As stated in the Background Art, under with frequency heterogeneous network deployment scenario (for example Macro and Pico, Macro and femto dispose), owing to introduced the time domain interference coordination technology, may there be larger difference in the radio link quality on the different time-domain resource.And traditional terminal equipment side Radio Link monitoring and RRM to measure very little with the fluctuation of the radio link quality on the different time domain resource serve as to suppose prerequisite.When heterogeneous network disturbs when very strong, this supposition is no longer set up, and the radio link quality difference that need allow terminal equipment know may to exist is to guarantee Radio Link monitoring and the RRM measuring reliability of terminal equipment.
Based on this, the embodiment of the invention has proposed a kind of Notification Method of measuring restricted information, realize measuring the notice of restricted information and the adjustment of the measurement restriction strategy when terminal equipment carries out the residential quarter switching, guarantee Radio Link monitoring and the RRM measuring reliability of terminal equipment.
As shown in Figure 3, be a kind of schematic flow sheet of measuring the Notification Method of restricted information that the embodiment of the invention proposes, this method specifically may further comprise the steps:
Step S301, when receiving the measurement that the current terminal equipment of serving in first residential quarter sends, the base station of first residential quarter reports, when determining that terminal equipment need move into second residential quarter from first residential quarter, the base station of first residential quarter sends the handover request message of terminal equipment to the base station of second residential quarter.
The base station of step S302, first residential quarter receives the switch indicating information of measuring restriction strategy adjustment indication that comprises that the base station of second residential quarter sends.
The base station of step S303, first residential quarter is according to measuring restriction strategy adjustment indication, and the notice terminal equipment is measured second residential quarter and co-frequency neighbor cell according to the corresponding restricted information of measuring.
Wherein, first residential quarter is macrocellular Macro residential quarter, and second residential quarter is Pico cell Pico residential quarter, or first residential quarter is the Pico residential quarter, and second residential quarter is the Macro residential quarter.
Below in conjunction with concrete cell type, above-mentioned step is carried out specific description, at first, before step S301, comprise that also the process of restricted information configuration is measured for the terminal equipment of local service in the base station of first residential quarter, that is:
Current terminal equipment of serving sends measurement restriction strategy notification message to first residential quarter in the base station of first residential quarter, so that terminal equipment is measured first residential quarter and co-frequency neighbor cell according to measuring the corresponding measurement restricted information of restriction strategy.
According to the difference of cell type, above-mentioned processing procedure comprises:
When first residential quarter is the Macro residential quarter, when second residential quarter is the Pico residential quarter, current terminal equipment of serving sends the measurement restriction strategy notification message that carries the measurement restricted information to the Macro residential quarter in the base station of Macro residential quarter, so that terminal equipment is according to measuring restriction strategy, use to measure restricted information all adjacent residential quarters are measured, the measurement of Macro residential quarter then is not restricted.
When first residential quarter is the Pico residential quarter, when second residential quarter is the Macro residential quarter, current terminal equipment of serving sends the measurement restriction strategy notification message that carries the measurement restricted information to the Pico residential quarter in the base station of Pico residential quarter, so that terminal equipment is according to measuring restriction strategy, use to measure restricted information the Pico residential quarter is measured, the measurement of co-frequency neighbor cell then is not restricted.
Wherein, in concrete application scenarios, carry the measurement restriction strategy notification message of measuring restricted information in two kinds of above-mentioned situations, be specially in the mode of Bitmap and carry the RRC dedicated signaling of measuring restricted information.
Further, measure restricted information and specifically comprise following two types:
The ABS subframe of type one, Macro residential quarter.
The measurement restriction subframe that the base station of type two, first residential quarter is determined according to preset algorithm.
In actual applications, specifically adopt which kind of above-mentioned type to adjust according to actual needs, such variation does not influence protection scope of the present invention.
According to the type difference of the measurement restricted information of using, corresponding processing procedure also is divided into following two kinds of situations:
Situation one, measurement restricted information are specially the base station measurement restriction subframe definite according to preset algorithm of first residential quarter.
At first, measure for the terminal equipment of local service in the process of restricted information configuration in the base station of first residential quarter, the base station of first residential quarter need be determined the measurement restriction subframe of self according to preset algorithm, and notifies corresponding terminal equipment.
In step S301, when terminal equipment moves into second residential quarter by first residential quarter, the base station measurement restriction subframe definite according to preset algorithm of first residential quarter carried in the base station of first residential quarter in the handover request message in the process of the handover request message of the base station transmission terminal equipment of second residential quarter.
After handover request message sends, for the base station of second residential quarter, also comprise following processing procedure:
The measurement restriction subframe of self is determined in the base station of second residential quarter according to the preset algorithm of self;
Whether the measurement restriction subframe that self is judged in the base station of second residential quarter is identical with entrained measurement restriction subframe in the handover request message that the base station of first residential quarter sends.
Then, in step S302, the difference of the judged result of judging according to the base station of second residential quarter, the switch indicating information of measuring restriction strategy adjustment indication that comprises that the base station of second residential quarter that the base station of first residential quarter is received sends specifically comprises following two kinds of situations:
