In LTE (Long Term Evolution, Long Term Evolution) system, MBMS has a variety of, enumerates several below:
1, Streaming Media, as: TV programme, sports broadcast.
The session of this class business continues several hrs usually.As: the session of a television channel correspondence can last till evening from the morning always.The session of sports tournament correspondence also can continue more than one hour usually.The modification of MCCH of correspondence that is to say this class business is at interval hour to be unit, and MCCH control information relevant in a day may only change several times.
2, file is downloaded, as: MMS (multimedia messaging service, MMS (Multimedia Message Service))
Consider the ability of LTE system and common file size, the download time of most of files is generally several seconds or a few minutes.The modification of MCCH information that is the correspondence of this class business is spaced apart several seconds or a few minutes.The change frequency of relevant MCCH control information can be too not high, as: per half an hour or per hour change once.
3, news flash, information for the game, transport information, weather forecast etc.
The data volume that this type service sends is less, upgrades regularly usually, as: a few minutes or half an hour.Upgrading at the MCCH of this class business or minute to be unit with second.The change frequency of relevant MCCH control information is higher relatively, as: per 5 minutes or change once per half an hour.
According to above-mentioned 3 kinds of professional corresponding MCCH change frequencies, MBMS can be divided into different business control information types.
Except the business control information type, also has a kind of MBMS common control information type.MBMS common control information type is meant the class control information of knowing that all relevant MBMS of all these MCCH of reception need when professional, such as: the pairing RLC of the logic channel of transport service (Radio Link Control, Radio Link control) layer parameter, transmit the employed MSAP of MCH (MCH Subframe Allocation Pattern, the sub-frame allocation pattern of MCH) of this MCCH related service etc.
MBMS control information type is business control information type and/or MBMS common control information type like this.In the corresponding relation of MBMS control information and MBMS control information type, the business control information type can be divided according to the change frequency of professional phase related control information, and promptly the business that frequency range is close can be divided into a class; MBMS common control information type can be set as required.
Certainly, in specific implementation process, the business control information type also can be set as required.
That is to say that the corresponding relation of MBMS control information and MBMS control information type can be set as required in advance.
The embodiment of the invention is by the corresponding relation of MBMS control information and MBMS control information type, user terminal is just monitored MCCH when the MBMS control information type of the interested MBMS control information correspondence of discovery self changes, thereby reduced the user terminal unnecessary electric quantity consumption.
Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 1, the communication system of the embodiment of the invention comprises: network equipment 10 and user terminal 20.
As shown in Figure 2, the network equipment of the embodiment of the invention comprises: control information type determination module 100 and indication information sending module 110.
Control information type determination module 100 is used for the corresponding relation according to MBMS control information and MBMS control information type, determines the MBMS control information type of the MBMS control information correspondence that changes.
Indication information sending module 110, be used for to the send control information variation indication information of the MBMS control information type correspondence that type determination module 100 determines of user terminal, be used for indicating user terminal and obtain MBMS control information after the variation according to the variation indication information of receiving.
Wherein, changing indication information can be RRC (Radio Resource Control, Radio Resource control) message content or physical layer message content.
If when changing indication information and being physical layer message, then user terminal with the signal that receives through the demodulation sign indicating number after, can directly determine the information of correspondence according to the binary coding that solves; If changing indication information is rrc layer message, then user terminal must pass through the information of receiving and just can obtain corresponding information after upper-layer protocol (as: MAC, RLC) is handled.
Further, changing indication information can adopt bit mapping or coded system to represent.
Mode one, variation indication information adopt bit mapping mode to represent.
The network equipment of the embodiment of the invention can further include: adjusting module 120.
Adjusting module 120, be used for after control information type determination module 100 is determined MBMS control information type, indication information sending module 110 sends and changes before the indication information, adjusts the parameter of MBMS control information type corresponding bit in changing indication information of determining.
Wherein the MBMS control information of the parametric representation MBMS control information type correspondence of adjusted bit changes.
Under this mode, changing in the indication information has a plurality of relevant indication information bit, the corresponding bit of each type of service, in addition, the also corresponding indication bit of universal class.Determine the business of desired reception in the variation indication information and/or the bit of general information correspondence when user terminal variation has taken place, so just remove to read MCCH, if the variation of MCCH is not because business and/or the general information be concerned about cause, will not read MCCH so.
In specific implementation process, whether exist the indication bit of MBMS common control information type correspondence to set as required, as: the information in the MBMS common control information type can be covered in each type of service, at this moment, the indication bit of MBMS common control information type correspondence will do not had.
