Implement the mode of the present invention
Must be more clearly understood to express the object, technical solutions and advantages of the present invention, below in conjunction with the accompanying drawings and specific embodiment the present invention is further described in more detail.
In mobile terminal using sleep pattern and during by non-macro diversity mode receiving multicast traffic data, because base station can issue cast service data to mobile terminal simultaneously and carry MBS_MAP-IE DL-MAP message, therefore, at the time of MBS-MAP-IE is issued in base station, for receiving multicast traffic data, mobile terminal must wake up reception MBS-MAP-IE, will not unnecessarily reduce the length of one's sleep of mobile terminal.And in the prior art, mobile terminal is waken up at the time of MBS-MAP message must also be issued in base station, to obtain multiplaying service resource, and it is that can be obtained completely by the MBS_MAP_IE in DL-MAP message by the multiplaying service resource acquired in MBS-MAP message.It can be seen that, for mobile terminal, MBS-MAP message is actually the message of a redundancy, mobile terminal need to only obtain MBS-MAP-IE that base station is issued each time, just it can ensure to obtain specific multiplaying service resource each time, so as to normally receive the cast service data that base station is issued each time. '
For this feature, the present invention proposes a kind of method for reducing power consumption of mobile terminal, and its core concept is：A kind of any one MBS-MAP-IE of multicast service of correspondence is set to indicate the frame position of next MBS-MAP-IE to multicast service should be planted；MBS-MAP-IE and corresponding cast service data are sent to mobile terminal；Mobile terminal obtains cast service data according to the MBS_MAP-IE received, and the frame position of next MBS-MAP-IE according to indicated by the MBS_MAP-IE received sets the length of one's sleep length of itself；Mobile terminal receives next MBS-MAP-IE and cast service data after length of one's sleep length.
Wherein, realizing that the present invention is to carry MBS_MAP_IE to send in a downstream message to mobile terminal when MBS-MAP-IE is sent to mobile terminal.The downstream message can be that original DL-MAP message can also be customized message of the invention.
Also, in order to ensure that mobile terminal can accurately receive described next MBS-MAPJGE after length of one's sleep length, there are two kinds of specific embodiments in the present invention：Mode one, the frame offset parameter for indicating the next MBS-MAP-IE is set in described any one MBS-MAP-IE, symbol offset parameter and information word length parameter, and the value of next MBS-MAP-IE frame offset parameter is carried in the MBS-MAP sent to mobile terminal-IE, the value of symbol offset parameter and the value of information word length parameter, mobile terminal is after length of one's sleep length, next MBS-MAP-the IE obtained in downstream message is only received according to the value of the value of next MBS_MAP-IE symbol offset parameter and information word length parameter, rather than receive the downstream message of whole frame；Mode two, mobile terminal receive the downstream message of whole frame, and by the parsing to downstream message, next MBS-MAP-IE is obtained from downstream message.
In addition, it is necessary to explanation, in the present invention, involved MBS-MAP-IE and cast service data are for the multicast service corresponding to same multicast connection identifiers.
Then ensure that mobile terminal receives next MBS-MAP-IE two kinds of embodiments after length of one's sleep length for the present invention below, illustrate the complete implementation process of the present invention as an example respectively.

In order to avoid mobile terminal receives MBS-MAP message of redundancy, in this step, in MBS-MAP-IE, the parameter for indicating that mobile terminal only obtains multiplaying service resource according to MBS-MAP-IE is set, is implemented as：
Original parameter SLC-3-indication=1 in MBS-MAP-IE is redefined, arrange parameter SLC-3-indication=1, for representing mobile terminal using sleep pattern and next MBS-MAP-IE receiving position need to be indicated；Or, directly deleting parameter SLC_3-indication, and increase a customized parameter is used to represent mobile terminal using sleep pattern and need to indicate next MBS-MAP-IE receiving position.
So, the parameter of multiplaying service resource is only obtained according to MBS-MAP-IE by the instruction mobile terminal set by this step, base station then can be without sending MBS-MAP message to mobile terminal again, and the parameter for indicating next MBS-MAP-IE is only carried in MBS-MAP_IE, and mobile terminal then would know that the MBS_MAP message without receiving redundancy again, next MBS-MAP-IE is only received.
Step 102:In MBS-MAP-IE, the parameter Next MBS frame offset and Next MBS OFDMA Symbol offseto for indicating the specific receiving position of MBS-MAP message are deleted
Step 103:In MBS_MAPJE, the frame offset parameter for indicating next MBS-MAPJE frame positions is set.
Here, the frame offset parameter of next MBS-MAP-IE frame positions is indicated by setting, to indicate frame shifting amounts of the next MBS-MAP-IE relative to this frame MBS-MAPJE.Such as, the frame offset parameter for indicating next MBS-MAP-IE can be set to Next MBS-MAP-IE frame offseto
Step 104:In MBS-MAP-IE, the symbol offset parameter for indicating next MBS-MAP_IE is set.
Here, next MBS_MAP-IE symbol offset parameter is indicated by setting, to refer to
Show symbol offset amounts of the next MBS-MAP-IE relative to next frame head comprising MBS-MAPJE frames.Such as, the symbol offset parameter for indicating next MBS-MAP-IE can be set to Next MBS-MAP-IE OFDMA Symbol offset,
Step 105:In MBS-MAP-IE, the information word length parameter for indicating next MBS-MAPJE physical lengths is set.
Here, the information word length parameter of next MBS-MAP-IE physical lengths is indicated by setting, to indicate next MBS-MAP-IE specific length so that mobile terminal can set the time of intercept length of itself according to the specific frame length.Such as, in this step, information word frame length parameter can be set to Next MBS-MAP-IE Lengths
By step 101 to step 105, invention removes the parameters indicated in MBS-MAPJE using follow-up MBS-MAP message, and the parameter for indicating next specific receiving positions of MBS-MAP-IE and the information word length is added.
So far, the MBS-MAP redefined-IE has also just been correspondingly made available, its specific form can be found in shown in table 2.
