Embodiment 1

[0045] In the LTE system, different types of terminals, including H2H devices and MTC devices, access the network, some are in the connected state, and some are in the idle state.

[0046] At a certain moment, due to the increase in the load of the core network, the core network sends an overload control instruction to the base station. After the base station obtains the overload control instruction, it selects some terminals according to the type of terminal, the priority of the service initiated by the terminal, or the priority of the terminal. Release is implemented, for example, an MTC device may be selected for release, or a terminal with a low priority is selected for release, or a terminal with a low service priority is selected for release, so as to reduce the load on the network side.

[0047] In this embodiment, the base station selects a low-priority MTC device to release its RRC connection, and the release process is as follows image 3 Shown:

Embodiment 2

[0055] In the LTE system, different types of terminals, including H2H devices and MTC devices, access the network, some are in the connected state, and some are in the idle state.

[0056] At a certain moment, the base station detects that its own load is very high, or detects that the core network load is high through a background operation and maintenance (OAM) server, and the base station makes a decision to release some terminals. In this embodiment, the base station selects a low-priority terminal to release according to the service priority. The base station sends RRC connection release signaling to the terminal, and the signaling includes a release reason. After receiving the release signaling, the terminal sets the waiting time according to the access delay time in the system message. It should be noted that the terminal can read the access delay time in the system message after receiving the release signaling, or obtain the access delay time in the system message bef...

Embodiment 3

[0064] In the LTE system, different types of terminals, including H2H devices and MTC devices, access the network, some are in the connected state, and some are in the idle state.

[0065] At a certain moment, the base station detects that its own load is very high, or the core network load is detected by the background operation and maintenance server, and the base station makes a decision to release some terminals. In this embodiment, the base station selects a low-priority terminal to release according to the service priority. The base station sends RRC connection release signaling to the terminal, and the signaling includes a release reason. After receiving the release signaling, the terminal obtains the access delay time according to the protocol predefined method. The protocol predefined method may include one of the following scenarios or a combination of them:

[0066] According to the type of terminal, the access delay time is pre-agreed, for example, the access dela...

Abstract

The present invention provides a method for a terminal to access a network and the terminal. The method includes: when the terminal receives the radio resource control RRC connection release signaling sent by the network side, the terminal determines the waiting time required for re-accessing the network side; When the terminal determines that the waiting time is equal to or exceeds the waiting time, the terminal re-initiates an RRC connection request to the network side. Adoption of the present invention can solve the above-mentioned problem that many MTC devices initiate RRC connection requests at the same time after they are released, which will still cause a lot of impact on the network, and even cause network overload.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for a terminal to access a network and a terminal. Background technique [0002] H2H (Human to Human) communication refers to the communication between people. People communicate through the operation of equipment. The existing wireless communication technology is developed based on H2H communication. The narrow definition of M2M (Machine to Machine) is machine-to-machine communication, and the broad definition is networked applications and services centered on the intelligent interaction of machine terminals. M2M is an informatization solution based on intelligent machine terminals and using multiple communication methods as access means to provide customers with informatization solutions to meet customers' informatization needs in monitoring, command and dispatch, data collection and measurement. [0003] The development of wireless technology is an impo...
