Abstract
The invention relates to a sensing method initiated by an MCBCS (Multicast Broadcast Service) server, comprising the following steps that: the MCBCS server sends a sensing request message to a base station; the base station sends the sensing request message to users in a cell after receiving the sensing request message; an MBS (Mutual Broadcasting System) user in the idle state sends a sensing message to the base station; and the base station sends a sensing result report message to the MCBCS server after sensing the sensing message transmitted from the MBS user. By adopting the method, the MCBCS server can highly-efficient learn that E-MBS users in each cell in the MBS region exist or not, thereby being capable of dynamically regulating the E-MBS region.
Description
Technical field
The present invention relates to comprise the cellular system of relaying, for example 802.16m system, the particularly cognitive method in the multicast and broadcast service.
Background technology
In existing 802.16 systems, Multimedia Broadcast Multicast Service (MBS) transmits in the multicast and broadcast zone.The MCBCS server is the core of multicast and broadcast service, and it is in charge of the work such as configuration in multicast and broadcast zone.The data source of multicast is issued the MCBCS server to data earlier, and then, the MCBCS server is issued base station in the multicast and broadcast zone to multicast content, and the base station the multicast and broadcast zone in is issued user in the multicast and broadcast zone to multicast content with frequency simultaneously.
The dynamic multicast broadcast service is to adjust the service of multicast and broadcast area size according to the distribution dynamic of multicast and broadcast user on the geographical position.In the 802.16m system,, therefore can't dispose the dynamic multicast broadcast service owing to can't monitor the E-MBS user's of idle condition particular location.
Summary of the invention
The purpose of this invention is to provide the cognitive method in a kind of multicast and broadcast service.
According to an aspect of of the present present invention, the cognitive method that a kind of MCBCS server is initiated comprises step:
A) the MCBCS server sends sensing request message to the base station;
B) base station receives that the user in the sub-district sends sensing request message after the sensing request message;
C) the MBS user of idle condition sends perception message to the base station;
D) send the sensing results report message to the MCBCS server after the perception message that perception MBS user in base station sends.
According to another aspect of the present invention, the cognitive method that initiate a kind of base station comprises step:
A) user of base station in the sub-district sends sensing request message;
C) the MBS user of idle condition sends perception message to the base station;
D) send the sensing results report message to the MCBCS server after the perception message that perception MBS user in base station sends.
By method of the present invention, the MCBCS server can understand efficiently whether each sub-district exists E-MBS user in the MBS zone, thereby can dynamically adjust the E-MBS zone.

Embodiment
The present invention proposes a kind of 802.16m system Multimedia Broadcast Multicast Service cognitive method.Accompanying drawing 1 has provided the flow process of the cognitive method of MCBCS server initiation, specifically comprises the steps:
101.MCBCS the base station of server in the MBS zone sends sensing request message;
102. after the base station receives sensing request message, check whether there is MBS user among the user who is in connection status in the sub-district,, then directly carry out 106, otherwise carry out 103 if exist;
103. the user of base station in the sub-district sends sensing request message;
104. after the user of idle condition receives sensing request message,, then send perception message, otherwise do not do action if oneself be MBS user;
105. the perception message that base station perception user sends;
106. the base station sends the sensing results report message to the MCBCS server, has MBS user if be in the user of connection status in the sub-district, perhaps the base station perceives the perception message that the user sends, and then sensing results is existence in the message; Otherwise sensing results is not for existing in the message.
Accompanying drawing 2 has provided the flow process of the cognitive method of base station initiation, specifically comprises the steps:
201. the user of base station in the sub-district sends sensing request message;
202. after the user of idle condition receives sensing request message,, then send perception message, otherwise do not do action if oneself be MBS user;
203. the perception message that base station perception user sends;
204. the base station sends the sensing results report message to the MCBCS server, if the base station perceives the perception message that the user sends, then sensing results is existence in the message; Otherwise sensing results is not for existing in the message.
Embodiment
The action behavior of user side (referring to Fig. 3).
301. the user receives the message from the base station, and judges type of message, if sensing request message then carries out 302;
302. if the user is in idle condition, then carry out 303;
303. if the user is MBS user, then carry out 304;
304. the user sends perception message to the base station.
The action behavior of base station end (referring to Fig. 4).
401. the base station receives the MCBCS server and sends, and judges type of message, if sensing request message then carries out 402;
402. the base station judges whether there is the MBS user who is in connection status in the sub-district, if exist then execution
404, otherwise carry out 406;
If reduce to 0 403. be in the MBS number of users of connection status in the discovery sub-district, base station, then carry out 404;
404. the user of base station in the sub-district sends message, the type of message is the perception request, and the MBS user that request is in idle condition sends perception message, makes the base station to understand and whether has the MBS user who is in idle condition in the sub-district;
405. the perception message that base station perception user sends; After finishing, perception carries out 407;
406. the base station sends message to the MCBCS server, the type of message is the sensing results report, and sensing results is for existing in the message;
407. if the base station perceives the perception message that the user sends, then carry out 406, otherwise carry out 408;
408. the base station sends message to the MCBCS server, the type of message is the sensing results report, and sensing results is not for existing in the message;
The action behavior of MCBCS server end (referring to Fig. 5).
If whether certain sub-district exists MBS user in the MBS zone 501. the MCBCS server is wanted to understand, then the MCBCS server sends sensing request message to the base station of this sub-district;
502.MCBCS server receives the sensing results report message that send the base station, if sensing results is for existing in the message, then illustrating in the sub-district at this place, base station has MBS user, otherwise the sub-district at this place, base station does not have MBS user;
503.MCBCS sending MBS data or MCBCS to the base station that does not originally belong to the MBS zone stops to send the MBS data to the base station that originally belongs to the MBS zone.
