Specify wireless broadcast/multicast system of the present invention below.
Before describing wireless broadcast/multicast system of the present invention; Management area and the coverage that the present invention relates at first is described, as shown in Figure 1, wherein; The management area is divided into three types according to size: global administration territory (GBA), district management territory (ZMBA) and single cell management territory (CMBA).
Global administration territory (GBA) is the scope that overall broadcast multi-broadcasting control centre is managed, the scope that promptly whole broadcast multicast system covered.
District management territory (ZMBA) is the regional extent that regional broadcast multicast control centre is managed, and each district management territory is corresponding one by one with a regional broadcast multicast control centre.District management territory static configuration in whole system, one group of the management of expression regional broadcast multicast control centre base stations neighboring physically.Do not intersect between the district management territory, the scope that all district management territories integrate is exactly the scope in global administration territory.
Single cell management territory (CMBA) is the zone that single base station is managed.A district management territory (ZMBA) comprises one to a plurality of single cell managements territory, does not occur simultaneously between each single cell management territory.
The coverage is divided three classes according to the scope that covers: global service territory (GBS), district's service-domain (ZMBS) and single sub-district service-domain.
Global service territory (GBS) is an overall broadcast service institute region covered, and this zone is corresponding with the global administration territory;
District's service-domain (ZMBS) is as far as a broadcast multi-broadcasting service; In a scope, send the scope that the broadcast multi-broadcasting service is covered; Maybe be in district's service-domain not to some cell transmission service data, to district's service-domain synchronization field of formation for the data of this broadcast multi-broadcasting service of a broadcast multi-broadcasting service.
District's service-domain (ZMBS) and district management territory (ZMBA) be one-to-one relationship not, district's service-domain can less than, be equal to, or greater than the scope in a district management territory.
Has common factor between a plurality of districts service-domain.
A single-frequency network area is meant one group of physically adjacent sub-district, and these sub-districts have been configured some identical frequency resources and have been used for the broadcast multi-broadcasting service.Identical physical layer resources and the setting of MAC layer are used in the broadcast multi-broadcasting service of on a single-frequency network area, transmitting, and the wireless signal of these broadcast multi-broadcasting data of therefore in these sub-districts, sending is identical.District's service-domain can use the subclass of single-frequency network area as it, therefore, possibly comprise one in district's service-domain to a plurality of single-frequency network areas and zero zone to a plurality of single Cell Broadcast CBs.
Single sub-district service-domain is meant the scope that the broadcast multi-broadcasting service of only in a sub-district, sending is covered.The wireless base station sends the broadcast multi-broadcasting data through the mode of putting multiple spot in the service-domain of single sub-district.Single cell service area is to a service, and the coverage of this service is only within an independent sub-district, and single Cell Broadcast CB is meant and uses the mode of broadcasting within a sub-district, to send data.That sub-district of a single cell service area covering uses single Cell Broadcast CB as sending service manner certainly.
Dissimilar service that said different coverage is corresponding, promptly overall broadcast service, regional broadcast multicast service and single Cell Broadcast CB multicast service.
When carrying out the initialization of broadcast multi-broadcasting service, the initialization of serving comprises the global service territory, district's service-domain and the service-domain initialization of single sub-district.
Usually; What the management area was corresponding is physical entity, and promptly where wireless network sets up a base station when setting up; Then the scope of this base station covering is called the scope in single cell management territory; And service-domain corresponding be logic entity, show the scope that a service should cover, this scope is configured by wireless system operation and management mechanism.
Initialization is meant the initialization of service, comprises the global service territory, district's service-domain and the service-domain initialization of single sub-district.
For global service territory and single sub-district service-domain; Its scope is changeless during whole broadcast multicast system operation; Have only the coverage of district's service-domain during the broadcast multi-broadcasting service is sent, the reception condition according to wireless terminal (UE) to change dynamically, its scope can change between the service-domain of single sub-district in the global service territory.

Regional broadcast multicast control centre (ZMBC) 42 is used under the management of overall broadcast multi-broadcasting control centre 41, to the Synchronization Control and the dynamic resource scheduling of the service of the broadcast multi-broadcasting in the one's respective area.When service is trans-regional; The distribution of resource is arranged by overall broadcast multi-broadcasting control centre (GBC) 41 is unified earlier; When service is not trans-regional; Overall situation broadcast multi-broadcasting control centre (GBC) 41 provides general resource allocation condition, is freely distributed in available resource by (ZMBC) 42 of regional broadcast multicast control centre.
Another object of the present invention is to provide a kind of control method of broadcast multi-broadcasting service; Thereby on more excellent degree, make full use of the advantage of SFN (SFN); Through being different services; Resources allocation under suitable situation; Using less Radio Resource through the use SFN pattern of dividing at the regional service intra-zone is that the terminal provides good broadcast multi-broadcasting service more, and overall broadcast service has then all used the SFN pattern to send service data in all sub-districts, thereby this system can provide the favorable service quality to the user; Simultaneously, flexibly dynamic service range changing method is provided, improve system wireless resource utility efficiency and simultaneously in complexity that the reduction system carries out corresponding control on degree.
Describe the control method of broadcast multi-broadcasting service of the present invention below in detail, as shown in Figure 4.Comprise the following steps:
Step S100 when the initialization of carrying out the broadcast multi-broadcasting service distributes, serves initialization.It comprises the global service territory, district's service-domain and the service-domain initialization of single sub-district; When a regional broadcast multicast service is configured to system at first, obtain an initial service coverage according to control command.
