Managing Connections to a Network in a Mobile Device
Description
The present invention rebtes to managing connections to a network in a mobile device. More particularh:, the present invention relates to managing connections by defining an initial connection state for a connection, and determining whether to change the connection state when a predefined event occurs.
Mobile devices, such as mobile telephones and portable computers with networking capabilities, have gained popularity in recent years. Mobile devices allow a user to connect to a network to send and receive data to and from the network. As devices increase in compkxity, it is becoming common to have many applications running on a device at any given time. Each application may open several connections over a communications link to the network, for example to communicate with other mobile devices and servers.
In a conventional mobile device, it is common that traffic generated by the device does not utilise the network or local resources efficiently. For example, an application may not be configured to make the best use of the available bandwidth when connected to the network. Other problems include applications repeatedly trying to connect to incorrectly configured access points, continuoush trying to set up arid tear down contexts, and leaving unused connections open. Such problems can occur when the mobile device is initially configured by a network provider and subsequently modified by a user, when applications leave ports open after they are no onger needed, and when a connection path is maintained to a server that is no longer available.
According to the present invention, there is provided a method for use in a mobile device configured to open a plurality of connections for sending and/or receiving io data over a communications link to a network, the method comprising obtaining, for each connection, a plurality of parameters relating to characteristics of the connection, defining a connection state for each connection based on the plurality of paratueters for the connection, the connection state being used by the mobile device to determine how the connection may use the communications link, detecting a predefined event, and determining, for each connection, whether to change the connection state of the connection in response to the predefined event, according to a plurality of predefined rules. )
The plurality of parameters may include at least one ot a connection type parameter related to a pattern of usage of the connection, a frequency-of-use parameter related to how frequently the connection is used, and a bandwidth parameter related to an amount of bandwidth used by the connection.

The information about the pattern of usage may comprise information about whether data transfer over the connection is hursty, continuous, or periodic.
The predefined rules may include information about whether to change a connection state of one of the connections in response to a combination of two or more different predeflned events being detected in a predetermined time period.
The plurality of predefined events may include at least one of a change in stored energy level of a battery of the mobile device, a change in signal strength of the communications link, a message received from the network, a change in the number of available net\vorks to which communications links can he established, a change in the number of connections currently open, and a change in the number of failed connections, a failed connection occurring when one of the connections attempts to communicate with a remote device that is no longer available.
If a change in stored energy level of a battery of the mobile device is detected, the method may further comprise displaying a user interface for a user to select one or more of the connections, and terminating or suspending each selected connection.
If a change in signal strength of the communications link is detected, the method may further comprise obtaining information about a bandwidth requirement of each connection, and applying traffic shaping when transferring data through ones of the connections having handwidth requirements above a threshold level.
If it is determined to change the connection state of one of the connections, the method may further comprise requesting user approval of the change of connection state, wherein if user approval is received the connection state is changed, and if user approval is not received the connection state is not changed.

The plurahty of predefined connection states may include at least one of a high priority state, a low jri ority state, a suspended state, and a terminated state.
Detecting the predefined event may comprise directly detecting the predefined event, or receivilig information that the predefined event has occurred.
Detecting a predehned event may comprise detecting one of a purahty of predefined events.
According to the present invention, there is a'so provided a computer-readable storage medium storing a computer program which, when executed on a processor, causes the processor to perform the method.
According to the present invention, there is further provided a mobile device configured to open a pura]itv of connections for sending and/or receiving data over a communications link to a network, the mobile device comprising an event detection module for detecting a predefined event, and a net\vork traffic management module configured to obtain, for each connection, a plurality of parameters relating to characteristics of the connection, define a connection state for each connection based on the plurality of parameters for the connection, the connection state being used by the mobile device to determine how the connection may use the communications link, and determine, for each connection, whether to change the connection state in response to the predefined event being detected, according to a plurality of predefined rules.
