The SIP registration service device may use a general file system, a database system or a data cache system to store data, where the stored system is in the prior art and will not be described herein.
The SIP registration service device is mainly composed of 5 modules:
(1) An external number management module: external numbers within an external SIP system, which can perform SIP registration, de-registration, SIP calls on the external SIP system, which can include an IMS system of a telecommunications operator, a SIP communication service provider, etc., are added to, deleted from, and/or connected to the SIP registration service device.
(2) The module registers and de-registers the foreign agent external number SIP: the external number can be paged from the external SIP system, requiring the external number SIP to be registered with the external SIP system. The SIP registration service device completes registration and deregistration of the external number to the external SIP system agent through the module.

(5) An association module between the internal number and the external number: to realize the non-difference call between the internal number and the external number in the SIP call, the internal number and the external number are required to be associated, the internal number is mapped to one external number of a public external number pool by distributing the internal number to each terminal, and the intercommunication of the internal number and the external number call is realized by adopting a forwarding technical scheme. The content that these two numbers need to be associated mainly includes two aspects: 1. binding relation association between the internal number and the external number; 2. the SIP registration-de-registration procedure is associated between the internal number and the external number.
It will be understood by those skilled in the art that the following SIP registration service method is performed by the SIP registration service system or the SIP registration service apparatus.
Referring to fig. 3, the present invention provides a SIP registration service method, which in a first embodiment of the SIP registration service method includes the steps of:
step S100, receiving binding request information of binding internal numbers sent by a client terminal;
the client terminal refers to communication terminal equipment in which a user needs to bind an internal number.
Step S200, based on the binding request information, determining the identity information of the client terminal, and converting the identity information into an internal number corresponding to the identity information;
specifically, as shown in fig. 8, the internal number is created by the SIP registration service apparatus. In one embodiment, the SIP registration service device generates a globally unique internal number corresponding to the client terminal according to the identity information of the client terminal and a preset number generation algorithm, writes the globally unique internal number into the data storage device, and returns the globally unique internal number to the client terminal. In another embodiment, according to the identity information of the client terminal, the internal number attribute mapped by the identity information is determined from a preset information mapping table, and according to the internal number attribute, the internal number corresponding to the internal number attribute is selected from an internal number pool (a set of all internal numbers generated in advance) stored in the data storage device, and returned to the client terminal.
As known to those skilled in the art, since the internal number is used for the client terminal to perform SIP registration and cancellation with the SIP registration service device and subsequent call service, in order to ensure the uniqueness of each client terminal, when the internal number is created, that is, when the client terminal requests to obtain the internal number from the SIP registration service device, the client terminal is required to provide identification information representing uniqueness of its own identity.
The client terminal may include a hardware SIP terminal device and a soft SIP terminal. For the hardware SIP terminal equipment, the hardware SIP terminal equipment can comprise an SIP telephone, an intelligent sound box, an intelligent television, a camera and the like, and the product serial code of the equipment is required to be used as identity information. For a soft SIP terminal of a computer desktop, the MAC (Media Access Control, medium access control) address of the computer is required to be used as identity information, and for OTT (Over The Top) application software on a mobile phone, an account number used for logging in OTT application software is required to be used as identity information.
Step S300, obtaining an external number to be bound, carrying out association binding on the internal number and the external number, and sending a registration request corresponding to the external number to an external SIP system;
It can be understood that the internal numbers are in one-to-one correspondence with the identification information, but one external number can be bound by associating a plurality of internal numbers, and one external number can be bound by associating one internal number.
Specifically, as shown in fig. 9, the external number is created by the external SIP system, and is added to the SIP registration service system, so that the SIP registration service system can proxy and register to the external SIP system. The user or the third party system adds or deletes the external number to the SIP service device through the external HTTP interface provided by the SIP registration service device, and when the SIP service device receives the added or deleted external number, the data is written into the data storage device.
The external SIP system is configured to send a registration request of an external number to the external SIP system, and periodically write the registration result information into the data storage device, and the SIP registration service device periodically queries the data storage device for the registration result information.
Step S400, according to the registration result information returned by the external SIP system based on the registration request, whether the registration success authority of the internal number in the internal SIP system is opened is determined.
Further, the step S400: the step of determining whether the registration success authority of the internal number in the internal SIP system is opened according to the registration result information returned by the external SIP system based on the registration request includes:
step a, if the received registration result information returned by the external SIP system based on the registration request is that the registration is successful, the registration success authority of the internal number in the internal SIP system is open;
if the registration result information of the external number is that the registration is successful, the registration success authority of the internal number in the internal SIP system is set to be open, so that the internal number is allowed to register successfully in the internal SIP system, for example, when the internal number is in a cancellation state in the internal SIP system, the internal number is triggered to register successfully in the internal SIP system, and when the internal number is in a registration success state in the internal SIP system, the internal number is not processed.
