Embodiment 1

[0087] In the existing LTE system, when the UE detects that the channel quality of the current serving cell has deteriorated and cannot meet the communication needs, or the channel quality of other cells is better than that of the current cell, it will report the channel to the base station of the serving cell. measurement report. After receiving the measurement report, the base station of the local cell judges whether the UE needs to be handed over to another cell for service. If the base station of the local cell decides to hand over, it needs to send a handover request with the target handover cell first, and then send a handover command to the UE in the current cell after getting confirmation from the base station of the target cell. After receiving the handover command, the UE disconnects the data communication with the current cell, and starts to initiate a connection request to the target cell, where the connection request includes the uplink synchronization process, th...

Embodiment 2

[0111] The frequency mixing device is a device that can move the working frequency of the RF front-end to other frequencies. The frequency mixing device is often installed in the RF front-end of the existing equipment. The technical effect brought about by it is that the equipment thinks that it is still working on the original frequency, but the actual transmitted signal is moved to the new frequency. For example, a UE in an LTE system originally works at 2.3 GHz, and by installing a frequency mixing device on its radio frequency front end, the UE can actually work at 5 GHz, but the UE still thinks that it works at 2.3 GHz.

[0112] A frequency mixing device that can be controlled by software is added to the mobile communication access network equipment and the radio frequency front end of the mobile communication terminal. The mobile communication access network equipment sends a software command to adjust the frequency shift offset of the mixer, and the mobile communication ...

Embodiment 3

[0123] A new frequency adjustment command is defined, which is sent by the base station to the UE. After receiving the command, the UE stops communicating with the base station and adjusts its own radio frequency within a predetermined time. After the adjustment, the UE thinks that it is still It is connected to the base station and continues to communicate.

[0124] In this optional embodiment, the mobile communication access network device sends a radio frequency front-end readjustment command to the mobile communication user terminal operating at the first frequency, ordering the mobile communication terminal to adjust its radio frequency front-end to the second frequency, and the mobile communication access After confirming that the mobile communication terminal has received the RF front-end readjustment command, the network access device readjusts the RF front-end of the mobile communication access network device itself to the second frequency, and both the mobile communic...

Abstract

The invention discloses an information interaction method and device applied in a mobile communication system. The method comprises the following steps: access network equipment sends to a terminal a command used for notifying the terminal to carry out a working frequency adjustment; after the access network equipment confirms the receipt of the command by the terminal, the working frequency of the access network equipment is adjusted to a designated frequency; and the access network equipment carries out information interaction with the terminal at the designated frequency. The method and device provided by the invention has the advantages that the problem in the relevant art that dynamic frequency selection (DFS) is unavailable in an LTE system is solved, so that the effect that the DFS or frequency adjustment function is available in the mobile communication system is further achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an information interaction method and device applied in a mobile communication system. Background technique [0002] The mobile communication system refers to that operators provide communication services for user terminals (such as mobile phones) by deploying wireless access network equipment (such as base stations) and core network equipment (such as Home Location Register, HLR for short). system. Mobile communication has experienced the first generation, second generation, third generation, and fourth generation. The first generation of mobile communication refers to the initial analog, voice-only cell phone standard, which mainly uses analog technology and Frequency Division Multiple Access (FDMA) access method; the second generation of mobile communication Introduced digital technology, increased network capacity, improved voice quality and confidentiality, with "Global ...
