Abstract
The invention discloses a response method which aims at the tower top amplifier gain operation, comprising that the response message format of the operation is unified when the tower top amplifier is in the bypass mode, and the bypass mode of the tower top amplifier is reflected in the response message. The invention leads the user to be aware of the real TMA gain accurately at any time, unifies the equipment TMA control interfaces provided by all the equipment suppliers and improves the equipment maintainability.
Description
Technical field
The present invention relates to the response message technology in the wireless communication system, particularly at the response method of tower amplifier gain operation.
Background technology
Tower amplifier (TMA) is parts in the 3G system, when antenna and NodeB base station distance are far away, connects antenna and NodeB base station with TMA, is used to regulate because the long signal gain that causes of radio frequency feeder is lost, and connected mode as shown in Figure 1.
At present, the agreement that is applied to TMA mainly comprises two kinds, a kind of is the agreement that antennal interface standards groups (AISG) is formulated with reference to the open system interconnection (osi) model, and another kind is the electrically adjustable antenna interface agreement that 3GPP formulates, and its protocol architecture respectively as shown in Figures 2 and 3.In these two kinds of agreements, the gain of TMA can be regulated, and makes to take place can change TMA under the prerequisite of fixedization in radio frequency feeder length, and directly adopts the mode of interface command to carry out the adjusting that TMA gains.Defined the TMA pattern that is provided with, inquiry TMA pattern in the agreement, the TMA gain be set and inquire about the interface that TMA gains, it describes as shown in table 1:
| Order | Command code |
| The TMA pattern is set | 0x40 |
| Inquiry TMA pattern | 0x41 |
| The TMA gain is set | 0x42 |
| Inquiry TMA gain | 0x43 |
Table 1
Wherein, the user can also can inquire about the current yield value of TMA by inquiry TMA gain command by the yield value that the TMA gain command is provided with TMA is set.
But, because TMA has normal mode and two kinds of mode of operations of bypass mode, under normal mode, the return value of carrying out inquiry TMA gain command is the current gain value of TMA, and under bypass mode, the return value of carrying out inquiry TMA gain command on distinct device supplier's equipment may be that the user is the yield value that TMA pre-sets, also may be current actual gain value 0, in the middle of the agreement this is not clearly stipulated, this has just caused the return value disunity, and the user might can't be known the current gain value of TMA.
