Description

Energy saving method and system for MTC user equipment, user equipment, RNC

Technical field

The present invention relates to the field of wireless communications, and relates to an energy saving method and system for an MTC user equipment, a user equipment, and an RNC (Radio Network Controller).

Background technique

With the development of wireless Internet and smart terminals, the application of wireless data services has gradually expanded in various industries. MTC (Machine Type Communication) is one of the latest hot applications of the wireless Internet.

Energy Monitoring The MTC business is a sub-category of the MTC business. It is mainly used for billing meter reading of energy consumer goods such as electricity meters, gas meters, and water meters, as well as intelligent monitoring of power grid monitoring, industrial and other electronic equipment. The basic characteristics of this type of service are that the number of terminals is large, the service rate of bearers is small, and the power consumption has strict requirements. For wireless communication networks, the terminal has strict requirements on power consumption, which means that the terminal cannot remain in the wireless transmission and reception state for a long time.

The conventional method for solving the problem of terminal power consumption is to use DRX (Discontinuous Reception), the current UMTS (Universal Mobile Telecommunications System) wireless communication network, and the DRX reception period is up to 5120 ms. Therefore, the current UMTS wireless communication network working mode cannot meet the low power consumption requirements of the energy monitoring type MTC service. Currently, 3GPP proposes a solution to extend DRX. However, the extended connection state DRX policy has been rejected by 3GPP due to the limitation of the SFN (System Frame Number). Currently, the DRX is extended in idle state. Use deep sleep mode. However, without using the long DRX in the connection state, the UE cannot stay in the connection state for a long time in consideration of the power consumption problem; and the UE cannot monitor the network information in time if it enters the idle state and the DRX deep sleep mode from the connection state, only the real If there is no business demand for a long time, it can be transferred to the idle state long DRX deep sleep mode. Therefore, considering the energy saving requirements and network performance of the UE, the UE cannot directly transition from the connected state to the idle state long DRX deep sleep mode. Currently, there is no corresponding solution. In addition, for the idle state UE, the network side does not currently maintain the context information of the UE. Therefore, the network side cannot currently determine that the UE is in the idle state normal mode (in order to distinguish from the long DRX deep sleep mode, In this paper, the idle state in the usual sense is referred to as the idle state normal mode or the idle state long DRX deep sleep mode. Therefore, the network side does not know which paging mechanism is used to page the UE, and the network side cannot accurately perform the UE. Paging.
