Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
Example one
Fig. 1 is a flowchart of a synchronization method for a cloud address book service according to an embodiment of the present invention, where the method is applicable to a situation of synchronizing an address book on a terminal and a cloud end, and the method may be executed by a synchronization device for the cloud address book service, and the synchronization device for the cloud address book service may be configured in a cloud end server, and specifically includes the following steps:
s110, according to a synchronization request sent by a terminal, determining cloud updating data of a cloud address book after the terminal is synchronized last time.
In the embodiment of the invention, the address book is respectively stored in the terminal and the cloud server. For a certain user, the user may have multiple terminals, and the respective terminal address lists are stored in the different terminals, and the contents of the terminal address lists may be inconsistent, for example, the user may store the communication mode of Zhang III of a friend on a mobile phone A, but does not store the communication mode of the friend on a mobile phone B. The cloud server provides a cloud address book for the user, and uniformly stores synchronous communication information uploaded by the user through each terminal to serve as the cloud address book. And the cloud server can distinguish the entries of the terminal address lists corresponding to the terminals in the cloud address list through the terminal identifications.
When the user synchronizes communication data to the cloud server through each terminal so that the cloud address book is updated, the cloud update data (sx _ list) can be stored in the cloud update list. The cloud updating data refers to data generated by updating the cloud address book, and comprises data adding, data modifying and data deleting. For example, a communication mode with Zhang III added is uploaded by the mobile phone A, namely, the communication mode is a piece of cloud updating data, and the cloud updating data is correspondingly stored in a cloud updating list. When the terminal needs to synchronize the terminal address book and the cloud address book, the terminal sends a synchronization request to the cloud server, and the synchronization request can indicate the end position of cloud update data generated when the terminal is synchronized with the cloud address book last time in the cloud update list, so that the start position of the cloud update data of the cloud address book in the cloud update list after the terminal is synchronized with the cloud address book last time is also indicated. And the positions of each terminal for synchronous updating can be independently recorded in the cloud updating list. The embodiment will illustrate the technical solution from the perspective of requesting synchronization from a terminal to a cloud server.
After receiving a synchronization request sent by a terminal, a cloud server determines the cloud update data of a cloud address book after last synchronization with the terminal according to the initial position of the cloud update data of the cloud address book in a cloud update list after the terminal in the synchronization request is synchronized with the cloud address book last time, and writes the cloud update data of the cloud address book after last synchronization with the terminal into a cache.
And S120, determining terminal updating data of the terminal address book according to the terminal address book identification sent by the terminal.
The terminal address book identification is obtained by calculating the terminal address book data through a preset algorithm, and can be used for distinguishing the address book data of each terminal by representing more terminal address book data with less data information.
After the terminal address book and the cloud address book are synchronized last time, the data of the terminal address book and the data of the cloud address book are consistent, and therefore the terminal address book identification stored in the cloud end and the terminal address book identification stored in the terminal are also the same. And if the terminal address book has data to be updated after the last synchronization, the terminal address book identification stored in the terminal changes relative to the terminal address book identification synchronized last time, and the terminal address book identification stored in the cloud end is not updated. Therefore, the terminal address book identifier sent by the terminal is the latest identifier, and the terminal address book identifier is compared with the terminal address book identifier stored in the cloud, so that the terminal update data (cx _ list) of the terminal address book can be determined after the last synchronization. By comparing the terminal address book identification, the data to be updated can be determined by comparing with less data volume without transmitting and comparing all address book data.
And S130, performing conflict processing on the cloud updating data and the terminal updating data, and determining cloud synchronous updating data to be updated in the cloud address book and terminal synchronous updating data to be updated in the terminal address book.
After the last synchronization, the cloud address book and the terminal address book are updated respectively, and cloud update data and terminal update data are generated. If the cloud updating data and the terminal updating data are updating data for different contacts, the updating data of the opposite terminal can be updated according to the updating data of one terminal. If the cloud updating data and the terminal updating data are updating data for the same contact person, the updating data comprise adding data, modifying data and deleting data, and the two updating data (the cloud updating data and the terminal updating data) perform different updating operations on the same contact person, the two updating data conflict with each other and need to be subjected to conflict processing; if the two update data carry out the same update operation on the same contact person, the address book entries aiming at the contact person in the cloud address book and the terminal address book do not need to be updated. Therefore, the cloud synchronous updating data to be updated in the cloud address book and the terminal synchronous updating data to be updated in the terminal address book can be determined.
