To combine accompanying drawing to describe specific embodiment of the present invention in detail below.
Method embodiment
In the present embodiment, provide a kind of sub-district resident implementation method.
At first; The system information buffer area need be set in the terminal; This is set up process and is meant: cause the conversion of resident sub-district, terminal because of the mobility at terminal behind the starting up of terminal; The terminal need be added the cell system information of the resident mistake of success in the cell system information buffer memory to, so that the system information in the later use buffer area is carried out the resident of sub-district.
As shown in Figure 1, the implementation method resident according to the sub-district of present embodiment comprises:
Step S102 carries out at the terminal under the situation of cell selecting or district reselecting, whether comprise in a plurality of system information of subdistricts that preserve at the terminal judges terminal select or the Target cell of gravity treatment (Target cell can be confirmed according to measurement report in advance; It confirms that method is not the emphasis of this paper; Here no longer detail) system information, wherein, a plurality of sub-districts are the resident a plurality of sub-districts of success, terminal; Promptly; A plurality of sub-districts should comprise once successful before at least one resident sub-district, terminal, and the current resident Serving cell in terminal, and the mode of preservation can be a buffer memory;
Step S104; In judged result is under the situation that is; The terminal confirms that the system information of the Target cell whether current system information of the Target cell of present Web broadcast preserves with the terminal is identical, and it is resident to carry out the sub-district in the system information of confirming to utilize under result's situation identical for the system information of the Target cell of preservation (the current system information with) Target cell of preservation.
Through above-mentioned processing; Can make the terminal preserve once resident system information of subdistricts (comprising current resident system information of subdistricts) in advance, after carrying out district reselecting or selecting, whether the system information of the Target cell of preferential judgement selection or gravity treatment preserves on the terminal; And the preferential system information of preserving of utilizing is carried out the resident of sub-district; Thereby can avoid directly obtaining the system information of Target cell to a great extent, reduce the probability that the system information mistake receives, thereby the bursty interference when avoiding real-time acquisition system information from network; Effective solution can't reside in optimum subdistrict owing to wrong receiving system information and cause the follow-up problem of proceeding district reselecting; Save the energy consumption at terminal, reduced the processing burden at terminal, the performance when the lifting terminal is resident.
As shown in Figure 2; When carrying out the cell system information preservation; For each sub-district in pairing 3 sub-districts of system information of terminal preservation; The array of indexes of each sub-district is also preserved at the terminal, comprising: frequency point information (for example, can be ARFCN (the Absolute RF Channel Number of each sub-district; Abbreviate ARFCN as)), the physical label (PhyCell Id) and/or the memory location index (can be described as Index) of system information of subdistricts in the terminal of sub-district; 3 respectively corresponding 1 system informations (that is, the SystemsInfo in the system information buffer memory [0], SystemsInfo [1], SystemsInfo [2]) of location index are so that search stored system information.
In the system information that terminal judges is preserved, whether comprise and selecting or during the system information of the Target cell of gravity treatment; The terminal can obtain the physical label and/or the frequency sign of Target cell from network; In the physical label of a plurality of sub-districts of preserving and/or frequency sign, comprise under the situation of the physical label that obtains and/or frequency sign, judge the system information that comprises Target cell in the system information of preserving.
And; When confirming that at the terminal current system information is whether identical with the system information of the Target cell of preserving; The system information values mark that the terminal need obtain Target cell from network (promptly; Above-mentioned systemInfoValueTag), confirm according to the system information values mark in the system information of the system information values mark that obtains and the Target cell of preservation whether current system information is identical with the system information of the Target cell of preserving.
For example; For the LTE system, when selection or gravity treatment are to certain sub-district at the terminal, at first from network, read the MIB and the SIB1 of this cell system information; And utilize in LTE frequency and the sub-district physical token search system information cache whether this system information of subdistricts is arranged; If system information cache hit, the value mark (systemInfoValueTag) among the SIB1 of inspection storage whether with the SIB1 that obtains in the value mark identical, if both are identical; Directly use the system information in the buffer memory, obtain this system information of subdistricts no longer in real time.
For the 3G system; Can adopt similar processing equally; Difference is that the system information of 3G system has a plurality of system information values marks; Whether one of them part of each mark indication mechanism information changes; Under the corresponding identical situation of all system information values marks of all system information values marks of a system information of confirming from network, to obtain and the system information of preservation, confirm that the system information of obtaining is identical with the system information of preservation, it is resident to utilize the system information of preservation to carry out the sub-district.
In addition; A plurality of system information of subdistricts of preserving at the terminal do not comprise under the system information of the system information of Target cell or the Target cell that definite result is current system information and the preservation situation inequality; The terminal obtains the system information of Target cell from network, and it is resident to utilize the system information of obtaining to carry out the sub-district.
