Detailed Description
The technical solution in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Before introducing the line agent method provided in the embodiment of the present application, some concepts related to the embodiment of the present application are introduced:
proxy Server (Proxy Server), which is a Server for Proxy network users to obtain network information; the proxy server is a transfer station of network information, an intermediate proxy mechanism between a source host and a destination host, for example, an intermediate proxy mechanism between a host in a personal network and a server of an Internet (Internet) service provider, and is responsible for forwarding legal network information, controlling and registering the forwarding.
Freeswitch is a free and open-source software-based telephone exchange, also understood to be a soft-switching system that communicates using an IP network; by adopting the Mozilla Public License (MPL) authorization protocol, the core library libfreeswitch of FreeWITCH can be embedded in other systems or products, and can also exist as a single application.
Session Initiation Protocol (SIP), also known as Session Initiation Protocol, is a multimedia communication Protocol established by the Internet Engineering Task Force (IETF), a text-based application-layer control Protocol, proposed as a standard for creating, modifying and terminating interactive user sessions involving various multimedia elements including video, voice, instant messaging, online games, virtual reality, and the like.
Please refer to fig. 1, which is a schematic flow chart of a line agent system according to an embodiment of the present application; the line agent system herein may include: the system comprises a proxy server, a first terminal and a second terminal; the proxy server is a server used by a line agent, the proxy server is communicated with a first terminal of a line demand party through the internet, the first terminal can send a VoIP call request to the proxy server, the proxy server is communicated with a second terminal corresponding to a telephone number in the call request, specifically, the proxy server can use line resources of the line demand party to call the second terminal corresponding to the telephone number, and after the second terminal answers the call request, communication connection between the first terminal and the second terminal can be established. For collaborating with line providers and the like. The line proxy method provided by the embodiment of the present application may be executed by the above proxy server, where the proxy server refers to a server having a function of executing a computer program.
The line agent method provided by the embodiment of the application can be applied to a proxy server, namely, the proxy server executes the method, and the line agent method has the main idea that whether a line needs to use a line agent or not is distinguished by using prefix strings, and different line demand parties are distinguished to realize line agents to replace partial functions in a VOS, so that the condition that a large amount of memory resources are occupied by loading the VOS to cause insufficient memory resources is avoided, and the transmission efficiency of the line agent is effectively improved.
Please refer to fig. 2, which is a schematic flow chart of a line agent method according to an embodiment of the present application; the above-mentioned proxy server may be developed based on FreeS WITCH to implement various functions of a line proxy method, which may include:
step S110: the proxy server receives a VoIP call request based on Internet protocol sent by the first terminal, and extracts a universal unique identification code from the call request.
The Universal Unique Identifier (UUID) refers to an Identifier for identifying information in a computer system, and the UUID is independent of registration and allocation of a central authority, and can be understood as a character string with global uniqueness.
The embodiment of step S110 described above is, for example: the method comprises the steps that a first terminal sends a VoIP calling request to a proxy server through the Internet, the proxy server receives the VoIP calling request sent by the first terminal, and after receiving the VoIP calling request, the proxy server extracts a universal unique identification code UUID from the calling request; it should be noted that the UUID in the embodiment has two cases: in the first case, if the VoIP call request is sent by the line demander, the UUID must include a prefix string, for example: suppose the UUID is 2020jd152 x 8888, where 2020 is the first prefix string, jd is the second prefix string, and 152 x 8888 is the phone number; in the second case, if the VoIP call request is not sent by the line demander but by the normal calling subscriber, the UUID must not include the prefix string, for example: the UUID sent by the normal calling subscriber is 152 x 8888 equal telephone number. Since the proxy server can only allow the business use of the line demand party and does not allow the use of the ordinary calling user, the call request sent by the ordinary calling user can be directly rejected.
After step S110, step S120 is performed: if the first prefix string is identified from the universally unique identification code, the proxy server extracts the routing information from the universally unique identification code.