And S140, updating the cloud address book according to the cloud synchronous updating data, and sending the terminal synchronous updating data to the terminal so as to update the terminal address book of the terminal.
And updating the cloud synchronous updating data into a cloud address book, issuing the terminal synchronous updating data to the terminal, and updating the terminal synchronous updating data into the terminal address book by the terminal. And after the terminal updates the terminal address book, updating the terminal address book identification according to the updated terminal address book.
The step of sending the terminal synchronous update data to the terminal to update the terminal address list of the terminal comprises the following steps:
paging and writing the terminal synchronous updating data into a cache;
and gradually issuing the terminal synchronous updating data stored in the cache in a paging manner to the terminal.
When the data volume of the terminal synchronous updating data is large, the terminal synchronous updating data can be written into the cache in a paging mode, and after the terminal request is received, the terminal synchronous updating data stored in the cache in a paging mode are issued to the terminal one by one, so that overtime of a single request is prevented.
In the technical scheme of this embodiment, the cloud update data of the cloud address book after the terminal is synchronized last time is determined according to the synchronization request sent by the terminal, and determines the terminal update data of the terminal address book according to the terminal address book identification sent by the terminal, conflict processing is carried out on the cloud updating data and the terminal updating data, cloud synchronous updating data to be updated in a cloud address book and terminal synchronous updating data to be updated in a terminal address book are determined, thereby updating the cloud address book according to the cloud synchronous updating data and sending the terminal synchronous updating data to the terminal, the terminal address book of the terminal is updated, conflict processing is carried out on the cloud server, and the cloud synchronous updating data and the terminal synchronous updating data are determined.
Example two
Fig. 2 is a flowchart of a synchronization method for an address book cloud service according to a second embodiment of the present invention, and in this embodiment, based on the first embodiment, the "determining terminal update data of a terminal address book according to a terminal address book identifier sent by a terminal" is further optimized to "receiving a total data identifier (total _ md5) of the terminal address book sent by the terminal, where the total data identifier is an overall identifier of all address book data in the terminal address book; comparing the received full data identification with the full data identification stored in the cloud; and determining terminal update data of the terminal address list according to the comparison result. The method specifically comprises the following steps:
s210, according to a synchronization request sent by a terminal, determining cloud updating data of a cloud address book after the terminal is synchronized last time.
And S220, receiving a full data identifier of the terminal address book sent by the terminal, wherein the full data identifier is an integral identifier of all address book data in the terminal address book.
After the terminal address book is updated, the corresponding terminal address book identification is also updated, the terminal address book identification comprises a full data identification, and the full data identification is an integral identification of all address book data in the terminal address book and can be represented by a character string. When the terminal address book is synchronized with the terminal address book, the terminal sends the full data identification of the terminal address book to the cloud server, so that the cloud server can compare the full data identification with the full data identification of the terminal stored in the cloud, and the terminal update data of the terminal address book is determined after last synchronization.
And S230, comparing the received full data identification with the full data identification stored in the cloud.
The full data identification stored in the cloud is the full data identification of the terminal address book of the terminal formed when the terminal is synchronized with the cloud last time.
And comparing the received full data identification with the full data identification stored in the cloud end to determine whether the received full data identification is consistent with the full data identification stored in the cloud end.
And S240, determining terminal updating data of the terminal address list according to the comparison result.
If the terminal address list is consistent with the terminal address list, determining that the terminal address list is not updated after the last synchronization; and if not, determining that the address book of the terminal is updated after the last synchronization. The terminal update data of the terminal address book can be determined by comparing the terminal address book with the cloud address book synchronized last time. After last synchronization, the cloud server can store the cloud address book in last synchronization, and the cloud address book in last synchronization is consistent with the terminal address book data.
