Problems solved by technology

[0009] However, since it is only an optional configuration, and the application of the extended estimation window will increase the network processing burden, so from the current situation, no network equipment manufacturer will configure the extended estimation window for the terminal.

Embodiment Construction

[0038] In order to make the purpose, steps and advantages of the present invention clearer, the present invention will be further described in detail below through the embodiments and with reference to the accompanying drawings.

[0039] The embodiment of the method for accessing the uplink enhanced random access channel of the mobile terminal provided by the present invention includes:

[0040] Step 1, when the authorization information for uploading data expires and the amount of buffered data in the logical channel of the mobile terminal is zero, start the timer;

[0041] Step 2, judging whether the timer is overtime, if the newly issued upload data authorization information is received before the timer overtime, reset the timer and initiate the E-RUCCH access;

[0042] Step 3, if the upload data authorization information is not received before the timer expires, reset the timer when the timer expires and determine whether there is cached data in the logical channel;

Abstract

The invention provides a mobile terminal and a method for accessing an enhanced-random uplink connection channel. The method comprises: when an uploaded data authorization message expires and the terminal cache data amount is zero, starting a timer; judging whether a timer overtimes; if the uploaded data authorization message is received before the timer overtimes, resetting the timer, and initiating the E-RUCCH (enhanced-random uplink connection channel) access; if the uploaded data authorization message is not received before the timer overtimes, resetting the timer when the timer overtimes, and judging whether cache data exist in the logic channel; and when the data amount in the logic channel exceeds the threshold value of the logic channel cache data, initiating the E-RUCCH access. The method and the terminal can control the E-RUCCH access time of the mobile terminal and avoids initiating unnecessary and frequent access.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal and an E-RUCCH access method. Background technique [0002] The development of mobile communication technology to the third generation (3G), the high speed uplink packet access (HSUPA) technology provides the uplink direction, that is, the direction from the mobile terminal to the wireless access network for packet services optimization and evolution. Using HSUPA technology, the peak transmission rate of uplink users can be greatly improved compared with the second generation (2G). HSUPA business is divided into scheduling business and non-scheduling business according to different scheduling methods. Among them, the resources of the non-scheduling service are mainly used to transmit signaling between the network and the terminal, and services with a constant rate and other data with relatively high real-time requirements. The dispatching service is alloca...
