Description

Cluster transmission notification and processing method and device
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for notifying and processing a cluster transmission.
Background
The trunking communication system communicates in a half-duplex mode, and controls the acquisition and release of channels by Push To Talk (PTT) keys during working, so that the channel utilization rate is high, and the call connection is fast; the users in the group share the downlink channel, and the resource utilization rate is high. Moreover, the trunking communication system can ensure the privacy and the safety of the conversation through voice encryption; preferentially distributing channels for high-priority users or services; communication in an emergency state is ensured through a fail-soft function; and the flexible multi-level grouping scheduling command function is realized through dynamic recombination.
At present, the trunking communication system is developed to a broadband trunking communication system stage, and the leap of various functions and technologies of the trunking communication system can be realized by relying on the most advanced wireless transmission technology, such as the LTE technology. The broadband trunking communication system has the characteristics of supporting diversified service types, diversified transmission modes, large bandwidth and high transmission rate. The supported services include voice, data, video, etc.; the transmission modes comprise unicast, group calling, multicast and the like, wherein the unicast mode works in a full-duplex mode, and the group calling and the multicast mode work in a half-duplex mode.
The performance characteristics of the broadband trunking communication system are as follows: the network reliability is high, and the strong fault weakening and anti-damage capability are realized; the method supports the large traffic capacity of large hot spot areas and hot spot periods; the call setup time is short, and the single system call setup time is less than 500 milliseconds (ms); the network security is high, and end-to-end encryption is supported; wide coverage and low cost for network establishment. Among them, call setup time, network reliability and security are the most important three technical indicators.
In group calling and multicast transmission, because the base station sends the same data to a group of users on the same resource, the channel characteristics of each user relative to the base station are different, the base station can only adopt larger power to send cluster transmission omnidirectionally to meet the requirements of all users in the group. The problem with this is that the interference to co-frequency neighbor cells is large.
In addition, the group call and multicast data sent by the users of a group are insensitive to channel variation, the dynamic scheduling gain is not large, the resources for bearing scheduling signaling are consumed, and a relatively static resource allocation mode is more reasonable.
In a group communication system, one UE may belong to multiple groups, but may only participate in data transmission within one group at a time. The trunking transmission adopts a half-duplex mode, and the speaking right party UE transmits data, that is, when performing uplink transmission, the called UE can only be in a receiving state, that is, only can receive downlink data but cannot transmit uplink data. In addition, the trunking transmission also has the characteristic that only one service exists in one group at the same time, and multiple services are not multiplexed, wherein the service refers to a specific service form, such as voice, video and the like.
From the network side, there may be transmissions of multiple groups simultaneously, each group having a particular member UE participating in group service transmission and reception. There can only be one calling party and several called parties in a group at the same time.
The following channels are introduced in the trunking system:
logical channel:
T-MCCH: trunk Multicast Control Channel, Trunking Multicast Control Channel. And transmitting the trunking multicast control information, including T-MTCH scheduling information, service information, group information and the like. One T-MCCH carries control information or scheduling information for a plurality of groups. A T-MCCH can only correspond to a Multicast Single Frequency Network (MBSFN) area.
T-MTCH: trunking Multicast Traffic Channel. And cluster service data is transmitted, and one T-MTCH only carries data carried by one service.
Transmission channel:
T-MCH: trunking Multicast Channel, Trunking Multicast Channel. The broadcast cluster transmits control information and data.
Physical channel:
PTMCH: physical Trunking Multicast Channel, Physical Trunking Multicast Channel. The bearer cluster transmits signaling and data.
The mapping relationship of the above channels is shown in fig. 1.
The cluster transmission adopts the rule shown in fig. 2:
pre-configuring a T-MCCH resource period and a subframe position, and carrying out actual T-MCCH transmission on a predefined resource position;
the T-MCCH comprises control information of one or more groups and configuration and scheduling information of the T-MTCH;
the transmission of the T-MTCH is carried out based on the scheduling of the T-MCCH and other scheduling commands;
the actual transmission of the T-MCCH may be indicated by a Physical Downlink Control Channel (PDCCH) scheduling command;
the T-MCCH can be retransmitted periodically, and the retransmission can also be scheduled by the PDCCH.
Because the UE belongs to different groups, only the information of the group is concerned, and if all the T-MCCHs are read, the power consumption of the UE is greatly increased. The notification mechanism in the LTE MBMS technology is used to notify the change of the MCCH corresponding to an MBSFN area, and the period is long, which is not suitable for the trunking transmission system.
In summary, if not limited, the UE receives and reads the T-MCCH at each predefined resource location of the T-MCCH. The T-MCCH is mapped to the T-MCH and then mapped to the PTMCH, and organized into a Media Access Control (MAC) Packet Data Unit (PDU) for transmission. The cost for the UE to read the T-MCCH is high, so that the power consumption of the UE is increased, and the power consumption problem of the UE is more prominent because the predefined period of the T-MCCH is very small. A notification mechanism in an LTE Multicast and Broadcast Service (MBMS) technology is used to notify a change of an MCCH corresponding to an MBSFN area, and cannot be directly applied to a trunking transmission system.