Fig. 3 is a flowchart of determining terminal update data of a terminal address book in the synchronization method for the address book cloud service according to the embodiment of the present invention. As shown in fig. 3, determining the terminal update data of the terminal address book according to the comparison result preferably includes:
s241, if the received full data identification is inconsistent with the full data identification stored in the cloud, indicating the terminal to send an item identification list of the terminal address book;
the item identification list (full _ md5) is a single identification of each item of address book data in the terminal address book, and the single identification is a character string representing an item main key (lid) and an item identification (raw _ md5) of the single item of address book data. The entry main key is the serial number of the single address book data, and the entry identification is the actual single address book data.
S242, comparing the received item identification list with an item identification list stored in a cloud end;
the entry identification list stored in the cloud is an entry identification list of a terminal address book of the terminal formed in last synchronization.
S243, if the received entry identification list is inconsistent with the entry identification list stored in the cloud, determining an added entry identification list and a deleted entry identification list of the terminal address book;
if the received entry identifier list is inconsistent with the entry identifier list stored in the cloud, a single identifier in the received entry identifier list does not exist in the entry identifier list stored in the cloud, or a single identifier in the entry identifier list stored in the cloud does not exist in the received entry identifier list. At this time, a list consisting of single identifiers which exist in the received entry identifier list and do not exist in the entry identifier list stored in the cloud is determined as an added entry identifier list of the terminal address book, and a list consisting of single identifiers which exist in the entry identifier list stored in the cloud and do not exist in the entry identifier list stored in the cloud is determined as a deleted entry identifier list of the terminal address book.
And S244, determining the terminal updating data of the terminal address list according to the added item identification list and the deleted item identification list.
The terminal address book entry represented by the added entry identifier list can be determined as added data in the terminal update data of the terminal address book, and the cloud address book entry represented by the deleted entry identifier list can be determined as deleted data in the terminal update data.
The received item identification list and the item identification list stored in the cloud are compared to determine the terminal updating data of the terminal address list, so that the comparison time can be further reduced, and the synchronization time is further reduced.
And S250, performing conflict processing on the cloud updating data and the terminal updating data, and determining cloud synchronous updating data to be updated in the cloud address book and terminal synchronous updating data to be updated in the terminal address book.
And S260, updating the cloud address book according to the cloud synchronous updating data, and sending the terminal synchronous updating data to the terminal so as to update the terminal address book of the terminal.
According to the technical scheme, on the basis of the first embodiment, whether the terminal address book is updated or not can be directly determined by comparing the full data identification of the terminal address book sent by the terminal with the full data identification stored in the cloud, and when the terminal address book is not updated, the synchronization time can be further shortened.
On the basis of the above technical solution, determining that the terminal update data (cx _ list) of the terminal address book preferably includes, according to the added entry identifier list (full _ md5) and the deleted entry identifier list (full _ md 5):
instructing the terminal to transmit an item identification (raw _ md5) and an item primary key (lid) corresponding to the added item identification list (full _ md 5);
acquiring an item identifier (raw _ md5) and an item primary key (lid) corresponding to the deleted item identifier list (full _ md5) stored in the cloud;
comparing the newly added entry identifier (raw _ md5) with the deleted entry identifier (raw _ md5), and comparing the entry primary key (lid) corresponding to the newly added entry identifier (raw _ md5) with the entry primary key (lid) corresponding to the deleted entry identifier (raw _ md 5);
if the newly added item identification (raw _ md5) is consistent with the deleted item identification (raw _ md5), and the item primary key (lid) corresponding to the newly added item identification (raw _ md5) is inconsistent with the item primary key (lid) corresponding to the deleted item identification (raw _ md5), updating the deleted item primary key (lid) with the newly added item primary key (lid); for example, if the entry primary key for the communication method corresponding to the third page in the added entry identifier list is 25, and the entry primary key for the communication method corresponding to the same third page in the deleted entry identifier list is 22, the 22 is updated to 25.
And if the newly added entry identifier (raw _ md5) is inconsistent with the deleted entry identifier (raw _ md5), determining terminal update data (cx _ list) according to the terminal address book entry corresponding to the newly added entry identifier (raw _ md5) and the cloud address book entry corresponding to the deleted entry identifier (raw _ md 5). For example, if the mobile phone number of zhang san corresponding to the newly added entry identifier is 13901001100, and each deleted entry identifier is inconsistent with the newly added entry identifier, the mobile phone number of zhang san 13901001100 may be determined as the terminal added data in the terminal update data; the cell phone number of the prune four corresponding to the deleted entry identifier is 13812345678, and each of the newly added entry identifiers is inconsistent with the deleted entry identifier, the cell phone number of the prune four 13812345678 may be determined as the terminal deletion data in the terminal update data.
