This application claims the priority of the Chinese patent application filed on July 18, 2017, the Chinese Patent Office, the application number is 201710586431.4, and the invention name is "the establishment method, device, computer storage medium and system of the communication route". The citations are incorporated herein by reference.

Technical field

The present application relates to communication technologies, and in particular, to a method, an apparatus, a computer storage medium, and a system for establishing a communication route.

Background technique

One of the development goals of mobile communication is to establish a wide-ranging interconnection network including various types of terminals, which is one of the starting points for the development of the Internet of Things within the framework of cellular communication. Among them, the Internet of Vehicles is an extension of the Internet of Things technology in the field of intelligent transportation systems. The Internet of Vehicles uses wireless communication, sensor detection and other technologies to collect information on vehicles, roads, and the environment, through vehicle-to-vehicle information interaction and sharing, and “vehicle-facilities”. Intelligent coordination and cooperation between the two, to achieve an integrated network of intelligent traffic management control, vehicle intelligent control and intelligent dynamic information services. At present, the car networking business mainly includes four major scenarios: platooning (fleet) business, remote driving business, sensor data sharing business scenario and automatic driving business scenario. In the fleet business scenario, a certain number of vehicles form a fleet of vehicles on the road, where the first vehicle (the first vehicle) is responsible for the management of the entire fleet, the distribution of driving information and the communication of the fleet with the outside world (such as an application server). In the process of high-speed driving, the distance between vehicles and vehicles can be as short as 1m. Therefore, a typical advantage of the team is that it can greatly improve road utilization and ease congestion. Since the distance between the two cars in the fleet is very low, the delay of the communication between the vehicles and the vehicles is required to be low enough. In the current agreement, the end-to-end delay of the vehicle communication within the fleet is within 10 ms.

It should be noted that the network architecture under the 4G shown in FIG. 3 is only an example, and does not limit the technical solution of the present application.

In the current fleet business scenario in the Internet of Vehicles, once the vehicle networking terminal accesses the mobile network, the mobile network establishes direct access information for these terminals. This situation ensures the delay requirement of the vehicle networking communication, but not every All car network terminals need to use low-latency services such as vehicle-to-vehicle communication. For example, some car-network terminals access the network only to listen to the broadcast, not to communicate with other car-network terminals. Therefore, in the prior art, the network element in the network needs to maintain more routing information, and the routing load of the network is heavy.

The fleet route is used to provide routing information for communication between fleet members for the second communication network element.

Specifically, when forming a fleet, the present application may be that the first vehicle (ie, the first team member in the fleet) interacts with other team members to form a fleet, or the first vehicle may send a fleet establishment request to the application server. When the application server authenticates the head car and allows the head car and other team members to form a fleet, the head car interacts with other team members to form the team. Based on this, the head vehicle can generate fleet information, which can include information for each team member in the fleet. Optionally, the fleet information can also include the team logo. The fleet information is used to trigger the first communication network element to establish a fleet route for the fleet, and send the fleet route to the second communication network element serving the team members, so as to provide the second communication network element with the route for communication between the fleet members in the fleet. information. Optionally, the route for communication between the members of the team may be a direct tunnel between the two second communication network elements, or may be another communication link between the two second communication network elements. The specific form of the route for communication is not limited as long as it can meet the delay requirement of the vehicle communication service.

The fleet information can contain information about the team members in the team that the first team member wants to form. The application server authenticates the members of the team to determine whether to allow the team members. Form a team. When the application server approves that the fleet can be established, optionally, the application server can assign the fleet's identity to the fleet, thereby transmitting fleet information including the fleet's identity to the vehicle network communication network element. Alternatively, the application server may not assign the team's logo to the fleet. It only determines whether the team members are allowed to form a fleet. When the application server approves that the fleet can be established, the application server will receive the first team member. The fleet information (in which only information about the team members is included in the fleet information) is forwarded to the vehicle network communication network element, and then the vehicle network communication network element assigns the team's identity to the fleet, thereby obtaining fleet information including the team's logo.

That is to say, the logo of the team can be assigned to the team after the formation of the team; it can also be assigned by the application server for the team, or after the car is sent to the car network communication network element, the car network The communication network element is allocated to the fleet, or it may be that the application server allows the establishment of the fleet, and the application server is allocated to the fleet.