And b, if the received registration result information returned by the external SIP system based on the registration request is that the registration fails, the registration success authority of the internal number in the internal SIP system is closed.
If the registration result information of the external number is that the registration fails, the registration success authority of the internal number in the internal SIP system is set to be closed, so that the internal number is not allowed to be successfully registered in the internal SIP system. For example, when the internal number is in the registration success state in the internal SIP system, the internal number is triggered to be logged off in the internal SIP system and logged off successfully, and when the internal number is in the login success state in the internal SIP system, the internal number is not processed. It should be noted that, the external number is periodically registered with the external SIP system, and the registration result information is written into the data storage device, and the SIP registration service device correspondingly periodically queries the data storage device for the registration result information, so as to determine in real time (periodically) whether the internal number opens the registration success authority in the internal SIP system.
The embodiment determines the identity information of the client terminal based on the binding request information by receiving the binding request information of the binding internal number sent by the client terminal, and converts the identity information into the internal number corresponding to the identity information based on the identity information corresponding to the client terminal, thereby creating a globally unique internal number corresponding to the client terminal based on the identity information corresponding to the client terminal, then, by obtaining the external number to be bound, associating and binding the internal number with the external number, and sending a registration request corresponding to the external number to an external SIP system, so that each internal number and external number have an association binding relation, when the external number is added to a SIP registration service system, the SIP registration service system can perform proxy registration on the external SIP system, and further, by determining whether the registration success authority of the internal number and the external number are open based on the registration result information returned by the external SIP system, the internal SIP system generates registration association, and drives the respective SIP number and the external number through shared SIP registration information, if the internal number and the internal SIP registration success registration authority of the external SIP system is not allowed to be successfully registered with the internal SIP system is successfully registered, if the internal SIP registration of the internal SIP system is successfully registered with the external SIP system is successfully registered, the internal SIP registration of the internal SIP system is not allowed, and if the internal SIP registration of the internal SIP registration success of the internal SIP registration system is successfully performed, the capabilities of the SIP registration service system are extended.
Further, referring to fig. 4, based on the first embodiment of the present invention, a second embodiment of the SIP registration service method of the present invention is proposed, and in this embodiment, after the step of performing association binding on the internal number and the external number, the method includes:
step S310, inquiring whether the internal SIP system has the registration record information of the internal number;
and judging whether the internal number is registered for the first time by inquiring whether the internal SIP system has the registration record information of the internal number.
The SIP registration service device should periodically query the data storage device for registration record information of whether the internal SIP system has the internal number.
If the internal SIP system has the registration record information of the internal number, step S400 is executed: determining whether the registration success authority of the internal number in the internal SIP system is opened according to registration result information returned by the external SIP system based on the registration request;
if the internal SIP system has the registration record information of the internal number, the internal number is determined not to be registered for the first time. If the internal number is not the SIP registration initiated to the SIP registration service device for the first time, inquiring the registration result information of the external number related to the internal number on the data storage device, judging whether the external number is successfully registered in the external SIP system according to the registration result information, if the received registration result information returned by the external SIP system based on the registration request is the successful registration, setting the registration success authority of the internal number in the internal SIP system to be open, and if the received registration result information returned by the external SIP system based on the registration request is the registration failure or is cancelled, setting the registration success authority of the internal number in the internal SIP system to be closed.
If the internal SIP system does not have the registration record information of the internal number, step S320 is executed: and sending a registration request corresponding to the external number to an external SIP system.
If the internal SIP system does not have the registration record information of the internal number, the internal number is determined to be registered for the first time. If the internal number is SIP registration initiated to the SIP registration service device for the first time, inquiring the external number bound by the internal number, triggering the external number to register to an external SIP system, and writing the registration result information of the external number into the data storage device.
