Problems solved by technology

[0007] It can be seen that after receiving the resource switching instruction from the eNB, the UE changes the resources used. When the eNB performs the switching, because the UE does not perform the switching synchronously, it will cause data packet loss or even service interruption, which will seriously affect the call. quality
[0008] Therefore, the current method for implementing resource switching cannot reliably perform resource switching, and the communication quality is low

Embodiment 1

[0031] This embodiment takes implementing frequency resource switching in an LTE system as an example to specifically describe a method for implementing resource switching. figure 1 It is a flowchart of a method for implementing resource switching in the first embodiment of the present invention. see figure 1 In this embodiment, the resource switching instruction of the frequency resource carries the resource allocation signaling for the acknowledgment information of the resource switching instruction to allocate resources, and a timer is used to quickly find errors in the frequency resource switching process. Specifically include the following steps:

[0032] Step 101: the eNB sends a resource switching instruction for frequency resources to the UE, and starts a timer T1 at the same time.

[0033] In this embodiment, when the eNB finds that a better frequency resource can be scheduled for the UE, the eNB sends a resource switching instruction for the frequency resource to t...

Embodiment 2

[0056] Figure 4 It is a schematic structural diagram of a system for implementing resource switching in the second embodiment of the present invention, the system includes a base station 410 and a user terminal 420;

[0057] The base station 410 determines the time for performing the handover, and sends a resource switching instruction to the user terminal 420, where the resource switching instruction carries time information corresponding to the time for performing the handover, and performs resource switching at the determined time for performing the handover;

[0058] The user terminal 420 acquires time information according to the received resource switching instruction, and performs resource switching with the base station 410 at a time corresponding to the time information for performing switching.

[0059] The user terminal 420 may also send confirmation information of the resource switching instruction to the base station 410 after receiving the resource switching ins...

Abstract

The embodiment of the invention discloses a method for realizing a resources switch, which comprises the following steps: a base station determines the time for executing the switch and sends a resource switching order which carries time information corresponding to the switching time to a user end; the time information is acquired by the user end according to the resource switching order; the resource switch is executed by the base station and the user end in the switch execution time. The embodiment of the invention also discloses a system for realizing the resource switch, which comprises the base station and the user end. In addition, the embodiment of the invention discloses the base station and the user end for realizing the resource switch. The base station comprises a time determination module, an order sending module and a switch execution module. The user end comprises an information acquisition module and the switch execution module. By applying the invention, the reliability of the resource switch is enhanced so that the communication quality is improved.

Description

technical field [0001] The present invention relates to communication system scheduling technology, in particular to a method, system, base station and user terminal for realizing resource switching. Background technique [0002] In a mobile communication system that supports packet services, in order to improve the utilization of system resources and increase the throughput of the system, the base station needs to adjust the resources used to send service data, such as time resources and frequency resources, according to channel quality and other factors. After the service data resources are allocated, the base station and the user terminal need to switch from the originally used resources to the newly allocated resources. For example, for packet service data with small packets, such as uplink Voice over IP (VoIP, Voice over IP) services, the resources for transmitting service data are often adjusted through quasi-static scheduling. Here, quasi-static has two meanings: One...
