  • the present technology relates to communication devices and nodes in wireless communications networks and computer program, computer program products and carriers, and to methods in said communication devices and nodes.
  • the present technology relates to saving battery capacity in and waking up communication devices.
  • the always-on cellular connectivity can consume too much battery which is not acceptable.
  • cellular connectivity Once cellular connectivity is turned off, it is a problem to turn on the cellular connectivity later because it can be very difficult to reach the m2m device. Unlike consumer devices, the end user can control the consumer device directly to turn off/on cellular connectivity anytime. Therefore, a remote server cannot communicate to the m2m device any more via the cellular connectivity once the cellular connectivity is off. Even for consumer device the end user most likely doesn't know when to turn on the consumer device cellular connectivity as needed, e.g. once cellular connectivity is off end users don't know when there will be a critical phone call or sms or server pushed data upcoming.
  • One solution of device initiated cellular connectivity wakeup is to provide the communication device with sensors for registering trigger events.
  • Device sensor detects an event and turns on the cellular connectivity according to the sensor/event triggering function configured in the device, i.e. when there is fire alarm triggered and the fire alarm needs to communicate to the remote server, so it triggers the device to turn on cellular connectivity. Further one example is when a device detects the device initiated traffic request, i.e. real traffic request, not heartbeat traffic, the device shall switch on the cellular connectivity.
  • the device initiated traffic request i.e. real traffic request, not heartbeat traffic
  • Another way of initiated cellular connectivity wakeup is to set a timer when turning off the cellular connectivity, when the timer expires, the cellular connectivity shall be turned on automatically. But the timer introduces other problems such as the delay for the upcoming communication due to the non- real-time wake up of cellular connectivity depending on the timer. If the timer is long it will be unacceptable delay for real-time communication need; if the timer is short it will not save device battery and still waste network signaling, due to the unnecessary and frequent wake up (turn off/on activities) when there is no communication need.

Abstract

La présente invention concerne des procédés, des nœuds dans un système de communication, et des dispositifs de communication, pour économiser la capacité d'une batterie sans perdre la connectivité avec le système de communication. Lorsque la connectivité cellulaire d'un dispositif de communication sans fil est désactivée, une autre connectivité non cellulaire est activée sur le dispositif. La connectivité non cellulaire est utilisée pour activer la connectivité cellulaire ultérieurement, par exemple lorsqu'un serveur distant doit communiquer avec le dispositif.
