Below in conjunction with the accompanying drawing among the present invention, the technical scheme among the present invention is clearly and completely described, obviously, described only is a part of the present invention, rather than whole.Based on the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other invention that is obtained under the creative work prerequisite.
District staying method during a kind of starting up of terminal that the embodiment of the invention proposes as shown in Figure 2, may further comprise the steps:
Wherein, before this step was carried out, described terminal need be obtained the first frequency decision threshold; This obtain manner includes but not limited to:
Described terminal is provided with the first frequency decision threshold according to the business demand of self; Or,
Network side is provided with the first frequency decision threshold according to the business demand of terminal, and the described first frequency decision threshold is sent to described terminal.
Further, described terminal is provided with the first frequency decision threshold according to self business demand and comprises: described terminal is according to the CS business setting first frequency decision threshold of self; And/or,
Described terminal is according to the PS business setting first frequency decision threshold of self.
In embodiments of the present invention, described when obtaining at least one alternative frequency that satisfies the second frequency decision threshold, described terminal also needs to preserve the information of the alternative frequency that gets access to, and uses this alternative frequency that gets access to handle accordingly then in subsequent processes.
Concrete, this corresponding processing procedure comprises: (1) attempts carrying out the sub-district when resident at alternative frequency in described terminal, described terminal is selected an alternative frequency from the alternative frequency of preserving, described alternative frequency as resident frequency, and continue to carry out is attempted carrying out the resident operation in sub-district at described resident frequency.And/or when (2) need carry out the sub-district gravity treatment when described terminal, described terminal was selected the preferential frequency of the alternative frequency of an optimum as the sub-district gravity treatment from the alternative frequency of preserving.Certainly, in the embodiment of the invention, the process of carrying out respective handling according to alternative frequency is not limited thereto, and gives unnecessary details no longer in detail in the embodiment of the invention.
In addition, in embodiments of the present invention, described terminal also needs to write down the frequency of self measuring that can not satisfy described first frequency decision threshold and the described second frequency decision threshold according to the storage thresholding; When resident frequency and all resident failure of all alternative frequencies, described terminal attempts carrying out the sub-district on the frequency that can not satisfy described first frequency decision threshold and the described second frequency decision threshold resident.Certainly, according to the actual needs, in the resident process of resident frequency and alternative frequency (not all resident failures), also can select frequency (promptly can not satisfy the frequency of described first frequency decision threshold and the described second frequency decision threshold) the trial sub-district of this record resident, not repeat them here.
Need to prove, in said process, can use 3 threshold values, be the above-mentioned first frequency decision threshold, the second frequency decision threshold and storage thresholding, wherein, this first frequency decision threshold is used to obtain resident frequency, this second frequency decision threshold is used to obtain alternative frequency, this storage thresholding need be lower than the first frequency decision threshold and the second frequency decision threshold, guaranteeing when resident frequency and all resident failure of all alternative frequencies, it is resident to make terminal have lower frequency to attempt carrying out the sub-district.
Concrete, the first above-mentioned frequency decision threshold be terminal according to the business demand of self set (or network side is set according to the business demand of terminal), describe in the superincumbent step, repeat no more.The second above-mentioned frequency decision threshold can be provided with according to actual needs, promptly this second frequency decision gate can be provided with greater than this first frequency decision threshold, the quality of the feasible alternative frequency that gets access to is better than resident frequency, in subsequent process, can use this better alternative frequency to carry out operations such as sub-district gravity treatment; In addition, this second frequency decision gate can also be provided with less than this first frequency decision threshold, the quality of the feasible alternative frequency that gets access to is lower than resident frequency, in subsequent process, can use this lower alternative frequency to attempt that sub-district is resident waits operation, be about to this lower alternative frequency as resident frequency, it is resident to attempt the sub-district then, certainly, also can use this lower alternative frequency to carry out operations such as sub-district gravity treatment.
Further,, can also make the second frequency decision threshold identical, at this moment, only need 2 threshold values to get final product, first promptly above-mentioned frequency decision threshold and storage thresholding with the first frequency decision threshold in order to simplify the threshold value quantity in the embodiment of the invention.In this case, terminal can use this first frequency decision threshold to obtain resident frequency and alternative frequency, and promptly in the step 201, terminal can be obtained at least one alternative frequency according to the first frequency decision threshold, does not repeat them here.
