Problems solved by technology

In the next generation network, the UE also has the RRC idle state and the RRC connected state. When the UE transitions from the idle state to the connected state, it also generates more signaling overhead, and the transition time is too long, which cannot fully utilize the next generation network. The advantages

Embodiment 2

[0163] In the methods of Embodiment 2 and Embodiment 3, the core network and the UE determine whether the UE is suitable for entering the RRC connection inactive state based on the characteristics of the bearer, network slice and service flow of the UE. In other embodiments of the present invention, the core network and the UE may also determine whether the UE is suitable for entering RRC connection inactivity based on factors such as the UE's user subscription information and the type of the UE (for example, whether the UE is a terminal at a fixed location, etc.). When the core network or the UE determines that the UE is suitable for entering the RRC connection inactive state based on the UE's user subscription information, UE type and other factors, all bearers, network slices or service flows of the UE are suitable for entering the RRC connection inactive state. Similarly, when the core network or the UE determines that the UE is not suitable for entering the RRC connection ...

Embodiment 4

[0187] In the method of Embodiment 4, the method of actively paging by the access network device, triggering the UE to enter the RRC connection state, and the method of actively paging by the access network device based on the UE's access layer identifier can be called an access-based Layer paging mechanism, the method of paging by the core network is called the paging mechanism based on the non-access layer, the paging mechanism based on the non-access layer is an existing paging mechanism, and the paging mechanism based on the access layer is a new method of the present invention. Introduced paging mechanism. In one implementation method, two different paging mechanisms can be used simultaneously, that is, the UE can use different paging mechanisms according to the current RRC state. When the UE is in the RRC idle state, the UE uses the traditional non-access stratum-based paging mechanism. When the UE is in the RRC connection inactive state, the UE uses the access-stratum-b...

Embodiment 6

[0206] In Embodiment 6, the core network carries the paging information of the UE in the initial context setup request message. Of course, the core network may also carry the paging information of the UE in other messages. Or, the access network device sends a paging information request message to the core network, and the paging information request message is used to request to obtain the paging information of the UE, and the core network will return a paging information response message to the UE, and the paging information The response message includes the paging information of the UE.

[0207] In other embodiments of the present invention, the access network device may also acquire paging information from the UE. The access network device may request the UE to acquire the paging information of the UE, and may also receive the paging information of the UE actively sent by the UE. For example, before it is determined that the UE enters the RRC connection inactive state, the...

Abstract

The embodiment of the invention discloses a method and device for controlling a RRC (Radio Resource Control) state. An access network device obtains indication information of a RRC connection inactive state of UE; when the UE leaves a RRC connected state, the access network device determines that the UE enters the RRC connection inactive state or a RRC idle state based on the indication information of the RRC connection inactive state; and when that the UE enters the RRC connection inactive state is determined, the access network device stores contextual information of the UE and sends an instruction of entering the RRC connection inactive state to the UE to enable the UE to enter the RRC connection inactive state. In the abovementioned method, the access network device can control the UE to enter a suitable RRC state based on the condition of the UE, thereby reducing signaling overheads and improving system performance.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for controlling a Radio Resource Control (Radio Resource Control, RRC for short) state. Background technique [0002] In the Long Term Evolution (LTE for short) system, two RRC states are defined for user equipment (User Equipment, UE for short): RRC Idle (idle state) and RRCConnected (connected state). When the UE needs to perform services, the UE needs to establish an RRC connection with the network, that is, switch from an idle state to a connected state, and then transmit service data. [0003] During the transition of the UE from the idle state to the connected state, a lot of signaling overhead will be generated, and the transition time is too long, resulting in excessive data transmission delay. The next-generation network is an upgraded version of the LTE system, which can provide a higher transmission rate than the LTE system. T...
