Embodiment Construction

[0032] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] like figure 1 Shown, according to the SSCOP link sliding window update method in the mobile communication system of the present invention comprises step S102, the link all calls CPCS / ATM detection function to obtain the current remaining number of CPCS / ATM cache when receiving a data packet every time. number.

[0034]Then, in step S104, according to the current remaining number and the remaining number of receiving buffers obtained in the previous period, an evaluation value of the current link receiving capability is calculated according to a predetermined algorithm. Wherein, the previous period refers to the interval period between two receiving windows....

Abstract

The present invention provides a kind of SSCOP link sliding window updating method, comprising: link all calls CPCS / ATM detection function to obtain the current remaining number of CPCS / ATM cache when receiving a data packet every time; According to the current remaining number Calculate the evaluation value of the receiving ability of the current link according to the predetermined algorithm and the remaining number of the receiving buffer obtained in the previous period; determine the size of the receiving window according to the predetermined rule according to the evaluation value and the total number of buffers. Therefore, the update of the SSCOP link sliding window between the core network CN, the radio network controller RNC and the base station NodeB of the third generation mobile communication system using ATM technology as the terrestrial transmission bearer is realized.

Description

technical field [0001] The present invention relates to a sliding window update method for SSCOP links, more specifically, relates to a core network CN, a radio network controller RNC and a base station NodeB of a third generation mobile communication system using ATM technology as a ground transmission bearer. A method for updating the sliding window of the SSCOP link between meta-devices. Background technique [0002] When the third-generation mobile communication system uses ATM (Asynchronous Transfer Mode) technology as the ground transmission bearer, the Iu interface between the core network CN (Core Network) and the radio network controller RNC (radio network controller) (between the RNC and the core network) interface), the Iub interface between the RNC and the base station NodeB (the base station) (the interface between the RNC and the base station) and the Iur interface between the RNCs (the logical interface between two RNCs, which may not be a point-to-point conne...
