Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, the coverage of a 4G (fourth generation mobile communication technology) network, such as an LTE (Long Term Evolution) network, is relatively perfect, and indoor distribution systems for improving mobile communication signals are generally deployed in indoor environments such as large buildings, underground shopping malls, underground parking lots, and the like, but with the advance of 5G (fifth generation mobile communication technology) network construction, the 5G network puts higher requirements on the coverage of mobile communication signals in the indoor environment, and under the 5G network, the indoor distribution systems may have more slave nodes, so in the field of mobile communication signal improvement of the indoor environment, how to fully utilize the existing indoor distribution systems, reduce the construction and maintenance costs of the 5G network, and improving the coverage of the 5G network in the indoor environment becomes a significant subject. In the problem, how to implement communication timing planning of a master node and a slave node in an indoor distribution system is an urgent problem to be solved.
As shown in fig. 1, the indoor distribution system mainly includes a master node 01 and a plurality of slave nodes 02, where the master node is connected to an information source and transmits a mobile communication signal of the information source to the slave nodes, and the slave nodes process the received mobile communication signal and transmit the processed mobile communication signal to an air interface, thereby completing coverage of the mobile communication signal in an indoor environment.
In an alternative implementation, after the indoor distribution system completes the cell search, its communication status may be as illustrated in fig. 2, including:
the method comprises the following steps that (Init State), after an indoor distribution system is started and network searching is completed, a master node and a slave node enter an initialization State to complete necessary initialization operation;
the method comprises the following steps that a Master Boot State (Master Boot State) is started after initialization of a Master node is completed, and the Master Boot State is mainly used for broadcasting and informing that the Master node is restarted after some restarting operations of the Master node under the condition that a slave node does not know are processed;
waiting for a downlink heartbeat State (Wait DL Heart State), and entering a downlink heartbeat waiting State after the slave node completes initialization so as to Wait for a heartbeat message of the master node;
in the access State (RACH State), a slave node requests to access a master node, and in the State, the embodiment of the present invention can implement handshake between the master node and the slave node;
a Normal working State (Normal State), in which the master node sends a heartbeat message to the slave node and completes a handshake process; after finishing the handshake process in the access state, the slave node enters a normal working state; after the master node and the slave nodes are in normal working states, the indoor distribution system works normally.
From the communication state illustrated in fig. 2, it can be seen that the master node and the slave node have requirements for sending and receiving messages in different communication states, and therefore a set of communication timing planning scheme needs to be designed to determine respective times for sending messages by the master node and the slave node in different communication states.
Based on this, the embodiment of the present invention considers that the hyper frame number is introduced, and the hyper frame number can be used for communication timing planning between the master node and the slave node, that is, the hyper frame number can determine the respective sending time of the message by the master node and the slave node.
In an alternative implementation, fig. 3 shows an alternative signaling flow of the communication timing planning method provided in the embodiment of the present invention, and as shown in fig. 3, the flow may include:
step S10, the master node obtains the master hyper frame number.
In the embodiment of the invention, the hyper frame number can be used for planning the communication time sequence between the master node and the slave node, correspondingly, the master node can determine the message sending time according to the hyper frame number of the master node, and the slave node can determine the message sending time according to the hyper frame number of the slave node. For convenience of explanation, in the embodiments of the present invention, the hyper frame number of the master node is referred to as a master hyper frame number, and the hyper frame number of the slave node is referred to as a slave hyper frame number.
In an alternative implementation, the hyper frame number may be counted in milliseconds as a base unit; in a more specific optional implementation, aiming at a specific mobile communication standard, a communication system comprises a system frame number, and the embodiment of the invention can expand a plurality of bits as the hyper frame number on the basis of the system frame number of the communication system, thereby obtaining the hyper frame number on the basis of the existing system frame number of a multiplexing communication system; in an example, in the 3GPP LTE communication standard, there is a 10-bit system frame number, and the system frame number is counted in 10 milliseconds, and then the embodiment of the present invention may extend multiple bits on the basis of the system frame number based on the system frame number to obtain a hyper frame number, so that the hyper frame number can cover a longer time range, and thus the master node and the slave node may perform communication timing planning within the longer time range.
