Problems solved by technology

[0011] In view of the congestion of the core network entity in the related technology, the requests of all current MTC terminals will be rejected. If these MTC terminals initiate access again at the same time, it will inevitably cause the problem that the congestion state continues to be unresolved. No effective solution has been proposed so far.

Embodiment Construction

[0042] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0043] It is mentioned in related technologies that after the introduction of MTC applications, if a large number of MTC terminals access the system at the same time, the probability of core network signaling congestion will be greatly increased. Once the core network entity is congested, all current MTC terminal requests will be rejected. If these MTC The terminal then initiates access again at the same time, which will inevitably cause the congestion state to continue to be unresolved. In the current LTE system, there is a corresponding mechanism guarantee at the access layer, but the configurable UE re-access time is at most 16 seconds, which is not enough to alleviate the congestion in the case o...

Abstract

Disclosed are a method and system for a terminal to access a network. The method includes: determining an access delay time for a terminal to re-access the RAN side when the terminal receives an RRC connection reject message or a connection release message sent from the RAN side; and initiating by the terminal an access request toward the RAN side when the waiting time of the terminal is equal to or exceeds the access delay time. By way of the present invention, the following problem in the related art can be solved: the requests of all the current MTC terminals will be rejected when congestion occurs in the core network entity, and if these MTC terminals simultaneously initiate access again subsequently, this will inevitably cause congestion which cannot be resolved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for a terminal to access a network. Background technique [0002] H2H (Human to Human, 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 developmen...