In this embodiment, by querying whether the internal SIP system has the registration record information of the internal number, if the internal SIP system has the registration record information of the internal number, the step of determining whether the registration success authority of the internal number in the internal SIP system is open according to the registration result information returned by the external SIP system based on the registration request is performed, so as to determine whether the external number is registered in the external SIP system according to the registration result information, if the received registration result information returned by the external SIP system based on the registration request is registration success, the registration success authority of the internal number in the internal SIP system is set to be open, and if the received registration result information returned by the external SIP system based on the registration request is registration failure or logged out, the registration success authority of the internal number in the internal SIP system is set to be closed, thereby realizing the association of registration and logging-out between the internal number and the external number, effectively controlling the registration number of the internal number in the internal SIP system, and reducing the load pressure of the internal SIP system. And further, if the internal SIP system does not have the registration record information of the internal number, the step of sending a registration request corresponding to the external number to the external SIP system is performed, so that when the internal number bound by the external number is registered with the SIP registration service device for the first time, the external number is triggered to register with the external SIP system, and further, the SIP registration process of each SIP is driven by sharing the SIP registration result information of both parties (the internal number and the external number) in each SIP system, that is, when the internal number is judged to initiate SIP registration with the SIP registration service device for the first time, the external number is triggered to register in the external SIP system, so that the external number is successfully registered in the external SIP system, when other communication terminals call the external number through the external SIP system, the internal number bound by the external number is switched to be associated based on the internal SIP system, so as to realize synchronous call response of switching, thereby effectively improving the registration and cancellation of the internal number and the external number, and further expanding the capability of the SIP registration service system.
Further, referring to fig. 5, based on the first embodiment of the present invention, a third embodiment of the SIP registration service method of the present invention is provided, in this embodiment, if the received registration result information returned by the external SIP system based on the registration request is successful in registration, after the step of opening the registration success authority of the internal SIP system, the method includes:
step S500, acquiring registration record information of the internal number in an internal SIP system based on a preset period, and judging whether the registration record information is completely invalid;
if all the registration record information has failed, step S600 is executed: and sending a cancellation request corresponding to the external number to an external SIP system.
Wherein, the preset period-based refers to preset periods every interval. Wherein the expiration of the registration record information may characterize the expiration of the registration record information. It will be appreciated that if the internal number is de-registered with the internal SIP system, it is indicated that the registration record information for the internal SIP system has expired. As described above, one external number may be bound to a plurality of internal number associations, and one external number may be bound to one internal number association. When a plurality of internal numbers are associated and bound with one external number, the logout request corresponding to the external number is sent to the external SIP system only when all the registration record information corresponding to all the internal numbers which are associated and bound with the external number are invalid.
It should be noted that, it is necessary to determine whether all SIP registration information of all internal numbers bound to the external number has expired, and if all SIP registration information has expired, immediately or after (for example, 30 minutes after) logging out to the external SIP system, and delete external account registration result information on the storage device.
According to the embodiment, whether the registration record information of the internal number in the internal SIP system is completely invalid is judged by acquiring the registration record information based on a preset period, if the registration record information is completely invalid, a cancellation request corresponding to the external number is sent to the external SIP system, so that cancellation association is generated between the internal number and the external number, the respective SIP cancellation processes are driven by sharing the SIP cancellation result information of the opposite side, namely, whether all the internal numbers associated with the external number are completely cancelled by the internal SIP system is judged, if all the internal numbers are cancelled, the cancellation request of sending the external number to the external SIP system is triggered, so that the cancellation of the external number is successful, the association cancellation between the internal number and the external number is realized, the registration quantity of the external number to the external SIP system is effectively controlled, the load pressure of the external SIP system is reduced, and the capability of the SIP registration service system is further expanded. In the SIP registration service system, the internal number and the external number drive respective SIP cancellation processes by sharing the SIP cancellation result information of the opposite party.
Further, the step of obtaining the external number to be bound includes:
step c, judging whether the internal number has authentication information;
further, before the step of determining whether the internal number has authentication information, the method further includes:
step v, judging whether the internal number exists or not;
if the internal number exists, executing the step c, namely judging whether the internal number has authentication information or not.
Step d, if the internal number has authentication information, judging whether the internal number is successfully authenticated or not based on the authentication information;
and e, if the authentication of the internal number is successful, executing the step of acquiring the external number to be bound.
Before the SIP registration service device initiates SIP registration of the external number to the external SIP system, the SIP registration service device performs content authentication such as presence and authentication on the internal number.
In the embodiment, before the external number initiates the SIP registration to the external SIP system, the SIP registration service device performs content authentication such as presence and authentication on the internal number, so as to ensure the validity of the internal number.
Further, referring to fig. 6, based on the first embodiment of the present invention described above, a fourth embodiment of the SIP registration service method of the present invention is proposed, and in this embodiment, the step of obtaining the external number to be bound includes:
Step S710, detecting whether the internal number has a specified binding identifier;
and judging whether the internal number designates the external number to be bound or not by detecting whether the internal number has the designated binding identifier or not.
If the internal number has the specified binding identifier, step S720 is executed: and determining the appointed external number corresponding to the appointed binding identification, and taking the appointed external number as the external number to be bound.
