Embodiment 1

[0044] A preferred embodiment of the present invention provides a method for enhancing the preamble detection processing capability of a WCDMA system, such as Figure 4 As shown, the method includes the following steps:

[0045] S402. Obtain a corresponding preamble detection instruction according to the preamble sent by the UE in the WCDMA system;

[0046] S404. According to the obtained preamble detection instruction, judge whether the detection task corresponding to the preamble detection instruction can be completed within a predetermined time; specifically, in the protocol in the field of communication, relevant provisions are made on the time parameter of preamble detection, For example, requiring τ p-a ≤7680chips, etc., in the specific operation process, the time parameter specified in the agreement can be used as the predetermined time for judgment. Preferably, the performance of the detection task corresponding to the preamble detection instruction can be predicted ...

Embodiment 2

[0056] Based on the method for enhancing the preamble detection processing capability of the WCDMA system provided in Embodiment 1 above, a preferred embodiment of the present invention also provides a device for enhancing the preamble detection processing capability of the WCDMA system, specifically, as Figure 8 As shown, the device includes:

[0057] The acquiring unit 802 is configured to acquire a corresponding preamble detection instruction according to the preamble sent by the UE in the WCDMA system;

[0058] The judging unit 804 is configured to judge whether the detection task corresponding to the preamble detection instruction can be completed within a predetermined time according to the obtained preamble detection instruction; specifically, in the protocol in the communication field, the time parameter of the preamble detection is determined. Related regulations, for example, require τ p-a ≤7680chips, etc., in the specific operation process, the time parameter spec...

Embodiment 3

[0066] Based on the technical solutions provided in Embodiment 1 and Embodiment 2 above, this preferred embodiment provides a specific method for enhancing the preamble detection and processing capability of the WCDMA system, Figure 9 Show a kind of preferred flowchart of above-mentioned method, as Figure 9 As shown, the method includes the following steps:

[0067] In step S901, the service layer sends the preamble detection signaling according to the application, mainly including the initial value of the X scrambling code, the access time slot, and the parameter information related to the cell and the frequency point.

[0068] Step S902, after the software layer receives the preamble detection signaling, according to the processing granularity of the hardware, decompose the signaling into multiple subtasks that the hardware can handle independently; at the same time combine the task history information maintained by the software layer (mainly including the start time of th...

Abstract

Disclosed are a method and a device for enhancing a preamble detection processing capability of a WCDMA system. The method comprises: acquiring a corresponding preamble detection instruction according to a preamble sent by a UE in a WCDMA system; determining, according to the acquired preamble detection instruction, whether a detection task corresponding to the preamble detection instruction can be completed in a preset time; and if it is determined that the detection task cannot be completed in the preset time, bringing the start time of the detection task in advance. The present invention effectively solves the problem in the related art that some UEs cannot access a base station due to increased delays in the case of remote optical fiber connection or in other circumstances, thereby enhancing the preamble detection processing capability of the WCDMA system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a device for enhancing the preamble detection and processing capability of a WCDMA system. Background technique [0002] In a Wideband-Code Division Multiple Access (WCDMA for short) system, access slots are pre-defined by the base station NodeB, and user equipment (User Equipment, UE for short) can be used to send access preambles or receive The time period of incoming messages. The access slot information is sent to the UE receiving the message in the form of system broadcast, and then the UE accesses the WCDMA system through a Physical Random Access Channel (PRACH for short) in the access slot. [0003] Before accessing the WCDMA system cell, the UE first randomly selects an available access slot and random signature, and sends a preamble (Preamble) to the base station through the PRACH with initial transmission power; the base station detects the preamble to ...
