Detailed Description
In the solutions provided in the embodiments of the present application, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to better understand the technical solutions, the technical solutions of the present application are described in detail below with reference to the drawings and specific embodiments, and it should be understood that the specific features in the embodiments and examples of the present application are detailed descriptions of the technical solutions of the present application, and are not limitations of the technical solutions of the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.
A communication method provided by the embodiment of the present application is further described in detail below with reference to the drawings in the specification, and the method is applied to a RAN network, and a specific implementation manner of the method may include the following steps (a method flow is shown in fig. 2):
step 201, a base station establishes a mapping relationship between a first terminal and a second terminal according to identification information of an access terminal, wherein the first terminal is a terminal for sending data, the second terminal is a terminal for receiving data, and the identification information is used for representing information of a unique identification terminal.
Specifically, when the terminal accesses the RAN network, the terminal may report identification information thereof, for example, the identification information includes an International Mobile Equipment Identity (IMEI) of the terminal, an IP address of the terminal in the RAN network, or preset message identification information of a message sent by the terminal device. After the terminal reports the identification information, the base station acquires the identification information of the terminal accessed to the base station from the RAN network, and establishes a mapping relationship between a first terminal and a second terminal according to the identification information, wherein the first terminal is a terminal for sending data, and the second terminal is a terminal for receiving data. It should be understood that the first terminal and the second terminal provided in the embodiments of the present application are two different terminals connected to the same base station in the RAN network.
In the solution provided in the embodiment of the present application, because there are multiple types of the identification information, there are multiple types of mapping relationships established by the base station between the first terminal and the second terminal according to the identification information. The following description will take 3 preferable cases as an example.
Firstly, the identification information is an IMEI code, and the mapping relation is the mapping relation between the IMEI codes of the first terminal and the second terminal.
In order to facilitate understanding of the process of the base station establishing the mapping relationship between the IMEI codes of the first terminal and the second terminal according to the IMEI code, the establishment process thereof is briefly described below.
Specifically, in the solution provided in the embodiment of the present application, the IMEI code of the terminal is an international mobile equipment identification code, and is an electronic serial number composed of 15 digits, which corresponds to the meaning of each mobile terminal, and each mobile terminal is assigned with a global IMEI code after the assembly is completed. The first 6 digits in an electronic serial number composed of 15 digits of the IMEI Code represent a Type Allocation Code (TAC), and generally represent a terminal equipment model; the next 2 digits represent the Final Assembly Code (FAC), which generally represents the origin of the terminal equipment; next, 6 digits represent a Serial Number (SNR), which generally represents a terminal device production Serial Number; the last 1 digit represents a check Code (SP), usually "0", which is now on standby.
Further, an IMEI code list as a first terminal and an IMEI code list of a second terminal are pre-stored in a database of the base station, after the base station acquires the IMEI codes of the access terminals, the IMEI code of each access terminal is respectively compared with the IMEI code list of the first terminal and the IMEI code list of the second terminal to determine whether each access terminal is used as the first terminal or the second terminal, and then a mapping relation of the IMEI codes is established between the first terminal and the second terminal according to the type of each access terminal.
For example, the IMEI code of the first terminal is preset in the base station to 869898045001012, 869898046701012, 869898058201012, 869898046501012, 869898047601012; the IMEI code of the second terminal is 869898042201012, 869898053201012, 869898058701012, 869898045601012, 869898041001012. If there are 5 terminals accessing the base station, which are terminal 1, terminal 2, terminal 3, terminal 4 and terminal 5, respectively, wherein the IMEI code of terminal 1 is 869898045001012, the IMEI code of terminal 2 is 869898058201012, the IMEI code of terminal 3 is 869898042201012, the IMEI code of terminal 4 is 869898058701012, and the IMEI code of terminal 5 is 869898045601012; therefore, the terminals 1, 2 are first terminals, and the terminals 3, 4 and 5 are second terminals. See table 1 for the mapping relationship of IMEI codes between terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5 established by the base station.
