Problems solved by technology

[0010] To sum up, in the prior art, R13NB-IoT UE does not support the mobility of the connected state, but NB-IOT needs to enhance the mobility of the connected state in some scenarios (such as logistics tracking), but it has not been given yet. How to determine whether the UE needs to support mobility in the connected state?

Embodiment 1

[0170] Embodiment one: if Figure 4 As shown, the process of judging that the UE needs to support mobility in the connected state specifically includes the following steps:

[0171] S401. The UE determines whether it needs to support mobility in a connected state.

[0172] The specific way of judging depends on the implementation of the UE. For example:

[0173] The UE determines that it is currently in a static state, and then determines that the UE does not need to support mobility in the connected state;

[0174] Or, the UE determines that the UE does not need to support mobility in the connected state according to the mobility history information when it was in the idle state before, such as the dwell time and dwell duration of the previous cell;

[0175] Or, the UE determines that the UE needs to support the mobility of the connected state according to the historical information when it was in the connected state and combined with the capabilities of the UE. Therefore...

Embodiment 2

[0180] Embodiment two: if Figure 5 As shown, the process of judging that the UE needs to support mobility in the connected state specifically includes the following steps:

[0181] S501. The UE sends an RRC connection establishment complete, RRC connection reestablishment complete, or RRC connection recovery complete message to the base station.

[0182] Wherein, if the UE determines that the UE supports connected state mobility according to its own capability information, the current mobility state of the UE is carried in the RRC connection establishment complete, RRC connection reestablishment complete, or RRC connection recovery complete message sent to the base station; otherwise, the UE is not carried The current mobile state of .

[0183] S502. The base station judges, according to the message sent by the UE in step S501, whether to configure related behaviors supporting mobility in the connected state for the UE. specifically:

[0184] If the message sent by the UE ...

Embodiment 3

[0186] Embodiment 3: Similar to Embodiment 2, the process of judging that the UE needs to support mobility in the connected state specifically includes the following steps:

[0187] Step 1: The UE sends an RRC connection establishment complete, RRC connection reestablishment complete or RRC connection recovery complete message to the base station.

[0188] Wherein, if the UE determines that the UE supports connected state mobility according to its own capability information, it further judges the current mobility state of the UE, and if the UE is currently in a static state, it sends an RRC connection establishment complete, RRC connection reestablishment complete, or RRC connection recovery complete The message carries the information that the UE is in a static state; if the UE is currently in a normal or medium-speed mobile state, the UE’s current mobile state will be carried in the RRC connection establishment complete, RRC connection reestablishment complete, or RRC connect...

Abstract

The embodiments of the invention provide a method and a device for judging UE needing to support connection state mobility and sending information; the method and the device are used for judging whether the UE needs to support the mobility of the connection state. The method for judging the UE needing to support the mobility of the connection state provided by the embodiments of the invention comprises the following steps: determining auxiliary information used for judging whether the UE needs to support the mobility of the connection state or not; and judging whether the UE needs to support the mobility of the connection state or not according to the auxiliary information.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for judging whether a UE needs to support mobility in a connected state, and for sending information. Background technique [0002] Narrow Band Internet of Things (NB-IoT) working phase (Work Item, WI) passed and started in the 3rd Generation Partnership Project (3GPP) Release 13 (Release 13, R13) phase . [0003] The goal of the narrowband Internet WI phase is to standardize the wireless access of the Cellular Internet of Things (CIoT). The technology is extended based on Long Term Evolution (LTE) / Long Term Evolution-Advanced (LTE-A). The main network characteristics or goals considered are: enhanced indoor coverage, support for a large number of low-speed device access, low Delay sensitivity, reduce equipment cost, reduce equipment power consumption, optimize network architecture, etc. [0004] In order to be suitable for informatio...
