Detailed Description
In order to improve the generation efficiency of the identification information of the IM message on the premise of ensuring global uniqueness, in the embodiment of the present disclosure, a corresponding target timestamp, a target IMEI, and a target complement bit code are obtained based on an initial IM identification in the IM message reported by a user terminal, and a global unique identification corresponding to the IM message is generated based on the target timestamp, the target IMEI, and the target complement bit code.
Preferred embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 2, in the embodiment of the present disclosure, a detailed flow of the IM server generating the globally unique identifier for the IM message is as follows:
step 200: the IM server receives an IM message sent by a user terminal, wherein the IM message at least carries an initial IM identifier.
Specifically, the initial IM identifier at least includes: sign bit, first timestamp, first IMEI and first complement bit code.
Further, the sign bit occupies 1bit, and since the globally unique identifier is necessarily a positive number, the sign bit is always 0.
The time stamp is 41 bits, the unit of time is milliseconds, and the time stamp can theoretically identify 69 years of time.
The IMEI occupies 15 bits, and if the user terminal is a mobile terminal, the IMEI value range is any integer from binary numbers 111111111111111 to 000000000000001. If the user terminal is a non-mobile terminal, the IMEI is 000000000000000.
The complement code occupies 7 bits, the complement code is used for distinguishing IM messages generated corresponding to the same IMEI in the same time unit, the value range is any integer of 1111111 to 0000000 binary numbers, and 128 values are provided.
In the embodiment of the present disclosure, the bit complementing codes are set corresponding to the timestamp + the IMEI, so that the same "timestamp + IMEI" may correspond to 128 bit complementing codes at most, and thus, the IM messages generated corresponding to the same IMEI in the same time unit may be distinguished.
For example: assuming that the first timestamp is 000000000000000000000000000000000000000001 (hereinafter, 00 … … 01 is substituted), the corresponding first IMEI is 000000000000001, and the first timestamp and the first IMEI are combined to generate 4 first padding codes and are combined to different initial IM identities, respectively:
1. 0 (sign bit) 00 … … 01 (time stamp) 000000000000001 (IMEI) 0000000 (complement bit code);
2、0 00……01 000 000 000 000 001 000 000 1；
3、0 00……01 000 000 000 000 001 000 001 0；
4、0 00……01 000 000 000 000 001000 001 1。
further, if the IMEI is updated, the total number of the complementary bit codes generated corresponding to the "timestamp + IMEI" is cleared, that is, the generation of 128 new complementary bit codes needs to be restarted.
For example, under the same timestamp, a new mobile terminal sends an IM message, a new first IMEI is generated, and assuming that the generated new first IMEI is 000000000000010, although the first complementary codes under IMEI 00000000001 have been accumulated to 0000011, after the first IMEI is updated, the first complementary codes are recalculated from 0000000, and assuming that 5 new first complementary codes are generated corresponding to the first timestamp and the new first IMEI, and are combined into different initial IM identifiers, respectively:
1、0 00……01 000 000 000 000 010 000 000 0；
2、0 00……01 000 000 000 000 010 000 0001；
3、0 00……01 000 000 000 000 010 000 0010；
4、0 00……01 000 000 000 000 010 000 0011；
5、0 00……01 000 000 000 000 010 000 010 0。
on the other hand, if the timestamp is updated, the total number of the complementary codes generated corresponding to the "timestamp + IMEI" is cleared, that is, it is necessary to restart generation of new 128 complementary codes.
For example, as the time stamp is updated to the next millisecond, a new first time stamp 00 … … 10 is generated, the corresponding first IMEI is still 000000000000001, although the first complementary bit code at the time stamp 00 … … 01 has been accumulated to 0000011, after the first time stamp is updated, the first complementary bit code is calculated from 0000000 again, and it is assumed that 3 new first complementary bit codes are generated corresponding to the new first time stamp and the IMEI combination and are combined into different initial IM identifications respectively, which are:
1、0 00……10 000 000 000 000 001000 000 0；
2、0 00……10 000 000 000 000 001000 001 0；
3、0 00……10 000 000 000 000 001000 001 1；
step 210: and the IM server obtains a target timestamp, a target IMEI and a target carry code corresponding to the IM message based on the initial IM identification.
