A terminal that accepts a data forwarding service also allows simultaneous access to services of multiple access devices, which may include terminals operating as wireless stations, other access nodes (eg, macro station serving cells, or in addition to wireless small station UE nodes) Other types of small station nodes) can also remain connected to the macro base station at the same time.

A terminal having a wireless station working capability needs to be able to support a protocol stack related to mobile communication when operating as a wireless station.

The access node includes in the user plane protocol stack: a MAC entity and a PHY entity for terminals operating as wireless stations.

In the above description, the host access node refers to the collective name of the access node accessed by the terminal working as a wireless small station.

In the above control plane protocol stack architecture and user plane protocol stack architecture, protocol entities related to data security operations, such as PDCP entities, should be located in the control device, between the control device and the terminal receiving the data forwarding service. The cryptographic operation at the end can not parse the data of the terminal that accepts the data forwarding service for the host access node that passes through and the terminal that works as the wireless small station, especially the terminal that provides the data forwarding service, so that the non-operational use can be used. The merchant device protects the privacy of the terminal that accepts the data forwarding service while performing the data forwarding service.

Some protocol entities can be located elsewhere. For example, when the air interface link quality is relatively good, the RLC entity is placed on the user plane configuration of the terminal and the control device that accepts the data forwarding service, and the control plane configuration of the terminal and the control device that accepts the data forwarding service. In the case of poor air interface quality, in order to ensure high data transmission accuracy and interaction delay, the RLC entity can also be placed between the terminal working as a wireless station and the host access node. Face configuration. Specifically, as shown in FIG. 5, a schematic diagram of a second control plane protocol stack architecture is shown. After the terminal having the wireless station working capability in FIG. 5 performs the configuration of the wireless small station, the control plane protocol stack includes: a MAC entity, a PHY entity, and an RLC entity for the terminal that accepts the data forwarding service; and a host-oriented access node MAC entity, PHY entity, and RLC entity.

The terminal that accepts the data forwarding service includes: a MAC entity, a PHY entity, and an RLC entity for a terminal having wireless small station working capability; a PDCP entity and an IP entity facing the control device in the user plane protocol stack.

The access node includes in the user plane protocol stack: a MAC entity, a PHY entity, and an RLC entity for a terminal operating as a wireless station.

As can be seen from the above description, a terminal having a wireless station working capability can operate as a wireless station after performing the above protocol stack configuration and starting the wireless station working mode. A terminal with wireless station working ability enjoys the network service provided by the network operator when the wireless station working mode is not activated. Once the wireless station working mode is activated and the protocol stack configuration is completed, other terminals or access nodes can be carried. The data.

The premise that the terminal with wireless station working ability works as a wireless station needs to enter the wireless station working mode. There are two types of triggering modes for a terminal with wireless station working capability to enter the wireless station working mode:

Trigger mode 1: The control device triggers the terminal having the wireless station working capability to enter the wireless station working mode;

Trigger mode 2: The terminal with the wireless station working capability actively requests to enter the wireless station working mode by sending a request message.

Regardless of the trigger mode, the control device needs to send signaling to start the wireless station working mode and the wireless station configuration information to the terminal having the wireless station working capability, and the general procedure can be as shown in FIG. 7:

Step 701: The terminal having the wireless station working capability receives signaling for starting the working mode of the wireless station sent by the control device.

Step 702: The terminal having the wireless station working capability enters the wireless station working mode according to the signaling of starting the wireless station working mode.

The control device also sends wireless station configuration information to terminals with wireless station capability. The terminal having the wireless station working capability receives the wireless small station configuration information sent by the control device, and performs configuration of the wireless small station according to the wireless small station configuration information. The wireless station configuration information sent by the control device may include some or all of the following information: a Uu port working frequency point; a terminal having a wireless station working capability as a maximum transmitting power of the wireless station; and a time domain working pattern of the Uu port; ; Ux port time domain work pattern. Among them, the Uu port and the Ux port are defined as described above.

In step 702, the terminal having the wireless station working capability performs the configuration of the wireless station operation according to the wireless station configuration information sent by the control device, and after the configuration is completed, may further send the configuration signaling to the control device, and then A terminal having a wireless station working capability enters a station operating mode.

After the terminal having the wireless station working capability enters the small station working mode, it can work according to the manner specified by the access node in the prior art, for example, by sending public signaling such as a broadcast message, and receiving the terminal that needs the data forwarding service. After the response message, the terminal that accesses the data forwarding service is accessed. It is also possible to access the terminal that needs the data forwarding service instead of the normal access node, and access the terminal that needs the data forwarding service that is switched by the control device.

