Problems solved by technology

[0003] At present, in the CBTC system, the usual way to switch between the main train segment and the test run segment is to power off the CPE, replace the SIM (Subscriber Identity Module) card, power on the CPE again, attach the CPE to the network, and access the network; the whole process The operation is more complicated and cumbersome, and the requirements for operators are relatively high, and the whole process takes a long time

Embodiment Construction

[0020] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0021] The present invention provides a method for CPE switching between the train section and the test section. The CPE is designed with dual SIM cards. The SIM cards register different information in the EPC (Evolved Packet Core, Evolved Packet Core Network) and are assigned different IP addresses. The network IPs of the main train section and the test run section are isolated on the network to avoid mutual interference and influence. The detailed implementation method is further described below.

[0022] see figure 1 , the scheme of the embodiment of the present invention is as follows:

[0023] Two SIM card modules are set on the CPE equipment, which are independent of each other and can switch circuits, which are respectively denoted as SIM1 and SIM2.

[0024] The LTE baseband signal processing module, referred to as the LTE module...

Abstract

The invention discloses a CBTC inter-section CPE switching method and system and relates to a rail transit client device. CPE is provided with two SIMs, wherein the SIMs are associated with different IP address information. The method is characterized by, when the CPE switches from a trial section to an ahead section, or switches from the ahead section to the trial section, turning on an SIM mode switching switch of the CPE to power off the current LTE module, and then, switching to the other SIM; and finally, powering on the LTE module again and carrying out network attachment. The method and system can greatly reduce complexity in switching between the ahead section and trial section of the CPE, and reduce switching process time; the physical isolation is higher; safety is high; and the method and system have an important market value.

Description

technical field [0001] The invention belongs to the communication field, and relates to a CPE (Customer Premises Equipment, Customer Premises Equipment, client device) handover technical solution. Background technique [0002] In order to combine with the mainstream communication system and have a larger communication bandwidth, the current CBTC system is increasingly adopting the LTE communication system. As a client device, CPE is responsible for providing service access in the CBTC system. In the rail communication system, in order to perform system testing, installation and commissioning, etc., the main train section and the test run section are designed. The main train section and the test run section have The same spectrum resources, but different coverage areas, and the network isolation between the main train section and the test run section is required to avoid mutual influence. [0003] At present, in the CBTC system, the usual way to switch between the main trai...
