A method and device for realizing one-step access

Abstract

The invention discloses a method and device for realizing one-step access, including: calculating the two-way time delay of the link, judging whether the two-way time delay of the link is greater than the maximum time interval allowed by the protocol; When the delay is greater than the maximum time interval allowed by the protocol, determine the transmission block interval of the downlink block sent to the user equipment to set the user equipment's uplink status flag (USF), wherein the transmission block interval is greater than the two-way link of the link Delay / the maximum time interval allowed by the protocol, sending the downlink block for setting the USF of the user equipment to the user equipment at a certain sending block interval. The present invention adjusts the sending interval of the USF when the two-way delay of the link exceeds the standard of the limited delay, so as to ensure that the uplink can be allocated in time according to the actual situation, and the user equipment will not be forcibly released due to the restriction of one-step access, thereby solving the problem of The problem of inaccessibility caused by the long delay of the link is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for realizing one-step access. Background technique [0002] In GSM (Global System for Mobile Communications), there may be many situations in the networking of the Abis port. Among them, a satellite link may be used. The standard two-way delay of the usual high-orbit satellite link is 520ms, plus the landing link router, The processing time of the digital circuit signal multiplication system and the delay of the air interface, etc., the maximum delay may exceed 1100ms or more. At the same time, in the actual network environment, there are still cases where the BTS (base transceiver station) passes through the satellite to the transit router and then passes through the satellite to the BSC (base station controller). It may need to go through multiple satellite links in the middle, so that the entire Abis link The time delay will be greatly incr...

Problems solved by technology

[0004] BS_CV_MAX is the system configuration, and the maximum value of BS_CV_MAX is 15. For most user equipment, under one-step access, BSC generally allocates an uplink channel, and the maximum value of N3104_MAX is 54 blocks. At the same time, BSC receives the first wireless block, reply the packet uplink response, when the two-way delay is 54 blocks, 54 blocks are equivalent to 1080ms, that is, when the user equipment sends the 27th block, the BSC receives the first block, and starts to send the packet uplink response, the packet uplink The response arrives at the user equipment after a one-way link delay of 27 blocks, and the user equipment sends 27+27=54 blocks, which reaches N3104_MAX. If the two-way delay is greater, the one-step conflict resolution failure will cause the service to be unable to access
