Data gathering method in communication system

The present invention relates to a data gathering method in a communication system. In particular, the present invention relates to data gathering in a communication system that can collect transmit power data for frequency transmission (FA) and sector for transmission power monitoring transmitted for each path. It is about a method.

Since a typical base station modem chip has limited use of a three-path transmission path, the shelf responsible for the baseband digital channel is 1FA (one shelf per shelf). Frequency Assignment) -3Sector has been used and is currently in operation according to the control method for 1FA-3Sector per shelf.

However, due to the development of modem chip technology and high integration of hardware, the transmission path of modem chip can be up to 6 paths, and 2FA-3Sector, 1FA-6Sector or 6FA-Omni Sector can be installed per shelf.

Hereinafter, a hardware configuration of a triple path channel transmission combiner and a transmission path of a radio frequency and channel control shelf of a conventional base station will be described with reference to the accompanying drawings.

1 is a hardware configuration diagram of a triple path channel transmission combiner and a transmission path of a radio frequency and channel control shelf of a conventional base station.

The hardware configuration of the three-path channel transmission combiner and the transmission path of the radio frequency and channel control shelf of the conventional base station is, as shown in Figure 1, a plurality of assemblies constituting the base transceiver system of the mobile communication system (Base Transceiver System) A multi-channel processor assembly (hereinafter abbreviated as MCPA) 10 for digital signal processing function of a code division multiple access (CDMA) system under the control of a base station processor (BSP); A radio frequency and channel control processor assembly (hereinafter referred to as RCPA) 20 for performing radio frequency and channel control of the digital signal transmitted from the MCPA 10; 20) Base Station Sector Conversion & Up / Down Convertor Assembly, which converts the frequency of the transmitted signal. 30, the triple path channel transmission combiner is a triple path as three ports of the zero to second path channel transmission combiner ports 21a, 21b, 21c in RCPA 20. A channel transmission combiner 21 is configured.

Here, the MCPA 10 is composed of the 0th to Mth channel cards 11a, 11b, ..., 11m, each of which includes a triple path modem chip, and the BUDA 30 includes the 0th to 2nd BUDA ( 30a, 30b, 30c).

In the prior art having such a configuration, the digital signal received from the 0th to the Mth channel cards 11a, 11b, ..., 11m in the transmission combiner control is transmitted from the 0th to the 2nd path channel transmission combiner port. Are selectively assigned to (21a, 21b, 21c), and each bit (Bit0 to Bit M-1) in the register of the transmission combiner of each path is assigned to M 0th to Mth channel cards 11a, 11b. 11 m).

For example, the zero to second path channel transmission combiner ports 21a, 21b, 21c in the RCPA 20 are enabled to open the output data transmission path of the Mth channel card 11m. To do this, enable the M bit of the combiner register port of all paths P0 to P2 high. Each of these enabled combiners transmits data from the zero to second BUDAs 30a, 30b, and 30c of the three paths.

FIG. 2 is a flowchart illustrating a transmission power collection method of a triple path channel transmission combiner of a radio frequency and channel control shelf as shown in FIG. 1.

In the prior art, the transmission power collection method receives Tx power values transmitted from each channel from all channel cards 41a, 41b, and 41n and collects them for each sector. This is a flowchart of the previous technique.

First, when receiving the transmit power message (TxPwrMsg) from the i-th channel card (S1), the corresponding channel card number i is substituted into the channel number (ChcNum) (ChcNum = i), and the contents of the message for each path of the modem are written. It updates sequentially in its own channel card and path-specific database (Database: DB). Subsequently, the modem path number ModemPathNum, which is a DB index, is initialized and set to 0 for collecting (ModemPathNum = 0) (S2).

Subsequently, the transmission power value (Tx Power) in the message received from the i-th channel card is stored in the channel transmission power (ChTxPwr) [ChcNum] [ModemPathNum] DB (S3).

The transmission to the next higher processor is the transmission power (TxPwr) which is the DB made for each path because the transmission power values received from each channel card 11a, 11b, 11m must be collected for each path. ModemPathNum] values are accumulated (S4).

The modem path number (ModemPathNum) is increased by one (S5).

Next, it is determined whether the modem path number ModemPathNum is 3 or less (S6).

As a result of determination (S6), if the modem path number is 3 or less, the process is performed again from step S3 to perform the collection process of the transmission power value for the next path.

However, if the determination result (S6) modem path number is not 3 or less (that is, if all transmission power values are collected for three paths), all of the collecting points (abbreviated as GP) are known so far. It is judged whether all have been received from the channel cards 11a, 11b, ..., 11m (S7).

Judgment result (S7) If the GP M (see Fig. 5), which is the time point received from all the channel cards 11a, 11b, ..., 11m, is the base station processor (BSP) 70, which is the upper processor, the sector until now. The transmission power message (TxPwrMsg) formatted with the transmission power values accumulated and collected for each time is transmitted and completed (S8).

