Embodiment 1

[0104] Embodiment 1 of the present invention aims at the situation that the small cell base station does not need to feed back the available range to the macro cell base station after receiving the reserved dual connectivity user identifier value range, see image 3 :

[0105] Step 301: The macro cell base station indicates the reserved dual connectivity user identifier value range to all small cell base stations.

[0106] In this step, the range of dual connectivity user identifier values ​​is determined by the macro cell base station, which is 003D-FFF3 in the embodiment of the present invention, and the macro cell base station assigns this range to all small cell base stations. In the embodiment of the present invention, various information is transmitted between the macro cell base station and the small cell base station through a newly defined signaling message transmitted through the Xn interface. Afterwards, all small cell base stations will no longer allocate C-RNTI v...

Embodiment 2

[0123] Embodiment 2 of the present invention is aimed at the situation where MeNB and SeNB negotiate and jointly determine the range of dual connectivity user identifier values ​​after multiple information exchanges, see Figure 4 :

[0124] Step 401: The macro cell base station indicates the reserved dual connectivity user identifier value range to all small cell base stations.

[0125] In this step, the macro cell base station determines the value range of the dual connectivity user ID. According to the distribution of C-RNTI values ​​in the existing standard, the available range of C-RNTI is: 0001-FFF3. In the embodiment of the present invention, it is set as 003D-FFF3, and the macro cell base station assigns this range to all small cell base stations. In the embodiment of the present invention, information exchange is performed between the macro cell base station and the small cell base station by adding an information element through a newly defined X2 interface.

Abstract

The invention provides a determination method of a cell radio network temporary identification (C-RNTI) of double-connection users, a macrocell base station (MeNB) and small-cell base stations (SeNB). The method comprises the following steps: reserving the range of identification values of the double-connection users; indicating the reserved range of the identification values of the double-connection users to all the small-cell base stations; sending feedbacks about the range of available or unavailable identification values by the small-cell base stations to the macrocell base station, determining the final range of the identification values by the macrocell base station, and indicating the final range of the identification values to relative small-cell base stations by the macrocell base station; receiving an access request sent from the double-connection users; distributing shared double-connection identification values for the double-connection users from the final range of the identification values by the macrocell base station; indicating the distributed double-connection identification values shared by the double-connection small-cell base stations and the macrocell base station. The invention determines that in a double-connection scene, the double-connection users can use the same C-RNTI in the MeNB and the SeNB, and can dynamically arrange the range of the C-RNTI resources according to the number of double-connection users, so that the use ratio of the C-RNTI resources is greatly increased.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for determining a dual connection user ID, a macro cell base station and a small cell base station. Background technique [0002] The dual connectivity technology is introduced for scenarios where the macro cell base station (MeNB) and the small cell base station (SeNB) overlap and use the same or different frequencies; or there is only small cell base station coverage, and the backhaul link between the cells is not ideal. of. Dual connectivity means that the user (UE) is provided with wireless resources by multiple network nodes with unsatisfactory backhaul links, that is, the user has air interface connections with MeNB and SeNB at the same time, which means that MeNB and SeNB can provide services for users at the same time . Since the UE is connected to the MeNB and the SeNB at the same time, when the UE moves inside the base station of the ma...
