Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 shows an embodiment of a multi-carrier power adjustment method according to the present invention. The multicarrier power adjustment method of the embodiment comprises the following steps:

step S10, when the radio network controller RNC establishes the public transmission channel, the transmitting power of the preset channel is set as the minimum value of the standard protocol, and the system information updating request only contains the preset information;

in this embodiment, a plurality of UMTS (Universal Mobile Telecommunications System) carriers are deployed in one sector. The plurality of UMTS carriers include an access carrier frequency and a simplified carrier frequency, wherein the access carrier frequency is a wide coverage carrier frequency for the user terminal to reside and access the service only in the carrier frequency, and the access carrier frequency may be a wide coverage carrier frequency for carrying the voice service. The type of the user terminal can be set according to actual needs, and can be a mobile phone, a computer and the like. The simplified carrier frequency is a carrier frequency of non-resident and non-access service, and the simplified carrier frequency may be a capacity-expanded carrier frequency for carrying data service.

When a public transmission channel sent to a base station NodeB by a Radio Network Controller (RNC) through NBAP signaling is established, the transmitting power of a preset channel is set to be the minimum value of a standard protocol, so that the preset channel is sent with the minimum transmitting power, and the transmitting power occupied by the public channel is reduced. The preset Channel may include an AICH (Acquisition Indication Channel), a PICH (Paging Indication Channel), a FACH (Forward Access Channel), and a PCH (Paging Channel), and may also be flexibly set according to specific situations. .

And the radio network controller RNC only sends preset information in a system information updating request sent to the base station NodeB through the NBAP signaling. The preset Information may include MIB (Master Information Block), SIB1 (systeminformationblock 1), and SIB3 (systeminformationblock 3 ). It is understood that the preset information can be flexibly set according to specific situations. It should be noted that, when the system information update request is sent, the radio network controller RNC sends the broadcast message at intervals of a preset time, where the preset time may be set to 80 milliseconds, and may also be flexibly set according to specific situations. Meanwhile, only relevant necessary information elements are filled in each transmitted information block so as to reduce the transmission of broadcast messages.

Step S20, the base station NodeB configures the non-camping simplified carrier frequency according to the received common transport channel establishment and system information update request.

When the base station NodeB receives the establishment of the public transmission channel sent by the radio network controller RNC, the transmitting power of the preset channel is set to be the minimum value allowed by the standard protocol, and the sent system information updating request only contains preset information, the radio network controller RNC is considered to start the multi-carrier power optimization function. At this time, the base station NodeB configures the non-camping simplified carrier frequency according to the received system information update request. That is, the check of the system information update message allows the simplified carrier frequency to optimize the common Channel power configuration thereof, and meanwhile, the base station NodeB does not reserve power for the BCH (Broadcast Channel). Therefore, the configuration of the public channel is reduced, the transmitting power occupied by the public channel is reduced, the cell broadcasting is simplified, and the sending of the broadcasting information is reduced. At this time, when the telephone traffic is not high, the power consumption of the whole sector can be reduced; on the contrary, when the traffic is high, the saved common channel power can be dynamically scheduled by the HSDPA, thereby increasing the data throughput of the carrier frequency.

Further, in the first embodiment, the configuring, by the base station NodeB, the non-camping reduced carrier frequency according to the received common transport channel setup and system information update request includes: and the cell on the simplified carrier frequency only sends a primary common pilot channel P-CPICH, a synchronization channel SCH and a primary common control physical channel P-CCPCH, and only sends a system frame number SFN and cell block state indication information on a broadcast channel BCH carried by the primary common control physical channel P-CCPCH.

Specifically, only the P-CPICH (Primary Common Pilot Channel), SCH (synchronization Channel), and P-CCPCH (Primary Common Control Physical Channel), which are three Physical channels, may be transmitted to the cell base station NodeB on the reduced carrier frequency. The BCH carried on the P-CCPCH channel only transmits the necessary SFN (System Frame Number), cell block status indication information, and the like, so that the user terminal does not access the simplified carrier frequency where the cell in the block status is located. Meanwhile, the frequency point information of the access carrier frequency can be selected and sent, so that the user terminal can be correctly accessed to the access carrier frequency. In this embodiment, a cell block configuration is performed in advance, and under the block configuration, the cell broadcast message indicates that the cell is in a block state, but the cell is still in a normal working state in network management, no alarm occurs, and normal performance statistics exists. Namely, under the cell block configuration, the cell does not send any broadcast information and cannot access the service, but can normally work, can receive the service accessed by the carrier frequency pilot frequency equalization, and belongs to an incomplete block state.

Further, in the second embodiment, the configuring, by the base station NodeB, the non-camping simplified carrier frequency according to the received common transport channel setup and system information update request includes: and when the broadcast channel BCH is in a null packet state, no information is sent.

In order to save the power of the P-CCPCH channel as much as possible, when there is no BCH information to be transmitted, the base station NodeB performs DTX (Discontinuous Transmission) processing, that is, does not transmit an empty BCH frame. At this time, the broadcast module is in an empty packet state, and does not transmit any broadcast packet nor SFN information. Meanwhile, the base station NodeB does not reserve power for BCH, so that HSDPA can schedule all the residual power.

