Problems solved by technology

[0008] As mentioned above, when the Detach type is switch off, the UE can automatically release the UE context locally after waiting for a certain machine time. Therefore, there is no need for the base station to send the RRC Connection Release message, and the base station still sends the RRCConnection Release message in this case. The Release message will instead lead to an increase in signaling overhead, and may cause message retransmission, wasting precious wireless resources

example 1

[0068] Figure 9 It is a schematic flow chart of the shutdown Detach process when the UE is in EMM_REGISTERED state& ECM_IDLE state according to Example 1 of the present invention. This example will combine Figure 9 , which describes the detailed processing process of the resource release method provided by the embodiment of the present invention when the UE is in the EMM_REGISTERED state & ECM_IDLE state.

[0069] The UE is in the EMM_REGISTERED state & ECM_IDLE state, and the UE initiates a Detach process (including two types of Detach processes, switch off detach and normal detach). For Detach Type: switch off, after the UE sends the DetachRequest message, it releases the UE context locally, or releases the UE context after waiting for a certain machine time; for Detach Type: normal detach, after the UE sends the Detach Request message, it needs to wait for the Detach Accept message Then release the UE context. The UE first performs uplink synchronization through a rando...

[0073] Figure 10 It is a schematic flowchart of the shutdown Detach process when the UE is in the EMM_REGISTERED state & ECM_CONNECTED state according to Example 2 of the present invention. This instance will combine Figure 10 , describing the detailed processing process of the resource release method provided by the embodiment of the present invention when the UE is in the EMM_REGISTERED state & ECM_CONNECTED state.

[0074] The UE is in the EMM_REGISTERED state & ECM_IDLE state, and the UE initiates a Detach process (including two types of Detach processes: switch off detach and normal detach). For Detach Type: switch off, after the UE sends the DetachRequest message, it releases the UE context locally, or releases the UE context after waiting for a certain machine time; for Detach Type: normal detach, after the UE sends the Detach Request message, it needs to wait for the Detach Accept message Then release the UE context.

Abstract

The invention discloses a method and a system for releasing resources and a base station. The method comprises the following steps that: an evolved packet core (EPC) receives a detach request from user equipment (UE), wherein the detach request carries a detach type of the UE; the EPC informs a base station corresponding to the UE of the detach type; and in a case that the detach type is switch off, the base station cancels transmission of a radio resource control (RRC) connection releasing message to the UE. By the invention, empty signaling and resource expense are reduced, and the radio resources are saved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a resource release method, system and base station. Background technique [0002] In the third-generation mobile communication Long Term Evolution (LTE for short) system, the user needs to initiate a detachment process in some cases (for example, power off), so as to release the user equipment (User Equipment, UE for short). resources used. The following describes in detail the detachment process when the user turns off the phone. [0003] If the UE currently needs to be powered off, it initiates a shutdown detach (Detach) process, and the name of the message used is Detach Request (Detach Type: switch off). After the UE sends a shutdown Detach message and waits for a certain period of time, the UE does not need to wait for the Detach Accept message sent by the core network (Evolved Packet Core, EPC for short), and can directly release the UE context locally. [0004] After ...
