Embodiment 1
[0086] The embodiment of the present invention provides an always-on service implementation method, such as image 3 As shown, the processing flow of the method in this embodiment includes the following steps:
[0087] Step 301: The CS sends at least one CS registration request message to the PS deployed inside the firewall at least once, and the PS receives the CS registration request message sent by the CS deployed outside the firewall.
[0088] When the CS is started, a long TCP connection between the CS and the PS needs to be established through the CS registration process. Since the firewall device restricts the IP address of the CS, the CS registration process does not require complex authentication logic.
[0089] After starting the CS registration process, the CS sends a CS registration request message to the PS. Since the CS is deployed outside the firewall and the PS is deployed inside the firewall, the firewall needs to set IP address filtering rules. Only the CS can estab...
Embodiment 2
[0142] The embodiment of the present invention provides a CS, such as Figure 5 As shown, the CS includes: a first sending unit 501 and a first receiving unit 502, where:
[0143] The first sending unit 501 is configured to send a CS registration request message to the push service server PS deployed in the firewall at least once, where the CS registration request message includes the IP address of the CS, and the IP address of the CS is used for Passing the CS registration request message to the PS through a firewall;
[0144] The first receiving unit 502 is configured to correspondingly receive at least one CS registration response message returned by the PS, and establish at least one first long connection with the PS;
[0145] The first receiving unit 502 is further configured to receive an AOE registration request message sent by the always-on engine AOE, create a corresponding CS session session for the AOE according to the AOE registration request message, and record the CS Se...

Abstract
The embodiment of the present invention discloses a method for realizing an always-on service. The method includes: at least once, the CS deployed outside the firewall sends a CS registration request message to the PS deployed inside the firewall, and the CS correspondingly receives the at least once The CS registration response message returned by the PS, establish at least one first long connection with the PS; receive the AOE registration request message sent by the AOE, and select a first long connection from the at least one first long connection as The first long connection of the AOE, and forward the AOE registration request message to the PS through the first long connection of the AOE; receive the AOE registration response message returned by the PS through the first long connection of the AOE, and send The PS Session ID in the AOE registration response message is deleted and forwarded to the AOE. The embodiment of the invention also discloses a device for realizing the always-on service.
Description
Technical field [0001] The invention relates to the field of data services, in particular to a method and device for realizing always-on services. Background technique [0002] Always On / IP Push technology is a technology in which the server actively sends information to the client, and it is currently widely used in the field of mobile communications. Through the always-on technology, the server can actively and timely push important information to the user terminal, so that the user terminal can receive information anytime and anywhere, which provides great convenience for users. [0003] The always-on technology is a long connection technology based on Transmission Control Protocol / Internet Protocol (TCP / IP). The user terminal contains a client related to the business, and the client needs to maintain a TCP connection with the server. Connection, the server can push information to the client when the connection is valid. [0004] For the convenience of description, the client in...