The event detection module may he configured to obtain information about data transfer characteristics of each connection, and the predefined event may comprise a change in the data transfer characteristics of one of the connections during a predetermined time period.
The event detection module may he configured to detect at least one of a change in stored energy level of a battery of the mobile device, a change in signal strength of the communications link, a message received from the network, a change in the number of available networks to which communications links can be established, a change iti the number of connections currently open, and a change in the number of failed connections, a failed connection occurring when one of the connections attempts to communicate with a remote device that is no longer available.
Embodiments of the inesent invention wil now he described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 illustrates a mobile device for communicating with a network, according to an embodiment of the present invention; Figure 2 illustrates a method of managing connections in a mobile device, according to an embodiment of the present invention; Figure 3 illustrates predetermined connection states, according to an embodiment of the present invention; and Figure 4 illustrates a matrix for determining whether to change a cotinection state, according to an embodiment of the present invention.
Referring now to Fig. 1, a mobile device for communicating with a network is illustrated, according to an embodiment of the present invention. The mobile device 100 can execute a plurality of applications 102, each of which can open a plurality of connections 104 to the network 110 via a communications link 120.
The communications link 120 may he a wired or wireless connection.
The plurality of connections 104 may have different characteristics, depending on the nature of data being transferred by the connection 104. Some connections may frecuently send requests to the network, whereas others may only exchange data intermittently. A pattern of usage can he defined for each connection. For example, a connection used by an instant messaging client may be referred to as "bursty", since messages and files are exchanged in irregular bursts. Similarly, a connection used by an internet browser may also be bursty, as data may only be transferred when navigating to a new page. In contrast, applications such as streaming video and voice over internet protocol (VOIP) will typically require connections that transfer data in a constant stream. Such connections are referred to as "continuous". Furthermore, other applications may utilise connections that send data at regular intervals, for example a weather update application. Such connections are referred to as "periodic".
In addition to a pattern of usage, a connection can also be characterised by its bandwidth requirements. Referring to the above-mentioned examples, the instant messaging client, internet browser and weather application will typically requite relatively low bandwidth connections, as only a relatively small amount of data is transferred at any time. In contrast, applications such as streaming video and VOIP will have a relatively high bandwidth requirement.
Coiitections can also be characterised by how frequently data is transmitted. This property is distinct from that of the pattern-of-uge, such as hursty, periodic or continuous. In more detail, a periodic connection may request data with a high frequency, for example an internet browser may open a periodic connection for a web page that is configured to automatically refresh every 30 seconds. In contrast, a weather update application may also use a periodic connection, but may only require updates once every hour. This connection can he characterised as relatively low frequency.
i\ further parameter that can be used to characterise a connection is the importance of the connection. For example, the weather update application xvould normally have a low importance as the information provided by the application is not critical to a user's requirements. In contrast, other applications may have a high importance, and should he prioritised. For example, a connection used by an eHealth application may he characterised as a high importance connection, since there may be a health risk to a user if the application ceases to function correctly.
In embodiments of the present invention, a plurality of parameters can he defined for each con ieetion, to describe the nature of the connection. The parameters relate to characteristics of the connection, and can be provided by an application when sett[ng up the connection, or cou'd for example he received from the network provider or from a user of the mobile device. The parameters may include information about the pattern of usage. In the present embodiment, the pattern of usage is defined by selecting one of a plurality of predetermined categories, namely bursty, continuous or periodic. In other embodiments, other categories [nay be defined. Additionally, the parameters may include information about the bandwidth requirements of a connection, for example high, medium or low. The parameters may also included information about the frequency with which the connection is used, for example high, medium or low. Further still, the parameters may include priority information relating to the importance of the connection, for defining whether the connection should he treated with a high or low priority when allocating resources (e.g. handwidth, memory) to a plurality of connections.