If the internal number has the specified binding identifier, determining that the internal number specifies an external number to be bound, and executing: and determining the appointed external number corresponding to the appointed binding identification, and taking the appointed external number as the external number to be bound.
Further, after the step of detecting whether the internal number has the designated binding identifier, the method further includes:
if the internal number does not have the designated binding identifier, step S730 is executed: and selecting a hit external number from a preset public external number group, and taking the hit external number as an external number to be bound.
Specifically, based on a preset load balancing allocation algorithm, selecting a corresponding hit external number from a common external number group, and taking the hit external number as an external number to be bound.
If the internal number does not have the specified binding identifier, determining that the internal number does not specify the external number to be bound, selecting a corresponding external number from a public external number group (public external number pool) through a preset load balancing allocation algorithm, and performing association binding on the selected external number and the internal number.
When the user or the third system requests the internal number to bind the external number from the SIP registration service device, the external number bound by the internal number is not specified, and the SIP registration service device calculates and distributes an external number for the internal number through a preset distribution algorithm. In order to balance the number of the bound internal numbers of each external public number, a preset load balancing allocation algorithm is adopted to allocate the public external numbers, and the load balancing allocation algorithm can be set by a person skilled in the art according to actual needs, and the embodiment is not limited specifically.
In one embodiment, the load balancing allocation algorithm includes a common external number polling allocation method, that is, by allocating an external number from a common external number group in turn in order for internal number binding by using registration requests of internal numbers, without concern for the case of the external number actually being bound internal number.
In another embodiment, the load balancing allocation algorithm includes a public external number polling allocation method, that is, by a random algorithm of the system, external numbers in the public external number group are randomly selected for internal number binding association according to the total number of the public external number group. As can be seen from the probability statistics theory, as the number of allocation times increases, the actual effect is more and more similar to that of the average allocation of each external number, that is, the effect of the polling allocation algorithm.
In yet another embodiment, the load balancing allocation algorithm comprises a common external number weighted random allocation method, i.e. as with the common external number weighted round robin allocation method, the weighted random method is also allocated according to the weight of the external number. Except that it is to randomly assign external numbers according to weights rather than sequentially.
In another embodiment, the load balancing allocation algorithm includes a common external number minimum association number allocation method, that is, an external number of an internal number least associated at the current time is always allocated from a common external number group every time an external number allocation is requested.
Further, the load balancing allocation algorithm includes an internal number hash allocation method, and the step of selecting a corresponding hit external number from the common external number group based on a preset load balancing allocation algorithm includes:
F, obtaining a hash value based on a hash function according to the internal number;
step g, determining the total number of the public external number group;
step h, based on the hash value and the total number of the numbers, performing modulo operation to obtain the number serial number of the public external number group;
and i, selecting an external number corresponding to the number from the public external number group based on the number, and taking the external number as a corresponding hit external number.
The idea of the internal number hash allocation method is that according to the internal number, a hash value is obtained through hash function calculation, the hash value is used for carrying out modulo operation on the total number of the public external number group, and the obtained result is that the serial number of the external number in the public external number group is to be allocated, namely the allocated external number is positioned in the public external number group through the serial number. When the internal number hash allocation method is adopted for allocation, the same internal number is allocated each time when the common external number group is unchanged in size.
According to the embodiment, the external numbers are selected and allocated through the internal number hash allocation method, so that the number of the internal numbers bound with each external number is balanced, and the utilization rate of the external numbers is effectively improved.
Further, the load balancing allocation algorithm further includes a common external number weighted polling allocation method, and the step of selecting a corresponding hit external number from the common external number group based on the preset load balancing allocation algorithm includes:
step j, determining the number weight ratio of each external number based on the number attribute of each external number in the public external number group;
and k, selecting the external number corresponding to the number weight from the common external number group as the corresponding hit external number according to the sequence from the large number weight ratio to the small number weight ratio.
The different external numbers have different weights in the use degree due to different factors such as telecom tariffs, reliability of number calls, importance degree of numbers and the like, for example, the internal numbers bind the numbers with low telecom tariffs and high reliability of number calls as far as possible. The weighted round robin allocation method is well applicable to this scenario. The weighted polling allocation method allocates the external numbers in sequence from high to low according to the weight of the external numbers, thereby effectively improving the utilization rate of the external numbers. The number of the internal numbers bound to each external number is balanced, and the number weight is set by fully utilizing the number attribute of the external number, so that the requirements of clients are more matched, and the robustness of the SIP registration service in the embodiment of the invention is improved.
In addition, referring to fig. 7, an embodiment of the present invention further provides a SIP registration service apparatus, including:
