Embodiment 1

[0052] Please refer to figure 1 , an embodiment of the present invention provides a method for obtaining system information, including:

[0053] 101. The user equipment sends a request message for requesting a femtocell system message to the network side;

[0054] 102. Receive a response message returned by the network side, where the response message carries system information of the femtocell.

[0055] In this embodiment, the user equipment actively sends a request message to request the system information of the femtocell from the network side, and the network side does not need to periodically broadcast the system message, but only needs to reply with a message carrying the system information of the femtocell upon receiving the request message from the user equipment. It only needs to send a response message to the user equipment. Therefore, the occupation of the broadcast channel can be avoided, the overhead of the broadcast channel can be reduced, the interference betw...

Embodiment 2

[0065] Please refer to figure 2 , an embodiment of the present invention provides another method for obtaining system information of a micro base station, including:

[0066] 201. After receiving the master information block broadcast by the femtocell, the user equipment sends a connection establishment request message to the femtocell.

[0067] When the user equipment moves from one location area to another location area, after executing the location area update process, the femtocell in the new location area will know the camping information of the user equipment. The femto base station may broadcast the MIB on the broadcast channel after learning that the user equipment is camped on, the MIB includes connection information and indication information, and the indication information is used to indicate whether the base station is a femto base station. After receiving the MIB broadcast by the femtocell, the user equipment can initiate a connection establishment process accor...

Embodiment 3

[0073] The technical solution described in the first and second embodiments above can be used for the user equipment to obtain the system information of the femtocell for the first time, but in the subsequent operation process, the system information of the femtocell may change. This embodiment aims at this situation, The following solutions are proposed:

[0074] One solution is that when its own system information changes, the femto base station actively generates a paging message, carries the changed system information in the paging message, and sends the paging message to the user equipment, and the user equipment receives the paging message from the femto base station The paging message is sent to obtain the system message after the femtocell changes. Wherein, the femtocell may separately generate a paging message for each user equipment in the cell, that is, individually page each user equipment. If the user equipment leaves the cell of the femtocell and needs to pass t...

Abstract

The invention discloses a method and device for obtaining system messages of miniature substations. The method includes: a user device transmits request messages for requesting the system messages of the miniature substations to a network side and receives responding messages returned by the network side, wherein the responding messages contain the system messages of the miniature substations. By means of the technical scheme, the user device requests and obtains the system messages of the miniature substations by transmitting request messages to the network side, a macro substation or a miniature substation of the network side do not need to broadcast the system messages, accordingly, expenditure in broadcast channels of the miniature substations can be reduced, interference within systems is reduced, and power consumption of the miniature substations is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for acquiring system information of a micro base station. Background technique [0002] In a wireless communication system, most of the wireless communication services are generated by indoor users, while traditional macro base stations cannot provide good wireless signal coverage for indoor and other small and complex environments. In order to solve the above problems, micro base stations, such as femto base stations or femto base stations, which can be specially used in small and complex environments such as indoors, have emerged. As the secondary base station of the macro base station, the micro base station can be arranged by users in small and complex environments such as indoors, and provides users with high-speed indoor wireless access in a simple and cheap way. In a macro base station cell, many micro base stations can be arranged base ...
