Description

Have multicast service travelling carriage sleep state machine activation and cancel Activiation method

Technical field

The present invention relates to the communications field, relate in particular to a kind of activation of the MSS sleep state machine with multicast service and cancel Activiation method.

Background technology

Fast development along with Internet, a large amount of multimedia services emerge, the some of them applied business requires a plurality of users can receive identical data simultaneously, also promptly data are carried out multicast, related applied business then comprises video request program, television broadcasting, video conference, online education, interactive game etc.Multicast service is a kind of from the technology of a data source to a plurality of targets transmission data, comprises multicast and broadcasting.802.16 up-to-date draft agreement IEEE802.16e/D8 in introduced multicast broadcast service (MBS, Multicast andBroadcast Service).The MBS business provides the standard that is sent data in the mobile network by a data source to a plurality of users, for providing a data source, the mobile network sends the point-to-multipoint service of data to a plurality of users, realized that Internet resources are shared, improved utilization rate of network resource, the interface resource of especially eating dishes without rice or wine.The MBS business can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and this has complied with the trend of following mobile data development undoubtedly.

For the MBS business that the IEEE802.16 agreement proposes, its network configuration as shown in Figure 1.Among Fig. 1, for supporting the MBS business, increased the mobile network functional entity newly---broadcasting multicast service server (MBSserver), it is content provider's inlet on the one hand, will plan the transmission of multi-case data of self subordinate's base station (BS) on the other hand, and the distribution multi-case data is given self BS of subordinate.In addition, also need functional entitys such as travelling carriage (MSS), BS are strengthened, promptly increase professional relevant function with MBS.

The MBS business operation mainly comprises following components: obtain MBS service lists information, to the authentication of MBS business and obtain encryption key, normally receive the MBS business.That is to say, normal receive the MBS business before, MSS at first needs to obtain from MBS server information such as MBS contents list, and then request BS carries out authentication to receiving the MBS business tine; After authentication was passed through, BS can send information such as comprising MBS downlink business parameter to MSS, can ask BS to return the MBS key after the MSS.MSS can utilize the relevant media access layer protocol Data Unit (MAC PDU) of message pick-up that obtains after obtaining downlink business parameter and MBS key, enter the professional accepting state of normal MBS.

In mobile communication system, the length of stand-by time has very large influence for the one-movement-freedom-degree of terminal.Prolongs standby time can realize that a kind of mode is to adopt battery efficiently by dual mode; Another kind method is to reduce the meaningless power consumption of portable terminal as much as possible.The mobile terminal sleeping pattern that defines in the D8 draft of IEEE802.16e just belongs to a kind of method in back.So-called sleep pattern is a portable terminal in the time interval of consulting in advance with the base station, the temporary transient process of getting in touch with the base station of interrupting of eating dishes without rice or wine.Realize that sleep mode procedures can reduce the transmission request of portable terminal on up link and down link, thereby reduce the power consumption of MSS.

MSS can initiatively send the MOB_SLP_REQ message request to serving BS broadcasts and enter sleep pattern, serving BS broadcasts transmission MOB_SLP_RSP response message is agreed or refuses MSS to enter sleep pattern then, also can initiatively send sleep response message (MOB_SLP_RSP) by BS and come requirement MSS to enter sleep pattern.

Present draft agreement version regulation, MSS and BS confer, and current service flow is divided into 3 class sleep groups according to its qos requirement and characteristic, and each class sleep group is taked different sleep strategies respectively.Each class can comprise a plurality of sleep groups, identical sleep strategy and the different sleep parameters of employing between the sleep group in the same class and the sleep group.Each sleep group can comprise a plurality of service flow.On behalf of the business between MSS and the BS, each service flow connect, and can be upstream or downstream, and the connection identifier (CID (CID) by one 16 bit identifies.The sleep state of each sleep group is divided into state of activation and unactivated state.Under state of activation, the sleep state machine of this sleep group normally carries out; Under unactivated state, the sleep state machine of this sleep group resets, and stops to carry out.Can there be a plurality of sleep groups in MSS, with the nonoverlapping time zone of the listen window of all sleep groups be unavailable interval (Unavailability interval), and Unavailability interval nonoverlapping At All Other Times the section be (Availability interval) between available area.MSS only is only in unavailable interval and really is in sleep state, and all sleep groups of this MSS all are in the sleeping window state.In between available area, can have some sleep group to be in the sleeping window state, other sleep group is in the state of intercepting, and MSS is in fact in waking state, and only the sleep state machine of each sleep group is under the different states.

First kind sleep group is defined as Power_Saving_Class_Type=1, its sleep strategy is to adopt fixing listen window length and variable sleeping window length, listen window and sleeping window are alternately, current sleeping window length is followed successively by 2 times of last sleeping window length, up to the maximum that reaches regulation, remain unchanged then and listen window hocket.Initiate sleep state change request up to MSS or BS, it is unactivated state that sleep state is set, and the sleep state machine of this sleep group just stops.

The second class sleep group is defined as Power_Saving_Class_Type=2, its sleep strategy is to adopt fixing listen window length and fixing sleeping window length, sleeping window and listen window alternately occur then, initiate sleep state change request up to MSS or BS, it is unactivated state that sleep state is set, and the sleep state machine of this sleep group just stops.

The 3rd class sleep group is defined as Power_Saving_Class_Type=3, the sleep strategy that it adopts is that sleeping window only is set one time, sleep state in this sleep group of the overtime back of sleeping window transfers unactivated state automatically to, the sleep state machine stops, and activates the sleep state machine of this group again by interacting message up to MSS or BS.This class sleep group is generally used for periodically search procedure, MBS business etc.

For first kind sleep group, BS can send service indication message (MOB_TRF_IND) during the listen window of this class sleep group, be used to refer to the business datum that whether has at the service flow of this sleep group.If the service indication message middle finger that each sleep group receives in Availability interval interval in the first kind sleep group among the MSS is shown with the business datum at this sleep group, then the sleep state of this sleep group becomes unactivated state, and the sleep state machine resets; If no, then the sleep state of this sleep group still is a state of activation, and the sleep state machine carries out as usual, enters sleep state after intercepting end; If the business datum at Business Stream in this sleep group is arranged, then the sleep state of this sleep group transfers unactivated state to, and the sleep state machine resets.

Fig. 2 is the sleep state schematic diagram that has two sleep groups among the MSS, and first sleep group belongs to first kind sleep group, and BS has distributed the listen window of regular length and has been followed successively by the sleeping window of 2 times of last sleeping windows; Second sleep group belongs to the second class sleep group, and BS has distributed the listen window and the sleeping window of regular length.Hatched example areas has shown the resultant effect of two class sleep groups, and wherein: hypographous oblique line interval is unavailable interval, and unblanketed oblique line interval is between available area.

For normal reception MBS business, mainly be meant and utilize the MBS downlink business parameter receive receiving course the MBS business tine.In present 802.16e/d8 draft.Introduced MBS-MAP message.It is as shown in table 1 that MBS shines upon the included information word of (MBS-MAP) message.
