DETERMINING HANDOVER PARAMETERS

Abstract

In some examples, to mitigate interference of wireless communications, an electronic device that includes a first type wireless component and a second type wireless component receives values of parameters relating to wireless communication using the first type wireless component. The electronic device determines, using a model of a relationship between the parameters relating to wireless communication using the first type wireless component and at least one handover parameter relating to wireless communication using the second type wireless component, a value of the at least one handover parameter based on the received values of the parameters relating to wireless communication using the first type wireless component. It is determined whether the electronic device should be handed over from a first access point to a second access point based on the determined value of the at least one handover parameter.

DETAILED DESCRIPTION

FIG. 1 is a block diagram of an example arrangement that includes an electronic device 100 and multiple access points (APs) 102, 104. Examples of the electronic device 100 can include a computer (e.g., a desktop computer, a notebook computer, a tablet computer, etc.), a mobile phone, a personal digital assistant, a game appliance, a wearable device (e.g., a smart watch, smart eyeglasses, a head-mounted device, etc.), a sensor device, and so forth.

An AP can refer to a communication device to which a wireless device can establish a wireless connection to communicate with other endpoint devices. An AP can be part of a wireless local area network, which operates according to the Institute of Electrical and Electronic Engineers (IEEE) 802.11 or Wi-Fi Alliance Specifications. In other examples, a WLAN can operate according to other protocols. More generally, techniques or mechanisms according to some implementations of the present disclosure can be used with other types of wireless networks, such as cellular networks or other wireless networks. In a cellular network, an AP can refer to a wireless access network node, such as a base station or enhanced node B (eNodeB) in a cellular network that operates according to the Long-Term Evolution (LTE) standards as provided by the Third Generation Partnership Project (3GPP). The LTE standards are also referred to as the Evolved Universal Terrestrial Radio Access (E-UTRA) standards.

The electronic device 100 includes a wireless communication component 106 that is able to establish wireless connections with any one or more of the APs 102, 104. Although just two APs 102, 104 are depicted in FIG. 1, it is noted that in other examples, more APs 102, 104 can be provided. Establishing a wireless connection with an AP can refer to setting up or otherwise providing resources associated with the AP that are used to carry control and data traffic between the electronic device and the AP.

The electronic device 100 can also include an interference source 108 that can interfere with wireless communications of the wireless communication component 106. The interference source 108 can be another wireless communication component that is able to communicate wirelessly, which can be according to a protocol different from that used by the wireless communication component.

The interference source 108 can be considered a first type wireless communication component, and the wireless communication component 106 can be considered a second type wireless communication component. Wireless communication components are of different types if they use different protocols to perform wireless transmissions and receptions of control and data signaling. More generally, a wireless communication component can refer to any communication interface (in the form of a hardware transmitter and receiver and possibly program code) that is able to communicate wireless signals over a communication medium.

As further examples, although the interference source 108 is shown as being part of the electronic device 100, it is possible that interference with the wireless communication component 106 can be caused by an interference source that is external of the electronic device 100. For example, the interference source can be part of another electronic device that is near the electronic device 100.

As examples, the wireless communication component 106 can include a radio frequency (RF) transceiver to perform RF communications. One type of RF transceiver is a WLAN transceiver that operates according to the IEEE 802.11 protocol.

The interference source 108 can include another RF transceiver, such as an RF transceiver for communicating with a cellular network (e.g., an LTE network), a Bluetooth transceiver, a Global Positioning System (GPS) transceiver, an RF transceiver for performing communication of wireless high-definition audio and video signals, a frequency modulation (FM) radio transceiver, and so forth. Although just one interference source 108 is shown, there can be multiple interference sources either inside the electronic device 100 or outside the electronic device 100, or both.

Interference caused by an internal and/or external interference source can cause desense of the wireless communication component 106. Desense of the wireless communication component 106 can refer to a degradation in sensitivity of the wireless communication component 106 for wireless communications, which can lead to increased error rates or service interruption.