After the terminal had obtained the system information of Target cell and successfully resided in Target cell, the system information of obtaining can be preserved in the terminal.Preserve before the system information of obtaining at the terminal, taken if be used for the memory space of saved system information on the terminal, the terminal covers the system information of oldest stored in the memory space with the system information of obtaining.Thereby the system information that preserve at the assurance terminal is ageing.
Preferably; Sub-district for the resident mistake of terminal success; Its resident order in these sub-districts of terminal sorts to the pairing buffer memory array of indexes of these system information of subdistricts; And the memory location of cell system information can remain unchanged, and wherein, the buffer memory array of indexes of each system information of subdistricts comprises subdistrict frequency point information, physical label and/or the system information of subdistricts memory location index in the terminal of this sub-district.Preferably; The terminal can also further dispose subscript to each buffer memory array of indexes, and through subscript the pairing system information of each buffer memory array of indexes is marked the memory time in the terminal, for example; Can with once the earliest the subscript of the pairing buffer memory array of indexes in the sub-district of resident mistake be configured to 0; After the terminal resides in other sub-districts, just increase buffer memory array of indexes that should the sub-district at every turn, and dispose corresponding subscript, for example; Can with adopt 0,1,2 ..., the mode of n disposes subscript, n representes that the corresponding system information of this subscript is up-to-date stored system information.
For example, the terminal at first resides in first sub-district, and this system information of subdistricts and corresponding buffer memory array of indexes are preserved in the terminal, and the subscript of this array is set to 0; Resident behind second sub-district when the terminal, second system information of subdistricts and corresponding buffer memory array of indexes are preserved in the terminal, and the subscript of this array is set to 1, and at this moment, the ordering of buffer memory array of indexes is 0,1; Resident behind the 3rd sub-district when the terminal, the 3rd system information of subdistricts and corresponding buffer memory array of indexes are preserved in the terminal, and the subscript of this array is set to 2, and at this moment, the ordering of buffer memory array of indexes is 0,1,2; After this resident again behind second sub-district when the terminal, the terminal can utilize second system information of subdistricts of preservation resident in second sub-district again, and according to resident order the ordering of buffer memory array of indexes is adjusted; At this moment; The ordering of buffer memory array of indexes can change into 0,2,1.
That is to say, confirm the memory time of the system message of each sub-district for ease, the buffer memory concordance list can be set the memory space at terminal; In the buffer memory concordance list, can preserve the array of the subdistrict frequency point and the sub-district physical label of resident mistake in chronological order; And each array is provided with subscript, to represent the residence time of each sub-district, for example; Can represent the sub-district of resident mistake the earliest through being designated as 0 array element down; And the like, the array element that is designated as N-1 is down indicated resident sub-district (that is, possibly be current resident sub-district) recently; When the cell system information buffer memory is full, can eliminate down the cell system information that is designated as in the buffer memory that 0 array element indicates.In addition, also can subscript be set to concrete time value or the sign of time, other situation this paper enumerates no longer one by one.
Fig. 3 is the flow chart that in the LTE system, adopts according to the detailed process process of the resident implementation method in the sub-district of present embodiment.As shown in Figure 3, specifically comprise following processing:
Receiving when reading the cell system information request, the system information of certain sub-district (selecting or gravity treatment) need be read in the terminal, at first gets into step 301, searches for the buffer memory array of indexes with subdistrict frequency point and physical label, as if not hitting, then gets into step 302; If can hit, get into step 305.
Buffer memory index value in the temporary array element 0; With buffer memory array of indexes element 1 position that moves forward; Override element 0; The frequency and the physical label of new sub-district are recorded among the array element N-1, simultaneously the buffer memory index value in the temporary array element 0 is recorded in the buffer memory index value of array element N-1, recording cell frequency and physical label are in the corresponding field of array element N-1 simultaneously; Afterwards, read the SI information of sub-district in real time, thereby obtain other required SIB, be cached in the buffer memory of buffer memory index of array element N-1.
Step 304; According to subscript order from small to large; Selected untapped array element in the buffer memory array of indexes; In system information buffer memory array, select a untapped buffer memory, the buffer memory index is saved in the buffer memory index of selected array element, recording cell frequency and physical label are in the corresponding field of selected array element simultaneously; Obtain other SIB in real time, be cached in the buffer memory of selected array element buffer memory index.
To combine instantiation to describe processing procedure of the present invention in detail below.
In the description hereinafter, will under the scene of 4 sub-districts, (comprise sub-district A, B, C and D) with the system information number of cells N of buffer memory is that 3 situation is that example describes.
