Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to a communication method and device, electronic equipment and storage medium. BACKGROUND

[0002] Due to the development of Internet of Things technology, it is necessary to establish multiple parallel packet switch (PS) connections on a terminal. The quality of service (QoS) parameters and the target network accessed by these PS connections can be different. Among them, the PS connection and the packet data protocol (PDP) can be one-to-one. That is, a terminal can have multiple PDP contexts, and there can be multiple different QoS profiles at the same time.

[0003] In the prior art, before establishing a PDU connection, the module determines the current multi-dialing mode by the value of the current usbmode. For example, if the current usbmode is 18 or 23, it is considered that the current multi-dialing mode is ECM multi-dialing, wherein ECM multi-dialing is one of USB multi-dialing; if the current usbmode is 32 or 17, it is considered that the current multi-dialing mode is RGMII multi-dialing.

[0004] However, in many actual situations, the module needs to be connected to the host computer through the universal serial bus (USB) port and the reduced gigabit media independent interface (RGMII) at the same time to perform multi-dialing data services. In the prior art, the usbmode value cannot be modified in real time (modifying the usbmode module will restart) during multi-dialing, and only one of USB multi-dialing or RGMII multi-dialing can be supported.

[0047] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0048] In order to solve the problem that the tragedy occurs because the rescue measures cannot be taken in time after the vehicle falls into water, the present application provides a communication method applied to a mobile device management module which can be located in a module. As shown in the figure, Figure 1 In an embodiment of the present application, the communication method comprises steps 101-103:

[0049] Step 101: receiving a first AT instruction and a second AT instruction sent by a mobile device.

[0050] Specifically, the mobile device sends the first AT instruction and the second AT instruction to the mobile device management module.

[0051] Among them, the number of the first AT instruction can be at least one. Similarly, the number of the second AT instruction can also be at least one.

[0052] More specifically, the mobile device is connected with the mobile device management module through its USB interface and RGMII interface, and sends the first AT instruction and the second AT instruction to the mobile device management module through the USB interface and the RGMII interface.

[0053] Step 102: performing data dialing based on the first AT instruction.

[0054] Among them, the first AT instruction includes a first enable flag and the identification of at least one WAN port.

[0055] Specifically, when performing data dialing based on the first AT instruction, if the first enable flag is 1, then based on the first enable flag, the at least one WAN port is activated, and the PDU connection is established using the activated WAN port. That is, when the first enable flag is 1, the WAN port corresponding to the identification of the WAN port in the first AT instruction where the first enable flag is located is activated.

[0056] Correspondingly, if the first enable flag is 0, then based on the first enable flag, the at least one WAN port is deactivated. That is, when the first enable flag is 0, the WAN port corresponding to the identification of the WAN port in the first AT instruction where the first enable flag is located is deactivated.

[0057] Generally, the number of WAN ports to be activated by the first AT instruction can be default or determined based on actual needs of the mobile device.

[0058] More specifically, when establishing the PDU, the PDU connection can be established based on different CIDs (i.e. the identification of the PDP context).

[0059] For example, one PDU connection is established for each PDP context.

[0060] In another possible embodiment, the number of first AT instructions is at least one. One first AT instruction includes a first enable flag and the identification of one WAN port. By one first AT instruction, the WAN port corresponding to the identification of the WAN port included in the first AT instruction is activated.

[0061] In another possible embodiment, the first AT instruction can only include the first enable flag. If the first enable flag is 1, the default number of WAN ports are activated based on the first enable flag. Correspondingly, if the first enable flag is 0, the default number of WAN ports (or all WAN ports) are deactivated based on the first enable flag.

[0062] For example, in a three-way dialing, by the first AT instruction, WAN1, WAN2 and WAN3 are activated, i.e. WAN1 port, WAN2 port and WAN3 port are activated. At this time, the base station can be communicated with by the activated WAN1 port, WAN2 port and WAN3 port.

[0063] Specifically, the first AT instruction activates the corresponding WAN port by calling the GTDAIL tool. Correspondingly, the GTDAIL tool can also be called to deactivate the corresponding WAN port.

[0064] For example, the first AT instruction can be AT+GTDAIL=1. The 1 indicates activation. At this time, by the first AT instruction, all WAN ports corresponding to the multi-way dialing are activated, and the PDU connection is established by using the activated WAN ports.

[0065] For example, the first AT instruction can be AT+GTDAIL=1,1. The first 1 is the first enable flag, indicating activation. The second 1 is the identification of the WAN port, indicating WAN1 port. At this time, by the first AT instruction, WAN1 port is activated, and the PDU connection is established by using the activated WAN1 port.

[0066] Step 103: binding the target LAN port and the target WAN port based on the second AT instruction.

[0067] The target LAN port is a USB interface or an RGMII interface.

