## Abstract

A method of providing position assistance to a UE, the method comprising providing, by a location server, at least one unsolicited message, each message comprising one of data selected from a list comprising GNSS ephemeris assistance data, GNSS acquisition assistance data, OTDOA assistance data and eNB position data for a predefined area.

## Claims

### Claim 1

A method of providing position assistance to a UE, the method comprising:
providing, by a location server, at least one unsolicited message, each message comprising one of data selected from a list comprising:
GNSS ephemeris assistance data;
GNSS acquisition assistance data;
OTDOA assistance data; and
eNB position data for a predefined area.

### Claim 2

A method of receiving position assistance, the method comprising:
receiving, at a UE, at least one unsolicited message, each message comprising one of data selected from a list comprising:
GNSS ephemeris assistance data;
GNSS acquisition assistance data;
OTDOA assistance data; and
eNB position data for a predefined area.

### Claim 3 (depends on 1)

The method of claim 1 wherein the ephemeris assistance data comprises ephemeris data, time data and/or almanac data.

### Claim 4 (depends on 1)

The method of claim 1 wherein the GNSS acquisition assistance data comprises expected phase and/or Doppler ranges.

### Claim 5 (depends on 1)

The method of claim 1 wherein the OTDOA assistance data comprises a list of eNB, associated PRS pattern and/or expected RSTD range.

### Claim 6 (depends on 1)

The method of claim 1 wherein the eNB position data comprises eNB position data of an area adjacent or surrounding a cell or base station of a wireless communications network; and optionally wherein the cell or base station is an LTE cell or base station.

### Claim 7 (depends on 1)

The method of claim 1 wherein the at least one unsolicited message is provided on an LTE control plane or user plane.

### Claim 8 (depends on 1)

The method of claim 1 wherein the at least one unsolicited message is broadcast per LTE cell.

### Claim 9 (depends on 8)

The method of claim 8 wherein the at least one unsolicited message is broadcast to each UE attached to an eNB.

### Claim 10 (depends on 1)

The method of claim 1 wherein the at least one unsolicited message further comprises reliability data defining a reliability of the message data; and optionally wherein
the reliability data is indicative of a period of time when the at least one unsolicited message data can be considered reliable; and/or optionally
wherein the reliability data comprises a geographical area of applicability of the at least one unsolicited message data.

### Claim 11 (depends on 1)

The method of claim 1 wherein the position assistance is provided to an LTE UE without requiring the UE to be attached to an LTE network.

### Claim 12

(canceled)

### Claim 13

(canceled)

### Claim 14

(canceled)

### Claim 15

(canceled)

### Claim 16 (depends on 2)

The method of claim 2 wherein the ephemeris assistance data comprises ephemeris data, time data and/or almanac data.

### Claim 17 (depends on 2)

The method of claim 2 wherein the GNSS acquisition assistance data comprises expected phase and/or Doppler ranges.

### Claim 18 (depends on 2)

The method of claim 2 wherein the OTDOA assistance data comprises a list of eNB, associated PRS pattern and/or expected RSTD range.

### Claim 19 (depends on 2)

The method of claim 2 wherein the eNB position data comprises eNB position data of an area adjacent or surrounding a cell or base station of a wireless communications network; and optionally wherein the cell or base station is an LTE cell or base station.

### Claim 20 (depends on 2)

The method of claim 2 wherein the at least one unsolicited message is provided on an LTE control plane or user plane.

### Claim 21 (depends on 2)

The method of claim 2 wherein the at least one unsolicited message is broadcast per LTE cell.

### Claim 22 (depends on 21)

The method of claim 21 wherein the at least one unsolicited message is broadcast to each UE attached to an eNB.

### Claim 23 (depends on 2)

The method of claim 2 wherein the at least one unsolicited message further comprises reliability data defining a reliability of the message data; and optionally wherein
the reliability data is indicative of a period of time when the at least one unsolicited message data can be considered reliable; and/or optionally
wherein the reliability data comprises a geographical area of applicability of the at least one unsolicited message data.

### Claim 24 (depends on 2)

The method of claim 2 wherein the position assistance is provided to an LTE UE without requiring the UE to be attached to an LTE network.
