Problems solved by technology

However, all current user equipments only support FDD as the primary carrier and TDD as the secondary carrier
When user equipment camps on a cell in the TDD frequency band and uses TDD as the primary carrier, it is no longer possible to use carrier aggregation technology to configure a cell in the FDD frequency band as a secondary cell, and use FDD as a secondary carrier, and it is impossible to use TDD and FDD carriers together. Data transmission, but only in the state of single-carrier data transmission, unable to effectively use network resources to increase the transmission rate

Embodiment 1

[0024] An embodiment of the present invention provides a method for user equipment to access a carrier aggregation network, which is applied to a base station, such as figure 2 shown, including:

[0025] Step 101. Receive a first message sent by a user equipment.

[0026] The first message includes the capability of the user equipment, and the capability of the user equipment is used to indicate that the user equipment supports a frequency division duplex FDD frequency band and a time division duplex TDD frequency band, and the user equipment is registered in the first cell, The first cell is a cell in the TDD frequency band.

[0027] Step 102, judging that the load value of the second cell is less than or equal to a threshold value.

[0028] The second cell is a cell in the FDD frequency band, the coverage of the first cell is within the coverage of the second cell, and the priority of the first cell is higher than that of the second cell.

[0029] Step 103: Send a handov...

Embodiment 2

[0033] An embodiment of the present invention provides a method for user equipment to access a carrier aggregation network, which is applied to such as figure 1 In the carrier aggregation network shown, it is assumed that the cell within the coverage of the eNB is the first cell, and the first cell is the primary cell, and the cell of the micro base station within the coverage of the eNB is the second cell, and the second cell is the secondary cell, as shown in image 3 As shown, the method includes:

[0034] Step 201, user equipment 1 sends a registration request to eNB.

[0035] User equipment 1 enters an area where the coverage of the first cell and the coverage of the second cell overlap, and since the priority of the first cell is higher than the priority of the second cell, the user equipment sends a registration request to the eNB, and the The registration request includes the cell number of the first cell, and is used to request the eNB to register with the first cell...

Embodiment 3

[0057] An embodiment of the present invention provides a user equipment 30, such as Figure 4 shown, including:

[0058] The receiving unit 301 is configured to receive a first message sent by the user equipment, the first message includes the capability of the user equipment, and the capability of the user equipment is used to indicate that the user equipment supports frequency division duplex FDD frequency band and time division A duplex TDD frequency band, the user equipment is registered in a first cell, and the first cell is a cell in the TDD frequency band;

[0059] The processing unit 302 is configured to determine that the load value of the second cell is less than or equal to a threshold value, the second cell is a cell in the FDD frequency band, and the coverage of the first cell is within the coverage of the second cell, so The priority of the first cell is higher than the priority of the second cell;

[0060] A sending unit 303, configured to send a handover inst...

Abstract

Embodiments of the invention provide a method for user equipment to access a carrier wave aggregation network and an apparatus and relate to the communication field. A network resource can be effectively used to increase a transmission rate. The method comprises the following steps of receiving a first message sent by user equipment, wherein the first message comprises a user equipment capability; the user equipment capability is used to indicate the user equipment to support a frequency division duplex FDD frequency range and time division duplex TDD frequency range; the user equipment is registered in a first cell and the first cell is a cell of the TDD frequency range; determining that a load value of a second cell is less than or equal to a threshold value, wherein the second cell is a cell of FDD frequency range; a coverage range of the first cell is within a coverage range of the second cell and a priority of the first cell is higher than a priority of the second cell; sending switching indication to the user equipment, wherein the switching indication is used for indicating the user equipment to be switched to the second cell; and sending a configuration message to the user equipment, wherein the configuration message is used for indicating the user equipment to configure the first cell. The method and the apparatus are used for accessing the carrier wave aggregation network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for user equipment to access a carrier aggregation network. Background technique [0002] With the continuous improvement of user data requirements, operators need to continuously improve network capacity and expand coverage to meet user needs through communication technologies. At present, operators are deploying frequency division duplex (English full name: Frequency Division Duplexing, English abbreviation: FDD) network and time division duplex (English full name Time Division Duplexing, English abbreviation: TDD) network, usually using carrier aggregation (English full name: Carrier Aggregation (English abbreviation: CA) technology integrates FDD network and TDD network to provide users with more abundant spectrum resources to improve network capacity and expand coverage to meet user needs. Since the FDD frequency band is much lower than the TDD frequenc...
