Fig. 1 is a flowchart illustrating a method for requesting uplink resources according to some embodiments of the present application, where the method for requesting uplink resources may be described as follows.
Step S101, the relay terminal broadcasts a discovery signal for establishing communication connection with the intelligent household equipment.
The smart home device (Remote UE) may be a Remote terminal, such as a dispenser, a doorbell, a refrigerator, a washing machine, a sound box, an air conditioner, a television, a disinfection cabinet, and other devices used in a home or office. A Relay terminal (Relay UE) uses a Relay technology to forward data between a base station and an intelligent home device, and one end of the Relay terminal is connected to the intelligent home device based on a wired interface or a wireless interface, for example, connected to the intelligent home device based on a pc5 interface, bluetooth or WIFI. The other end of the relay terminal is connected to a base station of the communication network based on a wireless interface (e.g., uu interface), and the relay terminal may be connected to an intelligent home device group, where the intelligent home device group may include one or more than two intelligent home devices.
The relay terminal may be a relay device that is set separately, or may also be a terminal device that is installed with a corresponding Application (APP), for example, a computer, a smartphone, a tablet computer, and the like.
In practical application, a user inputs a connection command for establishing connection with the smart home devices through a computer or a mobile phone terminal connected with the relay terminal or directly on the relay terminal, and the relay terminal broadcasts a discovery signal after receiving the connection command, so that the smart home devices receiving the discovery signal send a connection request to the relay terminal. Illustratively, the relay terminal may broadcast the discovery signal over the pc5 interface.
Step S102, the intelligent household equipment sends a connection request to the relay terminal after detecting the discovery signal.
For example, after the intelligent terminal device is powered on, whether a discovery signal broadcasted by the relay terminal exists at present is detected, and after the discovery signal broadcasted by the relay terminal is detected, a connection request is sent to the relay terminal so as to establish connection with the relay terminal. Illustratively, the smart home device may request to establish a connection with the relay terminal through a pc5 interface message.
And step S103, the relay terminal establishes communication connection with the intelligent household equipment according to the connection request.
For example, the relay terminal establishes connection with the smart home device according to the received connection request. Each relay terminal can establish communication connection with a group of intelligent household equipment, wherein the group of intelligent household equipment comprises one or more than two intelligent household equipment.
And step S104, the relay terminal receives uplink data sent by the intelligent household equipment through communication connection.
The upstream data may include any one of audio data, video data, image data, and text data. For example, when the smart home device is a doorbell, the uplink data received by the relay terminal may be image data; when the intelligent home equipment is an intelligent sound box, the uplink data received by the relay terminal can be audio data; when the intelligent household equipment is a television, the uplink data received by the relay terminal can be audio data, log text data and/or video data; when the intelligent home equipment is conference terminal equipment, the uplink data received by the relay terminal can be real-time interactive audio data and/or video data.
It should be noted that, in order to implement the data forwarding between the smart home devices and the base station by the relay terminal, the base station respectively establishes data channels between the relay terminal and the smart home devices and between the relay terminal and the base station, the data channels between the relay terminal and the smart home devices are collectively referred to as a first type of data channel, and the data channels between the relay terminal and the base station are collectively referred to as a second type of data channel, where the first type of data channel and the second type of data channel may both be used for transmitting uplink data and downlink data, and each data channel has a unique channel identifier. For example, a plurality of first-type data channels may be set between the relay terminal and each smart home device, and are respectively used for transmitting data of different Service types, and optionally, 2, 4, or 8 first-type data channels may be set between the relay terminal and each smart home device, where the Service types may be distinguished by Quality of Service (QoS) of the data, the data of different Service types correspond to different QoS, and the data of the same Service type corresponds to the same QoS. That is, in this embodiment, whether the service types are the same is determined according to whether the QoS of the service data is the same, if the QoS of the two service data is the same, the service types are determined to be the same, and if the QoS of the two service data is different, the service types are determined to be different.
For example, the traffic type/QoS classification of the uplink data may be as shown in table 1 below.
