Detailed Description
The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, the step numbers in the text are only for convenience of explanation of the specific embodiments, and do not serve to limit the execution sequence of the steps. The method provided by the embodiment can be executed by the relevant terminal device, and the following description takes the VoIP terminal as an execution subject as an example.
As shown in fig. 1, a first embodiment provides a method for failover of a VoIP terminal registration service, including steps S1 to S3:
s1, selecting a server from the servers analyzed according to the domain name as a target server, and sending a registration request to the target server to successfully register on the target server;
s2, sending a communication request to the target server, and performing registration and successive offer detection on the target server when the target server abnormally responds to the communication request;
and S3, if the registration continuation detection fails, reselecting another server as a new target server, and initiating a registration request to the new target server to successfully register on the new target server.
As shown in fig. 2, as an example, in step S1, the VoIP terminal selects one server from several servers as a target server by parsing out a plurality of servers such as IP1, IP2, IP3, etc. or one server of IP1 from the registered domain name by the domain name server, and sends a registration request to the target server to successfully register on the target server. The VoIP terminal may select the server IP1 which is firstly analyzed from the servers as the target server according to the analysis sequence IP1 → IP2 → IP3 → … or IP1 of the servers.
In step S2, after the VoIP terminal is successfully registered in the target server, the VoIP terminal sends a communication request, such as various communication service requests for subscribing, talking or sending short messages, to the target server according to the communication requirement, and when the target server normally responds to the communication request, the target server is considered to be normally operating, and at this time, the VoIP terminal normally performs the communication service, and when the target server abnormally responds to the communication request, the target server is considered to be faulty, and at this time, the VoIP terminal triggers a failover mechanism of the registration service, and performs registration continuation detection on the target server.
In step S3, in the case where a plurality of servers are resolved from the domain name, if the registration continuation detection fails and the target server is considered to be unavailable, the VoIP terminal reselects one server from the servers other than the target server as a new target server, and initiates a registration request to the new target server to successfully register on the new target server. Wherein, the VoIP terminal may select the server IP2, which is firstly parsed except the target server IP1, from the several servers as a new target server according to the parsing order IP1 → IP2 → IP3 → … of the several servers.
In the embodiment, the registration service is associated with the communication service, when the VoIP terminal is registered on one server but cannot normally perform the communication service, the VoIP terminal actively triggers a failover mechanism of the registration service to automatically switch and register on another server, the VoIP terminal can quickly recover the communication service without manual operation or passive waiting for recovery of the registration service, and the VoIP terminal can quickly perform failover when the server is down, so that the communication stability of the VoIP terminal is ensured.
In a preferred embodiment, after reselecting another server as a new target server and initiating a registration request to the new target server to successfully register on the new target server if the registration continuation detection fails, the method further includes: and re-sending the communication request to the new target server, and recovering the communication service when the new target server normally responds to the communication request.
As an example, for the case of resolving a plurality of servers according to the domain name, if the registration continuation detection fails and the target server is considered to be unavailable, the VoIP terminal reselects one server from other servers except the target server as a new target server, initiates a registration request to the new target server to successfully register on the new target server, and after the VoIP terminal successfully registers on the new target server, the VoIP terminal resends a communication request, such as various communication service requests of subscribing, talking or sending short messages, to the new target server according to the communication requirement, and resumes the communication service when the new target server normally responds to the communication request.
According to the embodiment, after the VoIP terminal is automatically switched and registered on another server, the VoIP terminal selects whether to recover the communication service according to the communication requirement, so that the communication service can be rapidly recovered on the premise of considering the communication requirement of the user, and the communication stability of the VoIP terminal is guaranteed.
In a preferred embodiment, if the registration renewal detection fails, reselecting another server as a new target server, and initiating a registration request to the new target server to successfully register on the new target server, further comprising: and if the registration renewal detection fails, the registration request is sent to the target server again after waiting for the registration retry time so as to successfully register on the target server.
