Problems solved by technology

[0012] It can be seen that in the existing MBS_MAP_IE, the definition of SLC 3_indication=1 and the parameters Next MBS frame offset and Next MBS OFDMA Symbol offset will make the mobile terminal must be in the frame listening position at the subsequent frame time when the base station sends the MBS_MAP message. State and can not be in sleep state, in order to receive MBS_MAP message, and because MBS_MAP message is actually a redundant message for mobile terminal, therefore, reduce the sleep time of mobile terminal, increase the power consumption of mobile terminal, reduce freedom of movement of the mobile terminal, and reduces the performance of the mobile terminal

Embodiment 1

[0044] figure 1 This is a flow chart of reducing power consumption of a mobile terminal in Embodiment 1 of the present invention. see figure 1 , when the mobile terminal adopts the sleep mode and receives multicast service data in a non-macrodiversity manner, the process of reducing the power consumption of the mobile terminal of the present invention specifically includes the following steps:

[0045] Step 101: In the MBS_MAP_IE, set a parameter instructing the mobile terminal to obtain the multicast service resource only according to the MBS_MAP_IE.

[0046] Here, because in the prior art, the parameter SLC 3_indication=1 is used to indicate that the mobile terminal adopts the sleep mode and needs to indicate the frame position of the subsequent MBS_MAP message, that is, the parameter SLC 3_indication=1 will indicate that the mobile terminal is in the subsequent process. Receive redundant MBS_MAP messages, and obtain multicast service resources again according to the MBS_M...

Embodiment 2

[0077] figure 2 This is a flow chart of reducing the power consumption of the mobile terminal in Embodiment 2 of the present invention. see figure 2 , when the mobile terminal adopts the sleep mode and receives multicast service data in a non-macrodiversity manner, the process of reducing the power consumption of the mobile terminal of the present invention specifically includes the following steps:

[0078] All descriptions of steps 201 to 203 are the same as those of steps 101 to 103 .

[0079] Step 204: At the frame moment when the base station sends the multicast service data to the mobile terminal, the base station sends the downlink message carrying the MBS_MAP_IE and the multicast service data to the mobile terminal.

[0080] Here, the downlink message may be an existing DL_MAP message or a self-defined message of the present invention.

[0081] In addition, in this step 204, the difference between the MBS_MAP_IE carried in the downlink message and the MBS_MAP_IE c...

Abstract

The invention discloses a system for reducing power consumption of a mobile terminal and the mobile terminal. The system comprises a base station and the mobile terminal; the base station is used for sending downlink information carrying a multicast service mapping information element which comprises frame position information of a next multicast service mapping information element corresponding to a multicast service; the mobile terminal is used for receiving the downlink information carrying the multicast service mapping information element, obtaining multicast service data according to the multicast service mapping information element and setting self-sleep period according to the frame position, and receiving the next multicast service mapping information element after the sleep period. In the method, the mobile terminal does not need to receive multicast service mapping messages, but only receives each multicast service mapping information element for obtaining multicast service resources, thus increasing sleep time of the mobile terminal and reducing the power consumption of the mobile terminal.

Description

[0001] This application is a divisional application with an application number of 200680012305.8 and an application date of June 15, 2006, and the title of the invention is "a method for reducing power consumption of a mobile terminal". technical field [0002] The present invention relates to mobile communication technology, in particular to a method for reducing power consumption of mobile terminals in multicast broadcasting service. Background technique [0003] Multicast broadcast (MBS, Multicast and Broadcast Service) service is a multimedia service application proposed by the latest protocol draft of 802.16, IEEE802.16e / D8. The MBS service provides a point-to-multipoint service specification for sending data from a data source on the network side to multiple mobile terminals in a mobile network, realizes network resource sharing, and improves the utilization rate of network resources, especially the air interface resources. utilization. In addition, the MBS service ca...