In the conventional method of collecting power of a three-path channel transmission combiner of a radio frequency and channel control shelf, when a path of RCPA is limited to three paths, the path is used as a sector meaning. The collection method is collected only sector by sector when used as Omni-FA, 3 sectors per shelf, and when the shelf path is used as a multi-FA or omni-sector when the shelf path is a 6-path. Since the modem path itself is used as a sector and also used as a FA, it is impossible to manage FAs and sectors, and thus there is a problem of incompatibility in various FA and sector operations.

An object of the present invention has been made in view of the above-mentioned problems of the prior art, communication that can collect the transmission power data for frequency transmission (FA) and sector for transmission power monitoring transmitted for each path (path) A method of data collection in a system.

According to an aspect of the present invention for achieving the above object, a multi-processor assembly (MCPA) consisting of a plurality of channel cards having a modem capable of supporting multipath, a radio frequency consisting of a multipath channel transmission combiner and In a base station apparatus having a channel processor assembly (RCPA), a channel card number and a path-specific database are provided in the transmission power message (TxPwrMsg) transmitted from the channel card (CHC). A first step of sequentially setting a modem path number (ModemPathNum), which is a database index for collecting the transmission power message, and a frequency allocation (FA) number for each channel card and modem path; And extracting a lookup index according to the sector identifier ID and performing loop update and collection, and the channel car. A third step of storing a Tx Power value in a message received from the channel in a channel TxPwr [ChcNum] [ModemPathNum] database, and the frequency allocation (FA) and sector-specific database management and transmission power values A fourth step of collecting a value for a TxPwr [faNum] [sectorId] database, and assigning a frequency of the transmit power message TxPwrMsg formatted with the collected transmit power value to the base station processor (BSP). And a fifth step of transmitting each FA).

Hereinafter, a configuration and an operation according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

3 is a hardware configuration diagram of a six-path channel transmission combiner and a transmission path of a radio frequency and channel control shelf of a base station according to the present invention.

The configuration of the six-path channel transmission combiner of the radio frequency and channel control shelf of the base station and the transmission path thereof according to the present invention includes a base station processor of a plurality of assemblies constituting a base transceiver system device of a mobile communication system. Under the control of a base station processor (BSP), a channel card configured in a multi-channel processor assembly (MCPA) 40, which functions as a digital signal processing function of a code division multiple access (CDMA) system, is set from zero to zero (N-1). The first channel card portion 41A having the configuration of " / 2 " channel cards 41a, 41b ... 41n / 2, and the < RTI ID = 0.0 > N / 2 < / RTI > RCPA (Radio-Frequency & Channel Control), which is composed of a second channel card portion 41B having a configuration of 41n-1, and controls radio frequency and channel of a digital signal transmitted from the MCPA 40. A first triple path in which the Processor Assembly (50) is comprised of zero to second path channel transmit combiner ports 51a, 51b, 51c. The channel transmission combiner 52A and the second triple path channel transmission combiner 52B constituted by the third to fifth path channel transmission combiner ports 51d, 51e, and 51f. Here, the first and second triple path channel transmission combiners 52A and 52B indicate FA, and the 0 to fifth path channel transmission combiner ports 51a, 51b, 51c, 51d, 51e, and 51f. Represents a sector.

In addition, the base station sector conversion & up / down convertor assembly (BUDA) 60 for converting the frequency of the signal transmitted from the RCPA 40 is also transmitted from the first triple path channel transmission combiner 52A. The first BUDA (61A) consisting of the 0 to the second BUDA (61a, 61b, 61c) for converting the second and the third to convert the signal transmitted from the second triple path channel transmission combiner (52B) It consists of a second BUDA 61B composed of fifth BUDAs 61d, 61e, 61f.

The 0 th through N th channel cards 41a, 41b... 41n each include a triple path modem chip and a triple path modem chip in a shelf composed of a six path channel transmission combiner 51. When using the manufactured multi-channel card, the first channel card section 41A transmits the 0 to second transmissions of the first triple path channel transmission combiner 51A of the six path channel transmission combiner 51. The transmission path is established by assigning to the ports P0 to P2, and the second half of the second channel card portion 41B is the third to fifth transmission ports P3 of the second triple path channel transmission combiner 51B. Is allocated to P5).

All combiner bits (bit 0 through bit N-1) of the channel transmit combiner register port corresponding to the assigned path for each channel card should be enabled only for the assigned channel card. For example, in order to open the output data transmission path of the (N-1) / 2 channel card 41n / 2, the (N) of the 0th to 2nd ports (P0 to P2) of the transmission combiners in the RCPA 50 are shown. -1) / 2 bits must be enabled high, and in order to open the output data transmission path of the N-1th channel card 41n, the third to fifth ports (P3 to P3) of the transmit combiner in the RCPA 50 must be enabled. The N-1 bit of P5) must be enabled high. At this time, the output data of the (N-1) / 2 channel card 41n / 2 is transmitted from the 0 to the second BUDAs 61a, 61b, 61c through the transmission combiner of the RCPA 50, and the N− Output data of one channel card 41n is transmitted to third to fifth BUDAs 61d, 61e, and 61f.

