Method to reduce power consumption in dual receive MUSIM devices
A method includes aligning a plurality of paging occasions across at least two identities of a communication device; and requesting and receiving from a communication network a paging occasion for the communication device with at least two identities using at least one of the identities to perform the aligning; or requesting and receiving from the communication network a reallocation of a paging offset using at least one of the identities to perform the aligning.
1 . An apparatus comprising:
at least one processor; and
at least one non-transitory memory including computer program code;
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
align a plurality of paging occasions across at least two subscription identities of a Multi Universal Subscriber Identity Module (multi-USIM) device by coordinating a timing of the plurality of the paging occasions according to a specified temporal relationship; and
requesting and receiving from a communication network a paging occasion for the multi-USIM device with at least one of the subscription identities to perform the aligning; or
requesting and receiving, from the communication network, a reallocation of a paging offset for the at least one of the subscription identities to perform the aligning.
2 . The apparatus of claim 1 , wherein the multi-USIM device comprises at least two receivers.
3 . The apparatus of claim 1 , wherein the aligning is a full alignment such that paging monitoring of at least two of the subscription identities is simultaneous, and at least two receiver chains are active.
4 . The apparatus of claim 1 , wherein the aligning is a sequential alignment such that paging monitoring of at least two of the subscription identities is sequential in time.
5 . The apparatus of claim 1 , wherein the aligning is a partial alignment such that paging monitoring of at least two of the subscription identities partially overlap.
6 . The apparatus of claim 1 , wherein the aligning creates intended gaps between the plurality of paging occasions.
7 . The apparatus of claim 1 , further causing the apparatus to provide assistance information from at least one identity of the multi-USIM device to the communication network to indicate a preferred location for the paging occasion.
8 . The apparatus of claim 7 , wherein the preferred location comprises at least one of:
a start slot and an end slot;
a start frame and an end frame; or
a start time and an end time.
9 . The apparatus of claim 1 , further causing the apparatus to provide a field in a signaling exchange for registration of at least one identity of the multi-USIM device to the communication network for the reallocation of the paging offset.
10 . The apparatus of claim 1 , further causing the apparatus to in response to receiving an indication of unavailability of the paging occasion from the communication network, request and receive the paging occasion using a different one of the at least two identities.
11 . The apparatus of claim 1 , further causing the apparatus to prioritize a full alignment over a sequential or partial alignment of the paging occasions by the multi-USIM device.
12 . The apparatus of claim 1 , wherein the at least two subscription identities are at least one of a subscriber identity module, a universal subscriber identity module, an embedded subscriber identity module, or a certificate.
13 . A method comprising:
aligning a plurality of paging occasions across at least two subscription identities of a Multi Universal Subscriber Identity Module (multi-USIM) device by coordinating a timing of the plurality of the paging occasions according to a specified temporal relationship; and
requesting and receiving from a communication network a paging occasion for the multi-USIM device with at least one of the subscription identities to perform the aligning; or
requesting and receiving from the communication network a reallocation of a paging offset for the at least one of the subscription identities to perform the aligning.
14 . The method of claim 13 , wherein the multi-USIM device comprises at least two receivers.
15 . The method of claim 13 , wherein the aligning is a full alignment such that paging monitoring of at least two of the subscription identities is simultaneous, and at least two receiver chains are active.
16 . The method of claim 13 ,
wherein the aligning is a sequential alignment such that paging monitoring of at least two of the subscription identities is sequential in time; or
wherein the aligning is a partial alignment such that paging monitoring of at least two of the subscription identities partially overlap.
17 . The method of claim 13 , wherein the aligning creates intended gaps between the plurality of paging occasions.
18 . The method of claim 13 , further comprising providing assistance information from at least one identity of the multi-USIM device to the communication network to indicate a preferred location for the paging occasion.
19 . The method of claim 18 , wherein the preferred location comprises at least one of:
a start slot and an end slot;
a start frame and an end frame; or
a start time and an end time.
20 . An apparatus comprising:
at least one processor; and
at least one non-transitory memory including computer program code;
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
configure at least one of a paging information element associated with a paging occasion, or a reallocation of a paging offset, so as to align a plurality of paging occasions across at least two subscription identities of a multi-Universal Subscriber Identity Module (multi-USIM) device according to a specified temporal relationship; and
provide the configured paging information element or the reallocated paging offset to the multi-USIM device.
