Embodiment Construction

[0025] 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. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] The conversion restriction relationship between RRC_LightConnection and RRC_IDLE and RRC_CONNECTED states of the present invention is as follows figure 1 As shown, RRC_LIGHTCONNECTED is not used in cross-MME and S-GW scenarios. figure 1 Among them, when the UE is in the RRC_IDEL state, if there is a service requirement, it will enter the RRC_CONNECTED state. When the UE is in the RRC_CONNECTED state, if the duration of neither uplink data transmission nor downlink data reception exceeds the specified duration one, the UE enters the RRC_LIGHTCONNECTED state. When the UE is in the RRC_LIGHTCONNECTED state, if there is uplink data transmission or downlink data reception, it will enter the...

Abstract

The present invention proposes a method for controlling UE state transition, including: when the UE is in the RRC_IDEL state, if there is a service requirement, then enter the RRC_CONNECTED state; When the specified duration is one, the UE enters the RRC_LIGHTCONNECTED state; when the UE is in the RRC_LIGHTCONNECTED state, if there is uplink data sent or downlink data received, it enters the RRC_CONNECTED state; if neither uplink data is sent nor downlink data is received for longer than the specified duration two, Then enter the RRC_IDLE state.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method for controlling UE state transition. Background technique [0002] With the development of wireless mobile communication technology, people put forward higher and higher requirements for high speed, low delay and low cost. The LTE (Long Term Evolution) project was born under such a background, pursuing higher peak rates and shorter transmission delays. [0003] The main performance goals of the LTE project include: providing a peak rate of 100 Mbps downlink and 50 Mbps uplink in a 20MHz spectrum bandwidth, improving the performance of cell edge users and increasing cell capacity; reducing system delay, and the one-way transmission delay within the user plane is less than 5ms. The transition time of the control plane from the sleep state to the active state is less than 50ms, and the transition time from the resident state to the active state is less than 100ms; it sup...