[0068] In addition, the second AT instruction includes a second enable flag, a type of the target LAN port, an identification of a target VLAN, and an identification of a target WAN port. The type of the target LAN port includes a USB interface or an RGMII interface, and the target WAN port is any one of the activated WAN ports.

[0069] Specifically, the target LAN port is determined based on the type of the target LAN port. Then, if the second enable flag is 1, the data of the target VLAN of the target LAN port is bound to the target WAN port based on the second enable flag, the identification of the target VLAN, and the identification of the target WAN port. Correspondingly, if the second enable flag is 0, the data of the target VLAN of the target LAN port is unbound from the target WAN port based on the second enable flag, the identification of the target VLAN, and the identification of the target WAN port.

[0070] More specifically, if the type of the target LAN port is a USB interface, the target LAN port is determined as a default USB interface, and if the type of the target LAN port is an RGMII interface, the target LAN port is determined as a default RGMII interface.

[0071] The default USB interface is a USB interface connected to the mobile device management module in the mobile device, and similarly, the default RGMII interface is an RGMII interface connected to the mobile device management module in the mobile device.

[0072] For example, the identification of the default USB interface can be usb0, and the identification of the default RGMII interface can be eth0.

[0073] More specifically, the second AT instruction binds the target LAN port and the target WAN port by calling the GTLANCFG tool. Correspondingly, the second AT instruction can also unbind the target LAN port and the target WAN port by calling the GTLANCFG tool.

[0074] For example, the second AT instruction is AT+GTLANCFG=1, 0, 2, 3. Here, 1 is the second flag, indicating binding, 0 is the type of the target LAN port, indicating that the type of the target LAN port is a USB interface, 2 is the identification of the VLAN, indicating VLAN2, and 3 is the identification of the target WAN port, indicating WAN3 port. At this time, the data of VLAN2 of the default USB interface, such as usb0, is bound to WAN3 port through the second AT instruction.

[0075] For example, the second AT instruction is AT+GTLANCFG=0,0,2,3. Wherein, 0 is the second flag bit, indicating unbinding, 0 is the type of the target LAN port, indicating that the type of the target LAN port is USB interface, 2 is the identification of the VLAN, indicating VLAN2, and 3 is the identification of the target WAN port, indicating WAN3 port. At this time, through the second AT instruction, the data of VLAN2 of the default USB interface, for example, usb0, is unbound from WAN3 port.

[0076] It can be understood that the binding or unbinding is performed on the up / down LAN side network card (or LAN port) inside the module, so as to realize the flexible configuration between the LAN port and the WAN port.

[0077] It should be noted that through the above process, for the multi-scene application on the mobile device, the mobile device management module can perform data dialing and interface binding based on the first AT instruction and the second AT instruction received from the mobile device, that is, binding the target WAN port and the USB interface / RGMII interface as the target LAN port. In this way, the LAN port and the WAN port can be flexibly and dynamically configured, and the mobile device can support data services from the USB interface while supporting data services from the RGMII interface when performing multi-dialing.

[0078] In addition, by using different AT instructions to perform data dialing and interface binding operations respectively, unnecessary association between data dialing and interface binding can be reduced.

[0079] In another possible embodiment, after binding the data of the target VLAN of the target LAN port to the target WAN port, an interface of the target VLAN is added under the target LAN port, and the interface of the target VLAN is bound to the target WAN port.

[0080] For example, by using ip link add link eth0 name eth0.1 type vlan id 1, an interface eth0.1 of VLAN1 is added under the RGMII interface eth0, and based on the binding of the VLAN1 data of eth0 to the WAN2 port, eth0.1 is bound to the WAN2 port, so that the data of eth0.1 is sent out through the WAN2 port.

[0081] Through the above process, the interface of the VLAN is added under the target LAN port, and the added interface of the VLAN is bound to the target WAN port, so that the VLAN interfaces under each LAN interface are flexibly distributed to the corresponding WAN port, and the flexible dynamic configuration between the VLAN data under the LAN port and the WAN port is realized.

[0082] In another possible implementation, after adding the interface of the target VLAN and binding the interface of the target VLAN with the target WAN port, the mobile device management module creates a bridge for communication between the interface of the target VLAN and the target WAN port, and allocates an intranet address for the target VLAN based on the bridge, and then converts the intranet address in data of the target VLAN into an extranet address, so as to send the data of the target VLAN to the base station through the target WAN port by using the extranet address. That is, the extranet address is used to send the data of the VLAN to the base station through the WAN port.

[0083] Specifically, after the bridge is established, the dnsmasq process is started based on the bridge to allocate an address to the corresponding VLAN in the mobile device. The address allocated to the corresponding VLAN in the mobile device is an intranet address.

[0084] Since the address (IP network segment) allocated to the mobile device by the mobile device management module is an intranet address starting with 192.168, only the forwarding function is enabled and the routing table is configured, and the communication between the intranet and the extranet cannot be realized. In order to solve this problem, the network address translation (NAT) technology of iptables can be used to perform network address translation, and convert the intranet address allocated to the corresponding VLAN in the mobile device into an extranet address.

