Description

Dynamically control the method and apparatus of the discontinuous reception of subscriber equipment

Technical field

(Discontinuous Receive, DRX) technology are meant the method and apparatus of the discontinuous reception of a kind of dynamic control subscriber equipment especially to the present invention relates to discontinuous reception.

Background technology

Along with developing rapidly of mobile communication technology, the disposal ability of portable terminal strengthens rapidly, and the function that provides increases rapidly.Future mobile communication system is when providing the higher availability of frequency spectrum, higher data rate, more colourful multimedia service, and the power problems at its terminal is also more severe.Especially; The access network of future mobile communication system all will carry out transfer of data based on the IP technology; And the burst characteristic of IP packet and the transmission channel sharing characteristic between the user makes that the data that arrive subscriber equipment are discontinuous; The energy consumption of therefore, how to save subscriber equipment seems more important.A lot of communication standardizations are organized in and have all added the consideration to power saving when formulating relevant criterion.

At present; Typical power-saving mechanism comprises 3 kinds of power-saving types (the Power Saving Class among the up-to-date WMAN standard 802.16e of IEEE in the GSM; PSC) and " discontinuous reception " (Discontinuous Receive, DRX) mechanism in the cellular network.

Stipulate in the IEEE 802.16e standard that (Mobile Station MS) has activation and two kinds of mode of operations of dormancy to each portable terminal.Under park mode, MS carries out the dormancy period that consults with base station BS, in these cycles; There is not data interaction between MS and the serving BS broadcasts; MS can close relevant physical equipment, reduces the MS power consumption and saves base station (Base Station, BS) purpose of air interface resource thereby reach.When MS was in resting state, BS can cushion the service data unit that sends to MS.When each enable mode finishes, carry out sleep messages between MS and the BS and consult with the initialization park mode.After the two confirmed sleep messages, normal transfer of data stopped at the time point of consulting, and enable mode finishes, and MS gets into park mode, with certain interval dormancy, woke up then and confirmed whether need receive data.This interim wake-up states is called listening intervals.In listening intervals, MS monitors the message of indicating about business in the BS broadcast message.If have data need mail to MS among this message indication BS, MS then gets into enable mode; Otherwise MS keeps park mode, begins next sleep interval.In park mode, each professional connection can be according to the related suitable power-saving type of own characteristic.The power-saving type is defined as one group of connection with same requirements.802.16e in have 3 kinds of power-saving types, each type has different parameter sets, suitable business and implementation.First type (type I) is applicable to and does one's best and non real-time variable Rate business.Second type (Type II) is applicable to unsolicited grant service and variable Rate is professional in real time.The third type (type-iii) is applicable to that multicast connects and the operation relevant with management.

(Global System for Mobile communications, GSM) in the system, travelling carriage is every just wakes up once at a distance from several " multiframes " (being about as much as 1/8th seconds time period), is in sleep state At All Other Times always in global system for mobile communications.System can indicate the travelling carriage per second to wake up and check whether incoming call is arranged for 4 times, or approximately per second wakes up to check whether incoming call is arranged for 1 time.In the DRX operation, processor will cut out receiver and make and oneself get into the sleep pattern of low-power consumption.Restarting processor by timer internal through after the suitable length of one's sleep.

The 3G Universal Mobile Telecommunications System (Universal Mobile Telecommunication System, under the DRX mechanism in UMTS), the subscriber equipment receiver has 3 kinds of active states:

1. active period: in active period, subscriber equipment is opened receiver and is received the packet that network side transmits.

2. deexcitation phase: when not having to mail to the data of subscriber equipment in the network side buffer, subscriber equipment is opened a deexcitation timer, gets into the deexcitation phase.If the corresponding data buffer of data arrives network side is arranged before timer expired, timer stops, and finishes the deexcitation phase, begins next active period; If there is not packet to arrive the corresponding data buffer of network side before the timer expired all the time, then finish the deexcitation phase, subscriber equipment cuts out receiver, begins to get into rest period.

3. rest period: subscriber equipment gets into the DRX pattern in rest period.Rest period comprises at least one DRX circulation.In the ending of each DRX circulation, subscriber equipment can be opened the receiver monitoring seek channel.Beep-page message is used in reference to and is shown in the data buffer whether previous DRX circulation has packet arrival network side correspondence.If have, then stop rest period, and subscriber equipment begins to receive packet from network side; If there is not packet to arrive the corresponding data buffer of network side, subscriber equipment then gets into next DRX circulation, continues rest period.

Active period and deexcitation phase belong to the power enable mode, and under this pattern, the subscriber equipment receiver is in open mode, and network side can send packet to subscriber equipment.Rest period belongs to power saving mode, and under this pattern, the subscriber equipment receiver is in closed condition, and network side does not send packet to subscriber equipment.

(Long Term Evaluation, LTE) in the system, network side is each user device configuration DRX loop parameter at Long Term Evolution.A DRX circulation was made up of active period and rest period.Active period comprises again to be opened duration and deexcitation phase.In this case, the subscriber equipment receiver has following 4 kinds of active states:

1. open the duration: subscriber equipment is waken up to get into from rest period and is opened the duration.Opening in the duration, subscriber equipment receives Physical Downlink Control Channel (Physical Downlink Control Channel, information PDCCH).Network side is arranged to notification of user equipment, relevant signaling information on the PDCCH channel, like the control messages about resource allocation such as affirmation, power control, resource allocation and reallocation with subscriber equipment.If subscriber equipment can successfully be decoded to the information of PDCCH signal, then open the deexcitation timer, get into the deexcitation phase; Otherwise subscriber equipment gets into rest period after opening the duration end.

2. deexcitation phase: after subscriber equipment was successfully decoded the PDCCH channel, subscriber equipment was opened the deexcitation timer, got into the deexcitation phase.In the deexcitation phase, subscriber equipment continues to monitor PDCCH and associated control channel.If subscriber equipment before the deexcitation timer expired, successfully to PDCCH and associated control channel decoding, is then opened the deexcitation timer again, get into the deexcitation phase once more; Otherwise subscriber equipment gets into rest period by the deexcitation phase behind the deexcitation timer expired.

3. active period: the time (comprise and opening duration and deexcitation phase) that the subscriber equipment receiver is in opening all belongs to active period.

4. rest period: the subscriber equipment receiver is in closed condition in rest period.

From above-mentioned introduction, can find out, at 802.16e, in the power-saving mechanism of GSM and UMTS system, in case the number of the packet in the service queue that network side is a subscriber equipment to be set up greater than zero, user terminal is promptly carried out continuous receiving course.Have only when the number of data packets in the said service queue equals zero, subscriber equipment just might be carried out discontinuous receiving course.And in the power-saving mechanism of LTE, even packet is arranged in the said service queue, subscriber equipment also can be carried out discontinuous receiving course.Therefore, than 802.16e, GSM and UMTS system, the user terminal in the LTE system has better energy saving.
