Description
Technical field
The present invention relates to wireless communication system, relate to a kind of in particular in the transmission customer equipment identification of wireless communication system and the equipment and the method for user profile.
Background technology
Now, 3GPP standardization body has set about beginning its existing system standard is carried out long-term evolution (LTE, Long Term Evolution).In the middle of numerous physical layer transmission technology, based on OFDM (OFDM, Orthogonal Frequency DivisionMultiplexing) downlink transfer technology and be the focus of research based on the uplink technology that single-carrier frequency division multiple access inserts (SCFDMA, Single Carrier Frequency Division Multiple Addressing).Be a kind of multi-carrier modulation communication technology on the OFDM technological essence, its basic principle is the data flow of a two-forty to be decomposed into several rate data streams transmit simultaneously on one group of mutually orthogonal subcarrier.The OFDM technology is because its multicarrier character has performance advantage aspect a lot.It on the SCFDMA technological essence a kind of single carrier transmission technology, its signal peak-to-average is than (PAPR, Peak to Average Power Ratio) lower, thereby the power amplifier of portable terminal can be with higher efficient work, enlarge the coverage of sub-district, by adding Cyclic Prefix (Cyclic Prefix) and frequency domain equalization, it is lower that it handles complexity simultaneously.
According to existing discussion result about LTE, be LTE system descending frame structure as shown in Figure 1, Radio Resource in the LTE system is meant time and the frequency resource that system or subscriber equipment can take, can (101-103) do differentiation with radio frames (radio frame) for unit, the time span of radio frames is identical with the time span of the radio frames of WCDMA system, and promptly its time length is 10ms; Each frame is subdivided into a plurality of subframes (sub-frame) (104-107), and present hypothesis is that each radio frames comprises 20 subframes, and the time span of subframe is 0.5ms; Each subframe comprises a plurality of OFDM symbols again, and according to present hypothesis, the time span of effective OFDM symbol is about 66.7 μ s in the LTE system.The time span of the CP of OFDM symbol can have two kinds, promptly the time span of short CP is approximately 4.8 μ s, the about 16.7 μ s of the time span of long CP, long CP subframe is used for many Cell Broadcast CB/multicasts and the very large situation of radius of society, short CP subframe (108) comprises 7 OFDM symbols, and long CP subframe (109) comprises 6 OFDM symbols.The minimum transfer time interval, (TTI) just equaled the time span of subframe.
Fig. 2 is a LTE system uplink frame structure, and with the downlink frame similar, the time span of its radio frames (201,202,203) is all 10ms mutually with WCDMA; Each frame is subdivided into a plurality of subframes (204-207), and present hypothesis is that each radio frames comprises 20 subframes, and the time span of subframe is 0.5ms; Each subframe comprises a plurality of SCFDMA symbols again, according to present hypothesis, SCFDMA symbol in the LTE system is divided into two kinds, comprise two short symbols (214 in the subframe, 215), length effective time of each short symbol is about 33.33 μ s, is called short block (Short block) in the current discussion; Comprise 6 long symbols (208～213) in a subframe simultaneously, each long symbol length effective time is 66.67 μ s, is called long piece (Long block) in the current discussion.Short symbol is used to transmit the reference information of coherent demodulation, also can be used for transmit ascending data and control information simultaneously; Long symbol is used for transmit ascending data and control information.The minimum transfer time interval, (TTI) just equaled the time span of subframe.
In existing 3GPP system,, multiple different user ID can be arranged according to subscriber equipment present located state.For the subscriber equipment of idle condition, system is to use the identifier as subscriber equipment such as interim identification code (TMSI) of international mobile subscriber identity (IMSI) or user, and the general bit number of this class user ID is many.Set up the subscriber equipment that is connected for current with network, its identifier can be cell-radio network temporary identifier (C-RNTI) or UTRAN radio network temporary identifier (UTRAN RNTI, U-RNTI) etc., the general bit number of this class user ID is fewer.