As seen, in the method provided by the present invention, can effectively shorten the time delay of starting up of terminal frequency sweep, make terminal can initiate business as soon as possible, improve user's use experience, in addition, terminal is when a certain frequency trial sub-district is resident, satisfying the frequency of frequency decision threshold by continue seeking next, having reduced because of resident failure and having searched for the employed time delay of frequency again; If certain frequency persistent district success can also be satisfied other the alternative frequency of frequency of frequency decision threshold as this terminal sub-district gravity treatment, accelerated the process of sub-district gravity treatment.
As shown in Figure 3, for in the embodiment of the invention in conjunction with a kind of concrete application scenarios, the detailed description that district staying method during to starting up of terminal carries out, should be with under the scene, the resident process in sub-district with when start in the TD-SCDMA network is that example describes, and wherein, the application scenarios that the embodiment of the invention was suitable for is not limited to the TD-SCDMA network, for the resident process in the sub-district in other networks, repeat no more in the embodiment of the invention.
In the embodiment of the invention, need store the frequency decision threshold in advance on terminal, wherein, the acquisition methods of this frequency decision threshold includes but not limited to: terminal is provided with the frequency decision threshold according to the business demand of self; Network side is provided with the frequency decision threshold according to the business demand of terminal, and this is provided with the terminal that the frequency decision threshold sends to correspondence.It is identical with the mode that network side is provided with the frequency decision threshold that this terminal is provided with the frequency decision threshold, and with terminal the frequency decision threshold being set among the present invention is that example describes.
Concrete, terminal is provided with the frequency decision threshold according to self business demand and includes but not limited to: (1) terminal is according to CS (Circuit switching, circuit switching) the business setting frequency decision threshold of self; Wherein, in order to guarantee carrying out smoothly of self CS business, this terminal can be according to the use frequency point setting frequency decision threshold of CS business; For example, when carrying out frequency that the CS service needed uses for-80dbm, this terminal can the frequency decision threshold be set to-90dbm (as long as the frequency that uses less than the CS service needed).(2) terminal is according to PS (Packet Switching, packet switching) the business setting frequency decision threshold of self; Similar with the setting up procedure of (1), this terminal can be according to the use frequency point setting frequency decision threshold of PS business; For example, when carrying out frequency that the PS service needed uses for-70dbm, this terminal can be set to-80dbm by the frequency decision threshold.Certainly, be not limited in the embodiment of the invention according to CS business and/or PS business setting frequency decision threshold, can also be according to other business setting frequency decision threshold, or a frequency decision threshold is set arbitrarily according to the actual needs.Give unnecessary details no longer in detail in the embodiment of the invention.In addition, after the setting of frequency decision threshold was finished, this terminal need be stored this frequency decision threshold, and the resident process in sub-district when using this frequency decision threshold to carry out follow-up starting up of terminal.
Concrete, the district staying method during above-mentioned starting up of terminal may further comprise the steps:
Step 301 is directly searched for frequency behind the starting up of terminal.Wherein, can use best frequency in order to guarantee terminal, this terminal can be searched for the highest frequency sub-band of frequency range earlier.For example, for existing 1880-1900MHz frequency sub-band, 1900-1920MHz frequency sub-band and 2010-2025MHz frequency sub-band, this terminal is searched for from the 2010-2025MHz frequency sub-band earlier; Certainly, according to the actual needs, this terminal also can begin search from other frequency sub-band.
Whether the frequency that step 302, terminal judges search satisfies the frequency decision threshold; When the frequency that searches satisfies the frequency decision threshold, forward step 304 to, otherwise, forward step 303 to.Wherein, in terminal, stored the frequency decision threshold, when searching frequency, can directly this frequency and frequency decision threshold have been compared.For example, when the frequency decision threshold be-during 75dbm,, find that the performance number of frequency A is-70dbm that then frequency A satisfies the frequency decision threshold, forwards step 304 to if during the starting up of terminal frequency sweep; And if the performance number of frequency A is-80dbm, then frequency A does not satisfy the frequency decision threshold, forwards step 303 to.
