Meanwhile, the RNC configures the UE according to the mode fed back by the Node B, so that the UE and the Node B are consistent in configuration, the Node B and the UE can understand the information of each other, the communication between the UE and the network side is not disordered, and the UE can normally use the network.

The radio access network resource allocation method shown in fig. 9 can also solve the problems in the prior art. The method for configuring the resources of the wireless access network comprises the following steps:

step 901, when the UE initiates a call, the RNC receives a connection establishment request of the UE and reported capability information, and accordingly obtains the capability of the UE, for example, the UE supports a 64QAM and MIMO combined mode.

Step 902, after obtaining the capability of the UE, the RNC configures the resource of the Node B for the current UE according to the capability of the UE and the capability of the Node B, so as to establish communication between the UE and the Node B. For example, in the previous synchronization with the Node B, the RNC learns that the Node B can support the 64QAM mode and the MIMO mode through two independent IEs reported by the Node B, and thus misjudges that the Node B supports the 64QAM and MIMO combined mode, and the capability reported by the UE is the 64QAM and MIMO combined mode, so that the RNC configures the Node B with the 64QAM and MIMO combined mode for the current UE.

Step 903, after the RNC configures the Node B, if there is a situation that the Node B capabilities are not matched, the Node B returns a configuration failure and a failure reason to the RNC. The RNC takes further action according to the information fed back by the Node B. Further actions may be, for example, the RNC selecting an appropriate configuration according to the failure reason of the feedback, and reconfiguring; or the RNC completes the synchronization of the Node B resources according to the failure reason fed back, feeds back the UE to establish communication failure, and re-initiates the call. For example, the RNC configures the Node B with a mode in which the Node B is combined with 64QAM and MIMO for the current UE, but the Node B does not support the combined mode, and therefore, the Node B returns information of a configuration failure and a failure reason, where the failure reason is that the combined mode of 64QAM and MIMO is not supported. At this time, the RNC may reconfigure the Node B to be in the 64QAM mode or the MIMO mode according to the failure reason fed back by the Node B. At this time, although the Node B returns a configuration error, it will not cause a failure of the final radio link establishment, so the UE can still use the network normally.

After receiving the failure reason fed back by the Node B, the RNC can also resynchronize the capability of the Node B according to the failure reason, and at this time, the RNC definitely knows that the Node B does not support the 64QAM and MIMO combined mode, and informs the UE that the connection fails at this time, and the call is reinitiated. At this time, although the radio link is failed to be established because the Node B cannot perform the configuration that does not match the capability, the RNC does not perform the wrong configuration on the Node B any more when the radio link is re-established next time, and the radio link can be successfully established, so the UE can still use the network normally.

The RNC can make the resource allocation of the UE and the Node B consistent by adopting the further processing method, thereby understanding the mutual information, not causing the communication confusion of the UE and the network side, and enabling the UE to normally use the network.

The Node B used in the above embodiments is shown in fig. 6, and includes a processing module and a transceiver module. The transceiver module is used for receiving information sent by other equipment and/or sending information to other equipment. For example, the transceiver module receives configuration information sent by the RNC and sends feedback information to the RNC. The processing module is used for confirming whether the configuration information sent by the RNC is matched with the capability of the Node B, and if not, sending configuration failure information and a failure reason to the RNC through the transceiving module. For example, when the RNC requests the Node B to configure the 64QAM and MIMO combined mode, and the processing module determines that the Node B does not support the 64QAM and MIMO combined mode, the processing module sends the configuration failure information and the failure reason to the RNC through the transceiver module, where the failure reason is that the Node B does not support the 64QAM and MIMO combined mode. Therefore, the RNC can reconfigure the UE or resynchronize and wait for the call again according to the information fed back by the Node B. The two processing modes can successfully establish a wireless link and make the mode adopted by the UE the same as that of the Node B, thereby realizing that the UE normally uses the network.

The system of the above embodiment of the present invention is shown in fig. 7. The UE requests to RNC to establish connection, reports the UE capability, establishes connection with Node B according to the configuration of RNC to the UE, and the like. The Node B is used for synchronizing the capability, the configuration condition and the logic resource state of the Node B with the RNC, and when the received configuration information is not matched with the capability of the Node B, the failure of configuration and the failure reason are fed back to the RNC and connection is established with the UE according to the configuration. The RNC is used for receiving a request for establishing connection of the UE, receiving capability information reported by the UE, synchronizing resources with the Node B, configuring the resources of the Node B and the UE according to the capabilities of the Node B and the UE, and reconfiguring the Node B according to a failure reason or synchronously waiting for the UE to call again after the Node B returns the failure reason. Wherein the NodeB is the Node B as shown in fig. 6.

In the system shown in fig. 7, Node B and RNC are synchronized irregularly according to Node B state and event trigger, and Node B capability, configuration and logic resource state are synchronized. For example, in the resource auditing process and/or the resource status indication information, the resource synchronization of the RNC and the Node B is carried out. However, in the process of synchronizing the RNC with the Node B, if the Node B supports both 64QAM and MIMO modes, the RNC may consider that the Node B supports the 64QAM and MIMO combined mode. When UE needs to establish connection, it sends request of establishing connection to RNC and reports the capability information of UE, RNC carries out resource allocation to Node B according to the reported information of UE and the capability of Node B. When the Node B confirms that the configuration information sent by the RNC is not matched with the capability of the Node B, the Node B feeds back the failure of configuration and the failure reason to the RNC. For example, if the Node B configured by the RNC adopts a 64QAM and MIMO combined mode, but the Node B does not support the combined mode, the Node B feeds back the failure configuration to the RNC and the failure reason is that the Node B does not support the 64QAM and MIMO combined mode. The RNC can definitely know that the Node B does not support the 64QAM and MIMO combined mode according to the feedback of the Node B, and informs the UE that the connection fails at this time, and the call is initiated again. The RNC may also reconfigure the Node B according to the feedback of the Node B, configure it into 64QAM or MIMIO mode, and configure the UE according to the same mode. Both methods can successfully establish a wireless link, thereby ensuring that the UE normally uses the network. Meanwhile, the RNC is consistent with the configuration of the UE and the Node B, the Node B and the UE can understand the information of each other, the communication confusion between the UE and the network side is not caused, and the UE can normally use the network.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