In an example, in the embodiment of the present invention, a system frame number of 10 bits (i.e., 8-Bit Information is carried in an actual MIB, and a physical layer may determine Information lower than 2 bits during reading the MIB to obtain a system frame number of 10 bits) from an MIB (Master Information Block); because the system frame number of 10 bits is not sufficient for communication timing planning of the indoor distribution system, the embodiment of the invention can expand a plurality of bits on the basis of the system frame number of 10 bits to obtain the hyper frame number (such as obtaining the main hyper frame number of the main node), for example, the embodiment of the invention can expand the information of 6 bits on the basis of the system frame number of 10 bits to obtain the hyper frame number of 16 bits.
Step S11, the main node sends a main handshake message to the slave node according to the first time determined by the main hyper-frame number, wherein the main handshake message at least carries the main hyper-frame number.
Based on the main hyper-frame number of the main node, the embodiment of the invention can determine the time for the main node to send the message to the slave node, and the embodiment of the invention can set the first time determined by the main hyper-frame number and send the message to the slave node by the main node; in an alternative implementation, in order to enable a slave node of an indoor distribution system to access a master node, so as to provide a basis for normal communication between the master node and the slave node, in an embodiment of the present invention, after the master node is initialized, a master handshake message (for convenience of description, a handshake message of the master node may be referred to as a master handshake message) may be initiated from the master node to the slave node, so as to wait for the slave node to request to access the master node. Based on this, optionally, at the first time determined according to the master hyper-frame number, the master node may send a master handshake message for waiting for requesting access to a slave node of the indoor distribution system, where the master handshake message may carry at least the master hyper-frame number, so that the slave node may synchronize the slave hyper-frame numbers of the slave nodes based on the master hyper-frame number, and achieve alignment of the slave hyper-frame numbers of the slave nodes with the master hyper-frame number of the master node.
In a more specific alternative implementation, the master node may periodically broadcast the master handshake message to the slave nodes of the indoor distribution system at a first time determined based on the master superframe number.
Optionally, the main hyper-frame number has information of a plurality of bits, and the main hyper-frame number changes with time, so that on the basis that the main hyper-frame number changes with time, the embodiment of the invention can determine whether the current time is the time for the main node to send the message or not based on the bit information of a certain position of the main hyper-frame number; specifically, the embodiment of the present invention may set bit information of the first position of the master hyper-frame number, and determine whether the current time is the time when the master node sends the message, for example, when the bit information of the first position of the master hyper-frame number is a first value, the embodiment of the present invention may determine that the current time is the time when the master node sends the message, so that the master node may send the master handshake message carrying at least the master hyper-frame number to the slave node when the bit information of the first position of the master hyper-frame number is the first value; for example, the first position may be a lower 5-bit position of the master hyper-frame number, and the first value is, for example, 0x10, so that the master node may transmit a message to the slave node by the master node when the bit information of the lower 5-bit position of the master hyper-frame number is 0x 10.
In an alternative implementation, the order of the high and low of the bit positions of the hyper frame number may be, for example: the bit positions are sequentially lowered in left-to-right order.
And step S12, the slave node receives the master handshake message and synchronizes the slave hyper frame number according to the master hyper frame number.
When the slave node receives the master handshake message, the slave hyper-frame number can be updated based on the master hyper-frame number carried by the master handshake message, so that the hyper-frame number of the master node is synchronized with the hyper-frame number of the slave node (i.e. the master hyper-frame number is synchronized with the slave hyper-frame number), and the master node and the slave node can transmit messages based on the same hyper-frame number and under the same rhythm.
And step S13, the slave node sends a slave handshake message to the master node according to the second time determined by the slave hyper-frame number.
Based on the slave hyper-frame number after the slave node and the master hyper-frame number are synchronized, the embodiment of the invention can determine the time for sending the message from the slave node to the master node. In an alternative implementation, after acquiring the master handshake message, the slave node may send a slave handshake message for requesting access to the master node (for convenience of description, the handshake message sent by the slave node may be referred to as a slave handshake message), and based on this, in an alternative implementation, the slave node may send the slave handshake message for requesting access to the master node according to the second time determined by the slave hyper frame number.
