Embodiment 1

[0024] figure 1 It is a schematic flowchart of a method for a mobile terminal to access a wireless network provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the method for the mobile terminal to access the wireless network includes the following steps:

[0025] 101. The base station acquires a cognitive channel to be detected from a base station database according to preset detection conditions.

[0026] In this embodiment, preset detection conditions are set in the base station, and after the preset detection conditions are met, the base station can acquire the cognitive channel to be detected from the base station database. Specifically, after the preset detection condition is reached, the base station sends a query request to the base station database, and the base station database feeds back a query result to the base station, and the query result carries the cognitive channel to be detected.

[0027] 102. The base station acquires the curren...

Embodiment 2

[0040] figure 2 It is a schematic flowchart of another method for a mobile terminal to access a wireless network provided by an embodiment of the present invention. Such as figure 2 As shown, the method for the mobile terminal to access the wireless network includes the following steps:

[0041] 201. The base station detects whether a preset first period is reached.

[0042] 202. If the first period is reached, the base station acquires the cognitive channel in use from the base station database as the first cognitive channel to be detected.

[0043] In practice, the states of the cognitive channel at different times include: use state, standby state, occupied state and irrelevant state. The usage state indicates that the cognitive channel is being used by a mobile terminal accessed by the base station. The standby state means that the cognitive channel is idle for a period of time and can be accessed by the base station to the mobile terminal. The occupied state indica...

Embodiment 3

[0097] Figure 4 It is a schematic structural diagram of a base station provided by Embodiment 3 of the present invention. Such as Figure 4 As shown, the base station includes: a channel update management module 41 , a wireless access management module 42 and a base station database 43 .

[0098] Wherein, the channel update management module 41 is configured to obtain the cognitive channel to be detected from the base station database 43 according to preset detection conditions, obtain the current state of the cognitive channel to be detected, and use the current state of the cognitive channel to be detected The state updates the state corresponding to the cognitive channel to be detected in the base station database 43 .

[0099] The wireless access management module 42 connected with the base station database 43 is used to receive the access request sent by the mobile terminal, query the available channel for the mobile terminal from the authorized channel corresponding t...

Abstract

The invention provides a method and base station for a mobile terminal to have access to a wireless network. According to the method, the base station acquires a cognition channel to be detected from a base station data base according to a preset detection condition, acquires the current state of the cognition channel to be detected, and updates the state, corresponding to the cognition channel to be detected, in the base station data base by means of the current state of the cognition channel to be detected, the base station receives an access request sent by a terminal and inquires a usable channel for the mobile terminal from an authorization channel corresponding to an authorization frequency spectrum and the updated base station data base, and if the usable channel is found, data transmission is conducted between the base station and the mobile terminal by means of the usable channel. According to the method and base station, the current state of the authorization channel and the current state of the cognition channel are updated in real time, the base station can acquire the usable cognition channel for the mobile terminal directly after receiving the access request, and network access timeliness of the mobile terminal is improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for a mobile terminal to access a wireless network and a base station. Background technique [0002] With the continuous development of wireless communication technology, there are more and more wireless services, and users have higher and higher requirements for wireless transmission rates. In order to achieve a higher service rate, more spectrum resources will be occupied, so that the current wireless spectrum has become an increasingly scarce resource. [0003] The existing wireless spectrum usage rules are to allocate channels corresponding to fixed spectrum to different service types. In order to ensure the service quality of each service type, unauthorized service types cannot work in channels corresponding to spectrum allocated by other service types. In practice, because some service types cannot effectively use the channel resources corresponding to the allocated spe...
