Step 101: the base station of second network receives the information sent by the base station of first network or base station controller BSC, the information of resource is reserved in the base station that described information comprises first network;

Step 102: the base station of second network sends particular sequence in described reserved resource, to detect the signal quality of the described particular sequence obtained according to terminal, determine whether the test point residing for described terminal is in the coverage of described second network.

Alternatively, when the base station of second network receives the information sent by base station controller BSC, when the information of resource is reserved in the base station that described information comprises first network, described information should first be sent to described BSC by the base station of described first network, after described BSC receives described information, just send to the base station of second network.In real network environment, described BSC is responsible for coordinating the Resourse Distribute between base station, coordinates the use of resource between base station.

As shown in Figure 2, in embodiments of the present invention, suppose that the base station of second network receives the information sent by described BSC.Described BSC can notify that a part of resource is reserved in the base station of first network, and the information of this idling-resource is sent to described BSC, and then the information of described idling-resource is sent to the base station of second network by described BSC.The type of described reserved resource is different according to the standard difference of network, and a part of resource also can be reserved according to the instruction of described BSC in the base station of first network, then reserved resource is sent to described BSC.The base station of second network is according to the notice of described BSC, the particular sequence for test network coverage condition that the base station that described reserved resource sends second network generates, the particular sequence that the base station of second network sends is different according to the standard difference of network, as long as can be received by terminal and can measure corresponding signal intensity according to these particular sequences.After these particular sequences are received by terminal, can be detected by terminal, terminal measures received signal strength indicator RSSI (the Received Signal Strength Indication of particular sequence, received signal strength indicator), carrier interference ratio C/I NR (Carrier to Interference and Noise Ratio, carrier/interface ratio) or signal to noise ratio snr (Signal to Noise Ratio, signal to noise ratio), terminal just can analyze the network coverage situation of second network according to RSSI, CINR or SNR of testing out.But it should be noted that, terminal depends on the type of network according to one or more in RSSI, CINR or SNR and different, such as, for GSM network, then need the signal quality more accurately being determined described particular sequence by RSSI and SNR two ability, only can not reflect the signal quality situation of described particular sequence according in RSSI, CINR or SNR completely.
