specific Embodiment 1

[0082] Specific embodiment 1: Handover process failure handling.

[0083] Figure 4 It is a flow chart according to the handover process failure handling in the specific embodiment of the present invention:

[0084] Step 1: The UE receives the handover command and requires to maintain the connection in the source cell (such as Figure 4 "Receptionof HO CMD").

[0085] Step 2: The UE maintains the connection with the source cell (such as Figure 4 in "Start t304; keep t310running").

[0086] Step 3: If the UE fails to connect, the UE distinguishes the type of failure and handles it, and judges whether to maintain the connection with the source cell (such as Figure 4 "Is the source connection released" in):

[0087] If the source cell connection is not released, but the handover to the target cell fails (such as Figure 4 "HOFailure"), the UE performs Type 1 behavior (such as Figure 4 in Action 1);

[0088] If the connection of the source cell is not released, but the ...

specific Embodiment 2

[0132] Specific embodiment 2: Handling of the failure of the process of changing the secondary cell group.

[0133] Figure 5 It is a flow chart of the failure handling process of changing the secondary cell group according to a specific embodiment of the present invention:

[0134] Step 1: UE receives the secondary cell group change command, and requires to maintain the connection in the source secondary cell group (such as Figure 5 "Reception of SCG change CMD").

[0135] Step 2: The UE maintains the connection with the source secondary cell group (such as Figure 5 "Start t307; keept313running" in ).

[0136] Step 3: If the UE fails to connect, the UE distinguishes the type of failure and handles it, and judges whether to maintain the connection with the source secondary cell group (such as Figure 5 "Is the source SCG connection released" in ):

[0137] If the source secondary cell group connection is not released, but the change to the target secondary cell group fa...

Abstract

The invention provides a cell connection failure processing method and device. The method comprises the steps of receiving a change command for indicating change of a cell group; determining that connection with a source cell group and / or a target cell group is unsuccessful when the cell group is changed according to the change command; and determining a connection failure type and processing theconnection failure in a processing mode corresponding to the failure type. Through application of the method and the device, the problem that in related technologies, the wireless connection failure and data break occur in a wireless connection process is solved, and the effect that the connection is recovered and the data is transmitted relatively fast when the wireless link problem occurs in a user device is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for processing cell connection failure. Background technique [0002] Because the current Long Term Evolution (LTE for short) system adopts a switching method in which the connection is disconnected in the source cell first and then the connection is established in the target cell (ie, break-before-make, break-before-make). The sending and receiving of business data will be interrupted. Therefore, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) discussion group provides a new solution for simultaneously maintaining the connection of the user equipment (User Equipment, referred to as UE) in the source cell and the target cell (that is, make-before -break, build first and then break). It is used to reduce the handover interruption delay at the UE side. [0003] Such as figure 1 Shown is the flow chart of swi...
