Fig. 1 is a block diagram of a wireless access point AP10 according to an embodiment of the present invention. In the embodiment of the present invention, the AP10 is deployed in an operator network and is used for providing service services to a user terminal. The number of the APs 10 deployed in the operator network is multiple, and multiple APs 10 are communicatively connected to a wireless controller AC located outside the coverage area of the operator network, so as to perform terminal IP address centralized allocation for the user terminal within the coverage area of the operator network through the AC, so that the IP address of the user terminal when roaming among the multiple APs 10 within the coverage area of the operator network does not change. Meanwhile, a plurality of the APs 10 can provide local services for connected user terminals. In this embodiment, the AP10 includes a message processing apparatus 100, a memory 11, a processor 12, and a communication unit 13. The memory 11, the processor 12 and the communication unit 13 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines.

In this embodiment, the memory 11 may be configured to store an IP allocation flag, where the IP allocation flag is used to indicate a support status of the AP10 for centralized allocation of IP addresses of terminals. If the IP distribution flag is set, the AP10 currently supports the centralized distribution of the IP addresses of the terminals; if the IP assignment flag is not set, it indicates that the AP10 does not currently support terminal IP address centralized assignment. The value of the corresponding set of the IP allocation flag may be 1 or 0, and different configurations may be performed according to the specific situation.
The memory 11 is further configured to record a preset message Protocol used for indicating a terminal IP Address acquisition message, where the AP10 may determine, through the preset message Protocol, whether the acquired message is the terminal IP Address acquisition message corresponding to the preset message Protocol, where the terminal IP Address acquisition message is used to indicate that a user terminal sending the message needs to acquire an IP Address, and the preset message Protocol includes a DHCP (Dynamic Host Configuration Protocol) Protocol, an ARP (Address Resolution Protocol ), and the like.

In this embodiment, the processor 12 may be an integrated circuit chip having signal processing capabilities. The Processor 12 may be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like. The various methods, steps and logic blocks disclosed in the embodiments of the present invention may be implemented or performed.

