Embodiment Construction

[0012] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0013] In the embodiment of the present invention, the existing PCI information is redefined. As shown in Table 1, the PCI in the prior art includes the identification fields of the macro cell and the HNB. In the embodiment of the present invention, the HNB identification field of the PCI is further It is divided into identification fields of CSG HNB and Open HNB, and the specific division of HNB identification fields is not limited in the present invention, and technicians can divide according to actual needs.

Abstract

The embodiment of the invention discloses an information acquisition method, which comprises the step of dividing a home base station HNB identification field contained in a physical cell identifier PCI into identification fields of a closed subscriber group home NodeB CSG HNB and an open home NodeB Open HNB. The method further concretely comprises the steps of: acquiring the PCI of an adjacent cell and confirming the type of the adjacent cell according to the PCI; and acquiring a system broadcast message of the adjacent cell according to the type of the adjacent cell and access constraint information of a terminal. The embodiment of the invention also provides the terminal. The method and the terminal can shorten the measuring time of the terminal and reduce the power consumption of the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information acquisition method and terminal. Background technique [0002] With the rapid development of mobile communication technology, there are more and more mobile communication systems, and the system equipment is also diversified in order to meet the needs of users. Home indoor coverage and enterprise-level internal coverage base stations, as well as some other restricted networks should be used. And born. Such a network may be a home base station (HNB, Home NodeB), a home cell, etc., as well as a limited network of certain specific frequency layers. Among them, HNB is further divided into HNB of closed subscriber group (CSG) and open HNB (Open HNB). The user is allowed to normally reside and apply for services in the CSG HNB. From the perspective of the network, a CSG may contain one cell or multiple cells, and users who have not subscribed and have not been added t...
