Problems solved by technology

[0003] At present, the speed of high-speed trains is fast, and the maximum speed can reach 310 km / h. The TD-LTE network adopts F-band or D-band networking. Due to the high frequency of F-band or D-band, the penetration loss is large, and most sites share the second 2G, 2nd generation) network physical sites (planned according to 900M frequency), resulting in weak coverage before some TD-LTE sites, and in the high-speed operation mode, the Doppler frequency deviation in the high frequency band is more obvious, It is required that the terminal chip has a strong ability to correct the frequency offset, otherwise it is very easy to leave the private network. Since there is no neighbor relationship between the high-speed rail private network and the public network, users who have left the private network cannot return to the high-speed rail private network and stay on the public network. , user perception is extremely poor

Embodiment 1

[0049] figure 1 The realization flowchart of the private network user resident method provided by the present invention, such as figure 1 As shown, the private network user resident method mainly includes the following steps:

[0050] Step 101: Obtain mobile information of the terminal; wherein, the mobile information includes information of cells where the terminal has camped.

[0051] In this embodiment, the private network refers to a communication network established to ensure the communication of terminals located on fast-moving motor vehicles, such as a high-speed rail private network, a bullet train private network, a maglev train private network, and the like.

[0052] Preferably, the acquiring the mobile information of the terminal may include:

[0053]Counting user information of terminals accessing the indoor sub-cell in the first area, and transferring the user information to the private network cell in the second area;

[0054] When the terminal accesses the pr...

Embodiment 2

[0083] figure 2 A flow chart of realization of LTE private network user residency under the high-speed rail scene provided by the present invention, such as figure 2 As shown, the process mainly includes:

[0084] Step 201: Find and lock the terminal of the 4G user.

[0085] Step 202: Determine whether the terminal is a high-speed rail user, if yes, execute step 203; otherwise, return to step 202.

[0086] Specifically, the specific steps of judging whether the terminal is a high-speed rail user may include:

[0087] Count the user information of the terminals connected to the sub-districts of the waiting room in the high-speed railway station, and transmit them to the high-speed rail platform private network community through the X2 interface at a certain time interval;

[0088] When the terminal enters the private network community of the high-speed rail platform, and the terminal resides in the sub-district of the waiting room, the private network community of the plat...

Embodiment 3

[0117] Figure 5 A schematic diagram of the composition and structure of the private network user resident device provided by the present invention, such as Figure 5 As shown, the device includes: an acquisition unit 51, a judgment unit 52, an allocation unit 53, and a delivery unit 54; wherein,

[0118] The obtaining unit 51 is configured to obtain mobile information of the terminal; wherein the mobile information includes cell information where the terminal has camped;

[0119] The judging unit 52 is configured to judge whether the terminal is a dedicated network user based on the mobile information;

[0120] The allocation unit 53 is configured to allocate a private network user identifier and private network frequency point information to the terminal if the judging unit determines that the terminal is a private network user;

[0121] The sending unit 54 is configured to send the private network user identifier and the private network frequency point information to the ...

Abstract

The invention discloses a private network user residing method. The method comprises the following steps: acquiring movement information of a terminal, wherein the movement information includes information of a cell in which the terminal resides before; judging whether the terminal is a private network user or not according to the movement information; if so, allocating a private network user identifier and private network frequency point information to the terminal; and issuing the private network user identifier and the private network frequency point information to the terminal, so that the terminal resides in a private network based on the private network user identifier and the private network frequency point information. Meanwhile, the invention discloses a private network user residing device. Through adoption of the technical scheme of the invention, the residing capability of the terminal in the private network can be improved, and the use experience of the user is improved.

Description

technical field [0001] The invention relates to wireless technology, in particular to a method and device for private network user camping. Background technique [0002] In order to speed up the rapid development of high-speed rail trunk lines, many provinces and cities have deployed multiple physical Time Division Long Term Evolution (TD-LTE, Time Division Long Term Evolution) base stations around high-speed rail trunk lines to achieve full TD-LTE private network coverage, which is convenient for users in the Browsing the web, watching videos, online shopping, financial investment, etc. on the high-speed rail will enhance users' user perception on the high-speed rail. [0003] At present, the speed of high-speed trains is fast, and the maximum speed can reach 310 km / h. The TD-LTE network adopts F-band or D-band networking. Due to the high frequency of F-band or D-band, the penetration loss is large, and most sites share the second 2G, 2nd generation) network physical sites...
