Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method and an apparatus for identifying a data card port attribute. BACKGROUND As a kind of Internet access product, a data card has been widely used due to its convenient portability. At present, there are two main ways to use data cards: Mode 1. The data service function is completed by the data card application on the host side; Mode 2, the data card acts as a server in the client/server system. In mode 1, the data service function includes a data card port identification function, and the data card port identification mainly includes: data card identification, data card entry multi-port mode recognition, and data card port attribute identification. In the prior art, the data card identification mainly obtains a device descriptor corresponding to the USB device by traversing the USB device on the USB bus, thereby obtaining a VID (vendor ID) and a PID (product ID), and determining whether to identify by the VID. After the data card is identified, the data card needs to enter the multi-port mode. Only in this mode, the corresponding port can be driven and recognized. The prior art is mainly completed by ejecting the optical disc; In the prior art, in the multi-port mode, the corresponding interface device file (ttyUSB* or ttyACM*) is generated by using the USB to serial port driver, and the AT command can be sent according to the AT and MODEM ports, and the AT command is sent to the interface device file one by one. And find the AT port and MODEM port from all ports according to the returned result. To distinguish between the AT port and the MODEM port, configure a configuration file for the AT port and the MODEM port respectively. This configuration file records the sequence in which the data card product finds the AT port and the MODEM port. However, this method requires the data card application to scan all the data card ports to find the AT and MODEM ports. It is not possible to know the corresponding port attributes when the data card application works, thereby delaying the data card online time. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a method and apparatus for identifying data port attributes to solve at least one of the above problems. According to an aspect of the present invention, a method for identifying a data card port attribute is provided, including: acquiring identification information of each port of a currently inserted or restarted data card; and calling a matching rule for the data card according to the identification information of each port The port attributes of each port are identified. The matching rules include: Correspondence between the port attribute of the port and the identifier of the port. Before obtaining the identification information of each port of the currently inserted or restarted data card, the method further includes: obtaining an identifier of all ports of the data card; generating a matching rule, and recording, between the identifiers of the ports and the port attributes of the port, in the matching rule Correspondence. Obtaining the identifiers of all ports of the data card, including: obtaining port attribute distribution information of all ports of the data card; determining the identifiers of each port in all ports according to the port attribute distribution information. The attribute distribution information includes: the manufacturer number of the data card, the product number of the data card, the type of the port, and the location information of the port on the data card. Generate matching rules, including: Generate port name information for each port of all ports of the data card. After identifying the port attributes of the ports of the data card according to the identification information of the ports, the method further includes: recording port attribute information of each port of the current data card.