Specific explanations are given below.
The embodiment of the invention introduces a cluster control channel notification mechanism for notifying the group attribute of the cluster control channel to be transmitted, which specifically comprises the following three points:
the method comprises the steps that firstly, a base station constructs a cluster control channel notification message (notification message for short), wherein each bit corresponds to one or more groups, the corresponding relation between each bit in the notification message and a group identifier of each group is notified to user equipment, and meanwhile, the base station can also indicate the user equipment to notify the position of message sending resources;
secondly, after receiving a cluster control channel sent by a high-level Entity, such as an MBMS Coordination Entity (MCE), a base station informs a user equipment of which group the cluster control channel to be sent belongs by using a notification message;
and thirdly, the user equipment receives the notification message, judges whether the trunking control channel of the group to which the user equipment belongs transmits, receives the trunking control channel if the user equipment belongs, and does not receive the trunking control channel if the user equipment does not transmit the trunking control channel of the group to which the user equipment belongs.
The details about the first point described above are as follows:
before scheduling and transmitting a trunking control channel, a base station needs to notify a user equipment of a corresponding relationship between a notification message sending subframe configuration (that is, a PDCCH scheduling command sending position for scheduling the trunking control channel) and a Downlink Control Information (DCI) bit (bit) and a group identifier, and a notification mode generally adopts System Information, which is convenient for all the user equipment to know, and the System Information may be a System Information Block (SIB) 13.
Notification message transmission subframe configuration: the notification message is sent at a pre-configured resource position, has a pre-configured resource period and a pre-configured subframe position, and is matched with pre-configured resources sent by a cluster control channel T-MCCH, namely a T-MCCH pre-configured resource position is arranged behind each notification message resource position. If the notification message pre-configuration resource and the cluster control channel pre-configuration resource are located in the same subframe, the notification message can be sent on each cluster control channel pre-configuration resource without introducing separate configuration.
To ensure reliable transmission of notification messages, one enhancement is to send the PDCCH carrying the notification message repeatedly and continuously a number of times.
An example of the configuration of the notification message for notifying the user equipment by the base station is as follows:
the MBMS Notification configuration information element (MBMS-Notification configuration information element) is as follows:
wherein,
the corresponding relationship configuration of the sub-frame and the group identifier in the notification message is introduced as follows:
the base station uses a scheduling command PDCCH for scheduling trunking control channel transmission to carry trunking control channel notification messages, the content contained in the PDCCH is referred to as DCI, taking 3GPP LTE DCI 1C format as an example, wherein the information bit number is greater than or equal to 8, and the corresponding relationship between the information bit number and the group identifier is shown in the following table:
in the notification message sent by the base station to the user equipment, the message format of the correspondence between each bit and the group identifier is as follows:
wherein,
the second point is described in detail as follows:
a base station side: and sending a PDCCH scheduling command at the nearest notification subframe sending position before the trunking control channel sending time point, wherein the PDCCH scheduling command is scrambled by using a fixed group Radio Network Temporary Identity (RNTI). And indicating a group corresponding to a subsequent cluster control channel in the scheduling command, wherein if the transmission of the corresponding group exists, the corresponding bit position in the PDCCH is 1, and otherwise, the bit position is 0. And the base station sends the cluster control channel transmission at the cluster control channel predefined resource position after sending the PDCCH dispatching command, and the notification subframe and the T-MCCH predefined subframe can be the same subframe.
The above third point is described in detail as follows:
the user equipment side: reading the PDCCH scrambled by the group RNTI at the resource position of a notification message sending subframe configured by the base station, and if not, indicating that no cluster control channel is transmitted subsequently; if the PDCCH scrambled by the RNTI of the cluster is read, whether the corresponding indication bit of the group is set to be 1 is checked, if so, the subsequent cluster control channel transmission is read, otherwise, the subsequent operation is not carried out.
The first embodiment is as follows:
referring to fig. 5, the notification message configuration and reconfiguration flow includes:
the eNB side:
s301, the eNB sends system information SIB1 to the UE, wherein the system information SIB1 includes the scheduling information of SIB 13.

S303, the eNB sends SIB13 to the UE, SIB13 is used for configuring the sending period and the sending subframe configuration of the notification message, the corresponding relation between the PDCCH bit and the group identifier, and the pre-configured resource and the sending period of the T-MCCH;
s304, the eNB sends a paging message to the UE to inform the system information change;
s305, the eNB sends the updated SIB1 to the UE, wherein the SIB13 scheduling information is carried in the SIB 1;
s306, the eNB sends the updated SIB13 to the UE, where the SIB13 carries notification message reconfiguration information, and the reconfiguration content may be the position of a notification message sending subframe or the corresponding relationship between a PDCCH bit and a group identifier.
