Table.
Step 7: if CN establishes group by Trunking Group Context Setup Request message informing eNB
Business, then the eNB establishes group service according to Trunking Group Context Setup Request message；If CN is logical
It crosses Trunking Group Context modify request message informing eNB and establishes group service in target TA, then should
ENB establishes group service in target TA according to Trunking Group Context modify request message.
Wherein, which establishes group service according to Trunking Group Context Setup Request message,
Specifically include: group service is established in the RAB list that eNB is issued according to core net.
Step 6b: core net sends Trunking paging message to the eNB.
Wherein, group identification, group network temporary identifier G-RNTI are carried in Trunking paging message, optionally,
Group's default resource configuration index can also be carried.
Step 8: the eNB forwards the Trunking paging message to give the UE.
Step 9: if not including cluster default configuration in Trunking paging, which exhales configuration
(Group call config) message.
Wherein, the cluster default configuration, including clustered control channel TCCH group service channel TTCH, cluster voice half
Static SPS configuration, configuration index are 0-15, corresponding different resource configuration parameter.Configuration index is carried in message.
Group Call Config message carries TTCH channel resource and matches confidence for configuring group service channel TTCH
Breath.
