S1, user terminal obtain CSG cell deployment scene;
S2, user terminal select to obtain the method for measuring the space according to the said CSG cell deployment scene of obtaining.
In the present embodiment, as shown in Figure 5, step S1 comprises step:
S1A, user terminal receive the signal of CSG sub-district and the signal of macrocell in moving process.
S1B, user terminal are confirmed CSG cell deployment scene according to said CSG cell signal and macrocell quality of signals.
The CSG cell signal quality that receives when user terminal is more than or equal to the strong signal threshold value in CSG sub-district (CSG_Thresholdhigh); And the macrocell signal quality is during more than or equal to the strong signal threshold value of macrocell (MACRO_Thresholdhigh), then confirm CSG cell deployment scene be the CSG sub-district with macrocell with covering;
The CSG cell signal quality that receives when user terminal during less than macrocell weak signal threshold value (MACRO_Thresholdlow), confirms then that CSG cell deployment scene is CSG sub-district and macrocell expansion covering more than or equal to the strong signal threshold value in CSG sub-district and macrocell signal quality;
The CSG cell signal quality that receives when user terminal during less than macrocell weak signal threshold value, confirms then that CSG cell deployment scene is that covering is extended with macrocell in the CSG sub-district less than CSG sub-district weak signal threshold value (CSG_Thresholdlow) and macrocell signal quality.
Wherein, Be used to judge the strong signal threshold value in CSG sub-district, CSG sub-district weak signal threshold value, the strong signal threshold value of macrocell, the macrocell weak signal threshold value of CSG cell deployment scene; Can be by core net setting (specifically being provided with can be that operator passes through the setting of core net webmaster) and through NAS (Non Access Stratum; Non-Access Stratum) signaling sends to UE; Perhaps be provided with on the HeNB through dedicated signaling RRC (RadioResource Control, Radio Resource control) and be handed down to UE, also can be the default value of agreement regulation.