Resources may preferentially he allocated to higher priority connections than to lower priority connections. Additionally, if it is required to suspend or terminate connections to free up resources, lower priority connections may he terminated or suspended before higher priority connections. In the present embodiment, the priority information for a given connection may he defined as high, medium or low, according to an importance of the connection. In some embodiments, when opening the connection the nu)hile device may request a user to select the importance of the connection from a list of predetermined options, such as high, medium or low.
In the present embodiment, the mobile device includes a network traffic management module that is arranged to prioritise data flows from different connections currently open on the mobile device, hased on the parameters related to characteristics of each connection. Data flows from the connections can also he prioritised in response to certain predefined events occurring. For example, when network or local resources are scarce then lower priority connections may be suspended or terminated. When there is an increase in the available resources, connections that have been reduced in priority or suspended can he promoted or resumed. By detecting predefined events, such as changes in availability of a particular resource, embodiments of the present invention can constantly adapt to changes in network and client resources by reevaluating the importance of each data flow and reprioritiaing connections accordingly. A method of managing connections on a mobile device will no\v he described with reference to Fig. 2.
Firstly, in step S20i, the mobile device obtains the parameters for each connection currently open on the device. As described above, the parameters may define the nature and importance of each connection, for example based on location, cost, frejueney, patterns of usage, and data size. The parameters may be fixed, and defined by a manufacturer or network provider, or may be dynamic and can he updated during use. )
Next, in step S202, the network traffic management module sets an initial connection state for each connection. Here, the method is executed for existing connections that are already open. In other embodiments, the initial connection state may be defined when the connection is first opened. In the present embodiment, the connection states are defined as a ranking table, in which the connections are ordered according to the characteristics of each connection as defined by the parameters. An example of a ranking table is shown below, using the connections shown in Fig. 1:
CONNECTION RANKING
CONN 4 1 CONN2 2 CONN5 3 CONN 1 4-CONN 3 5 (:ONN 6 6 Although in the present embodiment a ranking table is used, in other embodiments the connection states may he defined using a different approach. For example, a plurality of predefined connection states may be defined, and the connection state for a particular connection may he set by selecting one of the predefined connection states. In such embodiments, different connections may both be assigned the same predeflned connection state.
Once the connection states have been defined, in step S203 the network traffic management module continually or periodically checks whether any of a plurality of predefined events have occurred. As an example, a predefined event may comprise a power level of a battery of the mobile device falling below a certain level, or may comprise a decrease or increase in signal strength of the communications link.
Various actions may he taken in response to a predeflned event. For instance, if the signal strength decreases below a threshold level, traffic shaping may he employed to make more efficient use of available bandwidth. Traffic shaping may he used on all connections in response to the predetermined event, or may only be used on connections having a high bandwidth requirement, e.g.a hand\vidth requirement above a predetermined threshold.
For any given resource, a plurality of events may be defined. For example, with reference to changes in battery level, ditferent predefined events cou'd correspond to charge levels of 25, 50, 75 and 100 Other events can be defined as appropriate, and may include cost, network resources, and so on.
An event may be directly detected, or may he detected by receiving information that the event has occurred. For example, information may he received from the network provider that a particular server is no longer available. Additionally, in some embodiments data transfer characteristics of each connection may he monitored and recorded, and one predefined event may correspond to a change in observed data transfer characteristics of a connection. The data transfer characteristics may include information about some of the same properties defined by the input parameters, for example the pattern-of-usage of the connection, frequency with which the connection is used, average amount of data transferred, etc. If one of the predefined events is detected, then in step S204 it is determined, for each connection, whether to change the connection state in response to the predetermined event. In the present example, in which a ranking table is used to define the connection states, it is determined whether to reorder the ranking of the connections in response to the event. To determine whether or not to change the connection state, the network traffic management module refers to predetermined rules. For example, when the event is a change in observed data transfer characteristics, the predetermined rules may indicate that previously suspended connections may he reopened, while others may he suspended or closed, depending on how each connection is making use of the available bandwidth and the resources that are currently available. The ranking can therefore be adapted according to the amount, type and frequency of usage, or usage reports that are received from the net\vork provider. )
As a further example of a predefined rule, if it is detected that available resources such as available bandwidth or batter power have fallen below a predetermined threshold, it may be determined that lower priority connections are to be suspended and a bandwidth allocated to higher priority connection reduced, until more resources become available once again.