In this embodiment, the communication unit 13 is configured to establish a communication connection between the AP10 and another external device through a network, and perform data transmission through the network. Wherein the other external devices include an AC and a user terminal.
In this embodiment, the AP10 ensures that the AP10 can allocate a fixed IP address to the user terminal by adopting a centralized IP address allocation method on the basis of providing a local service for local forwarding of a packet to the user terminal through the packet processing device 100 stored in the memory 11, so as to solve the problem of IP address change when the user terminal roams in an operator network, improve the packet processing performance of the overall packet processing flow, and reduce the packet processing delay of the packet processing flow.
It is understood that the configuration shown in fig. 1 is only a schematic configuration of the AP10, and the AP10 may include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
Fig. 2 is a schematic flow chart of a message processing method according to an embodiment of the present invention. In the embodiment of the present invention, the message processing method is applied to an AP10 shown in fig. 1 deployed in an operator network, where the AP10 is in communication connection with an AC and at least one user terminal, and the number of the APs 10 in the operator network is multiple. The following describes the specific flow and steps of the message processing method shown in fig. 2 in detail.
Step S210, receiving the message to be processed from the user terminal, and detecting whether the AP10 supports centralized allocation of the terminal IP address when the AP is in the local forwarding mode.
In this embodiment, the AP10 is deployed in an operator network and is in communication connection with at least one user terminal, and the user terminal obtains an IP address matched with the user terminal by sending a message to the AP10 or implements a local service. When receiving a message to be processed from a user terminal, the AP10 detects whether the AP is in a local forwarding mode or a centralized forwarding mode.
When the AP10 is in the centralized forwarding mode, the AP10 directly sends the to-be-processed packet to an AC communicatively connected to the AP10, and the AC processes the to-be-processed packet, that is, the AC performs centralized allocation on IP addresses of the user terminals, and performs centralized management and control on services of the user terminals.
When the AP10 is in a local forwarding mode, the AP10 detects whether it currently supports centralized allocation of IP addresses of terminals, wherein the AP10 stores therein an IP allocation flag indicating a support status of the AP10 for centralized allocation of IP addresses of terminals, and the step of detecting whether it currently supports centralized allocation of IP addresses of terminals includes:
detecting the setting condition of the IP distribution mark;
when the IP distribution flag is detected to be set, the AP10 is judged to support the centralized distribution of the IP addresses of the terminals currently, otherwise, the AP10 is judged not to support the centralized distribution of the IP addresses of the terminals currently.
Wherein, when the AP10 currently supports allocation in the terminal IP address set, the AP10 will correspondingly execute the step S220; when the AP10 does not currently support allocation in the terminal IP address set, the AP10 will correspondingly perform step S240.
Step S220, judging whether the message to be processed is a terminal IP address acquisition message.
In this embodiment, the terminal IP address acquisition message is used to acquire a corresponding matched IP address, and a preset message protocol used to represent the terminal IP address acquisition message is recorded in the AP10, where the preset message protocol includes a DHCP protocol and an ARP protocol. When the AP10 currently supports the distribution of the terminal IP address set, the AP10 may determine whether the message to be processed is a terminal IP address acquisition message by determining whether the message protocol corresponding to the message to be processed is the same as a preset message protocol.
Optionally, the step of determining whether the message to be processed is a terminal IP address acquisition message includes:
performing message protocol identification on the message to be processed to obtain a target message protocol corresponding to the message to be processed;
comparing the target message protocol with the preset message protocol;
and when the protocol identical to the target message protocol exists in the preset message protocol, judging that the message to be processed is a terminal IP address acquisition message, or judging that the message to be processed is not the terminal IP address acquisition message.
In this embodiment, when a target packet protocol corresponding to the packet to be processed is the same as any one protocol included in the preset packet protocol, it indicates that the packet to be processed is a terminal IP address acquisition packet, and a user terminal that sends the packet to be processed needs to acquire a matched IP address through the packet to be processed; when the target message protocol corresponding to the message to be processed does not exist in all protocols included in the preset message protocol, the preset message protocol indicates that the message to be processed is not a terminal IP address acquisition message but a service data message, and the user terminal sending the message to be processed needs to realize a service function of content matching through the message to be processed. When the AP10 determines that the message to be processed is a terminal IP address acquisition message, the AP10 will execute step S230; when the AP10 determines that the message to be processed is not a terminal IP address acquisition message, the AP10 will execute step S240.
Step S230, sending the to-be-processed packet to the AC, so that the AC or a server communicatively connected to the AC allocates an IP address to the user terminal corresponding to the to-be-processed packet.
In an implementation manner of this embodiment, when the AP10 is in a local forwarding mode and the AP10 determines that the to-be-processed packet is a terminal IP address acquisition packet, the AP10 sends the to-be-processed packet to the AC, so that the AC performs centralized IP address allocation for the ue sending the to-be-processed packet based on the to-be-processed packet, and sends an IP address feedback packet including an IP address matched with the ue to the AP10, so that the AP10 sends the IP address feedback packet to a corresponding ue, thereby implementing IP address allocation to the ue.
In another implementation manner of this embodiment, the AC is communicatively connected to a server for IP address allocation, when the AP10 is in a local forwarding mode and the AP10 determines that the to-be-processed packet is a terminal IP address acquisition packet, the AP10 sends the to-be-processed packet to the AC, and the AC sends the to-be-processed packet to the server, so that the server performs centralized IP address allocation for the user terminal that sends the to-be-processed packet based on the to-be-processed packet, and sends an IP address feedback packet including an IP address matching the user terminal to the AP10 via the AC, so that the AP10 sends the IP address feedback packet to the corresponding user terminal, thereby implementing IP address allocation for the user terminal.
In this embodiment, the step S230 may allocate a fixed IP address to the user terminal by adopting a centralized IP address allocation mode on the basis that the AP10 is in the local forwarding mode, so as to solve the problem of IP address change when the user terminal roams in the operator network.
Step S240, locally forwarding the to-be-processed packet based on the operator network, so as to implement a service corresponding to the to-be-processed packet.
In this embodiment, when the AP10 is in the local forwarding mode and the AP10 does not support centralized allocation of the terminal IP address currently, it indicates that the AP10 needs to forward the to-be-processed packet in a local forwarding manner to implement a local service corresponding to the to-be-processed packet, and at this time, the to-be-processed packet may be a terminal IP address acquisition packet or a service data packet.
When the AP10 is in a local forwarding mode, and the AP10 currently supports centralized allocation of a terminal IP address, but the to-be-processed packet is not a terminal IP address acquisition packet, it indicates that the to-be-processed packet is a service data packet, and the AP10 needs to provide a corresponding local service for the user terminal in a manner of locally forwarding the to-be-processed packet, thereby ensuring that the operator network can normally provide local services, improving the packet processing performance of the overall packet processing flow, and reducing the packet processing delay of the packet processing flow.
Fig. 3 is a second schematic flow chart of the message processing method according to the embodiment of the present invention. In this embodiment of the present invention, the message processing method may further include step S250 and step S260.
And step S250, receiving an IP address feedback message corresponding to the message to be processed from the AC.
In this embodiment, after the AP10 sends the to-be-processed packet determined as the terminal IP address acquisition packet to the AC, the AC or the server in communication with the AC generates a corresponding IP address feedback packet based on the to-be-processed packet, sends the IP address feedback packet to the AP10, and sends the IP address feedback packet to the corresponding matched user terminal through the AP 10. And the IP address feedback message comprises an IP address matched with the user terminal sending the message to be processed.
Step S260, sending the received IP address feedback packet to the corresponding user terminal, so as to complete IP address allocation to the user terminal.
In this embodiment, the IP address feedback packet records the MAC address of the user terminal, and the AP10 may send the IP address feedback packet to the corresponding user terminal according to the MAC address of the user terminal, and the user terminal analyzes the IP address feedback packet to obtain the allocated IP address corresponding to the user terminal.
Fig. 4 is a third schematic flow chart of the message processing method according to the embodiment of the present invention. In this embodiment of the present invention, the message processing method may further include step S209.
Step S209, configure a preset message protocol for indicating the terminal IP address acquisition message.
In this embodiment, the preset message protocol may be configured differently by the operation and maintenance personnel of the AP10 at the AP10 according to requirements, or configured differently by the operation and maintenance personnel of the operator network at the AC or the server communicatively connected to the AC according to requirements, and then the configured preset message protocol is sent to the AP10 for data configuration and work operation.