The triggering process of the above two trigger modes is described in detail below.

Trigger mode one

Before the control device triggers the terminal having the wireless station working capability to enter the wireless station working mode, for example, before step 701, the terminal having the wireless station working capability needs to report the information to the control device, and the reported information includes at least the control The device determines that the terminal has information on the ability of the wireless station to operate.

Preferably, the reported information further includes a measurement report, the measurement report including one or any combination of the following information: a backhaul link and transmission quality information of the terminal having the wireless station working capability; and a terminal having the wireless station working capability The link and transmission quality information of the surrounding terminal to the terminal having the wireless station working capability; the link and transmission quality information of the terminal itself around the terminal having the wireless small station working capability.

In step 701, the control device performs comprehensive processing and judgment on the information sent by the terminal having the wireless station working capability, and after determining that one of the terminals having the wireless station working capability is activated as the wireless station working mode, If the overall network efficiency can be improved, the signaling of the wireless small station working mode and the wireless small station configuration information are sent to the terminal having the wireless station working capability.

The processing of the remaining steps is the same as that shown in FIG. 7, and details are not described herein again.

Trigger mode two

In this trigger mode, before step 701, the terminal having the wireless station working capability determines whether to activate the wireless station working mode. If it is determined that the wireless station operating mode is activated, a request message to start the wireless station operating mode is sent to the control device. The control device determines to start the wireless small station working mode by starting the request message of the wireless small station working mode based on the request message for starting the wireless small station working mode sent by the terminal having the wireless station working capability.

In step 701, after receiving the request message, the control device performs comprehensive evaluation and judgment, determines that the condition for enabling the wireless station mode is met, and allows the terminal having the wireless station working capability to start the wireless station working mode, and then The terminal sends signaling to start the wireless station working mode and wireless station configuration information.

Preferably, the terminal having the wireless station working capability can also carry the service quality information that the terminal having the wireless station working capability can provide in the request message for directly transmitting the working mode of the wireless station to the control device, for example, the The frequency, bandwidth, processing speed, and storage capacity supported by the terminal having the wireless station working capability, so that the control device is more targeted to the wireless station configuration information sent by the terminal having the wireless station working capability, and can Overall network efficiency brings improvement. Preferably, the request message for starting the wireless station working mode further includes: a data transmission rate that the terminal having the wireless station working capability can provide.

In the following three cases, the terminal with the wireless station working ability can determine the working mode of the wireless station by itself:

Case 1: The terminal having the wireless station working capability sends a broadcast probe message, where the broadcast probe message is used to indicate that the terminal that sends the broadcast probe message has the wireless station working capability; the terminal with the wireless station working capability receives the need After receiving the response message returned by the broadcast probe message, the terminal of the data forwarding service sends a request message for starting the wireless station working mode to the control device. Preferably, the broadcast probe message includes a data transmission rate and quality of service information that the terminal having the wireless station working capability can provide.

Specifically, the broadcast probe message sent by the terminal having the wireless station working capability may be similar to the D2D broadcast signaling. The terminal that receives the broadcast probe message may determine that the terminal that sends the broadcast probe message has the wireless station working capability, and may also obtain the data transmission rate and the quality of service information that the terminal that sends the broadcast probe message can provide. After receiving the broadcast probe message, the neighboring terminal first determines the link quality of the terminal to the wireless small station working capability, and whether it needs the data forwarding service itself, and if it meets the requirements, the wireless terminal can The terminal of the small station working capability sends a response message to let the terminal having the wireless station working ability determine the terminal around which the data forwarding service is needed. After receiving the response message, the terminal having the wireless station working capability confirms that there is a terminal that needs the data forwarding service, and sends a request message for starting the wireless station working mode to the control device.

Case 2: A terminal with a wireless station working capability receives a broadcast probe sent by a terminal that needs a data forwarding service. a message, the broadcast probe message is used to detect a terminal having a wireless station working capability; and the terminal having the wireless station working capability confirms that the data forwarding service can be provided to the terminal that sends the broadcast probe message, and then sends the broadcast probe message The terminal sends a response message, and after receiving the acknowledgement message returned by the terminal that sends the broadcast probe message, according to the response message, sends a request message for starting the wireless station working mode to the control device.