This scope has comprised one group of sub-district of estimating to provide this service.If the multicast service, the end message of this service that then also comprised current register in the initial information of this service.
Step S200 according to the control information of broadcast multi-broadcasting service, confirms that this broadcast multi-broadcasting service is overall broadcast multi-broadcasting service, regional broadcast multicast service, still single Cell Broadcast CB multicast service.
These control informations are confirmed by the operation and management mechanism of network, control through when service is initialized, the basic parameter that disposes being sent to core network.
Step S300 according to different broadcast multi-broadcasting services, is that the service cell covered is sent the broadcast multi-broadcasting service data according to the different strategies distributing radio resource and to wireless terminal by broadcast multi-broadcasting control centre control system.
In the methods of the invention, broadcast multi-broadcasting control centre (MBC) to be used for through coming for broadcast multi-broadcasting service dynamic assignment resource be that a broadcast multi-broadcasting service provides more SFN mode cell as much as possible.When broadcast multi-broadcasting gateway (MB-GW) after system sends service announcement information; Overall situation broadcast multi-broadcasting control centre (GBC) receives corresponding signaling; The initial coverage of then should overall situation broadcast multi-broadcasting control centre checking this service; Be the identical Radio Resource of said broadcast multi-broadcasting service assignment on this scope, simultaneously assignment information sent in the corresponding regional broadcast multicast control centre (ZMBC).Regional broadcast multicast control centre disposes the Radio Resource of the respective cell under its management area then, and regional broadcast multicast control centre (ZMBC) feeds back to GBC with assignment information after having assigned.
When said broadcast multi-broadcasting service was served for the regional broadcast multicast, as shown in Figure 5, said step S300 specifically comprised the following steps:
Step S310, when needs sent the broadcast multi-broadcasting service, the overall broadcast multi-broadcasting control centre (GBC) of broadcast multi-broadcasting gateway in broadcast multi-broadcasting control centre sent the resource allocation request signaling, asked overall broadcast multi-broadcasting control centre to be this service assignment resource.
Step S320, overall broadcast multi-broadcasting control centre serves initial cell covered information according to this, confirms to carry the position of the Target cell of this service.

When said broadcast multi-broadcasting service was single Cell Broadcast CB multicast service, said step S300 specifically comprised the following steps:
Step S310 ', if a broadcast multi-broadcasting service is only transmitted in single subdistrict, then broadcast multi-broadcasting gateway (MB-GW) can not send request for allocation to overall broadcast multi-broadcasting control centre (GBC), but directly notifies wireless base station (BS) Service Source request.This process comprises the following steps:
Step S311 ', what the wireless base station was autonomous is this service assignment resource;
Step S312 ', the wireless base station reports to regional broadcast multicast control centre (ZMBC) with allocation result;
Step S313 ', regional broadcast multicast control centre upgrades the resource allocation management information of oneself;
Step S314 ', regional broadcast multicast control centre sends the resource change report to overall broadcast multi-broadcasting control centre.
When said broadcast multi-broadcasting service was the service of overall broadcast multi-broadcasting, said step S300 specifically comprised the following steps:
Step S310 ", the fixing broadcast program data that in global scope, provides uses special-purpose channel resource that overall broadcast service (GMB) is provided by overall broadcast multi-broadcasting control centre (GBC) control.
This overall situation broadcast service is transparent on other broadcast multi-broadcasting zones, and therefore overall broadcast service can not served the competition that (ZMB) produces Radio Resource with other regional broadcast multicast.
In wireless broadcast/multicast system of the present invention, adopt SFN (SNF) technology, through becoming to use identical Radio Resource to carry same broadcast multi-broadcasting service a plurality of physically adjacent cell configuration.Can make wireless terminal (UE) obtain better cell edge service quality like this, guarantee the service continuation of wireless terminal when moving between cells.
Step S400; When a broadcast multi-broadcasting service need be crossed over a plurality of regional broadcast multicast control centre management area; Overall situation broadcast multi-broadcasting control centre will redistribute Radio Resource for this service in district's service-domain, and will send the broadcast multi-broadcasting service data in different broadcast multi-broadcasting zones to wireless terminal.
In the process that the broadcast multi-broadcasting service is sent; According to the dynamic change situation of the residing position of user, the scope that the broadcast multi-broadcasting service covers can be adjusted under the control of overall broadcast multi-broadcasting control centre (GBC) and regional broadcast multicast control centre (ZMBC) dynamically.
When wireless terminal (UE) when the edge of broadcast multi-broadcasting coverage shifts out; Dynamic Resource Allocation for Multimedia carried out in the sub-district that broadcast multi-broadcasting control centre (MBC) will be according to circumstances moves into this wireless terminal, this sub-district included within the coverage of broadcast multi-broadcasting coverage and the cell configuration of this sub-district and inside, broadcast multi-broadcasting coverage is become the SFN pattern.
Similarly; When the edge of wireless terminal (UE) from the broadcast multi-broadcasting coverage moves to the center of broadcast multi-broadcasting coverage; When causing this sub-district to no longer include the user need receiving the service of this broadcast multi-broadcasting, broadcast multi-broadcasting control centre can discharge corresponding radio resource on this sub-district.
Through adopting said radio-resource-configuration; Broadcast multi-broadcasting control centre (MBC) guarantees to carry out the Radio Resource dynamic assignment for the broadcast multi-broadcasting service to the full extent; Can not cause owing to be difficult to constitute the situation of SFN pattern between the uneven sub-district of causing of resource and take place, the RRM of regional service flexibly can be provided and reduce the complexity of system.
