Embodiment Construction

[0024] The specific embodiments of the present invention will be described below with an LTE system. However, the method of the present invention is by no means limited to the LTE system, and can also be applied to the HNB access system in the 3G (UMTS) system and the HNB access system of the future mobile communication system.

[0025] Embodiment 1 of the present invention is as follows figure 2 shown. In this embodiment, the HNB access system may include the HNB, or the HNB and the HNB GW. Corresponding to the solution in which the HNB access system includes the HNB and the HNB GW, the point of direct communication is the HNB. The functions of the HNB GW include forwarding messages between the HNB and the MME, and responsible for the mobility management of the UE within the control range of the HNB GW.

[0026] The network (such as the operation and maintenance center (hereinafter referred to as OMC)) allocates an identifier GII that can uniquely identify the UE in the g...

Abstract

A method of user equipment for direct communication through a HNB access system, comprises that: a first user equipment UE having a unique identification GII in a closed subscriber group CSG initiates calling request to a second user equipment UE belonging to the same CSG, informs the unique identification GII of the second user equipment of the HNB access system if the first user equipment and the second user equipment are in the same HNB access system, the HNB access system builds communication burdening passing through the HNB access system for the two user equipment. According to the method for direct communication through the HNB access system of the user equipment provided by the invention, transmission efficiency of applying HNB is increased, network resource is saved.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method for enabling two UEs to communicate directly through the HNB access system when both user equipments (hereinafter referred to as UEs) are under a home base station (hereinafter referred to as HNB) access system. Background technique [0002] The system structure of SAE is as follows figure 1 shown. Below is the figure 1 Description of the SAE system structure. [0003] 101 User equipment (hereinafter referred to as UE) is a terminal device used to receive data. 102EUTRAN is the wireless access network in the evolved system SAE, also called ENB, which is responsible for providing the LTE mobile phone with an interface to access the wireless network, and is connected with the mobile phone's mobility management entity 103MME and the user plane entity 104 Serving Gateway through the S1 interface. The 103MME is responsible for managing the mobile context and ses...
