Description

Channel monitoring method, user equipment and network equipment

Technical field

The present invention relates to the field of communications, and in particular, to a channel monitoring method, a user equipment, and a network device.

Background technique

With the continuous development of science and technology, a new generation of mobile communication systems can provide users with more abundant communication services, and when users enjoy these communication services, the power consumption of user equipment is particularly serious. It is well known that power consumption is very important for user devices that use batteries. In order to reduce the power consumption of the user equipment as much as possible under the premise of guaranteeing the quality of service, the mobile communication system proposes a disconnected reception (English: Discontinuous Reception, DRX) mechanism. Under this mechanism, the user equipment is only fixed. The time is for receiving downlink data, and the rest of the time is in sleep mode with low power consumption. Specifically, as shown in FIG. 1, when in a data reception (DRX-on) phase of a discontinuous reception cycle (DRX cycle), the user equipment can receive downlink data when in a non-data reception (DRX-off) phase. At the same time, the user equipment enters the sleep mode and does not receive downlink data.

Generally, the network device and the user equipment use the calculation formula of the paging occasion: PO={(IMSI div K) mod DRX cycle length}+n×DRX cycle length+frame offset, and calculate the time when the user equipment can receive the downlink data, that is, Paging occasion (English: paging occasion, abbreviated as PO), so that the network device can send downlink data to the user equipment when the user equipment is in the DRX-on phase, ensuring that the user equipment successfully receives the downlink data; wherein, the international mobile subscriber identity The code (English: International Mobile Subscriber Identity, IMSI for short) is the IMSI of the user equipment, K is the number of paging channels, and n is an integer greater than 0.

In order to balance the power saving efficiency of the user equipment and the delay requirement for downlink data reception, the discontinuous reception period setting is relatively short, for example, in a Universal Mobile Telecommunication System (UMTS). The maximum time that the discontinuous reception period can be set is 5.12 seconds. However, as the terminal type and/or service type increase, the power saving efficiency becomes lower when a shorter discontinuous reception period is set. . The prior art adopts a method of increasing the time when the user equipment is in the DRX-off phase, that is, the time for extending the user equipment in the sleep mode to improve the power saving efficiency.

However, if the user equipment is in the DRX-off phase, that is, in the sleep mode for a long time, the above paging calculation formula cannot be used. For example, in UMTS, the system frame number (English: System Frame Number, SFN) is incremented every 10 milliseconds (ms), and the minimum SFN is 0, and the most SFN is 4095, that is, every At 40.96 seconds, the SFN will restart counting, that is, incrementing from 0 every 10ms until SFN is equal to 4095. Since the calculation formula of the paging timing described above is finally calculated to be a value less than 4096, if the time in which the UE is in the DRX-off phase is greater than 40.96 seconds, the network side cannot be calculated after calculating the PO by using the calculation formula of the paging timing described above. The network device and the user equipment cannot determine the time when the unified user equipment can receive the downlink data, that is, the PO, and the downlink data that is sent by the network device to the user equipment is lost.
