Embodiment 1

[0054] This embodiment provides a paging method for a heterogeneous network, which can be used in a heterogeneous network to prevent the offending cell from interfering with the user equipment (UE) of the victim cell, making it impossible to receive paging messages, such as figure 2 As shown, the method includes:

[0055] Step S1, when the user equipment meets the interference reporting condition, report the interference report to the base station belonging to the victim cell, so that the base station belonging to the victim cell can generate and deliver a paging configuration update message according to the received interference report;

[0056] In the above step S1, the conditions for the user equipment to meet the interference report include: when it is detected that the interference value exceeds the preset threshold; or, there is an abnormal reception of the paging message; or, the preset interference reporting time reaches the set periodic reporting time . If any one o...

Embodiment 2

[0069] This embodiment provides a paging method for a heterogeneous network, which is basically the same as the method given in Embodiment 1, except that (see image 3 ): before the user equipment sends the interference report, the method further includes a step S0 of receiving a preset paging configuration issued by a broadcast message from the base station to which the victim cell belongs, and the preset paging configuration includes avoiding Interfering paging configuration.

[0070] The above preset paging configuration may be a paging configuration pre-negotiated by the base station of the victim cell and the base station of the offending cell. Under normal conditions, each paging configuration is a low-interference paging configuration. If one or several If a paging configuration enters a high-interference state, the paging configuration that does not receive high interference is a paging configuration that avoids high interference.

[0071] In the above method, in the ...

Embodiment 3

[0075] This embodiment provides a paging method for a heterogeneous network, which can be used in a heterogeneous network to prevent the offending cell from interfering with the user equipment (UE) of the victim cell, making it impossible to receive paging messages, such as Figure 4 As shown, the method includes:

[0076] Step S11, the base station of the victim cell receives the interference report reported by the user equipment when the interference reporting condition is met, generates a paging configuration update message according to the received interference report, and sends the paging configuration update message to the user Device delivery;

[0077] In the above step S11, generating the paging configuration update message according to the received interference report specifically includes the following methods:

[0078] The first way to generate a paging configuration update message is: if the base station to which the victim cell belongs has not negotiated with the...

Abstract

The embodiment of the invention provides a method, a device and a system for paging a heterogeneous network, which belongs to the communication field. The method comprises the following steps: reporting an interference report to a base station in which an interfered cell resides when the condition of reporting interference is satisfied so that the base station in which the interfered cell resides can generate and send a paging configuration updating message according to the received interference report; and receiving the paging configuration updating message generated and sent by the base station in which the interfered cell resides, and updating the paging configuration to the paging configuration which can avoid the interference according to the paging configuration updating message. The invention further provides a terminal device, a communication device and a communication system. In the scene of the heterogeneous network, under the condition that the interfering cell configures is approximately configured with vacant sub-frame so as to ensure the load thereof and reduce the signaling overload on the interface at the rank of the cell (or base station), the interfered UE (User Equipment) in the interfered cell can also receive the paging message through the method.

Description

technical field [0001] The present invention relates to the communication field, in particular to a paging method, equipment and system for a heterogeneous network. Background technique [0002] In the current LTE (Long Term Evolution, long-term evolution) heterogeneous network, small base stations are placed within the coverage of the macro base station (Macro eNB), such as Pico, HeNB (Home eNB, home base station), Femto, Relay and other wireless access points , UE (User Equipment, user equipment (terminal)) is under the dual coverage of macro base stations and small base stations. The maximum capacity that this system can obtain is the sum of the capacities of macro base stations and small base stations. The station network has a higher capacity. In scenarios such as office buildings, shopping malls, and campus networks, the heterogeneous deployment of these small base stations and macro base stations can effectively enhance network coverage and improve spectrum efficienc...
