Problems solved by technology

[0007] The disadvantage of this processing is that when the set of configured carriers changes (for example, configured carriers are deleted to become unconfigured carriers, or unconfigured carriers are added to configured carriers), the configuration of related measurement events Need to make corresponding adjustments through RRC signaling
For example, if the carriers that can be aggregated in the carrier aggregation serving cell are CC1, CC2, and CC3, and the current network side only configures CC1 for the UE, then for CC1, use the measurement task of event A2, and for CC2 and CC3, use the measurement task of event A4 Measurement task, when the network side decides to configure CC2 to the UE, it needs to delete the measurement task of event A4 of CC2 and add the measurement task of event A2 of CC2, resulting in waste of air interface signaling

Embodiment 1

[0033] Such as figure 2 , 3 As shown, the UE resides in carrier aggregation cell 1, which is the serving cell of carrier aggregation and supports aggregation of three component carriers, CC1, CC2 and CC3. Carrier aggregation serving cells include CC1, CC2 and CC3.

[0034] After the UE initiates the service, the network side configures CC1 and CC2 for the UE as required, that is, the current user terminal simultaneously uses two component carriers, CC1 and CC2. CC1 and CC2 are configured component carriers, and CC3 is an unconfigured component carrier.

[0035] The base station configures the following measurement tasks for the user terminal through measurement configuration (included in the RRC connection reconfiguration signaling):

[0036] Measurement task 1: The signal strength of the carrier aggregation serving cell on the component carrier CC1 is lower than the specified threshold (A2 event on CC1);

[0037] Measurement task 2: The signal strength of the carrier aggre...

Embodiment 2

[0047] Such as Figure 4 , 5 As shown, the UE resides in carrier aggregation cell 1, which is the carrier aggregation serving cell and supports aggregation of three component carriers, CC1, CC2, and CC3. Carrier aggregation serving cells include CC1, CC2, and CC3.

[0048] After the UE initiates a service, the network side configures CC1 and CC2 for the UE as required, that is, the current user terminal uses two component carriers, CC1 and CC2, at the same time. CC1 and CC2 are configured component carriers, and CC3 is an unconfigured component carrier.

[0049] The base station configures the following measurement tasks for the user terminal through the measurement configuration (included in the RRC connection reconfiguration signaling):

[0050] Measurement task 1: The signal strength of the carrier aggregation serving cell on the component carrier CC1 is lower than the specified threshold (A2 event on CC1);

Embodiment 3

[0065] The UE resides in carrier aggregation cell 1, which is the serving cell of carrier aggregation and supports aggregation of three component carriers, CC1, CC2, and CC3. Carrier aggregation serving cells include CC1, CC2, and CC3.

[0066] After the UE initiates a service, the network side configures CC1, CC2, and CC3 for the UE, that is, the current user terminal uses three component carriers, CC1, CC2, and CC3 at the same time. CC1, CC2, and CC3 are all configured component carriers.

[0067] The base station configures the following measurement tasks for the user terminal through the measurement configuration (included in the RRC connection reconfiguration signaling):

[0068] Measurement task 1: The signal strength of the carrier aggregation serving cell on the component carrier CC1 is lower than the specified threshold (A2 event on CC1);

[0069] Measurement task 2: The signal strength of the carrier aggregation serving cell on component carrier CC2 is lower than t...

Abstract

The present invention provides a method of carrier management. A base station configures measurement tasks of carrier management for user equipment according to the signal quality of a carrier aggregation serving cell, wherein the carrier aggregation serving cell includes a carrier aggregation cell that is wirelessly connected to the user equipment. All component carriers of aggregation are supported. The invention also provides a carrier management system.

Description

technical field [0001] The invention relates to the technical field of digital mobile communication, and mainly relates to a carrier management method and system. Background technique [0002] In order to provide higher data rates for mobile users, Long Term Evolution Advance (LTE-A for short) proposes carrier aggregation technology (Carrier aggregation, CA for short). ) provides greater bandwidth and increases the peak rate of the UE. In LTE, the maximum downlink transmission bandwidth supported by the system is 20MHz, and carrier aggregation is to aggregate two or more component carriers (CC for short) to support a downlink transmission bandwidth greater than 20MHz, and the maximum does not exceed 100MHz. The above two or more component carriers are aggregated into one cell, which is called a carrier aggregation cell. The component carriers aggregated by multiple carrier aggregation cells will overlap, such as figure 1 As shown, the component carriers aggregated by carr...