It is resident that step 303, terminal determine to carry out the sub-district at this frequency.Wherein, according to the actual needs, this terminal (for example can write down the frequency point information that can not satisfy the frequency decision threshold measured, the performance number of this frequency etc.), all can not carry out the sub-district at all frequencies when resident, it is resident to select optimum frequency to attempt the sub-district from the frequency point information that can not satisfy the frequency decision threshold that write down.Certainly, this terminal also can not write down the frequency point information of measuring that can not satisfy the frequency decision threshold, does not repeat them here.
Need to prove, determining to carry out the sub-district at this frequency in this step, resident just can not to carry out the sub-district at this frequency in initial frequency sweep resident, and all can not carry out the sub-district when resident when all frequencies, it is resident also may to select this frequency to carry out the sub-district, for example, when this frequency was frequency optimum in the frequency point information that can not satisfy the frequency decision threshold measured of terminal, it was resident also can to attempt carrying out the sub-district at this frequency.
In the embodiment of the invention, a storage thresholding can also be set, thereby guarantee the quantity of the frequency point information that can not satisfy the frequency decision threshold of record, in limited scope, to improve the treatment effeciency of terminal.Promptly have only when frequency satisfies this storage thresholding (greater than the storage thresholding), terminal just can write down this frequency point information (can not satisfy the frequency point information of frequency decision threshold), has effectively reduced the data that terminal need write down.
Further, the setting up procedure of this storage thresholding and the setting up procedure of frequency decision threshold are similar, also can be provided with according to service needed by terminal or network side, just when being set, this storage thresholding also needs to consider the frequency decision threshold, promptly should store thresholding should be less than the frequency decision threshold, for example, the frequency decision threshold is-during 75dbm, can be-90dbm with the storage threshold setting.In addition, can also directly the storage thresholding be set, get final product less than the frequency decision threshold, not repeat them here to guarantee the storage thresholding according to the frequency decision threshold.
It is resident that step 304, terminal determine to carry out the sub-district at this frequency, and it is resident to attempt carrying out the sub-district at this frequency.Wherein, satisfying the frequency decision threshold with the performance number of finding frequency A in the step 302 in the embodiment of the invention is that example describes, and promptly to attempt carrying out the sub-district at frequency A resident for this terminal.
In the embodiment of the invention, when carrying out the resident trial in sub-district at frequency A, this terminal will continue the residue frequency is carried out frequency sweep, obtain the frequency B that next satisfies the frequency decision threshold, and the frequency point information of storage frequency B; Continue to carry out the process of the residue frequency being carried out frequency sweep, obtain the frequency C that next satisfies the frequency decision threshold, and the frequency point information of storage frequency C, and the like, until attempting the resident process in sub-district at frequency A, terminal finishes.
Need to prove, this step is carried out frequency sweep in execution to the residue frequency, when obtaining next frequency B that satisfies the frequency decision threshold and subsequent operation, the frequency decision threshold that uses can be identical with the frequency decision threshold (being employed frequency decision threshold in the step 302) of above-mentioned use, thereby obtain the frequency that next satisfies the frequency decision threshold; Also can reset a frequency decision threshold according to actual needs, make terminal to obtain the frequency that next satisfies the frequency decision threshold according to this new frequency decision threshold, this new frequency decision threshold can be greater than employed frequency decision threshold in the step 302, also can be less than employed frequency decision threshold in the step 302, in the embodiment of the invention, for convenience of description, when obtaining next frequency that satisfies the frequency decision threshold and subsequent operation, the frequency decision threshold of use is all example mutually with the frequency decision threshold of above-mentioned use and describes.
Whether step 305, terminal judges in the resident success in frequency A sub-district, resident when successful when the sub-district, forwards step 306 to, otherwise, forward step 307 to.
Need to prove, when the performance number of frequency A satisfies the frequency decision threshold, can only illustrate that this frequency A satisfies the resident preliminary ruling thresholding in sub-district, can not guarantee that this terminal can be in the resident success in frequency A sub-district, this frequency A also needs to satisfy other resident resident parameters of sub-district, for example, the terminal received power needs greater than the minimum received power in sub-district etc., for the judging process of other resident parameters, be not the content that will consider in the embodiment of the invention, give unnecessary details no longer in detail among the present invention.