Specifically, when step 210 is executed, the following two cases are included but not limited to:
case 1: the value of the IMEI information bit contained in the initial IM identification is not zero.
In this case, it is described that the mobile terminal sends the IM message to the IM server, and the IMEI in the initial IM identifier carried in the IM message, that is, the IMEI used by the mobile terminal itself, in this case, the IM server will directly read, from the IM message, the first timestamp, the first IMEI, and the first padding code carried in the IM message by the user terminal, as the target timestamp, the target IMEI, and the target padding code corresponding to the IM message.
For example, assume that there are two mobile terminals generating IM messages carrying initial IM identifiers respectively:
1、0 00……01 000 000 000 000 001 000 010 1；
2、0 00……10 000 000 000 000 010 000 0010。
when the IM server receives the IM identifier and the value of IMEI information bit contained in the initial IM identifier is not zero, directly obtaining a target timestamp 00 … … 01, a target IMEI 00000000001 and a target complement bit code 0000101 based on a first timestamp, a first IMEI and a first complement bit code in the first initial IM identifier; meanwhile, the IM server directly obtains a target timestamp 00 … … 10, a target IMEI 00000000010 and a target complement code 0000010 based on the first timestamp, the first IMEI and the first complement code in the second initial IM identifier.
Therefore, when the IMEI code is not zero, the corresponding global unique identifier can be quickly generated.
Case 2: the IMEI information bit contained in the initial IM identification takes a value of zero.
In this case, it is described that a non-mobile terminal that sends an IM message to an IM server is used, and an initial IM identifier carried in the IM message does not carry an IMEI, and it is necessary for the IM server to reselect one historical IMEI that meets a preset condition from among used historical IMEIs reported by other mobile terminals, and obtain a second timestamp corresponding to the historical IMEI, and when a total number of historical padding codes that have been set corresponding to the second timestamp and the historical IMEI does not reach a preset threshold value, generate a new padding code corresponding to the second timestamp and the history, and use the second timestamp as a target timestamp, use the selected historical IMEI as a target IMEI, and use the new padding code as a target padding code.
In this way, even if the non-mobile terminal does not have an IMEI, the IM message sent by the non-mobile terminal may also have a globally unique identity.
Further, when selecting a historical IMEI meeting the preset condition, the method includes, but is not limited to, any one of the following methods:
the method comprises the following steps: and selecting the historical IMEI with the shortest duration between the corresponding second timestamp and the current time from the used historical IMEIs to serve as the historical IMEI meeting the preset condition.
For example, assume that an initial IM identifier carried in an IM message generated by a non-mobile terminal is:
000……100 000 000 000 000 000 000 000 0。
because the IMEI information bit value in the initial IM identifier is zero, each used historical IMEI needs to be acquired, and assuming that three historical IMEIs are acquired, the IMEI information bits are respectively:
000000000000001, the corresponding second timestamp is: 00 … … 01, the number of generated complement codes corresponding to 000000000000001 +00 … … 01 is 3;
000000000000010, the corresponding second timestamp is: 00 … … 10, the number of generated complement codes corresponding to 000000000000010 +00 … … 10 is 4;
000000000000011, the corresponding second timestamp is: 00 … … 11, the number of generated complement codes corresponding to 000000000000011 +00 … … 11 is 5;
since 000000000000011 is the shortest time from the current time, 000000000000011 is selected as a historical IMEI meeting the predetermined condition.
After selecting 000000000000011, it is further determined whether the number of complementary codes generated corresponding to 000000000000011 +00 … … 11 reaches 128? Since the number of generated complementary bit codes corresponding to "000000000000011 +00 … … 11" is 5, obviously, 128 is not reached, the generation of new complementary bit codes corresponding to "000000000000011 +00 … … 11" can be continued, assuming that the newly generated complementary bit codes are 0000101.
Finally 00000000000011 is taken as the target IMEI, the second timestamp 00 … … 11 is taken as the target timestamp, and the newly generated complement code 0000101 is taken as the target complement code.
The second method comprises the following steps: acquiring a preset hash data set, wherein identification information of one hash data is a hash value obtained after a historical IMEI is subjected to hash function processing, and a value representation of the one hash data represents a total number of generated complement numbers corresponding to the historical IMEI and a corresponding second timestamp; and selecting the historical IMEI corresponding to the minimum value from the values of the hash data as the historical IMEI meeting the preset condition.