In case of supporting up to 6 paths, it can be used not only in Omni-FA and 3 sectors but also in 2-FA and 3 sectors, and it can be flexibly operated in various ways even in the structure of 6-FA and Omni sectors. have.

Data or DB management in the shelf structure that can be used in various structures should be able to manage the modem path not only as a sector but also as a FA.

[Table 1] shows the FA for the channel card position and the modem path, which shows whether the modem path is assigned to the FA or the sector according to various operating methods when the number of channel cards M = 6 in FIG. Show sector conversion mapping.

Where N is Not Used.

Here, A-Type is operated as 6-FA Omni-Sector per Shelf. Three FAs are assigned to the first channel card part 41A and three FAs are assigned to the second channel card part 41B. Each modem path in each of the channel card sections 41A and 41B is allocated to one FA each different from the first path and the second path.

B-Type is operated by 2-FA Omni-Sector per shelf. Here, a different FA is assigned to the first channel card portion 41A and the second channel card portion 41B, and the modem paths in the channel card portions 41A and 41B are the first of the first and second paths. Only one FA is assigned to the other FAs.

C-Type is operated by 4-FA Omni-Sector per shelf. Here, two FAs are allocated to the first channel card section 41A and the second channel card section 41B, respectively, and two modem paths in the channel card sections 41A and 41B are provided for the first path and the second path. The FA is assigned.

D-Type is operated with Omni-FA 3-Sector per shelf. Here, one FA is assigned only to the first channel card section 41A, and the modem path is assigned to three sectors in the first path.

E-Type is operated with 2-FA 3-Sector per shelf. Here, one FA is allocated to the first channel card portion 41A and the second channel card portion 41B, and three sectors are allocated to the first path and the second path, respectively.

As shown in Table 1, depending on how the FA and the Sector operate, the modem path may be assigned to the FA or may be used as the Sector.

Here, the message content transmitted to the upper processor (BSP) 70 for transmission power (Tx Power) monitoring should be content collected by each FA and sector.

First, upon reception of a transmit power message (TxPwrMsg) from the i-th channel card (S11), the corresponding channel card number i is substituted into the channel number (ChcNum) (ChcNum = i), and the contents of the message for each path of the modem. Are sequentially updated in a database for each channel card and path. Subsequently, the modem path number ModemPathNum, which is the DB index, is initialized and set to 0 (ModemPathNum = 0) (S12).

Then, as one of the proposed methods for compatibility in various operating modes, the LUP is extracted to perform limited loop update and collection in order not to update the area indicated by N (Not Used) in Table 1. . Here, the lookup index is an index for representing a usable area excluding Not Used. If the acquisition is performed unconditionally up to 3, the number of modem paths without extracting the lookup index, the collection is performed by converting the modem path number to the FA number and sector number according to the operation type. This is because the value is accumulated as the final value and the collection is performed with the wrong transmission power value (S13). And unlike DB, memory for storing lookup index is configured.

Subsequently, the transmit power value (Tx Power) in the message received from the i-th channel card is stored in the channel transmit power (ChTxPwr) [ChcNum] [ModemPathNum] DB (S14).

Next, the FA # (faNum) and sector # (sectorId) mapped in Table 1 are extracted using the channel card number (ChcNum) and the modem path number (ModemPathNum), which are the channel card numbers currently collected (S15). . This is a proposed method for managing and collecting by FA and sector in various operating modes.

By using the extracted FA # (faNum) and sector ID (sectorId), the values of FA management and DB management and transmission power values are accumulated in the transmission power TxPwr [faNum] [sectorId] DB (S16). ).

Next, the modem path number (ModemPathNum) is incremented by one to process the modem path (S17).

Subsequently, it is determined whether the modem path number ModemPathNum is smaller than the LookUpIndex (S18).

If it is determined in step S18 that the modem path number ModemPathNum is smaller than the LookUpIndex, the process returns to step S14 to perform a process of collecting transmit power values for the next path.

However, if the determination result (S18) modem path number (ModemPathNum) is not smaller than the LookUpIndex, all of the transmission power value collection processing for the desired path is performed. It is determined whether it has been received from (S19).

As a result of the determination, if the collecting point M (Gathering Point: GP) (refer to FIG. 5), which is the point of time received from all the channel cards (CHC), is used as the transmission power value accumulated by each modem path to the base station processor (BSP), which is a higher processor, The transmitted transmission power message (TxPwrMsg) is transmitted for each FA and completed (S20).

For reference, FIG. 5 is a diagram for describing a method for transmitting and receiving a message between a base station processor and a channel card in a general base station, wherein 70 is a base station processor 70 generating a transmit power request message to the RCPA 80, and 90 is a plurality of base stations. As described above, when the MCPA of the base station processor 70 generates the transmit power request message, the RCPA 80 collects the transmit power request message as described above and transmits the transmit power request message through the transmit power message. 70) to BUDA.

As described above, the present invention transmits in a variety of operating modes ranging from variable multi-FA, Omni-Sector to Omni-Sector, multi-Sector in a shelf where a band-end transmission path in a base station supports a six-path. As db management or collection for power monitoring can be maintained by FA and Sector, it is possible to flexibly collect and manage.