TABLE 1
When the terminal 1 is a terminal for transmitting data, the base station may transmit data transmitted from the terminal 1 to the terminal 3 and/or the terminal 5, and when the terminal 2 is a terminal for transmitting data, the base station may transmit data transmitted from the terminal 1 to the terminal 4. In the solution provided in the embodiment of the present application, the mapping relationship of the IMEI code between the terminals is as follows: the terminal IMEI code 869898045001012 for sending data corresponds to the terminal IMEI code 869898042201012/869898045601012 for receiving data; the terminal IMEI code 869898058201012 from which data is transmitted corresponds to the terminal IMEI code 869898058701012 from which data is received.
And secondly, the identification information is an IP address, and the mapping relation is the mapping relation between the IP addresses of the first terminal and the second terminal.
In order to facilitate understanding of the process of the base station establishing the mapping relationship between the IMEI codes of the first terminal and the second terminal according to the IP address, the establishment process thereof is briefly described below.
Specifically, in the scheme provided in the embodiment of the present application, after the terminal accesses the RAN network, an IP address is allocated to each accessed terminal according to preset routing configuration information, and the IP addresses allocated to different accessed terminals are different.
The method comprises the steps that an IP address list serving as a first terminal and an IP address list of a second terminal are pre-stored in a database of a base station, after the base station acquires the IP address of an accessed terminal in a RAN network, the IP address of each access terminal is respectively compared with the IP address list of the first terminal and the IP address list of the second terminal, whether each access terminal serves as the first terminal or the second terminal is determined, and then the mapping relation of the IP addresses is established between the first terminal and the second terminal according to the type of each access terminal.
And thirdly, the identification information is preset message identification information, and the mapping relation is the mapping relation between the preset message identification information corresponding to the first terminal and the second terminal.
Specifically, in the scheme provided in the embodiment of the present application, the base station sets, in advance, the message identification information sent by each terminal, and the message identification information set by different terminals is different. The database of the base station is pre-stored as a message identification information list of the first terminal and a message identification information list of the second terminal.
After receiving uplink data sent by an accessed terminal, the uplink data carries message identification information, after acquiring the message identification information of the accessed terminal, the base station compares the message identification information of each accessed terminal with a message identification information list of a first terminal and a message identification information list of a second terminal respectively to determine whether each accessed terminal is used as the first terminal or the second terminal, and then establishes a mapping relation of the message identification information between the first terminal and the second terminal according to the type of each accessed terminal.
For example, three terminals accessing the same base station in the RAN network are UE1, UE2, and UE3, where the packet identification information set by the base station for UE1 is "ABCD", the packet identification information set by the base station for UE2 is "CDEF", the packet identification information set by the base station for UE3 is "BDGH", and according to a packet identification information list of a first terminal and a packet identification information list of a second terminal pre-stored in a database of the base station, UE1 carrying the packet identification information "ABCD" is determined as the first terminal, UE2 carrying the packet identification information "CDEF" and UE3 carrying the packet identification information "BDGH" are determined as the second terminal, so that the mapping relationship for establishing the packet identification information between the first terminal and the second terminal is: the UE1 carrying the packet identifier "ABCD" corresponds to the UE2 carrying the packet identifier "CDEF" and the UE3 carrying the packet identifier "BDGH".
Step 202, receiving the uplink data sent by the first terminal, determining the second terminal according to the uplink data and the mapping relationship, and sending the uplink data to the second terminal.
Specifically, in the solution provided in this embodiment, after the base station establishes the mapping relationship between the first terminal and the second terminal according to the identification information of the access terminal, since there are multiple mapping relationships between the first terminal and the second terminal, there are multiple ways for the base station to determine the second terminal according to the uplink data and the mapping relationship, and the following describes different mapping relationships respectively.