For example, assume that an initial IM identifier carried in an IM message generated by a non-mobile terminal is:
0 00……10 000 000 000 000 000 000 000 0。
because the IMEI information bit value in the initial IM identifier is zero, a preset hash data set is obtained, for example: {2,5,9,45,66,23,77}.
In the hash data set, the identification information of one hash data is a hash value obtained by processing a historical IMEI through a hash function, and the value representation of the one hash data represents the total number of the generated bit-complementing codes corresponding to the historical IMEI and the corresponding second timestamp; optionally, in the embodiment of the present disclosure, in the values of each hash data, a historical IMEI corresponding to the minimum value is selected as one historical IMEI meeting the preset condition.
Because the value of each hash data in the hash data set is equal to the total number of the generated bit complementing codes corresponding to each historical IMEI and the corresponding second timestamp. Then, the hash data with the value of 2 represents that the total number of the generated bit-complementing codes corresponding to one historical IMEI and the corresponding second timestamp is 2; and the hash data with the value of 5 represents that the total number of the generated bit complementing codes corresponding to one historical IMEI and the corresponding second timestamp is 5, and so on.
Based on the rule, if the minimum value is 2 in the values of the hash data, the historical IMEI represented by the hash value corresponding to the minimum value 2 is finally selected as the historical IMEI meeting the preset condition; assuming the historical IMEI is: 000000000000111, and assuming that the historical IMEI corresponds to a second timestamp of: 00 … … 01.
Further, it is necessary to determine whether the number of generated complementary bit codes corresponding to "000000000000111 +00 … … 01" reaches 128? Since the number of generated complementary bit codes corresponding to "000000000000111 +00 … … 01" is 2, obviously, 128 is not reached, that is, the history IMEI is not used up, then, new complementary bit codes corresponding to "000000000000111 +00 … … 01" can be continuously generated, and the newly generated complementary bit codes are assumed to be 0000010.
Finally, 000000000000111 is set as the target IMEI, the second timestamp 00 … … 01 is set as the target timestamp, and the newly generated complementary bit code 0000010 is set as the target complementary bit code.
Thus, even if the non-mobile terminal does not have the IMEI, the appropriate IMEI can be selected from the historical IMEIs, and the corresponding global unique identifier can be generated. By the method, the problem that the non-mobile terminal has no corresponding IMEI can be solved, and the IM message sent by the non-mobile terminal also has a global unique identifier.
Step 220: and the IM server generates a global unique identifier corresponding to the IM message based on the target timestamp, the target IMEI and the target bit complementing code.
Specifically, the following two cases are classified:
for the above case 1, when step 220 is executed, the IM server may directly use the first timestamp, the first IMEI, and the first complement code as the target timestamp, the target IMEI, and the target complement code, perform global uniqueness verification on the initial IM identifier based on the target timestamp, the target IMEI, and the target complement code, and use the initial IM identifier as the global unique identifier corresponding to the IM message when the verification is passed.
On the other hand, assuming that the initial IM identifier does not pass the global uniqueness verification, the IM server may update the target bit complementing code to obtain an updated initial IM identifier, and then, the IM server may perform the global uniqueness verification on the initial IM identifier again based on the target timestamp, the target IMEI, and the updated target bit complementing code, and when the verification passes, take the updated initial IM identifier as the global uniqueness identifier corresponding to the IM message.
Therefore, when the global unique identifier which is the same as the initial IM identifier exists, the uniqueness of the global unique identifier can be ensured through the updating transformation of the complementary bit code. Especially, for a plurality of IM messages sent by the same device at the same time, a plurality of globally unique identifications with uniqueness can be generated by more effectively corresponding to each IM message.
For example, assume that the initial IM identifiers carried in the IM messages generated by the two mobile terminals are respectively:
1. 000 … … 010000000000000010000101 corresponds to the first mobile terminal;
2. 000 … … 100000000000000100000010 corresponds to the second mobile terminal.
Assume that 000 … … 010000000000000010000101 is included in the generated historical globally unique identifiers set, while assume that the generated historical globally unique identifiers set does not include 000 … … 100000000000000100000010 and 000 … … 010000000000000010000110.
