A method for managing radio communications between a gateway and a plurality of sensors of a system for tracking assets is disclosed. The method includes: obtaining properties of a currently tracked asset; determining a current connection configuration for radio connections between the gateway and the plurality of sensors; identifying a preferred connection configuration for radio connections between the gateway and the plurality of sensors based on the properties of the currently tracked asset, the preferred connection configuration having at least one physical layer characteristic that is different from the current connection configuration; and in response to the identifying, causing the gateway and at least one of the plurality of sensors to switch from the current connection configuration to the preferred connection configuration for establishing a new radio connection.

A method and apparatus for a back-off timer having different retry time classes, the method checking whether a connection establishment attempt for a first service on a connection slot is in a back-off time that equals or exceeds a predetermined threshold; and if yes, allowing a second service access to the connection slot.

Systems and methods are disclosed for automatically powering on and off one or more radios in a mobile device according to a schedule generated automatically for each of the one or more radios. To generate the schedules, each of the one or more radios are powered on for a designated period of time. During the designated period of time, information is recorded specifying the availability of network coverage for each of the radios. A schedule for each of the radios is then generated according to this information. Each radio is subsequently automatically powered on and off according its schedule.

A method and apparatus for customizing foreground application inactivity timer values based on network maximum tunnel count conditions, the method determining a maximum tunnel count value at a mobile device; and configuring at least one tunnel inactivity timer value based on the maximum tunnel count value.

Method and apparatus for customizing a focus inactivity timer based on network watermark conditions

A method and apparatus for prevention of user-level applications from initiating data connection establishment using signaling from radio code, the method including receiving a request from an application on a mobile device at a tunnel management module on the mobile device, the request being to establish a data connection with a network; checking a state of a tunnel for the data connection at the tunnel management module; blocking the connection request if the tunnel for the data connection is in a stalled state; and allowing the connection request to proceed to a networking access interface module if the tunnel for the data connection is not in a stalled state.

A method for monitoring use of a mobile hotspot function in a wireless device, comprising: storing a last access time for a client within a memory of the wireless device, the last access time being a time when the hotspot function last performed a network address translation for the client; determining whether a difference between a current time and the last access time exceeds a threshold; and, if the difference exceeds the threshold, generating an indication that the mobile hotspot function is not in use by the client.

A method and apparatus for resetting a maximum tunnel watermark, the method starting a reset timer for a maximum tunnel count at a mobile device; on expiration of the reset timer, checking whether a current value for the maximum tunnel count is less than a maximum value for the maximum tunnel count, and if yes, setting the current value of the maximum tunnel count to the maximum value of the maximum tunnel count.