Concrete, when resident when successful in frequency A sub-district, terminal also can be carried out following operation: (1) terminal is preserved the existing frequency point information that satisfies the frequency decision threshold automatically, and uses and satisfy the preferential frequency of the frequency of frequency decision threshold as the sub-district gravity treatment; For example, resident when successful in frequency A sub-district, only get access to frequency B in the step 304 when satisfying the frequency decision threshold, then with the preferential frequency of frequency B as the sub-district gravity treatment; If get access to frequency B, frequency C etc. when all satisfying the frequency decision threshold, according to the actual needs, can select the preferential frequency of a frequency arbitrarily as the sub-district gravity treatment; Or, select the preferential frequency of the frequency (performance number maximum) of an optimum as the sub-district gravity treatment.Or, (2) terminal continues the residue frequency is carried out frequency sweep, until the equal frequency sweep of frequency in this frequency sub-band is finished, all satisfy the frequency of frequency decision threshold this terminal storage, when needs carried out the sub-district gravity treatment, terminal satisfies from all selected the preferential frequency of the frequency of an optimum as the sub-district gravity treatment the frequency of frequency decision threshold.
In addition, the condition that triggers this sub-district gravity treatment is mainly by two parameters decisions: rise and survey thresholding and gravity treatment thresholding.Rise to survey thresholding and stipulated that when level value reaches a certain set point after terminal begins to initiate the measurement to adjacent sub-district, the gravity treatment thresholding has been stipulated terminal initiation sub-district gravity treatment after level value reaches a certain set point; Need to prove that above-mentioned two concrete values of parameter are issued by network side, and value is by each sub-district decision.Repeat no more in this cell reselection process embodiment of the invention.
It is resident that step 307, terminal attempt carrying out the sub-district at next frequency (frequency B) that satisfies the frequency decision threshold.Wherein, owing to attempt in the step 304 carrying out the sub-district when resident at frequency A, got access to next and satisfied the frequency B of frequency decision threshold, in this step, terminal can be directly resident in the capable sub-district of frequency B.Same, in carrying out this step, also need to continue the residue frequency is carried out frequency sweep, obtain the frequency that satisfies the frequency decision threshold, do not repeat them here.
In the embodiment of the invention, according to the actual needs, when frequency A persistent district is failed, can also select the frequency that satisfies the frequency decision threshold of current optimum, for example, current frequency B and the frequency C of having got access to be when satisfying the frequency decision threshold, and it is resident that this terminal can select the preferred frequency in the two to attempt the sub-district.
In addition, this terminal also needs to judge whether in the resident success in frequency B sub-district, if in the resident success in frequency B sub-district, then carry out to use frequency B to be linked into the step of TD-SCDMA network, similar with step 306, when resident when successful in frequency B sub-district, terminal also can be operated accordingly, for example, terminal is preserved the existing frequency point information that satisfies the frequency decision threshold automatically, and uses and satisfy the preferential frequency of the frequency of frequency decision threshold as the sub-district gravity treatment; Or, terminal continues the residue frequency is carried out frequency sweep, until the equal frequency sweep of frequency in this frequency sub-band is finished, all satisfy the frequency of frequency decision threshold this terminal storage, when needs carried out the sub-district gravity treatment, terminal satisfied the frequency of selecting an optimum the frequency of frequency decision threshold as the preferential frequency of sub-district gravity treatment etc. from all.
Further, when in the resident failure in frequency B sub-district, to continue to carry out this step, it is resident to be that terminal attempts carrying out the sub-district at next frequency (frequency C) that satisfies the frequency decision threshold, the rest may be inferred, until the resident success in sub-district, perhaps, all resident failure of all frequencies that satisfies the frequency decision threshold.Resident when successful when the sub-district, then the resident process in sub-district during this starting up of terminal finishes.And when all resident failure of the frequency that satisfies the frequency decision threshold, will continue execution in step 308.
