Description
Technical field
The present invention relates to wireless communication field; Relate in particular to multimedia broadcast multi-broadcasting business (the enhanced Multimedia Broadcast Multicast Service of enhancing; EMBMS) in the system a kind of point to descending multicast control channel (the Multicast Control Channel of multiple spot; MCCH) Notification of Changes sending method, and corresponding Notification of Changes method of reseptance and device.
Background technology
MCCH is that a kind of point is to the down channel of multiple spot in the eMBMS system, and (this channel is only useful to receiving the professional user terminal of eMBMS for User Equipment, control information UE) to user terminal to be used to transmit network side.
The information of the last transmission of MCCH comprises:
The eMBMS business information: obtainable eMBMS is professional in this information indicating cell.For every kind of business, possibly comprise service identification (traffic ID), session identification (session id), radio bearer discharges information such as indication;
The radio bearer relevant information: the radio bearer that uses in the sub-district that this information is served for one or more eMBMS business descriptions with put the multiple spot beared information.For every kind of business, possibly comprise traffic ID, physic channel information, transmitting channel information, radio bearer information etc.; And
Out of Memory.
Network side BCCH (Broadcast Control Channel, BCCH) in the positional information of indication MCCH, go up the information that transmits thereby make user terminal can position as indicated read MCCH.
The MCCH definition has modification cycle (Modification period) and repetition period (Repetition period).The content that MCCH transmits is to repeat in the cycle to send with Repetition period, and in a Modification period, can not change.That is: when the information of carrying as MCCH is sent and changed, can only, could send next Modification period the information after changing after beginning.And Modification period is the integral multiple of Repetition period.
When the information of carrying as MCCH changes, change like the business of eMBMS, when session or radio bearer information etc. changed, network side needed informing user terminal; Be that network side need send the MCCH Notification of Changes to user terminal; User terminal can remove to intercept MCCH and obtain the fresh information after changing after receiving the MCCH Notification of Changes.
In the prior art, the method for sending the MCCH Notification of Changes to user terminal has following two kinds:
Method one, in sending to the paging of user terminal (paging) packets of information, carry the MCCH Notification of Changes.
In the prior art; Receive professional user terminal of eMBMS and the user terminal that receives only unicast service, all will receive (Discontinuous Reception, DRX according to the distinctive noncontinuity of paging;) cycle, promptly actual paging cycle is waken up and is come to intercept paging information.If carried the MCCH Notification of Changes in the paging packets of information, then user terminal can remove to intercept MCCH and obtain change fresh information afterwards.
In the said method one, when the information of carrying as MCCH changes, carry the MCCH Notification of Changes in the paging packets of information that network side can send at each follow-up actual paging cycle.For example: the Modification period that supposes MCCH is 10240 milliseconds (ms), and actual paging cycle is 320 milliseconds, and then a corresponding period of Modification period has comprised 32 actual paging cycle; When the information change that MCCH carries, network side all carries the MCCH Notification of Changes at most in 32 paging packets of information that 32 follow-up actual paging cycle send.Because the MCCH Notification of Changes sends (network side is not distinguished and received professional user terminal of eMBMS and the user terminal that receives only unicast service) to all user terminals in the eMBMS system; Therefore; Receive only the user terminal of unicast service; Also will resolve one by one these 32 paging packets of information; And the result who resolves, possibly be: these 32 paging packets of information are not (or wherein major part is not) real paging bags, and only are because the corresponding paging packets of information that MCCH change network side sends; And,, resolve the paging packets of information that only is used to carry the MCCH Notification of Changes because it need not obtain the MCCH relevant information for the user terminal that receives only unicast service, only can bring additional electric energy consumption.Particularly hour (value of actual paging cycle can be 320ms in the prior art when the value of actual paging cycle; 640ms; 1280ms and 2560ms); For the user terminal that receives only unicast service, need resolve more only being used to continually and notify MCCH the corresponding paging packets of information of change.Therefore, method influences the performance of the user terminal that receives only unicast service for a moment.
