Description
Technical field
The present invention relates to wireless communication field, particularly mobile device cell selecting technical field in the wireless communication system specifically is meant the method that a kind of mobile communication equipment realization multi-band multi-access technology district initiation is selected.
Background technology
Wireless communication system mainly comprises GSM and two kinds of forms of CDMA at present.Operate at present in the gsm system, normally used is the solution of the double frequency-band of 900M and 1800M.And for cdma system, International Telecommunication Union has formulated a plurality of frequency ranges that cdma system can be used, though in China owing to the reason of telephone traffic has only been used frequency band 0, but along with being on the increase of number of users, in cdma system, only use a frequency range not meet consumers' demand, it is more and more nervous that local resource will inevitably become, and therefore will inevitably use a plurality of frequency bands to provide service as the user simultaneously as gsm system.
After the mobile device start, the PLMN (PLMN) that it can attempt to allow with the SIM/USIM card is got in touch, therefore mobile device will be selected a proper cell, and from this sub-district, obtain the parameter of control channel and other system configuration information, this selection course is called as the sub-district and is stationed.
Be stationed in order to carry out the sub-district when mobile device is started shooting, it will at first carry out the measurement of full range band, and purpose is to search available Target cell and be stationed.In gsm system, mobile device will at first be searched for the RF channel of 124 GSM900 frequency ranges, if support double frequency-band then search for the radio-frequency channel of 374 GSM1800 frequency ranges again, and on each RF channel, read the signal strength signal intensity of reception, calculate average level, whole measuring process will continue 3～5s, during this period of time will extract 5 from different RF channels at least respectively and measure sampling point.
Mobile device will be tuned on the carrier wave of incoming level maximum, judge at first whether this carrier wave is Broadcast Control Channel (BCCH) carrier wave (by searching the FCCH burst), if travelling carriage will be attempted decoding synchronizing channel (SCH) and come with this carrier synchronization and read system broadcast message on the Broadcast Control Channel (BCCH).If mobile device can be correctly decoded the data of Broadcast Control Channel (BCCH), and when data show this sub-district belong to selected public mobile communication net (PLMN), parameters C 1 value greater than 0, this sub-district is not under an embargo the access grade of access, travelling carriage when not forbidden by this sub-district, travelling carriage can be selected this sub-district.Otherwise, mobile device will be tuned to repeat above the trial on time high carrier wave, up to finding available sub-district.
The path loss criterion of parameters C 1 for being stationed for the sub-district, the C1 of Serving cell must be greater than 0, and its formula is as follows:
C1＝RXLEV-RXLEV_ACCESS_MIN-MAX((MS_TXPWR_MAX_CCH-P)，0)
Unit: dBm
Wherein:
● RXLEV is the average level that travelling carriage receives
● the minimum incoming level of RXLEV_ACCESS_MIN for allowing travelling carriage to insert
● spendable maximum transmit power level when MS_TXPWR_MAX_CCH is the travelling carriage connecting system
● P is the peak power output of travelling carriage
If do not find proper cell yet after 30 radio-frequency channels the strongest are all searched, then mobile device will continue all RF channels of monitoring, search C1 is greater than 0 and the Broadcast Control Channel (BCCH) that is not under an embargo and inserts, after finding this carrier wave, mobile device will be stationed this sub-district, and do not consider public mobile communication net (PLMN) information, this moment, mobile device was only supported urgent call.
And for cdma system, the sub-district is stationed and probably is divided into following components and realizes:
(1) Cell searching
The purpose of Cell searching is to find a proper cell, and obtains its synchronous channel information, and general steps is as follows:
(a) slot synchronization
Because the synchronous code of all primary synchronization channels (SCH) all is identical in universal terrestrial access network (UTRAN), and sends in preceding 256 chips of each time slot (slot), all is identical in each time slot (slot).Mobile device uses a matched filter to obtain the synchronous of time slot.
