Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] In the following embodiments, the wireless communication system takes the LTE system as an example, but it can be generally applied in wireless communication systems. System messages in other wireless communication systems have different names, but the embodiments of the present invention can also be applied. In the following embodiments, the system message is a femtocell system message.

[0031] as attached figure 1 As shown, the first embodiment of the present invention provides a method for obtaining system information. The method includes:

[0032] Step 101, receiving the MIB sent by the femtocell.

[0033] In step 101, the UE receives the MIB sent by the femtocell, wherein the MIB is broadcast periodically according to the scheduling period specifie...

Abstract

The invention discloses a method for acquiring system messages, which comprises the following steps: receiving a system message block sent from a network side; and when a system message change tag contained in the received system message block indicates that the system messages are changed, acquiring the updated system messages. Simultaneously, the invention also discloses a device and a system for acquiring the system messages. By using a femtocell base station to broadcast all the system messages non-periodically, the invention can lower the system channel expense, reduce the intersystem interference, and lower the power consumption of the base station; and meanwhile, when the femtocell base station broadcasts all the system messages non-periodically, the invention can enable user equipment to establish wireless resource control connection by presetting the system messages and realize residence and connection establishment under a cell of the femtocell base station in a switching process.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method, device and system for acquiring system information. Background technique [0002] Femtocell base station (femtocell) technology is a solution to extend the indoor coverage of mobile communications. The femtocell is usually installed in a small environment, and users can use various mobile terminal devices to access the core network through the femtocell. The mobile terminal devices are, for example, mobile phones, personal computers or palmtop computers. Femtocell's home access point can be plug-and-play and can be connected to any existing Internet Protocol (IP)-based transmission network, so it can replace the fixed broadband access equipment of a home or small business and be called a home base station or an indoor base station . [0003] Femtocell is usually used in the network coverage of homes or small businesses, and the number of users generally does ...
