Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 2 is a schematic structural diagram of a wireless module device without a host according to an embodiment of the present invention, which includes a wireless interface processing unit 201 and a module host processing unit 202;
a wireless interface processing unit 201, providing a wireless communication protocol interface, connected to the wireless base station 200 through the wireless communication protocol interface, and configured to forward an IP address setting instruction sent by the wireless base station 200 to the module host processing unit 202 when establishing a wireless connection with the wireless base station 200;
and the module host processing unit 202 is connected with the wireless interface processing unit 201 through a wireless MAC link protocol, and is configured to acquire a public network IP address in the IP address setting instruction, and perform data interaction with the host device 203 through the public network IP address. In a specific application, when the wireless base station, the wireless module device without a host and the host device need to establish a connection, the wireless base station 200 may allocate a public network IP address to the wireless module device without a host, generate an IP address setting instruction according to the allocated public network IP address to the wireless module device without a host, after receiving the IP address setting instruction, the wireless interface processing unit in the wireless module device without a host forwards the IP address setting instruction to the module host processing unit through a wireless MAC link protocol, and the module host processing unit obtains the public network IP address in the IP address setting instruction and performs data interaction with the host device through the public network IP address.
Specifically, the module host processing unit 202 provides a plurality of IP network interfaces, each of which can perform data interaction with the host device 203 through a public network IP address allocated by the wireless base station 200 using a standard IP network protocol. The IP network interface includes a USB interface and an ethernet interface, and the module host processing unit 202 and the host device 203 can implement physical layer connection through the USB interface or the ethernet interface.
Specifically, module host processing unit 202 shares the same public network IP address with host device 203 through a port. The module host processing unit 202 receives an operation instruction of an external system through the module management port, where the operation instruction includes an upgrade instruction, a query instruction, and a management instruction.
Specifically, when the module Host processing unit 202 is in the routing mode, the Host device 203 acquires a private network IP address through a DHCP (Dynamic Host Configuration Protocol), and performs work according to the private network IP address. The network interface where the module host processing unit 202 and the host device 203 are connected is provided with a private network IP address, and the module host processing unit 202 performs local communication with the host device 203 through the private network IP address. The module host processing unit 202 allocates the public network IP address allocated by the wireless base station 200 to the host device 203 through a Dynamic Host Configuration Protocol (DHCP) service when it is set to the bridge mode. When the wireless module device without a host reestablishes a connection with the wireless base station 200, the wireless module device without a host detects whether the public network IP address in the IP address setting instruction sent by the wireless base station 200 changes, and if so, resets the IP network interface connected to the host device 203, so that the host device 203 acquires the changed public network IP address according to a Dynamic Host Configuration Protocol (DHCP).
In a specific application, the wireless base station 200 and the wireless interface processing unit 201 interface through a wireless communication protocol, and perform data transmission by using a wireless air interface protocol, where the wireless air interface protocol may use an existing 4G LTE or a future 5G wireless protocol, and the wireless interface processing unit 201 operates in a wireless link layer protocol (a two-layer network protocol).
And the wireless interface processing unit 201 is connected with the module host processing unit 202. The module host processing unit 202 and the wireless interface processing unit 201 perform a wireless MAC link communication protocol for data interaction, thereby completing three-layer IP network communication between the wireless base station 200 and the module host processing unit 202, and the module host processing unit 202 is to be assigned with a corresponding network IP address, and has functions of DHCP service, bridging, routing forwarding, and the like. In addition to the IP address assigned by the wireless base station 200, the network interface of the module host processing unit 202 and the host device 203 will set a private network IP address for local communication with the host device 203.
The module host processing unit 202 communicates with the host device 203, and is interfaced using a standard IP network protocol, and the physical layer connection may be a USB interface or an ethernet interface. If the wireless module device without the host operates in the routing mode, the host device 203 can obtain the private IP address through DHCP to operate. If the wireless module device without a host is operating in bridge mode, module host processing unit 202 will configure the DHCP service and will assign the host device a public network IP address assigned by wireless base station 200. If necessary, the module host processing unit 202 can use the network-allocated public network IP address in common with the host device 203 by sharing the port, while the module host processing unit 202 can use only the module management port, and the other ports are used by the host device 203.
Since the module host processing unit 202 adopts a general IP network interface manner and can use the module management port to complete the management and upgrade functions of the wireless module device without a host, the application of the wireless network of the host device 203 is not affected at all. Because the host device 203 does not need to upgrade the wireless module device without the host and manage the two-layer interface, the modules provided by various manufacturers can completely realize self-management, perform different operator services and management settings, realize the function of a module firewall, and ensure the safety and the universality of the host device 203.
In practical applications, the wireless module device without a host has a function of self-management through an external system, but does not exclude or prevent the host device 203 from managing the wireless module device without a host, and the host device 203 can still use a standard IP protocol-based universal interface specification to query, upgrade or set up and manage the wireless module device without a host through a private IP address of the wireless module device without a host.
In addition, since the wireless data filtering and forwarding can be implemented by the module host processing unit 202 instead, the processing overhead of the host device 203 is greatly reduced, so that the performance of other applications on the host device 203 can be better exerted.
The embodiment of the invention greatly simplifies the realization of the wireless module device without a host and the interface of the host equipment, and is convenient for the unification and standardization of the wireless interface of the host equipment. Based on the IP three-layer interface, the network security guarantee of the host side can be better realized, different operator applications can also directly manage the wireless module device without the host through an air interface protocol, and the host equipment does not need to participate in the management of the wireless module device without the host according to the condition. The operator can also realize different QOS and firewall management functions through the configuration of the wireless module device without the host, the wireless module device is transparent to the host equipment, the work of the wireless module device without the host does not depend on the host equipment any more, namely, the wireless module device without the host can realize a no-host mode, when the bridging working mode is adopted, the wireless module device can realize the same effect as the existing MODEM wireless module, and shares a network IP address with the host equipment.
The wireless module device without the host machine in the embodiment of the invention adopts the standard three-layer IP network interface to be in communication connection with the host machine equipment, thereby greatly simplifying the complexity of the host machine equipment for supporting different module interfaces and being well compatible with the module types of different manufacturers and operators. The wireless module device and the host equipment which do not need the host can share the IP Address distributed by the same 1 Network to work, or work in a routing NAT (Network Address Translation) mode, the work of the wireless module device which does not need the host does not depend on the host equipment any more, the remote and self-management functions of the wireless module device which does not need the host can be realized, partial Network firewall and service management functions can be completed, the processing cost of the host equipment is greatly reduced, and the performance of the host is improved.