The method 1, if the mapping relationship is the mapping relationship between the IMEI code of the first terminal and the IMEI code of the second terminal, further includes, before receiving the uplink data sent by the first terminal: sending a request message to the access terminal, and receiving feedback information fed back by the access terminal according to the request message, wherein the feedback message carries an IMEI code of the access terminal; determining the first terminal and at least one third terminal according to the IMEI code of the access terminal and the mapping relation, wherein the third terminal is a terminal which corresponds to the first terminal and receives data;
determining the second terminal according to the uplink data and the mapping relationship, including: and determining the second terminal from the at least one third terminal according to the uplink data.
Specifically, refer to fig. 3 as a flowchart of data transmission provided in an embodiment of the present application. Before a first terminal sends uplink data, a base station sends a request message to a terminal accessed to the base station, wherein the request message is used for indicating the terminal to send an IMEI code of the terminal to the base station; after receiving the request message, the terminal generates a feedback message and sends the feedback message to the base station, wherein the feedback message carries the IMEI code of the terminal; and the base station determines the first terminal and at least one third terminal corresponding to the first terminal according to the IMEI code of the terminal carried by the feedback information and the mapping relation between the IMEI codes of the terminals established in the base station.
Further, the base station receives uplink data sent by the first terminal, and determines the second terminal from the at least one third terminal according to the uplink data sent by the first terminal.
Mode 2, if the mapping relationship includes a mapping relationship between the IP addresses or a mapping relationship between the message identification information, determining the second terminal according to the uplink data and the mapping relationship: determining the IP address of the first terminal or the message identification information of the first terminal carried in the uplink data; determining the at least one third terminal corresponding to the first terminal from the mapping relation according to the IP address of the first terminal or the message identification information of the first terminal; and determining the second terminal from the at least one third terminal according to the uplink data.
Specifically, referring to fig. 4, a flowchart of data transmission provided in the embodiment of the present application is shown. In fig. 4, a first terminal sends uplink data to a base station, where the uplink data carries an IP address of the first terminal or message identification information of the first terminal, and after receiving the uplink data of the first terminal, the base station determines at least one third terminal corresponding to the first terminal according to an established mapping relationship between the IP addresses or the message identification information, and then determines a second terminal from the at least one third terminal further according to the uplink data sent by the first terminal.
In the above mode 1 and mode 2, there are various modes in which the base station determines the second terminal from the at least one third terminal according to the uplink data sent by the first terminal, and specifically, in the solution provided in this embodiment of the present application, a preferred mode is taken as an example for description.
In a possible implementation manner, determining the second terminal from the at least one third terminal according to the uplink data includes: determining an IP address of each third terminal in the at least one third terminal, and determining an IP address of the second terminal carried in the uplink data; and determining the second terminal from the at least one third terminal according to the IP address of the second terminal.
In the solution provided in the embodiment of the present application, since the first terminal sends the uplink data to the base station through the RAN network, a data format of the uplink data is a radio frame format. Fig. 5 is a schematic diagram of a radio frame data structure provided in the embodiment of the present application. In fig. 5, the radio frame includes a frame header, a payload, and a frame trailer. The frame header includes a control field, a frame sequence number, and an address field, wherein the address field includes an IP address of a terminal that transmits wireless frame data, i.e., a source IP address, and an IP address of a terminal that receives the wireless frame data, i.e., a destination IP address. Therefore, the uplink data sent by the first terminal includes the IP address of the second terminal in addition to the IP address of the first terminal.
After determining at least one third terminal corresponding to the first terminal, the base station determines the IP address of each third terminal, determines the IP address of the second terminal carried in the uplink data, and then determines the second terminal from the at least one third terminal according to the IP address of the second terminal.
In the scheme provided by the embodiment of the application, the base station establishes a mapping relationship between the first terminal and the second terminal through the identification information of the access terminal, that is, a mapping relationship between the terminal sending data and the terminal receiving data, determines the second terminal corresponding to the first terminal according to the uplink data sent by the first terminal and the mapping relationship, and directly sends the uplink data from the first terminal to the second terminal through the RAN network, so that the uplink data is prevented from being transmitted to the second terminal through the transmission network and the core network, and the data transmission delay is reduced.
