To include：
401st, the first intensity value of uplink signal of the relatively described macro stations of UE of macro station and described is currently accessed described in obtaining
It is currently accessed the second intensity value of the uplink signal of the relatively described LPN of UE of macro station；
402nd, second intensity value is subtracted into first intensity value, obtains uplink signal strength difference；
If the 403rd, the uplink signal strength difference is more than default threshold value, in the coverage for judging the LPN
There are the first UE；
If the 404, the uplink signal strength difference is less than or equal to the threshold value, judge in the LPN coverages
There is no the first UE.
Wherein, the threshold value is the maximum transmit power according to the macro station and the maximum transmit power of the LPN
What difference obtained.
It should be noted that whether the UE that the present embodiment is currently accessed macro station again by detection is in covering for the LPN
In the range of lid, detect with the presence or absence of the first UE in the coverage of the LPN, detailed process with the phase in embodiment three inside the Pass
Hold similar, details are not described herein for the present embodiment.
Optionally, in an embodiment of the present embodiment, the executive agent of above-mentioned steps can be RNC, then 401 tool
Body can include：
RNC sends first information inquiry request to the macro station, so that the macro station please according to first information inquiry
Ask the channel information for the UE that macro station is currently accessed described in obtaining and first intensity value；
The RNC receives the first information inquiry response that the macro station returns, and the first information inquiry response includes institute
State the channel information for the UE for being currently accessed macro station and first intensity value；
The RNC sends the second information inquiry of the channel information for the UE that macro station is currently accessed described in carrying to the LPN
Request, to indicate that the LPN is currently accessed channel information acquisition second intensity value of the UE of macro station according to；
The RNC receives the second information inquiry response that the LPN is returned, and second information inquiry response includes described
Second intensity value.
Optionally, in the another embodiment of the present embodiment, the executive agent of above-mentioned steps can also be described
LPN, then the first intensity value for being currently accessed the uplink signal of the relatively described macro stations of UE of macro station described in 401 described in acquisition are specific
It can include：
The LPN sends the 3rd information inquiring request to the macro station, so that the macro station is looked into according to the 3rd information
It askes request and obtains first intensity value；
The LPN receives the 3rd information inquiry response that the macro station returns, and the 3rd information inquiry response includes institute
State the first intensity value.
Wherein, the concrete form of first intensity value and second intensity value can be decibel value.The LPN is obtained
The specific method of first intensity value and second intensity value can pass through the accomplished in many ways in the communications field, this reality
Example is applied no longer to be specifically described herein.
Wherein, the concrete form of the maximum transmit power of the maximum transmit power and LPN of the macro station or
Decibel value, and the maximum transmit power of the macro station and the maximum transmit power of the LPN can respectively according to the macro station and
The running parameter of the LPN determines, for concrete example, if the maximum transmit power of the macro station is 43 decibel milliwatts（Referred to as
dBm）, the maximum transmit power of the LPN is 37dBm, then the threshold value is 6dBm.
Optionally, according to the maximum transmit power of the macro station and the difference of the maximum transmit power of the LPN, institute is obtained
