Problems solved by technology

[0011] 1. When the network configures the Wait Time value, it is generally set according to the current system load status, because the random access process has not been completed at this time, and the network cannot know what type of terminal is requesting RRC connection, and its business priority level how
Therefore, it is impossible to determine which part of the MTC terminal's request to reject;
[0012] 2. If the configured waiting time is not long enough, the congestion situation may still continue. However, the currently configured waiting time is only 16 seconds at most. Therefore, it cannot satisfy the congestion caused by thousands of MTC terminals simultaneously initiating access requests

Embodiment 1

[0063] In this embodiment, an MTC terminal is taken as an example to specifically introduce the technical solution of the present invention.

[0064] In this embodiment, for the MTC terminal, the network can configure different waiting time control information according to the following factors, such as the waiting time adjustment factor, which specifically refers to the wait time scaling factor (waiting time level factor) in this embodiment:

[0065] The priority of an MTC terminal mainly refers to the capability of the terminal. The priority of the terminal is determined by the operator and is not exactly the same as the capability of the terminal;

[0066] Different types of priorities for MTC applications, for example, fire alarms are MTC applications with high priority, and electronic meter reading is an MTC application with low priority;

[0067] The MTC terminal access class can be based on the ACB (Access Class Barring, access class barring) mechanism. Each terminal ha...

Embodiment 2

[0076] This embodiment still takes the MTC terminal as an example to introduce the technical solution of the present invention in detail.

[0077] In addition to the manner mentioned in the first embodiment above, the MTC terminal can also determine the length of time to wait in the following manner:

[0078] 1. Use the configured waiting time adjustment amount

[0079] Increase the wait time adjustment (wait time offset) on the basis of the value of the wait time configured in the existing RRC Connection Release message; if the wait time is configured as 12 and the wait time offset is set to 5, then the terminal can set a local The timer T302=12+5=17s, and the access request is allowed again after T302 times out.

[0080] 2. Extend the high-order bits on the basis of the existing wait time

[0081] The wait time value configured in the existing RRC Connection Release message is 4 bits, and then extended by 2 bits (wait time factor), the value of the extended bit is equivale...

Embodiment 3

[0087] Considering that when the terminal accesses, it may not receive the access rejection message from the network side due to abnormal reasons, and at this time, the terminal will not be able to determine the time to re-connect to the network. In view of this situation, in order to avoid the impact on the network caused by a large number of terminals simultaneously initiating re-access after an abnormality occurs on the network side, this embodiment provides a terminal access time control method, which specifically includes:

[0088] Pre-configure different waiting time values ​​for terminals in the network;

[0089] After the terminal sends an access request message to the network side, if it does not receive an access rejection message from the network side within a specified time, it determines the waiting time for re-connecting to the network according to the pre-configured waiting time value.

[0090] Among them, when configuring different waiting time values ​​for ter...

Abstract

The invention discloses a method and system for controlling access time of a terminal. The method comprises the following steps of: configuring different access time control information for the terminal in a network; and determining time needing to wait for re-accessing the network according to the access time control information after the terminal receives an access refuse message of a network side. Through the method and system for controlling the access time of the terminal, disclosed by the invention, the waiting time for accessing the terminal can be reasonably configured, and the impact on the network when a lot of terminals access the network at the same time is avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a terminal access time control method and system. 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. It is based on intelligent machine terminals and uses 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 important factor in the de...
