Problems solved by technology

[0014] But its disadvantages are: Femto home base station is not optimized for the characteristics of indoor data services. Taking LTE as an example, the LTE Femto system basically adopts the complete protocol architecture and interface design of LTE, so the implementation is complicated, but the capacity and power of the base station are reduced. Therefore, the cost remains high;
[0015] In addition, Femto is a device in the IMT (International Mobile Telecommunications, International Mobile Telecommunications) system, and its working frequency is still the operator's authorized frequency band in IMT. Compared with WiFi, the available bandwidth is less, and it cannot fully meet the operator's data service distribution. need

Embodiment 1

[0281] This embodiment is used to illustrate the implementation of the access and communication process of the NDA terminal.

[0282] The process of NDA terminal access and communication can be as follows:

[0283] The NDA base station equipment starts up, completes the connection and communication process with the NDA gateway and the LTE core network, and completes the parameter configuration.

[0284] In a specific implementation, in order to avoid interference with the cellular network formed by the LTE base station as much as possible, different frequency bands where the NDA base station works can be configured. Of course, it can also work in the same frequency band.

[0285] The NDA base station transmits synchronization signals according to the protocol, and configures various control channels. In specific implementation, the capability attribute of the base station can also be marked as NDA mode in the system broadcast configuration information.

[0286] The NDA termi...

Embodiment 2

[0291] This embodiment is used to illustrate the implementation of the access and communication process of the LTE+NDA terminal.

[0292] The access and communication process of the LTE+NDA terminal can be as follows:

[0293] The NDA base station equipment starts up, completes the connection and communication process with the NDA gateway and the LTE core network, and completes the parameter configuration.

[0294] The LTE base station equipment starts up, completes the corresponding connection configuration and communication process, and completes the parameter configuration.

[0295] In a specific implementation, in order to avoid interference with the cellular network formed by the LTE base station as far as possible, the NDA base station is configured in a different frequency band. Of course, it can also work in the same frequency band under the premise of meeting certain radio frequency indicators.

[0296] The NDA base station transmits synchronization signals accordin...

Embodiment 3

[0302] This embodiment is used to illustrate the implementation manner of the LTE+NDA terminal switching process between the two modes.

[0303] The LTE+NDA terminal works in the LTE base station equipment according to the LTE mode;

[0304] The terminal performs neighbor cell measurement and reports, by reading the neighbor cell broadcast, or detecting that a handover target cell is an NDA cell in the attribute of the neighbor cell;

[0305] The LTE base station judges that the handover target cell of the terminal is an NDA cell through handover;

[0306] The terminal and the network side maintain the high-level data connection, and suspend the sending and receiving of data;

[0307] The terminal disconnects the wireless connection with the LTE base station and switches it to NDA mode;

[0308] The terminal completes synchronization and access to the new NDA cell, and establishes a wireless connection;

[0309] The terminal and the network continue to send and receive data...

Abstract

The invention discloses a method and a device for wireless data access. The method comprises the following steps: a mobile terminal transmits / receives data from / to a wireless access network device, wherein IP packet segmentation processing is performed on the data before data is transmitted according to 3GPP protocol through a radio frequency module, and the said data is the data in the data service; the wireless access network device receives the data transmitted by the wireless terminal through air interface according to 3GPP LTE protocol when receiving a data service request initiated by the wireless terminal, encapsulates the received data into IP packets, and transmits the packets to the Internet and / or a core network through data transmission interface. The invention provided by the invention can satisfy indoor and hotspot wideband wireless data requirements and effectively reduce cost overhead of data service, and provides telecommunication providers with a low-cost manner to split data service.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a wireless data access method and equipment. Background technique [0002] In recent years, with the popularity of the mobile Internet (Mobile Internet) and smart phones, the demand for mobile data traffic has grown rapidly. figure 1 It is a schematic diagram of global data traffic forecast results. After Cisco (Cisco) forecasted mobile data traffic traffic from 2009 to 2014, it found that, as figure 1 As shown, from 2009 to 2014, traffic increased by 40 times, basically doubling every year. [0003] figure 2 It is a schematic diagram of the growth of data services and the growth trend of operators' revenue. At present, the proportion of data services in operators' networks is gradually increasing, which has affected traditional carrier-class services. However, if figure 2 As shown, since the data service is billed according to the flow rate, its profit growth rat...