It is clear that 000 … … 100000000000000100000010 may directly serve as the globally unique identification of the second mobile terminal. And after finding that 000 … … 010000000000000010000101 exists, the IM server updates the complementary bit code in 000 … … 010000000000000010000101 to obtain 000 … … 010000000000000010000110, and after determining that 000 … … 010000000000000010000110 does not exist, the IM server takes 000 … … 010000000000000010000110 as the global unique identifier of the first mobile terminal.
For the above case 2, when executing step 220, the IM server uses the second timestamp as a target timestamp, uses the selected historical IMEI as a target IMEI, uses the new complement code as a target complement code, and generates a globally unique identifier corresponding to the IM message based on the target timestamp, the target IMEI, and the target complement code.
Since the target timestamp, the target IMEI and the target complement code are regenerated by the IM server, the target timestamp, the target IMEI and the target complement code must have global uniqueness, and the global unique identifier corresponding to the IM message can be directly generated without verifying the global uniqueness.
For example, assuming that the target timestamp generated by the system is 00 … … 01, the target IMEI is 000000000000111, and the target complement code is 0000010, the globally unique identifier can be directly generated as:
0 00……01000 000 000 000 111000 0010。
the above embodiments are further described in detail below using three specific application scenarios.
Scene one: and the mobile terminal sends the IM message and generates a global unique identifier corresponding to the IM message.
Referring to fig. 3, it is assumed that the mobile terminal edits two IM messages, which are respectively referred to as a first IM message and a second IM message, and the initial IM identifiers carried by the two IM messages are respectively referred to as an initial IM identifier 1 and an initial IM identifier 2.
After the mobile terminal finishes editing the two IM messages, the mobile terminal sends the two IM messages at the same time, because the two IM messages are sent at the same time, the timestamps in the initial IM identifier 1 and the initial IM identifier 2 are the same, and the two IM messages are both assumed to be 00 … … 11, and because the two IM messages are sent by the same mobile terminal, the values of the IMEI information bits in the initial IM identifier 1 and the initial IM identifier 2 are both not zero and the same, and the assumptions are both: 000000000001000, further, in order to distinguish the two IM messages, the complement code in the initial IM id 1 is 0000001, and the complement code in the initial IM id 2 is 0000010; as can be seen, the initial IM id 1 and the initial IM id 2 can be respectively expressed as:
initial IM identification 1: 000 … … 110000000000010000000001;
initial IM identification 2: 000 … … 110000000000010000000011.
Assuming that the generated historical global unique identifier set is as follows:
{0 00……11 000 000 000 001000 000 000 0；
0 00……11 000 000 000 001000 000 000 1}。
the IM server directly obtains a target timestamp 00 … … 11, a target IMEI 000000000001000 and a target complement bit code 0000001 based on the initial IM identifier 1, and performs global uniqueness verification on the initial IM identifier 1 at the same time to find that the same global unique identifier already exists, so that the target complement bit code is updated to 0000010, forms a new IM identifier with the target timestamp and the target IMEI, performs global uniqueness verification again, and at this time, after verification passes, generates a global unique identifier corresponding to the first IM message:
0 00……11 000 000 000 001000 000 001 0。
at this time, the generated history global unique identifier set is updated as follows:
{0 00……11 000 000 000 001000 000 000 0；
0 00……11 000 000 000 001000 000 000 1；
0 00……11 000 000 000 001000 000 001 0}。
the IM server directly obtains a target timestamp 00 … … 11, a target IMEI 000000000001000, and a target complementary bit code 0000011 based on the initial IM identifier 2, and performs global uniqueness verification on the initial IM identifier 2, and generates a global unique identifier corresponding to the second IM message after the verification is passed:
0 00……11 000 000 000 001000 000 001 1。
at this time, the generated history global unique identifier set is updated as follows:
{0 00……11 000 000 000 001000 000 000 0；
0 00……11 000 000 000 001000 000 000 1；
000……11 000 000 000 001000 000 001 0；
0 00……11 000 000 000 001000 000 001 1}。
scene two: and the non-mobile terminal sends IM messages, selects the history IMEI with the shortest duration between the corresponding second timestamp and the current time from the used history IMEIs to serve as an IMEI method according with the preset condition, generates corresponding target timestamps and target IMEI target position-supplementing codes based on the history IMEIs, and further generates a global unique identifier corresponding to the IM messages.