Additional examples of predefined rules are shown in the table below:
RULE ACTION
Low battery indication Prompt user to close down low priority appl i cat on s Low signal indication Traffic shape lP flows for better bandwidth utilization Low battery and low signal indication Close down all but critical applications Event 3 & event 5 have 1)0th occurred (Jose down all applications As shown in the above example, the predefined rules may also include information about whether connection states should he changed in response to a particular combination of events occurring.
In step S204, it may be determined that it is not necessary to update the connection state of any connections. In this case, the network traffic management module returns to step S203 and waits until the next predefined event is detected.
Alternatively, if it is determined that a connection state is to he changed, the network traffic management module proceeds to step S205 and updates the connection state. Any number of connection states may be updated in response to any given predetined event. -Il-
After the connection state has been updated, in step S206 it is determined whether the new connection state is a terminated state, i.e. the connection is no longer required and is closed. Tf all connections are terminated, i.e. there are no currently active or suspended connections, the network traffic management module can cease detecting the predefined events, at least until new connections are opened. If in step S206 it is determined that not all connections are terminated, the network traffic management module returns to step S203 and continues to monitor for predefined events.
Referring now to Fig. 3, a plurality of predefined connection states are illustrated, according to an embodiment of the present invention. In this embodiment, instead of defining connection states by ranking connections in a table, the connection state of each connection can he set he selecting one of the plurality of predefined connection states. Tn the Present embodiment, the possible connection states include a normal priority state, low priority state, high priority state, suspended state and terminated state. In the suspended state, the connection is temporarily closed hut can later be reopened. In the terminated state, the connection is permanently closed. As shown in Fig. 3, when a new connection is created it is initially assigned a normal priority connection state. The connection state may however he modified according to the input parameters, or in response to a predefined event. Once the initial state is set, if no predefined events are detected the connection will retain the initial connection state until it is closed.
An alternative implementation to the ranking table is shown in Fig. 4. In this embodiment, a matrix is stored for relating each connection to the predefined events. In particular, the matrix enables the network traffic management module to quickly and efficiently identify whether the connection state of a particular connection is to be changed in response to a particular event. In Fig. 4, an open circle at an intersection indicates that the connection state of the corresponding connection should he changed when the corresponding event occurs. The matrix provides an indicator of which connections are likely to be affected by which events.
In Fig. 4, the event matrix only indicates the type of exent and not necessary the level or threshold of the event, or what particular action should be taken. Once it is determined from the matrix that the connection state of a particular connection is to be changed, the network traffic management module may refer to other predefined rules such as those described above with reference to step S204 of Fig. 2, to determine how the connection state is to he changed, e.g. whether to increase or decrease the priority of the connection, or suspend or terminate the connection.
In some embodiments of the present invention, user input may be incorporated when determining whether to change the connection state of a connection. For example, if a connection is to be terminated, the user may be informed through a user interface of the mobile device of the decision to terminate the connection. The user intcrface may only notify the user that the connection state has been changed, or may explicitly request the user's permission before changing the connection state.
If the connection state of a particular connection changes rapidly, i.e. \vithin a predetermined time period, it may he determined not to notify the user. This can ensure that rapid changes do not become a source of distraction or irritation to the user.
By continuously monitoring factors such as available resources and data transfer behaviour of each connection, embodiments of the present invention can efficiently prioritise traffic flows for a plurality of connections. Embodiments of the present invention can therefore improve the performance and efficiency of the mobile device, and reduce the battery consumption and data bandwidth consumption.
\Vhil st certain embodiments of the invention have been described above, it will he clear to the skilled person that nmny variations and modifications are possible without departing from the scope of the invention as defined in the accompanying c 1 aim s. -[3-
