Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
Applicants studied the current B-Trunc standard and found that: in the current B-TrunC standard, one terminal or dispatch station sends a short message to another terminal or dispatch station, and a receiver needs to immediately reply an acknowledgement message to a sender after receiving the short message. In addition, in practical use, besides the traditional keyboard-operated mobile phone, a large-screen mobile phone is usually provided in the private network cluster terminal (the short data operation interface of the large-screen mobile phone can simultaneously display many pieces of unread information). After the operator clicks, the reading confirmation messages are sent to the sender one by one aiming at all unread short messages, so that the sender receives a large number of reading confirmation messages at a time in a short time, and the risk of message loss exists.
The applicant has studied and found that the possible scenarios with the above problems are as follows:
the first step is as follows: the method comprises the steps that a terminal A sends short messages to a large-screen terminal B, and the terminal A is supposed to send N (N is a positive integer larger than one) short messages totally, and the large-screen terminal B does not read the short messages all the time; the second step is that: an operator clicks a current screen of a large-screen terminal B to check short messages, all N short messages are displayed immediately, and meanwhile, reading confirmation messages are simultaneously replied to a sender terminal A one by one aiming at the N short messages, namely the N reading confirmation messages are required to be replied to the sender terminal A; the third step: if the terminal a is in the idle state, the MME needs to cache all the read acknowledgement messages sent to the terminal a first, and the MME can only issue the read acknowledgement messages after successfully paging the terminal a to the connected state, which may have the following problems:
(1) the single user cannot completely cache the N reading confirmation messages, so that part of the reading receipt is discarded;
(2) the Transaction identifier (Transaction identifier) in the B-Trunc standard is only 4 bits, and if the other side sends more than 16 short messages and the receiving side (large-screen terminal) does not read the scene, the sending side cannot be ensured to accurately confirm that the receiving side has read all the short messages;
(3) and simultaneously transmitting a plurality of NAS messages to increase the air interface overhead and aggravate the network load.
The applicant found that: aiming at the technical problem that a plurality of reading confirmation messages are simultaneously sent between the same pair of users in the prior art, which is difficult to accurately ensure a reading confirmation mechanism, a processing mode of 'message combination' can be carried out on the plurality of reading confirmation messages simultaneously sent between the same pair of users, so that the accurate and reliable transmission of the reading confirmation can be realized, and the air interface overhead and the network load can be reduced.
Fig. 1 is a flowchart of a peer-to-peer short message reading confirmation method for broadband trunking communication according to an embodiment of the present invention.
As shown in fig. 1, the method includes:
step 101: when a receiving terminal receives a plurality of short messages sent by the same sending terminal and detects a reading short message event, generating a uniform reading confirmation message of the plurality of short messages, wherein the uniform reading confirmation message comprises a receiving flag bit for indicating uniform reading confirmation.
Here, the display interface of the receiving side terminal may simultaneously display a plurality of short messages. When a receiving terminal receives a plurality of SHORT messages sent by the same sending terminal and detects a reading SHORT message event (for example, the operation of clicking a display interface triggered by a user on the receiving terminal), a uniform reading confirmation message (SHORT-MSG-RECEIPT) of the plurality of SHORT messages is generated, wherein the uniform reading confirmation message comprises a receiving flag bit for indicating the uniform reading confirmation.
Step 102: and sending the uniform reading confirmation message to the terminal of the sending party through the broadband trunking communication core network.
Step 103: and when the sending terminal detects the receiving flag bit from the uniform reading confirmation message, setting the plurality of short messages into a reading confirmation state.
It can be seen that, in the embodiment of the present invention, the reading confirmation messages are not sent one by one for all unread short messages, but when multiple short messages sent by the same sender terminal are received and a reading short message event is detected, a unified reading confirmation message for the multiple short messages is generated, so that only the single unified reading confirmation message needs to be sent, and the air interface overhead and the network load can be reduced.
In one embodiment, the unified reading confirmation message further includes a transaction identifier in a short message which is newly received by the receiving terminal in the plurality of short messages;
the step 103 of setting the plurality of short messages to the reading confirmation state by the sender terminal includes: the terminal of the sender determines the short message corresponding to the transaction identifier as a critical read short message; and setting the critical read short message and the short messages which are sent to the receiving terminal before the critical read short message is sent and are not set to the reading confirmation state in the plurality of short messages as the reading confirmation state.