According to existing 3GPP standard, IMSI can comprise 6 to 21 bit digital, is the structure of IMSI as shown in Figure 3, and it is made up of three parts: mobile subscriber belonging country code name (MCC), mobile network number (MNC) and mobile identification number (MSIN).Wherein, the MCC of China is 460, and the MNC of China Mobile is 00, and the MNC of CHINAUNICOM is 01.Like this, preceding 5 of the IMSI of China Mobile, promptly MCC and MNC are 46000; Preceding 5 of the IMSI of CHINAUNICOM is 46001.
In the WCDMA system, subscriber equipment reduces power consumption by carrying out discontinuous reception (DRX) under idle condition.Subscriber equipment only needs to monitor paging indication information a moment in a DRX cycle like this.In the WCDMA system, DRX cycle is 2
kIndividual radio frames, k=0 wherein, 1,2 ....Subscriber equipment can be attached to a plurality of core network domain simultaneously in addition, and different at the DRX cycle of each core network domain, and at this moment subscriber equipment is monitored paging indication information according to the minimum value in each DRX cycle.Subscriber equipment is the position (PagingOccasion) of determining to monitor paging information according to the number K of the inferior Common Control Channel (SCCPCH) of its IMSI, bearing call channel (PCH), System Frame Number (SFN) and DRX cycle, promptly monitor the radio frames of paging information
Paging_Occasion＝(IMSI?div?K)mod?DRX_cycle_length+n*DRX_cycle_length
Wherein, n=0,1,2 ..., as long as the value of the SFN that calculates is less than its maximum.In the radio frames of the monitoring paging information that calculates according to above-mentioned formula, the paging indication PI that subscriber equipment need be monitored determines based on IMSI equally, PI=DRX_index mod Np, wherein, DRX_index=IMSI div8192, Np are the numbers of the paging indicating bit of transmission in each radio frames, can be 18,36,72,144.
According to the discussion result of current LTE about non-synchronized random access channel, Fig. 4 is an example of the interaction flow of current non-synchronized random access.As shown in Figure 4, subscriber equipment at first sends random access information (401) to the network equipment, according to current discussion result, this step (401) only sends arbitrary access front signal, the amount of information that can carry in the arbitrary access front signal is very limited, the information of transmission 4～8 bits that subscriber equipment can imply by arbitrary access front signal.Next the arbitrary access front signal of the possible subscriber equipment of network measuring, and with the threshold value of setting relatively, when finding that one or more arbitrary access front signal surpasses threshold value, network sends accidental access response information (402), comprise the Timing Advance that calculates according to arbitrary access front signal, for subscriber equipment sends the ascending resource of follow-up distribution, and other information etc.Then subscriber equipment sends the used resource judgment network of random access information according to it and sends the moment of accidental access response information for it, and in this moment receiving random access response information.When subscriber equipment had been received the response message of negating, the bottom module of subscriber equipment was notified its high-rise module NACK messages and is stopped random access procedure, and the user can postpone to initiate random access procedure again after a period of time; When subscriber equipment was not received any response message that sends to it, subscriber equipment resend random access information or initiating random access procedure again after delay a period of time on the next random access resource; When subscriber equipment had been received sure response message, subscriber equipment was random access information and other information (403) of sending on the ascending resource of its distribution at network.After the network equipment is received the random access information and other information that subscriber equipment sends, continue to finish follow-up operation (404) alternately with subscriber equipment.
In communication system, sometimes need to send the known information of some recipients, typical example is that network is when sending descending shared control signaling, for the control signaling that identifies current transmission is at that subscriber equipment, network comprises customer equipment identification in the control information of its transmission, thereby whether subscriber equipment can send to oneself according to the user ID distinguishing signaling in the control signaling.To control signaling institute at subscriber equipment, this customer equipment identification that sends in controlling signaling is a kind of known information.
