Problems solved by technology

[0009] The main purpose of the present invention is to provide a control scheme for starting compressed mode, so as to at least solve the problems caused by the different combinations of downlink carriers and uplink carriers used by the UE when inter-frequency measurements or inter-system measurements are required in the above-mentioned related technologies. Problems that cause the system to drop calls

Embodiment 1

[0088] In this preferred embodiment, an implementation of a control method for starting a compressed mode is provided, Figure 4 It is a schematic flowchart of the control method for starting the compressed mode according to the preferred embodiment 1 of the present invention, as shown in Figure 4 As shown, the flow mainly includes the following processing (step S402-step S406):

[0089] Step S402, the UE reports the multi-carrier frequency measurement capability to the network side. For example, the RNC on the network side may acquire the multi-carrier frequency measurement capability of the UE and perform corresponding control.

[0090] In the specific implementation process, the network side can obtain the multi-carrier frequency measurement capability of the UE in two ways: Method 1, the network side sends a multi-carrier frequency measurement capability query command to the UE, and the UE sends the multi-carrier frequency measurement capability query command to the netw...

Embodiment 2

[0100] Figure 5 is a schematic flowchart of a method for transmitting UE multi-carrier frequency measurement capability according to the second preferred embodiment of the present invention, as shown in Figure 5 As shown, the method includes the following steps:

[0101] In step S502, the UE needs to establish a connection with the RNC (that is, the network side), and initiates a radio resource control connection request (RRC Connection Request) message.

[0102] In step S504, the RNC allocates resources in the RRC phase, and sends a radio resource control connection establishment (RRC Connection Setup) message to the UE.

[0103] In step S506, the UE successfully establishes the connection, and sends a radio resource control connection setup complete (RRC Connection Setup Complete) message to the RNC, wherein the message carries the above-mentioned UE multi-carrier frequency measurement capability indication information element.

Embodiment 3

[0105] Image 6 is a schematic flowchart of a method for transmitting UE multi-carrier frequency measurement capability according to preferred embodiment 3 of the present invention, as shown in Image 6 As shown, the method includes the following steps:

[0106] In step S602, the RNC needs to acquire the multi-carrier frequency measurement capability information of the UE, and initiates a multi-carrier frequency measurement capability information query (UE Capability Enquiry) request to the UE.

[0107] In step S604, the UE sends its multi-carrier frequency measurement capability to the RNC through a UE capability information (UE Capability Information) message, and the message carries the UE multi-carrier frequency measurement capability indication information element.

Abstract

The present invention provides a method and a system for controlling start of a compressed mode. The method comprises the following steps: when User Equipment (UE) performs an inter-frequency measurement or an inter-system measurement, the UE determines that a network side indicates the UE not to start the compressed mode, according to a measurement control message received from the network side (S102); for N downlink auxiliary carriers of the downlink auxiliary carriers other than the downlink auxiliary carriers corresponding to the uplink auxiliary carriers, the UE does not start the compressed mode, wherein N is greater than or equal to 1 (S104). The present invention ensures continuity of calls, increases utilization ratio of system resources and improves system performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a control method and system for starting a compressed mode. Background technique [0002] In the existing cellular mobile communication system, in order to improve the utilization rate of spectrum resources and the capacity of the whole system, the transmission power of the base station in the system is limited within the cell. When the user equipment (User Equipment, referred to as UE) moves from a cell In the process of going to another cell, the signal of the source cell received by the UE must become weaker and weaker, and the signal of the entering cell (ie, the target cell) received by the UE will also become stronger and stronger. In order to maintain the communication quality of the UE, the UE needs to be handed over to a new cell. [0003] In the Frequency Division Multiplex (FDD for short) mode, in order to perform inter-frequency handover, FDD to Time Division Multip...
