In order to better understand the method for configuring a measurement gap disclosed in the embodiments of the present disclosure, a communication system to which the embodiments of the present disclosure are applicable is firstly described below.
Referring to

The RAN device 101 in the embodiments of the present disclosure is an entity used to send or receive a signal on a network side. For example, the RAN device 101 may be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in a future mobile communication system or an access node in a wireless fidelity (WiFi) system, and the like.

The network device provided in the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be referred to as a control unit. A structure of CU-DU allows a protocol layer of the network device, such as a base station, to be split, some functions of the protocol layer are placed in the CU for centralized control, and some or all of the remaining functions of the protocol layer are distributed in the DU, which is intensively controlled by the CU.
The CN device 102 in the embodiments of the present disclosure is an entity for location estimation on a network side. For example, the CN device 102 may be a location management function (LMF), or the like.
The terminal device 103 in the embodiments of the present disclosure is an entity used to receive or send the signal on a user side, for example, a mobile phone. The terminal device may also be referred to as a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), or the like. The terminal device may be an automobile with a communication function, an intelligent automobile, a mobile phone, a wearable device, a pad, a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in the self-driving, a wireless terminal device in the remote medical surgery, a wireless terminal device in the smart grid, a wireless terminal device in the transportation safety, a wireless terminal device in the smart city, a wireless terminal device in the smart home, and the like. The specific technology technologies and specific device forms used by the terminal device are not limited in the embodiments of the present disclosure.
In the 5G NR system, more than one positioning technology is introduced, and some positioning technologies require a terminal to measure a positioning reference signal (PRS), so that the terminal needs to request a measurement gap (MG) for measuring the PRS from a network.
In the related art, when the terminal device 103 needs to perform a positioning measurement requested by the core network device 102, if no measurement gap is configured for the terminal device 103 at present or the configured measurement gap cannot meet requirements of the terminal device 103, the terminal device 103 requests the measurement gap from the RAN device 101 through a radio resource control (RRC) message.
As shown in
The process of requesting and obtaining the measurement gap by the terminal device 103 is implemented through RRC messages, which requires a long time, and has a relatively high positioning delay, so that a media access control (MAC) control element (CE) of a MAC layer is considered to be used to request the RAN device 101 to activate/deactivate the measurement gap to reduce the positioning delay. The terminal device 103 may request the RAN device 101 to activate/deactivate the measurement gap through the MAC CE. The RAN device 101 may also activate/deactivate the measurement gap for the terminal device 103 through the MAC CE. However, compared with the RRC message, the MAC CE contains less information.

The terminal device receives the measurement gap configuration information sent by the RAN device, and may request the access network device to activate or deactivate the measurement gap for the terminal device according to the measurement gap configuration information.
In the embodiment of present disclosure, the measurement gap configuration information determined by the RAN device is first measurement gap configuration information, the measurement gap configuration information determined by the core network device is second measurement gap configuration information. That is, both the RAN device and the core network device can configure the measurement gap for the terminal device.
It may be understood that since the core network device cannot directly perform communication interaction with the terminal device, the second measurement gap configuration information determined by the core network device needs to be sent to the terminal device through the RAN device.

That is, if the access network device and the core network device both configure the measurement gap for the terminal device and the measurement gap configuration information configured by the access network device is different from the measurement gap configuration information configured by the core network device, the terminal device configures the measurement gap according to the first measurement gap configuration information determined by the RAN device.
In some embodiments, the measurement gap configuration information is the first measurement gap configuration information determined by the RAN device, and receiving the first measurement gap configuration information sent by the RAN device includes:
receiving an RRC message sent by the RAN device, in which the RRC message includes the first measurement gap configuration information.

The first measurement gap configuration information is used to request a target measurement gap for the terminal device from at least one measurement gap configured by the first measurement gap configuration information. The first measurement gap configuration information includes a period, an offset parameter, and the like of the at least one measurement gap.
That is, before the terminal device needs to use the measurement gap, the first measurement gap configuration information is obtained to configure at least one measurement gap for the terminal device. When the terminal device needs to use the measurement gap, the target measurement gap used by the terminal device is requested from at least one pre-configured measurement gap.
In some embodiments, the terminal device may request the target measurement gap, and the core network device may also request the target measurement gap.
The terminal device receives the first measurement gap configuration information through the RRC message sent by the RAN device.
Optionally, the RRC message may be an RRC reconfiguration message.

As shown in
At step 1201, an LPP message sent by an RAN device is received, the LPP message includes second measurement gap configuration information.
The second measurement gap configuration information is determined by a core network device and used to pre-configure a measurement gap for the terminal device. The second measurement gap configuration information is used to configure at least one measurement gap.
The second measurement gap configuration information is used to request a target measurement gap for the terminal device from at least one measurement gap configured by the second measurement gap configuration information. The second measurement gap configuration information includes a period, an offset parameter, and the like of the at least one measurement gap.
That is, before the terminal device needs to use the measurement gap, the second measurement gap configuration information is obtained to configure at least one measurement gap for the terminal device. When the terminal device needs to use the measurement gap, the target measurement gap used by the terminal device is requested from at least one pre-configured measurement gap.
In some embodiments, the terminal device may request the target measurement gap, and the core network device may also request the target measurement gap.
It may be understood that since the core network device cannot directly perform communication interaction with the terminal device, the second measurement gap configuration information determined by the core network device needs to be sent to the terminal device through the RAN device.
The terminal device receives the second measurement gap configuration information sent by the core network device through the LPP message sent by the RAN device.
Optionally, the LPP message may be at least one of LPP provide assistance data or LPP Request location information.
