Embodiment Construction

[0081] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0082] In the technical solution of the embodiment of the present invention, if the segmented information block of the BCH defined in the 3GPP specification is not the first segment, that is, the first received segmented information block is not the first Blocking, or in the case of continuously received segments, that is, information blocks with CRC errors leading to discontinuous reception, by caching the received blocks, the complete segmented blocks can be received in the shortest time.

[0083] In the process of realizing the present invention, the inventor found that the key to reorganization of each segment is the length of the first segment by analyzing the structure of each segment of a system message containing multiple segments. There are t...

Abstract

The invention provides a method for reading a broadcast channel through a terminal and the terminal. The method comprises the following steps: step A, a fragment of a system message is read, and the system message comprises a plurality of fragments; step B, the storage position of a read fragment in a buffer zone is defined according to an index of the read fragment, and the fragment is stored into the storage position; step C, the step A is executed if the reading process of all the fragments of the system message is not accomplished; otherwise the flow is stopped. The terminal comprises a broadcast channel reading module and the buffer zone, and the broadcast channel reading module comprises a reading module, a memory module and a continuous reading module. The terminal can realize the disordered reading of the system massage with a plurality of fragments through utilizing the technical proposal, therefore, more system massages can be read in a shorter period of time, the time span for reading the system massage required by the residence is reduced, and the power consumption of the terminal is reduced.

Description

technical field [0001] The present invention relates to a third-generation mobile communication system, in particular to a method for a terminal to read a broadcast channel (BCH, Broadcast Channel) and the terminal. Background technique [0002] At present, mobile communication is gradually evolving from the second generation mobile communication system to the third generation mobile communication system (the3rd Generation, 3G). The power consumption of 3G terminals such as Universal Mobile Telecommunication System (UMTS, Universal Mobile Telecommunication System) terminals has become a big problem. question. Since the terminal is in the idle state most of the time, how to improve the power saving performance of the terminal such as a mobile phone in the idle state and prolong the standby time of the terminal has become an urgent problem to be solved. [0003] One of the main activities in the idle process is cell reselection, and the relatively long time for cell reselecti...
