Description
Technical field
The present invention relates to communication field, relate in particular to a kind of sending, receiving method and device of MCCH Notification of Changes.
Background technology
MCCH (Multicast Control Channel, multicast control channel) be eMBMS (EvolvedMultimedia Broadcast and Multicast Service, evolution type multimedia broadcast and multicast service) a kind of point-to-multipoint down channel in system, be used for transmitting network side to UE (User Equipment, user terminal) control information, this control information mainly comprises eMBMS business information and radio bearer relevant information.Wherein, eMBMS business information is used to indicate obtainable eMBMS business in community, user terminal place, for every kind of eMBMS business, in eMBMS business information, can comprise that traffic ID (service identification), session id (session identification) and radio bearer discharge the information such as instruction; The radio bearer and the point-to-multipoint beared information that in the community that radio bearer relevant information is served for one or more eMBMS business descriptions, use, for every kind of eMBMS business, radio bearer relevant information can comprise traffic ID, physic channel information, transmitting channel information and radio bearer information etc.
Network side is at BCCH (Broadcast Control Channel, Broadcast Control Channel) middle positional information of indicating MCCH, thereby make user terminal to read the upper information transmitting of MCCH in position as indicated, obtain corresponding business according to the control information of carrying in MCCH.
MCCH definition has Modification period (amendment cycle) and Repetition period (repetition period).Modification period is the integral multiple of Repetition period, in each Modificationperiod, the content that MCCH transmits repeats to send with Repetition period, and can not change in a Modification period, that is to say: when the information of carrying as MCCH changes, can only after next Modification period starts, just can send the information after variation.The content transmitting due to MCCH in same Modification period repeats to send with Repetition period, therefore, in same Modification period, UE is reading after the information transmitting on MCCH, can no longer continue to intercept the information on MCCH.
When the information of carrying as MCCH changes, for example: the business of eMBMS changes or radio bearer information etc. changes, network side needs informing user terminal to obtain in time the fresh information after changing of carrying on MCCH, be that network side need to send MCCH Notification of Changes to user terminal, user terminal, after receiving MCCH Notification of Changes, can remove to intercept MCCH and obtain the fresh information after changing.
In prior art, network side sends MCCH Notification of Changes by following two kinds of methods to user terminal:
In prior art one: carry MCCH Notification of Changes sending in the paging of user terminal (paging) packets of information.
Concrete, in prior art, the user terminal in eMBMS system comprises the user terminal that receives eMBMS business and the user terminal that receives only unicast service, these two kinds of user terminals are all intercepted paging information according to each user's oneself paging cycle.In the time having there is change in MCCH, network side sends a beep-page message that comprises the instruction of MCCH Notification of Changes to user terminal, corresponding PDCCH (PhysicalDownlink Control Channel, Physical Downlink Control Channel) on can send and the corresponding P-RNTI of this beep-page message, user detects after P-RNTI, will paging receiving message, know MCCH Notification of Changes, read the information of carrying on the MCCH after changing according to this MCCH Notification of Changes.
In prior art two: carry MCCH Notification of Changes by PDCCH.
When the information of carrying as MCCH changes, network side can be in beep-pager meeting, send a specific RNTI by PDCCH, for example M-RNTI (Multimedia-Radio Network TemporaryIdentifier, multi-media radio network temporary identifier).The user terminal that receives eMBMS business is waken up and is come to intercept the specific RNTI (as M-RNTI) on PDCCH according to the paging cycle of oneself.If detect on PDCCH and carried M-RNTI, represent that change has occurred the information on MCCH, user terminal can further be intercepted MCCH and be obtained new information.
In prior art one, when network side sends paging information bag to certain user terminal and while sending with the corresponding P-RNTI of paging information bag by PDCCH, within the same amendment cycle, only send once; In prior art two, when sending specific RNTI by PDCCH to certain user terminal, network side also only sends once within the same amendment cycle.
