no. 1 Embodiment

[0262] In the first specific embodiment, the wireless communication network system includes base stations whose RRC states only include RRC connection state and RRC idle state, and the RRC states of the first base station and the second base station both include RRC connection RRC state and RRC idle state, the RRC state only includes RRC connected state and RRC idle state. The second acquisition information.

[0263] In the first specific embodiment, the base station in the wireless communication network system includes but is not limited to the base station whose RRC state only includes the RRC connected state and the RRC idle state, and it may also include the RRC state including the RRC connected state, the RRC idle state and the RRC light state. A base station in a connected state, and a base station in an RRC state including an RRC connected state, an RRC idle state, and an RRC inactive state. In order to facilitate the understanding of the technical solution of the embo...

no. 2 Embodiment

[0273] The difference from the first specific embodiment is that in the second specific embodiment, the base station whose RRC state only includes RRC connected state and RRC idle state transmits to the user terminal in the covered cell through RRC dedicated signaling The first acquisition information for acquiring network location information and the second acquisition information for acquiring a wake-up signal.

[0274] The RRC state of the same core network location area in the wireless communication network system only includes the base station in the RRC connected state and the RRC idle state based on the same transmission method and time-frequency resource to deliver the core network location to the user terminal in the covered cell An area identifier and a wake-up signal for indicating that the user terminal has a paging message; the core network location area identifier may specifically include a mobile country code MCC, a mobile network number MNC, and a tracking area ...

no. 3 Embodiment

[0283] In the third specific embodiment, the wireless communication network system includes a base station whose RRC state includes RRC light connection state or RRC inactive state, and the RRC states of the first base station and the second base station include RRC light connection state or RRC inactive state, the RRC state includes RRC connected state and RRC idle state base station to which the access network location area belongs to is represented by the cell identification list; RRC state includes RRC lightly connected state or RRC inactive state base station, through broadcast message The first acquisition information for acquiring network location information and the second acquisition information for acquiring a wake-up signal are sent to the user terminal in the covered cell.

[0284] In the third specific embodiment, the base stations in the wireless communication network system include but are not limited to base stations whose RRC states include RRC connected state,...

Abstract

Disclosed are a power-saving method for a user terminal and a device, for resolving a problem in the prior art in which changing a resident cell of a user terminal leads to relatively large power consumption. The method comprises: in the process of changing the resident cell of a user terminal from a first cell to a second cell, the user terminal, when in the first cell, receiving first acquisition information from a first base station corresponding to a first cell for acquiring network location information, and when in the second cell, receiving network location information issued by a second base station corresponding to a second cell; the user terminal determining whether a network location identifier for the second cell in the network location information issued by the second base station is included in a list of network location identifiers of the user terminal; and if so, the user terminal receiving, based on second acquisition information received while in the first cell from the first base station for acquiring a wake-up signal, a wake-up signal issued by the second base station, so as to return to an operating state based on the wake-up signal and to receive a paging message.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of wireless communication, and in particular to a method and device for saving power of a user terminal. Background technique [0002] With the development of wireless network communication technologies, the types of user terminals in the wireless communication network system and the types of services carried by the user terminals are becoming more and more diverse. In the case of ensuring service availability of user terminals in a wireless communication network system, the prior art reduces unnecessary occupation of wireless network resources and power consumption of user terminals through a user terminal wake-up mechanism. [0003] The user terminal wake-up mechanism means that the user terminal in the working state does not perform data transmission and reception within a predetermined time, and the user terminal enters a sleep state with extremely low power consumption. Wake-u...
