Embodiment Construction

[0025] For the situation of the satellite station, if the one-step access link delay is too long and the one-step access cannot be performed, then the two-step access method can be used. The idea is: the BSC judges whether the link delay of the ABIS port exceeds the maximum tolerable delay of one-step access. If it exceeds, the access mode of the terminal accessing the satellite site is converted to two-step access.

[0026] First, when the BSC receives the channel request message from the terminal, it needs to determine that the site accessed by the terminal is a satellite site, and the access method for the terminal to access the satellite site is one-step access, and then perform timeout judgment.

[0027] The specific way for the BSC to convert the access mode of the terminal accessing the satellite site to the two-step access method is to reset the access mode identification bit of the satellite site accessed by the terminal to the two-step access mode.

[0028] Further, ...

Abstract

The invention discloses a method for processing too long link delay of a satellite site. The method comprises the steps that a BSC (Base Station Controller) judges whether ABIS interface link delay is beyond the maximum tolerant delay of one-step access, and if so, converts the access way of accessing a terminal to the satellite site into two-step access. The invention also discloses a device for processing too long link delay of the satellite site. The method and device for processing too long link delay of the satellite site solve the problem that a grouping service cannot be carried out normally due to the too long link delay of the satellite site.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for processing excessively long time delay of a satellite site link. Background technique [0002] In some isolated islands or base stations in ecological uninhabited areas, it is often impossible to configure the E1 transmission line (E1 transmission line), network cable or optical fiber required for transmission due to the limitation of the geographical environment or the limitation of human, material and financial resources. Satellite link transmission instead of cable transmission. The advantage of the satellite link is convenient networking and low cost, but the disadvantage is relatively obvious, that is, the transmission delay is long, which will adversely affect the packet service. [0003] In the existing Global System of Mobile communication (GSM, Global System of Mobile communication) technology, the standard perigee two-way time delay of the ABIS port...
