Paging reading conflict management in dual standby handsets

摘要

A wireless communication apparatus, which is configured to receive and transmit data via cells of at least two network cell belonging different networks, selects one of the networks to listen to in case of conflict. The apparatus has a radio transceiver module and a processor. The processor includes a driver of the radio transceiver module to choose one network that the radio transceiver module should listen to, a pattern detector configured to obtain a paging block repetition pattern for each of the networks, and a conflict manager configured to select the network to listen to when paging blocks from different networks collide. The conflict manager selects the network based on the paging block repetition patterns to minimize the probability of loss of a paging message associated to the paging blocks by predicting the next paging block transmissions.

1. A wireless communication apparatus configured to receive and transmit data via a first cell belonging to a first wireless network and a second cell belonging to a second wireless network, the apparatus comprising:
a radio transceiver module; a first interface for a first subscriber identity card camping on the first cell; a second interface for a second subscriber identity card camping on the second cell; a processor coupled to the radio transceiver module, the first and the second interfaces and including a driver of the radio transceiver module configured to choose the first or the second wireless network to which the radio transceiver module should listen to; a pattern detector configured to obtain, for each of the first and second wireless networks, a paging block repetition pattern for paging blocks assigned to the apparatus; and a conflict manager configured to select the first or the second wireless network to listen to when a paging block of the first wireless network collides with a paging block of the second wireless network, wherein the conflict manager is configured to select the first or the second wireless network based on the paging block repetition patterns to minimize a probability of loss of a paging message associated to the paging blocks by predicting next paging block transmissions, wherein each of the first and second wireless networks is configured to signal a call for the apparatus by applying a pattern assigned to the apparatus on at least two paging blocks, delays between two consecutive paging blocks on which the pattern is applied being predetermined and specific to each of the first and second wireless network and forming a repetition pattern, and wherein the pattern detector is configured to detect, for each of the first and the second network, the predetermined delays, and wherein the apparatus is configured to
request a dummy service inducing an answer and, upon reception of the paging blocks, to determine and save the predetermined delays without answering to the first or second wireless network, orverify the paging block repetition pattern by postponing answering to a network call to the apparatus until a last paging block assigned to the apparatus is received.
