Third embodiment:

The present invention will be further explained in conjunction with specific application scenarios.

In the UMTS system, if the RTWP value in the cell broadcast is abnormal, the UE accesses the cell with relatively high power, resulting in a decrease in system capacity, which seriously affects system stability. By modifying the RTWP before the broadcast, the present invention can effectively counteract the rise of the value and solve the problem. Preferably, the NodeB processes the RTWP reported by the baseband according to the algorithm indicating factor set by the network management UMTS reservation parameter (that is, the modification rule in the foregoing embodiment), and writes the calculated new RTWP value into the SIB7 according to the corresponding algorithm. UL-interference position, using subsequent The cell broadcasts to the UE. There are three kinds of algorithm indication factors for UMTS reserved parameters: the default value is the actual RTWP value; the relative value is converted according to the given formula to the current RTWP value; the absolute value directly configures the RTWP value as the target value.

Preferably, the RTWP value control method provided in this embodiment includes:

Step 1: Configure an algorithm indicator of the RTWP in the UMTS reservation parameter of the network management tool, and synchronize the configuration to the NodeB.

Step 2: After the cell is established, the measurement module periodically collects the RTWP value reported by the DSP (digital signal processor), and reports the value to the cell module.

Step 3: The cell records the RTWP value into the instance area, and starts the sib7 process;

Step 4: In the sib7 process, modify the value of the UL interference IE in the sib according to the algorithm indicator factor configured by the network management tool. If the configuration is 0, the default value is used, which is the same as when the function is not enabled. If the configuration is 1, the relative configuration is used, and the current RTWP is corrected according to rtwp_sib7=-106+(rtwp_current+106)*0.5dBm, where rtwp_current For the value reported by the current measurement module, rtwp_sib7 is the corrected value; if configured to be between [70, 110], rtwp_sib7=0-configuration value; if configured to any other value, it is an illegal value, the system performance and default value Same time.

Step 5: The sib7 process writes the corrected RTWP value to the broadcast buffer, waiting for the DSP to broadcast it on the next broadcast.

S304: The baseband resource processing subsystem is stored in the broadcast buffer.

S305: In the next broadcast, the DSP broadcasts the RTWP value.

Scene two

As shown in FIG. 4, the RTWP value control method provided by the present invention includes:

S401: The DSP module reports the RTWP value to the baseband resource processing subsystem.

S402-S408: The baseband resource processing subsystem starts the sib7 process and executes the set algorithm. The algorithm may be one of the following three types:

a) default value, set the RTWP in SIB7 to the current actual value;

b) relative value, set the RTWP in SIB7 to -106+ (current value +106)*0.5;

c) Absolute value, set the RTWP in SIB7 to the configured value.

S409: The baseband resource processing subsystem fills in the RTWP value into the sib7 of the system information update, stores it in the broadcast buffer, and waits for the DSP to broadcast the RTWP value in the next broadcast.

The invention processes the cell broadcast according to the corresponding algorithm in the case that the environment of the base station changes drastically, the channel quality jumps rapidly, and the receiving broadband noise is abnormally increased, so that the RTWP value in the broadcast received by the UE is not Abnormal hopping and rapid rise occur, which solves the problem that the UE directly uses relatively large power access to cause system instability when the channel quality is poor.