To address desense of the wireless communication component 106 due to presence of an interference source, the electronic device 100 includes interference mitigation logic 110, which is shown as being part of handover logic 112 in the example of FIG. 1. The interference mitigation logic 110 responds to detected interference with the wireless communication component 106 by triggering an action to mitigate the detected interference. The handover logic 112 controls handover of the electronic device 100 between the APs 102 and 104. Handing over the electronic device 100 from a first AP to a second AP refers to causing the electronic device 100 to transition from communicating over a wireless connection with the first AP (source AP) to communicating over a wireless connection with the second AP (destination AP). An action that can be triggered by the interference mitigation logic 110 is handover of the electronic device 100 between APs when interference is detected, to mitigate an effect of the interference. In a WLAN, handover of the electronic device 100 can refer to performing a basic service set (BSS) transition of an electronic device between WLAN APs.

The different APs can be associated with different communication channels, which can be distinguished by different frequencies, or different time slots, or different codes, or some combination of the foregoing. Different APs can refer to different physical APs that are located at geographically separate locations. In other examples, different APs can refer to different logical APs, where two or more of the logical APs can reside at a common physical platform.

The electronic device 100 also includes a wireless connection quality detector 114, which is able to monitor the quality of wireless communications performed by the wireless communication component 106.

Each of the handover logic 112, interference mitigation logic 110, and wireless connection quality detector 114 can be implemented with a hardware processing circuit, or as a combination of machine-readable instructions and a hardware processing circuit. Examples of a hardware processing circuit can include any or some combination of the following: a microprocessor, a core of a multi-core microprocessor, a digital signal processor, a microcontroller, a programmable gate array, a programmable integrated circuit device, or any other type of hardware processing circuit.

The wireless connection quality detector 114 is able to monitor the quality of both uplink and downlink communications between the electronic device 100 and an AP to which the electronic device 100 is currently connected. In some examples, monitoring the quality of a downlink (that carries signals from the source AP to the electronic device 100) can be based on monitoring a received signal strength indicator (RSSI) transmitted by the source AP. RSSI is a measurement of the power present in a received radio signal. In some examples, the higher the RSSI value, the stronger the received radio signal. In other examples, other indicators of the quality of downlink communications can be employed, such as a detected data rate over the downlink, or another indicator.

An example of the quality of an uplink that can be monitored includes an indicator of a transmission retry rate in the uplink. The transmission retry rate refers to a number of retries performed by the wireless communication component 106 on the uplink within a certain time interval. A “retry” can refer to retransmission of data (control data or bearer traffic data) due to corruption of the data or inability of a receiver to successfully receive the data. In other examples, other indicators of the quality of the uplink can be employed, such as a data rate of the uplink.

Information relating to the monitored quality of the wireless connection (uplink or downlink or both) is provided by the wireless connection quality detector 114 to the interference mitigation logic 110. Based on the monitored quality of the wireless connection and handover control parameters 116 (or more simply, “handover parameters”), the interference mitigation logic 110 can decide whether or not to perform a handover of the electronic device 100 from the source AP to a destination AP that is different from the source AP. As noted above, the source AP and the destination AP can include different physical APs, or different logical APs. Handing over the electronic device 100 from the source AP to the destination AP can also refer to causing the electronic device 100 to transition from one communication channel to another communication channel.

In examples where values of the handover control parameters 116 are statically set, the statically set values of the handover control parameters 116 can assume the worst case in terms of interference, i.e., the values of the handover control parameters 116 were determined when an interference source (e.g., 108) caused the most severe interference with the wireless communication component 106. However, making a handover decision based on use of such worst case handover control parameters 116 can result in sub-optimal performance of the electronic device 100, especially under conditions where the interference caused by an interference source is not the worst case interference.

In accordance with some implementations of the present disclosure, the handover control parameters 116 that are provided to the interference mitigation logic 110 are dynamically determined by a processor using a model 118, which can be implemented as a lookup table or a function that produces an output based on an input. The model 118 represents a relationship between parameters relating to wireless communication using a first type wireless communication component (e.g., the interference source 108) and handover control parameters relating to wireless communications using a second type wireless communication component (e.g., the wireless communication component 106). For example, the first type wireless communication component can be a cellular network wireless communication component to communicate over a cellular network, such as an LTE network or other type of cellular network. The second type wireless communication component 106 can be a wireless communication component to communicate over a WLAN that operates according to IEEE 802.11.

Although reference is made to specific examples of specific types of wireless communication components, it is noted that in other examples, other types of wireless communication components can be employed.