TABLE 1
Figure DEST_PATH_IMAGE002_15A
In table 1, CS and PS respectively indicate a Circuit Switched (CS) domain and a Packet Switched (PS) domain, and packets of all service types set QoS levels according to QoS attributes of services to which the packets belong. Because the signaling is special, its importance is greater than other data, and the data throughput of the signaling is low, the QoS level of the signaling data is set to be the highest in table 1, and other QoS types such as conversational, streaming, interactive, and background are also assigned different QoS levels according to their requirements for quality of service.
A plurality of second-class data channels may be set between the relay terminal and the base station, the number of the second-class data channels may be determined according to the number of the first-class data channels between the relay terminal and all the intelligent home devices connected thereto, so that each first-class data channel may correspond to one second-class data channel, optionally, the first-class data channels correspond to the second-class data channels one to one, for example, 256 second-class data channels are set between the relay terminal and the base station.
For example, the base station establishes different first-class data channels for data of different service types of different smart home devices, and the number of the first-class data channels between the base station and all the smart home devices is determined according to the number of the smart home devices and the number of the data of different service types. Corresponding to each first-class data channel, the base station establishes a corresponding second-class data channel between the relay terminal and the base station, namely, the first-class data channel and the second-class data channel are in one-to-one correspondence.
Since the communication links of the relay terminal and different smart home devices are different, the data channels of the relay terminal and different smart home devices are necessarily different. Moreover, for a data channel between the relay terminal and the same smart home device, since different service type data require different QoS, the data channels required to be established by the different service type data are also different, and therefore, even if the same smart home device is used, the data of different service types also need to be established by different data channels, for example, the base station respectively establishes different data channels for Circuit Switched (CS) domain data and Packet Switched (PS) domain data of the same smart home device.
Optionally, for multiple data with the same QoS of the same smart home device, the base station may establish a data channel, that is, for multiple data with the same QoS of the same smart home device, the base station establishes the same data channel for the multiple data with the same QoS between the relay terminal and the smart home device, and the multiple data with the same QoS may be transmitted through the data channel.
For example, as shown in fig. 2, a schematic diagram of data channel connection among a base station, a relay terminal, and smart home devices in some embodiments of the present application is shown, and a first smart home device 31A and a second smart home device 31B are taken as an example for description.
The first smart home device 31A needs to transmit first data and second data with different QoS, for example, the first data is CS domain data, the second data is PS domain data, the first data or the second data may be uplink data or downlink data, the base station 33 establishes a first data channel (whose channel identifier is: a first channel identifier a 11) and a second data channel (whose channel identifier is: a second channel identifier a 12) between the first smart home device 31A and the relay terminal 32 for the first data and the second data, where the first data channel is used for transmitting the first data, and the second data channel is used for transmitting the second data.
The second smart home device 31B needs to transmit third data and fourth data with different QoS, for example, the third data is CS domain data, the fourth data is PS domain data, the third data or the fourth data may be uplink data or downlink data, the base station 33 establishes a third data channel (whose channel identifier is a third channel identifier B11) and a fourth data channel (whose channel identifier is a fourth channel identifier B12) between the second smart home device 31B and the relay terminal 32 for the third data and the fourth data, the third data channel is used for transmitting the third data, and the fourth data channel is used for transmitting the fourth data. The first, second, third and fourth data channels are all first type data channels.
For transmitting the first, second, third and fourth data, the base station 33 establishes a fifth data channel (the channel identifier thereof is: fifth channel identifier a 21), a sixth data channel (the channel identifier thereof is: sixth channel identifier a 22), a seventh data channel (the channel identifier thereof is: seventh channel identifier B21) and an eighth data channel (the channel identifier thereof is: eighth channel identifier B22) between the base station 33 and the relay terminal 32, respectively, that is, the first data channel corresponds to the fifth data channel and is used for transmitting the first data; the second data channel corresponds to the sixth data channel and is used for transmitting second data; the third data channel corresponds to the seventh data channel and is used for transmitting third data; the fourth data channel corresponds to the eighth data channel and is used for transmitting fourth data. The fifth data channel, the sixth data channel, the seventh data channel and the eighth data channel are all second-class data channels.
