Problems solved by technology

from figure 1 It can be seen from the figure that different BSSNs may establish connections with multiple BSs at the same time. Due to the different data volumes carried by different interfaces, it will inevitably lead to different quality of service (QS), which makes the network load unbalanced and reduces the efficiency of network operation.

Embodiment 1

[0063] like figure 2 Shown is the schematic diagram of the network of Embodiment 1 and Embodiment 2 of the present invention, in which figure 2 In this case, the BS is connected to the BSSN through the R6 interface, and the BSSN is connected to the CN through the R3 interface. If the resource usage and load of the BSSN reach the set threshold, the solution of the present invention will switch the R6 interface, which specifically includes the following contents.

[0064] like image 3 Shown, is the schematic flow chart of embodiment 1 of the present invention, from image 3 It can be seen that the present invention mainly comprises the following steps:

[0065] S11. The BSSN periodically broadcasts its network performance information to the BS.

[0066] Here it can be broadcast through the backbone network message BSSN Resource ADV. The message carries resource and load information of the network, and may include the following information: remaining processor resources (...

Embodiment 2

[0106] The difference between this embodiment and Embodiment 1 is that the handover of the R6 interface is initiated by the BSSN, such as Figure 8 Shown is the schematic flow sheet of embodiment 2, from Figure 8 As can be seen, the scheme may include the following.

[0107] S21. The BSSN periodically broadcasts its resource and load conditions to the BS.

[0108] Here it can be broadcast through the backbone network message BSSN Resource ADV. The message carries the following information: remaining processor resources (resource occupancy rate), memory remaining resources (resource occupancy rate), ingress port remaining traffic, and egress port remaining traffic.

[0109] S22. The BSSN detects its network delay information.

[0110] In this embodiment, the BSSN detects the content of its network performance parameters, which may be the network delay information of the BSSN.

[0111] Different from Embodiment 1, here, the BSSN periodically detects the network delay inform...

Embodiment 3

[0122] During the network air interface switching process, there will be such Figure 9 In the state shown, in this state, the BS does not directly communicate with the serving BSSN, but forwards data through another serving BS, and transmits the context data to the serving BSSN through the serving BS. In this way, if the current BS switches over the R6 interface, There is a case where the switched R6 interface is directly connected to the service BSSN, but for the R3 interface, there is no need to perform related switching, because after the R6 interface is switched, it still exchanges data with the core network through the original R3 interface. like Figure 7 As shown, it is a schematic flow chart of Embodiment 3, the handover process is initiated by the BS, from Figure 7 It can be seen that this embodiment mainly includes the following steps:

[0123] S31. The BSSN periodically broadcasts its resource and load conditions to the BS.

[0124] S32. The BS detects its load...

Abstract

A network optimizing method which based on announcement type wireless access network, the base station (BS) accesses the base station service node (BSSN) by the first R6 interface, the BSSN access the central network (CN) by the first R3 interface, it includes the following steps: A) the base station detects the capability parameter of the network, estimates the network capability parameter whether or not exceed the fixed threshold value, enter the step B if it is, repeat the step A if it is not; B) the base station choose the aiming base station service node, set the second R6 interface with the aiming base station service node, processes the communication by the second R6 interface; C) the aiming base station service node sets the second R3 interface with the central network, and processes the communication by the second R3 interface.

Description

technical field [0001] The invention relates to the communication field, in particular to a network optimization method based on a distributed wireless access network. technical background [0002] In the standard IEEE 802.16, a wireless metropolitan area network standard for fixed broadband wireless access (BWA) is defined. The standard defines different physical layer technologies for different frequency bands. The scope of application of the standard is mainly for the residential, small office / home office (SOHO), teleworker and small enterprise users (SME) markets. IEEE 802.16 MAC supports a very unfavorable user environment, can cope with the application environment that may have hundreds or thousands of users on each channel, and supports different business volumes such as continuous and burst. It has an ATM convergence sublayer and a packet convergence sublayer. After being processed by the convergence sublayer, multiple high-level data units are encapsulated into a ...