[0085] For example, the intranet address of the VLAN can be converted to obtain the extranet address of the VLAN by using the iptables-t nat (table)-A POSTROUTING (transition chain)-o wanX-j MASQUERADE (address masquerade)-random command.

[0086] It can be understood that the binding or unbinding adds or removes the corresponding LAN side network card in the module to the corresponding bridge, so as to realize the flexible configuration between the LAN port and the WAN port.

[0087] For example, the mobile device sends a plurality of first AT instructions to perform data dialing, so as to activate the corresponding WAN port and establish a PDU connection. The plurality of first AT instructions are AT+GTRDAIL=1,1, AT+GTRDAIL=1,2, and AT+GTRDAIL=1,3. The AT+GTRDAIL=1,1 is used to activate the WAN1 port, the AT+GTRDAIL=1,1 is used to activate the WAN2 port, and the AT+GTRDAIL=1,3 is used to activate the WAN3 port. After the WAN1 port-WAN3 port is activated, the PDU connection is established by using the activated WAN1 port-WAN3 port.

[0088] For example, the mobile device sends a plurality of second AT commands to perform interface binding, i.e., binding the external data interface (LAN port) and the WAN port. The format of the second AT commands can be, for example, AT+GTLANCFG= <enable> , <type> , <vlanid> , <wanid>Wherein, enable is a second enable flag, 1 represents binding, and 0 represents unbinding; type is the type of the LAN port, 0 represents a USB interface, and 1 represents an RGMII interface; vlanid is the identification of the LAN side VLAN; and wanid is the identification of the WAN port.

[0089] Exemplarily, the plurality of second AT instructions can be AT+GTLANCFG=1, 0, 0, 3 and AT+GTLANCFG=1, 1, 1, 2. Wherein, AT+GTLANCFG=1, 0, 0, 3 is used for binding the data of the non-VLAN of the USB port and the WAN3 port, and AT+GTLANCFG=1, 1, 1, 2 is used for binding the data of VLAN1 of the USB port and the WAN2 port.

[0090] Exemplarily, after receiving the plurality of second AT instructions, the parameter information of the VLAN is configured on the host computer. A new VLAN1 interface, i.e. eth0.1 interface, is added under the actual eth0 interface through iplink add link eth0 name eth0.1 type vlan id 1. At this time, the binding of eth0.1 and the WAN2 port is realized, so that the data of eth0.1, i.e. the data of VLAN1, is transmitted out through the WAN2 port (i.e. to the base station).

[0091] Exemplarily, as shown in Figure 2 , the present application is mainly applied to Figure 2 a communication system. The communication system includes a mobile device, a mobile device management module (MDM) and a base station.

[0092] Wherein, the mobile device is connected with the mobile device management module through its AT port, and the mobile device management module communicates with the base station through a public data network (PDN).

[0093] Specifically, the mobile device supports USB multi-dialing and also supports RGMII multi-dialing.

[0094] Specifically, the mobile device includes a plurality of AT ports, and the plurality of AT ports include actual ports such as usb0 and eth0. The usb0 port is further divided or increased with VLAN usb ports such as usb0.1 and usb0.2, and the eth port is further divided or increased with VLAN eth ports such as eth0.1 and eth0.2.

[0095] The mobile device is used to send a first AT instruction and a second AT instruction, i.e., AT+GTDAIL instruction and AT+GTLANCFG instruction, to the mobile device management module.

[0096] Specifically, the mobile device management module further comprises a local area network management (LAN-MGR) submodule and a data call (DATACALL) submodule.

[0097] The data call submodule activates different WAN ports and establishes PDU connections by using different APN technologies, such as default PDN technology or on demand technology, based on the received first AT instruction. Figure 2 As shown in the figure, WAN1 port is activated by using default PDN technology, WAN2 port and WAN3 port are activated by using on demand technology, and PDU connections are established, WAN1 port connects the base station through PDN1, WAN2 port connects the base station through PDN2, and WAN3 port connects the base station through PDN3.

[0098] Specifically, the LAN-MGR submodule binds / unbinds the VLAN interface under the LAN port, such as USB interface or RGMII interface, with WAN based on the received second AT instruction. Figure 2 As shown in the figure, the data of VLAN1 of the USB interface is bound with WAN1 port (or WAN1 dialing), the data of non-VLAN of the USB interface is bound with WAN3 port (or WAN3 dialing), the data of VLAN1 of the RGMII interface (i.e., eth interface) is bound with WAN2 port (or WAN2 dialing), and the data of VLAN2 of the RGMII interface is bound with WAN3 port (or WAN3 dialing).

[0099] Specifically, as shown in the figure, the LAN-MGR submodule establishes bridges bridge0, bridge1 and bridge2 between the LAN-MGR submodule and the mobile device. Figure 2
