Description
PROCEDURE FOR TRANSMISSION OF LINKING INFORMATION
TRUNK. AND CORRESPONDING TERMINAL AND ACCESS NODE OF
TRONCAL LINKING
FIELD OF THE INVENTION
The present invention relates to a technology for transmitting information and, in particular, to a procedure for transmitting trunk-link information to a corresponding trunk-linking terminal and to an access node.
BACKGROUND OF THE INVENTION
The trunk link communication system is a dedicated trunk communication wireless communication system, which is developed to meet the requirements of industrial users on command and dispatch, and is aimed at particular industrial applications. A certain number of wireless users in the system share a few wireless channels, and command and dispatch are used as primary applications. The trunk link communication system is a multi-purpose, highly efficient wireless trunk communication system.
A group call session is a primary service performed in the trunk link communication system. One feature of the group call session is that multiple terminal users can join the same session connection. A certain user among these users has the right to speak, and belongs to the users with the right to speak. Other users do not have the right to speak, and belong to users without the right to speak. The user with the right to speak transfers data from the group call service (which can include many types, such as voice, files, photographs, images) from a terminal to a network, and then the group call service data is transmitted through from a network, in the form of dissemination, to other users without the right to speak, in order to achieve unified command, dispatch and management of trunk link services.
Taking as an example a broadband trunk link communication system, based on a Long Term Evolution (LTE) technology, in the process of performing trunk link services, a trunk link terminal in a quiescent state, and without the right to speak, you need to refer backbone link state information to an access node, such as an Evolved NodeB (eNB), or you need to transmit Signaling from the No Access (ÑAS) Stratum backbone to a Dispatch Service System (DSS). However, since no Radio Resource Control (RRC) carriers are established between the terminal and the eNB, the above information can not be transmitted.
In order to solve the problem, a current procedure is to establish a dedicated channel for transmitting the trunk link state information and the signaling of the trunk link ÑAS. However, it needs to occupy a lot of resources and the transmission speed is also limited.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described in detail below, in conjunction with the accompanying drawings. It should be illustrated that, without conflict, the embodiments in the present application and features in the embodiments could be combined with each other at random.
Realization one
The present embodiment is described as an example of a broadband trunk link communication system, based on a Long Term Evolution (LTE) technology, where the access node is an eNB, as an example. With reference to the signaling flow illustrated in FIG. 1, the method for transmitting backbone information, according to the present embodiment, includes the following steps.
In step 10, a trunk link terminal (UE) in an idle state, and without the right to speak in the trunk link communication system, initiates random access, and transmits a first message using a terminal access facility trunk link;
the access resource of the trunk link terminal is a resource dedicated to the trunk link terminal which is divided among the resources used during a random access of the terminal of the LTE system, and may take any of the following three forms.
Form one is a form of code domain processing, and the resource dedicated to the trunk binding terminal is a code resource;
in this way, a part of the code resource used to access the LTE terminal, that is, a Preamble of the Random Access Physical Channel (PRACH), is obtained by division, to be dedicated to the random access of the trunk link terminal, and it is indicated as the set A, and other PRACH Preambles are used for the normal access of the LTE terminal. In step 10, the trunk link terminal uses the PRACH Preamble in set A for random access, and transmits the first message (MSG1) to the eNB.
Form two is a form of time domain processing, and the resource dedicated to the trunk binding terminal is a resource of the domain of the
weather;
in this way, a part of the time domain resource, used for accessing the LTE terminal, such as a transmission sub-frame of the PRACH, is obtained by division, to be dedicated to the random access of the trunk binding terminal, and it is indicated as the set A, and other transmission sub-frames of the PRACH are used for the normal access of the LTE terminal. In step 10, the trunk link terminal uses the transmission sub-frame of the PRACH in set A for random access, and transmits the MSG1 to the eNB.
Form three is a combination of the form of the code domain and the form of the time domain, and the resource dedicated to the trunk binding terminal is a combination of code resources and time domain resources;
in this way, a part of the PRACH Preambles, used to access the LTE terminal, is obtained by division, to be dedicated to the random access of the trunk binding terminal, and is indicated as the set A, and a part of the PRACH transmission subframes, used for the LTE terminal access, is obtained by division, to be dedicated to the random access of the trunk link terminal at the same time, and is indicated as the set B. In step 10, the trunk binding terminal uses a PRACH Preamble in set A and a transmission sub-frame of PRACH in set B for random access, and transmits MSG1 to eNB.
The previous access resource of the trunk link terminal can be notified by the eNB to the trunk link terminal, by means of a broadcast message, or it can also be designated in the agreement.
In step 12, after an eNB receives the first message, the eNB determines that a resource used by the first message is the access resource of the trunk binding terminal, and authorizes a time and frequency resource, used by a third message, in a second message returned to the trunk binding terminal.
If form one is used, the eNB performs the detection in the full range of Preambles, determines that the detected PRACH Preambles belong to set A, and authorizes the transmission of a third message (MSG3) in a response, ie a second message (MSG2), returned to the trunk binding terminal.
If form two is used, the eNB performs the detection in the full range of transmission subframes of the PRACH, determines that the detected transmission subframes of the PRACH belong to the set A, and authorizes the transmission of a third message (MSG3) in a response, that is, a second message (MSG2), returned to the trunk binding terminal.
If form three is used, the eNB performs the detection in the full range of Preambles, determines that the detected PRACH Preambles belong to set A and that the transmission subframes of PRACH belong to set B, and authorizes the transmission of a third message (MSG3) in a response, that is, a second message (MSG2), returned to the trunk binding terminal.
In step 14, after the trunk link terminal receives the second message, the trunk link terminal transmits the third message to the eNB, and carries trunk link information in the third message, by signaling the common link control channel upward.