Optionally, in the embodiment of the present invention, it may be configured to set bit information of at least a first position of the slave superframe number, and determine whether the current time is the time for the slave node to send the message, for example, when the bit information of at least the first position of the slave superframe number is a second value, the embodiment of the present invention may determine that the current time is the time for the slave node to send the message, so that the slave node may send a slave handshake message for requesting to access the master node to the master node when the bit information of at least the first position of the slave superframe number is the second value; in an optional implementation, the second value may be smaller than the first value, that is, on the basis of synchronization between the master superframe number and the slave superframe number, the master node sends a message to the slave node when bit information at a first position of the master superframe number is the first value, and the slave node sends a message to the master node when bit information at least the first position of the slave superframe number is the second value; in one example, the first position may be a lower 5-bit position of the hyper-frame number, and the second value is, for example, 0x00, so that the slave node may transmit a message to the master node by the slave node when bit information from at least the lower 5-bit position of the hyper-frame number is 0x 00.
And step S14, the master node receives the slave handshake message and sends a master handshake confirmation message to the slave node at the first time determined according to the master hyper-frame number.
It can be understood that, in a state where the master superframe number changes with time, the first time determined by the master superframe number is set, and the master node sends a message to the slave node, so that the master node can send a master handshake confirmation message to the slave node at the first time determined based on the master superframe number after receiving a slave handshake message sent by the slave node to request access to the master node; optionally, in an example, after receiving the slave handshake message, the master node may send a master handshake confirmation message to the slave node when bit information of a first position of the master superframe number is a first value, for example, the master node may send the master handshake confirmation message to the slave node when bit information of a lower 5-bit position of the master superframe number is 0x 10.
It should be noted that the master handshake confirmation message may indicate that the slave node and the master node have failed to handshake, or may indicate that the slave node and the master node have successfully handshake, which is not limited in the embodiment of the present invention.
Optionally, further, in a case that the slave node and the master node handshake successfully, the slave node accesses the master node, so that the slave node can perform normal communication with the master node, a mechanism is set according to an embodiment of the present invention, in which the master node sends a message to the slave node at a first time determined based on the master superframe number, and the slave node sends a message to the master node at a second time determined based on the slave superframe number, when the slave node and the master node normally communicate, the master node can send a normal communication message to the slave node at the first time determined based on the master superframe number, and the slave node can send a normal communication message to the master node at the second time determined based on the slave superframe number.
In the communication timing sequence planning method provided by the embodiment of the invention, the master node can determine the time for sending the message to the slave node based on the master hyper-frame number, and after the slave hyper-frame number of the slave node is synchronous with the master node, the slave node can determine the time for sending the message to the master node based on the slave hyper-frame number, so that the master node and the slave node can communicate with each other and the time for sending the message can be planned by the hyper-frame number, and the master node and the slave node in the indoor distribution system can better coordinate with each other; the communication time sequence planning scheme of the master node and the slave node provided by the embodiment of the invention is realized based on the hyper frame number, the realization complexity of the communication time sequence planning scheme is lower, and the complexity caused by the traditional communication time sequence planning by central equipment can be reduced.
In a further optional implementation, the embodiment of the present invention may further subdivide the time for sending the non-handshake message and the handshake message by the slave node, taking as an example that the slave node sends the message when the bit information of at least the first position from the hyper-frame number is the second value, and the embodiment of the present invention may further specifically distinguish whether the handshake message is sent by the slave node or the non-handshake message (the non-handshake message is, for example, a normal communication message, etc.); optionally, from the perspective of a node, fig. 4 shows a flow of a communication timing planning method provided by the embodiment of the present invention, and as shown in fig. 4, the flow may include:
and step S20, the slave node sends a slave handshake message to the master node when the bit information of the second position of the slave hyper-frame number is a third value.
The slave node receives the master handshake message, synchronizes the slave hyper-frame number with the master hyper-frame number carried by the master handshake message, and can send the slave handshake message to the master node when the bit information of the second position of the slave hyper-frame number is a third value; alternatively, the third value may be greater than the first and second values.