In one embodiment, the unified reading confirmation message further includes a Protocol Data Unit (PDU) type cell, a Calling party (Calling party) cell, a Called party cell (Called party), and a Time stamp (Time stamp) cell. Filling a number corresponding to a Called party in a SHORT message (in a SHORT-MSG) in a calling party cell; filling a number corresponding to the Calling party in the SHORT-MSG in the called party cell; the time stamp cell fills in the read time of the short message; receiving the reading confirmation marks of all short messages filled in by the zone bit cells; wherein the receiving the flag bit cell is optional. When the reception flag cell is not set, the message structure of the uniform read confirm message is the same as that of the read confirm message in the prior art.
Table 1 is a message structure table of the unified reading confirmation message.
It can be seen that compared with the reading confirmation message in the prior art, the unified reading confirmation message in the embodiment of the present invention has at least the following improvements:
(1) the receiving flag bit is newly added in the unified reading confirmation message of the embodiment of the invention and is used for indicating the sender to execute the unified reading confirmation.
(2) The transaction identifier in the unified reading confirmation message is set as a transaction identifier in a short message which is received by the receiving terminal from the same sending terminal and is received by the receiving terminal latest, so that the sending terminal is indicated to use the short message of the transaction identifier as a critical read short message, and the critical read short message and the short message which is sent to the receiving terminal before the critical read short message is sent in the plurality of short messages are set as a reading confirmation state. Therefore, when the sender sends a new message and receives the reading receipt intersection, the sender can accurately identify the range of the read message.
Therefore, in the unified reading confirmation message of the embodiment of the invention, the selectable cell Recipt Flag is added, and the terminal of the receiving party simultaneously sends scenes aiming at a plurality of reading confirmation messages and sets the Flag bit to be effective; therefore, only one reading confirmation message needs to be sent, and the reading confirmation messages of a plurality of unread short messages can be borne. And the transaction identifier value is the transaction identifier value of the latest received short message at the moment of sending and reading, so that the sender can accurately identify the read message range when the sender sends a new message and receives and reads the receipt in an intersecting manner. After receiving the uniform reading confirmation message of the sender terminal, the cluster core network sends the uniform reading confirmation message to the receiver terminal through a downlink NAS message; even if the receiving terminal is in an idle state at this time, the MME can also cache and issue the paging to the receiving terminal after the paging is successfully carried out to the connected state, so that the reliable transmission of the message is ensured.
In one embodiment, the sender terminal is a first user terminal or a first scheduler, and the receiver terminal is a second scheduler or a second user terminal.
For example, a short message may be sent from the first user terminal to the second scheduling station or the second user terminal, or the first scheduling station may send a short message to the second scheduling station or the second user terminal.
Fig. 2 is an exemplary flowchart of a peer-to-peer short message reading confirmation method for broadband trunking communication according to an embodiment of the present invention. In fig. 2, an embodiment of the present invention will be described by taking an uplink user terminal (MO UE) to a downlink user terminal (MT UE) as an example.
Wherein:
step 1 to step 2: a sending ue (mo ue) sends a TRUNKING UPLINK TRANSPORT (trunk TRANSPORT) Message to a TRUNKING core network, where a Message Container Type of the Message indicates "SHORT data and status data", the Message Container carries a SHORT Message (SHORT-MSG), and carries a Calling party (Calling party) and a Called party (Called party), where the Mode is 00h (ptp).
Step 5 to step 6: and the receiving UE sends a cluster uplink transmission Message to the cluster core network, wherein the Message Container Type of the Message is indicated as 'SHORT data and state data', and the Message Container carries a SHORT Message acknowledgement (SHORT-MSG-ACK) Message.
When the sending UE sends a plurality of short messages to the receiving UE, steps 1 to 8 are executed a plurality of times, so that the receiving UE will receive the plurality of short messages.
Step 9 to step 10: after the receiving UE is read, the receiving UE sends a cluster uplink transmission Message to a cluster core network, the Message Container Type of the Message is indicated as 'SHORT data and state data', the Message Container carries a uniform reading confirmation Message (SHORT-MSG-RECEIPT), and the uniform reading confirmation Message comprises a receiving flag bit for indicating uniform reading confirmation and a transaction identifier in a SHORT Message which is received by the receiving UE and is received by the receiving UE most recently by a receiving party terminal.
Therefore, the embodiment of the invention combines N pieces of reading confirmation SHORT-MSG-RECEIPT messages which need to be sent simultaneously in the prior art into one message which is sent to the cluster core network, and the flag bit is newly added in the single message to represent the reading confirmation of all unread SHORT messages. And the cluster core network receives the single reading confirmation message and then forwards the single reading confirmation message to the sender terminal, and the sender terminal can confirm all short message reading confirmation according to the single reading confirmation message.
Based on the above description, the embodiment of the present invention further provides a peer-to-peer short message reading confirmation system for broadband trunking communication.
