Description
Technical field
The present invention relates to the communications field, relate more specifically to restatement adjusting device one number time and method under a kind of PTM of being used for bearing mode.
Background technology
Multimedia broadcast-multicast service MBMS is a kind of shared network resource transmits data to a plurality of targets from a data source a technology.The main feature of this technology is: from broadcast multicast service center (Broadcast Multicast Service Centre, be called for short BMSC) to webmaster GPRS Support Node (Gateway GPRS Support Node, be called for short GGSN), (Serving GPRS Support Node from GGSN to the Serving GPRS Support Node, be called for short SGSN), (Radio Network Controller from SGSN to the radio network controller, be called for short RNC) or base station controller (Base Station Controller, be called for short BSC), all adopt the sending mode that a little arrives multiple spot, between two network elements, only set up a cover service bearer at a MBMS business, thereby form a service bearer distribution tree from top to bottom, all subscriber equipmenies (User Equipment under each network element of carrying distribution tree, be called for short UE) all share this network element with the service bearer between the network element contact of its upstream, thereby realize that bearing resource is only professional relevant with MBMS, and irrelevant with the UE number of this MBMS business of use.The 3rd generation partner project (Third Generation Partnership Project, abbreviation 3GPP) MBMS of definition supports two kinds of transmission modes in UTRAN: point-to-multipoint (Point to Multipoint, be called for short PTM) and point-to-point (Point to Point, be called for short PTP), require RNC to take best transmission mode to save ground resource and Radio Resource simultaneously according to the UE quantity that actual needs in the sub-district receives the MBMS business.When having only a spot of UE need receive the MBMS business in the sub-district, adopt the PTP sending mode to set up special-purpose carrying and more save resource at each UE, when having a large amount of UE need receive the MBMS business in the sub-district, then adopt the PTM sending mode to set up the shared common carrier of all UE and more save resource.
When the sub-district sends the MBMS business with the PTM pattern, consider that the UE that has in the sub-district may no longer receive this MBMS business, perhaps owing to shifted out scenes such as sub-district, the UE number that in fact receives the MBMS business in the sub-district is dynamic change.In order to use Radio Resource effectively, RNC is necessary constantly to count again at the UE number that receives the MBMS business in the sub-district, judge according to the result of counting again whether needs switch to the PTP transmission mode or stop sending mode for the PTM pattern of current employing in the sub-district, thereby guarantee in the sub-district, to take best transmission mode to save resource.3GPP points out that UTRAN can take certain business game decision whether to count again according to actual conditions, but concrete restatement is counted strategy, does not mention in the agreement.
