Abstract
The invention discloses method for setting up sleep mode in mobile broadband wireless access system. Parameter information of sleep mode is carried by management message of traffic flow between mobile terminal and base station. When establishing or modifying traffic flow, the invention establishes or modifies sleep group based on parameter information of sleep mode carried by management message. The invention reduces redundant management message between MSS and BS when setting up sleep mode so as to save resources of aerial port.
Description
Technical field
The invention belongs to moving communicating field, relate in particular to the method that sleep pattern is set in mobile wide-band wire-less accessing system.
Background technology
IEEE 802.16e is the standard of mobile wide-band wire-less accessing system, in mobile wide-band wire-less accessing system, passes through radio communication between BS (Base Station, base station) and the MSS (Mobile Subscribe Station, travelling carriage). In when communication, BS and MSS require according to the different service quality of business datum and the characteristic that occurs is different is divided into different Business Streams, and for the characteristics of different business stream, arranges suitable chance transmission.
For reducing as much as possible the meaningless power consumption of MSS, IEEE 802.16e has defined a kind of mobile terminal sleeping pattern. Sleep pattern is MSS in the time interval of consulting in advance with BS, the temporary transient process that contacts with BS of interrupting. Realize that sleep mode procedures can reduce and move communicating by letter between MSS and the BS, between sleep period, MSS can intercept the downlink data of BS simultaneously, thereby reduces the power consumption of MSS.
MSS can initiatively send the MOB_SLP_REQ message request to Serving BS (serving BS broadcasts) and enter sleep pattern, then Serving BS transmission MOB_SLP_RSP response message is agreed or refuses MSS to enter sleep pattern, and BS also can initiatively send sleep response message (MOB_SLP_RSP) and come requirement MSS to enter sleep pattern.
According to the regulation of present protocol version, MSS and BS confer, and current Business Stream is divided into 3 class sleep groups according to its qos requirement and characteristic, and each class sleep group is taked respectively different sleep strategies. Each class can comprise a plurality of sleep groups, the identical sleep strategy of employing between the sleep group in the same class and the sleep group, but different parameters is arranged. Each sleep group can comprise a plurality of Business Streams. Each Business Stream identifies by the CID (Connection Identifier connection identifier) of 16 bits. 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, and only at all sleep group sleeping windows in the overlapping time, MSS just really is in sleep state, and the zone is called unavailable interval during this period of time. Section all is called between available area At All Other Times.
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, until reach the maximum of regulation, then remain unchanged and hocket with listen window. Change request until MSS or BS initiate sleep state, it is unactivated state that sleep state is set, and the sleep state machine of this sleep group just stops.
Equations of The Second Kind 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, then sleeping window and listen window alternately occur, until initiating sleep state, MSS or BS change request, 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, the sleep state of this sleep group is unactivated state after sleeping window is overtime, the sleep state machine stops, until MSS or BS reactivate the sleep state machine of this group by interacting message.
MSS can come to the new definition of BS request, revise or deletion sleep group by sending sleep request message MOB_SLP_REQ message. BS responds the sleep request of MSS by sending sleep response message MOB_SLP_RSP message.
According to existing protocol, the sleep group must be set up by SLP-REQ/RSP or other administrative messag after Business Stream is set up, and namely when Business Stream is set up, can not simultaneously Business Stream be added certain sleep group or newly set up a service groups. But in fact the characteristic of some Business Stream is just very clear and definite when Business Stream is set up, such as the business datum length of each appearance and the interval of data appearance etc. can add this Business Stream simultaneously certain sleep group of having set up or be the newly-built sleep group of this Business Stream when Business Stream is set up. Again for example, if certain has been included in the characteristic of the Business Stream in certain sleep group and has revised by DSC-REQ/RSP, possible this Business Stream is not suitable for continuing in this sleep group, in this case, according to existing protocol, just must finish or in the past, by the definition that SLP-REQ/RSP revises the sleep group, this Business Stream be removed from the sleep group at service flow modification. Therefore, existing sleep pattern setting up procedure has increased extra SLP-REQ/RSP message, has increased the communications burden of system.
Summary of the invention
