Step 210, the first user equipment generates uplink information, where the uplink information includes the first information.

Step 220: The first user equipment sets indication information in the first information, where the indication information is used to indicate whether the first information is global information or local information.

Step 230, the base station receives the uplink information sent by the first user equipment.

Step 240, the base station determines whether the first information is global information or local information according to the indication information.

The embodiments of the present invention do not limit the manner in which the base station determines the global information and the local information. The base station may identify the global information and the local information in different ways, as long as the global information and the local information can be identified from the uplink information according to the indication information.

For example, the base station may also use multicast or The local information is sent to the target user equipment in unicast mode.

According to an embodiment of the present invention, the base station can identify global information and local information from the uplink information sent by the user equipment according to the indication information. If the indication information indicates that the uplink information contains the global information, the base station uploads the global information to the core network device. If the indication information indicates that the uplink information includes the global information If the information includes partial information, the partial information is directly delivered to other local user equipments. Since the local information does not need to be forwarded through the core network, the transmission delay of the local information is reduced, thereby reducing the delay of the communication system. In addition, the burden of the core network can be reduced when the local information is not processed by the core network.

It should be understood that the user equipment can report the global information and the local information at the same time, and can also report the global information and the local information separately. For example, in the process of accessing the network, the user equipment can In the process of and handover, the user equipment can report roaming and handover related information to the core network equipment through the base station, and after accessing the network, send position information and speed information to the base station, as well as the steering, braking and acceleration of the vehicle and other operation information.

Optionally, as another embodiment, if the base station determines that the first information is partial information, the method in FIG. 2 further includes: the base station sends the partial information to the core network device.

Specifically, the base station may not only directly deliver the local information to the local user equipment, but also upload the local information to the core network equipment at the same time.

The first partial information and the base station aggregate the partial information to obtain the second partial information using different aggregation methods.

Since the core network's requirements for the delay of the office information uploaded by the base station are different from the user equipment's requirements for the delay of the local information sent by the base station, for example, the user equipment requires a lower delay. When aggregating the local information sent by the same user equipment at different time points, the aggregation method can be used to improve the transmission efficiency, and when aggregating the local information sent to the user equipment, it can be considered to aggregate Local information sent at time points to reduce latency.

Through the aggregation of information, the load of information transmission can be reduced and the transmission efficiency can be improved.

According to the embodiment of the present invention, the aggregation manner of the local information aggregation by the base station may be that the base station aggregates local information contained in uplink information sent by the same user equipment in at least one first user equipment at different time points in the same time period.

For example, assuming that the speed of user equipment A at time T0 is 100km/h, and the speed of user equipment A at time T0+1, T0+2, T0+3, and T0+4 are all 100km/h, then user equipment A is at time period T0+1 After the information in ~T0+4 is aggregated, the local information can be set to "0" to indicate that the speed does not change between time T0+1 to T0+4 compared with time T0.

Alternatively, the aggregation manner for the base station to aggregate the local information may be that the base station aggregates the local information included in the uplink information at the same time point by different user equipments in the at least one first user equipment.

For example, the speed of user equipment A at time T0 is 100km/h, and the speed of user equipment B, C, D, and E at time T0 is also 100km/h, then the information of different devices at time T0 can be aggregated into 100km/h , that is, the speed of these users at time T0 is all 100 km/h.

Alternatively, the aggregation manner for the base station to aggregate the local information may be that the base station aggregates the local information included in the uplink information at different time points by different user equipments in the at least one first user equipment.

For example, the speed information of different user equipments A, B, C, D, and E respectively at times T0 to T0+4 may be aggregated into 100 km/h.

Since all the above-mentioned aggregation methods can remove redundant information in the local information and reduce the occupation of transmission resources, the transmission efficiency can be improved.

According to an embodiment of the present invention, the uplink information includes global information and local information sent by the same user equipment in the at least one first user equipment, or global information and local information sent respectively by different user equipments in the at least one user equipment.

Specifically, each user equipment can send at least one of local information and global information at the same time. For example, one user equipment can send global information and local information at the same time, or one user equipment can send global information, and another user equipment can send global information. Send local information.

According to an embodiment of the present invention, the indication information includes a newly added indication field in the first information, the indication field includes a first identification or a second identification, the first identification is used to indicate that the first information is global information, and the second identification is used to indicate The first information is local information; wherein, the first identification is different from the second identification.

Specifically, the above-mentioned indication information may be an indication field or indication field or indication bit in the sent data packet, which is used to indicate whether the information sent (or carried) in the data packet is global information or local information. Taking the indication field as an example, the embodiment of the present invention may set the indication field in the data packet of the uplink information. The indication field may be a newly added field in the data packet in the conventional frame format, or may be a reserved field in the data packet in the conventional frame format. For example, one bit (bit) is used to indicate local information or global information. For example, the first flag may be 0, which is used to indicate global information, and the second flag may be 1, which is used to indicate local information. According to the implementation of the present invention The example is not limited to this, and the first identifier and the second identifier may also be combinations of other numerical values and/or letters. In particular, when the indication field exists, it can also represent global information, and when the indication field does not exist, it can represent local information. In this case, the first identifier is the information filled in this field, and the second identifier is Null. .

