## Abstract

A method and apparatus for implementing ProSe (Proximity Services) are disclosed. The method includes using ProSe communication with direct mode data path. The method also includes sending a request to an eNB (evolved Node B) to establish ProSe communication with locally-routed data path.

## Claims

### Claim 1

A method for implementing ProSe (Proximity Services) in a UE (User Equipment), comprising:
using ProSe communication with direct mode data path; and
sending a request to an eNB (evolved Node B) to establish ProSe communication with locally-routed data path.

### Claim 2 (depends on 1)

The method of claim 1, wherein the UE sends the request to switch a data path of ProSe communication from direct mode data path to locally-routed data path.

### Claim 3 (depends on 1)

The method of claim 1, wherein the UE sends the request when the direct mode data path is considered not reliable or no longer feasible.

### Claim 4

A method for implementing ProSe (Proximity Services) in an eNB (evolved Node B), comprising:
establishing ProSe communication with locally-routed data path for a UE when receiving a request from the UE that is using ProSe communication with direct mode data path.

### Claim 5 (depends on 4)

The method of claim 4, wherein the eNB switches a data path of ProSe communication from direct mode data path to locally routed data path.

### Claim 6 (depends on 1)

The method of claim 1, wherein the ProSe communication with locally-routed data path is the ProSe communication via one or more eNBs.

### Claim 7 (depends on 1)

The method of claim 1, wherein the ProSe communication with direct mode data path is the ProSe communication via the direct link between the UE and its peer UE.

### Claim 8 (depends on 1)

The method of claim 1, wherein the request to the eNB includes an identity of a peer UE of the ProSe communication, an identity of a data session involved in the ProSe communication, and/or an identity of a service (or application) involved in the ProSe communication.

### Claim 9 (depends on 1)

The method of claim 1, wherein the UE is ProSe-enabled, is authorized and/or authenticated for using the proximity services, and/or is in connected mode.

### Claim 10 (depends on 3)

The method of claim 3, wherein the direct mode data path is considered not reliable or no longer feasible when a radio problem or a radio link failure is detected on the direct mode data path.

### Claim 11

A communication device to implement ProSe (Proximity Services) in a UE (User Equipment), the communication device comprising:
a control circuit;
a processor installed in the control circuit;
a memory installed in the control circuit and operatively coupled to the processor;
wherein the processor is configured to execute a program code stored in the memory to:
use ProSe communication with direct mode data path; and
send a request to an eNB (evolved Node B) to establish ProSe communication with locally-routed data path.

### Claim 12 (depends on 11)

The communication device of claim 11, wherein the UE sends the request to switch a data path of ProSe communication from direct mode data path to locally-routed data path.

### Claim 13 (depends on 11)

The communication device of claim 11, wherein the UE sends the request when the direct mode data path is considered not reliable or no longer feasible.

### Claim 14 (depends on 11)

The communication device of claim 11, wherein the ProSe communication with direct mode data path is the ProSe communication via the direct link between the UE and its peer UE.

### Claim 15 (depends on 11)

The communication device of claim 11, wherein the ProSe communication with locally-routed data path is the ProSe communication via one or more eNBs.

### Claim 16 (depends on 11)

The communication device of claim 11, wherein the request to the eNB includes an identity of a peer UE of the ProSe communication, an identity of a data session involved in the ProSe communication, and/or an identity of a service (or application) involved in the ProSe communication.

### Claim 17 (depends on 11)

The communication device of claim 11, wherein the UE is ProSe-enabled, is authorized and/or authenticated for using the proximity services, and/or is in connected mode.

### Claim 18 (depends on 11)

The communication device of claim 11, wherein the direct mode data path is considered not reliable or no longer feasible when a radio problem or a radio link failure is detected on the direct mode data path.