In the present step, the trunk binding terminal may carry the trunk link status information in the third message (MSG3), using the extended signaling of the Uplink Common Control Channel (UL CCCH), or new signaling. After receiving the MSG3, the eNB processes the trunk link status information carried therein.
As an example, the previous flow can be performed in the following scenario: when a trunk binding terminal in a resting state, and without the right to speak (user called trunk link), performs a transfer or requests a neighboring cellular wireless resource, and needs to refer information such as the Reference Signal Received Power (RSRP), or the Quality Received Reference Signal (RSRQ), or the Block Error Rate (BLER), etc., to the eNB, the trunk binding terminal initiates the previous random access flow, and carries the status information necessary to refer to the UL CCCH signaling for its transmission to the eNB;
when the trunk binding terminal in the idle state, and without the right to speak, needs to refer information such as a Trunk Binding Group Identifier where it is located, a call indication of the current group,
or individual call, or group call, and an indication of individual call status, etc., to the eNB, the trunk link terminal initiates the previous random access stream, and carries the status information necessary to be informed in the UL CCCH signaling, for transmission to the eNB; Y
when the trunk binding terminal in the idle state, and without the right to speak, needs to refer the CQI information to the eNB, the trunk binding terminal initiates the previous random access flow, and carries the status information necessary to be informed in UL CCCH signaling, for transmission to the eNB.
Correspondingly, as shown in Fig. 2a, the present embodiment further provides a trunk link terminal based on a LTE technology, comprising:
a random access module 20, configured to initiate a random access when the trunk linking terminal has no right to speak and is in an idle state, and transmit a first message using an access resource of the trunk linking terminal; wherein the access resource of the trunk binding terminal is a code resource, or a time domain resource, or a combination of the code resource and the time domain resource, dedicated to the trunk binding terminal which is divided into the resources used during a random access of the terminal of the LTE system. The specific form of resource processing may be known with reference to the description in step 10.
An information loading module 22, configured to transmit a third message to the access node, and carry trunk linking information in the third message, by signaling the common uplink control channel, when a time and frequency resource, used by the third message, it is authorized in a second message returned by the access node.
Correspondingly, as shown in Fig. 2b, the present embodiment further provides an access node of the LTE system, such as an eNB, comprising a random access processing module, which includes: a first module 30 of reception, configured to receive a first message
transmitted when a terminal initiates a random access;
a response module 32, configured to determine whether a resource used by the first message is or is not the access resource of the trunk binding terminal, and if it is, authorize a time and frequency resource, used by a third message, in a second message returned to the terminal, where the access resource of the trunk binding terminal is a code resource, or a time domain resource, or a combination of the code resource and the time domain resource, dedicated to the terminal trunk link that is divided among the resources used during a random access of the terminal of the LTE system. The processes of the response module, under different forms of resource processing, may be known with reference to the description after step 12.
A second receiving module 34, configured to receive trunk link information carried in the third message by the terminal, by signaling the common channel, and to process the trunk link state information.
Preferably, the access node further comprises a broadcast module, configured to notify the trunk link terminal on the access resource of the trunk link terminal, by means of a broadcast message.
Realization two
The present embodiment is basically the same as embodiment one, as shown in Fig. 3, and the difference between them is that, in step 14, the trunk link information carried by the trunk link terminal in the MSG3, by signaling the common link control channel ascending, it is signaling of the trunk linking ÑAS, such as a right to request a chat, a right to take a talk, a message requesting the establishment of a transmission group, etc., and after step 14, it is also included the next stage.h.
In step 16, after the eNB receives the MSG3, the eNB transparently transmits the signaling of the trunk link ÑAS, carried therein to a DSS for processing.
As an example, the previous flow can be performed in the following scenario: when a trunk terminal in a state of rest, and without right to speak, needs to request a right to speak to the DSS, or to take a talk, the terminal of trunk linking initiates the previous random access flow, and carries the corresponding signaling of the trunk binding ÑAS in the UL CCCH signaling, for transmission to the eNB, and the eNB transparently transmits the signaling of the trunk binding ÑAS to the DSS, for processing.
When the trunk binding terminal, in the idle state and without the right to speak, needs to initiate a group establishment request to the DSS, the trunk binding terminal initiates the previous random access flow, and carries the corresponding signaling of the ÑAS of trunk binding in the signaling of the UL CCCH, for its transmission to the eNB, and the eNB transparently transmits the signaling of the trunk binding ÑAS to the DSS, for processing.
The trunk link terminal and the access node, based on the LTE technology, which are provided in the present embodiment are basically the same as those of the one embodiment, and the modules thereof are also shown in Figs. 2a and 2b, except that the trunk link information carried in the MSG3 by the information loading module 22 in the trunk link terminal, by signaling the common uplink control channel, is the signaling of the trunk binding ÑAS . After the second reception module 32 in the access node receives signaling from the trunk link ÑAS, carried in the third message by the terminal, by signaling the common control channel, the second reception module 32 transmits in a transparent signaling of the trunk link to the DSS, for processing.
A person skilled in the art can understand that all, or a part of, the steps in the above procedure can be implemented by programs that instruct the related hardware, and the programs can be stored in a computer-readable storage medium, such as a read-only memory, a disk, etc. Alternatively, all, or a part of, the stages in the
Previous embodiments may also be implemented by one or more integrated circuits. Accordingly, each module / unit in the above embodiments can be implemented in the form of hardware, or it can also be implemented in the form of software functional module. The present invention is not limited to any particular form of a combination of hardware and software.
The above description is only of preferred embodiments of the present invention, and is not intended to limit the present invention. Those skilled in the prior art can make various modifications and variations in the present invention. Any modification, equivalent substitution and improvement made within the spirit and the principle of the present invention should be included within the scope of protection of the present invention.