As an example, for the case of resolving one server according to the domain name, if the registration continuation detection fails and the target server is considered to be unavailable, the VoIP terminal waits for the registration retry time and then resends the registration request to the target server to be successfully registered on the target server again, and when the VoIP terminal is successfully registered on the target server again, the VoIP terminal resends the communication request to the target server according to the communication requirement, such as various communication service requests of subscribing, talking or sending short messages, and resumes the communication service when the target server normally responds to the communication request.
In the embodiment, when no other server is available for the VoIP terminal to switch registration, the VoIP terminal automatically waits for registration retry time and then sends the registration request to the target server again, and tries registration at regular time, compared with the case of waiting for registration service recovery through manual operation or passively, the waiting time is effectively shortened, when the server goes down, the VoIP terminal can rapidly perform fault transfer, and when the VoIP terminal is registered on the server again, the VoIP terminal selects whether to recover the communication service according to the communication requirement, and can rapidly recover the communication service under the premise of considering the communication requirement of the user, thereby ensuring the communication stability of the VoIP terminal.
In a preferred embodiment, the sending a communication request to the target server, and performing registration continuation detection on the target server when the target server abnormally responds to the communication request specifically includes: and sending a communication request to the target server, and sending a registration renewal probe packet to the target server when the target server cannot respond or erroneously responds to the communication request so as to judge whether the target server is available according to the return data of the target server to the registration renewal probe packet.
Illustratively, the VoIP terminal sends a communication request to the target server, and when the target server cannot respond or erroneously responds to the communication request, the target server is considered to have a fault, at this time, the VoIP terminal generates a registration continuation probe packet according to the registration request, that is, registration register signaling of a standard rfc header field including request uri, from, to, cseq, contact, call-id, content-length, and the like, and sends the registration continuation probe packet to the target server, the target server will make feedback according to the registration register signaling and its own operating state, for example, when the network is not reachable, the target server returns 503, when the account password of the registration register signaling is incorrect, the target server returns 403, and the VoIP terminal judges whether the target server is available according to the return data of the registration continuation probe packet from the target server.
In a preferred embodiment, if the registration renewal detection fails, reselecting another server as a new target server, and initiating a registration request to the new target server to successfully register on the new target server, specifically: if the registration continuation detection fails, another server is sequentially selected as a new target server according to the analysis sequence of the plurality of servers, and a registration request is sent to the new target server until the new target server is successfully registered.
Illustratively, if the registration continuation detection fails, and the target server is considered to be unavailable, the VoIP terminal reselects the server IP2, which is parsed first except for the target server IP1, from among the servers as a new target server according to the parsing order of the servers IP1 → IP2 → IP3 → …, initiates a registration request to the new target server IP2 to be successfully registered on the new target server IP2, and when the VoIP terminal fails to be successfully registered on the new target server IP2, the VoIP terminal continues to select the server IP3, which is parsed first except for the target server IP1 and the server IP2, as a new target server, initiates a registration request to the new target server IP3 to be successfully registered on the new target server IP3, and so on until the VoIP terminal is successfully registered on the new target server.
In order to illustrate the embodiment more clearly, reference may be made to the following application scenarios, which have great advantages for application scenarios in which batches of VoIP terminals are registered on a server, where a failover mechanism of a registration service is triggered by a VoIP terminal in a linkage manner when a communication service is abnormal, rather than simply starting a retransmission mechanism only when the registration fails.

(2) the VoIP terminal needs to initiate registration continuation after 3600s and can renew the registration state, and senses that the downtime of the server is abnormal, and the downtime of the communication service of the VoIP terminal is too long;
(3) if the registration duration of the VoIP terminal is shortened, the traffic bandwidth occupies a large amount in a short time, and the number of the VoIP terminals is large, the bandwidth and the server load balancing pressure can be increased.
2. With the present embodiment:
(1) single server scenario: the VoIP terminal can trigger registration renewal detection, the registration renewal detection has no response, the VoIP terminal updates the registration state into registration failure, operation and maintenance personnel can sense that the server is possibly out of order, and the server is actively checked;
(2) a multi-server scenario: the VoIP terminal triggers the registration renewal detection, the registration renewal detection can be switched to other servers without response, communication services such as conversation and subscription can be quickly recovered, and the communication services of the VoIP terminal are recovered to be normal.
