In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art The every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.

Fig. 1 is the flow chart of the dispatching method for the broadcast resource that one embodiment of the invention provides, and the embodiment of the present invention provides Method be applicable to the implement scene that vehicle in car networking sends broadcast service message, the user equipment in car networking is vehicle The terminal device installed on, such as：Global positioning system (Global Positioning System, GPS), mobile communication Equipment etc..

The executive agent of this method can be a kind of user equipment, specifically comprise the following steps：

Step 101：User equipment sends scheduling request to base station.

In car networking, user equipment sends active safety class service message in a manner of regional broadcast, including vehicle is certainly The status information of body or warning information etc., to notify a certain range of vehicle around it, to avoid dangerous generation. Before sending service message, user equipment needs to send scheduling request to base station by uplink data channels, for asking hair Send broadcast transmission channel (Broadcast Transport Channel, BTCH) subchannel of service message.

Step 102：User equipment receives the detection scheduling channel (Detection in response to scheduling request that base station is sent Scheduling Channel, DSCH) information.

As an alternative embodiment, a dispatching cycle according to a subframe as user equipment, then DSCH information may include：DSCH segment identifications and DSCH competitive resources number.Wherein DSCH segment identifications and DSCH competition moneys The combination of source number corresponds to DSCH resource index values, and DSCH resource index values are for identifying the first DSCH subchannels.

As another optional implementation manner, a tune according to continuous T subframe (T ＞ 1) as user equipment The period is spent, then DSCH information may include：DSCH segment identifications, DSCH competitive resources number and DSCH compete queue length, wherein The combination of DSCH segment identifications, DSCH competitive resources number and DSCH competition queue lengths corresponds to DSCH resource index values, DSCH moneys Source index value is for identifying the first DSCH subchannels.

Step 103：User equipment determines the first DSCH subchannels according to DSCH information.

Specifically, DSCH resource index values, wherein DSCH can be determined according to DSCH information by being had been described in step 102 Resource index value is for identifying the first DSCH subchannels.

Step 104：User equipment detects the first detectable signal in the DSCH resource groups belonging to the first DSCH subchannels.

Specifically, DSCH resources group includes at least one DSCH subchannels, and at least one DSCH subchannels include first DSCH subchannels；It can be seen that the first DSCH subchannels are to belong to a certain DSCH resources group, due to being gone back inside the DSCH resources group There are other DSCH subchannels, and DSCH resources group is corresponding with BTCH resource groups, it is preferred that DSCH resources group is provided with BTCH Source group is one-to-one, can be belonging to the first DSCH subchannels after user equipment determines the first DSCH subchannels A certain BTCH subchannels send service message in the corresponding BTCH resources group of DSCH resource groups, therefore there are different user equipmenies It is possible that the case where same BTCH subchannels can be competed.Optionally, occupied BTCH are carried in the first detectable signal The resource identification of channel；So it is in order to true that user equipment goes the purpose of the first detectable signal of detection inside this DSCH resource group Determine workable BTCH subchannels in BTCH resource groups.Further, the different DCSH letter that the DSCH resources group includes It is the priority of the transmission detectable signal of base station configuration, therefore, user that road, which has the first different priority, first priority, Equipment detects the first detectable signal in the DSCH resource groups belonging to the first DSCH subchannels, specifically includes：User equipment is In DSCH resource groups belonging to one DSCH subchannels, detection priority is higher than in other DSCH subchannels of the first DSCH subchannels Whether there is the first detectable signal.Each DSCH subchannel in DSCH resource groups can wherein be set and correspond to an index value, Wherein index value is smaller, then corresponding DSCH subchannel dispatching priorities are higher, which can be DSCH competitive resources Number, the method for determining the index value are without being limited thereto.

Step 105：User equipment determines the broadcast for sending service message according to the testing result of the first detectable signal Transmission channel BTCH resource groups.

Wherein, BTCH resources group includes at least one BTCH subchannels, and DSCH resources group is corresponding with BTCH resource groups, excellent Choosing, the DSCH resources group is corresponded with the BTCH resources group.

Further, if user equipment does not detect the first detectable signal in DSCH resource groups, it is determined that DSCH is provided BTCH resource groups corresponding to the group of source are for sending the service message；Or,

If user equipment detects that the first detectable signal, user equipment determine the first detectable signal in DSCH resource groups In entrained BTCH subchannels resource identification, and determine the corresponding BTCH letter of resource identification without using BTCH subchannels Road, and determination will other BTCH subchannels including BTCH subchannels be used to send service message in BTCH resource groups.