Several ways of carrying the indication information are described in detail below. Various indication information in this embodiment of the present invention may be carried in the following manner.

1) The indication information may be borne (or carried) in a physical uplink control channel (Physical Uplink Control Channel, PUCCH). For example, the uplink information may be composed of control information and data information, wherein the control information is sent on the PUCCH, and the data information is sent on the Physical Uplink Shared Channel (PUSCH), and the embodiment of the present invention may be carried on the PUCCH ( or carry) indication information, and the global information or local information is carried on the PUSCH.

2) The indication information may be indicated by reference signals, that is, global information and local information may be indicated by different reference signals. For example, it is indicated in a Reference Signal (RS) in each resource block (Resource Block, RB). The indication information can be improved by improving an existing reference signal, or a new reference signal can be designed.

3) The indication information can be indicated by a preamble, that is, different preambles can be used for the global information and the local information.

Since the user equipment clearly identifies the global information and the local information in the uplink information, the base station can classify the uplink information by simply reading the indication information, so that the base station can quickly distinguish the local information and the global information, and can quickly deliver the local information information, thereby minimizing the delay of information transmission.

As an alternative to including an indication field in the uplink information, in 220, the base station may determine the global information and the local information from the uplink information according to the content and/or attribute characteristics of the global information and the local information.

For example, the global information that needs to be processed by the core network may be security and authentication information such as user IDs and passwords, while the local user equipment needs to process location information such as longitude and latitude. The base station can analyze the difference in content between the two kinds of information. to identify these two types of information. Alternatively, the base station may identify the two types of information according to the characteristics of the two types of information (eg, the length of the data packet). This solution can be realized without modifying the user equipment, which simplifies the design of the system.

According to an embodiment of the present invention, the indication information includes target address information; if the target address information indicates that the sending target of the first information is a core network device, the first information is global information; if the target address information indicates that the sending target of the first information is When there is at least one second user equipment, the first information is local information.

Specifically, the global information and the office information can be determined according to whether the uplink information is set with a target terminal address and a specific value. For example, the user equipment may set the target address in the uplink information when sending the global information, but may not set the target address in the uplink information when sending the local information. In this way, if the base station determines that there is no target address in the uplink information, it can be considered that The uplink information is local information, and if it is determined that there is a target address in the uplink information, it is considered that the uplink information is global information. For another example, the user equipment can set the target address to a specific value when sending uplink information. For example, when it is set to 1, it means that the uplink information is local information, and when it is set to a value of 2, it means that the uplink information is global. information.

According to an embodiment of the present invention, the indication information includes frame format information, the frame format information of the global information is different from the frame format information of the local information, and the frame format information includes one of the following information: a modulation mode of the first information, a frame of the first information The length and number of fields of the first information frame.

Specifically, the user equipment can use different modulation methods at a specific location to modulate the global information and the local information, and the base station distinguishes the global information and the local information by judging the modulation method of the uplink information. For example, the global information uses ordinary bi-phase information. Shift keying (Binary Phase Shift Keying, BPSK) modulation, and local information using 90 degrees (or 45 degrees) rotated BPSK modulation. The user equipment can also set different frame lengths for the uplink information, and the base station distinguishes the global information and the local information by judging the frame length of the uplink information. The user equipment can also set the number of different fields for the uplink information. The base station distinguishes the global information and the local information by judging the number of fields of the uplink information. For example, the global information contains M fields, the local information contains N fields, and M is not equal to N, M and N are integers.

According to an embodiment of the present invention, the first user equipment and the second user equipment include an on-board unit attached to a vehicle in an intelligent transportation system, wherein the global information includes information for the intelligent transportation system to perform traffic control, and the local information includes information for at least A second user equipment performs driving control information.

Embodiments of the present invention may be applied to intelligent transportation systems. For example, in an intelligent transportation system, the above-mentioned global information may be information used by core network equipment to implement security authentication of user equipment or to implement roaming and handover during high-speed travel. For example, information related to security authentication may include user IDs and passwords, etc. Information, information about roaming and handover can include measurement results and other information. For example, the local information may be the movement information of the user equipment, such as position information and speed information. In the intelligent transportation system, in order to plan the route, the base station sends information about road congestion to all user equipments under its coverage. In this case, broadcasting can be adopted. In order to prevent the specific location information of the vehicle from the rear-end collision of the fire truck, the base station only needs to notify the nearby user equipment. In this case, the multicast method can be used. Each vehicle can first send the above information to the base station. The base station analyzes the above information, identifies the information that needs to be processed by the core network equipment (that is, global information) and the information that needs to be processed by other local vehicles (that is, local information), reports the global information to the core network equipment, and sends local to other local vehicles. information. The method for identifying the above-mentioned global information and local information by the base station is as described in the above-mentioned embodiment, and details are not described herein again.