The added entry identification refers to an entry identification which is sent by a terminal and corresponds to the added entry identification list, and the deleted entry identification refers to an entry identification which is stored in a cloud and corresponds to the deleted entry identification list. If the newly added entry identifier is consistent with the deleted entry identifier, and the entry main key corresponding to the newly added entry identifier is inconsistent with the entry main key corresponding to the deleted entry identifier, it is indicated that the actual data of the terminal address book is not changed, but only the entry main key is changed (such as the change of the entry main key in the terminal address book caused by the synchronization of the address book by software such as google synchronization or crayon synchronization). If the newly added item identification is inconsistent with the deleted item identification, the actual data of the terminal address book is updated, so that the terminal update data can be determined according to the terminal address book item corresponding to the newly added item identification and the cloud address book item corresponding to the deleted item identification. The synchronization time can be further reduced by comparing the added entry identifier with the deleted entry identifier and the entry primary key corresponding to the added entry identifier with the entry primary key corresponding to the deleted entry identifier.
On the basis of the above technical solution, determining that the terminal update data (cx _ list) preferably includes, according to the terminal address book entry corresponding to the newly added entry identifier (raw _ md5) and the cloud address book entry corresponding to the deleted entry identifier (raw _ md 5):
comparing the item primary key (lid) corresponding to the newly added item identifier (raw _ md5) and the deleted item identifier (raw _ md 5);
if the entry main key (lid) corresponding to each of the newly added entry identifier (raw _ md5) and the deleted entry identifier (raw _ md5) is inconsistent, determining the terminal address book entry corresponding to the newly added entry identifier (raw _ md5) as terminal added data (ca _ list) in the terminal update data (cx _ list), and determining the cloud address book entry corresponding to the deleted entry identifier (raw _ md5) as terminal deleted data (cd _ list) in the terminal update data (cx _ list); for example, the terminal address book entry corresponding to the newly added entry identifier is a communication mode of three, the corresponding entry main key is 155, the cloud address book entry corresponding to the deleted entry identifier is a communication mode of lee four, and the corresponding entry main key is 75, it is determined that the terminal newly added the communication mode of three, but the communication mode of lee four is deleted, and the cloud address book still retains the communication mode of lee four because the cloud address book is not synchronized with the cloud.
And if the entry main key (lid) corresponding to the newly added entry identifier (raw _ md5) and the deletion entry identifier (raw _ md5) are consistent, determining the address book entry corresponding to the newly added entry identifier (raw _ md5) and the deletion entry identifier (raw _ md5) as the terminal modification data (cu _ list) in the terminal update data (cx _ list). For example, if the terminal address book entry corresponding to the newly added entry identifier is zhang and the corresponding mobile phone number is 13901001100, the entry primary key corresponding to the newly added entry identifier is 22, the cloud address book entry corresponding to the deleted entry identifier is zhang and the corresponding mobile phone number is 13812345678, and the entry primary key corresponding to the deleted entry identifier is 22, it is determined that the terminal modifies the mobile phone number of zhang from 13812345678 to 13901001100.
And when the newly added item identification is inconsistent with the deleted item identification, the terminal added data, the terminal deleted data and the terminal modified data in the terminal updated data of the terminal address book are determined by further comparing the item main keys corresponding to the newly added item identification and the deleted item identification. By positioning and updating data at the cloud, development difficulty is reduced, processing speed is increased, and synchronization time is further reduced.