When certain intelligent home equipment needs to send uplink data, the uplink data is sent to the relay terminal through the established data channel corresponding to the uplink data. The uplink data may be a plurality of data having the same QoS or a plurality of data having different QoS. When the uplink data is a plurality of data with the same QoS, the intelligent home equipment sends the plurality of data to the relay terminal through a data channel corresponding to the QoS. When the uplink data are a plurality of data with different QoS, the intelligent home equipment respectively sends the plurality of data to the relay terminal through the data channel corresponding to the QoS of each uplink data.
Step S105, the relay terminal determines whether the uplink data meets a preset condition that the uplink resource needs to be requested immediately, if so, step S106 is executed, otherwise, step S107 is executed.
The uplink resource is a resource required for the relay terminal to transmit uplink data to the base station, for example, for a 4G or 5G network, the uplink resource includes one of the following or any combination thereof: frequency point, frequency band, subcarrier spacing, power, format (modulation coding mode or code rate).
For example, the relay terminal may determine whether the uplink data meets a preset condition that the uplink resource needs to be requested immediately according to whether the transmission delay required by the uplink data is less than or equal to a preset transmission delay value. When the relay terminal determines that the transmission delay required by the uplink data is less than or equal to a preset transmission delay value, determining that the uplink data meets a preset condition that the uplink resource needs to be requested immediately, and when the transmission delay required by the uplink data is determined to be greater than the preset transmission delay value, determining that the uplink data does not meet the preset condition that the uplink resource needs to be requested immediately.
In another embodiment of the present application, the relay terminal may also determine whether a preset condition that requires immediate request of the uplink resource is satisfied according to whether the transmission priority of the uplink data is greater than or equal to the preset transmission priority, determine that the uplink data satisfies the preset condition that requires immediate request of the uplink resource when determining that the transmission priority of the uplink data is greater than or equal to the preset transmission priority, and determine that the uplink data does not satisfy the preset condition that requires immediate request of the uplink resource when determining that the transmission priority of the uplink data is less than the preset transmission priority.
In another embodiment of the present application, the relay terminal may also determine whether a preset condition that the uplink resource needs to be requested immediately is met according to whether the service type of the uplink data belongs to a service type that specifies that the uplink resource needs to be requested immediately.
For example, the base station sets a service type requiring immediate request of the uplink resource and sends the service type requiring immediate request of the uplink resource to the relay terminal, or sets a service type requiring immediate request of the uplink resource at the relay terminal through a terminal connected with the relay terminal, for example, sets a list of the service types requiring immediate request of the uplink resource, when the relay terminal determines that the service type of the uplink data belongs to the specified service type requiring immediate request of the uplink resource, it determines that the uplink data meets the preset condition requiring immediate request of the uplink resource, and when it determines that the service type of the uplink data does not belong to the specified service type requiring immediate request of the uplink resource, it determines that the uplink data does not meet the preset condition requiring immediate request of the uplink resource.
Step S106, the relay terminal immediately requests the base station for the uplink resource needed by the transmission of the uplink data.
When determining that the uplink data meets a preset condition that the uplink resource needs to be requested immediately, the relay terminal sends a request message for requesting to transmit the uplink resource of the uplink data to the base station, where the request message includes a channel identifier of the second type data channel and uplink resource information, and for example, the channel identifier and the uplink resource information of the second type data channel are carried by a packet header of the request message.
The channel identifier of the second type data channel is used for indicating a corresponding second type data channel, and the second type data channel is negotiated between the base station and the relay terminal and stored in the relay terminal, and the channel identifier of the second type data channel has a corresponding relation with the service type of the intelligent home equipment and the uplink data at the same time, namely the channel identifier of one second type data channel corresponds to the uplink data of one service type of the intelligent home equipment. In this embodiment, the channel identifier of the second type data channel carried in the request message corresponds to the uplink data requested to be transmitted.
And the uplink resource information is used for indicating the uplink resources required by the transmission of the uplink data.
Step S107, the relay terminal requests the uplink resource needed by the transmission of the uplink data based on other rules of requesting the uplink resource corresponding to the uplink data.
For example, the other rule for requesting uplink resources may be according to the time of receiving uplink data, the preset time for requesting uplink resources, or any other rule that does not require immediate request for uplink resources in an urgent manner.
And step S108, the base station allocates corresponding uplink resources and sends the uplink resources to the relay terminal.
For example, the base station negotiates with the relay terminal for resources corresponding to the uplink data, and sends the uplink resources to the relay terminal after receiving a request for requesting the uplink resources from the relay terminal.