Further, in the third embodiment, the configuring, by the base station NodeB, the non-camping simplified carrier frequency according to the received common transport channel setup and system information update request includes: and when the current load of the simplified carrier frequency is greater than the preset load, balancing the service carried by the accessed carrier frequency to the simplified carrier frequency.

Aiming at a cell on a simplified carrier frequency, a user terminal cannot reside and access a service in the cell, a Radio Network Controller (RNC) needs to judge the load of the simplified carrier frequency, and if the current load of the simplified carrier frequency is greater than a preset load, the service of the accessed carrier frequency is allowed to be balanced to the load of the simplified carrier frequency. The preset load and the balancing mode can be flexibly set according to actual needs. When accessing the service at the carrier frequency, the service is simplified by the pilot frequency equalization, and the failure rate of the pilot frequency equalization is very low according to the performance statistics of the current network. Therefore, the service connection rate caused by pilot frequency equalization can be borne. Therefore, multiple carriers in one sector are bound into a uniform resource pool, and the service throughput of the whole sector is improved.

Further, in the fourth embodiment, the configuring, by the base station NodeB, the non-camping simplified carrier frequency according to the received common transport channel setup and system information update request includes: and when the access carrier frequency fails, activating all normal channels by the simplified carrier frequency to transmit, and taking the simplified carrier frequency as the access carrier frequency.

In the process of simplifying the service carried by the carrier frequency, if Channel migration to FACH (Forward Access Channel) or PCH (Paging Channel) occurs, it is necessary to indicate the frequency point information of the Access carrier frequency in the state migration message. If service Release occurs and the terminal supports R6(Release 6) protocol, indicating the frequency point information of the access carrier frequency in the Release message, so that the user terminal can know the frequency point information of the access carrier frequency. When the access carrier frequency in the sector is failed, the simplified carrier frequency can activate all normal channels to transmit and become the access carrier frequency, and the user terminal can normally work to perform resident and access services.

In the embodiment of the invention, when a common transmission channel is established, the RNC sets the transmitting power of a preset channel as the minimum value of a standard protocol, and only contains preset information in a system information updating request. Then base station NodeB configures non-resident simplified carrier frequency according to received public transmission channel establishment and system information update request. The preset channel is enabled to transmit with the minimum transmitting power, and therefore the transmitting power occupied by the common transmission channel is reduced. Meanwhile, the system information updating request only contains the preset information, so that the transmission of the broadcast information is reduced. In addition, the simplified carrier frequency is configured, and the power consumption of the sector is further reduced.

Correspondingly, as shown in fig. 2, an embodiment of a multi-carrier power adjustment system according to the present invention is provided. The multi-carrier power adjustment system of this embodiment includes a radio network controller RNC 100 and a base station NodeB 200, where the radio network controller RNC 100 includes:

a setting module 101, configured to set a transmission power of a preset channel to a minimum value of a standard protocol when a common transmission channel is established, where a system information update request only includes preset information;

in this embodiment, a plurality of UMTS (Universal Mobile Telecommunications System) carriers are deployed in one sector. The plurality of UMTS carriers include an access carrier frequency and a simplified carrier frequency, wherein the access carrier frequency is a wide coverage carrier frequency for the user terminal to reside and access the service only in the carrier frequency, and the access carrier frequency may be a wide coverage carrier frequency for carrying the voice service. The type of the user terminal can be set according to actual needs, and can be a mobile phone, a computer and the like. The simplified carrier frequency is a carrier frequency of non-resident and non-access service, and the simplified carrier frequency may be a capacity-expanded carrier frequency for carrying data service.

When the radio network controller RNC 100 establishes the common transmission channel transmitted to the base station NodeB 200 through the NBAP signaling, the setting module 101 sets the transmission power of the preset channel to the standard protocol minimum value, so that the preset channel is transmitted with the minimum transmission power, and the transmission power occupied by the common channel is reduced. The preset Channel may include an AICH (Acquisition Indication Channel), a PICH (Paging Indication Channel), a FACH (Forward Access Channel), and a PCH (Paging Channel), and may also be flexibly set according to specific situations. .

In a system information update request sent by the radio network controller RNC 100 to the base station NodeB 200 through the NBAP signaling, the setting module 101 only sends preset information. The preset Information may include MIB (Master Information Block), SIB1(System Information Block 1), and SIB3(System Information Block 3). It is understood that the preset information can be flexibly set according to specific situations. It should be noted that, when the system information update request is sent, the RNC 100 sends the broadcast message at preset time intervals, where the preset time may be set to 80 milliseconds, or may be flexibly set according to specific situations. Meanwhile, only relevant necessary information elements are filled in each transmitted information block so as to reduce the transmission of broadcast messages.

The base station NodeB 200 includes:

a configuring module 201, configured to configure the non-resident simplified carrier frequency according to the received common transport channel establishment and system information update request.

