An example of a group context according to an embodiment of the present invention is shown in table 1. Various information is given as an example for convenience of description, and information may be defined in different ways in different embodiments.
303, after the MTC ue is powered on, the access is initiated according to a mode of a general ue, a preamble is sent, and after a TA (Timing Advance, sending Timing Advance) is obtained, an RRC connection request (RRCConnectionRequest) message is sent, where the message may carry an MTC identifier (MTC indicator) indicating a classification of the MTC ue.
305, after receiving the request, the base station acquires the MTC identifier and feeds back an RRC connection setup (RRCConnectionSetup) message, where the RRC connection setup message requests the MTC ue to perform full-band uplink channel quality sounding (sounding).
307, after receiving the RRC connection setup message, the MTC ue feeds back an RRC connection setup complete (RRCConnectionSetupComplete) message, where the message carries a full-band uplink channel quality Sounding signal (Sounding RS).
309, after receiving the RRC connection setup complete message, the base station allocates an intra-group sequence number to the UE based on the full-band uplink channel quality probing signal, and updates the updated sequence number and the resource allocation information table in the group context, where the flag bit of successful transmission is set to be false, for example, see table 2.

TABLE 4
If the number of times of group continuous paging is 3, the group initial access time offset is set to 3 for the first group paging, 2 for the second time, and 1 for the third time. Therefore, the MTC user equipment can know that the received group call message is the fourth time, and the time of uploading the initiated access time is consistent with the time required by the group call message through calculation.
321, the MTC UE wakes up at the time of receiving the group call message to receive the group call message, if the group call message is detected, determines whether a group ID in the group call message is the same as a group ID in the stored group call parameter, and if the group ID in the group call message is the same as the group ID in the stored group call parameter, calculates an access initiation time according to resource configurations such as a sequence ID (sequence ID), an exclusive radio bearer serial number, exclusive RB parameter information, an exclusive time window length, and the like:
(sequence id-1) x length of dedicated time window at the time of initiating access
323, the MTC ue sends the dedicated preamble using the dedicated preamble configured in the group call parameter at the time of initiating access.
The dedicated preamble sending mode may continuously send the dedicated preamble in a unit TTI, and sequentially ramp up the primary (step) power, so as to facilitate network detection, until an RAR (Random Access Response) message carrying synchronization information is received or the dedicated preamble is ramped up to the maximum sending number of the preamble, and if the RAR is not received even when the maximum sending number of the preamble is reached, the exception handling is performed.
325, after receiving the exclusive lead code sent by the MTC user equipment, the base station feeds back the RAR message carrying the synchronization information and prepares to start receiving data
327, after the MTC ue determines the TA according to the synchronization information, the MTC ue starts to transmit data after a fixed time interval defined in the dedicated RB parameter configuration.
329, when the data transmission is finished or the length of the exclusive time window is up, the MTC user equipment is switched to an idle state again. When the data reporting is completed, the group calling message is monitored continuously.
331, after the base station completes the data reception of a single MTC UE, the transmission success flag bit of the MTC UE is set to true, and the RLC, MAC, and other entities are reset. Thereby being ready for the data reception of the next MTC user equipment.
And after the sending periods of all the MTC user equipment are passed, performing exception handling on the MTC user equipment with transmission failure. And setting the transmission success flag bits of all the MTC user equipment to be false, and ending the reporting process.
The exception handling for the MTC user equipment may be to perform a separate call procedure for a general user equipment.

According to the technical scheme, the embodiment of the invention can carry out initial MCS selection by configuring the quality detection of the full-band uplink channel according to the low mobility of the user equipment, carry out static RB grouping and configure the group context according to the MCS selected by all the user equipment, ensure that the user equipment still stores the group context after being switched into the IDLE state, and combine with sequential access to ensure that the user equipment carries out data transmission according to the static configuration in sequence when receiving the reporting requirement, thereby realizing the configuration and the reconfiguration without RB and the PDCCH dispatching process, greatly saving signaling interaction, and greatly saving the expense compared with the mode of maintaining the group context by the base station.
Further, the transceiver module 51 is further configured to send a message carrying a machine type communication identifier to a base station, so that the ue configures a group context.
The transceiver module 51 is specifically configured to receive the group call message sent by the base station when the group call parameter includes a group ID, an intra-group number, an exclusive time window length, a maximum transmission number of preambles, an exclusive preamble, and exclusive RB parameter information, and calculate an access initiation time of a response of the group call message according to an intra-group signal and the exclusive time window length when a group ID carried by the group call message is the same as the stored group ID; at the access initiating time, according to the maximum transmission times of the lead code, continuously sending the exclusive lead code to the base station at unit transmission time intervals until receiving a message carrying synchronous information or reaching the maximum transmission times of the lead code; and after receiving a message carrying synchronization information sent by the base station according to the received dedicated lead code, sending data to the base station according to the synchronization message and the dedicated RB parameter information.
The transceiver module 51 transmits the dedicated preamble for the first time with the stored power decreased by one step from the power recorded when the message was successfully transmitted last time, and stores the power when the message was successfully transmitted this time.
As shown in fig. 7, further, the apparatus 50 further includes:
and a processing module 53, configured to, after the response is successfully sent or the sending time reaches the length of the dedicated time window, enter an idle state.
