Problems solved by technology

Since the PCH data of 4 subframes needs to be received each time, the receiving time is longer, which in turn affects the longer time for the UE to perform paging processing, consumes the power of the UE, and shortens the standby time

Embodiment Construction

[0071] The basic idea of ​​the present invention is: when receiving PCH data, after continuously receiving the PCH data of the first L (0<L<N, and L is an integer) subframes in the N subframes included in a complete TTI, the receiving Despread and demodulate the PCH data of the received L subframes to obtain bit-level data; after that, add data of N-L subframes with all 0 bits, decode the added bit-level data, and then adapt Sex paging processing.

[0072] Hereinafter, the implementation of the paging processing method and device of the present invention will be described in detail through specific embodiments in conjunction with the accompanying drawings.

[0073] Figure 5 It is a schematic flow chart of the paging method of the present invention, since currently one TTI generally includes 4 subframes, therefore, in Figure 5 In the shown method, a case where a complete TTI includes 4 subframes is used as a specific embodiment for description. Such as Figure 5 As shown,...

Abstract

The invention provides a processing method during paging process. The method comprises the following steps of correspondingly receiving the PCH data of first L (L is less than N and more than 0 and is an integer) sub-frames out of N sub-frames contained in a TTI when the UE determines to receive PCH data, obtaining bit data by de-spreading and demodulating the data, subsequently adding the data with N-L sub-frames and all 0 in each bit behind the bit data, and coding the added bit data subsequently. The invention provides a device for realizing paging simultaneously. The method and the device can shorten the time for receiving the PCH data before coding, thus shortening the time of paging processing carried out by the UE.

Description

technical field [0001] The present invention relates to paging technology, in particular to a processing method and device in paging. Background technique [0002] A terminal (UE) has two basic modes of operation: idle mode and connected mode. After power-on, the UE stays in the idle mode and is distinguished by non-access stratum identifiers such as customer identification code (IMSI), temporary subscriber identification code (TMSI), or packet-TMSI (P-TMSI). [0003] After the UE camps in the cell, it will be in the idle mode most of the time, that is, in the standby state. At this time, the UE only needs to adopt the discontinuous reception (DRX) mode, and in each discontinuous reception cycle, decode the paging indication channel (PICH) data of a radio frame, and then judge whether it needs Process the corresponding paging channel (PCH), and then get paging information, or go to sleep mode again. [0004] In the following, the channel content and composition structure ...