The embodiment of step S120 described above is, for example: judging whether the first prefix string is identified from the universal unique identification code, wherein the specific identification modes include a plurality of modes: a first recognition mode, such that the first letter is sequentially matched from front to back, specifically for example: assuming that the UUID is 2020jd152 × 8888, the startpath function in the string is used to determine whether the UUID "2020 jd152 × 8888" is beginning with the first prefix string "2020", if so, it is determined that the first prefix string is identified from the UUID, and if not, it is not identified from the UUID; the second identification mode is identified according to the boundary between fields; assuming that the universally unique identifier UUID is 2020jd152 x 8888, it can be identified that all letters "jd" are the second prefix string, the number "2020" before the letter is the first prefix string, and the number "152 x 8888" after the letter is the telephone number; the first prefix string is an identification string that requires the use of the line agent. Of course, the specific format of the universal unique identification code can be set according to specific situations, for example, separators are set between the first prefix string, the second prefix string and the telephone number, and the like, and the separators include, but are not limited to, vertical lines, slashes, dash marks, and the like.
After determining whether the first prefix string is identified from the universally unique identifier, the method may further include: if the first prefix string is identified from the universal unique identification code, it indicates that the call request corresponding to the universal unique identification code is sent by the line demander, and then the routing information needs to be extracted from the universal unique identification code, which specifically includes: assuming that the universally unique identifier UUID is 2020jd152 × 8888, the first prefix string "2020" is directly removed from the UUID, and the routing information "jd 152 × 8888" is obtained; if the first prefix string is not identified from the universal unique identification code, it indicates that the call request is not issued by the line requesting party, and the call request may be directly rejected, for example: assuming that the UUID is 152 × 8888, the first prefix string cannot be identified from the UUID "152 × 8888". Since the proxy server is only used by the business of the line demand party and does not allow the use of the ordinary calling user, the call request sent by the ordinary calling user can be directly rejected.
Please refer to fig. 3, which is a schematic diagram illustrating a processing procedure of the universal unique identification code according to an embodiment of the present application; in a specific implementation, the identification of the prefix string can be implemented using two profiles of configuration call rules in FreeSWITCH, where the two profiles of configuration call rules include: xml for identifying the public.xml requiring the line agent in response to the external request, and default.xml for identifying the terminal host of the line demander in response to the internal request; xml can be a softphone registered on the FreeSWITCH, and the FreeSWITCH can call other phone numbers by using the softphone, and certainly, the configurable files public.xml and default.xml can be mutually called, namely, a call request from the outside is transferred to internal processing, or the internal call request is transferred to external processing, so that the flexibility of call request processing and line resource use is improved. Specifically, add the identifier 2020 that needs to use the line agent to the configurable file public.xml, i.e., automatically identify the first prefix string "2020" from the universal unique identifier "2020 jd152 × 8888" using the freesswitch, and retain the routing information "jd 152 × 8888".
After step S120, step S130 is performed: if the second prefix string is identified from the routing information, the proxy server divides the routing information into the second prefix string and the telephone number.
The embodiment of step S120 described above is, for example: assuming that the routing information is jd152 x 8888, the proxy server may identify a second prefix string "jd" from the routing information "jd 152 x 8888" according to the boundary between the second prefix string and the phone number, and then divide the routing information "jd 152 x 8888" into the second prefix string "jd" and the phone number "152 x 8888"; the second prefix string and the telephone number may be demarcated by letters and numbers, or separators may be used as demarcations between the second prefix string and the telephone number according to specific situations; the delimiter includes, but is not limited to, a vertical line, a slash line, a dash, and the like, and the second prefix string is an identification string of the line demander.
In a specific practical process, referring to fig. 3, the proxy server may also use FreeSWITCH to divide the routing information into a second prefix string and a phone number, for example: xml adds the identifier jd of the end host of the routing partner to the configurable file default, i.e. the second prefix string "jd" is identified from the routing information "jd 152 × 8888" using freesswitch, and the telephone number "152 × 8888" is reserved.
After step S130, step S140 is performed: and the proxy server acquires the target line resource according to the second prefix string and calls a second terminal corresponding to the telephone number by using the target line resource so as to realize line proxy.
Line resources refer to resources provided by a line provider associated with establishing a connection to a communication line, where the line includes, but is not limited to: analog trunks, digital trunks, VoIP lines, and IMS lines, among others; the IMS line is a line based on a SIP protocol registration core network, and the VoIP line is used to digitize analog signals and transmit the digitized analog signals in real time over an IP network in the form of data packets.