Concrete mapping mode can design according to actual needs.
Possible paging (paging) message is as follows:
Paging::＝ SEQUENCE{
pagingRecordList PagingRecordList OPTIONAL，--Need?ON
systemInfoModification ENUMERATED{true}OPTIONAL，--
NeedON
MCCHInfoModification BIT?STRING(size(4)) OPTIONAL，
--NeedON
etws-Indication ENUMERATED{true}OPTIONAL，--
NeedON
nonCriticalExtension SEQUENCE{}OPTIONAL --Need?OP
}
The message structure here is (other definition mode can be suitable for the embodiment of the invention equally, gives unnecessary details no longer one by one at this) of adopting abstract syntax notation one (ASN.1, Abstract Syntax Notation One) rule to define.The meaning is: Paging message is a SEQUENCE (sequence); Comprise 5 variablees (pagingRecordList, systemInfoModification, MCCHInfoModification, etws-Indication, nonCriticalExtension) in this sequence; The attribute of the variable MCCHInfoModification that the embodiment of the invention is added is: the BIT STRING (bit strings) of a 4bit, the meaning of OPTIONAL--Need ON is whether it occur in Paging message is OPTIONAL (optional), and receiving terminal is normally carried out other processes when not occurring.
That is to say, changing indication information under this mode generates in advance, change all corresponding MBMS control information type of each bit in the indication information, the length (size) that is the pairing BIT STRING of MCCHInfoModification is how much determining by the MBMS control information type of dividing, such as 3 MBMS control information types are arranged now, it is respectively a MBMS control information type, the 2nd MBMS control information type and the 3rd MBMS control information type, " 1 " expression changes, " 0 " expression does not change, then initial variation indication information is 000, suppose that the 3rd MBMS control information type changes, and corresponding the 3rd 0 of the 3rd MBMS control information type, then adjusted variation indication information is 001; Suppose that the first and the 3rd MBMS control information type changes, then adjusted variation indication information is 101.
Mode two, variation indication information adopt coded system to represent.
Adjusting module 120, be used for after control information type determination module 100 is determined MBMS control information type, indication information sending module 110 sends and changes before the indication information, according to the corresponding relation of MBMS control information type and running parameter, with the running parameter of the MBMS control information type correspondence determined as changing indication information.
Under this mode, first kind business is 001, the second class business is 010, it is 011 that the MCCH that non-business is relevant revises (as: the pairing control information of MBMS common control information type changes), multiclass is professional to be changed MCCH that (can comprise that the pairing control information of MBMS common control information type changes) cause and is revised as 100 etc., to carry more information.Concrete coded system can design according to actual needs.
Possible paging message is as follows:
Paging::＝ SEQUENCE{
pagingRecordList PagingRecordList OPTIONAL，--Need?ON
systemInfoModification ENUMERATED{true} OPTIONAL，--
NeedON
MCCHInfoModification BIT?STRING(size(3)) OPTIONAL，
--NeedON
etws-Indication ENUMERATED{true} OPTIONAL，--
NeedON
nonCriticalExtension SEQUENCE{} OPTIONAL --Need?OP
}
That is to say that changing indication information is to generate according to the MBMS control information type that changes.Such as 3 MBMS control information types are arranged now, it is respectively a MBMS control information type, the 2nd MBMS control information type and the 3rd MBMS control information type, the one MBMS control information type is 001, the 2nd MBMS control information type 010, the 3rd MBMS control information type is 011, supposes that the 3rd MBMS control information type changes, and then changing indication information is 011; Suppose that the first and the 3rd MBMS control information type changes, then adjusted variation indication information is 001011.
Mapping or coded system can reduce the number of times that MCCH was monitored and read to user terminal under the very little situation of signaling consumption increase.
Wherein, the indication information sending module adopts a kind of the transmission to user terminal in the following manner to change indication information:
(a) will change indication information and place P-RNTI (Paging-Radio Network Temporary Identifier, paging-Radio Network Temporary Identifier) Dui Ying PDSCH (Physical Downlink Shared Channel, downlink physical shared channel) goes up in the rrc layer Paging message of transmitting and sends;
(b) will change the rrc layer message that indication information places the pairing PDSCH of a RNTI to go up transmission and send, wherein a RNTI indicates whether to exist Paging and relevant RNTI that whether multicast control channel MCCH content changes simultaneously;
(c) will change indication information places the physical layer message of the last transmission of the 2nd RNTI corresponding physical downlink sharied signal channel PDSCH to send;
(d) will change indication information places the RRC message of the last transmission of PDSCH of the 2nd RNTI correspondence to send;
(e) will change DCI (descending control signaling) transmission that indication information places the 2nd RNTI correspondence;
The 2nd RNTI is irrelevant with paging message, be used to indicate whether the relevant RNTI that the MCCH content changes, can be expressed as MICH-RNTI (MBMS notification Indicator Channel-RNTI, MBMS informing indication channel-Radio Network Temporary Identifier) or MI-RNTI (MBMS notification Indicator-RNTI, MBMS notifies indication-Radio Network Temporary Identifier) etc.
