Description

Wireless backhaul link assisted establishment method and apparatus

Technical Field

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

Background

The elfCell base station is only business card sized and is one of the smallest base stations in the world. Due to the small volume, the utility model is very convenient for the user to carry and use.

In order to support the elfCell base station to be ready to use (play as you drop) anytime and anywhere, a battery can be used to supply power to get rid of the constraint of a power line, and a wireless backhaul can be used to get rid of the constraint of a base station backhaul line.

One way to implement wireless backhaul is to insert a SIM card of a certain operator into the elfCell base station, and use the SIM card as a wireless backhaul link when the SIM card is inserted into the operator network. However, this approach suffers from certain limitations. When a user carries the elfCell base station to go to different countries or regions, the user may not have the network coverage of the operator, so that the user cannot access the elfCell base station; there are also other operator networks that may have signed a roaming agreement with the operator, but the costs are higher due to roaming.

Another implementation of wireless backhaul is based on soft SIM technology, where the soft SIM of the locally accessible, least-expensive operator is dynamically configured according to the location of the elfCell base station, and the wireless backhaul is provided based on the soft SIM. A typical flow of the most flexible of the existing soft SIM solutions is shown in fig. 1.

As can be seen from the process of providing wireless backhaul based on soft SIM shown in fig. 1, the scheme determines which soft SIM needs to be downloaded based on the interaction between the terminal and the user, and the terminal downloading the soft SIM needs to be based on the existing data channel, and the terminal downloading the soft SIM and the terminal using the soft SIM are the same device.

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