Specifically, the terminal that needs the data forwarding service to send the broadcast probe message may be similar to the D2D (Device to Device) broadcast signaling, and detect whether there is a terminal with wireless small station working capability capable of providing the data forwarding service. After receiving the broadcast probe message, the terminal having the wireless station working capability determines whether it has the wireless station working capability, and determines whether the link quality between the terminals that need the data forwarding service meets the requirements, and meets the requirements. Thereafter, a response message is sent to the terminal that needs the data forwarding service. The terminal that needs the data forwarding service may receive a response message sent by more than one terminal having the working capability of the wireless small station, and at this time, according to the maximum data forwarding rate or link that each terminal having the working capability of the wireless small station can provide. Conditions such as quality, select one of the most suitable terminals with wireless station working ability, and send a confirmation message to the selected terminal with wireless station working ability. After receiving the acknowledgment message, the terminal having the wireless station working capability sends a request message for starting the wireless station working mode to the control device.

Case 3: The terminal having the wireless station working capability determines a request to start the wireless station working mode according to the change of the preset state, and sends a request message for starting the wireless station working mode to the control device.

For example, the wireless station operating mode preset by the terminal having the wireless station working capability is in the off state. When the user thinks that the preset state needs to be changed, it is determined that the request for starting the wireless station working mode needs to be started, and the user manually turns on the wireless station. The working mode switch, at this time, the terminal can directly send a request message for starting the wireless station working mode to the control device.

When the terminal having the wireless station working capability is configured according to the wireless small station configuration information sent by the control device, in addition to performing the protocol stack configuration as described above, the bearer mapping configuration is also performed, thereby performing data as a wireless small station. When forwarding services, it is possible to perform bearer management.

A terminal with a wireless station working capability and its host access node are required to perform bearer mapping configuration, and the process may include:

A host access node having a wireless station working capability and a terminal having a wireless station working capability, receiving a bearer mapping relationship sent by the control device, and performing uplink and/or downlink bearer mapping according to the bearer mapping relationship; In the mapping relationship, the bearer of the terminal that accepts the data forwarding service and the bearer that has the same or similar transmission attribute in the bearer of the terminal with the wireless station working capability are mapped to the same Ux port bearer, where the Ux port refers to the An interface between a terminal having a wireless station working capability and a host access node.

The bearer mapping relationship includes the bearer of the terminal that accepts the data forwarding service, the bearer of the terminal with the wireless station working capability, and the mapping relationship between the Ux port bearers. The terminal having the wireless station working capability can determine how to transmit the data in the bearer according to the bearer mapping relationship. The transmission attribute in each Ux port bearer is the same or similar. The quality of service (QoS) attributes are the same or similar. For example, the guaranteed bit rate (Guranteed Bit Rate, GBR)/non-GBR, the transmission error rate requirements are the same or similar, and the transmission delay requirement is required. Same or similar, the transmission priorities are the same or similar.

A terminal having a wireless station working capability establishes a dedicated tunnel for each bearer of the terminal that receives the data forwarding service when performing uplink transmission; and uses the corresponding dedicated tunnel to perform uplink data for the bearer of the terminal that currently transmits the uplink data. Package.

For example, as shown in FIG. 8, the bearer RB (English: Radio Bearer) 1 of UE1 and the bearer RB3 of UE2 have the same transmission attribute, are mapped to the bearer RB5 of the same Ux port for transmission, and have the capability of wireless station operation. The bearer RB4 of the terminal has the same transmission attribute as the bearer RB2 of the UE1, and is mapped to the bearer RB6 of the same Ux port for transmission.

When performing downlink transmission, the terminal having the wireless station working capability determines the target bearer of the corresponding target terminal according to the dedicated tunnel encapsulation header of the downlink data, and sends the downlink data to the target terminal. However, since the bearers of multiple different terminals are transmitted in the same Ux port bearer, the terminal having the wireless station working capability needs to distinguish the downlink data of different terminals after receiving the data transmitted in the Ux port bearer. In order to send downlink data to the correct target terminal.

The terminal having the wireless station working capability only transfers the data of the terminal receiving the data forwarding service according to the existing relay transmission mode, and the terminal having the wireless station working capability and the host access node will each be Each bearer of the terminal receiving the data forwarding service establishes a dedicated tunnel. There is a one-to-one correspondence between a dedicated tunnel established for each bearer and one bearer of each terminal that receives the data forwarding service, so each of the bearers on each bearer of the Ux port receives the data forwarding service. Data, each of which can identify which bearer of the terminal that receives the data forwarding service is identified by the identity of each bearer that establishes a dedicated tunnel. For example, a terminal with a wireless station working capability and a host access node establish a GPRS Tunnel Protocol User Plane (GTP-U) for each bearer of each terminal that receives the data forwarding service. The tunnel can identify which bearer of the terminal that receives the data forwarding service through the header of the GTP-U data.