In a further optional implementation, the bit information from the second position of the hyper-frame number may comprise bit information from the first position of the hyper-frame number, and the bit information from the first position of the hyper-frame number is a second value; for example, the bit information of the second position and the first position may both be the lower position bit information of the secondary superframe number, in one example, the bit information of the second position of the secondary superframe number, for example, the bit information of the lower 6bit position of the secondary superframe number, the bit information of the first position of the secondary superframe number, for example, the bit information of the lower 5 bit position of the secondary superframe number, in a further example, the third value may be 0x20, that is, when the bit information of the lower 6bit position of the secondary superframe number is 0x20, the secondary node may send a secondary handshake confirmation message to the primary node; it is understood that the bit information from the lower 6bit positions of the hyper-frame number is 0x20, and the bit information from the lower 5 bit positions of the hyper-frame number is 0x00, that is, the bit information from the second position of the hyper-frame number may contain the bit information from the first position of the hyper-frame number, and the bit information from the first position of the hyper-frame number is the second value.
And step S21, the slave node sends a non-handshake message to the master node when the bit information of the second position of the slave hyper-frame number is a fourth value.
In the embodiment of the present invention, the slave node may send the non-handshake message to the master node when the bit information at the second position of the slave hyper-frame number is a fourth value, for example, when the slave node accesses the master node and the slave node communicates with the master node normally, the slave node may send the non-handshake message for normal communication to the master node when the bit information at the second position of the slave hyper-frame number is the fourth value. For example, the fourth value may be, for example, 0x00 from the bit information of the second position of the hyper frame number, for example, from the bit information of the lower 6bit position of the hyper frame number.
It can be seen that, in the optional embodiments provided in the embodiments of the present invention, the master node may send a message to the slave node when the bit information of the first position of the master hyper-frame number is a first value, for example, the master node may send a master handshake message, a master handshake acknowledgement message, a message controlling remote restart, and the like to the slave node;
aiming at the slave node, after the slave hyper-frame number of the slave node is synchronous with the master hyper-frame number, the slave node can send a message to the master node when the bit information of at least a first position of the slave hyper-frame number is a second value, and the second value is smaller than the first value;
more specifically, the slave node may send the slave handshake message to the master node when the bit information of the second position of the slave hyper-frame number is a third value, where the bit information of the second position of the slave hyper-frame number may include the bit information of the first position of the slave hyper-frame number, and the bit information of the first position of the slave hyper-frame number is a second value, and the third value may be greater than the first value and the second value; and the slave node may send a non-handshake message to the master node when the bit information of the second position of the slave hyper-frame number is a fourth value, the bit information of the second position of the slave hyper-frame number including the bit information of the first position of the slave hyper-frame number.
The embodiment of the invention aims at the slave node, can further determine the sending time of the handshake message and the non-handshake message of the slave node based on the hyper frame number, and can realize more accurate communication time sequence planning of the slave node.
In a further optional implementation, because the indoor distribution system has a large number of slave nodes, the embodiment of the present invention may further determine the slave node currently sending the message based on the slave superframe number, so that the slave node with the large number in the indoor distribution system can send the message according to the precise timing constraint, avoid that multiple slave nodes send the message to the master node at the same time, and enable the master node to generate a CRC (Cyclic Redundancy Check) error after receiving the message.
Optionally, from the perspective of a slave node, fig. 5 shows another flow of the communication timing planning method provided in the embodiment of the present invention, and based on the method shown in fig. 5, the embodiment of the present invention may determine the slave node currently sending the non-handshake message, and as shown in fig. 5, the flow may include:
and step S30, acquiring bit information from the third position of the hyper-frame number.
Optionally, the bit information of the third position of the slave superframe number may be information of a higher bit position of the slave superframe number, and correspondingly, the third position of the slave superframe number may be higher than the first position and the second position of the slave superframe number; in one example, the third position from the superframe number may be bit information selected after removing the bit information of the second position from the superframe number; taking the second position of the slave hyper-frame number as the lower 6bit position of the slave hyper-frame number as an example, and the bit positions are sequentially reduced from the hyper-frame number according to the sequence from left to right, the embodiment of the invention can shift 6 bits from the slave hyper-frame number to the right, and then select information of a certain bit position (such as information of a first bit length) from the rest bit positions, thereby obtaining the bit information of the third position of the slave hyper-frame number, so that the bit information of the third position of the slave hyper-frame number is the information of the higher bit position of the slave hyper-frame number.
