Problems solved by technology

This solid monitoring mechanism based on the DRX / DTX cycle is not conducive to UE power saving
[0011] (2) There is no specific solution to solve the UE running multiple services at the same time
[0012] Because when the user runs multiple services, the network side sends an RRC establishment message to the UE after receiving the UE's RRC connection request message. The RRC establishment message contains multiple DRX / DTX cycle factors corresponding to the service type. Indicates that all DRX / DTX cycle factors are stored, but there is no corresponding technical solution to solve how the UE processes multiple services at the same time according to the stored DRX / DTX cycle factors, and how to dynamically adjust the DRX / DTX cycles of the UE and the network side

Embodiment 1

[0028] Such as image 3 As shown, when the user runs only one service, the network side uses the DRX / DTX cycle corresponding to the service as the DRX / DTX cycle, and uses the DRX / DTX cycle as the predetermined time of the detection buffer (Buffer). The network side indicates the DRX / DTX cycle factor corresponding to the service to the UE. The UE stores the DRX / DTX cycle factor, uses the DRX / DTX cycle corresponding to the DRX / DTX cycle factor as the DRX / DTX cycle of the UE, and receives the data flow delivered by the network side.

[0029] When running the web browsing service on the UE, the user clicks on the news link to start the first session of the web browsing service. If there is no data stream sent from the network side to the UE, it means that the first session is over. During the time period before the UE initiates another web page browsing service, the network side detects whether there is any data flow sent to the UE in the buffer according to the predetermined tim...

Embodiment 2

[0034] Still taking the UE running the web browsing service as an example, the network side takes any value between the DRX / DTX cycle and the LTE_idle cycle corresponding to the web browsing service as the predetermined time for detecting the buffer.

[0035] After the user establishes a connection with the network side, the network side indicates the DRX / DTX cycle factor corresponding to the web page browsing service to the UE, and the UE receives the data flow sent by the network side according to the DRX / DTX cycle factor corresponding to the DRX / DTX cycle factor.

[0036] The network side sends the data stream according to the DRX / DTX cycle corresponding to the web browsing service, and the UE receives the data stream according to the DRX / DTX cycle. The network side detects whether there is data to be sent to the UE in the buffer according to the predetermined time. If so, the network side continues to send data to the UE according to the DRX / DTX cycle, and the UE receives ...

Embodiment 3

[0040] Taking the VoIP service and web browsing service initiated by the user at the same time as an example, after comparing the DRX / DTX cycle factors of the two services, the UE selects the k value corresponding to the VoIP service as the DRX / DTX cycle factor of the UE, then the DRX / DTX cycle factor of the UE The cycle is equal to the DRX cycle of the VoIP service. The UE receives the data streams of the two services delivered by the network side in the DRX / DTX cycle, and the network side still sends the data streams respectively according to the DRX / DTX cycles corresponding to the two services.

[0041] Such as Figure 5 As shown, when the network side selects any value between the DRX / DTX cycle of the VoIP service and the LTE_idle cycle as the predetermined time. The network side detects whether there is a new data flow delivered to the UE in the buffer according to the predetermined time, and if there is, the UE continues to receive the new data flow. If not, the networ...

Abstract

The method for variable discrete receiving / transmitting period comprises: UE receives NS data flow according to discrete receiving / transmitting period from NS; a NS detects whether there is data to UE in its buffer; if not, NS adjusts the discrete receiving / transmitting period. This invention dynamic adjusts the discrete receiving / transmitting period according to periodical detecting data flow toward UE, even on state of running multiple businesses.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to LTE technology, specifically a method, network and user terminal for realizing a variable discontinuous reception / discontinuous transmission (DRX / TX) cycle. Background technique [0002] The third-generation mobile communication system WCDMA 25304v3.7.0 protocol stipulates that in order to reduce the power consumption of the user terminal (UE) in the idle mode, the UE adopts discontinuous reception (DRX: Discontinuous Reception) in the idle mode, and only needs to be in each DRX cycle A PI (Paging Indication) is monitored in a paging time within a period, and when there is a paging message sent to the UE on the network side, the paging indication message is also discontinuously transmitted (DTX: Discontinuous Transmitting) to the UE accordingly. The DRX / DTX cycle (DRX Cycle Length) of the UE corresponds to the DRX / DTX cycle (DTX Cycle Length) measured by the network. ...
