Description
Technical field
The present invention relates to CDMA mobile communication system, relate in particular to a kind of system and method for the CDMA of realization Public Long Code Mask.
Background technology
In CDMA mobile communication system, Public Long Code Mask PLCM is used to distinguish the reverse traffic channel of different user, and the cycle of long code is 2
42-1 chip, and satisfy the linear recurrence formula that following proper polynomial defines: p (x)=x
42+ x

2+ x+1, the pseudo random sequence PN chip of each 42 bit long code are mould 2 inner products of the sequencer state vector of the mask of 42 bits and 42 bits.When Long Code Mask during based on ESN, for public Long Code Mask, bit M31 to M0 should be rearranging of terminal electronic sequence number ESN bit, and this aligning method is as follows:
ESN＝(E31，E30，E29，E28，E27，E26，E25，...，E2，E1，E0)
The ESN bit is rearranged, obtain (E0, E31, E22, E13, E4, E26, E17, E8, E30, E21, E12, E3, E25, E16, E7, E29, E20, E11, E2, E24, E15, E6, E28, E19, E10, E1, E23, E14, E5, E27, E18, E9).
Bit M41 to M32 should be changed to " 1100011000 ".
For base station sub-system is version number less than 11 network, and machine engages a terminal and generates Public Long Code Mask PLCM by Electronic Serial Number ESN; The separation between machine and card terminal generates Public Long Code Mask PLCM by subscriber identification module identification number UIMID.Along with the exhaustion of ESN number resource, the reverse traffic channel of different user can't can't effectively be distinguished based on ESN or UIMID generation Public Long Code Mask PLCM less than 11 system by base station sub-system version number at present, can't realize normal talking.
Machine engages a terminal not during raise-position, adopts ESN to generate PLCM; Can be after the raise-position according to the PLCM mode that terminal rank banner message is provided with and base station sub-system is supported, adopt based on pESN (pseudo-ESN) or based on the PLCM generating mode of non-32 bits.The separation between machine and card terminal during raise-position, does not adopt UIMID to generate PLCM; Can be after the raise-position according to the PLCM mode that terminal rank banner message is provided with and base station sub-system is supported, adopt based on pUIMID (pseudo-UIMID) or based on the PLCM generating mode of non-32 bits.
After the following describes the card number raise-position, in the prior art about two kinds of processing modes of PLCM.
Mode one: the network mode of not upgrading, introduce pUIMID, pESN number
The manner separation between machine and card terminal is introduced the pUIMID number, and promptly ICCID to 24bit, and adds 8 bit prefix and the not exclusive 32bits number pUIMID that forms by the SHA-1 compression algorithm.
The manner machine engages a terminal and introduces the pESN number, and promptly mobile device identification code (MEID) to 24bit, and adds 8 bit prefix and the not exclusive 32bits number pESN that forms by the SHA-1 compression algorithm.
PUIMID and pESN replace UIMID, ESN to participate in the generation of PLCM respectively.
Mode two: network upgrade, avoid the PLCM conflict
The manner is applicable to that before the cdma2000 version d, the network equipment carries out the situation of software upgrading.In the case, network authentication still adopts pESN or pUIMID to replace UIMID to participate in authentication, but the Long Code Mask generation realizes different modes by terminal tenability and base station sub-system tenability through negotiation.
But the network software upgrading has mainly increased by three major functions, be respectively: terminal increases SCM (StationClass Mark, the terminal class emblem) whether the 5th bit identification terminal supports Early MEID, uses StatusRequest/Response (status poll/condition responsive) information reporting MEID information and the use PLCM generating mode based on non-32 bits.
Employing mainly contains three kinds of BS_assigned (base station sub-system distribution), IMSI_based (based on international mobile subscriber identity), MEID_based (based on MEID) based on the PLCM generating mode of non-32 bits, the true BS_assigned of the employing PLCM of most producers generates Long Code Mask, has guaranteed that the PLCM conflict does not take place network.
Existing international standard C.S.0072 and C.S.0073 have made further regulation to Public Long Code Mask PLCM, and when SCM the 5th bit equaled 1, termination number was MEID, and terminal is supported the PLCM generating mode based on non-32 bits simultaneously; When SCM the 5th bit equaled 0, termination number was ESN, and terminal is supported the PLCM generating mode based on 32 bits simultaneously, i.e. termination number raise-position is to MEID, and termination function is upgraded simultaneously and supported PLCM generating mode based on non-32 bits.According to this regulation, the upgrading of network and terminal synchronizes can guarantee that then terminal takes the PLCM generating mode based on non-32 bits.Because the ESN number resource is about to exhaust at present, need enable MEID immediately; And for the protecting network equipment investment, network upgrade needs a period of time, so network and terminal staging can't keep carrying out synchronously.When terminal is upgraded early than base station sub-system, the interoperability problem may appear, and such as the new terminal that upgrade of network not may nonrecognition SCM the 5th bit equals 1, terminal is access network normally; The new terminal of having upgraded has been dispersed in user's hand when network upgrade, and whether it supports upgrade of network smoothly to be difficult to validation test one by one.
