Embodiment 1

[0050] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a subframe ratio adjustment method according to the present disclosure, which may specifically include the following steps:

[0051] Step 101, determine the service type of the mobile terminal in the cell.

[0052] Among them, the service type includes data service and voice service. Among them, the service type is data service, which means that the mobile terminal is accessing network data, for example, accessing web pages through a browser, instant messaging through social applications, etc.; the service type is voice service , representing that the mobile terminal is using a VOLTE (Voice Over Long Term Evolution, voice over long term evolution) service.

[0053] It can be understood that in practical applications, when a mobile terminal requests service data transmission, it will first send a service request to the base station, carrying the service type, and the base station can record the...

Embodiment 2

[0073] refer to figure 2 , which shows a flow chart of steps in Embodiment 2 of a subframe ratio adjustment method according to the present disclosure, which may specifically include the following steps:

[0074] Step 201, determine the service type of the mobile terminal in the cell.

[0075] For this step, reference may be made to the detailed description of step 101, which will not be repeated here.

[0076] Step 202, if the service type is a data service, determine whether the mobile terminal supports FDD communication.

[0077] For this step, reference may be made to the detailed description of step 102, which will not be repeated here.

[0078] Step 203: If the mobile terminal supports FDD communication, determine whether there is an FDD cell corresponding to the same BBU as the current TDD cell where the mobile terminal is located.

[0079] For this step, reference may be made to the detailed description of step 103, which will not be repeated here.

Embodiment 3

[0107] refer to image 3 , which shows a structural block diagram of a third embodiment of a base station according to the present disclosure, which may specifically include the following modules:

[0108] The service type determination module 301 is configured to determine the service type of the mobile terminal in the cell.

[0109] The FDD communication determination module 302 is configured to determine whether the mobile terminal supports FDD communication if the service type is a data service.

[0110] The FDD cell determination module 303 is configured to determine whether there is an FDD cell corresponding to the same BBU as the current TDD cell where the mobile terminal is located if the mobile terminal supports FDD communication.

[0111] The FDD cell switching module 304 is configured to switch the mobile terminal from the current TDD cell to the FDD cell if there is an FDD cell corresponding to the same BBU as the current TDD cell where the mobile terminal is loca...

Abstract

Embodiments of the present disclosure provide a subframe ratio adjustment method and a base station, wherein the method includes: determining the service type of a mobile terminal in a cell; if the service type is a data service, determining whether the mobile terminal supports FDD communication; if the mobile terminal supports FDD communication, determine whether there is an FDD cell corresponding to the same BBU as the current TDD cell where the mobile terminal is located; if there is an FDD cell corresponding to the same BBU as the current TDD cell where the mobile terminal is located cell, handover the mobile terminal from the current TDD cell to the FDD cell; adjust the subframe ratio of the TDD cell. The embodiment of the present disclosure can switch the mobile terminal in the TDD cell to the FDD cell before adjusting the subframe ratio, which helps to avoid service interruption of the mobile terminal caused by the adjustment of the subframe ratio.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a subframe ratio adjustment method and a base station. Background technique [0002] In an LTE TDD (Long Term Evolution Time Division Dual, Long Term Evolution Time Division Duplex) network, uplink and downlink data are transmitted on different subframes. Since the data volume of the uplink and downlink services will change dynamically, the subframe ratio used to control the uplink and downlink data can be dynamically adjusted. [0003] In the prior art, after the base station side dynamically adjusts the subframe ratio, two schemes are used to make the adjusted subframe ratio take effect: first, all terminals in the cell are deactivated and reattached to the terminal after reactivation. Process; second, for mobile terminals in the idle state, the base station will send a paging message to notify the mobile terminal to re-read the new subframe configuratio...
