Description

 POS terminal and network configuration method and system thereof

 Technical field

 The present invention relates to the field of communications, and in particular, to a POS terminal and a network configuration method and system thereof.

 Background technique

 With the widespread use of POS terminals, their application environments are becoming more widespread from banking systems to third-party payment environments. Regardless of the application environment, POS Secure and fast communication between the terminal and the background host becomes one of the essential steps. For example, currently mobile terminals usually pass 2G/3G The network communicates with the background host. However, considering some application environments from the perspective of financial security, it is necessary to build a private network. Therefore, there are inevitably differences in the network environment in different application environments.

 When the POS terminal adopts 2G/3G communication methods such as GPRS, WCDMA, EVDO, etc., POS is required. After the terminal accesses the wireless network, the subsequent transaction process can be performed. The above communication method uses the PPP protocol at the link layer, according to the RFC. It is stipulated that at the beginning of communication, some communication parameters of the two parties can be agreed upon through negotiation and guarantee the follow-up communication process. The PPP protocol provides commonly used negotiable parameters ( Options ), and allows customers to modify the negotiation parameters to adapt to various network environments.

 However, mobile terminals that currently support wireless Internet access, such as various smart phones, are performing PPP. When dialing, the process of establishing a link is adopted by using a curing parameter, that is, the relevant negotiation parameters are solidified in the dialing script in order to adapt to the public network environment. Therefore, when the terminal is developed, the configuration of the dial-up Internet connection can be successfully performed. Adapted to subsequent use, did not consider the scalability of the negotiation parameters.

 The application environment of the POS terminal is different from that of the civilian mobile phone customer. For security reasons, POS In most cases, the terminal needs to run in a private network environment. Therefore, when the same POS terminal uses different private network environments, communication failure occurs due to incompatibility of communication parameters, and the same POS The terminal may need to be used in different network environments. The hardened dialing script may cause communication failure. You need to refresh different firmware for different environments, even using different POS terminals. This greatly increases the POS. Use and maintenance costs. Usually software upgrades require the use of a PC, a dedicated download line, a dedicated download program, and the re-development of the firmware costs a certain amount of labor.

 detailed description

 The detailed description of the technical contents, structural features, and the objects and effects of the present invention will be described in detail below with reference to the accompanying drawings.

 Please refer to FIG. 1 , which is a structural block diagram of a POS terminal network configuration system according to the present invention. The POS terminal network configuration system 100 The configuration file generating unit 11, the configuration file installation unit 12, the configuration file selection unit 13, the negotiation parameter extraction unit 14, and the negotiation communication unit 15 are included.

 According to the RFC regulations, at the beginning of the communication, some of the communication parameters of the two parties can be agreed upon through negotiation and guarantee the follow-up communication process. When POS When the terminal adopts 2G/3G communication methods such as GPRS, WCDMA, EVDO, etc., POS is required. After the terminal accesses the wireless network, the subsequent transaction process can be performed. The above communication method uses the PPP protocol at the link layer, and the PPP protocol provides common negotiation parameters ( Options ), and allows customers to modify the negotiation parameters to adapt to various network environments.

 The profile generating unit 11 It is used to obtain a negotiation parameter value and generate a plurality of configuration files in a permutation and combination manner. Where each profile uniquely corresponds to one profile ID . The negotiation parameters include character escaping processing parameters, authentication mode, number of LCP packet retransmissions, LCP packet retransmission interval, compression algorithm, address, and DNS acquisition path.

 LCP for PPP communication according to RFC regulations The negotiation phase is mainly used to determine the processing methods for subsequent communication between the two parties, such as authentication method and character escaping processing. The configuration file is a combination of negotiation parameters corresponding to the processing methods.

 Please refer to Figure 2, which is a schematic diagram of a configuration file. The configuration file will be described in conjunction with Figure 2.

 For example, add the compression algorithm parameter 'novj ', ' novjccomp ', ' nopcomp ', ' in the negotiation parameters. When the noccp 'option is used, it means that vj, vjccomp, pcomp, ccp are not used during negotiation. These compression algorithms; when there is no such option, it means that these compression algorithms are supported by default. Whether to use the compression algorithm is determined by the peer.

 For another example, when the address parameter 'noipdefault' is added to the negotiation parameter, it means that no IP address is specified. Assigned by the peer. When the DNS acquisition path parameter 'usepeerdns' is added to the negotiation parameters, it indicates that the DNS address used in the subsequent communication process is specified by the peer.

 For example, when the LCP packet retransmission interval parameter ' lcp-echo-interval 30 ' is added to the negotiation parameter, The interval for retransmission of LCP packets is 30s. If not set, the LCP packet retransmission operation is not performed. The LCP packet retransmission interval parameter is added to the negotiation parameters. lcp-echo-failure 3 ' indicates that the number of LCP packets allowed to be retransmitted is 3 times.

The selection and setting of the negotiation parameter values are summarized according to the cases encountered in the local use. For example, when used in a certain area of Jiangxi, the configuration of the opposite router needs to be compatible with the local broadband network, so the router configuration cannot be modified. And after testing and verification, it is happening During the PPP negotiation process, the server side requires the POS terminal to escape all the control characters during PPP negotiation because of the packet parsing mechanism. That is, the character escaping processing parameter 'asyncmap' is required. 'Set to 0xFFFFFFFF for normal data transfer. Therefore, we will use the character escape processing parameter 'asyncmap' as one of the negotiation parameters in the configuration file, and will be ' The values of asyncmap ' are set to the commonly used FFFFFFFF, A0000, 0;

You can adjust the configuration file selection to suit different network link requirements before conducting communication negotiation. This can quickly troubleshoot the problem, even if the preset configuration file is still not enough to adapt to the current network environment, you can also form a new configuration file, download it to the secure way. In the POS terminal. Since only a few configuration parameters are set in the configuration file, the file size is only within one hundred bytes, which is usually K-byte or even M-byte compared to the entire firmware, which saves a lot of time.

 The profile installation unit 12 is configured to install the profile in a POS terminal secure storage area.

 The profile selection unit 13 is configured to select a profile ID according to the selection input . Specifically, the selection input is generated by an input device, which may be a mechanical input device such as a touch screen or a button.

 The negotiation parameter extraction unit 14 is configured to read the selected profile ID from the secure storage area. Corresponding configuration file, extract the negotiation parameter value in the configuration file. For example, when the network fails, the administrator enters the profile selection interface and enters the profile ID. The corresponding configuration file can be selected, or the configuration file selection interface displays multiple configuration file IDs for the administrator to select.

 The negotiating communication unit 15 is configured to perform communication negotiation according to the extracted negotiation parameter value and establish a communication link according to the communication negotiation result.
