Problems solved by technology

In this way, when the value of the IE "cellBarred" changes from "not barred" to "barred", that is, when the serving cell is blocked, it will bring uncertainty to the operation of the UE, which may cause UE and network signaling Abnormal interaction may also cause ongoing service interruption of UE

Embodiment 1

[0022] Embodiment 1 of the present invention provides a processing method when the serving cell is blocked in the connected state, such as figure 1 As shown, the method includes:

[0023] S101. A network device (which may be a base station in this implementation) sends a blocking message to a user equipment (UE). Specifically, the blocking message indicates that the serving cell controlled by the network device is in a blocking state;

[0024] S102. The user equipment ignores the received blocking message.

[0025] In practical applications, SIB1 (information block type 1) includes NAS (Network Attached Storage, Network Attached Storage) system information, timer and constant information used by UE in idle state and connected state, etc., which includes "cell Barred". The IE "cellBarred" in SIB1 (information block type 1) is used to indicate whether the cell allows the terminal to camp, that is: if "cellBarred" is "barred", it means that the UE cannot choose this cell to ca...

Embodiment 2

[0028] The processing method when the serving cell is blocked in the connected state provided by the embodiment of the present invention is described by assuming that the current serving cell needs to share services for adjacent cells and becomes the handover target cell as an example. When the current serving cell becomes the handover target cell, it can continue to provide normal services for the UE in the connected state, but the UE in the idle state is no longer allowed to choose this cell to camp on. In view of this, the method provided by the embodiment of the present invention ,Such as figure 2 As shown, the steps are:

[0029] S201. A network device (which may be a base station in this embodiment) sends a system information modification message to a user equipment (UE).

[0030] S202. After receiving the system information modification message, the user equipment updates its own system information.

[0031] S203. The network device sends a blocking message to the us...

Embodiment 3

[0036] The processing method when the serving cell is blocked in the connected state provided by the embodiment of the present invention is described by assuming that the communication line fails, for example, the line between the base station and the core network fails and needs to be repaired. Such as image 3 As shown, the method steps include:

[0037] S301. A network device (which may be a base station in this embodiment) sends a system information modification message to a user equipment (UE).

[0038] S302. After receiving the system information modification message, the user equipment updates its own system information.

[0039] S303. The network device sends a blocking message to the user equipment, where the blocking message indicates that the serving cell controlled by the network device is in a blocking state. In practical applications, "cellBarred" in SIB1 can be set to "barred", which means that the serving cell is in a blocked state.

[0040] S304. The user e...

Abstract

The embodiment of the invention provides a processing method and system for the blocking of serving cells under a connection state, relating to the field of communication. Operations are evidence-based after the serving cells are blocked, thereby avoiding the abnormal signaling interaction between user equipment (UE) and the network or the interruption of the ongoing service of the UE. The solution is as follows: network equipment transmits a blocking message to the user equipment, wherein the blocking message indicates that serving cells controlled by the network equipment are in the blocking state; and the user equipment neglects the received blocking message. The embodiment of the invention is used for processing blocked service cells under the connection state.

Description

technical field [0001] The present invention relates to the communication field, in particular to a processing method and system when a serving cell is blocked in a connected state. Background technique [0002] In the prior art, related criteria for cell selection and reselection by UE (User Equipment, user equipment) are given. The IE "cell Barred" in SIB1 (information block type 1) indicates whether the cell allows the UE to camp, and the cell Barred (restriction unit) here is a function specially suitable for the test mobile phone to make a test call. That is: if the IE is "barred", it means that the serving cell is blocked, and the UE cannot choose the cell to camp on; if the IE is "not barred", it means that the UE can choose the cell to camp on and initiate a related business. [0003] There are many reasons why the IE "cellBarred" is "barred". It may be that there is a communication problem in the cell and the normal service cannot be provided, for example, there i...
