Problems solved by technology

[0007] Applying the above method can use multiple carriers / cells for data transmission, but because the environment where the user terminal is located may change at any time, and correspondingly, the quality of the carrier frequency may also vary with the However, the existing technical solutions do not provide a method for adjusting the carrier frequency according to the change of the carrier frequency quality, which affects the optimization of the network quality

Embodiment 1

[0030] Such as figure 1 As shown in the first embodiment of the present invention, a schematic flow chart of a carrier frequency control method in a multi-carrier / cell system includes the following steps:

[0031] Step S101: Establish a multi-carrier / cell connection between the terminal UE and the network.

[0032] Establish a multi-carrier / cell connection with one or two uplink carrier frequencies through two downlink carrier frequencies.

[0033] When the above-mentioned multi-carrier / cell connection is established through two downlink carrier frequencies and one uplink carrier frequency, a Fractional Dedicated Physical Channel (F-DPCH) is established on the downlink carrier frequency corresponding to the uplink carrier frequency. The power of the uplink physical channel is controlled, and data is transmitted through the High-Speed ​​Down Share Channel (HS-DSCH); the data is transmitted through the HS-DSCH on the remaining downlink carrier frequency.

[0034] For a detailed descript...

Embodiment 2

[0059] In order to explain the technical scheme of the present invention in detail, such as figure 2 As shown, the following describes the establishment of a multi-carrier / cell connection between the terminal UE and the network through the second embodiment of the present invention.

[0060] A cell with multi-carrier / cell capability will broadcast its own multi-carrier / cell capability or multi-carrier / cell coordination capability. For example, Node B is configured with 3 frequency points, and each frequency point has 2 cells. These cells are different The cells of the carrier frequency can all cooperate. A terminal UE with multi-carrier / cell capability will report its capabilities in a radio resource control (Radio Resource control, RRC) connection establishment request (in this embodiment, the RRC connection setup request message is taken as an example), and the network UTRAN receives the terminal UE When the RRC connection setup request message is used to learn the multi-carri...

Embodiment 3

[0083] Such as image 3 As shown, through the third embodiment of the present invention, the process of determining the deactivated carrier frequency is described in detail, including the following steps:

[0084] Step S301: The terminal UE receives the carrier frequency report condition.

[0085] This message specifies the signal volume of the measurement, when to start the measurement, when to stop the measurement, the measurement conditions, and the reporting time of the measurement results.

[0086] Step S302: The terminal UE reports the CQI information of the carrier frequency to the Node B.

[0087] In this step, it is necessary to specify the method for reporting the measured value of the deactivated carrier / cell of the terminal UE to the NodeB and which own measurements the NodeB can use to obtain information such as the quality and power of the radio link of a certain carrier / cell. At present, the terminal UE reports the CQI in the High-Speed ​​Dedicated Physical Control Chan...

Abstract

The embodiment of the invention discloses method and equipment for establishing connection between a terminal and a network. The method comprises the following steps: the network receives multi-carrier / community ability information sent by the terminal; and according to the multi-carrier / community ability information, the network and the terminal establish multi-carrier / community connection. According to the technical scheme, the network can obtain the multi-carrier / community ability information of the terminal and establish the multi-carrier / community connection with the terminal according to the multi-carrier / community ability information of the terminal.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and equipment for establishing a connection between a terminal and a network. Background technique [0002] Existing High-Speed ​​Packet Access (HSPA) systems are all carried on a single frequency point. In order to further increase the data transmission rate of the HSPA system, reduce delay and improve user experience, a combination of multiple The scheme of bundling frequency points for carrying HSPA data is proposed. In this solution, two (or more) 5MHz carrier frequencies in the downlink direction will be bundled together for HSPA data transmission. The most important one is the bundling of two carrier frequencies. These two carrier frequencies can be regarded as frequencies used by two cells covering the same area, and the number of carrier frequencies used for uplink and downlink It can be the same or different, but generally there are more downlink...