Method two, (Physics Down Control Channel PDCCH) carries the MCCH Notification of Changes through Physical Downlink Control Channel.
In method two; When the information of carrying as MCCH changes; Network side can be in each follow-up actual paging cycle, through PDCCH send a multi-media radio network temporary identifier (Multimedia-Radio Network Temporary Identifier, M-RNTI).The professional user terminal of reception eMBMS is waken up according to actual paging cycle and is come to intercept the M-RNTI on the PDCCH.If detect and carried M-RNTI on the PDCCH, represent that then change has taken place the information on the MCCH, user terminal can further be intercepted MCCH and obtained new information.In this method two, the professional user terminal of reception eMBMS need be waken up continually according to actual paging cycle and come to intercept the M-RNTI on the PDCCH, needs to consume more electric energy.
In the reality, for user terminal, obtaining the time delay that the MCCH Notification of Changes can tolerate can be a second level, and therefore, it is identical with actual paging cycle that the Notification of Changes of MCCH there is no need.

Embodiment
The embodiment of the invention provides MCCH Notification of Changes sending method, MCCH Notification of Changes method of reseptance and relevant base station and user terminal, when realization sends to user terminal with the MCCH Notification of Changes, effectively reduces the power consumption of user terminal.
Below in conjunction with accompanying drawing, the method step that the embodiment of the invention is provided and the concrete structure of relevant base station and user terminal are elaborated.
Implement 1: a kind of MCCH Notification of Changes sending method is provided.
Referring to Fig. 1, the MCCH Notification of Changes sending method flow chart of steps that provides for the embodiment of the invention 1.Comprise:
Step S101, base station are through BCCH, and the announcement period of MCCH Notification of Changes is sent in broadcasting.The corresponding duration of this announcement period is N a times of the public paging cycle in sub-district; N is the positive integer more than or equal to 1.
Step S102, when the information of carrying as MCCH changes, the base station is sent the MCCH Notification of Changes and is given user terminal according to the announcement period that sends the MCCH Notification of Changes.
The corresponding duration of the announcement period among the above-mentioned steps S101 is N a times of the public paging cycle in sub-district; The concrete value of N is obtained the maximum delay of MCCH Notification of Changes by the base station according to user terminal, and the concrete value of the public paging cycle in sub-district of the current employing of network is confirmed.Illustrate as follows:
The value of supposing the public paging cycle in sub-district of the current employing of network is 320ms, and the maximum delay that user terminal obtains the MCCH Notification of Changes is 1000ms; In theory, the value of N is 1,2 or 3 o'clock, and the announcement period that sends the MCCH Notification of Changes is respectively the requirement that 320ms, 640ms and 960ms can both satisfy maximum delay 1000ms; On the basis of satisfying the maximum delay requirement; Obtain the electric energy that the MCCH Notification of Changes is consumed in order to reduce user terminal as much as possible; Should adopt long announcement period, in the preferred embodiment, choose the maximum in the various possible N value that satisfies the maximum delay requirement; In this example, get N=3;
And for example: the value of supposing the public paging cycle in sub-district of the current employing of network is 640ms; The maximum delay that user terminal obtains the MCCH Notification of Changes is 3000ms; In theory; The value of N is 1,2,3 or 4, and the announcement period that sends the MCCH Notification of Changes is respectively the requirement that 640ms, 1280ms, 1920ms and 2560ms can both satisfy maximum delay 3000ms; On the basis of satisfying the maximum delay requirement; Obtain the electric energy that the MCCH Notification of Changes is consumed in order to reduce user terminal as much as possible; Should adopt long announcement period, in the preferred embodiment, choose the maximum in the various possible N value that satisfies the maximum delay requirement; In this example, get N=4;
For another example: the value of supposing the public paging cycle in sub-district of the current employing of network is 2560ms, and the maximum delay that user terminal obtains the MCCH Notification of Changes is 3000ms, and in order to satisfy the maximum delay requirement, the value of N can only be N=1.