Network sends customer equipment identification in the control signaling method has two kinds.First method is that customer equipment identification is calculated CRC with other control informations, then the CRC of customer equipment identification, other control informations and calculating is constituted control information piece and coding transmission together; The recipient, subscriber equipment is at first to the control signaling decoding, and check (CRC) judges according to the user ID in the control signaling whether this control signaling sends to it then.To be networks calculate CRC to the control information of each subscriber equipment to second class methods, and the sign of subscriber equipment is by the implicit transmission of this CRC, thereby do not need explicit to send this customer equipment identification in the control signaling.The recipient, subscriber equipment judges according to the control information bit in the control signaling of receiving, CRC bit and its customer equipment identification whether network is that it has sent control information to after controlling signaling decoding.
According to the discussion result of 3GPP to the control channel of HSDPA, the method for second kind of above-mentioned transmission user device identification has two kinds of processing modes at least.First kind of mode is that CRC is calculated in network based other control informations except that user ID, then user ID is done the mask operation with the CRC that calculates, network sends other control information bits and the mask operation CRC bit afterwards except that user ID then.The second way is that CRC is calculated in network based user ID and other control informations, and network sends other control information bits and the CRC bit that calculates except that user ID then.
The overhead bit of first kind of above-mentioned network method of transmission customer equipment identification in the control signaling is bigger, because it is the explicit transmission of user ID; The overhead bit of second kind of above-mentioned network method of transmission customer equipment identification in the control signaling is smaller, but it only is applicable to the situation of the length of user ID smaller or equal to the length of CRC, and the possibility that adopts this method to cause flase drop to be surveyed increases.

Embodiment
In the communication system for the information that identifies transmission at subscriber equipment, network need send known control information, for example at the sign of a subscriber equipment, perhaps at one group of user's sign, perhaps at all users' sign.The present invention proposes when the bit number of this part Given information processing method during greater than the length of the CRC that will add.Basic handling principle of the present invention is: network is the explicit transmission of a part of bit of recipient's Given information, and network passes through another part bit of recipient's Given information the transmission of the CRC bit implicit expression of being added simultaneously.Here, explicit transmission is meant the known bit that comprises this part recipient in the block of information that network sends, thereby carries out chnnel coding and send with other information bits; The transmission of implicit expression is meant the known bit that does not comprise this part recipient in the block of information that network sends, the information of having carried this part bit on the CRC that network adds.Because the known information of this part recipient play information institute that marked network sends at the effect of subscriber equipment, in order to describe simply, below they are referred to as user totem information.
Method one:
The first method that network of the present invention sends user totem information and user profile comprises the steps:
A) network is designated as first and second portion to the bit separated into two parts of user totem information;
B) first's bit of network based user totem information and user profile bit calculate CRC;
C) network is done the mask operation to the second portion bit of user totem information with the CRC that calculates, and generally is mould 2 add operations;
D) CRC after network is operated first's bit of user totem information, user profile bit and mask encodes and sends.
According to method of the present invention, when the user totem information of network transmission is the IMSI of subscriber equipment, network is divided into two parts to IMSI, thereby calculates CRC according to first's bit and the user profile of IMSI, and the second portion bit of IMSI and CRC are done the mask operation.The present invention not limiting network divides which bit among the IMSI as the second portion bit.
According to the formation of IMSI, network can be the second portion bit of the some or all of bit of MCC among the IMSI and MNC as IMSI.If the bit number of CRC equals total bit number of MCC and MNC, network can be done the mask operation to all bits of MCC and MNC as the second portion bit of IMSI and CRC.If the bit number of CRC is less than total bit number of MCC and MNC, network can be done the mask operation to a part of bit of MCC and MNC as second portion bit and the CRC of IMSI.For example, suppose that CRC is 16 bits, MCC and MNC be 5 numerals altogether, i.e. 20 bits, and at this moment network can be the second portion bit of corresponding 16 bits of the numeral of 3 numerals of MCC and MNC as IMSI; Suppose that CRC is 12 bits, network can be the second portion bit of 12 bits of 3 numeral correspondences of MCC as IMSI; Suppose that CRC is 8 bits, network can be the second portion bit of 8 bits of 2 numeral correspondences of MCC as IMSI.If the bit number of CRC is greater than total bit number of MCC and MNC, network can be done the mask operation to the bit of the bit of MCC and MNC correspondence and a part of MSIN correspondence as second portion bit and the CRC of IMSI.For example suppose that CRC is 24 bits, MCC and MNC be 5 numerals altogether, i.e. 20 bits, and at this moment network can be the second portion bit of corresponding 24 bits of the numeral of 5 numerals of MCC and MNC and MSIN as IMSI.