But, because PDCCH false retrieval or undetected probability are approximately one of percentage, therefore, cannot ensure that user terminal correctly receives MCCH Notification of Changes.In addition how the user that, above two kinds of methods do not define in connection status receives MCCH Notification of Changes.

Embodiment
Below in conjunction with the accompanying drawing in embodiments of the invention, the technical scheme in the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The sending method of the MCCH Notification of Changes of available technology adopting is owing to only sending MCCH Notification of Changes one time within the same amendment cycle, and the false retrieval of PDCCH channel or undetected probability are larger, cause user terminal may miss MCCH Notification of Changes, and then cannot obtain the business information after the variation of carrying on MCCH.For this problem, embodiments of the invention provide the sending, receiving method of MCCH Notification of Changes, base station within the same MCCH amendment cycle at least all beep-pagers in N paging cycle can on send MCCH notice of change, accordingly, user terminal is within each MCCH amendment cycle, in the situation that not receiving MCCH Notification of Changes, to attempt at least receiving MCCH Notification of Changes N time, the value of N is to be greater than 1 positive integer; The chance that receives like this MCCH Notification of Changes by increasing user terminal ensures that user terminal can receive MCCH Notification of Changes, and then ensures that user terminal obtains the reliability of the fresh information that MCCH carries.
Concrete, embodiments of the invention provide a kind of sending, receiving method of MCCH Notification of Changes, as shown in Figure 1, comprise the following steps:
Step 101, in the MCCH amendment cycle before the business information of carrying on MCCH changes, base station at least sends MCCH Notification of Changes in all paging subframes in N paging cycle within the described MCCH amendment cycle;
Step 102, when user terminal does not receive MCCH Notification of Changes within a MCCH amendment cycle, attempts at least receiving described MCCH Notification of Changes N time.
Concrete, when the user terminal in idle condition does not receive MCCH Notification of Changes within a MCCH amendment cycle, in its corresponding paging subframe, attempt at least receiving described MCCH Notification of Changes N time; When user terminal in connection status does not receive MCCH Notification of Changes within a MCCH amendment cycle, in the paging subframe within a MCCH amendment cycle, attempt at least receiving described MCCH Notification of Changes N time.
Introduce in detail the sending, receiving method of MCCH Notification of Changes provided by the invention below in conjunction with specific embodiment, comprise by beep-page message sending and receiving MCCH Notification of Changes and by two kinds of modes of PDCCH sending and receiving MCCH Notification of Changes, paper the first is by the mode of beep-page message sending and receiving MCCH Notification of Changes, as shown in Figure 2, comprise the following steps:
Step 201, when base station informing user terminal does not receive MCCH Notification of Changes within a MCCH amendment cycle, attempts at least receiving MCCH Notification of Changes N time.
Concrete, user terminal can be divided into the user terminal in connection status and the user terminal in idle condition.
For the user terminal in idle condition, the user terminal listening paging message of need to waking up in each paging cycle; If there is variation in MCCH, network side sends a beep-page message that comprises the instruction of MCCH Notification of Changes, and on PDCCH, send the P-RNTI that beep-page message is corresponding, when user terminal listens to the upper P-RNTI sending of PDCCH, obtain the MCCH Notification of Changes comprising in beep-page message, further arrive corresponding PDCCH position acquisition MCCH information after changing according to this MCCH Notification of Changes.Therefore, for the user terminal in idle condition, in the time that network side repeatedly sends MCCH Notification of Changes within the same MCCH amendment cycle, can wake up in each paging cycle listening paging message obtain MCCH Notification of Changes of user terminal, if the MCCH amendment cycle is M times of paging cycle, user terminal is intercepted M time MCCH Notification of Changes within a MCCH amendment cycle, thereby ensures that the user terminal in idle condition can get MCCH information after changing in time.
