Embodiment Construction

[0043] As mentioned in the background technology, the network-side device (Network) allocates a measurement gap (Measurement GAP) to its served terminal (Terminal). In the measurement gap, the terminal does not need to send and receive uplink and downlink traffic channels, control channels or reference signals. However, only adjacent cell measurements are performed, specifically, measurements of inter-frequency adjacent cells and inter-system adjacent cells are performed. For example, in the LTE system, the configuration of the measurement interval format can be as described in Table 1. In Table 1, the terminal supports the measurement interval format, and a GAP time is defined as 6ms, and there are two corresponding periods of 40ms and 80ms.

[0046] In addition, in the LTE system, there are also measurement interval configurations in the following form. For details, refer to Table 2, which shows a closed subscriber group (Closed Subscriber Group,...

Abstract

The invention discloses a network side device, a terminal and a neighbor cell measurement method thereof. The method comprises the following steps: judging whether a DRX time interval distributed by current network side equipment is enough to perform current neighbor cell measurement or not; when the DRX time interval is not enough to perform current adjacent cell measurement, sending a message for representing a request for reconfiguration of discontinuous reception configuration parameters to the network side equipment, so that the network side equipment judges whether to reconfigure the discontinuous reception configuration parameters or not according to the current communication service quality requirement; and after a message representing that the network side device evaluates the request for reconfiguring the discontinuous reception configuration parameters is received, obtaining an extended DRX time interval when the updated discontinuous reception configuration parameter message is received. With the adoption of the scheme, the quality of the communication service and low power consumption can be maintained while the adjacent cell measurement duration of the 5G terminal isprolonged.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a network side device, a terminal and a method for measuring adjacent cells thereof. Background technique [0002] According to the requirements of Long Term Evolution (LTE) communication and New Radio (New Radio, NR) protocol, the network side device (Network) allocates a measurement interval (MeasurementGAP) to the terminal (Terminal) it serves, and in the measurement In the interval, the terminal does not need to send and receive uplink and downlink traffic channels, control channels or reference signals, but only performs neighbor cell measurement. However, under normal circumstances, it is not enough to perform neighbor cell measurement only by the measurement interval allocated by the network side equipment, and problems such as measurement delay and handover failure are prone to occur. And in view of certain time intervals in discontinuous reception...
