[0005] Since the serial number received by the newly created radio link control entity is not 0, the drifting radio link controller will judge that the serial number carried in the message is illegal at this time, triggering the radio link control reset process, and the maximum radio link configured on the network side The number of link control resets is 1, which will cause an unrecoverable error, resulting in the loss of data information that actually needs to be transmitted, resulting in call drop

Embodiment Construction
[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0050] The current process of user equipment (User Equipment, referred to as UE) migration refers to that in a Universal Mobile Telecommunications System (abbreviated as UMTS) network, each radio network controller (referred to as RNC) is responsible for controlling its Control several cells under the area, and control the user equipment UE residing in the cell, and allocate radio link resources for UE. This kind of radio network controller is called serving ra...

The embodiment of the invention discloses a method and a device for preventing radio link control (RLC) reset and relates to the field of communication. By means of the mode of preventing the RLC reset, the problem of call drop caused by the fact that serial numbers are inconsistent in transferring scene is solved. The method includes that when a user device is transferred to a drifting wireless network controller, a wireless bearing between the drifting wireless network controller and the user device is newly established, land mobile access network mobile messages are sent to the user device, simultaneously the times of discarding a data protocol data unit in uplink data sent by the user device is set to be 0, the uplink data sent by the user device is received by the drifting wireless network controller, whether an uplink data sequence number is 0 or not is determined, and whether the discarding times of the data protocol data unit exceed the set maximum discarding times or not and whether a sequence number of the data protocol data unit is 0 or not are determined. The embodiment of the invention is applied to the field of the communication.
Description
technical field [0001] The invention relates to the communication field, in particular to a method and equipment for avoiding reset of radio link control RLC. Background technique [0002] In the Universal Mobile Telecommunications System (UMTS) network, each radio link controller (Radio Network Controller, RNC) is responsible for controlling several cells in the UMTS network and controlling the resident User Equipment (UE for short), and allocate radio link resources for the user equipment, when the user equipment moves from a cell controlled by a radio link controller to a cell controlled by another radio link controller, the user equipment The serving radio link controller will change, and this change process is called user equipment migration. [0003] During data transmission during the mutual migration process between radio link controllers, when migrating to a drifting radio link controller, an abnormal migration situation occurs. The network side sends a land mobile...
