Problems solved by technology

[0003] The radio resource control of the existing EC-GSM-IoT, LTE-M and NB-IoT three cellular IoT technology solutions is also configured based on inherent parameters. In actual deployment, equipment manufacturers and operators perform Parameter configuration, parameters do not have dynamic variability during operation, cannot be personalized according to actual business conditions, cannot meet the diverse business needs of IoT terminals, and do not have the ability to dynamically manage terminals in the network
As a result, a large waste of wireless resources is generated, resulting in low overall operational efficiency of the actually deployed cellular IoT

Embodiment 1

[0042] like figure 2 As shown, in this embodiment, the radio resource control method of the cellular Internet of Things includes the following steps:

[0043] Step S101, after the terminal of the cellular Internet of Things is connected to the access network device, the access network device obtains the context information of the terminal in real time, the context information includes the connection context and the service context, wherein the connection context usually includes the following information: UE type, The identification information of the UE, the preference of the user plane or the control plane to transmit data, the information of the established bearer, the current connection state, and the parameter configuration of the connection state management; the service context usually includes the time of terminal data transmission and reception, the size of the data packet, the Transmission direction, service delay requirements, and service priority.

[0044] Step S1...

Embodiment 2

[0057] This embodiment is a preferred solution of the present invention. On the basis of Embodiment 1, new connection requests in the network can be managed based on free resources in the network, and resource allocation between new access terminals and connected terminals can be coordinated. The specific process is as image 3 and Figure 4 shown.

[0058] When an idle terminal in the cellular Internet of Things requests to establish or resume a connection, if there are free resources in the network, the access network device will establish or restore the connection for the terminal, such as image 3 Shown:

[0059] Step S201, the UE is in an idle state and has no business data transmission. When the UE has new data to send to the access network device or periodically monitors paging messages, it will send an RRC connection establishment / restoration request message to the access network device.

[0060] Step S202, the UE sends an RRC connection establishment / restoration re...

Embodiment 3

[0069] This embodiment is a preferred solution of the present invention. On the basis of Embodiment 1 or Embodiment 2, resources allocated to low-priority terminals in the network can be adjusted based on resource conditions in the network and service characteristics of the terminals. like Figure 5 As shown, the specific steps are as follows:

[0070] Step S401, the access network device monitors the resource usage status in the network. When the resources in the network are used too much and the remaining available resources cannot meet the demand for the number of new connections expected to be added in this period of time under normal circumstances, a network resource warning occurs. Otherwise, the network resource is considered The remaining available resources can meet the needs of UEs expected to access during this period, and the network resources are normal.

[0071] Step S402, when the network resource warning occurs, the access network device obtains the context in...

Abstract

The invention discloses a wireless resource control method of a cellular Internet of Things, which comprises the following steps: after a terminal of the cellular Internet of Things is connected withaccess network equipment, the access network equipment acquires context information of the terminal in real time, and analyzes the context information to acquire service characteristics of the terminal; the access network equipment configures the corresponding connection configuration parameters according to the service characteristics so as to reduce the time delay of waiting for sending after the data service of the terminal is generated and reduce the time of the terminal in a connection service-free state; the access network device sends the configuration result to the terminal through theRRC message; after receiving the RRC message, the terminal executes corresponding configuration and performs Internet of Things service data transmission based on a configuration result; and after each transmission is completed, the access network equipment updates the context information of the terminal. The service characteristics of the Internet of Things terminal can be analyzed, the terminalis configured to enter the connection management mode corresponding to the service mode according to the service characteristics, and diversified Internet of Things service requirements are met.

Description

technical field [0001] The invention relates to a radio resource control (Radio Resource Control, RRC) method and system of the cellular internet of things, belonging to the technical field of wireless communication. Background technique [0002] As the control center of the cellular Internet of Things access network, the Radio Resource Control (RRC) layer can realize the functions of connection control, resource reservation, processing broadcast messages and paging messages, management of radio bearers, and security control. In addition, it is also responsible for the functions of the lower layer The configuration and management of parameters effectively apply relevant configurations to lower-layer protocols. At present, the implementation of wireless resource control in the cellular Internet of Things adopts the process defined by the protocol. In the actual deployment scenario, the specific method and parameters of wireless resource control are formulated by the operator,...