When the base station NodeB 200 receives the establishment of the common transmission channel sent by the radio network controller RNC 100, the transmission power of the preset channel is set to the minimum value allowed by the standard protocol, and when the sent system information update request only contains preset information, it is considered that the radio network controller RNC 100 starts the multi-carrier power optimization function, and at this time, the base station NodeB 200 calls the configuration module 201 to configure the non-resident simplified carrier frequency according to the received system information update request. I.e. the checking of the system information update message allows simplifying the carrier frequency to optimize its common Channel power configuration, while the base station NodeB 200 does not reserve power for the BCH (Broadcast Channel). Therefore, the configuration of the public channel is reduced, the transmitting power occupied by the public channel is reduced, the cell broadcasting is simplified, and the sending of the broadcasting information is reduced. At this time, when the telephone traffic is not high, the power consumption of the whole sector can be reduced; on the contrary, when the traffic is high, the saved common channel power can be dynamically scheduled by the HSDPA, thereby increasing the data throughput of the carrier frequency.

Further, in the first embodiment, the configuration module 201 is further configured to send, on the simplified carrier frequency, only the primary common pilot channel P-CPICH, the synchronization channel SCH, and the primary common control physical channel P-CCPCH, and send, on the broadcast channel BCH carried by the primary common control physical channel P-CCPCH, only the system frame number SFN and the cell block status indication information.

Specifically, the NodeB 200 may transmit only the P-CPICH (Primary Common Pilot Channel), SCH (synchronization Channel), and P-CCPCH (Primary Common Control Physical Channel) for the cell on the reduced carrier frequency. The BCH carried on the P-CCPCH channel only transmits the necessary SFN (System Frame Number), cell block status indication information, and the like, so that the user terminal does not access the simplified carrier frequency where the cell in the block status is located. Meanwhile, the frequency point information of the access carrier frequency can be selected and sent, so that the user terminal can be correctly accessed to the access carrier frequency. In this embodiment, a cell block configuration is performed in advance, and under the block configuration, the cell broadcast message indicates that the cell is in a block state, but the cell is still in a normal working state in network management, no alarm occurs, and normal performance statistics exists. Namely, under the cell block configuration, the cell does not send any broadcast information and cannot access the service, but can normally work, can receive the service accessed by the carrier frequency pilot frequency equalization, and belongs to an incomplete block state.

Further, in the second embodiment, the configuring module 201 is further configured to not send information when the broadcast channel BCH is in a null packet state.

In order to save the P-CCPCH channel power as much as possible, when there is no BCH information to be transmitted, the base station NodeB 200 performs DTX (Discontinuous Transmission) processing, that is, does not transmit an empty BCH frame. At this time, the broadcast module is in an empty packet state, and does not transmit any broadcast packet nor SFN information. Meanwhile, the base station NodeB 200 does not reserve power for BCH, so that HSDPA can schedule all remaining power.

Further, in the third embodiment, the configuration module 201 is further configured to, when the current load of the simplified carrier frequency is greater than the preset load, balance the service carried by the accessed carrier frequency to the simplified carrier frequency.

For a cell on a simplified carrier frequency, a user terminal cannot reside and access a service in the cell, and the radio network controller RNC 100 needs to determine the load of the simplified carrier frequency, and if the current load of the simplified carrier frequency is greater than a preset load, the service of the accessed carrier frequency is allowed to be balanced to the load of the simplified carrier frequency. The preset load and the balancing mode can be flexibly set according to actual needs. When accessing the service at the carrier frequency, the service is simplified by the pilot frequency equalization, and the failure rate of the pilot frequency equalization is very low according to the performance statistics of the current network. Therefore, the service connection rate caused by pilot frequency equalization can be borne. Therefore, multiple carriers in one sector are bound into a uniform resource pool, and the service throughput of the whole sector is improved.

Further, in the fourth embodiment, the configuration module 201 is further configured to, when the access carrier frequency fails, activate all normal channels to transmit by the simplified carrier frequency, and use the simplified carrier frequency as the access carrier frequency.

In the process of simplifying the service carried by the carrier frequency, if Channel migration to FACH (Forward Access Channel) or PCH (Paging Channel) occurs, it is necessary to indicate the frequency point information of the Access carrier frequency in the state migration message. If service Release occurs and the terminal supports R6(Release 6) protocol, indicating the frequency point information of the access carrier frequency in the Release message, so that the user terminal can know the frequency point information of the access carrier frequency. When the access carrier frequency in the sector is failed, the simplified carrier frequency can activate all normal channels to transmit and become the access carrier frequency, and the user terminal can normally work to perform resident and access services.

In the embodiment of the present invention, when the common transport channel is established, the RNC 100 sets the transmission power of the preset channel to the minimum value of the standard protocol, and the system information update request only includes the preset information. Then, the NodeB 200 configures the non-camping simplified carrier frequency according to the received common transport channel establishment and system information update request. The preset channel is enabled to transmit with the minimum transmitting power, and therefore the transmitting power occupied by the common transmission channel is reduced. Meanwhile, the system information updating request only contains the preset information, so that the transmission of the broadcast information is reduced. In addition, the simplified carrier frequency is configured, and the power consumption of the sector is further reduced.
