For the ease of understanding the technical scheme that the embodiment of the invention provides, before the technical scheme that the embodiment of the invention is provided is introduced, at first the system information that the embodiment of the invention is related to, paging occasion (Paging Occasion abbreviates PO as) and MBMS announcement information are simply introduced.
1. system information
In the LTE system, system information is the important source that UE is known the high-rise control information of network side, also is the important means that network side is controlled/disposed UE.
Broadcast Control Channel (Broadcast Control Channel, abbreviating BCCH as) message is as the general designation of system information, specifically can be divided into Master Information Block (Master Information Block, abbreviate MIB as), system information block 1 (System Information Block 1, abbreviate SIB1 as) and other block of information (other SIBs, for example, SIB2, SIB3, SIB4......SIB11, SIB12 etc.).
In the system information process of transmitting, system information will be with notifications (System Information, abbreviating SI as) form of message sends in it sends window, other SIB except that MIB and SIB1 will be mapped on the SI and send, and concrete SIB will provide on SIB1 to the mapping relations of SI.The prerequisite of UE persistent district is a receiving system information, and will obtain system information from network side with the form of MIB, SIB1 and SI, and with its source as high-rise control information important in this sub-district; Behind the UE persistent district, just can begin to receive MCCH message, monitor the MBMS announcement information or carry out other operations.
2. paging occasion
The realization of LTE paging mechanism realizes by sending beep-page message, the UE that has resided in the sub-district searches the paging information that whether has at it by monitoring beep-page message, wherein, the position that UE monitors beep-page message is called paging occasion (Paging Occasion, abbreviate PO as), PO is 1 subframe on time-domain;
For network side and UE, particular location network side and the UE of PO are known in advance, specifically can realize sending the unification of position and monitoring position by fixing algorithm, it is network side sends this UE in a certain subframe position paging information, this UE just in time detects its beep-page message in this subframe position, specifically can realize by the constraint of radio frames level and sub-frame level; For a certain UE, in paging cycle, only there is a subframe position to be its PO position, this position can be by global mobile user identification (the International Mobile Subscriber Identity of UE, abbreviate IMSI as) and paging cycle length determine that specific implementation is to retrain by above-mentioned algorithm.For the UE that is in idle condition, this UE will and belong on its PO at each paging cycle and detect beep-page message.
3.MBMS the communication information
When UE just starts shooting or owing to its mobility enters a new MBMS Single Frequency Network (MBMS over a Single Frequency Network abbreviates MBSFN as) zone, UE will read MCCH message (MCCH information); Subsequently, network side informs that by sending MBMS announcement information (for example, MCCH notice indication) change has taken place UE (the being also referred to as MBMS idle UE) MCCH that obtains MCCH message but do not receive the MBMS business; That is to say that the UE that does not receive the MBMS business monitors the MBMS announcement information, if received the MBMS announcement information, UE just receives MCCH message after changing; Otherwise UE can not go to read the MCCH message that change does not take place.
According to the embodiment of the invention, at first provide a kind of MBMS announcement information to send the indicating means of position.
Fig. 1 is the flow chart that sends the indicating means of position according to the MBMS announcement information of the embodiment of the invention, and as shown in Figure 1, the indicating means that sends the position according to the MBMS announcement information of the embodiment of the invention mainly may further comprise the steps (step S101-step S103):
Step S101: network side sends high-level signaling, and wherein, this high-level signaling has been indicated the transmission position of MBMS announcement information;
Particularly, network side can send above-mentioned high-level signaling with broadcast mode the mode of multiple spot (more promptly to), also can send above-mentioned high-level signaling with mode of unicast.
Step S103: the MBMS announcement information is monitored in the transmission position of this high-level signaling indication in the terminal periodic ground that receives above-mentioned high-level signaling.
Below further describe the processing of above steps.
In specific implementation process, network side can pass through the transmission position of the indication MBMS announcement information of high-level signaling dominance, also can pass through the transmission position of the indication MBMS announcement information of high-level signaling recessiveness, respectively this dual mode is described below.
(1) dominant mode
Network side adopts under the situation of dominant mode, network side carries the indication information of the transmission position of indication MBMS announcement information in high-level signaling, particularly, can on high-level signaling, dispose an information unit (Information Element, abbreviate IE as), this information unit is used to indicate the transmission position of MBMS announcement information, particularly, the concrete subframe position that can the indication network side sends the MBMS announcement information, for example, subframe numbers etc., perhaps, this indication information also can be the information of the position that consults in advance of indication network side and terminal, and for example, the position that the indication network side sends the MBMS announcement information is the network side subframe that sends the MCCH place etc.
And, under the situation of dominant mode indication, network side can also carry listening period in this high-level signaling, indication UE periodically monitors the MBMS announcement information according to this listening period, in specific implementation process, this listening period can be revised cycle, MCCH repetition period, paging cycle etc. for MCCH.
Terminal is the cycle to carry listening period in this high-level signaling after receiving above-mentioned high-level signaling, periodically monitors the MBMS announcement information in the indicated transmission position of above-mentioned information unit.