In accordance with some implementations of the present disclosure, the model 118 is used to predict values of the handover control parameters 116 (for controlling handover between APs that the electronic device 100 can communicate with using the second wireless communication component 106) based on values of parameters relating to wireless communication using the first type wireless communication component (e.g., the interference source 108). Thus, as the values of the parameters relating to wireless communication using the first type wireless communication component change, the model 118 outputs changed values of the handover control parameters 116. Thus, in some examples, based on the status of wireless communication of the interference source 108 (as represented by the values of the parameters relating to wireless communication using the interference source 108), values of the handover control parameters 116 for controlling handover between WLAN APs can be predicted. Such predicted values are more optimal than worst case values of the handover control parameters 116 that assume worst case interference by the interference source 106.

Examples of parameters relating to wireless communication using the first type wireless communication component (e.g., the interference source 108) can include any or some combination of the following: a frequency of the wireless communication, a frequency bandwidth of the wireless communication, a transmit power used by the first type wireless communication component, amount of resources for the wireless communication, how often the resources are available, and so forth. Although specific parameters are listed, it is noted that in other examples, other or additional parameters can be used.

The parameters relating to wireless communication using the first type wireless communication component may be received from a wireless access network node, such as that of a cellular network.

FIG. 2 is a flow diagram of a process that can be performed by the electronic device 100, such as by the handover logic 112 and the interference mitigation logic 110. The process of FIG. 2 receives (at 202) values of parameters relating to wireless communications using the first type wireless communication component (e.g., the interference source 108).??

The process of FIG. 2 further includes determining (at 204), using a model (e.g., 118) of a relationship between the parameters relating to wireless communication using the first type wireless communication component and at least one handover control parameter (e.g., 116) relating to wireless communication using the second type wireless communication component (e.g., the wireless communication component 106), a value of the at least one handover control parameter based on the received values of the parameters relating to wireless communication using the first type wireless communication component.

The process of FIG. 2 further includes determining (at 206) whether the electronic device 100 should be handed over from a first AP to a second AP based on the determined value of the at least one handover control parameter. The determination of whether the electronic device 100 should be handed over from the first AP to the second AP is based on a relationship between a monitored quality of the wireless connection with the first AP and the determined value of the at least one handover parameter (e.g., the monitored quality of the wireless connection being less than a quality threshold).

In some examples, the handover control parameters 116 can include the following: a wireless connection quality threshold (RoamTrigger) and a difference parameter (Δ). In other examples, other or additional handover control parameters can be used.

When the quality indication provided by the wireless connection quality detector 114 (FIG. 1) indicates that the quality of a specific wireless connection (downlink or uplink or both) has dropped below a specified threshold (RoamTrigger), the interference mitigation logic 110 can make the determination of whether or not to perform handover of the electronic device 100 between APs. As examples, if an RSSI detected by the wireless connection quality detector 114 has dropped below a specified RSSI threshold, or a transmission retry rate detected by the wireless connection quality detector 114 exceeds a transmission retry rate threshold, or a data rate detected by the wireless connection quality detector 114 drops below a data rate threshold, then that is an indication that the wireless connection is exhibiting low quality due to interference experienced by the wireless communication component 106.

In the ensuing discussion, it is assumed that the quality indication provided by the wireless connection quality detector 114 is an RSSI value. Similar techniques can be applied to other types of quality indications.

In some examples, if a detected RSSI drops below a quality threshold (RoamTrigger), which can be expressed in dBm (decibel-milliwatts), then a determination of whether handover is to be performed from the source AP to a given destination AP is based on a further handover control parameter A, which represents the difference between the RSSI value of the source AP and a minimum RSSI value that the given candidate destination AP should satisfy:

Δ=sRSSI−mRSSI+b,

where sRSSI is the RSSI value of the source AP measured by the wireless connection quality detector 114, mRSSI is the minimum RSSI value that the given candidate destination AP should satisfy, and b is a specified constant (e.g., between 2 to 5 dBm) to prevent a ping-pong effect that can cause the electronic device 100 to handover between APs too frequently. The mRSSI value is used to specify that the destination AP should not have too low an RSSI (and thus too low wireless connection quality), as compared to the detected RSSI of the source AP.

The parameters RoamTrigger (RSSI threshold) and Δ are examples of the handover control parameters 116 relating to controlling handover between APs that are used in the process of FIG. 2.

