Description

Wireless backhaul link assisting establishment method and device, wireless backhaul link establishing method and device

This application claims to be filed on January 16, 2017, the Chinese Patent Office, the application number is 201710032404.2, and the invention is entitled "Wireless backhaul link assisted establishment method and device, wireless backhaul link establishment method and device" Priority is hereby incorporated by reference in its entirety.

Technical field

The present application relates to the field of communications, and in particular, to a wireless backhaul link assisting establishment method and apparatus, and a wireless backhaul link establishing method and apparatus.

Background technique

The elfCell base station is only the size of a business card and is one of the smallest base stations in the world. Due to its small size, it is very convenient for users to carry.

In order to support the elfCell base station to play as you drop, battery power can be used to get rid of the power line, and wireless backhaul can be used to get rid of the base station backhaul line.

One implementation of the wireless backhaul is to insert a SIM card of an operator into the elfCell base station, and access the carrier network based on the SIM card as a wireless backhaul link. However, this approach is subject to certain restrictions. When a user carries an elfCell base station to a different country or region, there may be no network coverage of the operator, resulting in inaccessibility. There may also be other carrier networks that have signed a roaming agreement with the operator, but the cost is higher due to roaming. high.

Another implementation of the wireless backhaul is based on the soft SIM technology, dynamically configuring the locally accessible, lowest cost operator's soft SIM according to the location of the elfCell base station, and providing wireless backhaul based on the soft SIM. A typical flow of the most flexible one of the existing soft SIM solutions is shown in Figure 1.

It can be seen from the process of providing wireless backhaul based on the soft SIM shown in FIG. 1 that the solution determines which soft SIM needs to be downloaded based on the interaction between the terminal and the user, and needs to download the soft SIM based on the existing data channel when downloading the soft SIM. The terminal is the same device as the terminal using the soft SIM.

There is currently no method for providing a wireless backhaul link for a base station using a soft SIM. At the same time, in the existing soft SIM solution, the functional entity (terminal) using the soft SIM needs to have an interaction function with the user to determine which soft SIM needs to be downloaded, and the data to be downloaded based on the functional entity needs to be downloaded. aisle. If the above functions are added to the existing base station in order to enable the base station to support the soft SIM, it is equivalent to integrating a more complex terminal on the base station, which will greatly increase the complexity and cost of the base station.