To the situation of paging channel, network based IMSI divides into groups to subscriber equipment, thereby obtains the position (Paging occasion) that subscriber equipment is monitored paging information, promptly detects the radio frames or the subframe of paging information.Suppose that network based IMSI divides 2 to subscriber equipment
kIndividual group, thus difference corresponding 2
kThe position of individual detection paging information, and the bit of the k among the IMSI determined this 2
kIndividual group division.First method of the present invention is that network is done the mask operation to the some or all of second portion bit and the CRC as IMSI of other bits beyond k the bit that is used to divide into groups.The number of other bits beyond the k that is used to the divide into groups bit is during more than or equal to the length of CRC, and network is got wherein CRC_length bit as the second portion bit of IMSI; The number of other bits beyond the k that is used to the divide into groups bit is during less than the length of CRC, and network is the second portion bit of the part of other bits beyond k the bit that is used to divide into groups and k bit being used to divide into groups as IMSI.Second method of the present invention is that network is done the mask operation to the some or all of second portion bit and the CRC as IMSI of k the bit that is used to divide into groups.As k during more than or equal to the length of CRC, network is got CRC_length bit in this k bit as the second portion bit of IMSI.As k during less than the length of CRC, first kind of processing mode is network the second portion bit of other CRC_length-k bit of dividing k bit detecting the paging information position and IMSI as IMSI.As k during less than the length of CRC, second kind of other bits and other paging information bits calculating CRC that processing mode is network based IMSI except that an above-mentioned k bit, and the bit sequence coding that network is formed above-mentioned k bit obtains CRC_length bit, and does the mask operation with CRC.Here Bian Ma principle is the minimum distance maximum that makes CRC_length bit behind the coding.
Suppose that network based IMSI divides 2 to subscriber equipment
kIndividual group, thus difference corresponding 2
kThe position of individual detection paging information, as k during less than the length of CRC, the bit of the CRC_length among the network based IMSI determines to detect the position of paging information.At this moment be actually 2
CRC_lengthIndividual bit sequence is divided into 2
kThe group, the principle of grouping be make this 2
kThe minimum distance maximum of each bit sequence in individual group of each group.Network is the second portion bit of this CRC_length bit among the IMSI as IMSI, thereby first's bit of network based IMSI and other paging information bits calculate CRC, and second portion bit and the CRC as IMSI done the mask operation.A kind ofly realize that the method for above-mentioned grouping is table of the network storage, record 2
CRC_lengthIndividual bit sequence is to the mapping relations of its affiliated group.Another method is the algorithm that the network definition is determined, thereby by calculating 2
CRC_lengthGroup under the individual bit sequence.
According to method of the present invention, when the user totem information of network transmission is the TMSI of subscriber equipment, network is divided into two parts to TMSI, thereby calculates CRC according to first's bit and the user profile of TMSI, and the second portion bit of TMSI and CRC are done the mask operation.The present invention not limiting network divides which bit among the TMSI as the second portion bit.
For paging channel, supposing the system is fixing to detect the radio frames or the subframe of paging information according to IMSI to definite its of subscriber equipment grouping, in order to guarantee in the moment that sends paging information, the minimum distance maximum of the second portion bit of each TMSI that network sends, a kind of method is that network is in distribution T MSI, according to the grouping situation distribution T MSI under the IMSI of subscriber equipment, the subscriber equipment of phase IMSI is on the same group guaranteed as far as possible the code distance maximization of the TMSI of its distribution.That is to say, if network is divided into 2 to subscriber equipment based on IMSI
kGroup, at this moment network also is divided into 2 to TMSI accordingly
kIndividual group, and the minimum distance maximum of the second portion bit of each TMSI in each group.Network can be provided with the corresponding relation between these groups, when IMSI belongs to certain group, and distribution T MSI during network is preferentially organized to corresponding TMSI.