Step S31, comparing the bit information of the third position with first information, where the first information is used to indicate a node identifier of the slave node.
The embodiment of the invention can compare the bit information of the third position of the slave hyper-frame number with the first information indicating the node identification of the slave node, thereby determining whether the current slave node sends the message or not based on the comparison result. Optionally, the node identifier is, for example, a node number, and different slave nodes in the indoor distribution system may be distinguished by using different node identifiers.
After the slave node successfully handshakes with the master node, the slave node is assigned a valid node identifier, at which point the slave node may compare the bit information of the third position with the node identifier assigned to the slave node to implement step S31, and accordingly, in this case, the node identifier of the slave node may be regarded as an alternative form of the first information.
Step S32, if the comparison result is that the bit information of the third position is consistent with the first information, triggering to execute the step of sending a non-handshake message to the master node if the bit information of the second position of the slave hyper-frame number is a fourth value.
When the comparison result is that the bit information at the third position of the slave hyper-frame number is consistent with the first information, the embodiment of the invention can send the non-handshake message from the current slave node to the master node, so that the slave node can further send the non-handshake message to the master node when the bit information at the second position of the slave hyper-frame number is the fourth value. In an example, the first information indicating the node identifier of the slave node may be information of a first bit length (e.g., information of 6-bit length), and the embodiment of the present invention may determine the information of the first bit length at the high bit position in the slave superframe number (e.g., determine the information of 6-bit at the high bit position of the slave superframe number), obtain the bit information of the third position of the slave superframe number, thereby compare the bit information of the third position with the first information, and further when the comparison result is consistent, determine that the current slave node sends a non-handshake message, so that the slave node may send the non-handshake message to the master node when the bit information of the second position of the slave superframe number is a fourth value;
in the embodiment of the present invention, the bit information at the second position may be removed from the hyper-frame number, and the bit information (e.g., the information with the first bit length) may be selected from the bit information at the remaining positions to obtain the bit information at the third position.
In other optional implementations, the embodiment of the present invention may determine the slave node currently sending the slave handshake message, and the specific flow is as follows:
acquiring bit information from a fourth position of the hyper-frame number; comparing the bit information of the fourth position with second information, wherein the second information is random information; if the comparison result is that the bit information of the fourth position is consistent with the second information, triggering and executing the step of sending a slave handshake message for requesting to access the master node to the master node if the bit information of the second position of the slave hyper-frame number is a third value; wherein the fourth position of the slave superframe number is higher than the second position of the slave superframe number.
It should be noted that, when the slave node sends the slave handshake message, the slave node may not have the allocated node identifier, and at this time, the bit information of the fourth position of the high bit of the slave hyper-frame number may be compared with a random information (i.e., the second information), so as to determine the slave node currently sending the handshake message; if the bit information of the fourth position is consistent with the second information, the current slave node sends a handshake message, and the slave node can send a slave handshake message for requesting to access the master node to the master node when the bit information of the second position of the slave hyper-frame number is a third value;
in an example, the second information (random information) may be information of a second bit length (e.g., information of a length of 7bit or 8 bit), and in the embodiment of the present invention, the information of the second bit length at the high bit position (e.g., the information of a length of 7bit or 8bit at the high bit position of the super frame number) may be determined in the slave super frame number, so as to obtain the bit information of the fourth position of the slave super frame number, thereby comparing the bit information of the fourth position with the second information, and further when the comparison result is consistent, determining that the slave node sends the slave handshake message, so that the slave node may send the non-handshake message to the master node when the bit information of the second position of the slave super frame number is a fourth value;
in the embodiment of the present invention, the bit information at the second position may be removed from the hyper-frame number, and the bit information (for example, the information of the second bit length) may be selected from the bit information at the remaining positions, so as to obtain the bit information at the fourth position.
In a more specific optional implementation of the embodiment of the present invention, fig. 6 shows another signaling flow of the communication timing planning method provided in the embodiment of the present invention, and referring to fig. 6, the flow may include:
step S40, the master node obtains the master hyper frame number.
Step S41, if the bit information of the first position of the main hyper-frame number is the first value, the main node sends a main handshake message to the slave node, wherein the main handshake message at least carries the main hyper-frame number.