EXAMPLE III
Fig. 4 is a flowchart of a synchronization method for a cloud service of an address book according to a third embodiment of the present invention, where in this embodiment, "conflict processing is performed on the cloud update data and the terminal update data, and determination is made on the cloud synchronization update data to be updated in the cloud address book and the terminal synchronization update data to be updated in the terminal address book" is further optimized to "determine update data for different contacts and update data for the same contact in the cloud update data and the terminal update data according to the cloud update data and the terminal update data; performing conflict processing on the update data aiming at the same contact in the cloud update data and the terminal update data, and determining cloud part data aiming at the cloud synchronous update data of the same contact and terminal part data of the terminal synchronous update data; and determining synchronous cloud updating data according to the updating data of different contacts in the terminal updating data and the cloud part data, and determining synchronous terminal updating data according to the updating data of different contacts in the cloud updating data and the terminal part data. The method specifically comprises the following steps:
s410, according to a synchronization request sent by a terminal, determining that the cloud end of the cloud end address list updates data after the terminal is synchronized last time.
And S420, determining terminal updating data of the terminal address book according to the terminal address book identification sent by the terminal.
S430, according to the cloud updating data and the terminal updating data, determining updating data aiming at different contacts and updating data aiming at the same contact in the cloud updating data and the terminal updating data.
When conflict processing is carried out, only the conflict processing needs to be carried out on the update data of the same contact person in the cloud end update data and the update data of the same contact person in the terminal update data, so that the cloud end update data and the terminal update data need to be compared to determine the update data of different contact persons and the update data of the same contact person in the cloud end update data and the terminal update data.
And S440, performing conflict processing on the update data aiming at the same contact in the cloud update data and the terminal update data, and determining cloud part data of the cloud synchronous update data aiming at the same contact and terminal part data of the terminal synchronous update data.
The cloud updating data comprises cloud adding data, cloud modifying data and cloud deleting data, and the terminal updating data comprises terminal adding data, terminal modifying data and terminal deleting data. The cloud updating data and the terminal updating data are respectively the updating data of the cloud address book and the updating data of the terminal address book after the last synchronization and before the current synchronization.
When conflict processing is performed, the terminal address book data in the synchronization is mainly taken as a reference, the terminal update data is updated to the cloud address book, conflict processing can be performed on the cloud update data and the terminal update data according to the conflict processing principle in the table 1, the cloud update data is updated to the terminal address book, and the terminal update data is updated to the cloud address book. In table 1, the content identity means that the actual data in the address book is the same, and the content identity or the entry key identity is the same as the content in the terminal update data or the entry key identity. In table 1, the cloud modified data indicates which data is specifically modified into which data, and if data 1 is modified into data 2, when the terminal address book is modified according to the cloud modified data, if the terminal address book does not have data 1, the terminal address book does not need to be modified, and only when data 1 exists, the terminal address book is correspondingly modified, and other processing is similar. For example, the mobile phone number of zhang san in the cloud address book is modified from 13812345678 to 13901001100, and the corresponding entry primary key is 22, so the cloud modification data can be recorded as the entry primary key 22, the contact zhang san, the modification content is a mobile phone number, the original mobile phone number is 13812345678, and the modified mobile phone number is 13901001100. When the address book synchronization is carried out between the terminal and the cloud, if the mobile phone number 13812345678 does not exist in the address book of the terminal, the modification is not needed; if the mobile phone number 13812345678 exists in the terminal address book, the corresponding item primary key is 22, and the contact is Zhang III, the mobile phone number 13812345678 is modified to 13901001100.
TABLE 1 Conflict handling principles for the same contact
After performing conflict processing according to the conflict processing principle in table 1, cloud part data of the cloud synchronous update data and terminal part data of the terminal synchronous update data for the same contact can be determined.
S450, according to the update data of the different contact persons in the terminal update data and the cloud part data, cloud synchronous update data are determined, and according to the update data of the different contact persons in the cloud update data and the terminal part data, the terminal synchronous update data are determined.

And S460, updating the cloud address book according to the cloud synchronous updating data, and sending the terminal synchronous updating data to the terminal so as to update the terminal address book of the terminal.
According to the technical scheme, on the basis of the embodiment, the process of performing conflict processing on the update data of the same contact in the cloud update data and the terminal update data is further defined, and the synchronization accuracy is guaranteed.
On the basis of the above technical solution, after the terminal synchronization update data is issued to a terminal to update a terminal address book of the terminal, the method further includes:
and the receiving terminal updates the corresponding entry main key of the cloud address book and the terminal address book identification stored in the cloud according to the entry main key of the terminal address book formed after the terminal address book is updated by the terminal synchronous updating data.
