Description
Technical Field
The embodiment of the invention relates to the technical field of wireless communication, in particular to a method, a system, a network and a terminal for transmitting data between the terminal and the network.
Background
A Temporary Block Flow (TBF) in a Radio communication technology is a communication transport Channel for supporting an uplink (Data Flow from a mobile Unit to a mobile communication system) and a downlink (Data Flow from the mobile communication system to the mobile Unit), and is a Physical connection used between two Radio Resource (RR, Radio Resource) entities to support unidirectional transmission of a Protocol Data Unit (PDU) on a Packet Data Physical Channel (PDPCH).
Please refer to fig. 1, which is a flowchart illustrating a method for uplink data transmission in the prior art. In the prior art, the process of sending uplink service data to a network by a terminal is generally as follows: the terminal sends request information for establishing one or more uplink TBFs to the network, wherein the request information comprises the uplink TBFs and Packet Flow Identifiers (PFIs) which the terminal wants to establish with the current cell. The PFI is used to mark radio resources related to Service data transmission, and a Quality of Service (QoS) parameter required for Service data transmission can be known according to the PFI.
After receiving the request information for establishing one or more uplink data transmission channels from the terminal in the uplink direction, the network knows the QoS required by the terminal for service data transmission according to the PFI in the request information. The network judges whether the current cell to be established by the terminal has enough resources to meet the requirement of the QoS parameter related to the terminal service. If yes, the network distributes the wireless resource aiming at the terminal service in the current cell and sends one or more TBF UPLINK ASSIGNMENT messages (PACKET UPLINK ASSIGNMENT/MULTIPLE TBF UPLINKASSIGNENT) to the terminal; otherwise, the network sends an access REJECT message (PACKET ACCESS REJECT) to the terminal.
Similarly, for the transmission of downlink data, after receiving the frame of establishing downlink service data, the network determines whether there are enough resources to satisfy the requirements of QoS parameters related to the terminal service in the current cell according to the PFI in the service data frame. If the current cell has not enough resources, the network sends access rejection information (PACKET access request) to the downlink data initiator, rejects the establishment, and discards the downlink data frame.
In the course of the invention, the inventor finds that at least the following problems exist in the prior art: in the prior art, when a data transmission channel is established, a terminal can only perform data transmission in a current cell, and if the current cell does not have enough resources to meet the data transmission requirement, a network can only cancel the transmission of the group of data. This affects the transmission of a large amount of service data, and thus cannot satisfy the service data transmission needs of users to the maximum, reducing the efficiency of data transmission in the network.

Detailed Description
One or more embodiments of the present invention provide a method for transmitting data between a terminal and a network, including:
when a data transmission channel is established, a network sends a switching command to a terminal, and the terminal transmits data by using the data transmission channel allocated to the specified target cell in the switching command.
When the switching command includes newly-created data transmission channel information that does not exist in the terminal, the terminal further includes, before transmitting data: and the terminal establishes a new data transmission channel corresponding to the target cell.
The data transmission channel is preferably a Temporary Block Flow (TBF) or a Radio Access Bearer (RAB) applied in a GPRS system.
The following detailed description of embodiments of the invention is provided in connection with the accompanying drawings.
Referring to fig. 2, it is a flowchart of an embodiment of a data transmission method according to the present invention, where the terminal is a sending end of uplink data transmission, the method specifically includes:
step 201: the terminal sends request information for establishing one or more uplink TBFs to a base station in the network, wherein the request information comprises PFI information corresponding to the uplink TBFs which are expected to be established in the current cell and the QoS required by the service data to be transmitted.
Step 202 to step 203: after receiving the request information for establishing the uplink TBF, the base station learns the QoS parameters required by the service data to be transmitted according to the PFI in the information, and judges whether the current cell of the terminal has enough resources to meet the QoS requirement of the service data transmission. If yes, the base station sends one or more uplink TBF assignment messages to the terminal, and the terminal establishes one or more corresponding uplink TBFs according to the assignment messages; if the current cell does not have sufficient resources, step 204 is performed.
Step 204: and sending a switching request to a core network, selecting a target cell and switching to the target cell. The base station performs corresponding processing according to the handover response 204a or 204b fed back from the core network, specifically: if the handover is successful, go to step 205 and step 206; otherwise, step 207 is performed.
Preferably, the target cell is specifically selected by the network, according to the strength of the neighbor cell signal periodically reported by the terminal, and the neighbor cell with a better signal is selected as the target cell.
The switching to the target cell may adopt different switching manners according to different network environments, for example, for packet switching in a 2G network, the switching of the base station to the target cell may specifically be: the base station sends a packet switching request message to a Serving GPRS Support Node (SGSN) of a network side to request to switch to the selected target cell. Wherein the packet handover request message includes a PFI corresponding to a QoS required for service data to be transmitted by the terminal. And after receiving the packet switching request message, the SGSN sends a packet switching request to a target wireless access system of the network. And the target wireless access system judges whether the target cell has enough resources to meet the QoS requirement or not according to the QoS parameter corresponding to the PFI. If so, allocating enough resources in the target cell to meet the QoS requirement required by the terminal for transmitting the service data, and sending a packet switching request response to the base station, wherein the packet switching request response message contains TBF allocated to the target cell and QoS information allocated to the TBF; otherwise, the switching is failed, and the SGSN sends a packet switching request response containing switching failure information to the base station. The base station performs the following step 204 or step 206 according to the packet handover request reply received from the SGSN.
It should be noted that: the specific implementation method for selecting and switching the target cell in the embodiment of the present invention is not limited to the above-described embodiment, and is within the scope of the present invention as long as the method meets the 3GPP (Third generation partnership Project) network specification.