The starting point or the end point of the data of the terminal having the wireless station working capability is itself, so that it is no longer necessary to establish a tunnel, and only the data encapsulated by the internal protocol, such as an RLC SDU (Service Data Unit). The data of the terminal having the wireless station working capability and the data of the terminal receiving the data forwarding service in the Ux port bearer can be parsed and distinguished in the following two ways.

One method is: the terminal having the working ability of the wireless station performs blind detection on the data received by the Ux port according to the dedicated tunnel unpacking mode and the protocol data packet unpacking mode, and the blind check succeeds according to the dedicated tunnel unpacking mode. And confirming that the target terminal of the data received by the Ux port is a terminal that accepts the data forwarding service, and if the blind detection succeeds according to the protocol packet unpacking mode, confirming that the target terminal of the data received by the Ux port is the A terminal with wireless station capability. For example, data in each bearer of a terminal having wireless station capability is encapsulated in a GTP-U. The data of the terminal with the capability of the wireless station is encapsulated by the RLC SDU. When the data is blindly detected, it is decoded according to the GTP-U data unpacking mode and the RLC SDU data unpacking method. In which way the decoding is successful, the encapsulation type of the data can be determined, and then the data is determined to have The data of the terminal of the wireless station working ability is still the data of the terminal having the wireless station working ability.

The other method is: the terminal having the wireless station working capability acquires the indication information carried in the data received by the Ux interface, where the indication information is used to indicate whether the target terminal is a terminal having the wireless station working capability or accepts data. Forwarding the terminal of the service, and determining a target terminal of the data received by the Ux port according to the indication information. For example, the indication information carried in the data is a specific field of the packet header, and the specific field has 2 bits, wherein the specific field is 00, the data is data of the terminal having the wireless station working capability; and 01 is representative The data is the data of the terminal that receives the data forwarding service first; the data representing 11 is the data of the terminal that receives the data forwarding service, and the like.

For example, the indication information carried in the data is a new specific field, and the newly added specific field and the data are re-encapsulated and located in the packet header of the re-encapsulated data, and the newly added specific field has 1 bit, wherein The newly added specific field is 0 to represent the data as data of the terminal having the wireless station working capability; and 1 to represent the data as the data of the terminal receiving the data forwarding service.

When a terminal having a wireless station working capability is serving a terminal that accepts a data forwarding service, it also needs to solve a problem that occurs when a terminal having a wireless station working capability moves.

There are two broad categories of mobility management involving terminals with wireless small station capabilities:

1. Mobility management of a terminal that accepts a data forwarding service under a terminal having a wireless station working capability;

Second, the mobility management of the terminal itself with wireless small station working ability.

The mobility management in different situations is separately described below.

For the mobility management of the terminal that accepts the data forwarding service under the terminal with wireless small station working capability, the terminal that accepts the data forwarding service regards the terminal that is serving the wireless station to be a normal connection. The ingress node, therefore, the mobility management of the terminal that accepts the data forwarding service is the same as the mobility management of the terminal under the access node in the prior art. Specifically, the reconfiguration process performed by the terminal that accepts the data forwarding service when it needs to replace the terminal with the wireless station working capability that is served by the terminal; the process of the terminal that accepts the data forwarding service switches to another terminal having the capability of working at the wireless station Wait. The technical means of specifically adopting the mobility management of the terminal receiving the data forwarding service under the terminal having the wireless station working capability will not be described herein.

For the mobility management of the terminal itself with wireless small station working ability, it can be divided into two situations. For the first case, the terminal having the wireless station working capability moves simultaneously with the terminal receiving the data forwarding service, but there is no relative movement between them. The most typical scenario in this case is that a terminal with wireless station capability is located in the same high-speed mobile vehicle as the terminal receiving the data forwarding service. At this time, when the terminal having the wireless station working capability moves only across the host access node, and the connection of the control device remains unchanged, the control device may need to The terminal with wireless small station working capability is reconfigured, and the corresponding protocol stack needs to be reset. For a terminal that is receiving a data forwarding service under a terminal having a wireless station working capability, in the case where it is not necessary to switch a terminal having a wireless station working capability, reconfiguration is not required, and a reset of the protocol stack is not required. When the terminal having the wireless station working capability moves outside the control area of the control device, the terminal having the wireless station working capability needs to perform the handover at this time, and the terminal that receives the data forwarding service under the service also needs to perform the handover. The switching process can be performed independently, or a certain binding can be performed to optimize the process.