In the embodiment of the present invention, the message processing apparatus 100 is applied to the AP10 shown in fig. 1 deployed in an operator network, and the AP10 is communicatively connected to an AC and at least one user terminal, where the number of the APs 10 in the operator network is plural. In this embodiment, the message processing apparatus 100 includes an allocation detection module 110, a message determination module 120, and a message sending module 130.
The allocation detection module 110 is configured to receive a to-be-processed packet from the user terminal, and detect whether the AP10 supports centralized allocation of a terminal IP address when the AP is in a local forwarding mode.
In this embodiment, the AP10 stores an IP assignment flag indicating a support status of the AP10 for centralized assignment of terminal IP addresses, and the manner of the assignment detection module 110 detecting whether it supports centralized assignment of terminal IP addresses includes:
detecting the setting condition of the IP distribution mark;
when the IP distribution flag is detected to be set, the AP10 is judged to support the centralized distribution of the IP addresses of the terminals currently, otherwise, the AP10 is judged not to support the centralized distribution of the IP addresses of the terminals currently.
The allocation detecting module 110 may execute step S210 shown in fig. 2, and the specific execution process may refer to the above detailed description of step S210.
The message determining module 120 is configured to determine whether the to-be-processed message is a terminal IP address acquisition message when the AP10 currently supports distribution of a terminal IP address set.

In summary, in the message processing method and the message processing apparatus provided in the embodiments of the present invention, the message processing method can allocate a fixed IP address to the user terminal by adopting a centralized IP address allocation manner on the basis of providing a local service for local forwarding of a message to the user terminal, so as to solve the problem of IP address change when the user terminal roams in an operator network, improve the message processing performance of the overall message processing flow, and reduce the message processing delay of the message processing flow. The method is applied to an AP deployed in an operator network, the AP being in communication connection with an AC and at least one user terminal. Firstly, the method receives a message to be processed from the user terminal, and detects whether the AP supports centralized distribution of the IP address of the terminal when the AP is in a local forwarding mode. And then, when the AP currently supports the distribution of the terminal IP address set, the method judges whether the message to be processed is a terminal IP address acquisition message. Then, when the message to be processed is a terminal IP address acquisition message, the method sends the message to be processed to the AC so that the AC or a server in communication connection with the AC allocates an IP address to a user terminal corresponding to the message to be processed, thereby allocating a fixed IP address to the user terminal by adopting a centralized IP address allocation mode on the basis of local forwarding and solving the problem of IP address change when the user terminal roams in an operator network. Finally, when the message to be processed is not a terminal IP address acquisition message or the AP does not support terminal IP address centralized distribution, the method locally forwards the message to be processed based on the operator network to realize the service corresponding to the message to be processed, thereby ensuring that the operator network can normally provide local service, improving the message processing performance of the whole message processing flow and reducing the message processing delay of the message processing flow.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
