Abstract
The invention provides a method for reporting terminal information in a cluster system. The method comprises the following steps: after cluster group calling is established, each non-speaking-right terminal initiates a random access request, and a base station establishes cluster access layer connection with the terminals; the base station actively authorizes the terminals in a cluster access layer connection state in the group calling, and the terminals transmit information to be reported to the base station by using authorized resources after being authorized by the terminal. According to the technical scheme of the invention, null resources can be saved, and the terminal information reporting speed is increased.
Description
Technical field
The present invention relates to wireless communication field, particularly relate to the methods, devices and systems that in a kind of group system, end message reports.
Background technology
In trunked communication system, a colony terminal is only had to have right of speech, remaining set group terminal is in the state of listening to or idle condition, only need down-going synchronous, but obedient party still needs uploaded state information to base station, so that base station is dispatched accordingly according to the channel quality condition of colony terminal, and obedient party is when the application release etc. carrying out right of speech operates, still need to transmit related signaling to base station, so that base station assigns resource.
Based on the feature of above-mentioned trunked communication system, if use existing technology, need to connect for each obedient party sets up wireless heterogeneous networks (RRC), and on uplink physical channel, transmit corresponding information, obviously like this, be not suitable for trunked communication system, because the downlink data of obedient party is all identical, there is no need as each obedient party transmits a identical data, and connect for each obedient party sets up a RRC, power system capacity can be very little.
The random access procedure that existing a kind of solution make use of based on competition completes reporting of obedient party's cluster information.Specific as follows: terminal uses the lead code for colony terminal Stochastic accessing of system configuration to initiate random access request Msg1, base station receives this random access request, according to the type of cluster Stochastic accessing, Msg3 mandate is carried out to this terminal, and by Msg2, Authorization result is informed to terminal; Terminal, according to the Authorization result received in Msg2 and uplink information to be sent, forms Msg3 and sends to network side; Network side receives and resolves Msg3, therefrom obtains the cluster message of terminal to report.
In the above-mentioned methods, in cluster multi call, each terminal has cluster message to need to give the correct time at every turn, all to need after the flow process by MSG1 and MSG2 just by MSG3 its state information report to network side, so just consume a lot of interface-free resources.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of method that in group system, end message reports, and the method comprises: after 1.1 cluster multi calls are set up, and each non-right of speech terminal initiates random access request, and base station and described terminal are set up cluster Access Layer and be connected; Unsolicited Grant is carried out to the terminal being in cluster Access Layer connection status in this cluster multi call in 1.2 base stations, after described terminal receives base station mandate, information to be reported is sent to base station by the resource of use authority, and described information to be reported can comprise the state information and signaling etc. of described terminal.
Further, Unsolicited Grant can issue DCI0 information to realize by giving described terminal; Unsolicited Grant can be periodic, and the described cycle can base station side configure; The described cycle can be determined the performance index requirement of terminal's status information or the combination of the two according to the number of terminals or base station side being in cluster Access Layer connection status in this cluster multi call.
Further, above-mentioned Unsolicited Grant can adopt centralized system to carry out, and discrete way also can be adopted to carry out, such as carry out Unsolicited Grant at same descending sub frame, or carry out at different descending sub frames.
Further, step 1.1 specifically comprises: terminal sends random access request Msg1; Base station receives Msg1, issues Msg2; Terminal receives Msg2, continues to send Msg3; Base station receives Msg3, issues Msg4; Terminal receives Msg4, sends Msg5; Base station receives Msg5, and described terminal is become RRC_Connected state from RRC_Idle state, and is cluster Access Layer connection status (being subordinated to its RRC_Connected state) by described terminal iidentification; Described terminal is in RRC_Connected state at rrc layer, is in Idle state at MME and NAS layer.
The cluster group id information of described terminal can be carried in above-mentioned Msg5; The successful indication information of described terminal Stochastic accessing can be carried in Msg5, but do not comprise the information being delivered to MME and NAS; It is C-RNTI under described terminal is in cluster Access Layer connection status that base station issues C-RNTI that Msg4 distributes; { C-RNTI } of base station side to each terminal distribution being in cluster Access Layer connection status is subordinated to the G-RNTI of this cluster group.
The present invention also proposes a kind of base station, this base station comprises described colony terminal Stochastic accessing processing module for after group calling is set up, receive the random access request that non-right of speech colony terminal is initiated, set up cluster Access Layer for described terminal to connect, described terminal is become RRC_Connected state from RRC_Idle state, be cluster Access Layer connection status by described terminal iidentification, described cluster Access Layer connection status is subordinated to its RRC_Connected state simultaneously; Make described terminal be in RRC_Connected state at rrc layer, be in Idle state at MME and NAS layer; Described cluster operation authorization module is used for carrying out Unsolicited Grant to the terminal being in cluster Access Layer connection status.
Further, described base station can also comprise periodic maintenance module, for determining the cycle of Unsolicited Grant according to the number of terminals and/or the performance index requirement of base station side to terminal's status information that are in cluster Access Layer connection status in cluster multi call.
Further, described base station can also comprise cluster RNTI maintenance module, described cluster RNTI maintenance module, for being in the mapping relations of { C-RNTI } of the terminal of cluster Access Layer connection status under safeguarding each cluster group G-RNT and each cluster group, makes that { C-RNTI} is subordinated to G-RNTI.
The present invention also proposes a kind of terminal, and this terminal comprises: the first module, and for after cluster multi call is set up, initiate random access request, set up cluster Access Layer with base station and be connected, terminal is in connection status at rrc layer, is in Idle state at MME and NAS layer; Second module, for receiving and resolving the Unsolicited Grant information that base station issues, determines authorization resources; 3rd module, information to be reported is sent to base station by the resource for use authority.
The present invention also proposes the system that in a kind of group system, end message reports, and this system comprises base station as above, and terminal as above.
The end message report method of group system that the present invention proposes, base station, terminal and system are that non-right of speech terminal sets up cluster Access Layer connection status by Msg1/2/3/4/5 flow process, instead of the process of the Msg1/2 of the carrying out that each terminal all needs in reporting at every turn in prior art, thus save a large amount of interface-free resources; In the present invention, when terminal establishes once after establishing the connection of cluster Access Layer, Unsolicited Grant will be carried out in base station, and the direct use authority resource of terminal carries out information reporting, so just, make terminal to report more timely to the information of network side, greatly improve the state feedback speed of each colony terminal.