For example, after receiving the request message, the base station allocates the uplink resource according to the channel identifier of the second type data channel and the uplink resource information included in the request message, and sends the uplink resource to the relay terminal, so that the relay terminal sends the uplink data through the uplink resource.
In summary, in the technical scheme of this embodiment, the relay terminal is connected to the multiple smart home devices, when a large number of smart home devices operate simultaneously, scheduling tasks of a data plane can be reduced, a load of a communication network is reduced, communication quality is improved, and whether uplink resources are immediately requested to be transmitted or not is determined for uplink data of different smart home devices, so that a specific service can be immediately transmitted, delay in transmission of the specific service is avoided, and unnecessary risks are avoided.
Fig. 3 is a flowchart illustrating another method for requesting uplink resources according to another embodiment of the present application, where the method for requesting uplink resources may be as follows.
Step S201, the relay terminal broadcasts a discovery signal for establishing communication connection with the intelligent household equipment.
Step S202, the intelligent household equipment sends a connection request to the relay terminal after detecting the discovery signal.
And step S203, the relay terminal establishes communication connection with the intelligent household equipment according to the connection request.
And step S204, the relay terminal receives uplink data sent by the intelligent household equipment through communication connection.
The specific implementation process of steps S201 to S204 in this embodiment is basically the same as steps S101 to S104 described in the above embodiment, and is not described herein again.
In step S205, the relay terminal determines whether the transmission delay of the uplink data is less than or equal to a preset transmission delay value, if the transmission delay of the uplink data is less than or equal to the preset transmission delay value, step S206 is executed, and if the transmission delay of the uplink data is greater than the preset transmission delay value, step S215 is executed.
The transmission delay required by the uplink data of different service types is different, for example, the transmission delay required by the conversational uplink data is smaller than the transmission delay required by the interactive uplink data, for example, the conversational uplink data is real-time service data of conversation voice, and the interactive uplink data is non-real-time data of an internet packet domain. In addition, even different uplink data of the same service type may require different transmission delays, for example, for conversational uplink data with the same QoS, the transmission delay required by the CS domain uplink data is smaller than the transmission delay required by the PS domain uplink data, for example, the transmission delay required by the PS domain voice uplink data is smaller than the transmission delay required by the PS domain real-time uplink data.
For example, the transmission delay setting of the uplink data may be as shown in table 2 below.
TABLE 2
Figure 646956DEST_PATH_IMAGE003
In table 2, CS and PS denote circuit switching and packet switching, respectively, and packets of all service types set a transmission delay according to QoS attributes (such as QoS type, domain, data type, transmission mode, etc.) of the service to which the packets belong. Since the signaling is special, its importance is greater than other data, and the data throughput of the signaling is low, the transmission delay of the signaling data is set to be minimum, i.e. the requirement is highest in table 2, and other QoS types such as conversational, streaming, interactive, and background also give different transmission delays according to their requirements on the quality of service. For data of the same QoS type, the Transparent Mode (TM) does not add any protocol overhead to an upper layer protocol, the anti-jamming capability is poor, so the transmission delay is small, the Unacknowledged Mode (UM) has no retransmission protocol, the transmission delay is small, and the Acknowledged Mode (AM) adopts automatic retransmission for error correction and has low requirement on the transmission delay, so the transmission delay is low. In short, according to specific service conditions, appropriate transmission delay values can be given to various types of data packets. After obtaining the table 2, when the relay terminal transmits a plurality of uplink data, the transmission priority may be determined according to the indicated transmission delay value.
The uplink data can carry transmission delay through the head of the uplink data, and the relay terminal can analyze the uplink data to obtain the transmission delay. In another embodiment of the present application, the base station may set transmission delays of different uplink data and send the transmission delays to the relay terminal, or the relay terminal device sets transmission delays of different uplink data, and when the relay terminal receives the uplink data, identifies a service type (e.g., QoS) or attribute information (e.g., a domain, a data type, a transmission mode, and the like) of the uplink data, and finds the set corresponding transmission delay.
In step S206, the relay terminal determines whether another uplink data is currently being transmitted, if the relay terminal determines that another uplink data is currently being transmitted, step S207 is performed, and if the relay terminal determines that another uplink data is not currently being transmitted, step S214 is performed.