In some examples, the roaming condition to trigger a handover from a source AP to a destination AP can be written as follows:

(cAP is available)& (sRSSI<RoamTrigger)&(cRSSI>sRSSI+Δ)  (Eq. 1)

Eq. 1 specifies that a handover from a source AP to a candidate destination AP (“cAP”) is to be triggered if the candidate destination AP is available, and the RSSI of the source AP (sRSSI) is less than RoamTrigger, and the RSSI of the candidate destination AP (cRSSI) exceeds the RSSI of the source AP (sRSSI) by greater than Δ.

In accordance with some implementations, the model 118 (FIG. 1) is used to compute the handover control parameters Δ and RoamTrigger, which can be written in a vector notation as follows:

$\begin{array}{cc}{P}_r=\left(\begin{array}{c}\Delta \\ \mathrm{RoamTrigger}\end{array}\right).& \left(\mathrm{Eq}.2\right)\end{array}$

As noted above, the values of the handover control parameters Δ and RoamTrigger for wireless communication using the second type wireless communication component 106 can be affected by values of parameters relating to wireless communication using the first type wireless communication component (e.g., the interference source 108), which in some examples can be a cellular network wireless communication component. The parameters relating to wireless communication using the cellular network wireless communication component can include the following:

• • FREQ: frequency band of the cellular network;
  • FBW: frequency bandwidth, which refers to a width of a carrier;
  • TxPwr: transmit power;
  • nRB: number of resource blocks used on the downlink from a wireless access network node, where a resource block refers to a smallest unit of resources, in terms of a number of subcarriers and time slots that can be assigned;
  • pRB: number of resource blocks used on the uplink to a wireless access network node; and
  • DC: duty cycle that represents how often the resource blocks are available over a specified time period.

The foregoing parameters can be expressed in a vector notation form, P_c, as follows:

$\begin{array}{cc}{P}_c=\left(\begin{array}{c}\mathrm{FREQ}\\ \mathrm{FBW}\\ \mathrm{nRB}\\ \mathrm{pRB}\\ \mathrm{TxPwr}\\ \mathrm{DC}\end{array}\right).& \left(\mathrm{Eq}.3\right)\end{array}$

In accordance with some implementations, the model 118 takes as input values of the parameters of P_c, and outputs values of the handover control parameters of P_r.

The following describes further details according to some implementations for determining the model 118. The model 118 is represented as Win Eq. 10 further below. Although a specific technique is described for determining the model 118, it is noted that in other examples, other techniques for determining the model 118 can be used.

If a set of handover control parameters P_r′ is used for dynamic handover decisions between APs (such as APs 102 and 104 in FIG. 1), then a metric, M, for measuring the performance of using this set of parameters, P_r′, is expressed by:

$\begin{array}{cc}M\left(P_r^{\prime }\right)=\frac{1}{N_r}\sum _r^{}\mathrm{TP}\left(P_r^{\prime }\right).& \left(\mathrm{Eq}.4\right)\end{array}$

where M is an average of measurements of throughput that can be achieved based on performing handovers using the handover control parameters of by P_r′. Throughput can refer to a rate of communication that can be achieved over a wireless communication medium.

In some examples, a technique for determining a function is based on computing:

$\begin{array}{cc}=\underset{f}{\arg }\max (M\left(f\left(P_c\right)\right),& \left(\mathrm{Eq}.5\right)\end{array}$

i.e., the technique looks for a function so that using this function to determine the handover control parameters leads to an optimal solution in terms of average throughput (expressed by M). Since M is a convex function reaching its maximum around P_r, then Eq, 5 simplifies to:

$\begin{array}{cc}=\underset{f}{\arg \max }\left(M\left(f\left(P_c\right)\right)\right)\iff =\underset{f}{\arg \min }\left(P_r-f\left(P_c\right)\right).& \left(\mathrm{Eq}.6\right)\end{array}$

Written differently:

$\begin{array}{cc}\begin{array}{c}{P}_r\approx \left(P_c\right)\\ =\left(P_c\right)+ϵ\\ ={\hat{P}}_r+ϵ,ϵ1,\end{array}& \left(\mathrm{Eq}.7\right)\end{array}$

where P_r are the exact parameters determined experimentally, {circumflex over (P)}_r are the estimated values using Eq. 7, and ε is the modeling error.

