BACKGROUND With the popularity of the mobile Internet and smart phones, the demand for mobile data traffic is rapidly increasing. In order to increase capacity, there are currently two main solutions.

One solution is to use a wireless local area network (WLAN) system. The WiFi system is loosely coupled to the 3G system, and is authenticated and billed in the core network of the 3G system. WiFi Use WiFi for hotspot coverage, which can play a better role in data traffic distribution. However, since the WiFi system and the 3G system are two different standard systems, it is usually required that the user manually select the network to be accessed, and it is difficult to implement smooth switching between the two access networks. Moreover, the amount of link shield cannot be guaranteed. The WiFi uses the unlicensed ISM (Industrial, Scientific, Medical, Industrial, Scientific, and Medical) bands, and there is interference with various devices such as WiFi and microwave ovens. It is difficult to set up a network at the same time. Because its working frequency band is an unlicensed frequency band, if multiple operators are networking in the same area, if there is no good coordination and unified planning, it will cause mutual interference.

Another solution is to use a home base station (Femto, HNB or He B). The home base station can be connected to the core network of the 3G system through a device such as a macro base station. The cost of the home base station is lower, the deployment is more flexible, and it plays a certain role in indoor data distribution, and can also support carrier-class services. However, the home base station does not further optimize and optimize the indoor service characteristics. Taking LTE (Long Term Evolution) as an example, the LTE complete protocol architecture and interface are basically adopted, and the same physical layer design and the same RF requirements, so the implementation complexity is not greatly reduced.

Delivery of signaling packets between the UE and the application server;

The transmission of signaling information between the AP and the application server;

Interaction of authentication information between the gateway and the AP;

The management information is exchanged between the gateway and the AP.

The following describes the functions of each module through several typical application scenarios.

During the AP attachment process, the local authentication unit learns that the Ia-g interface module 204 is connected to the AP and then authenticates the AP.

The Ia-g interface module 204 establishes an interface with the AP after the authentication is passed. After the interface is established, the device management unit performs synchronization operations and parameter configuration on the AP.

In the UE attach procedure, after the control and management mode 202 block obtains the service connection request sent by the UE, the QoS class is selected for the UE. The IP module 203 encapsulates the data from the UE into IP data packets for addressing, routing, and QoS control to transmit IP data packets to the Internet while controlling and counting the data traffic of the IP data packets.

The above is an introduction to the gateway. In this embodiment, the internal structure and function of the AP are also improved in order to reduce the complexity of the system. See the following embodiments.

Referring to FIG. 3, the AP in this embodiment includes: a radio frequency module 301, a physical layer processing module 302, a layer 2 module 303, and an Ia-g interface module 304. The AP may be specifically an access device such as a base station (e.g., an evolved base station (e B )).

A radio frequency (RF) module 301 is configured to perform transmission of a downlink data signal and reception of an uplink data signal. The relevant design and parameters of the RF module can refer to the 3GPP related protocols for TD-LTE. In design, according to different scenarios and application requirements, the requirements of RF parameter indicators can be appropriately relaxed to reduce equipment costs.

a physical layer (PHY) processing module 302 for encoding or decoding data signals into frames, and for modulating Or demodulation, where the data signal includes an uplink data signal and a downlink data signal. The physical layer processing module 302 is also used for physical layer operations such as ΜΙΜΟ (multiple input multiple output) multi-antenna transmission, multi-carrier aggregation, link adaptation, control channel configuration, primary and secondary synchronization signals, reference symbol configuration, and the like. The downlink layer encodes the MAC layer data packet into a frame modulation and transmits it to the radio frequency module, and the uplink radio frequency signal is processed and processed to form a MAC layer data packet. The detailed design of the physical layer refers to the relevant protocol of 3GPP regarding TD-LTE. In design, in order to reduce cost and improve transmission efficiency, physical layer transmission mode can be reduced, larger period measurement and feedback can be configured, and fewer control channels and reference symbols can be configured.

Layer 2 module 303 is used for wireless link control and media access control of data, and for wireless resource control of connection management. The layer 2 module 303 mainly includes a MAC part, an RLC (Radio Link Control) part, and an RRC (Radio Resource Control) part.

The MAC part is mainly used for packet scheduling, channel mapping and multiplexing, transmission format selection, and HARQ (Hybrid).

Automatic Repeat Request, hybrid automatic repeat request) function. The scheduling part retains the QoS level and required interfaces, and can implement QoS guarantee for high-level data packet transmission. The function of channel mapping and multiplexing is to map the final various MAC packet multiplexes onto the physical channel for transmission. The transport format is chosen to be the embodiment of the link adaptation function at the MAC layer, and the block size of the packet transmission can be selected. The HARQ function implements fast error retransmission based on the feedback of the physical channel to ensure the link shield.