Method two:
The second method that network of the present invention sends user totem information and user profile comprises the steps:
A) network is designated as first and second portion to the bit separated into two parts of user totem information;
B) whole bits of network based user totem information and user profile bit calculate CRC;
C) network is encoded to first's bit, the user profile bit of user totem information and the CRC that calculates and is sent.
According to method of the present invention, when the user totem information of network transmission is the IMSI of subscriber equipment, network is divided into two parts to IMSI, thereby whole bits and user profile according to IMSI are calculated CRC, but only send first's bit, the user profile bit of IMSI and the CRC bit that calculates, and the second portion bit of no longer explicit transmission IMSI.The present invention not limiting network divides which bit among the IMSI as the second portion bit.
According to the formation of IMSI, network can be the second portion bit of the some or all of bit of MCC among the IMSI and MNC as IMSI.If the bit number of CRC equals total bit number of MCC and MNC, network can be the second portion bit of all bits of MCC and MNC as IMSI, thus no longer explicit transmission.If the bit number of CRC is less than total bit number of MCC and MNC, network can be the second portion bit of a part of bit of MCC and MNC as IMSI, thus no longer explicit transmission.For example, suppose that CRC is 16 bits, MCC and MNC be 5 numerals altogether, i.e. 20 bits, and at this moment network can be the second portion bit of corresponding 16 bits of the numeral of 3 numerals of MCC and MNC as IMSI; Suppose that CRC is 12 bits, network can be the second portion bit of 12 bits of 3 numeral correspondences of MCC as IMSI; Suppose that CRC is 8 bits, network can be the second portion bit of 8 bits of 2 numeral correspondences of MCC as IMSI.If the bit number of CRC is greater than total bit number of MCC and MNC, network can be the second portion bit of the bit of the bit of MCC and MNC correspondence and a part of MSIN correspondence as IMSI, thus no longer explicit transmission.For example suppose that CRC is 24 bits, MCC and MNC be 5 numerals altogether, i.e. 20 bits, and at this moment network can be the second portion bit of corresponding 24 bits of the numeral of 5 numerals of MCC and MNC and MSIN as IMSI.
To the situation of paging channel, network based IMSI divides into groups to subscriber equipment, thereby obtains the position (Paging occasion) that subscriber equipment is monitored paging information, promptly detects the radio frames or the subframe of paging information.Suppose that network based IMSI divides 2 to subscriber equipment
kIndividual group, thus difference corresponding 2
kThe position of individual detection paging information, and the bit of the k among the IMSI determined this 2
kIndividual group division.First method of the present invention is a network the some or all of second portion bit as IMSI of k the bit that is used to divide into groups other bits in addition, thus no longer explicit transmission.The number of other bits beyond the k that is used to the divide into groups bit is during more than or equal to the length of CRC, and network is got wherein CRC_length bit as the second portion bit of IMSI; The number of other bits beyond the k that is used to the divide into groups bit is during less than the length of CRC, and network is the second portion bit of the part of other bits beyond k the bit that is used to divide into groups and k bit being used to divide into groups as IMSI.Second kind of processing method be network the some or all of second portion bit of k the bit that is used to divide into groups as IMSI, thereby no longer explicit transmission.As k during more than or equal to the length of CRC, network is got CRC_length bit in this k bit as the second portion bit of IMSI.As k during less than the length of CRC, first kind of processing mode is network dividing k bit detecting the paging information position second portion bit as IMSI.As k during less than the length of CRC, second kind of processing mode is network the second portion bit of other CRC_length-k bit of dividing k bit detecting the paging information position and IMSI as IMSI.
According to method of the present invention, when the user totem information of network transmission was the TMSI of subscriber equipment, all bits of network based TMSI and other information bits calculated CRC, then a part of bit of the only explicit transmission of network TMSI.