For the user terminal in connection status, which paging subframe listening paging message is prior art do not specify according to, can not ensure that user terminal receives the reliability of MCCH Notification of Changes.In the sending, receiving method of the MCCH Notification of Changes that embodiments of the invention provide, base station informing user terminal is attempted at least receiving MCCH Notification of Changes N time within a MCCH amendment cycle.Concrete, base station can by broadcast or multicast and broadcast control channel or in standard clearly the mode of regulation inform the UE in connection status in community, need within a MCCH amendment cycle, at least attempt receiving the times N of MCCH Notification of Changes.Because the UE under connection status has self specific paging cycle unlike the UE under idle (free time) state, therefore the UE of connection status can select each paging subframe in the MCCH amendment cycle to check whether have MCCH Notification of Changes.
Wherein, the number of times of N is subject to various factors, paging cycle length that the amendment Cycle Length of such as MCCH, the public paging cycle length of community, different user terminals are different etc., the occurrence of N can be arranged according to actual needs flexibly by user, this application scene only provides preferably implementation, determine the value of N divided by the public paging cycle length of community by the length in MCCH amendment cycle in MBSFN region, or MCCH revises the length in cycle divided by the public paging cycle of maximum of small area, MBSFN region.
Step 202, in the time that the business information of carrying on MCCH changes, base station comprises MCCH Notification of Changes in the beep-page message sending to user terminal.
Concrete, the user terminal for each in idle condition receives one time beep-page message in each paging cycle of this user terminal.For base station side, each beep-pager can corresponding one or more user terminals, base station need to be in paging position corresponding to user to user to sending beep-page message.In this application scene, in the time that the information of carrying on MCCH changes, base station comprises MCCH Notification of Changes in beep-page message, by beep-page message, MCCH Notification of Changes is sent to user terminal.
Step 203, base station is arranged in the MCCH amendment cycle and sends the beep-page message that comprises MCCH Notification of Changes and the number of times that sends P-RNTI by PDCCH.
For beep-page message and the P-RNTI that can ensure to comprise MCCH Notification of Changes arrive user terminal, base station need to provide repeatedly for each user the receiver meeting of beep-page message and P-RNTI.Because the user terminal in idle condition only can receive one time beep-page message in each paging cycle, therefore, base station need to be at least sending identical beep-page message and P-RNTI in N paging cycle.
The occurrence of N need to be set flexibly according to actual conditions, the value of determining N in this application scene with the length in MBSFN region MCCH amendment cycle divided by the public paging cycle length of community or the length in MCCH amendment cycle divided by the public paging cycle of maximum of small area, MBSFN region, N gets the integer value that is greater than 1.
Step 204, base station at least sends identical beep-page message and P-RNTI in N paging cycle within a MCCH amendment cycle.
Concrete, in base station, timer or counter can be set, time span or the message transmission times of the beep-page message that carries MCCH Notification of Changes sending for accounting base-station, determine whether base station reaches the threshold value that sends beep-page message.
For example, taking timer as example, the time span that need to send beep-page message and P-RNTI can be determined in base station according to the value of the length of each paging cycle and N, and this time span is set in timer.When base station starts to send while carrying the beep-page message of MCCH Notification of Changes and P-RNTI, timer starts timing, in the time that timer timing arrives default time span, wait various ways prompting base station to reach default beep-page message and P-RNTI transmitting time by warning, base station has completed the transmission of the interior beep-page message of N paging cycle and P-RNTI.
Taking counter as example, base station arranges the maximum of counter according to the number of times of beep-pager meeting in each paging cycle, suppose that the beep-pager in each paging cycle can be 10, and in N paging cycle, the number of times of beep-pager meeting comes to 10N.Base station arranges the maximum 10N of this counting in counter, in the time that within the MCCH amendment cycle, in N paging cycle, the transmission times of beep-page message and P-RNTI reaches 10N in base station, counter prompting base station has reached default maximum beep-page message and P-RNTI transmission times, and base station completes the transmission of the interior beep-page message of N paging cycle and P-RNTI.
Step 205, user terminal is intercepted the P-RNTI on PDCCH, at least attempts intercepting P-RNTI N time before not receiving P-RNTI.If user terminal has listened to P-RNTI, execution step 206; Optionally, if user terminal does not all listen to P-RNTI N time, perform step 207.