The relay terminal respectively requests uplink resources for uplink data from different intelligent household devices or uplink data of different QoS of the same intelligent household device, so that the uplink resources can be staggered without conflict.
However, when the uplink data and the other uplink data have the same service type and are both sent by the same smart home device, because the same uplink resource and the same second type data channel are used, when the relay terminal receives the uplink data, another uplink data is being sent, and a collision exists. In order to save the request time and resources for requesting uplink resources and avoid collisions, the relay terminal needs to determine whether another uplink data is currently being transmitted.
For example, when the uplink data received by the relay terminal and sent by the smart home device is the first uplink data, another uplink data which is sending the smart home device is the second uplink data, where the service types of the first uplink data and the second uplink data are the same, that is, the QoS is the same, for example, the first uplink data is voice data of a session-based PS domain, and the second uplink data is real-time data of the session-based PS domain. For example, the first uplink data is voice alarm data of a session PS domain, and carries information of the voice alarm data, for example, the first uplink data is carried by a header, for example, when the temperature of some modules (e.g., chips or circuit boards) of the smart home device exceeds a predetermined value, the smart home device generates voice alarm data, and sets an emergency indication in the header of the voice alarm data, and the second uplink data is real-time data of the PS domain, for example, video data of a video conference call.
Step S207, the relay terminal determines whether the transmission delay required by the uplink data is less than the transmission delay required by another uplink data, if the transmission delay required by the uplink data is less than the transmission delay required by another uplink data, step S208 is executed, and if the transmission delay required by the uplink data is greater than or equal to the transmission delay required by another uplink data, step S212 is executed.
For example, the transmission delay required for the first uplink data: d is more than or equal to 200 milliseconds (ms) and less than or equal to 300 milliseconds (ms), and the transmission delay required by the second uplink data is as follows: d is more than or equal to 300 milliseconds (ms) and less than or equal to 400 milliseconds (ms), and D is transmission delay.
In steps S208-209, the relay terminal suspends transmitting another uplink data, transmits the uplink data using the uplink resource remaining after transmitting the another uplink data, and then performs step S210.
For example, since the first uplink data and the second uplink data have the same service type and may use the same uplink resource and the same second type of data channel, but the transmission delay required by the first uplink data is smaller than the transmission delay required by the second uplink data, the relay terminal suspends the transmission of the second uplink data in order to send the first uplink data as soon as possible, for example, to alarm as soon as possible, and sends the first uplink data by using the remaining uplink resource for sending the second uplink data.
Step S210, the relay terminal judges whether the uplink data is completely sent, if the uplink data is completely sent, the process is finished, and the uplink resource of the uplink data does not need to be requested to be transmitted; if the uplink data is not completely transmitted, the uplink data still has a part of data, and step S211 is executed.
For example, when the uplink resource remaining after the second uplink data is sent is greater than or equal to the uplink resource required for sending the first uplink data, the relay terminal may send all the first uplink data to the base station by using the uplink resource remaining after the second uplink data is sent, and when the uplink resource remaining after the second uplink data is sent is smaller than the uplink resource required for sending the first uplink data, the relay terminal sends part of the first uplink data to the base station by using the uplink resource remaining after the second uplink data is sent, and part of the first uplink data still remains.
In step S211, the relay terminal requests the base station for transmitting uplink resources required for the remaining untransmitted portion of the uplink data, and then performs step S220.
For example, the relay terminal sends a request message to the base station, where the request message is used to request the base station to transmit uplink resources required by the remaining unsent portion of the uplink data, the request message carries uplink resource information indicating the required uplink resources, and the request message may or may not carry a channel identifier of the second type data channel.
In step S212, the relay terminal continues to transmit another uplink data, and then performs step S213.
For example, when the transmission delay required by the first uplink data is greater than the transmission delay required by the second uplink data, the second uplink data needs to be sent as soon as possible, and the relay terminal continues to send the second uplink data; when the transmission delay required by the first uplink data is equal to the transmission delay required by the second uplink data, the transmission requirements of the first uplink data and the second uplink data are the same, but the relay terminal is already transmitting the second uplink data, so the relay terminal continues to transmit the second uplink data according to the received time sequence.
