Description
Technical field
The present invention relates to arrowband Internet of Things field, instruction, processing method and the dress stopped in particular to a kind of session
Put.
Background technology
In third generation partner program (3GPP) Long Term Evolution (LTE), single cell point is introduced to multicast communication
(SC-PTM), SC-PTM technologies are used for the downlink Multimedia for realizing that transmission is point-to-multipoint in single cell (a single cell)
Broadcast multi-broadcasting (MBMS) business.SC-PTM introduces two kinds of logic channels, i.e., single cell multicast control channel (SC-MCCH) and list
Cell multicast transmission channel (SC-MTCH).In LTE, SC-MCCH and SC-MTCH passes through Physical Downlink Shared Channel
(PDSCH) carried.
The related control information of SC-MCCH channel bearings transmission MBMS, it includes but is not limited to：The mark of business,
Schedule information.In LTE, the PDSCH for carrying SC-MCCH is dynamic dispatching.Specifically, in System information block 20 (SIB20)
The schedule information of SC-MCCH channels is indicated, it can include but is not limited to：Change the cycle, the repetition period, skew (offset),
First subframe (first subframe) and the siding-to-siding block length (duration) that may be scheduled.These parameters define
What the section for the duration that SC-MCCH may be scheduled, i.e. evolution base station (eNB) may be scheduled in SC-MCCH
SC-MCCH is dispatched in specific sub-frame in duration sections.
Fig. 1 is the scheduling mode schematic diagram of SC-MCCH channels in the LTE according to correlation technique.As shown in figure 1, SC-MCCH
The modification cycle be used to refer to the border that SC-MCCH message may be changed, the SC-MCCH repetition periods send SC- for scheduling
The cycle of MCCH message, offset refer to that duration startings radio frames originate the inclined of radio frames with respect to the SC-MCCH repetition periods
Radio frames number is moved, first subframe are which wireless sub-frame duration is originated in radio frames since it.
Duration length is the quantity of the lasting wireless sub-frames of duration.ENB uses single Cell Radio Network Temporary Identifier/Identity, Cell-RNTI
(SC-RNTI) Downlink Control Information (DCI) in Physical Downlink Control Channel (PDCCH) is scrambled.
One SC-MTCH carries MBMS business datum.In LTE, SC-MTCH schedule information can include but
It is not limited to：Dispatching cycle, start offset, the duration time interval length OnDurationTimer that may be scheduled and
The time span that user equipment (UE) waits after a downlink data is successfully received
(drxInactivityTimerSCPTM).Fig. 2 is the scheduling mode signal of SC-MTCH channels in the LTE according to correlation technique
Figure.As shown in Fig. 2 eNB equal schedulable carryings in any one wireless sub-frame in the resource that SC-MTCH schedule informations are specified
The SC-MTCH of specific MBMS PDSCH channels, UE continue after a downlink data of the business being successfully received
Above-mentioned drxInactivityTimerSCPTM time spans are waited, until the time is overtime or receives one of the business newly
Data.ENB is scrambled using group Radio Network Temporary Identifier (G-RNTI) to the DCI for dispatching SC-MTCH PDCCH, often
Individual MBMS is assigned single G-RNTI.
However, when introducing SC-PTM in arrowband Internet of Things (NB-IoT) or enhancing inter-machine communication (eMTC), there will be
The problem of following：
Fig. 3 is the process schematic that session stops in the LTE according to correlation technique.As shown in figure 3, in SC-PTM, just
The schedule information of MBMS in transmission is indicated to UE in SC-MCCH message, if a MBMS session stops
When, core net stops sending business datum (being sent) first, and then MBMS sessions are stopped (MBMS by core network element
Session stop) message is sent to access network elements, and access network elements are in next modification cycle, by the tune of corresponding service
Degree information removes from SC-MCCH message, and indicates that the content of SC-MCCH message is become by SC-MCCH Notifications of Changes
Change, or the beginning in each SC-MCCH modification cycles of the UE in business procedure is received actively receives SC-MCCH message.So, exist
When the schedule information of corresponding MBMS is removed in SC-MCCH message, UE can know that the business is over scheduling, because
And cease attempt to receive the scheduling of the SC-MTCH channels of the business.
But in NB-IoT or eMTC, in order to realize UE power savings, the modification cycle of its system message is most long up to 3
As long as hour.Correspondingly, the modification cycle of SC-MCCH channels may need to be consistent with the modification cycle of system message or
The purpose for reaching UE power savings is similarly, it is necessary to which SC-MCCH modification Cycle Length is configured into longer time.So, this anticipates
Taste a business when stopping, and UE needs one section of longer time to obtain the business from the change of SC-MCCH message
The instruction of stopping.And before this, even if core net stopped transmission business datum, UE is still each SC-MTCH's
Reception SC-MTCH scheduling is attempted in dispatching cycle.In view of SC-MCCH modification the cycle it is most long may be up to 3 hours, herein
During, the trial reception SC-MTCH scheduling meetings that UE is not necessarily to cause the substantial amounts of battery consumptions of UE.
For it is above-mentioned the problem of, not yet propose effective solution at present.
