Embodiment 1

[0056] Embodiment 1, when the current serving base station is a macro base station, the base station selection method when the macro base station and the home base station are switched, the process is as follows image 3 As shown, the details are as follows:

[0057] (1.1) The macro base station first detects the received signal strength S fed back from the mobile terminal mserving , when detecting S mserving less than the preset threshold S mthreshoid , or a detection time period T 0 Complete, then trigger the handover and enter step (1.2); otherwise wait until a detection cycle is reached, or the signal strength S of the macro base station currently received by the mobile terminal mserving less than the first signal strength threshold S mthreshoid , enter step (1.2); in an embodiment, the first signal strength threshold S mthreshoid -95dBm;

[0058] (1.2) Detect the signal strength of each adjacent macro cell, and feed back to the serving base station, and then enter s...

Embodiment 2

[0071] Embodiment 2, when the current serving base station is a home base station, a method for selecting a base station when switching between a macro base station and a home base station, the process is as follows Figure 4 As shown, the details are as follows:

[0072] (2.1) First, the home base station judges the signal strength S fed back from the mobile terminal fserving Is it less than the second signal strength threshold S fthreshold , if so, trigger switching and enter step (2.2);

[0073] If not, wait until the signal strength S of the home base station currently received by the mobile terminal mserving is less than the second signal strength threshold, enter step (2.2);

[0074] In the embodiment, the second signal strength threshold S fthreshold -95dBm;

[0075] (2.2) Detect the signal strength of adjacent macro cells, and feed back to the serving base station, and enter step (2.3);

[0076] (2.3) measure the moving speed V of mobile terminal, if this speed i...

Abstract

The invention discloses a base station selection method used in the switching process of a micro base station and home base stations. The base station selection method particularly comprises the following steps of: combining a detection period and current received signal strength of a mobile terminal with trigger switching; when the detection period and / or the current received signal strength of the mobile terminal meet a trigger condition, selecting a to-be-accessed target base station type according to a moving speed, a user type, a service type and a non-CSG (Content Service Gateway) user on a CSG user; and selecting a base station with the highest signal strength from the target base station type, and using the selected base station as a target base station. By adopting the base station selection method provided by the invention, the advantages of the home base stations can be sufficiently played, and the home base stations are enabled to share a load of the micro base station to the greatest extent, so that throughput of an integral network and communication quality of users are improved; and on the other hand, the accessed base station is selected according to the moving speed of the mobile terminal, so that useless switching caused when the mobile terminal moving at a high speed frequently crosses between home base station cells is avoided.

Description

technical field [0001] The present invention belongs to the technical field of mobile communication, and more specifically relates to a method for selecting a base station when switching between a macro base station and a home base station. Background technique [0002] In recent years, with the integration of the Internet into people's lives, the demand for broadband applications has become increasingly strong. In the mobile network, home base stations and macro base stations are used together to solve the problem of poor indoor signal coverage due to the loss caused by walls in mobile services, as well as the contradiction between base station coverage radius, user capacity and available bandwidth for each user, and make full use of spectrum resources , improve the throughput of the entire communication network and the user experience of calling and surfing the Internet. [0003] Due to the mixed use of macro base stations and femtocells, seamless handover between macro b...