Step S213, when the relay terminal finishes transmitting another uplink data, it determines whether there is a surplus uplink resource, if there is a surplus uplink resource, step S209 is executed, and if the uplink resource is already used up, step S214 is executed.
For example, when the relay terminal finishes transmitting the second uplink data, it is determined whether uplink resources remain after the relay terminal finishes transmitting the second uplink data.
In step S214, the relay terminal immediately requests the base station for uplink resources required for transmitting uplink data, and then performs step S220.
For a specific implementation manner of this step, reference may be made to step S106 in the foregoing embodiment, which is not described herein again.
Step S215, the relay terminal requests uplink resources required for transmitting the uplink data based on other uplink resource requesting rules corresponding to the uplink data.
For a specific implementation manner of this step, reference may be made to step S107 in the foregoing embodiment, which is not described herein again.
Step S220, the base station allocates corresponding uplink resources and sends the uplink resources to the relay terminal.
For a specific implementation manner of this step, reference may be made to step S108 in the foregoing embodiment, which is not described herein again.
Fig. 4 is a flowchart illustrating another method for requesting uplink resources according to another embodiment of the present application, where the method for requesting uplink resources may be as follows.
Step S301, the relay terminal broadcasts a discovery signal for establishing communication connection with the intelligent household equipment.
Step S302, the intelligent household equipment sends a connection request to the relay terminal after detecting the discovery signal.
And step S303, the relay terminal establishes communication connection with the intelligent household equipment according to the connection request.
And step S304, the relay terminal receives uplink data sent by the intelligent household equipment through communication connection.
The specific implementation process of steps S301 to S304 in this embodiment is basically the same as steps S101 to S104 described in the above embodiment, and is not described herein again.
In step S305, the relay terminal determines whether the transmission priority of the uplink data is greater than or equal to the preset transmission priority, if the transmission priority of the uplink data is greater than or equal to the preset transmission priority, step S306 is performed, and if the transmission priority of the uplink data is less than the preset transmission priority, step S315 is performed.
The uplink data of different service types require different transmission priorities, for example, the transmission priority required by the conversational uplink data is greater than the transmission priority required by the interactive uplink data, for example, the conversational uplink data is real-time service data of conversation voice, and the interactive uplink data is non-real-time data of an internet packet domain. In addition, even different uplink data of the same service type may require different transmission priorities, for example, for conversational uplink data with the same QoS, the transmission priority required by CS domain uplink data is greater than that required by PS domain uplink data, for example, the transmission priority required by PS domain voice uplink data is greater than that required by PS domain real-time uplink data.
For example, the transmission priority setting of the uplink data may be as shown in table 3 below.

In table 3, CS and PS respectively represent circuit switching and packet switching, and packets of all service types are assigned with a priority value according to QoS attributes (such as QoS type, domain, data type, and transmission mode) of the service to which the packets belong. Since the signaling is special, its importance is greater than other data, and the data throughput of the signaling is low, the transmission priority of the signaling data is set to be the highest in table 3, and other QoS types such as conversational, streaming, interactive, and background are also given different transmission priorities according to their requirements on quality of service. For data of the same QoS type, the Transparent Mode (TM) does not add any protocol overhead to the upper layer protocol, and the interference rejection is poor, so the priority is higher, the Unacknowledged Mode (UM) has no retransmission protocol, and the priority is next higher, while the Acknowledged Mode (AM) adopts automatic retransmission for error correction and has low requirement on transmission delay, so the priority is lower. In short, according to specific service conditions, appropriate transmission priority values can be given to various types of data packets. After obtaining the table 3, when the relay terminal performs several uplink data transmissions, the transmission priority of the transmission may be determined according to the priority value.
The uplink data can carry the transmission priority through the head of the uplink data, and the relay terminal can analyze the uplink data to obtain the transmission priority. In another embodiment of the present application, the base station may set transmission priorities of different uplink data and send the transmission priorities to the relay terminal, or the relay terminal device sets transmission priorities of different uplink data, and when the relay terminal receives the uplink data, identifies the type (e.g., QoS) or attribute (e.g., emergency service indication) of the uplink data, and finds the set corresponding transmission priority.