Step 205: and the base station sends a grouping switching command to the terminal. Wherein, the packet switching command includes TBF allocated to the target cell and PFI corresponding to Qos information allocated to the target cell.
Step 206: and after the terminal receives the packet switching command from the base station, accessing the TBF distributed to the target cell according to the TBF contained in the switching command, and after the access is successful, transmitting the uplink data by using a data transmission channel distributed to the specified target cell in the switching command.
In addition, in the step 206, when there is a corresponding TBF that does not exist currently in the handover command, before the terminal accesses the target cell, it needs to establish a new uplink TBF corresponding to the target cell. And, the handover command may include a packet handover command or a Dual Transfer Mode (DTM) handover command according to different network environments.
In addition, in the above embodiment, if the selected target cell does not have enough resources to meet the data transmission requirement, the step of selecting the target cell and switching to the target cell in step 204 may be repeated until the target cell capable of meeting the service data transmission requirement is found, and then the steps 205 and 206 are executed. Or until a preset number of repetitions, if there is no suitable target cell, then step 207 is performed.
Step 207: and the base station sends an access rejection message to the terminal.
By the embodiment, when a data transmission channel is established and when the current cell has insufficient resources and cannot transmit data, the data transmission can be realized to the greatest extent by switching to other target cells; meanwhile, the embodiment may also transmit data by repeatedly selecting the target cell until a suitable cell is found when the selected target cell cannot transmit. Therefore, the success rate of data transmission can be further improved to the maximum extent, and the data transmission efficiency of the whole network is further improved.
Please refer to fig. 3, which is a flowchart illustrating an embodiment of a method for data transmission according to the present invention, the method includes:
step 301: and the network side sends downlink service data to the terminal through the base station, wherein the downlink service data comprises PFI information corresponding to the QoS required by the transmission of the downlink service data.
Step 302 to step 303: after receiving the downlink service data, the base station obtains the corresponding QoS parameter required for transmitting the data according to the PFI information in the service data. And the base station judges whether the current cell of the terminal has enough resources to meet the QoS requirement transmitted by the terminal according to the QoS parameter.
If the current cell meets the QoS requirement transmitted by the terminal, the base station sends one or more downlink TBF assignment information to the terminal, and the terminal establishes one or more corresponding downlink TBFs according to the assignment information; if the current cell does not have sufficient resources, step 304 is performed.
Step 304: and sending a switching request to a core network, selecting a target cell and switching to the target cell. The base station performs corresponding processing according to the handover response 204a or 204b fed back from the core network, specifically: if the switching is successful, executing step 305 to step 306; otherwise, go to step 307.
Preferably, the selecting the target cell specifically is that the network selects a neighboring cell with a better signal as the target cell according to the strength of the neighboring cell signal periodically reported by the terminal.
The switching to the target cell may adopt different switching manners according to different network environments, for example, packet switching in a 2G network, and the switching of the base station to the target cell may specifically be: and the base station sends a packet switching request message to the SGSN of the network side to request to switch to the selected target cell. Wherein the packet switching request command includes a PFI corresponding to a QoS required for service data to be transmitted by the terminal. And after receiving the packet switching request message, the SGSN sends a packet switching request to a target wireless access system. And the target wireless access system judges whether the target cell has enough resources to meet the QoS requirement or not according to the QoS parameter corresponding to the PFI. If so, allocating enough resources in the target cell to meet the requirement of QoS parameters required by the terminal for transmitting service data, and sending a packet switching request response to the base station, wherein the packet switching request response message contains TBF allocated to the target cell and QoS information allocated to the target cell; otherwise, the switching is failed, and the SGSN sends a packet switching request response containing switching failure information to the base station. The base station performs the following step 304 or step 306 according to the packet handover request reply received from the SGSN.
It should be noted that: the specific implementation method for selecting and switching the target cell in the embodiment of the present invention is not limited to the above-described embodiment, and is within the scope of the present invention as long as the method meets the 3GPP (Third generation partnership Project) network specification.
Step 305: and the base station sends a grouping switching command to the terminal. Wherein, the packet switching command includes TBF allocated to the target cell and PFI corresponding to Qos information allocated to the target cell.
Step 306: and after the terminal receives the packet switching command from the base station, accessing the TBF distributed to the target cell according to the TBF contained in the switching command, and after the access is successful, transmitting the uplink data by using a data transmission channel distributed to the specified target cell in the switching command.
In step 306, when there is a downlink TBF that does not exist currently in the handover command, before the terminal accesses the target cell, a new downlink TBF corresponding to the target cell needs to be established. And, the handover command may include a packet handover command or a Dual Transfer Mode (DTM) handover command according to different network environments.
In addition, in the above embodiment, if the selected target cell does not have enough resources to meet the data transmission requirement, the step of selecting the target cell and switching to the target cell in step 304 may be repeated until the target cell capable of meeting the service data transmission requirement is found, and then the steps 305 and 306 are executed. Or until a preset number of repetitions, if there is no suitable target cell, then the step 307 is performed.
Step 307: and the base station sends a switching cancellation message to a network side and discards the downlink service data.
By the embodiment, when data is transmitted and the current cell has insufficient resources and cannot transmit the data, the data can be transmitted as much as possible by switching to other target cells; meanwhile, the embodiment may also transmit data by repeatedly selecting the target cell until a suitable cell is found when the selected target cell cannot transmit. Therefore, the success rate of data transmission can be further improved to the maximum extent, and the data transmission efficiency of the whole network is further improved.
Based on the technical scheme, the embodiment of the invention also discloses a system for transmitting data between the terminal and the network, which comprises the terminal and the network; wherein,
the network is further used for sending a switching command to the terminal when a data transmission channel is established;
and the terminal is further used for transmitting data by using a data transmission channel allocated to the specified target cell in the switching command after receiving the switching command sent by the network.
