Embodiment 1

[0080] In this embodiment, when the radio access network RAN ​​is congested, the SGSN / MME learns that the RAN is congested, and after receiving the Urgent trigger request from the MTC terminal, uses high-priority paging to page the MTC terminal. After receiving the high-priority paging message, the MTC terminal uses the high-priority indication to replace its configured low-priority or normal-priority attributes, and carries the high-priority indication in the RRC establishment request and service request. After receiving the high priority indication in the RRC request, the radio access network allocates radio resources for the terminal, establishes a radio bearer, and sends a service request message to the SGSN / MME. The SGSN / MME requests the RAN to allocate wireless user plane bearer resources for the terminal and establish the user plane bearer, and the MTC terminal and the MTC Server establish data communication through the user plane bearer.

Embodiment 2

[0094] In this embodiment, after receiving the Urgent trigger request for the MTC terminal, the SGSN / MME still uses high-normal paging to page the MTC terminal. After receiving the normal paging message, the MTC terminal carries the configured low priority indicator or normal priority indicator in the RRC request and service request messages according to the existing technology to access, but the RAN will reject the RRC request after receiving it. The RAN notifies the MTC terminal of the cause of RAN congestion in the rejection message. After the MTC terminal learns of the RAN congestion, it replaces the low priority or normal priority attributes configured by itself with a high priority indicator, and carries it in the RRC establishment request and service request. High priority indication. After receiving the high priority indication in the RRC request, the radio access network allocates radio resources for the terminal, establishes a radio bearer, and sends a service reques...

Embodiment 3

[0110] In this embodiment, after receiving the Urgent trigger request for the MTC terminal, the SGSN / MME still uses high-normal paging to page the MTC terminal. After the MTC terminal receives the general paging message, if the MTC terminal is still allowing the extension of the waiting time timer, the MTC terminal may determine that the RAN is in a congested state at this time. After the MTC terminal knows that the RAN is congested, it uses the high priority indication to replace the low priority or normal priority attributes configured by itself, and carries the high priority indication in the RRC establishment request and service request. After receiving the high priority indication in the RRC request, the radio access network allocates radio resources for the terminal, establishes a radio bearer, and sends a service request message to the SGSN / MME. The SGSN / MME requests the RAN to allocate wireless user plane bearer resources for the terminal and establish the user plane b...

Abstract

The invention discloses an access method, an access device and an access system for a machine type communication terminal. The access method comprises the following steps: a MTC (machine type communication) terminal is used for receiving a notice from a mobile management network element of the communication network, wherein the notice indicates that high priority activation is performed on the MTC terminal by a MTC server; the MTC terminal determines current RAN (radio access network) congestion; and the MTC terminal sends a request message about access to the network with the high priority indication to the network side. According to the invention, the MTC terminal can set up user plane load in the mobile communication network under the situation of RAN congestion, so as to establish data communication with the MTC server.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an access method, device and system for a machine type communication terminal. Background technique [0002] Machine-to-machine (M2M) business is a networked application and service centered on the intelligent interaction of machine terminals. It uses intelligent machine terminals, transmits information through wireless networks, and provides customers with informatization solutions to meet customers' informatization needs for monitoring, command and dispatch, data collection and measurement. [0003] Since machine type communication (MTC) devices (also called MTC terminals) are unattended, it is necessary to optimize the 3GPP network so that the network has the ability to activate the terminals, so that when the MTC Server needs the MTC terminals to report data or By controlling it, the MTC device can be triggered at any time to establish data communication with the MTC Serve...