Concrete, for the user terminal in idle condition, each paging cycle all can be waken up and intercept P-RNTI, therefore, can ensure to intercept the reliability of P-RNTI, still, in order to reduce the number of times of the unnecessary P-RNTI of intercepting of user terminal in idle condition, this application scene adopts identical processing mode to the user terminal in idle condition with in the user terminal of connection status, if listen to P-RNTI, and execution step 206; Otherwise, optional, execution step 207, step 207 can arrange according to actual needs flexibly.
Step 206, user terminal receives the beep-page message that base station sends, and obtains MCCH Notification of Changes, further obtains the information after changing of carrying on MCCH according to this MCCH Notification of Changes.
For reducing the unnecessary number of times of intercepting, user terminal is successfully listening to after P-RNTI, within the current MCCH amendment cycle, stops intercepting the P-RNTI on PDCCH.
Step 207, user terminal judges that the information of carrying on MCCH in the current MCCH amendment cycle does not change, and no longer continues to intercept P-RNTI in the current MCCH amendment cycle.
Introduce the second sends MCCH Notification of Changes mode by PDCCH below, as shown in Figure 3, comprise the following steps:
Step 301, when base station informing user terminal does not receive MCCH Notification of Changes within a MCCH amendment cycle, at least attempts N time and receives MCCH Notification of Changes.
Step 302, in the time that the business information of carrying on MCCH changes, base station in MCCH at least N paging cycle in amendment cycle in all beep-pager meeting, by PDCCH send preset for identifying the specific RNTI of MCCH Notification of Changes.
Concrete, this specific RNTI can arrange according to actual needs flexibly, for example, can be set to M-RNTI (Multimedia-Radio Network Temporary Identifier, multi-media radio network temporary identifier).Similar to step 203, in base station, timer or counter can be set, send time span or the transmission times of specific RNTI for accounting base-station, determine whether base station reaches the threshold value that sends RNTI, whether base station completes at least transmission of N the interior specific RNTI of paging cycle.
The process that sends P-RNTI and beep-page message due to base station in the processing procedure of this step and step 202-step 204 in N paging cycle is at least same or similar, can, with reference to above-mentioned steps 202-step 204, no longer repeat at this.
Step 303, user terminal is intercepted the specific RNTI on PDCCH, at least attempts intercepting for N time specific RNTI not receiving before this specific RNTI.If user terminal has listened to specific RNTI, execution step 304; Optionally, if user terminal does not all listen to specific RNTI N time, perform step 305.
For the user terminal in idle condition or connection status, all need in beep-pager meeting, intercept specific RNTI, in order to reduce the unnecessary number of times of intercepting specific RNTI of user terminal, this application scene adopts identical processing mode to the user terminal in idle condition with in the user terminal of connection status, if listen to specific RNTI, execution step 304; Otherwise, optional, execution step 305, whether step 305 can arrange flexibly and carry out according to actual needs.
Step 304, user terminal is further intercepted PDCCH, obtains the Notification of Changes of the MCCH wherein carrying.
Successfully listening to once after specific RNTI, user terminal no longer continues to intercept the specific RNTI on PDCCH within the current MCCH amendment cycle, to reduce the unnecessary number of times of intercepting.
Step 305, user terminal judges that the information of carrying on MCCH in the current MCCH amendment cycle does not change, and no longer continues to intercept the specific RNTI on PDCCH in the current MCCH amendment cycle.
By the method that provides of embodiments of the invention is provided, in the MCCH amendment cycle before the business information of carrying on MCCH changes, base station at least sends MCCH Notification of Changes in all paging subframes in N paging cycle within this MCCH amendment cycle; Meanwhile, when user terminal does not receive MCCH Notification of Changes within a MCCH amendment cycle, attempt at least receiving this MCCH Notification of Changes N time; Thereby increase the chance of user terminal reception MCCH Notification of Changes, to ensure that user terminal receives the reliability of MCCH Notification of Changes.
