Abstract
The invention discloses a GSM-R communication module for an integrated user identity module, which belongs to the field of railway communication devices. The module integrates hardware of an existing GSM-R communication module and the integrated user identity module and introduces an OTA technique to modify the information in the integrated user identity module. By adopting the GSM-R communication module, bad contact between an existing SIM card and the GAM-R communication module which results in the occurrence of communication interruption or a data transmission error due to vibration, temperature change and the like can be fundamentally avoided, and simultaneously, the management and maintenance are convenient for maintainers.
Description
Technical field
The present invention relates to the railway communication apparatus field, relate in particular to a kind of GSM-R communication module of module for integrated user identity.
Background technology
When second generation mobile communication system (GSM) occurred, a kind of new module-subscriber identification module (abbreviation SIM card) had also occurred.SIM card is placed in the special-purpose draw-in groove of GSM mobile communication module, is used to replace mobile communication module to store and the process user related data.When this SIM card was used in any GSM mobile communication module, user's information and setting were all available, and need not to change setting.
Along with second generation mobile communication system is applied to the railway business, i.e. GSM-R (GSM For RailWay).GSM-R and new feature thereof determined and need store new user related information in SIM card, for example organizes ID (GID), function number etc.Yet because the particularity of railway applications, in GSM-R used, the mobile communication module that SIM card is housed was placed on the train locomotive usually, the operational environment of relative public mobile communication, and working environment is more abominable; Vibration, temperature Change all can cause SIM card and the loose contact of GSM-R communication module, cause train-ground communication to interrupt or data transmission fault, have a strong impact on traffic safety and conevying efficiency.
Summary of the invention
The objective of the invention is to have proposed a kind of GSM-R communication module of module for integrated user identity at the problem affected by environment and loosening easily that contacts between SIM card in the present railway GSM-R system described in the background technology and the GSM-R mobile communication module.
It is characterized in that described module comprises: existing GSM-R communication module, module for integrated user identity and OTA module;
Wherein, existing GSM-R communication module and module for integrated user identity achieve a fixed connection by the circuit welding manner;
Described OTA module is embedded in the module for integrated user identity;
Described module also provides a RS232 type serial ports, is used for being connected with the SIM card card reader device.
The present invention has fundamentally avoided owing to reasons such as vibration, temperature Change cause existing SIM card and the loose contact of GSM-R communication module, so that the generation of the incident of communication disruption or data transmission fault, has also made things convenient for administering and maintaining of attendant simultaneously.
Description of drawings

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment is elaborated.Should be emphasized that following explanation only is exemplary, rather than in order to limit the scope of the invention and to use.
The GSM-R communication module of a kind of module for integrated user identity of the present invention comprises: have GSM-R communication module, module for integrated user identity and OTA module now, be depicted as the GSM-R communication module of module for integrated user identity in Fig. 1 frame of broken lines.
Module for integrated user identity is identical with existing GSM-R communication module with interface physical characteristic and existing separate type SIM card between the existing GSM-R communication module.Fix by draw-in groove between existing separate type SIM card and the existing GSM-R communication module.Between module for integrated user identity and the existing GSM-R communication module, formerly have a way of contact to achieve a fixed connection for the circuit welding manner by changing, communication protocol is constant between module for integrated user identity and the existing GSM-R communication module, observes existing standard.
The OTA module is embedded in the integrated form subscriber identification module.
The GSM-R communication module of module for integrated user identity provides the function of reading and writing SIM card information by the RS232 interface, and the SIM card card reader device is connected with the GSM-R communication module of module for integrated user identity by RS232 type serial ports;
The GSM-R communication module of module for integrated user identity is used on the rail transportation circuit that has the GSM-R digital mobile communication network to cover.Before using first, need write data by the SIM card card reader device, the modification of SIM configuration information afterwards realizes by the OTA technology.
The GSM-R communication module adopts the product of existing each manufacturer production, the integrated form subscriber identification module is observed the regulation of existing standard to it, the integrated circuit of core is continued to use the product of existing each manufacturer production, and the serial ports that increases RS232 is used for card reader device and carries out writing of SIM card configuration information when initialization.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and is familiar with those skilled in the art in the technical scope of the present invention's exposure; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
Claims (2)
