Embodiment 1

[0045] The system message broadcast sent by the base station to the cell where the user equipment is located carries part of aggregated information of the cell where the user equipment is located, specifically, the SIB of the system message broadcast carries part of the aggregated information of the cell where the user equipment is located. The user equipment can obtain part of the aggregation information of the cell it is in from the SIB.

[0046] For example, the SIB carrying part of the aggregated information of the cell where the user equipment is located is specifically: adding spectrum indication information to SIB1 to indicate whether the cell where the user equipment is located is an aggregated cell. If the cell is an aggregated cell, the user equipment needs to read other aggregated information. SIB, for example, a dedicated SIB* carrying aggregation information or adding other aggregation information to an existing SIB, so as to obtain other aggregation information of...

Embodiment 2

[0056] The system information broadcast sent by the base station to the cell where the user equipment is located carries all the aggregation information of the cell where the user equipment is located, specifically, the SIB of the system information broadcast carries all the aggregation information of the cell where the user equipment is located. The user equipment can obtain all the aggregation information of the cell it is in from the SIB.

[0057] Such as figure 2 Shown is the process of establishing an RRC connection between the user equipment and the target cell. During the process of establishing the RRC connection between the user equipment and the target cell, the RRC connection establishment message sent by the base station to the user equipment carries all aggregation information of the target cell.

[0058] Such as image 3 As shown, the handover command sent by the source base station to the user equipment when the user equipment is handed over to the target cel...

Embodiment 4

[0072] In this embodiment, the method for the user equipment to receive and deliver the message includes:

[0073] The user equipment receives the system information broadcast sent by the base station to the cell where the user equipment is located, and the system information broadcast carries all aggregated information of the cell where the user equipment is located, or the user equipment receives Dedicated downlink signaling sent by the device, where the dedicated downlink signaling carries all aggregation information of the target cell. The downlink dedicated signaling here includes an RRC connection establishment message and a handover command.

[0074] The method for user equipment to receive and send a message in the embodiment of the present invention can realize that the user equipment can obtain the aggregated information of the aggregated cell before receiving service in the aggregated cell by receiving the message carrying the aggregated information of the serving c...

Abstract

The invention discloses a method and a system for issuing messages to user equipment, and a method and a device for receiving the issued messages, relating to communication technique, and being capable of solving the problem that the user equipment can not get the aggregation information of a target cell before an aggregation cell accepts service in the prior art. The method for issuing messages to the user equipment comprises the step that a base station issues messages to the user equipment, wherein, the message carries the aggregation information that the user equipment receives a service cell. The system for issuing messages to the user equipment comprises a message sending unit for issuing messages to the user equipment, and a message carrying unit for carrying the aggregation information of a cell in the messages sent to the user equipment. The invention is suitable for providing service for the user equipment in the aggregation cell.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to sending and receiving messages in wireless communication. Background technique [0002] The four new frequency bands of the third-generation and fourth-generation mobile communication systems designated by ITU (International Telecommunications Union) are 200MHz bandwidth from 3.4G to 3.6GHz, 100MHz bandwidth from 2.3G to 2.4GHz, and 698M 108MHz bandwidth of ~806MHz and 20MHz bandwidth of 450M~470MHz. However, due to the different allocation of these frequency bands in different countries, the IMT (International Mobility Telecommunication) frequency bands that each operator finally obtains may not be continuous. Therefore, in order to ensure the service quality of high-bandwidth and high-speed services, spectrum aggregation The technology is introduced into the LTE-A system (Long Term Evolution-Advanced System). Spectrum aggregation technology can be applied to contiguous ...