After having confirmed that sending the MCCH Notification of Changes is the N public paging cycle in sub-district doubly, in step S101, the base station is on BCCH, and the periodic broadcasting network side sends the announcement period of MCCH Notification of Changes.The concrete mode of notice includes but not limited to:
The base station on BCCH, the N that determines of broadcasting multiple value doubly, for example 8.Perhaps, the base station is on BCCH, and the interval duration of MCCH Notification of Changes, for example 1280ms are sent in broadcasting.
User terminal can know that through intercepting BCCH network side sends the announcement period of MCCH Notification of Changes.
When the information of carrying as MCCH will change, the base station needed timely informing user terminal.Network side sends the starting point of MCCH Notification of Changes for the first time to user terminal, following implementation can be arranged:
Mode one: MCCH Notification of Changes is for the first time sent to user terminal in the base station in follow-up first actual paging cycle.
Mode two: the base station is according to current System Frame Number (System Frame Number; SFN), the side-play amount of actual paging cycle and the announcement period determined; Determine in the radio frames of sending the MCCH Notification of Changes and the immediate follow-up corresponding System Frame Number of current System Frame Number, the paging subframe from the radio frames of this correspondence System Frame Number begins to send MCCH Notification of Changes for the first time.Specify as follows:
The span of SFN is 0-1023, and the length in a SFN cycle is 1024*10ms=10240ms (1 radio frames is 10ms), i.e. 10.24S.Suppose:
The public paging cycle of current area is 640ms, i.e. 64 radio frames, and the announcement period that network side is determined is 1280ms or 128 radio frames, so corresponding multiple value N=2.Network side is broadcast to user terminal to 1280ms or radio frames number 128 or multiple value 2 through BCCH.Because network side and user terminal are all known the side-play amount of actual paging cycle synchronously; Suppose that side-play amount is 4 wireless sub-frames, the corresponding SFN of radio frames that sends the MCCH Notification of Changes so satisfies: SFN mod 128=4, and promptly SFN is 4 in theory; 132; 260 ...., 900 corresponding radio frames can be sent the MCCH Notification of Changes; For with MCCH change as early as possible notice give user terminal, choose and be not less than current System Frame Number, and send the MCCH Notification of Changes with the paging subframe in the immediate follow-up corresponding system-frame of current System Frame Number.
According to the MCCH Notification of Changes sending method that the above embodiment of the present invention 1 provides, the information of carrying as MCCH will change, and the corresponding MCCH Notification of Changes that network side sends to this time information change possibly be repeatedly (also maybe only once).In concrete the application, the base station generally after the information that MCCH carries has changed, stops to send the MCCH Notification of Changes.When information that MCCH carries changed in follow-up some MCCH modification cycles once more, the base station starts once more sent the MCCH Notification of Changes.For example: the Modification period that supposes MCCH is 10240ms; The public paging cycle in the sub-district of the current employing of network is 320ms; Announcement period is the public paging cycle in 8 times sub-district; Be that announcement period is 2560ms, then the base station in the period before the information that MCCH carries changes the interval duration according to 8 the public paging cycle in sub-district in every interval send the MCCH Notification of Changes.
The MCCH Notification of Changes sending method that the above embodiment of the present invention 1 provides, the concrete implementation of sending the MCCH Notification of Changes can adopt advice method of the prior art, comprising:
In the paging packets of information, carry the MCCH Notification of Changes and send to user terminal; Perhaps in PDCCH, carry the MCCH Notification of Changes and send to user terminal.
In concrete the realization, the present invention is not limited to adopt above-mentioned two kinds of advice methods of the prior art.For example, also can in other common downlink channel, send the MCCH Notification of Changes and give user terminal.
Embodiment 2: a kind of MCCH Notification of Changes method of reseptance is provided.
Based on same inventive concept, according to the MCCH Notification of Changes sending method that the above embodiment of the present invention 1 provides, the embodiment of the invention 2 provides a kind of corresponding M CCH Notification of Changes method of reseptance.
Referring to Fig. 2, the MCCH Notification of Changes method of reseptance flow chart of steps for the embodiment of the invention 2 provides comprises:
Step S201, user terminal obtain the announcement period that network side sends the MCCH Notification of Changes from BCCH.This announcement period is N a times of the public paging cycle in sub-district; N is the positive integer more than or equal to 1.
