## Abstract

A method and apparatus for establishing a direct connection in a ProSe (Proximity Services) communication system are disclosed. The method includes a first UE initiating a direct connection with a second UE and receiving a CID (Connection Identifier) from an administration entity of the ProSe communication system, wherein the CID is used for identifying the direct connection. The method further includes the administrative entity of the ProSe communication system receiving a request from a first UE (User Equipment) to establish a direct connection with a second UE and sending a CID (Connection Identifier) to a first UE connection, wherein the CID is used for identifying the direct connection.

## Claims

### Claim 1

A method for establishing a direct connection in a ProSe (Proximity Services) communication system, comprising:
a first UE (User Equipment) initiates a direct connection with a second UE; and
the first UE receives a CID (Connection Identifier) from an administration entity of the ProSe communication system, wherein the CID is used for identifying the direct connection.

### Claim 2 (depends on 1)

The method of claim 1, wherein the first UE communicates with the administration entity via an infrastructure connection.

### Claim 3 (depends on 1)

The method of claim 1, wherein a data path of the direct connection goes directly between the first UE and the second UE without via any network node.

### Claim 4 (depends on 1)

The method of claim 1, wherein the first UE communicates with the second UE via radio resources allocated for the CID.

### Claim 5 (depends on 1)

The method of claim 1, wherein radio resources for the ProSe communication system are configured in system information of a cell.

### Claim 6

A method for establishing a direct connection in a ProSe (Proximity Services) communication system, comprising:
an administrative entity of the ProSe communication system receives a request from a first UE (User Equipment) to establish a direct connection with a second UE; and
the administrative entity sends a CID (Connection Identifier) to the first UE, wherein the CID is used for identifying the direct connection.

### Claim 7 (depends on 6)

The method of claim 6, wherein the administration entity communicates with the first UE via an infrastructure connection.

### Claim 8 (depends on 6)

The method of claim 6, wherein a data path of the direct connection goes directly between the first UE and the second UE without via any network node.

### Claim 9 (depends on 6)

The method of claim 6, wherein radio resources for the ProSe communication system are configured in system information of a cell.

### Claim 10

A communication device for establishing a direct connection in a ProSe (Proximity Services) communication system, 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 memory to establish the direct connection by:
initiating, at a first UE (User Equipment), a direct connection with a second UE; and
receiving, at the first UE, a CID (Connection Identifier) from an administration entity of the ProSe communication system, wherein the CID is used for identifying the direct connection.

### Claim 11 (depends on 10)

The communication device of claim 10, wherein the first UE communicates with the administration entity via an infrastructure connection.

### Claim 12 (depends on 10)

The communication device of claim 10, wherein a data path of the direct connection goes directly between the first UE and the second UE without via any network node.

### Claim 13 (depends on 10)

The communication device of claim 10, wherein the first UE communicates with the second UE via radio resources allocated for the CID.

### Claim 14 (depends on 10)

The communication device of claim 10, wherein radio resources for the ProSe communication system are configured in system information of a cell.
