Example Embodiment

[0066] Example 1:

[0067] see image 3 , image 3 A schematic diagram of a scene of paging interference between a macro base station and a pico base station provided in the first embodiment.

[0068] like image 3 As shown, the macro base station and the pico base station exist in the heterogeneous network at the same time. Wherein, the macro base station determines that the user terminal in the connected state in its coverage area is a UE, and the UE is interfered by the paging of the pico base station, that is, the macro base station serves as the first base station, and the pico base station serves as the second base station.

[0069] Assuming that the paging parameter nB=T pre-configured by the macro base station, the actual paging cycle of the UE is T, and the equivalent identifier of the UE is UE_ID, then the macro base station knows that N=T (N takes the minimum value between T and nB), And substituting N=T into the above formula (2), calculate the set of paging fr...

Example Embodiment

[0073] Embodiment 2:

[0074] see Figure 4 , Figure 4 A schematic diagram of a scene of paging interference between a macro base station and a pico base station provided in the second embodiment.

[0075] like Figure 4 As shown, the macro base station and the pico base station exist in the heterogeneous network at the same time. Wherein, UE1 and UE2 in the connected state in the pico base station are UE1 and UE2, and UE1 and UE2 are interfered by the paging of the macro base station, that is, the pico base station serves as the first base station, and the macro base station serves as the second base station.

[0076] Assuming that the paging parameter nB pre-configured by the pico base station is 2T, the actual paging period T of UE1 and UE2 is 640ms, and the equivalent identifiers UE_ID of UE1 and UE2 are 12 and 37 respectively, then the pico base station knows that N=T( N takes the minimum value between T and nB), for UE1, the pico base station can substitute N=T and ...

Abstract

The embodiment of the invention, which relates to the communication technology field, discloses a paging resource coordination method in a heterogeneous network (HN) and a system thereof, and a base station. The paging resource coordination method comprises the following steps that: a first base station determines user equipment (UE) that is in a connected state; the first base station calculates a number of a subframe that is used for sending paging information and a frame number of a paging frame that the subframe belongs to, wherein the paging information is used for carrying out paging on the UE that is in a connected state; and the first base station sends the calculated subframe number and the calculated frame number of the paging frame to a second base station, so that the second base station configures the subframe that is corresponded to the subframe number in the paging frame that is corresponded to the frame number into an almost blank subframe or the second base station stops to send information on the subframe that is corresponded to the subframe number in the paging frame that is corresponded to the frame number. According to the embodiment of the invention, paging interference on UE that is in a connected state in an HN can be avoided; and wasting of resources of an interfered cell can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for coordinating paging resources in a heterogeneous network, a base station and a system. Background technique [0002] In a long term evolution (Long term evolution, LTE) wireless communication system, a macro base station and a low power base station can be deployed simultaneously in the same network cell, and this network is called a heterogeneous network (Heterogeneous Network, HN). Wherein, the low-power base station may include but not limited to a micro base station, a pico base station, and a relay station. Low-power base stations can be used to cover hot spots, indoors, blind spots or cell edges of cells, and can improve the average throughput of cells and the throughput of cell edges. In a heterogeneous network, in order to improve the spectrum utilization efficiency of the system as much as possible, the macro base station and the low-power base stati...
