Problems solved by technology

[0020] Due to user mobility characteristics, user service characteristics or network resource load, etc., RRM needs to comprehensively consider multiple factors in order to make a more appropriate choice between each RRC connection state of UMTS and LTE RRC connection state, otherwise it will not only be for the two The system brings unnecessary signaling overhead and wireless resource consumption, and will also produce some unavoidable business interruptions, user service experience degradation and other adverse consequences

Embodiment 1

[0071] as attached Figure 4 As shown, the serving RNC sends the parameter in the decision inequality through the system broadcast message: factor dch-＞fach = 0.3, offset = 1kbps, T DCH-＞FACH = 60s.

[0072] UE A is in Cell_DCH state first, and records rate 1=30kbps, rate 2=25kbps before migrating to FACH state;

[0073] UE A records rate 3=18kbps and rate 4=24kbps after migrating to FACH state;

[0074] UE A determines the inequalities Rate 2>Rate 1+offset and Rate 4>=Rate 3>factor dch-＞fach *Whether one of (Rate 1+Rate 2)+offset is established, because Rate 4>=Rate 3>factor dch-＞fach *(Rate 1+Rate 2)+offset is established, so UE A detects and records the first DCH->FACH state inappropriate migration event;

[0075] UE A starts a timer T DCH-＞FACH = 0s, start timing, after that, at 20s, UE A transitions back to the Cell_DCH state due to the voice session. DCH-＞FACH Before the timeout of 60s, UE A detects the second DCH->FACH state inappropriate migration event, then UE...

Embodiment 2

[0077] as attached Figure 5 Shown: The serving RNC stipulates the parameter in the decision inequality through the 3GPP agreement: factor dch-＞lte =0.9, offset=-5kbps, T DCH-＞LTE = 120s.

[0078] UE B is in the Cell_DCH state first, and records rate1=20kbps and rate 2=15kbps before migrating to the LTE serving cell;

[0079] After migrating to the LTE serving cell, record rate 3 = 15kbps, rate 4 = 18kbps;

[0080] UE B determines whether one of the inequalities Rate 2lte*(Rate 1+Rate 2)+offset is true. Since none of the inequalities is true, UE B considers this Secondary DCH->LTE DRX state is a suitable transition event.

Embodiment 3

[0082] as attached Image 6 Shown: The serving RNC sends the parameter in the judgment inequality through the downlink proprietary message: factor fach-＞dch =1.1, offset=-2kbps, T FACH-＞DCH = 60s.

[0083] UE C is in Cell_FACH state first, and records rate 3=20kbps, rate 4=15kbps before migrating to DCH state;

[0084] After migrating to the DCH state, record to rate 1=16kbps, rate 2=18kbps;

[0085] UE C determines whether one of the inequalities Rate 4dch*(Rate 3+Rate 4)+offset is established. Since Rate 4DCH state inappropriate transition event;

[0086] And, UE C starts a timer T FACH-＞DCH = 0s, start timing, after that, at 30s, UE C migrates back to the Cell_FACH state due to the decrease of service data rate. FACH-＞DCH Before the timeout of 60s, UE C detects the second FACH->DCH state inappropriate migration event, then UE C records the event signaling overhead FACH-＞DCH .

[0087] like Figure 7 As shown, this embodiment also provides an apparatus for determining ...

Abstract

The present invention discloses a method and device for determining whether terminal state transition is appropriate, comprising: recording the average data rate of the terminal in the first state when the terminal is in the first state; , record the average data rate of the terminal in the second state, according to the change of the average data rate of the terminal in the first state, the change of the average data rate of the terminal in the second state is relative to the average data rate of the terminal in the second state Based on the change of the average data rate of the terminal in the first state, it is determined whether the terminal state transition is appropriate. The present invention provides a basis for the UE to select a more suitable RRC (sub) state and different DRX cycle lengths, so that the performance of the network in terms of overall wireless resource utilization efficiency, unnecessary signaling overhead, UE power protection, user service experience maintenance, etc. can be integrated Sexual improvement and optimization.

Description

technical field [0001] The present invention relates to a mobile communication system, in particular to a method and device for determining whether terminal state transition is appropriate. Background technique [0002] With the continuous increase in the number of contracted users and user business volume of telecom mobile operators, the investment and scale of their mobile network infrastructure are also expanding, and the width and thickness of wireless coverage are increasing. Taking most mobile operators in Europe as an example, they have successively deployed three mobile network systems based on different RATs (Radio Access Technology), namely: GSM (evolved to GERAN), UMTS (evolved to HSPA+ ) and LTE (the evolved version is LTE+). These mobile network systems are basically composed of three parts: terminal (the device used by users to communicate with the mobile network, which can be handheld, vehicle-mounted or fixed), wireless access network (network element equipm...