There are many embodiments of the step S140, including but not limited to the following:
in a first embodiment, a target route resource is matched and searched from a database, and the embodiment includes: requesting a back-end server written by using a JAVA language by using a Lua language script or a Python language script, wherein the back-end server can search a target line resource meeting a preset condition in a matching manner from line resources of a database, and the preset condition is that the concurrence number of the target line resource is less than a preset threshold value and a prefix string corresponding to the target line resource is a second prefix string; the preset threshold value here may be set according to specific situations, specifically for example: the preset threshold is set to 8, 9 or 10, etc. In the implementation process, the target line resource meeting the condition that the concurrency number of the target line resource is smaller than the preset threshold value and the like is searched from the line resources of the database, so that the problem of insufficient memory resources caused by the use of the target line resource with a large concurrency number is solved, and the transmission efficiency of the line agent is effectively improved.
In a second embodiment, a target line resource is randomly selected from a plurality of line resources matched in a database, and the method includes: judging whether a plurality of line resources in a database meet preset conditions by using a Lua language script or a Python language script; if the plurality of line resources in the database meet the preset condition, determining the randomly selected line resource in the plurality of line resources as a target line resource, wherein the preset condition is that the concurrence number of the target line resource is less than a preset threshold value, and a prefix string corresponding to the target line resource is a second prefix string; the preset threshold value here may be set according to specific situations, specifically for example: the preset threshold is set to 8, 11 or 13, etc.
In a third embodiment, in a case where only one line resource is matched in the database, a target line resource is determined according to whether a concurrence number of the line resource satisfies a condition, the method includes: acquiring a line resource from the line resources of the database, and acquiring the concurrency number of the line resource; if the concurrency number of the line resources is smaller than the preset threshold, determining the line resources with the concurrency number smaller than the preset threshold as target line resources; the preset threshold value here may be set according to specific situations, specifically for example: set the preset threshold to 3, 5 or 7, etc. The database described above may include: a relational database and a cache database; among the relational databases that may be used are: mysql, PostgreSQL, Oracle, and SQLSever, etc., cache databases that may be used include: memcached and Redis, etc. The above embodiment of obtaining a line resource from line resources of the database may specifically include: judging whether the line resource is obtained from the buffer database according to the unique identifier of the line resource; and if the line resource is not obtained from the cache database according to the unique identifier of the line resource, obtaining the line resource from the relational database.
A fourth embodiment, determining a target line resource according to whether the concurrency number of the line resource in the cache database and the concurrency number in the relational database satisfy a preset relationship, includes: acquiring a first concurrency number of the line resource from a buffer database, wherein the first concurrency number refers to an actual concurrency number, and acquiring a second concurrency number of the resource line from a relational database, wherein the second concurrency number refers to a preset concurrency number threshold, namely the actual concurrency number cannot exceed the second concurrency number; if the size relationship between the actual concurrency number and the preset concurrency number meets the preset relationship, determining the line resource as the target line resource, wherein the preset relationship can be set according to specific conditions, for example: the actual concurrency number is greater than 0.5 times, 0.7 times or 0.8 times of the preset concurrency number, and the like. It can be seen that the selection of the target line resource may be determined by the actual concurrency number of the line resource in the cache database and the preset concurrency number in the relational database.
In the implementation process, a VoIP call request based on Internet protocol sent by a first terminal is received; then extracting a universal unique identification code from the call request, and under the condition that a first prefix string is identified from the universal unique identification code, dividing the routing information extracted from the universal unique identification code into a second prefix string and a telephone number; finally, the target line resource is obtained according to the second prefix string, and the target line resource is used for calling a second terminal corresponding to the telephone number, so that the line agent function is realized; that is to say, whether a line needs to use a line agent is distinguished by using the prefix string, and different line demand parties are distinguished to realize the line agent to replace part of functions in the VOS, so that the situation that the VOS is loaded to occupy a large amount of memory resources to cause insufficient memory resources is avoided, and the transmission efficiency of the line agent is effectively improved.
Optionally, in this embodiment of the present application, after extracting the universal unique identifier from the call request, line bridging may be performed, where the embodiment includes: the first terminal and the second terminal are line bridged according to the universal unique identifier, and it should be noted that line bridging herein refers to virtual bridging, and it is understood that bridging is performed at a data link layer, a network layer and an application layer, and not actual physical bridging.