Step S202, when user terminal receives the MCCH Notification of Changes in current actual paging cycle, begin from current actual paging cycle, in the corresponding actual paging cycle of the said announcement period in every interval, start to receive the MCCH Notification of Changes.
According to the MCCH Notification of Changes sending method that the above embodiment of the present invention 1 provides, the base station confirms that the announcement period of transmission MCCH Notification of Changes is the N public paging cycle in sub-district doubly, and gives user terminal through this announcement period of BCCH periodic broadcasting.And the base station is according to the announcement period of determining when sending the MCCH Notification of Changes, and the corresponding duration of the public paging cycle in every interval N sub-district sends a MCCH Notification of Changes.Therefore; In embodiment 2, user terminal is through intercepting BCCH, and (that network side possibly send is multiple value N can to obtain the announcement period that network side sends the MCCH Notification of Changes; What also possibly send is the corresponding duration at interval of announcement period); If that network side sends is multiple value N, then user terminal multiply by the public paging cycle in sub-district with this multiple value N, can obtain the corresponding duration at interval of announcement period.When network side send be concrete interval duration the time, user terminal adopts the interval duration that the receives corresponding duration divided by actual paging cycle, just can determine to receive the actual paging cycle quantity X that the MCCH Notification of Changes can the interval.When user terminal receives the MCCH Notification of Changes in current actual paging cycle, only need in the corresponding actual paging cycle behind every interval X the actual paging cycle, start reception MCCH Notification of Changes once more and get final product.Continue to use example; The Modification period that supposes MCCH is 10240ms; The public paging cycle in the sub-district of the current employing of network is 320ms; Announcement period is the public paging cycle in 8 times sub-district; Suppose that actual paging cycle is 320ms (identical with the public paging cycle in sub-district), and user terminal received the MCCH Notification of Changes in previous Modification period the 1st the actual paging cycle in the corresponding period that the MCCH information of carrying changes, then user terminal begins from the 1st actual paging cycle of the current MCCH of receiving Notification of Changes; In the corresponding actual paging cycle behind 8 actual paging cycle in every interval (essence equals 8 public paging cycle in sub-district), promptly start reception MCCH Notification of Changes in the the 9th, the 17th and the 25th actual paging cycle.
When the public paging cycle of actual paging cycle and sub-district does not wait, for example: the public paging cycle in sub-district is 640ms, and actual paging cycle is 320ms; When announcement period was 8 times sub-district public paging cycle, announcement period corresponding intervals duration was: 640*8=5120ms.Then user terminal receives the MCCH Notification of Changes needs actual paging cycle quantity at interval to be: 5120/320=16.Be 16 the actual paging cycle in the every interval of user terminal, start reception MCCH Notification of Changes.
In the practical application, after user terminal has received a MCCH Notification of Changes, will remove to intercept MCCH, obtain the fresh information after the variation.Because in the Modification period of MCCH, the information of the last transmission of MCCH can not change; Although network side possibly send repeatedly MCCH Notification of Changes according to the method for the above embodiment of the present invention 1 in the Modification period of MCCH; But, MCCH only changed once because going up the information essence that transmits; Therefore, user terminal can no longer receive the MCCH Notification of Changes that network side sends once more in this Modification period.Given this; User terminal is before starting reception MCCH Notification of Changes; Can judge earlier that this starts the corresponding actual paging cycle that receives the MCCH Notification of Changes; Whether belong in the same Modification period with the corresponding actual paging cycle that started reception MCCH Notification of Changes last time, if then abandon this and start reception MCCH Notification of Changes.
When the MCCH Notification of Changes was carried through the paging packets of information in the base station, user terminal correspondingly through resolving the paging packets of information, received the MCCH Notification of Changes that wherein carries;
When the MCCH Notification of Changes was carried through PDCCH in the base station, user terminal correspondingly through intercepting PDCCH, received the MCCH Notification of Changes that wherein carries.