Referring to fig. 4, it is assumed that a non-mobile terminal sends an IM message, and the initial IM identifier carried in the IM message is:
0 00……100 000 000 000 000000 000 000 0。
assuming that the generated historical global unique identifier set is as follows:
{0 00……01 000 000 000 001001 000 000 0；
0 00……10 000 000 000 001010 000 000 0；
0 00……10000 000 000 001010 000 000 1；
0 00……11 000 000 000 001010 000 001 0；
000 … … 110000000000011001111111 (this globally unique identifier indicates that the complement code corresponding to "00 … … 11+ 000000000001100" has been exhausted, but was not written out of the set due to the excess).
Because the duration between the second timestamp corresponding to 000000000001100 and the current time is the shortest, 000000000001100 is selected as a historical IMEI meeting the preset condition, but the IM server further determines and learns that the complementary bit codes corresponding to the second timestamp and the historical IMEI are used up, and therefore, a new historical IMEI is searched again, where the complementary bit codes corresponding to the second timestamp are not used up; therefore, 000000000001010 is selected as a new history IMEI meeting the preset condition, and the IM server finds, by determining, that the complementary codes corresponding to the second timestamp and the new history IMEI are not used up, and further generates a corresponding second complementary code 0000011. Therefore, 000000000001010 is selected as the target IMEI, 00 … … 10 is selected as the target timestamp, and 0000011 is selected as the target complement code.
Since the target timestamp, the target IMEI, and the target carry code are generated by the IM server, and therefore must have uniqueness, the IM server generates the globally unique identifier corresponding to the IM message based on the target timestamp, the target IMEI, and the target carry code:
000……10 000 000 000 001010 000 001 1。
and updating the generated historical global unique identification set.
Scene three: and the non-mobile terminal sends IM messages, selects the historical IMEI corresponding to the minimum value from the values of the hash data as a historical IMEI method meeting the preset conditions, generates corresponding target time stamps and target IMEI target bit supplementing codes based on the historical IMEI, and further generates a global unique identifier corresponding to the IM messages.
Referring to fig. 5, it is assumed that a non-mobile terminal sends an IM message, and the initial IM identifier carried in the IM message is:
0 00……101 000 000 000 000000 000 000 0。
assuming that the preset hash data set is: {1,3,5,7,11,13,17}.
Assuming the value of each hash data in the hash data set, representing the total number of the generated bit-complementing codes corresponding to each historical IMEI and the corresponding second timestamp; namely, the hash data with the value of 1 represents that the total number of the generated bit complementing codes corresponding to one history IMEI and the corresponding second timestamp is 1; and the hash data with the value of 3 represents that the total number of the generated bit complementing codes corresponding to one historical IMEI and the corresponding second timestamp is 3, and so on.
The IM server selects the values of the hash data, takes the historical IMEI represented by the hash value corresponding to the minimum value 1, and assumes the historical IMEI as one historical IMEI meeting the preset conditions; assuming the historical IMEI is: 000000000001111, and assuming that the historical IMEI corresponds to a second timestamp of: 00 … … 111.
Further, it is necessary to determine whether the number of complementary bit codes generated corresponding to "000000000001111 +00 … … 111" reaches 128? Since the number of generated complementary bit codes corresponding to "000000000001111 +00 … … 111" is 1, obviously, 128 is not reached, that is, the above history IMEI is not used up, then, new complementary bit codes corresponding to "000000000001111 +00 … … 111" can be continuously generated, assuming that the newly generated complementary bit codes are 0000001.
Finally 000000000001111 is taken as the target IMEI, the second timestamp 00 … … 111 is taken as the target timestamp, and the newly generated complementary bit code 0000001 is taken as the target complementary bit code.
Since the target timestamp, the target IMEI, and the target carry code are generated by the IM server, and therefore must have uniqueness, the IM server generates the globally unique identifier corresponding to the IM message based on the target timestamp, the target IMEI, and the target carry code:
0 00……111 000 000 000 001111 000 000 1。
and updating the preset hash data set.