The RLC part is mainly used to convert IP packets into MAC packets suitable for MAC layer transmission, and to reassemble and upload MAC packets to the IP layer. The header compression function compresses IP packets of the same IP address to improve the efficiency of small data transmission and improve the efficiency of small data transmission. The segmentation cascade segments IP packets into MAC packets suitable for MAC transmission, or cascades MAC packets into IP packets. The reordering implements sorting packets that are due to incorrect retransmissions rather than sequential arrivals. The data encryption function completes the encryption of the data packets in the air interface according to the requirements of the system configuration, and improves the security. This function can implement different encryption methods according to the security level configured by the upper layer.

The RRC part implements system information broadcasting, AP and user access authentication and security management, authentication between APs and gateways, and wireless link management functions. At the same time, the RRC part is also responsible for receiving management configuration information from the gateway, and implementing parameter configuration and synchronization functions of each layer. In order to further improve the terminal power saving, the RRC part also includes a DRX (Discontinuous Receiption) technology, which supports the terminal to wake up for a long period of time for non-continuous data reception and monitoring. For example, the maximum DRX period in 3GPP is 2560ms. In this embodiment, it can be further supported to 25600ms in order to meet the needs of indoor low-speed mobile and high-speed data transmission.

The Ia-g interface module 304 is configured to transmit data packets, signaling packets, and various information to an IP module in the gateway or the AP. The Ia-g interface module 304 performs at least one of the following operations:

The transfer of data packets between the layer 2 module and the IP module;

Delivery of signaling packets between the UE and the gateway;

Delivery of signaling packets between the UE and the application server;

The transmission of signaling information between the AP and the application server; Interaction of authentication information between the gateway and the AP;

The management information is exchanged between the gateway and the AP.

The AP may also include an IP module 305, as shown in FIG. The IP module 305 is configured to perform at least one of the following operations: IP packet encapsulation, IP data unpacking, IP address allocation, addressing and routing, QoS differentiated services, flow control, and statistics.

Specifically, the IP module includes:

The data encapsulating unit is configured to encapsulate the data packet uploaded by the AP layer 2 module into an IP data packet in the uplink, and then decapsulate the IP data packet to the layer 2 module after being downlinked.

An addressing and routing unit for addressing and routing IP packets.

In order to reduce the complexity of the system, the preferred solution is: The layer 2 module 303 is connected to the gateway or the IP module 305 in the AP through the Ia-g interface module 304. That is to say, the AP does not include a PDCP (Packet Data Convergence Protocal) module and a NAS (Non-Access Stratum) layer module. The Ia-g interface module 304 directly transmits the data, signaling, information, and the like obtained by the layer 2 module 303 to the IP module 305 in the uplink direction, and directly transmits the data, signaling, or information obtained by the IP module 305 to the layer in the downlink direction. 2 module 303.

The following describes the functions of each module in the AP through several typical application scenarios.

During the AP attach procedure, the Ia-g interface module 304 automatically connects to the gateway upon power up. After the Ia-g interface module 304 is connected to the gateway, the layer 2 module 303 accepts the authentication of the gateway, and instructs the Ia-g interface module 304 to establish an interface with the gateway after the authentication is passed, and performs synchronization operation with the gateway after the interface is established. Accept the parameter configuration of the gateway.

In the UE attaching process, the layer 2 module 303 establishes an RRC connection with the UE according to the request of the UE, and requests the gateway to allocate an IP address to the UE after the RRC connection is established, and transmits the allocated IP address to the UE. The RRC part of the layer 2 module 303 is further configured to authenticate the UE, and after the authentication is passed, request the gateway to allocate an IP address to the UE.

In this embodiment, the internal structure and function of the gateway and the AP are improved. In order to better communicate with the network side, the internal structure and function of the UE are also improved accordingly. It is easy to think that the devices in this embodiment are not necessarily required to be implemented, and each of them can be implemented independently.

The physical layer processing module 502 is configured to encode or decode the data signal into a frame, and perform modulation or demodulation. Layer 2 module 503 is used for wireless link control and media access control of data, and for wireless resource control of connection management.

The IP module 504 is configured to perform at least one of the following operations: IP packet encapsulation or decapsulation, IP address allocation, addressing, and Routing, QoS differentiated services, flow control, and statistics.

Preferably, the layer 2 module 503 is directly connected to the IP module 504, and high-level modules such as the PDCP layer module and the NAS layer module are omitted.
