Abstract

Methods and apparatus enabling a wireless network to dynamically change or implement paging mode operation, such as optimization based on one or more network parameters. In one embodiment, the wireless network is a cellular network (e.g., 3G UMTS or LTE), and both base stations and cellular user devices dynamically configure the paging mode operation based on various desired operational attributes relating to the network parameters. Such flexible paging mechanisms may be published to the network users via several methods, and users with appropriately enabled user devices may improve their power and applications performance. Base stations may also advantageously reclaim freed-up cellular resources to support other services. Legacy subscribers are also not affected.

35. A user equipment (UE), comprising:

a transceiver configured to establish a first connected state with a cellular network, wherein a further UE and the cellular network are in a second connected state; and

a baseband processor connected to the transceiver configured to;

receive timing data, wherein the timing data indicates a plurality of paging transmissions to be transmitted on at least a first carrier of a plurality of aggregated carriers corresponding to the cellular network; and

monitor only the first carrier of the plurality of aggregated carriers for a first paging transmission of the plurality of paging transmissions based on the timing data, wherein the further UE is configured to monitor only a second carrier of the plurality of aggregated carriers for a second paging transmission.

36. The UE of claim 35, wherein the first connected state and the second connected state is a RRC_connected state.

37. The UE of claim 36, wherein the cellular network transmits the timing data to the UE according to a first mode of paging transmission operations based on the UE and the cellular network being in the RRC_connected state.

38. The UE of claim 35, wherein the UE receives the timing data based on the UE monitoring a Physical Downlink Control Channel (PDCCH) during at least one predetermined time interval.

39. The UE of claim 35, wherein the plurality of paging transmission is transmitted to the UE on a Physical Downlink Shared Channel (PDSCH).

40. The UE of claim 35, wherein the plurality of paging transmissions each correspond to one of a network service or a network notification specifically addressed to the UE.

41. A baseband processor, configured to perform operations comprising:

receiving timing data, wherein the timing data indicates a plurality of paging transmissions to be transmitted on at least a first carrier of a plurality of aggregated carriers corresponding to the cellular network; and

monitoring only the first carrier of the plurality of aggregated carriers for a first paging transmission of the plurality of paging transmissions based on the timing data, wherein a further baseband processor is configured to monitor only a second carrier of the plurality of aggregated carriers for a second paging transmission.

42. The baseband processor of claim 41, the operations further comprising:
