[59] in order that those skilled in the art more fully understand the technical scheme in the embodiment of the present invention, and enable the above-mentioned purpose of the embodiment of the present invention, feature and advantage more obvious understandable, technical scheme in the embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
[60] it is the method flow diagram that frequency is transmitted in a kind of acquisition base station of the embodiment of the present invention referring to figure la.[61] in the embodiment of the present invention, as shown in figure lb, first base station is placed on by cloth in the overlay area of the second base station, and terminal services or resided in the second base station by the second base station.Wherein, first base station is micro- station, and the second base station is macro station, or first base station is macro station, and the second base station is micro- station, and other situations are there is likely to be certainly, first base station and the second base station are not specifically limited herein.The transmission frequency of second base station is different from the transmission frequency of first base station；Transmission frequency is the wireless frequency for carrying Zone information.The method of the acquisition first base station frequency can include：
[62] step 101, terminal receives first base station and the wireless signal sent on frequency is transmitted in the second base station.
[63] the transmission frequency point information of first base station can be directly included in the wireless signal that the terminal is received；If not including the transmission frequency point information of first base station in wireless signal, the corresponding relation between transmission frequency and the characteristic information of wireless signal can be preset（Hereinafter referred to as corresponding relation）, wherein, characteristic information is the information for identifying wireless signal, such as the numbering that can be unique mark wireless signal.The corresponding relation can be one transmission frequency of characteristic information correspondence of a wireless signal（Can abbreviation frequency）, or one group of wireless signal one transmission frequency of characteristic information correspondence, or one group of wireless signal characteristic information one group of transmission frequency of correspondence.So that wireless signal is DS signals as an example, the corresponding relation can be：
[64] { (DSO, frequency 0);(DS1, frequency 1);(DS2, frequency 2);(DS3, frequency 3) };
[65] or { ((DS0, DS1, DS2), frequency 0);((DS3, DS4, DS5), frequency 1)；((DS6, DS7, DS8), frequency 2);((DS9, DS10, DS11), frequency 3) }；
[66] or { ((DS0, DS1, DS2), (frequency 0, frequency 1));((DS3, DS4, DS5),（Frequency 1, frequency 2));((DS6, DS7, DS8), (frequency 2, frequency 3));((DS9, DS10, DS11), (frequency 3, frequency 4》}.Wherein, DSn is the characteristic information or mark of a certain DS signals, n=0,1,2 ....
[67] first base station can know the corresponding relation first, be then based on the corresponding relation and the transmission frequency of its own before wireless signal is sent, it is determined that the wireless signal to be sent, for example, corresponding relation is DS0, frequency 0)；(DS1, frequency 1);(DS2, frequency 2);(DS3, frequency 3) }, first base station transmission frequency is frequency 2, then can determine that the first base station wireless signal to be sent is DS2.Wherein, first base station knows that the mode of the corresponding relation can be the corresponding relation that is stored with advance in first base station, can also prestore the corresponding relation in the second base station or other management nodes, it is then by the second base station or management node that the corresponding relation is interim（When first base station will send wireless signal）Or first base station is sent in advance.
[68] first base station is before wireless signal is sent, it can also need not know above-mentioned corresponding relation, but by the second base station or management node according to the above-mentioned corresponding relation prestored and the transmission frequency for the first base station known in advance, determine the characteristic information of the corresponding wireless signal of transmission frequency of the first base station, then the characteristic information of the wireless signal is informed into first base station, for example, DS2 is informed into first base station.
[69] first base station is after the wireless signal to be sent is determined, the wireless signal can be sent on the transmission frequency of the second base station, so that the terminal for servicing or residing in the second base station by the second base station can receive the wireless signal of first base station transmission on the transmission frequency of the second base station.
[70] step 102, terminal knows the transmission frequency of first base station according to the wireless signal received.
[71] terminal further determines that the transmission frequency of first base station after the wireless signal of first base station transmission is received according to the wireless signal, wherein, terminal knows that the mode of first base station transmission frequency has a variety of, for example, if directly containing the transmission frequency point information of the first base station in the wireless signal that terminal is received, such as 2100MHz or the 1st frequency, terminal can directly determine the transmission frequency of first base station according to the information included in the wireless signal；If not including the transmission frequency point information of first base station in wireless signal, then terminal can be voluntarily according to the wireless signal received, and the corresponding relation between transmission frequency and the characteristic information of wireless signal determines the transmission frequency of first base station, can also receive the transmission frequency of the first base station determined based on the corresponding relation of other nodes such as transmission such as second base station.The terminal knows that the detailed process of first base station transmission frequency refers to the detailed description of subsequent embodiment.
[72] terminal is after the transmission frequency of first base station is known, you can directly carried out on the transmission frequency of the first base station
[73] certainly, in another embodiment, terminal can also report the second base station before measuring, receive the second base station transmission allow indicate after perform measurement again, if if not receiving, this allows to indicate or Warning Mark is does not allow during measurement, and terminal is measured not on the transmission frequency of first base station.
[74] in the embodiment of the present invention terminal after the wireless signal of first base station is received, by the transmission frequency point information of the first base station included in the corresponding relation or wireless signal between the transmission frequency and the characteristic information of wireless signal that pre-set, the transmission frequency of first base station when carrying out different-frequency measure can be obtained, so as to directly be measured on the transmission frequency of first base station, without being soundd out on a large amount of possible frequencies, so as to shorten time of measuring, the energy consumption of the terminal caused by repeatedly measurement is reduced.
