Description

Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for synchronizing data between service processes.
Background
In the conventional mobile communication system, in a multi-process scenario, service processes such as user registration, full duplex point call, half duplex point call, and group call are performed by a service process (core process) for processing a Session Initiation Protocol (SIP) message, and a Zero Message Queue (ZMQ) message of a user is performed by a base.
As shown in fig. 1, after the user registers in the core process, the core process updates some user variable information. Then, the user variable information on the core process is synchronized to the base process. When the reset of the core process occurs in the server, the base process still works normally, so that after the core process is restarted, the base process needs to synchronize partial attribute data of all users to the core process, so that the core process can normally process the SIP message.
The inventor discovers that in the process of implementing the invention: in practical application, by adopting the technical scheme, the speed of synchronizing the user data to the core process by the base process after the core process is restarted is very low. After the inventor analyzes the existing scheme, the reason that the problems exist is found that:

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 2 is a schematic method flow diagram of an embodiment of the present invention, and as shown in fig. 2, the method for synchronizing data between service processes implemented in the embodiment mainly includes:
step 201, after the first process is restarted, the second process screens out the encrypted attribute data of the user of the specified type from the user data maintained by the process.
The first process is a business process for processing SIP messages, and the second process is a business process for processing messages in a zero message queue ZMQ; the user of the appointed type is an encryption terminal user of the core network.
In this step, it should be noted that, by analyzing the use of the data synchronized with the first process after the restart of the second process, the inventor finds that: after the second process is restarted, only the encrypted attribute data of a part of the users, which are core network terminals and users of the encrypted terminals, need to be used, while for other users, their encrypted attribute data are useless for the second process. Based on this, in this step, in order to improve the efficiency of the second process synchronizing data to the first process after the first process is restarted, only the encrypted attribute data of the encrypted end users of all the core networks are synchronized to the first process, instead of synchronizing the encrypted attribute data of all the users to the first process, so that when the number of users in the system is large, a higher synchronization speed can still be obtained, thereby avoiding the influence on the performance of the server.
Specifically, the first process may be a core process in an existing system, but is not limited to this, as long as the first process is a service process for processing an SIP message in a system to which the present solution is applied.
The second process may be a base process in an existing system, but is not limited thereto, as long as the second process is a business process for processing the zero message queue ZMQ message in the system to which the present solution is applied.
Step 201, the second process synchronizes the screened data to the first process.
Preferably, in this step, when performing data synchronization, a method different from the method in the prior art in which data of only one user is synchronized at a time and data synchronization is performed one by one user may be adopted, but data of multiple users are synchronized at a time, so as to further increase the synchronization speed, and specifically, the screened data may be synchronized to the first process by using the following method:
step a, extracting encrypted attribute data of M users from the screened data, splicing the encrypted attribute data of the M users, and synchronizing a splicing result to the first process at one time;
if the data which is not extracted currently in the screened data comprises at least N user encryption attribute data, M is equal to N, and otherwise, M is equal to K; n is the maximum number of users corresponding to the preset single synchronous data, and is greater than 1; and K is the number of users corresponding to the data which are not extracted currently.
And b, judging whether the screened data contains data which is not extracted, and if so, returning to the step a.
In the above method, N is used to define how many users' data can be synchronized at a time, and a person skilled in the art may set a suitable value of N according to the processing capacity of the actual server and the number of users, for example, the value may be 1000, but is not limited thereto.
Preferably, in order to facilitate the first process to quickly and accurately parse the data synchronized by the second process, the following splicing rules may be adopted to splice the encrypted attribute data of the M users synchronized each time by using a preset first connector and a preset second connector:
and splicing the encrypted attribute data of the M users according to a preset splicing rule by using a preset first connector and a preset second connector.
Wherein the stitching rule comprises: connecting the user number and the encrypted attribute data belonging to the same user by using the first connector; and for adjacent data belonging to different users, connecting by using the second connector, wherein the first connector is different from the second connector.
Based on the splicing rule, the related data (including the user number and the encryption attribute data) of each user can be concatenated for the encryption attribute data of the M users one by one, so that the data of the users can be synchronized to the first process at one time.
Specifically, the first connector may be "|", and the second connector may be ",", where the form of the splicing result is as follows:
user number 1| user number 1 encryption variable, user number 2| user number 2 encryption variable, user number 3| user number 3 encryption variable, … user number i | user number i encryption variable.
In practical applications, a person skilled in the art may set the first connector and the second connector according to actual needs.
Preferably, after the second process splices the user data based on the rule, the splicing result of the encrypted attribute data of the M users can be synchronized to the first process at one time by adopting the following method:
the second process sends the splicing result to the first process at one time;
and the first process analyzes the received splicing result according to the splicing rule to obtain the encryption attribute data of the M users.
In the method, after the splicing result received by the first process, the splicing result can be analyzed according to the splicing rule adopted by the second process, so that the encrypted attribute data of each user can be obtained. Namely: specifically, the first process may obtain, in the concatenation result, each sub-character string connected by the second connector by using the second connector, where each sub-character string corresponds to data of one user, and then obtain, by searching the first connector in the sub-string, the user number and the encryption attribute data of the corresponding user connected by the first connector.
Corresponding to the method, the application also provides a data synchronization device among business processes, which comprises: a processor to:
after the first process is restarted, according to an instruction of a second process, screening out encryption attribute data of a user of a specified type from user data maintained by the second process, and synchronizing the screened out data to the first process;
the first process is a business process for processing SIP messages, and the second process is a business process for processing messages in a zero message queue ZMQ; the user of the appointed type is an encryption terminal user of the core network.
Preferably, the processor is specifically configured to, according to the instruction of the second process, screen out encryption attribute data of a user of a specified type from user data maintained by the second process, where the encryption attribute data includes:
a. extracting encrypted attribute data of M users from the screened data according to the instruction of the second process, splicing the encrypted attribute data of the M users, and synchronizing a splicing result to the first process at one time;
if the data which is not extracted currently in the screened data comprises at least N user encryption attribute data, M is equal to N, and otherwise, M is equal to K; n is the maximum number of users corresponding to the preset single synchronous data, and is greater than 1; k is the number of users corresponding to the data which are not extracted currently;
b. and c, judging whether the screened data contains data which is not extracted, if so, returning to the step a.
Preferably, the processor is specifically configured to splice the encrypted attribute data of the M users, including:
splicing the encrypted attribute data of the M users by using a preset first connector and a preset second connector according to a preset splicing rule, wherein the splicing rule comprises: connecting the user number and the encrypted attribute data belonging to the same user by using the first connector; and for adjacent data belonging to different users, connecting by using the second connector, wherein the first connector is different from the second connector.