According to method of the present invention, when the user totem information of network transmission is the TMSI of subscriber equipment, network is divided into two parts to TMSI, thereby whole bits and user profile according to TMSI are calculated CRC, but only send first's bit, the user profile bit of TMSI and the CRC bit that calculates, and the second portion bit of no longer explicit transmission TMSI.The present invention not limiting network divides which bit among the IMSI as the second portion bit.
Method three:
The third method that network of the present invention sends user totem information and user profile comprises the steps:
A) network is designated as first and second portion to the bit separated into two parts of user totem information;
B) network is to the user totem information computation of parity bits;
C) first's bit of network based user totem information, user profile bit and check bit calculate CRC;
D) network is done the mask operation to the second portion bit of user totem information with the CRC that calculates, and generally is mould 2 add operations;
E) CRC after network is operated first's bit of user totem information, user profile bit, check bit and mask encodes and sends.
Network is encoded to user totem information in the step b) of the present invention, and a kind of method is user totem information to be added the strange/even parity check bit of a bit.All bits that a kind of mode is network based user totem information calculate strange/even parity check bit.Another transmission is that the second portion bit of network based user totem information calculates strange/even parity check bit.
Method four:
The 4th kind of method that network of the present invention sends user totem information and user profile comprises the steps:

Second embodiment
Present embodiment has provided the application example of the present invention in the non-synchronized random access procedure.
Because non-synchronized random inserts the transmission policy that is based on competition, so might adopt identical targeting signal to initiate transmission simultaneously more than a subscriber equipment, at this moment collision has just taken place, the resource that the competition of just a plurality of subscriber equipmenies is identical, but this resource that takies that a subscriber equipment can success is arranged at the most.Like this, system must provide a kind of mechanism of collision detection, is used to the subscriber equipment of confirming that current success inserts on the one hand; Thereby the subscriber equipment that inserts of being used on the other hand to fail is found its access failure and is attempted access again.
Figure 13 is used to analyze the generation of the collision that non-synchronized random inserts and the example of testing mechanism.As shown in figure 13, subscriber equipment at first sends arbitrary access front signal (1301), might bump here, promptly adopts identical targeting signal to initiate simultaneously to insert at random more than a subscriber equipment.Next each possible targeting signal (1302) of network measuring, and with corresponding threshold value relatively, when the power of certain targeting signal surpassed threshold value, network thinks current had subscriber equipment to send this targeting signal.Thereby network sends accidental access response information (1303).Here, whether network can detect current certain targeting signal and be sent out, but might send identical targeting signal simultaneously by a plurality of subscriber equipmenies, network can't be distinguished this situation, that is to say network and sent response message, but might all monitor this response message by a plurality of subscriber equipmenies at certain targeting signal.After subscriber equipment has sent random access information (1301), detect the response message (1304) of network according to timing relationship, if the user does not detect the response message that sends to it, illustrate to send the random access information failure that subscriber equipment attempts initiating again random access procedure; When subscriber equipment had been received sure response message, subscriber equipment was further random access information and other information (1305) of sending on the ascending resource of its distribution at network.It should be noted that subscriber equipment detects the response message of network to the targeting signal of its transmission, can not illustrate that collision does not take place, because might all correctly receive the response message of network by a plurality of subscriber equipmenies, thereby there are a plurality of subscriber equipmenies all on identical ascending resource, to send its further information to same targeting signal.In order to distinguish the situation of a plurality of subscriber equipment competition ascending resources that may occur, in this message (1305), subscriber equipment need carry the information of its identity of sign.If subscriber equipment has sign CRNTI unique in the sub-district, subscriber equipment sends its CRNTI; If subscriber equipment does not have CRNTI, subscriber equipment need send other user ID such as its IMSI or TMSI.Next the information (1306) that sends of network measuring subscriber equipment, here network can detect the information of a subscriber equipment at the most, thereby can obtain the sign of the subscriber equipment of current transmission information, for its whether success of access operation at random of notifying user equipment, network sends response message in message 1307, comprise the user ID of the subscriber equipment that will confirm.By message 1307, whether successful network offer subscriber equipment and detect it fully and insert mechanism at random.In addition in message 1307, except the sign that sends subscriber equipment, network can also comprise other control information, and a kind of mode is the subscriber equipment that does not distribute CRNTI to current, and network can send network in this message (1307) be the CRNTI of user equipment allocation; Another mode is that network sends downlink data or uplink scheduling message in message (1307).Next subscriber equipment detects the response message (1308) of network, and here (1308), whether subscriber equipment can detect its process that sends the non-synchronized random access fully successful.When subscriber equipment is received the response message that sends to it, represent its access operation success at random; When subscriber equipment is not received the response message that sends to it, represent its access operation failure at random, subscriber equipment has to initiate again to insert at random in the suitable moment.Then subscriber equipment and network further interactive information continue to finish follow-up operation (1309).