FIG. 8 is a signaling flowchart of Embodiment 5 of a method for establishing a communication route according to an embodiment of the present disclosure. This embodiment relates to another implementation manner in which the first communication network element updates the fleet route. As shown in FIG. 8, based on the foregoing embodiment, the method may further include the following steps:

The first implementation manner: the first communication network element saves the previously received fleet information, so that after the first communication network element receives the updated fleet information, the first communication network element can update the updated fleet information and the location. The saved fleet information is compared to determine the type of fleet renewal and information on the updated fleet members in the fleet, ie to determine which fleet members have changed and what has changed. Thereafter, the first communication network element can store the updated fleet information, prepare for the next information comparison, and delete the previously saved fleet information.

The method for establishing a communication route provided by the present application, when the vehicle network communication network element detects a change in the fleet member in the fleet, sends updated fleet information to the first communication network element, so that the first communication network element is based on the updated The fleet information is determined as the address of the second communication network element served by the updated fleet member, and the fleet routing is updated in conjunction with the type of fleet update and the address of the second communication network element served for the updated fleet member, and the updated fleet route is routed The second communication network element serving the team members in the updated fleet is sent to implement the update process of the fleet route. In the method of the embodiment of the present application, the first communication network element updates the fleet route by updating on demand, thereby reducing the burden and workload of the network element maintenance route of the network.

The fourth embodiment and the fifth embodiment mainly describe the process of updating the fleet route on demand by the first communication network element. In the actual vehicle network communication, there is often a second member of the fleet that serves the team members due to movement in the network. In the case where the communication network element is switched, based on the situation, the first communication network element often needs to update the fleet route. The specific process of updating the fleet route based on the movement of the fleet members by the first communication network element is described below through two specific embodiments.

FIG. 9 is a schematic flowchart of Embodiment 6 of a method for establishing a communication route according to an embodiment of the present disclosure. The present embodiment relates to a specific process in which a first communication network element updates a fleet route based on the handover when the fleet member moves in the network, causing the second communication network element serving the fleet member to switch. In this embodiment, the first communication network element may be an SMF, an MME, or a PGW, and the second communication network element may be an UPF or an SGW. As shown in FIG. 9, the method includes the following steps:

S601: If the first communication network element receives the handover request sent by the target base station, the first communication network element learns, according to the handover request, that the serving base station of the first fleet member is handed over from the source base station to the target base station.

Specifically, when the first team member in the fleet has an air interface switch due to the movement, the serving base station of the first team member switches from the source base station to the target base station, and therefore, the destination base station sends a handover request to the first communication network element, A communication network element learns that the first fleet member in the fleet has switched from the serving base station to the destination base station based on the handover request.

S602: The first communication network element selects a target communication network element for the first team member according to the service range of the destination base station and the second communication network element.

When the first communication network element knows the location of the first team member (ie, the first team member is located under the coverage of the target base station, and the location of the first team member is actually the destination base station), the first communication network element is combined. Selecting, by the target base station and the service range of the second communication network element, a second communication network element from the plurality of second communication network elements as the target communication network element, where the target communication network element is the first communication network element as the first fleet A new communication network element selected by the member to serve the first fleet member.

S603: The first communication network element modifies an address of the second communication network element serving the first team member in the fleet route to an address of the target communication network element, and sends the updated fleet route to A second communication network element served by the team members of the fleet.

After the first communication network element obtains the updated fleet route, the updated fleet route is sent to the second communication network element serving the fleet members in the fleet, and the first communication network element can send the handover response message to the destination base station. The message may carry routing information of the target communication network element serving the first team member. It is assumed that the first member of the first team is UE2, the second communication network element originally serving UE2 is UPF2, and the second communication network element serving UE1 is UPF1. Due to the movement of the UE2, the first communication network element selects the UPF1 as the target communication network element serving the UE2, and then the first communication network element switches the address of the UPF2 originally served for the UE2 in the fleet route to the address of the UPF1. If the UE1 sends data to the UE2, the path of the data transmission may be UE1->UPF1->destination base station->UE2. It should be noted that the communication between UE1 and UPF1 also passes through a certain base station, but specifically Which base station is used in this application is not limited. If the UE2 needs to send data to the UE1 at this time, the data transmission path is UE2-> destination base station->UPF2->UPF1->UE1.
