The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments. It is understood that these embodiments are given only to enable those skilled in the art to better understand and to implement the present invention, and do not limit the scope of the present invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better describe the communication service system and the construction method thereof according to the embodiment of the present invention, fig. 1a and fig. 1a show a network architecture diagram of a conventional communication service system, fig. 1b shows a network architecture of the communication service system according to the embodiment of the present invention, and according to a comparison result between fig. 1a and fig. 1b, a technical solution according to the embodiment of the present invention is better explained.
Referring to fig. 1a, a conventional communication service system employs physical IT (Internet Technology ) servers such as a public network data gateway (PGW) and an access router (LNS), and a communication service system architecture such as an AAA authentication server-an acquisition server-a policy server-an accounting server-a policy server is constructed from below a core network element GGSN of an operator. In order to ensure the reliability of the network architecture, a standby server is designed for various servers in the process of building a communication service system, for example: the access router LNS, the acquisition server and the like adopt a dual-computer backup design. Therefore, the dual-machine backup of a plurality of physical devices is involved, a large amount of device waste is caused, the extension or improvement of the communication service system is involved, the adjustment of the server architecture is involved, and the deployment and adjustment work of the communication service system is very complicated.
Referring to fig. 1b, the communication service system according to the embodiment of the present invention includes: six general servers of three nodes of Node-A, Node-B and Node-C are used to construct virtual second layer tunnel protocol network server VLNS and several function servers. And the two control management switches are connected with the public network through the outlet firewall, and the general server accesses the public network through the control management switches. The VLNS is used for establishing a second layer tunnel protocol virtual private network L2TP VPN channel with the private dial-up network management PGW so as to access the private dial-up network management PGW.
In one embodiment of the invention, the universal server is a standard X86 server. The X86 server has 4 standard network ports; performing double-network-card binding on every 2 network ports, and allocating an IP address; each X86 server has 2 IPs (4 portals). The X86 server is also called CISC (complex instruction set) architecture server or PC server (Personal Computer), which is a PC architecture based server using Intel or other processor chips compatible with the X86 instruction set. Has the advantages of low price, good compatibility and the like.
It should be noted that fig. 1a and fig. 1b are only schematic diagrams for illustrating connection relationships between devices in a communication service system, and a specific connection manner in practical application may be designed according to needs. The number of general servers can also be configured as desired, for example: two general servers can be added as communication service nodes Node-D, etc. It is also possible to reduce the common servers of one or more of the three nodes Node-A, Node-B and Node-C. Usually, two general servers are arranged for each additional node, wherein one general server is used as a host and the other general server is used as a standby, so as to increase the reliability of the communication service system.
In an embodiment of the present invention, the function server includes at least one of: the authentication server is used for carrying out authentication and log recording on the user equipment applying for network access; the charging server is used for generating a flow bill of the corresponding user equipment according to the network bill of the user equipment recorded by the PCRF; the policy server PCRF is used for recording the network ticket of the user equipment based on the configured policy execution and controlling the network access behavior of the user equipment, and the policy comprises charging and control policies based on the content and the region accessed by the user equipment; and the customer relationship management server CRM is used for carrying out customer relationship management and issuing a strategy to the strategy server.
For example, referring back to fig. 1b, constructing the virtual layer two tunneling protocol network server VLNS on the generic server can avoid using a dedicated access router LNS physical device, thereby effectively reducing the device cost. And when the capacity of the access router LNS needs to be increased, the resources of the general server are obtained and further configured, and redesign planning and connection of the physical architecture of each device in the communication service system are not needed.

In one embodiment of the invention, the general-purpose server is configured to have at least two physical IPs, and each physical IP is correspondingly configured with a plurality of virtual IPs. For example: the universal server is an X86 server, wherein one X86 physical IP address is 192.168.2.10 and 192.168.2.20, 5 virtual IPs corresponding to the physical IP address 192.168.2.10 are configured, and the virtual IPs are 192.168.2.11-192.168.2.15 respectively. The number of virtual IPs reserved for each physical IP of the general-purpose server is not limited to 5, and may be configured as needed, for example, 10 virtual IPs reserved for each physical IP of the general-purpose server may also be configured. Thereby, the function server can be better deployed on the general-purpose server.

The function servers can also be classified into a number of importance levels according to the importance of the network functions, for example: two levels VLNS are assigned a first importance level and the others are assigned a second importance level.
For example, each X86 server is assigned 2 physical IP addresses, each IP address reserving 10 IP addresses for IP configuration of network functions. For example: the X86 service IP addresses are 192.168.2.10 and 192.168.2.15, then the IP addresses of the following network devices are automatically assigned according to the following codes.
In operation 203, a mirror resource corresponding to the function server is acquired according to the function type.

And configuring the image resources corresponding to the deployed function servers acquired in the operation 203 to the corresponding target hosts.
For example, a general server of the communication service system adopts 3 groups of X86 servers, one X86 server in each group of X86 servers is used as a host machine, and the other is used as a standby machine. When the function type of the function server carried by the service node construction instruction of the function server includes the VLNS, the configuration resource of the X86 server and the VLNS image resource corresponding to the VLNS server are acquired according to the function type. Obtaining the configuration resources of the X86 server shows that the VLNS server can be configured to the first group of servers, and the virtual IP addresses are 192.168.2.11-192.168.2.14. Thus, the VLNS mirror resources are allocated to the X86 server hosts of group 1X 86 servers, and the VLNS servers are allocated with the corresponding virtual IP addresses as: 192.168.2.11 to 192.168.2.14, and completing the construction of the service node of the function server.