Method of the present invention can be used for transmitting the message (1307) that Figure 13 network sends to subscriber equipment.Method of the present invention is not limited to the flow process that the non-synchronized random among Figure 13 inserts, as long as network need send the sign of subscriber equipment in its response message, the present invention just can use.Be that the user ID that sends in step 1307 is the example of the IMSI of subscriber equipment as shown in figure 14, the length of supposing CRC here is 16 bits.Here suppose network the second portion of the first digit of all numerals of the MCC of IMSI and MNC as IMSI, and the first of second bit of all numerals of MSIN and MNC as IMSI.The CRC (1401) that 16 bits are calculated in the bit that the back numeral of all numerals of MSIN among the IMSI of at first network based subscriber equipment and MNC is corresponding and other control informations; Network is done mask operation (1402) to 16 bit bits of the first digit correspondence of 3 numerals of the MCC of IMSI and MNC and the CRC that calculates then; Then, the CRC cascade composition after network is operated corresponding bit, other control information bits and the mask of a back numeral of all numerals of the MSIN among its IMSI and MNC sends block of information (1403); Next network carries out operation such as chnnel coding and sends (1404) sending block of information.The hypothesis network is the second portion of the first digit of all numerals of the MCC among the IMSI and MNC as IMSI among Figure 14, and the implicit CRC that passes through to calculate transmission, promptly do the mask operation with CRC, in fact this flow process is equally applicable to the situation that network is other 16 bits of IMSI and CRC the mask operation.
Similar with Figure 14, Figure 15 is that the user ID that sends in step 1307 when network is the example of the TMSI of subscriber equipment, here the length of supposing TMSI is 32 bits, the length of CRC is 16 bits, here suppose that network is divided into its second portion to 16 bits among the TMSI, thereby do mask operation with CRC, the present invention not limiting network any 16 bits among the TMSI as its second portion, other 16 bits of TMSI are its first.As shown in figure 15, at first network based TMSI 16 bits and other control informations of first calculate CRC (1501); Then network TMSI 16 bits of second portion and the CRC that calculates do mask operation (1502); Then, network TMSI 16 bits, other control informations of first and the CRC cascade after the mask operation form and send block of information (1503); Next network carries out operation such as chnnel coding and sends (1504) sending block of information.
Figure 16 is that the user ID that sends in step 1307 is another example of the TMSI of subscriber equipment, here suppose that network calculates the odd bit of 1 bit to the TMSI of subscriber equipment, and suppose here network preceding 16 bits of TMSI as its first, back 16 bits are as its second portion.As shown in figure 16, network at first calculates odd bit (1601) according to the TMSI of subscriber equipment; Calculate the odd bit then in preceding 16 bits of network based TMSI, other control bits, the step 1001 and calculate CRC (1602); Then network is done mask operation (1603) to back 16 bits of TMSI with the CRC that calculates; Transmission block of information (1604) is formed in the CRC cascade after thereby network is operated preceding 16 bits of TMSI, other control bits, odd bit and mask; Next network carries out operation such as chnnel coding and sends (1605) sending block of information.
