Embodiment 1

[0067] Step 101: The mode of determining the adjustment rate is event-triggered adjustment.

[0068] Step 102: The condition for determining the adjustment rate is the number of users in the network.

[0069] Step 103: Determine the AMBR rate change mode as adjusting the relative value.

[0070] Step 104: At time T1, the base station counts that the number of users in the network exceeds the user number threshold 1, and starts AMBR rate adjustment for the users.

[0071] Step 105: Obtain the priority of bearers in the network. The current bearer priority is divided into 2 levels, wherein the first level has 10 bearers, and the second level has 100 bearers.

[0072] Step 106: Adjust the AMBR rate of users corresponding to the 10 bearers in the first class of service bearer priority, and reduce the AMBR rate by 20% for each user.

[0073] Step 107: the base station schedules the users next time according to the latest adjusted AMBR rate.

[0074] Step 108: At time T2, the bas...

Embodiment 2

[0081] Step 201: The mode of determining the adjustment rate is periodic trigger adjustment.

[0082] Step 202: The condition for determining the adjustment rate is resource utilization.

[0083] Step 203: Determine the AMBR rate change mode and adjust the absolute value.

[0084] Step 204: At the beginning of the first cycle, the base station counts that the resource utilization rate in the network exceeds the resource utilization rate threshold 1, and starts AMBR rate adjustment for the user.

[0085] Step 205: Obtain the priority of bearers in the network. The current bearer priority is divided into 2 levels, wherein the first level has 10 bearers, and the second level has 100 bearers.

[0086] Step 206: Adjust the AMBR rate of users corresponding to the 10 bearers in the first class of service bearer priority, and reduce the AMBR rate of each user by 1 Mbps.

[0087] Step 207: the base station schedules the users next time according to the latest adjusted AMBR rate.

Embodiment 3

[0095] Step 301: The mode of determining the adjustment rate is event-triggered adjustment.

[0096]Step 302: The condition for determining the adjustment rate is the number of service bearers.

[0097] Step 303: Determine the AMBR rate change mode and adjust the relative value.

[0098] Step 304: At time T1, the base station counts the number of service bearers in the network as exceeding the service bearer number threshold 1, and starts AMBR rate adjustment for the user.

[0099] Step 305: Obtain the priority of bearers in the network. The current bearer priority is divided into 2 levels, wherein the first level has 20 bearers, and the second level has 100 bearers.

[0100] Step 306: Adjust the AMBR rate of the users corresponding to the 20 bearers in the first class of service bearer priority, and reduce the AMBR rate of each user by 20%.

[0101] Step 307: the base station schedules the users next time according to the latest adjusted AMBR rate.

[0102] Step 308: At T2...

Abstract

The invention discloses a method and device for self-adaptive adjustment of user AMBR rate, and relates to the technical field of wireless communication. According to the adjustment method and the collected network-related data, it is judged whether it is necessary to start the AMBR rate adjustment of the user; AMBR rate is adjusted. The present invention satisfies the scheduling requirements of different users, and maximizes the user's network experience and service experience.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for self-adaptive adjustment of AMBR (Aggregate Maximum BitRate, total maximum bit rate) rate of a user. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution technology) system, AMBR is used to limit the upper limit of the aggregation rate of all Non-GBR (Non-Guaranteed Bit Rate, non-guaranteed code rate) bearers of a UE. This parameter is stored in the HSS (Home In the Subscriber Server (home subscription server), AMBR rate data exceeding UE (User Equipment, user equipment) may be discarded by the rate shaping function. After the user establishes a link with the LTE network, a default bearer will be established first. This bearer is a Non-GBR bearer. In addition to the default bearer, the user can also negotiate with the core network to establish a dedicated bearer. The dedicated bearer can be a GBR bearer ...