For the second case, another terminal having the wireless station working capability moves, and the terminal having the wireless station working capability and the terminal serving the data forwarding service under it have relative movement. The most typical scenario in this case is that the terminal receiving the data forwarding service remains stationary, and the terminal having the wireless station working capability moves. At this time, the terminal having the working ability of the wireless small station needs to perform the reconfiguration or the handover process according to the situation. At this time, the terminal that receives the data forwarding service needs to find a new access node and perform a corresponding reconfiguration or handover process. The mobility process of the terminal having the wireless station working capability and the terminal receiving the data forwarding service shall be separately processed.

When performing mobility management, the terminal having the wireless station working capability receives the reconfiguration request message sent by the control device, and performs reconfiguration according to the reconfiguration request message; wherein the reconfiguration request message is the The control device transmits when it is determined that the terminal having the wireless station working capability moves between different access nodes connected to the control device; or

The terminal having the wireless station working capability receives the handover command sent by the core network to which the control device belongs, and switches to the target control device according to the handover command; wherein the handover command is that the core network determines that the core network The wireless station's working ability is transmitted when the terminal moves across the control plane anchor point.

When the following occurs, the wireless station working mode end process needs to be started: the terminal with the wireless station working ability needs to turn off the wireless station working mode for reasons such as power saving; the control device judges that it is no longer necessary to have the wireless station The working capability terminal starts the wireless station working mode; the service of the terminal receiving the data forwarding service under the terminal having the wireless station working capability has ended; for other reasons, the wireless station working mode needs to be turned off.

As shown in FIG. 9, a flowchart of a method for ending a wireless station working mode of a terminal having a wireless station working capability according to an embodiment of the present invention includes:

Step 901: The terminal having the working capability of the wireless small station receives the signaling of ending the working mode of the wireless small station sent by the control device.

Step 902: The terminal having the wireless station working capability cancels the wireless station configuration and exits the wireless station working mode according to the signaling of ending the wireless station working mode.

In step 901, when the control device ends the wireless station operating mode of the terminal having the wireless station working capability, it is first determined whether there is a terminal that is receiving the data forwarding service under the terminal having the wireless station working capability, and if so, The terminal that accepts the data forwarding service switches to another access node. At this time, the terminal having the wireless station working capability receives the signaling of ending the wireless station working mode sent by the control device.

In step 902, the terminal having the wireless station working capability cancels the wireless station configuration and exits the wireless station operating mode according to the signaling of ending the wireless station operating mode. The terminal with wireless station working ability will perform radio frequency adjustment, clear data buffer and clear wireless station configuration information, and then reply to the control device to complete the signaling of exiting the wireless station working mode, and transfer to the working mode of the ordinary terminal. .

Before step 901, if the terminal having the wireless station working capability needs to actively exit the wireless station working mode due to its own reasons, it is also required to send a request message for ending the wireless station working mode to the control device, and wait until receiving the control device sends the request message. After the signaling of the wireless station working mode is terminated, the wireless station working mode can be exited.

As shown in FIG. 10, a flowchart of a working method of a wireless terminal as another wireless terminal according to an embodiment of the present invention includes:

Step 1001: The control device sends, to the terminal having the working capability of the wireless small station, signaling for starting the working mode of the wireless small station, and is used to indicate that the terminal having the working capability of the wireless small station is configured according to the signaling mode for starting the working mode of the wireless small station.

The control device may also determine whether the terminal having the wireless station working capability is activated as the wireless station working mode by receiving the information sent by the terminal having the wireless station working capability indicating that it has the wireless station working capability.

After step 1001, the control device also sends a bearer mapping relationship to the terminal having the wireless station working capability and the host access node of the terminal having the wireless station working capability. In the bearer mapping relationship, the bearer of the terminal that accepts the data forwarding service and the bearer that has the same or similar transmission attribute in the bearer of the terminal with the wireless station working capability are mapped to the same Ux port bearer.

The control device forwards the received data of the service under the terminal having the wireless small station working capability after receiving the request for ending the wireless small station working mode sent by the terminal having the wireless small station working capability working in the wireless small station working mode. After the serving terminal switches to other access nodes, it transmits signaling to end the wireless station operating mode.

The control device can also actively send the signaling to end the working mode of the wireless small station according to the actual situation. For the specific implementation, reference may be made to the foregoing description, and details are not described herein again.
