Abstract

A network access device is provided with one or more processors configured for macrotechnology-based transmission to a multi-mode user equipment of a signal including a plurality of data portions and a plurality of gaps between one or more of the plurality of data portions, wherein at least one of the gaps is used by the multi-mode user equipment for measurement of a first signal strength of a microtechnology-based network.

Claims

1. A network access device, comprising:

one or more processors configured for macrotechnology-based transmission to a multi-mode user equipment of a signal including a plurality of data portions and a plurality of gaps between one or more of the plurality of data portions, wherein at least one of the gaps is used by the multi-mode user equipment for measurement of a first signal strength of a microtechnology-based network, wherein the processor is further configured to use a gap previously designated for macrotechnology-based signal strength measurement to perform the microtechnology-based signal strength measurement.

2. The network access device of claim 1, wherein the at least one of the plurality of gaps is generated based upon a request received from the multi-mode user equipment.

3. The network access device of claim 1, wherein the processor is configured to:

define a new common measurement gap pattern usable by both a microtechnology and a macrotechnology.

4. The network access device of claim 1, wherein the microtechnology is one of:

a Wireless Fidelity network,

a wireless local access network using a home base station,

a wireless local access network using a home Enhanced Node B, and

a Wireless Local Area Network; and

wherein the macrotechnology is one of;

a Long Term Evolution (LTE) network,

a Ultra Mobile Broadband (UMB) network;

a Code Division Multiple Access 2000 network;

a Universal Mobile Telecommunications System Terrestrial Radio Access Network;

a Global System for Mobile Communications (GSM) network;

a GSM EDGE Radio Access Network; and

a 1×

Evolution-Data Optimized network.

5. A method for measuring signal strength, comprising:

transmitting a macrotechnology-based transmission to a multi-mode user equipment of a signal including a plurality of data portions and a plurality of gaps between one or more of the plurality of data portions;

using at least one of the gaps at the multi-mode user equipment for measurement of a first signal strength of a microtechnology-based network; and

using a gap previously designated for macrotechnology-based signal strength measurement to perform the microtechnology-based signal strength measurement.

6. The method of claim 5, wherein the at least one of the plurality of gaps is generated based upon a request received from the multi-mode user equipment.

7. The method of claim 5, further comprising:

defining a new common measurement gap pattern usable by both a microtechnology and a macrotechnology.

8. The method of claim 5, wherein the microtechnology is one of:

a Wireless Fidelity network,

a wireless local access network using a home base station,

a wireless local access network using a home Enhanced Node B, and

a Wireless Local Area Network; and

and wherein the macrotechnology is one of;

a Long Term Evolution (LTE) network,

a Ultra Mobile Broadband (UMB) network;

a Code Division Multiple Access 2000 network;

a Universal Mobile Telecommunications System Terrestrial Radio Access Network;

a Global System for Mobile Communications (GSM) network;

a GSM EDGE Radio Access Network; and

a 1×

Evolution-Data Optimized network.

9. A multi-mode user equipment comprising:

one or more components configured to;

receive a macrotechnology-based signal comprising a plurality of data portions and a plurality of gaps between one or more of the plurality of data portions;

during at least one of the gaps, measure a first signal strength of a microtechnology-based network, wherein the at least one of the gaps used to perform the microtechnology-based signal strength measurement was previously designated for macrotechnology-based signal strength measurement.

10. The multi-mode user equipment of claim 9, wherein the at least one of the plurality of gaps is generated based upon a request from the multi-mode user equipment.

11. The multi-mode user equipment of claim 9, wherein the one or more components are further configured to:

define a new common measurement gap pattern usable by both a microtechnology and a macrotechnology.

12. The multi-mode user equipment of claim 9, wherein the microtechnology is one of:

a Wireless Fidelity network,

a wireless local access network using a home base station,

a wireless local access network using a home Enhanced Node B, and

a Wireless Local Area Network; and

wherein the macrotechnology is one of;

a Long Term Evolution (LTE) network,

a Ultra Mobile Broadband (UMB) network;

a Code Division Multiple Access 2000 network;

a Universal Mobile Telecommunications System Terrestrial Radio Access Network;

a Global System for Mobile Communications (GSM) network;