In some examples, the technique can restrict the function to be linear, i.e., if x=[1, x₁, . . . , x_n]^T is a vector and f is a linear function then:

$\begin{array}{cc}f\left(x\right)=\sum _{i=0}^nw_i\times x_i=w\times x,& \left(\mathrm{Eq}.8\right)\end{array}$

where:

w=[w ₀ , . . . , w _n].  (Eq. 9)

Using the same notation as above, one can write:

{circumflex over (P)} _r =W×P _c.  (Eq. 10)

In other examples, f can be a non-linear function

In Eq. 10, W represents the model 118, such that once W is derived, values of the parameters in P_c can be used to predict the handover control parameters of P_r (note that P_r represents values of the handover control parameters that are less optimal than values of the handover control parameters of P_r that are considered to be optimal).

The ∥∥₂ norm can be used for deriving the expression of the function W, i.e., the technique is looking for the function W that minimizes the sum of the squared errors,

$\begin{array}{cc}\begin{array}{c}\xi \left(W\right)={P_r-W\times P_c}_2\\ =E\left({\left(P_r-W\times P_c\right)}^2\right),\end{array}& \left(\mathrm{Eq}.11\right)\end{array}$

where the E operator denotes expectancy.

Eq. 11 can be written as:

$\begin{array}{cc}\begin{array}{c}\xi \left(W\right)=E\left(P_r\times P_r^t+W\times P_c\times P_c^t\times W^t-2P_r\times W\times P_c\right)\\ =E\left(P_r\times P_r^t\right)+E\left(W\times P_c\times P_c^t\times W^t\right)-2E\left(P_r\times P_c^t\times W^t\right).\end{array}& \left(\mathrm{Eq}.12\right)\end{array}$

Minimizing the error defined in Eq. 12, implies that ∂ξ(W)/∂W=0.

$\begin{array}{cc}\frac{\partial \xi \left(W\right)}{\partial W}=2W\times E\left(P_c\times P_c^t\right)-2E\left(P_r\times P_c^t\right)=0& \left(\mathrm{Eq}.13\right)\\ W\stackrel{\iff }{=}E\left(P_r\times P_c^t\right)\times {E\left(P_c\times P_c^t\right)}^{-1}.& \left(\mathrm{Eq}.14\right)\end{array}$

W is the cross-correlation matrix between P_r and P_c divided by the correlation matrix of P_c. In this case, {circumflex over (P)}_r is defined as:

{circumflex over (P)} _r =E(P_r×P_c^t)×E(P_c×P_c^t)⁻¹×P_c.  (Eq. 15)

Thus, in some implementations, finding the values of W is tightly related to estimating E(P_r×P_c^t) and E(P_c×P_c^t).

Experimental measurements can be made in such a way that a set of data expressed as a pair of values can be derived as follows:

(P_r,P_c)_i=(P_rⁱ+ε_r,P_rⁱ+ε_c),  (Eq. 16)

where ε_r and ε_c are P_r measurement errors and P_c measurement errors, respectively. The experimental measurements are measurements of RSSI made with different settings of the handover control parameters of P_r and parameters of P_c. For simplification reasons, it can be assumed that ε_r and ε_c are independent, i.e., E(ε_r, ε_c)=0. In this case:

$\begin{array}{cc}\begin{array}{c}{E\left(P_r\times P_c^t\right)}_{\mathrm{ij}}=E\left(\sum _{k=1}^N\left[P_{\mathrm{rk}}^i+{ϵ}_r\right]\times \left[P_{c,j}^k+{ϵ}_c\right]\right)\\ =E\left(\sum _{k=1}^NP_{\mathrm{rk}}^i\times P_{c,i}^k\right),\end{array}& \left(\mathrm{Eq}.17\right)\\ \begin{array}{c}{E\left(P_c\times P_c^t\right)}_{\mathrm{ij}}=E\left(\sum _{k=1}^N\left[P_{\mathrm{rk}}^i+{ϵ}_c\right]\times \left[P_{c,j}^k+{ϵ}_c\right]\right)\\ =E\left(\sum _{k=1}^NP_{\mathrm{ck}}^i\times P_{\mathrm{cj}}^k\right)+{\partial }_{\mathrm{ij}}\times E\left({ϵ}_c^2\right),\end{array}& \left(\mathrm{Eq}.18\right)\end{array}$

where ∂_ij=1 if i=j and 0 elsewhere. The error of the measurements of P_c are only present on the diagonal of the matrix E (P_c×P_c^t). N in the above equations is the number of measurements.

Once Eqs. 17 and 18 are used to derive E(P_r×P_c^t) and E(P_c×P_c^t), then the model 118, represented by the function W, can be derived according to Eq. 14 above.