Step S306, the relay terminal determines whether another uplink data is currently being transmitted, if the relay terminal determines that another uplink data is currently being transmitted, step S307 is executed, and if the relay terminal determines that another uplink data is not currently being transmitted, step S314 is executed.
The relay terminal respectively requests uplink resources for uplink data from different intelligent household devices or uplink data of different QoS of the same intelligent household device, so that the uplink resources can be staggered without conflict.
However, when the uplink data and the other uplink data have the same service type and are both sent by the same smart home device, because the same uplink resource and the same second type data channel are used, when the relay terminal receives the uplink data, another uplink data is being sent, and a collision exists. In order to save the request time and resources for requesting uplink resources and avoid collisions, the relay terminal needs to determine whether another uplink data is currently being transmitted.
For example, when the uplink data received by the relay terminal and sent by the smart home device is the first uplink data, another uplink data which is sending the smart home device is the second uplink data, where the service types of the first uplink data and the second uplink data are the same, that is, the QoS is the same, for example, the first uplink data is voice data of a session-based PS domain, and the second uplink data is real-time data of the session-based PS domain. For example, the first uplink data is voice alarm data of the conversational PS domain, which carries information that is alarm data, for example, the first uplink data is carried by a header, for example, when a temperature of some modules (e.g., chips or circuit boards) of the smart home device exceeds a predetermined value, the smart home device generates voice alarm data, and sets an emergency indication in the header of the voice alarm data, and the second uplink data is real-time data of the conversational PS domain, for example, video data of a video conference call.
Step S307, the relay terminal determines whether the transmission priority required by the uplink data is greater than the transmission priority required by another uplink data, if the transmission priority required by the uplink data is greater than the transmission priority required by another uplink data, step S308 is executed, and if the transmission priority required by the uplink data is less than or equal to the transmission priority required by another uplink data, step S312 is executed.
In steps S308 to 209, the relay terminal suspends transmitting another uplink data, transmits the uplink data using the remaining uplink resource for transmitting another uplink data, and then executes step S310.
For example, since the first uplink data and the second uplink data have the same traffic type, the same uplink resource and the same second type data channel may be used, but the transmission priority required by the first uplink data is higher than the transmission priority required by the second uplink data, so that the relay terminal suspends the transmission of the second uplink data as soon as possible, for example, an alarm is sent as soon as possible, and the relay terminal transmits the first uplink data by using the remaining uplink resource for transmitting the second uplink data.
Step S310, the relay terminal determines whether all the uplink data are sent, if all the uplink data are sent, the relay terminal ends the process without requesting uplink resources for transmitting the uplink data, and if all the uplink data are not sent, the relay terminal still has part of data left in the uplink data, and step S311 is executed.
For example, if the uplink resource remaining after the second uplink data is sent is greater than or equal to the uplink resource required for sending the first uplink data, the relay terminal may send all the first uplink data to the base station by using the uplink resource remaining after the second uplink data is sent, and if the uplink resource remaining after the second uplink data is sent is less than the uplink resource required for sending the first uplink data, the relay terminal sends part of the first uplink data to the base station by using the uplink resource remaining after the second uplink data is sent, and the first uplink data may still have part of the data.
In step S311, the relay terminal requests the base station for uplink resources required for transmitting the remaining untransmitted portion of the uplink data, and then performs step S320.
For example, the relay terminal sends a request message to the base station, where the request message is used to request the base station to transmit uplink resources required by the remaining unsent portion of the uplink data, the request message carries uplink resource information indicating the required uplink resources, and the request message may or may not carry a channel identifier of the second type data channel.
In step S312, the relay terminal continues to transmit another uplink data, and then performs step S313.
For example, when the transmission priority required by the first uplink data is lower than the transmission priority required by the second uplink data, the second uplink data needs to be sent as soon as possible, and the relay terminal continues to send the second uplink data; when the transmission priority required by the first uplink data is equal to the transmission priority required by the second uplink data, the transmission requirements of the first uplink data and the second uplink data are the same, but the relay terminal is already transmitting the second uplink data, so the relay terminal continues to transmit the second uplink data according to the received time sequence.
Step S313, when the relay terminal finishes sending another uplink data, it determines whether there is any uplink resource left, if so, step S309 is executed, and if not, step S314 is executed.
