Problems solved by technology

[0008] In the case of multiple carriers, the user terminal can randomly select a carrier to access, or pre-agreed with the network side to access a carrier, etc. When the load of the carrier selected by the user terminal is too heavy or the signal is not good, it will affect the The user terminal accesses the network, for example, the access may fail
On the other hand, since the base station cannot inform the user terminal of the carrier load status, the user terminal cannot select a carrier to access based on this information, which may cause a load imbalance between carriers for a long time

Embodiment Construction

[0028] In the embodiment of the present invention, in the case of multiple carriers, when the network side equipment (such as base station BS) paging user equipment (such as MS), it can carry the recommended access carrier information in the paging message, so that when the MS receives the paging After calling the message, it can re-enter the network according to the carrier recommended by the network side equipment; or when the terminal MS initiates an access request code word (RNG-Code) or an access request message (RNG-REQ Message), the base station BS can send the message in the response message It carries the recommended access carrier information, so that the MS can access the network according to the carrier recommended by the network side equipment after receiving the response message. Therefore, in the embodiment of the present invention, when the load of each carrier of the BS is unbalanced, the MS accesses from the carrier with a lighter load, so as to realize the pu...

Abstract

The invention discloses a multi-carrier access method, a system and equipment thereof. The method comprises the following steps: a user terminal receives a message sent by a network-side device; the message carries recommended carrier information; and the user terminal is connected into the network according to the recommended carrier information carried in the message. Under the condition with multiple carriers, when the invention is used and the user terminal accesses the network for the first time or access the network once again from the idle mode, the network-side device can control the user terminal to access the network on the set carrier in accordance with the set strategies.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, system and equipment for multi-carrier access. Background technique [0002] In the existing communication system, for the purpose of power saving, an idle mode is proposed. The idle mode of each standard may have different implementations, but they are essentially the same. Now take the IEEE802.16e standard as an example to introduce the idle mode. . In the idle mode, MS (Mobile Station, mobile station) can move in a large area and receive downlink broadcast service messages at regular intervals. During the roaming process of MS in this area, it is not necessary to transfer information from the roaming cell to this cell. BS (BaseStation, base station) performs registration. In the idle mode, when the MS roams to different cells, it does not need to perform normal operation procedures such as handover, which helps to save the power and air interface ...