(b) frame synchronization
Will carry out frame synchronization after the slot synchronization, frame synchronization is to use the synchronous code of auxiliary synchronization channel (SCH) to realize, the synchronous code one of auxiliary synchronization channel (SCH) has 16, in each time slot, be different, difference according to code word in each time slot forms 64 group code sequences, it is that result after their cyclic shift is unique that this 64 group code sequence has a characteristic, therefore mobile device just uses one by one and the signal that receive of this 64 group code sequence to carry out related operation, and the used secondary synchronization sequences in this sub-district of that of correlation maximum has also been determined the scrambler group and the frame synchronization of this sub-district simultaneously.
(c) main scrambler obtains
Have 8 main scramblers in the scrambler group, mobile device is gone up the scrambler that uses with each scrambler and Common Pilot Channel (CPICH) in the scrambler group and is carried out correlation computations, and the scrambler of correlation maximum is exactly the main scrambler of this sub-district.
(2) read broadcast channel
Owing in step 1, obtained the synchronizing information of this sub-district, just can obtain the information on the broadcast channel of this sub-district according to this information, general steps is as follows:
(a) Master Information Block (MIB's) obtains
The reference and the schedule information of the most of system information block in the sub-district have been provided in the Master Information Block, wherein also may comprise reference and schedule information to one or two Scheduling Block, be the reference and the schedule information of all additional system information blocks of not providing of other main information and this one or two Scheduling Block provides.Transmission and its scheduling in Master Information Block cycle on broadcast channel are static.Schedule information except other system block of information (SIB) and Scheduling Block, main information also comprises PLMN (PLMN) information, if judge that current PLMN information of obtaining and the PLMN that will be stationed the sub-district at present are inconsistent then restart the sub-district and be stationed process.
(b) system information block (SIB's) obtains
Mobile device just can obtain other system block of information according to the schedule information among the MIB after reading MIB.Be stationed for the sub-district, the system information block type 3 (SIB3) of topmost system information block comprises the sub-district in this block of information and is stationed information parameter, and is as shown in table 1.Calculate according to following formula then:
Squal＝Qqualmeas-Qqualmin
Srxlev＝Qrxlevmeas-Qrxlevmin-Pcompensation
Wherein, the implication of each parameter sees the following form 1:
| Squal | Mass value is stationed in the sub-district |
| Srxlev | The received signal level value is stationed in the sub-district |
| Qqualmeas | Mass value is stationed in the sub-district that measures under the CPICH Ec/N0 pattern |
| Qrxlevmeas | Level value is stationed in the sub-district that measures under the CPICH RSCP. pattern |
| Qqualmin | Can received signal quality minimum value |
| Squal | Mass value is stationed in the sub-district |
| Qrxlevmin | Can received level minimum value |
| UE_TXPWR_MAX_RACH | Maximum transmission power on the up channel |
| P_MAX | The maximum transmission power of mobile device |
| Pcompensation | Max(UE_TXPWR_MAX_RACH-P_MAX，0) |
If Squal＞0 is Srxlev＞0 simultaneously, then mobile device thinks that this sub-district is that proper cell is resident gets off and read other needed system informations, and the sub-district is stationed successfully; Be enough to condition if be discontented with, then restart the sub-district and be stationed process.
From above-mentioned explanation, can calculate, mobile device for the double frequency of supporting GSM900/1800, the RF channel that need measure during start has 498, and each channel guarantees that at least 5 are measured sampled point, then needs to measure 2490 sampled points when the measurement of whole full range band is finished altogether.If but for initial cell is stationed, can not need to measure (no matter be the full range band or selected certain frequency band in advance), but directly determine Target cell and be stationed successfully that spent resource was very little when this started shooting for mobile device according to canned data.
And for cdma system, mode also is to adopt the mode of being stationed again of measuring earlier usually, and along with the continuous increase of cdma system number of users, adopting the multiband support is the choosing of certainty, and the thing followed is measured cost will be increased greatly.Though there are very big difference in cdma system and gsm system, be consistent on the principle for the selection of control cell initial, also will there be the problem that is similar to gsm system during its start initial selected sub-district.
In sum, the mode that adopts traditional elder generation to measure to be stationed again is to power consumption, the available machine time of mobile device and to assess the cost all be great consumption, will increase considerably the use cost of mobile device.
