Problems solved by technology

The existing integrated routing and forwarding mechanism in the mobile Internet of Things does not consider the current mobile communication network status and the priority level of information to be sent, which will easily cause a large amount of sudden sensor network business data to impact the mobile communication network and affect the stability of the mobile communication network characteristics, even cause the communication network to be paralyzed, and the quality of service of the mobile communication network cannot be guaranteed

Embodiment 1

[0045] The router receives data to be transmitted from sensor networks of different service types, namely fire alarm, temperature detection, and humidity detection, and the priority is marked as A, C, and C. The resource scheduling processing module stores the data to be transmitted into different priority caches according to the priority, and stores the temperature detection and humidity detection data with the same priority into the same priority cache according to the order of arrival time. The data transmission of the data to be transmitted by the router is (here, it is assumed that the router access registration process has been completed, and the behavior of the mobile communication network including the RNC (Radio Network Controller) is replaced by the behavior of the coverage base station, for a simple description, embodiment 2- 4 same):

Embodiment 2

[0048] The router receives data to be transmitted from sensor networks of different service types, namely temperature detection and humidity detection, and their priority marks are C and C. The resource scheduling processing module of the router transmits the query information request (with the priority identification of the data to be sent in the request) to the coverage base station. The coverage base station detects that the current network is congested, and the priority of the sensor service data in the request is lower than that of other service data in the current network. Priority (for voice services, priority is B), then the coverage base station returns a data transmission rejection message to the router, and the router resends the transmission query information request after waiting time T, waits for the base station to respond, and then executes the response action.

Embodiment 3

[0050] The resource scheduling processing module of the router sends a transmission query information request (with the priority label of the data to be sent in the request) to the coverage base station. The coverage base station detects that the current network is congested, but the priority of the service type in the request is A, which is higher than the current network Priority of other business data in the network, the overlay base station disconnects the service connection with the lowest priority in the current network, and returns the data transmission approval information (the feedback information contains the priority identification of data transmission allowed), and then the router establishes a connection with the overlay base station Connection, the resource scheduling processing module completes the transmission of the fire alarm data whose priority is A according to the priority number in the information returned by the base station. For other data that has not b...

Abstract

The invention discloses a data transmission method and a system capable of fusing a router in a mobile internet of things. The method includes that priority parameters are added in network convergence information of wireless sensors of different business types and sent to a router which includes that a wireless sensor network is connected into a mobile communication network, the router and a wireless network controller conduct data transmission inquiring and interaction through a covering base station, and the router which feeds back information based on the wireless network controller sequentially sends information of different priority levels to the covering base station according to a preset resource scheduling method. The invention further discloses a data transmission system which corresponds to the method. Application of the data transmission method and the system can avoid the phenomenon that a large amount of gusty sensor network business data causes impact on the mobile communication network, stability of the mobile communication network is influenced, and even overall paralysis of the communication network is caused, guarantee service quality of the mobile communication network, and give consideration of information safety of the mobile communication network and the wireless sensor network.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a data transmission method and system for integrating routers in the mobile internet of things. Background technique [0002] Wireless sensor networks have brought about a revolution in the field of information perception, and the integration of wireless sensor networks and mobile communication networks has promoted the rapid development of mobile Internet of Things. Due to the variety of business types and application scenarios supported by wireless sensor networks, the information data is characterized by large amounts, bursts, and different priorities. The existing integrated routing and forwarding mechanism in the mobile Internet of Things does not consider the current mobile communication network status and the priority level of the information to be sent, which will easily cause a large amount of sudden sensor network business data to impact the mobile comm...
