Embodiment 1

[0055] In this embodiment, the advanced terminal determines that area switching is required as an example for description. figure 2 The flow chart of this embodiment, such as figure 2 As shown, the implementation process of this embodiment mainly includes the following steps:

[0056] In step 201, the advanced terminal selects one of its own channel carriers to send a ranging request message (AAI-RNG-REQ) to the first area of ​​the advanced base station, where the ranging request message may carry area conversion request information (for example, ranging The destination indicator bit is set to 4), and the above-mentioned area conversion request information may not be carried.

[0057] Specifically, the channel carrier selected by the advanced terminal may be, but is not limited to, one of the following: the current main carrier of the terminal, other channel carriers that maintain communication with the advanced base station, and idle channel carriers that are not currently used b...

Embodiment 2

[0062] In this embodiment, the advanced base station determines that it needs to perform area switching (that is, the advanced base station actively sends a message indicating the carrier information of the second area) as an example for description. image 3 The flow chart of this embodiment, such as image 3 As shown, the implementation process of this embodiment mainly includes the following steps:

[0063] Step 301: The advanced base station actively sends ranging response information (AAI-RNG-RSP) to the advanced terminal on the primary carrier of the terminal in the first area. The ranging response message includes at least one of the following information: the time offset between the first area and the second area, the channel carrier information used by the terminal to perform area conversion, other system information in the second area of ​​the base station, and whether the conversion is in progress. Instructions to maintain communication with the first area. The message...

Embodiment 3

[0067] In this embodiment, the advanced base station determines that it needs to perform area switching (that is, the advanced base station actively sends a message indicating the carrier information of the second area) as an example. The difference from the second embodiment is that the base station sends a handover command message Carrying the carrier information of the second area.

[0068] Figure 4 The flow chart of this embodiment, such as Figure 4 As shown, the implementation process of this embodiment mainly includes the following steps:

[0069] Step 401: The advanced base station actively sends a handover command message (AAI-HO-CMD) to the advanced terminal on the primary carrier of the terminal in the first area. The handover command message includes at least one of the following information: the time offset between the first area and the second area, the channel carrier information used by the terminal to perform area switching, preamble sequence information, other sy...

Abstract

The invention discloses a zone transferring method and a zone transferring system. For an advanced terminal working in a first zone of an advanced base station, the method comprises the following steps that: in the first zone, the advanced base station sends a message to the advanced terminal, wherein the message indicates the carrier information of a second zone of the advanced base station; and the advanced terminal switches from the first zone to the second zone according to the carrier information of the second zone, which is indicated by the message. The zone transferring effect can be improved by the method.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, and in particular to a method and system for area conversion. Background technique [0002] Currently, wireless communication systems use electromagnetic waves to communicate with mobile or fixed wireless communication terminals. When performing wireless communication, the terminal is usually located within the wireless coverage area of ​​the system and communicates with the system through a wireless communication channel. The wireless communication channel divides the electromagnetic wave frequency into multiple carrier frequencies, and one carrier frequency is one wireless communication channel. The wireless communication system uses a designated wireless channel to provide wireless coverage in a certain geographic area through a base station (Base Station, referred to as BS), and this geographic area is called a cell. Usually, the base station is located in the center of the...