In conjunction with Fig. 4 and Fig. 5, in this example, suppose to reside in sub-district A behind the starting up of terminal; The frequency of sub-district A and physical label are stored in the buffer memory array of indexes element 0; Cell system information is stored in the system information buffer memory that the buffer memory index field in the buffer memory array of indexes element 0 points to, and in addition, also needs the buffer memory array of indexes subscript of the up-to-date resident cell system information of record storage separately; Be 0 (that is current persistent district) this moment.
A moves to sub-district B from the sub-district for step 11, terminal, need read the system information of sub-district B; The SIB1 of sub-district B is read at the terminal earlier, with frequency and the physical label search buffer memory array of indexes of sub-district B, begins search from array element 0 then; Search Results is the array element of up-to-date persistent district (being current persistent district) for sub-district A; Search is less than the system information corresponding to sub-district B buffer memory, and this moment, the terminal began to obtain SI message in real time to obtain the SIB that other need from wireless channel, successfully obtains behind all required SIB (promptly; The terminal has obtained the system information of sub-district B from network); The terminal resides in sub-district B, and cell system information is saved in the system information buffer memory, and buffer memory array of indexes element 1 is set: sub-district B frequency and physical label are kept in the frequency and physical label field of buffer memory array of indexes element 1; System information buffer memory index is kept in the buffer memory index field in the buffer memory array of indexes element 1, writes down under the buffer memory array of indexes of up-to-date persistent district and be designated as 1.
C moves to sub-district D from the sub-district for step 13, terminal, knows from step 12; The system information buffer memory is full, the system information of buffer memory sub-district D, must eliminate an existing system information of subdistricts in the buffer memory; According to the buffer memory array of indexes record order of design, array index is more little, and the sub-district time of the resident mistake of its record more early; The buffer memory index that element 0 is preserved in the buffer memory array of indexes be the buffer memory of the system information of sub-district A, be the sub-district of resident mistake the earliest, can it be eliminated; Concrete grammar is that the buffer memory array of indexes is moved to the little direction of subscript, overrides array element 0, vacates array element 2; With originally being used for the system information that the buffer memory of buffer memory sub-district A system information is used for preserving sub-district D, frequency and physical label that buffer memory array of indexes element 2 comes recording cell D are set, and recording cell d system information cache index.
In conjunction with Fig. 6 and Fig. 7; In this example; Suppose to reside in sub-district A behind the starting up of terminal, the frequency of sub-district A and physical label are stored in the buffer memory array of indexes element 0, and cell system information is stored in the system information buffer memory of the buffer memory index in the buffer memory array of indexes element 0; Need the buffer memory array of indexes subscript of the up-to-date resident cell system information of record storage separately in addition, be 0 (being current persistent district) this moment.
Instance 3
With reference to Fig. 8 and Fig. 9; Suppose to reside in sub-district A behind the starting up of terminal; The frequency of sub-district A and physical label are stored in the buffer memory array of indexes element 0; Cell system information is stored in the system information buffer memory of the buffer memory index in the buffer memory array of indexes element 0, needs the buffer memory array of indexes subscript of the up-to-date resident cell system information of record storage separately in addition, and be 0 (being current persistent district) this moment.
B returns sub-district A from the sub-district for step 32, terminal, and the SIB1 of sub-district A is read at the terminal earlier; With frequency and the physical label search buffer memory array of indexes of sub-district A, begin search from array element 0 then, the hunting zone is to the array element of indicating current persistent district 1; Can search buffer memory array of indexes element 0 information of sub-district A is arranged; Whether the value mark that relatively obtains among the system information SIB1 of sub-district B of value mark and buffer memory among the SIB1 identical, find inequality after, obtain SI message in real time to obtain other SIB of sub-district A from wireless channel; The buffer memory of updated stored sub-district A system information; Adjustment buffer memory array of indexes, the buffer memory array of indexes element 0 of earlier temporary sub-district A is with the buffer memory index information array element 1 of the recording cell B position that moves forward; Vacate buffer memory array of indexes element 1 position, the buffer memory array of indexes information of sub-district A is put into wherein.
Through above-mentioned processing; Can make the terminal preserve once resident system information of subdistricts (comprising current resident system information of subdistricts) in advance, after carrying out district reselecting or selecting, whether the system information of the Target cell of preferential judgement selection or gravity treatment preserves on the terminal; And the preferential system information of preserving of utilizing is carried out the resident of sub-district; Thereby can avoid directly obtaining the system information of Target cell to a great extent, reduce the probability that the system information mistake receives, thereby the bursty interference when avoiding real-time acquisition system information from network; Effective solution can't reside in optimum subdistrict owing to wrong receiving system information and cause the follow-up problem of proceeding district reselecting; Save the energy consumption at terminal, reduced the processing burden at terminal, the performance when the lifting terminal is resident; System information through to each message of preserving is carried out time-labeling, can also further express resident time of sub-district and situation, has enriched the function at terminal.