The master node may determine bit information of a first position of the master hyper-frame number, and if the bit information of the first position is a first value, the master node may send a master handshake message to the slave node.
And step S42, the slave node receives the master handshake message and synchronizes the slave hyper frame number according to the master hyper frame number.
And step S43, the slave node acquires the bit information of the fourth position of the slave hyper-frame number.
And step S44, if the bit information of the fourth position of the slave hyper-frame number is consistent with the random information and the bit information of the second position of the slave hyper-frame number is a third value, the slave node sends a slave handshake message to the master node.
The slave node may determine bit information of a fourth position of the slave superframe number, if the bit information of the fourth position of the slave superframe number is consistent with the random information, the slave node may further determine bit information of a second position of the slave superframe number, and if the bit information of the second position of the slave superframe number is further a third value, the slave node may transmit a slave handshake message to the master node.
And step S45, the master node allocates node identification for the slave node.
In an alternative implementation, after the master node receives a slave handshake message sent by the slave node to request access to the master node, a node identifier may be allocated to the slave node, and the node identifier allocated to the slave node may be a node identifier unoccupied by other nodes.
Step S46, if the bit information of the first position of the main hyper-frame number is a first value, the main node sends a main handshake confirmation message to the slave node, wherein the main handshake confirmation message at least carries the node identification allocated to the slave node.
And step S47, the slave node sets the node identification of the slave node according to the node identification carried by the master handshake confirmation message.
After the slave node receives the master handshake confirmation message, the node identifier can be set based on the node identifier carried in the master handshake confirmation message, so that different slave nodes in the indoor distribution system have different node identifiers.
Therefore, the slave node and the master node can realize successful handshake, the slave node is connected into the master node, and the subsequent slave node and the master node can carry out normal communication.
And step S48, if the bit information of the third position of the slave hyper-frame number is consistent with the node identification and the bit information of the second position of the slave hyper-frame number is a fourth value, sending a non-handshake message to the master node.
When the slave node and the master node carry out normal communication, the slave node and the master node can exchange non-handshake messages, the embodiment of the invention can determine that the current time is the opportunity for the slave node to send the non-handshake messages when the current time is determined to be the opportunity for the slave node to send the non-handshake messages based on the bit information of the third position of the slave super frame number and the bit information of the second position of the slave super frame number is the fourth value, so that the slave node can send the non-handshake messages to the master node.
In a more specific implementation example, the length of a cycle of one-time communication between the master node and the slave node may be defined as T1, and the unit is milliseconds; defining a communication period (T1), wherein the duration of the communication between the master node and the slave node is T2 in milliseconds, namely within T2 time, and the embodiment of the invention can send a message by the master node or send a message by the slave node based on the hyper frame number; further, in order to reduce the call complexity of the slave node, the embodiment of the present invention may employ a fixed communication timing, for example, a time range T0 with a length of N T1 cycles may be defined, and N communications may be performed within T0, for example, a specific communication interaction time example of the master node and the slave node may be referred to as shown in fig. 7; in the T0 time range, the number of communications of the master node sending messages and the slave node receiving messages is assumed to be X times, the number of communications of the slave node sending messages and the master node receiving messages is assumed to be Y times, wherein the number of communications is allocated to the handshake messages Y1 times, and the number of communications of the slave node receiving messages is allocated to the non-handshake messages Y2 times, then in a typical application scenario, a configuration example of specific data may be as follows: t1 ═ 160 msec, T2 ═ 3 msec, and N ═ 4, corresponding to T0 ═ 640 msec, X ═ 2, Y1 ═ 1, and Y2 ═ 1.
In the communication timing sequence planning method provided by the embodiment of the invention, the master node can determine the time for sending the message to the slave node based on the master hyper-frame number, and after the slave hyper-frame number of the slave node is synchronous with the master node, the slave node can determine the time for sending the message to the master node based on the slave hyper-frame number, so that the master node and the slave node can communicate with each other and the time for sending the message can be planned by the hyper-frame number, and the master node and the slave node in the indoor distribution system can better coordinate with each other; the communication time sequence planning scheme of the master node and the slave node provided by the embodiment of the invention is realized based on the hyper frame number, is very convenient and fast, and can reduce the complexity caused by planning the communication time sequence by the traditional central equipment.