For example, when the relay terminal finishes transmitting the second uplink data, it is determined whether uplink resources remain after the second uplink data is transmitted.
In step S314, the relay terminal immediately requests the base station for uplink resources required for transmitting uplink data, and then performs step S320.
For a specific implementation manner of this step, reference may be made to step S106 in the foregoing embodiment, which is not described herein again.
Step S315, the relay terminal requests uplink resources required for transmitting the uplink data based on other uplink resource requesting rules corresponding to the uplink data.
For a specific implementation manner of this step, reference may be made to step S107 in the foregoing embodiment, which is not described herein again.
Step S320, the base station allocates corresponding uplink resources and sends the uplink resources to the relay terminal.
For a specific implementation manner of this step, reference may be made to step S108 in the foregoing embodiment, which is not described herein again.
In another embodiment of the present application, the relay terminal may also determine whether a preset condition that the uplink resource needs to be requested immediately is met according to whether the service type of the uplink data is determined to belong to a service type that specifies that the uplink resource needs to be requested immediately.
For example, the base station sets a service type requiring immediate request of the uplink resource and sends the service type requiring immediate request of the uplink resource to the relay terminal, or sets a service type requiring immediate request of the uplink resource at the relay terminal through a terminal connected with the relay terminal, for example, sets a list of the service types requiring immediate request of the uplink resource, when the relay terminal determines that the service type of the uplink data belongs to the specified service type requiring immediate request of the uplink resource, it determines that the uplink data meets the preset condition requiring immediate request of the uplink resource, and when it determines that the service type of the uplink data does not belong to the specified service type requiring immediate request of the uplink resource, it determines that the uplink data does not meet the preset condition requiring immediate request of the uplink resource.
Before requesting the uplink resource required by the uplink data to be transmitted from the base station, the relay terminal also determines whether another uplink data is currently transmitted, wherein the service types of the another uplink data and the uplink data are the same, belong to the specified service type which needs to request the uplink resource immediately, and are all transmitted by the intelligent home equipment.
And if the relay terminal is currently sending another uplink data, judging whether the transmission delay required by the uplink data is smaller than the transmission delay required by the other uplink data or judging whether the transmission priority of the uplink data is larger than the transmission priority of the other uplink data.
And if the transmission delay required by the uplink data is less than the transmission delay required by the other uplink data or the transmission priority of the uplink data is greater than the transmission priority of the other uplink data, the relay terminal suspends the transmission of the other uplink data, utilizes the remaining uplink resource for transmitting the other uplink data to transmit the uplink resource, and requests the base station for transmitting the remaining uplink resource required by the unsent part of the uplink data when the remaining uplink resource is not enough for transmitting all uplink data.
If the transmission delay required by the uplink data is greater than or equal to the transmission delay required by the other uplink data or the transmission priority of the uplink data is less than or equal to the transmission priority of the other uplink data, the relay terminal continues to send the other uplink data, and after the other uplink data is sent, whether the remaining uplink resources exist after the other uplink data is sent is determined. When the relay terminal determines that the residual uplink resources exist, the relay terminal transmits uplink data by using the residual uplink resources, and when the residual uplink resources are not enough to transmit all uplink data, the relay terminal requests the base station to transmit the uplink resources required by the residual unsent part of the uplink data; when the relay terminal determines that there is no remaining uplink resource, immediately performing a step of requesting the base station for uplink resources required for transmitting uplink data.
And if the relay terminal does not send another uplink data currently, immediately executing the step of requesting the base station for transmitting the uplink resource required by the uplink data.
For the relay terminal to transmit the uplink data and the other uplink data according to the transmission delay or the priority, reference may be specifically made to the description part of the embodiments corresponding to fig. 3 and fig. 4, and details are not described here again.
According to the technical scheme, the relay terminal is connected with the plurality of intelligent home devices, when a large number of intelligent home devices run simultaneously, scheduling tasks of a data plane can be reduced, the load of a communication network is reduced, the communication quality is improved, whether uplink resources are immediately requested to be sent or not is judged for uplink data of different intelligent home devices, a specific service can be sent immediately, delay of sending of the specific service is avoided, and unnecessary risks are avoided.
