Problems solved by technology

[0003] However, although the silent redial function can solve the call failure problem before the QCI 1 dedicated load is established, the process has a long delay. After the MO terminal dials, after 6 seconds of no response time, it turns to trigger the CSFB process. After a long period of Evolution (LTE, Long Term Evolution) live network measurement, the CSFB process takes 7 seco

Embodiment 1

[0040] An embodiment of the present invention provides a scheduling method. figure 2 It is a schematic flow chart of the scheduling method of the embodiment of the present invention; as figure 2 As shown, the method includes:

[0041] Step 201: the base station obtains a first characteristic parameter representing uplink interference.

[0042]Step 202: When the first characteristic parameter is greater than the first threshold, the control is switched from the normal state to the interference avoidance state.

[0043] Step 203: In the interference avoidance state, monitor whether there is a scheduling request of the user on the first specific bearer.

[0044] Step 204: When there is a scheduling request of the user on the first specific bearer, determine the uplink resources of the scheduling request, and send the uplink resources to other base stations except the base station, so that the other base stations avoid Use the uplink resource.

[0045] In this embodiment, th...

Embodiment approach

[0049] As an implementation manner, the method further includes: when there is no scheduling request of the user on the first specific bearer, not executing the uplink avoidance scheme and maintaining a normal state.

[0050] In this embodiment, when no data transmission of the user is detected on the second specific bearer, the uplink resources of the scheduling request are determined again, and the uplink resources are sent to other base stations except the base station, so as to causing the other base stations to avoid using the uplink resource; until it is detected that there is data transmission of the user on the second specific bearer. Wherein, the second specific bearer is a bearer that does not need to be enhanced. The second specific bearer may be, for example, a QCI 1 bearer.

[0051] Specifically, when the base station monitors the data transmission of the user (the user is specifically the user scheduled on the first specific bearer) on the QCI 1 bearer, it indic...

Embodiment 2

[0062] The embodiment of the present invention also provides a base station. Figure 5 It is a schematic diagram of the composition and structure of the base station of the embodiment of the present invention; Figure 5 As shown, the base station includes: an acquisition unit 41, a control unit 42, a monitoring unit 43 and a communication unit 44; wherein,

[0063] The obtaining unit 41 is configured to obtain a first characteristic parameter representing uplink interference;

[0064] The control unit 42 is configured to switch from the normal state to the interference avoidance state when the first characteristic parameter obtained by the acquisition unit 41 is greater than a first threshold;

[0065] The monitoring unit 43 is configured to monitor whether there is a scheduling request of the user on the first specific bearer in the interference avoidance state; when there is a scheduling request of the user on the first specific bearer, determine the scheduling request of t...

Abstract

The embodiment of the invention discloses a scheduling method and a base station. The method comprises the steps that the base station obtains a first characteristic parameter for representing uplinkinterference; when the first characteristic parameter is greater than a first threshold, a normal state is switched to an inference avoidance state; whether a scheduling request of a user exists on afirst specific bearer or not in the inference avoidance state; and when the scheduling request of the user exists on the first specific bearer, an uplink resource of the scheduling request is determined, and the uplink resource is sent to another base station except the base station, so the another base station avoids the usage of the uplink resource.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a scheduling method and a base station. Background technique [0002] During the call initiation process of the IMS-based voice service (VoLTE, Voice over LTE), due to interference problems, there is a possibility of call initiation failure. The solution in the prior art is to use the silent redial function. When the uplink terminal (MO, MobileOriginal) does not receive the 100trying feedback message for the Invite message for more than 6 seconds after sending the Invite message, or the MO does not complete the QCI ( When the QoS Class Identifier) ​​1 dedicated load is established, an ESR (Extended Service Request) message is sent to trigger a circuit switched fallback (CSFB, Circuit Switched Fallback), and a circuit switched (CS, Circuit Switched) domain call is re-initiated after falling back to 2G. [0003] However, although the silent redial function can solve the call fa...
