Problems solved by technology

In the existing design, only ACK / NACK messages are sent from the base station actively. This method is issued in a fixed way when the base station cannot predict the terminal data. It has no adjustability and will occupy precious downlink resources in most cases. , resulting in a waste of resources

Embodiment Construction

[0021] This patent provides an efficient active polling mechanism under the GMR-1 3G protocol, which can ensure real-time advancement of uplink and downlink data interaction speeds.

[0022] The polling mechanism mainly uses the header parameter SI (stall indicator, stall indicator) to set an instruction to request the base station to send an ACK / NACK (confirmation / non-confirmation) message, that is, to set the active polling flag, and the terminal performs SI during the process of sending data blocks. Parameter setting: When the parameter is set to 1, it means that the base station is requested to send an ACK / NACK message; when the parameter is set to 0, it means no request.

[0023] The setting of the active polling flag does not affect the sending order of various types of data (refer to GMR-13G44.060 9.1.3.1 for details), and the various types of data include retransmitted data blocks, new data blocks, and data waiting for confirmation block, dummy data block.

Abstract

The invention discloses an efficient and active polling method for a terminal. When the terminal service uses the AM mode, an active polling flag is set for a data block, and the terminal uses an active polling mechanism to send the data block. During the process of sending the data block, the terminal performs real-time statistics The number M of upper-layer SDU data that has not been confirmed by the base station, when M is greater than the preset threshold C, set the active polling flag to 1, indicating that the base station is requested to send an ACK / NACK message, otherwise, set the active polling flag to 0, means no request. This method can ensure real-time advancement of the uplink and downlink data interaction speed, and is not only applicable to the RLC ACK / NACK interaction process specified in the GMR-1 3G protocol, but also applicable to polling mechanisms specified in other communication protocol standards.

Description

technical field [0001] The invention belongs to the technical field of broadband wireless communication protocol stacks, and in particular relates to a terminal efficient active polling method. Background technique [0002] The full name of GMR is GEO-Mobile Radio interface. The GMR standard was originally developed based on the ground GSM standard GEO satellite mobile communication system air interface technical specification, which is divided into GMR-1 and GMR-2. Among them, the GMR-1 standard is applied to the Thuraya system in the Middle East. , the GMR-2 standard is applied to the ACeS system. With the evolution of the terrestrial cellular system from GSM to GPRS and then to the 3G standard, the GMR-1 standard has also evolved, and the corresponding GMR-1Release1, GMR-1Release2 (ie GMPRS) and GMR-1Release 3 (ie GMR-1 3G). Among them, Release1 is based on the GSM standard and supports basic circuit domain voice and fax services. The interface between the satellite wir...