Wherein, indicating whether to adopt a and b under the situation that the MCCH content changes with call signaling combines.
The main distinction of a and b is: have only one with the MCCH content relevant RNTI that whether changes in a, that is: P-RNTI changes indication information and realizes by increase new variable in original paging message; Can have three with the MCCH content relevant RNTI that whether changes in b, three the one RNTI are used to refer to respectively:
(1) paging but MCCH do not change; (2) paging and MCCH change; (3) MCCH changes not paging, when occur that indication MCCH changes RNTI the time, change indication information and realize by the new variable of increase in the RRC of correspondence message (can adopt the structure of similar paging message).
Under the situation that the 2nd RNTI that employing is independent of the paging signaling indicates MCCH to change, can adopt c, d and e.
The common ground of a and b is all relevant with paging message; The common ground of c, d and e is all irrelevant with paging message.
Need to prove that the embodiment of the invention is not limited to the mode that above-mentioned transmission changes indication information, any mode that the variation indication information can be sent to user terminal all is to use the embodiment of the invention.
Wherein, can determine corresponding MBMS control information according to MBMS control information type in order to guarantee user terminal, make user terminal determine whether to monitor control information among the MCCH, the corresponding relation of MBMS control information and MBMS control information type can be saved in other entities, supply the network equipment and the user terminal of the embodiment of the invention to call.Certainly, also the corresponding relation of MBMS control information and MBMS control information type can be saved in respectively in network equipment and the user terminal, then network equipment also needs the corresponding relation of MBMS control information and MBMS control information type is informed terminal.The network equipment of the embodiment of the invention can further include: notification module 130.
In specific implementation process, notification module 130 can adopt a kind of informing user terminal MBMS control information in the following manner and the corresponding relation of MBMS control information type:
Place broadcast to send the corresponding relation of MBMS control information and MBMS control information type;
Send the corresponding relation of MBMS control information and MBMS control information type by MCCH.
Need to prove that the embodiment of the invention is not limited to above-mentioned advice method, any can all be to use the embodiment of the invention with the mode of the corresponding relation informing user terminal of MBMS control information and MBMS control information type.
In specific implementation process, the concrete indication information that changes adopts any mode to represent, adopt which kind of mode to send and change indication information to terminal, and the corresponding relation that adopts which kind of mode informing user terminal MBMS control information and MBMS control information type, can in agreement, stipulate, also can determine by the negotiation between network equipment and the user terminal.
The network equipment of the embodiment of the invention can be the base station, also can be other equipment of network side, can also be the new equipment of network side.
As shown in Figure 3, the user terminal of the embodiment of the invention comprises: receiver module 200, processing module 210 and acquisition module 220.
Wherein, MBMS control information type is business control information type and/or MBMS common control information type.
Because the MBMS common control information in the MBMS common control information type is not at certain business, but whole M CCH, if so the MBMS common control information in the MBMS common control information type changes, then user terminal need obtain the MBMS common control information after the variation.If i.e. MBMS control information type is a MBMS common control information type (is that MBMS control information type is the situation of MBMS common control information type, and MBMS control information type is the situation of MBMS common control information type and business control information type), then acquisition module 220 is after processing module 210 is determined the MBMS control information, just monitor MCCH, and from MCCH, obtain corresponding M BMS control information.
For the business control information type, if the variation indication information corresponding service type that user terminal receives is not to receive the professional needed business control information corresponding service control information type of current MBMS, the business control information that then obtains without any use, that is to say that current monitoring MCCH is without any meaning for self.
In order to reduce the monitoring number of times without any meaning, if MBMS control information type is a business control information, then the user terminal of the embodiment of the invention can further include: trigger module 230.
Accordingly, acquisition module 220 is the business control information type in MBMS control information type, and after trigger module 230 triggers, monitors MCCH, and obtain corresponding M BMS control information from MCCH.
