Problems solved by technology

[0006] According to the paging status of the user terminal, the home base station pages the user by sending a paging message on the air interface. For each paged user terminal, the home base station must send a paging message separately, which causes the paging channel transmission high cost

Embodiment Construction

[0027] In order to reduce the paging channel transmission overhead, the following technical solutions are adopted in the embodiments of the present invention.

[0028] In the embodiment of the present invention, the home base station uses the extended paging indication bitmap to indicate whether each user terminal is paged and the reason for being paged. The home base station sends an extended paging indicator bitmap in each paging cycle, which contains the paging indicator information of all user terminals served by the home base station. The paging indicator information of each user terminal includes N bits, and each page The instruction information can express a total of 2 N Paging state, in 2 N One value reserved among the values ​​indicates that there is no paging message, the other 2 N -1 values ​​respectively indicate different paging reasons. Each user terminal corresponding to the home base station has a user short identifier, and the user short identifier corresponds to...

Abstract

The embodiment of the invention discloses a paging method, device and communication system in a Femtocell system; the Femtocell generates an extended paging instruction bitmap including paging instruction information according to paging state of the user terminal, and sends the extended paging instruction bitmap. The user terminal receives the extended paging instruction bitmap including the paging instruction information, and obtains the paging instruction information which corresponds to the existing user terminal from the extended paging instruction bitmap, and response is given according to the paging state showed by the obtained paging instruction information. Through the technical scheme provided by the embodiment of the invention, the Femtocell does not need to respectively send paging information to each served user, therefore, the spending of resource transmission is saved.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a paging method, device and communication system in a home base station system. Background technique [0002] In mobile communication systems, in addition to the macro base stations deployed by operators, there is another base station form: small base stations, generally called access points (AP, Access point), which are characterized by coverage It is small and flexible in installation, and can be used in homes or small offices, called home base stations (HNB, Home NodeB). The coverage area of ​​the home base station is small and it serves fewer user terminals. [0003] Home base stations include CSG (Closed Subscriber Group, closed user group) base stations and OSG (Opened Subscriber Group, open user group) base stations. CSG base station only allows authorized user terminals to access, usually CSG base station supports a small number of user terminals; OSG base station allows un...