Adopt this indicating mode, network side both can send the MBMS announcement information in the PO position, also can send the MBMS announcement information in other position that is different from the PO position, both network side both can send the MBMS announcement information in the PO subframe, also can send the MBMS announcement information in other subframe that is different from the PO subframe, indicate in high-level signaling as long as network side is sent the position of MBMS announcement information, terminal just can be monitored the MBMS announcement information in the position that network side sends the MBMS announcement information according to indication information in the high-level signaling.
Consider and reduce the signaling consumption of high-level signaling when the transmission position of notifying MBMS announcement information, high-level signaling can indicate position that a network side and terminal consulted in advance (for standard operation in indication information, this position can be fixed on agreement), for example, the value of the information unit that network side can dispose high-level signaling is changed to 1, and the indication network side will send transmission MBMS announcement information on the subframe of MCCH place; Like this, high-level signaling can use seldom that the bit number (for example, 1bit) comes the transmission position of notifying MBMS announcement information; Adopt this method can reduce the signaling consumption of high-level signaling, therefore,, in practicing, also be easier to be adopted though this mode has reduced the flexibility ratio of allocation position in indication MBMS announcement information transmission position.
If network side sends the MBMS announcement information in other position that is different from the PO position, then UE is according to the indication of the above-mentioned information unit in the high-level signaling, in other position that is different from the PO position, other subframe that promptly is different from the PO subframe is waken up extraly and is detected the MBMS announcement information, the PO subframe that can stagger so can not cause the nervous or conflict of resource in the PDCCH common search space of PO subframe.
(2) recessive mode
Adopt recessive mode indication network side to send the MBMS announcement information and be meant that network side does not carry the indication information of the concrete transmission position of indication MBMS announcement information in the above-mentioned high-level signaling that sends, the indication network side sends the MBMS announcement information at the default location place, promptly network side adopts network side and all known default location of UE to send the MBMS announcement information.In this case, after UE receives this high-level signaling, monitor the MBMS announcement information at the default location place.
In specific implementation process, above-mentioned default location is the PO position, after UE receives above-mentioned high-level signaling, is the cycle with the paging cycle, periodically detects the MBMS announcement information on its PO position.
When adopting recessive mode, UE does not need to wake up extraly, can directly detect the MBMS announcement information on the PO position, thereby can save the electric weight of UE.
In specific implementation process, above-mentioned high-level signaling is meant but is not limited to one of following: BCCH information (BCCH message), MCCH information (MCCH message), Radio Resource control (Radio Resource Control, abbreviate RRC as) information (RRCmessage), media interviews control unit (Medium Access Control Control Element abbreviates MAC CE as) information.
In specific implementation process, if network side stresses to consider not increase extra the waking up opportunity of UE, then network side can adopt above-mentioned recessive mode to indicate the transmission position of MBMS announcement information, and at PO position transmission MBMS announcement information, promptly when the MCCH message alteration, network side sends the MBMS announcement information in the PO position; At this moment, do not obtain the transmission positional information of MBMS announcement information when UE reads high-level signaling, then UE will detect the MBMS announcement information at the PO place of each paging cycle; If network side stresses to consider can cause increasing PDCCH common search space expense and P-RNTI, SI-RNTI, M-RNTI collision probability appear in increase at PO place transmission MBMS announcement information, then network side can adopt the transmission position of above-mentioned dominant mode indication MBMS announcement information, and the concrete transmission position of MBMS announcement information is indicated in the relevant information unit that specifically can dispose on high-level signaling; Particularly, network side sends the indication information that the MBMS announcement information sends the position by high-level signaling, concrete subframe position and the listening period that sends of its indication information indication MBMS announcement information, this subframe can be MBMS Single Frequency Network subframe (multicast subframe) or unicast sub, and, network side is the cycle with this listening period, periodically sends the MBMS announcement information in this subframe position.
For the UE side, UE (is for example receiving above-mentioned high-level signaling, BCCH message, MCCH message, RRC message information or MAC CE information) time, UE reads high-level signaling, if disposed the information unit that indication MBMS announcement information sends the position on this high-level signaling, then UE periodically detects the MBMS announcement information on the indicated subframe position of this information unit; If do not dispose the information unit that indication MBMS announcement information sends the position on this high-level signaling, then UE detects the MBMS announcement information on the PO subframe position.
In specific implementation process, above-mentioned UE is for having obtained MCCH message but also do not begin to receive the UE of MBMS business.
The technique scheme that provides by the embodiment of the invention, when adopting dominant mode to indicate, the position that network side sends the MBMS announcement information can not be restricted, network side can be configured to the transmission subframe position of MBMS announcement information non-PO subframe also can be configured to the part or all of of PO subframe, no matter which subframe network side shows the transmission position of having indicated the MBMS announcement information on by the information unit in the high-level signaling, and UE needs to read the information unit in this high-level signaling and monitor the MBMS announcement information on its appointed positions.Be network side when adopting the transmission position of above-mentioned dominant mode indication MBMS notification message, the subframe of its indication can be a kind of of following three kinds of combinations: 1) only be non-PO subframe (comprise unicast sub and/or multicast subframe, be generally multicast subframe); 2) only be the part or all of of PO subframe; 3) any subframe.And when adopting above-mentioned recessive mode to indicate, network side can only send the MBMS announcement information on the PO subframe.