Concrete, it is resident that this terminal can select optimum frequency to attempt the sub-district from the frequency that can not satisfy the frequency decision threshold, and select during resident failure the frequency of suboptimum to attempt the sub-district in the sub-district resident, and the like, till the resident success in sub-district.
Need to prove, in embodiments of the present invention, when all satisfy the resident failure in the equal sub-district of frequency of frequency decision threshold, it is excessive to illustrate that this frequency decision threshold may be provided with, according to the actual needs, this terminal can reduce the frequency decision threshold, so that the littler frequency of performance number can satisfy the frequency decision threshold, thus the success rate of raising persistent district.
For above-mentioned handling process more clearly is described, with the frequency decision threshold for-75dbm is that example further specifies.In the starting up of terminal frequency sweep process, when the performance number of finding frequency A be-during 70dbm, determine that then frequency A satisfies the frequency decision threshold, then terminal is attempted resident this frequency A sub-district, continues frequency sweep simultaneously, seeks the frequency B that the next one satisfies the frequency decision threshold.Suppose the resident success in frequency A sub-district, and frequency B power is-during 65dbm, then frequency B satisfies the frequency decision threshold, and terminal is preserved the alternative frequency of frequency B information as the sub-district gravity treatment automatically.Suppose the resident failure in frequency A sub-district, and frequency B power is-during 65dbm, then frequency B satisfies the frequency decision threshold, and terminal is attempted frequency B immediately.If successful persistent district then finishes the frequency sweep process, then repeat above-mentioned steps during the resident failure in sub-district.
Wherein, the inventive method can be adjusted each sequence of steps according to actual needs.
As seen, the method that the application of the invention provided, can effectively shorten the time delay of starting up of terminal frequency sweep, make terminal can initiate business as soon as possible, improve user's use experience, in addition, terminal is when a certain frequency trial sub-district is resident, satisfying the frequency of frequency decision threshold by continue seeking next, having reduced because of resident failure and having searched for the employed time delay of frequency again; If the success of certain frequency (frequency A) persistent district can also be satisfied other the alternative frequency of frequency of frequency decision threshold as this terminal sub-district gravity treatment, accelerated the process of sub-district gravity treatment.
The resident equipment in sub-district during a kind of starting up of terminal that the embodiment of the invention also proposes as shown in Figure 4, comprising:
Concrete, described acquisition module 41 also is used for, and according to self business demand the first frequency decision threshold is set; Or, receive from the first frequency decision threshold of network side according to the business demand setting of terminal.
Further, described acquisition module 41 also is used for, according to the CS business setting frequency decision threshold of self; And/or, according to the PS business setting frequency decision threshold of self.
Further, described processing module 43 also is used for, attempt carrying out the sub-district when resident in described terminal at alternative frequency, from the alternative frequency that memory module 44 is preserved, select an alternative frequency, described alternative frequency as resident frequency, and continue to carry out is attempted carrying out the resident operation in sub-district at described resident frequency;
When described terminal need be carried out the sub-district gravity treatment, from the alternative frequency that memory module 44 is preserved, select the preferential frequency of the alternative frequency of an optimum as the sub-district gravity treatment.
Described processing module 43 also is used for, and writes down the frequency of self measuring that can not satisfy described first frequency decision threshold and the described second frequency decision threshold according to the storage thresholding; And when resident frequency and all resident failure of all alternative frequencies, the sub-district is carried out in trial on the frequency that can not satisfy described first frequency decision threshold and the described second frequency decision threshold resident.
Wherein, each module of apparatus of the present invention can be integrated in one, and also can separate deployment.Above-mentioned module can be merged into a module, also can further split into a plurality of submodules.
As seen, the device that the application of the invention provides, can effectively shorten the time delay of starting up of terminal frequency sweep, make terminal can initiate business as soon as possible, improve user's use experience, in addition, terminal is when a certain frequency trial sub-district is resident, satisfying the frequency of frequency decision threshold by continue seeking next, having reduced because of resident failure and having searched for the employed time delay of frequency again; If the success of certain frequency (frequency A) persistent district can also be satisfied other the alternative frequency of frequency of frequency decision threshold as this terminal sub-district gravity treatment, accelerated the process of sub-district gravity treatment.
