Problems solved by technology

However, if the operator's public control channel bandwidth, such as the broadcast channel bandwidth is 2.5MHz, it cannot support communication with terminals capable of 1.25MHz bandwidth
[0008] When using the above method, although the LTE system can meet the requirements of terminals with various bandwidth capabilities to communicate in the system, since the common control channel bandwidth selected by the operator or / and the minimum bandwidth of the frequency band used cannot be known in advance, it is impossible After setting the bandwidth capability supported by the terminal, the terminal cannot know the bandwidth of the public control channel of the current LTE system or / and the minimum bandwidth of the frequency band used, which will cause terminals with different bandwidth capabilities to be unable to access the LTE system for communication, or Some terminals that do not meet the bandwidth capability of the common control channel of the LTE system or / and the minimum bandwidth capability of the frequency band used cannot communicate after accessing the LTE system

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings.

[0039]In order to ensure that a terminal that satisfies the bandwidth capability supported by the LTE system accesses the LTE system for communication, the terminal needs to obtain the bandwidth capability of the frequency band used by the current LTE system. The present invention proposes two solutions: the first solution, the LTE system Use system signaling to broadcast, and send the minimum bandwidth or / and public control channel bandwidth supported by the frequency band used by the LTE system to the terminal under the current jurisdiction of the LTE system through system signaling, and the terminal receives the minimum bandwidth carried by the system signaling message Or / and public control channel bandwidth to judge whether it has the b...

Abstract

The disclosed method to let terminals with different bandwidth capacity access wireless communication system comprises: terminal obtains the current bandwidth capacity of wireless system network side management area according to system signaling or the pre-set message, then hereby processes self bandwidth capacity to access the wireless system. This invention ensures the terminal with support capacity to access LTE system for communication.

Description

technical field [0001] The present invention relates to a technology for a terminal to access a wireless communication system, in particular to a method for terminals with different bandwidth capabilities to access a wireless communication system. Background technique [0002] Universal Mobile Telecommunications System (UMTS) is a third-generation mobile communication system that uses Wideband Code Division Multiple Access (WCDMA) air interface technology. With the development of the third-generation mobile communication system, in order to adopt high-speed wireless access technologies such as Worldwide Interoperability for Microwave Access (WiMAX) in UMTS, and maintain the vitality and competitiveness of the WCDMA / Global System for Mobile Communications (GSM) 3GPP standard, 3GPP has proposed the long-term evolution (LTE) of UMTS, and LTE mainly studies the evolution of UMTS access network. Currently, the physical layer of LTE is based on Orthogonal Frequency Division Multi...
