Abstract

Claims (32)

1. A method performed an electronic device in a communication network having an access network that is a Universal Mobile Telecommunications System (UMTS) access network, the method bypassing a radio network controller that receives and transmits a data stream in a communication network, the data stream comprising a first data channel and a second data channel, the method comprising:

receiving at least the second data channel at a location upstream of the radio network controller in the UMTS access network such that the second data channel is not provided to the radio network controller, the second data channel comprising data in a format that is compatible with the radio network controller;

processing, using at least one of the electronic devices, the second data channel to create a bypass data channel, the bypass data channel comprising data in a bypass format; and

forwarding the bypass data channel to a location downstream of the radio network controller in the UMTS access network.

2. The method of claim 1 , wherein processing the second data channel comprises ciphering the second data channel.

3. The method of claim 1 , wherein processing the second data channel comprises compressing the second data channel.

4. The method of claim 1 , wherein the bypass device emulates an RNC protocol stack.

5. The method of claim 1 , wherein the location upstream of the radio network controller in the UMTS access network is provided on an IuPS interface, and the location downstream of the radio network controller in the UMTS access network is provided on an IuB interface.

6. An electronic device readable storage medium storing executable instructions for performing a method in an electronic device in a communication network having an access network that is a Universal Mobile Telecommunications System (UMTS) access network, the method bypassing a radio network controller that receives and transmits a data stream in a communication network, the data stream comprising a first data channel and a second data channel, the instructions executable by one or more processors to cause the one or more processors to:

receive the first data channel and the second data channel at a location upstream of the radio network controller in the UMTS access network, the second data channel comprising data in a format that is compatible with the radio network controller;

select data in the first data channel and provide the data in the first data channel to the radio network controller;

process the second data channel to create a bypass data channel, the bypass data channel comprising data in a bypass format; and

forward the bypass data channel to a location downstream of the radio network controller in the UMTS access network.

7. The method of claim 6 , wherein processing the second data channel comprises ciphering the second data channel.

8. The method of claim 6 , wherein processing the second data channel comprises compressing the second data channel.

9. The method of claim 6 , wherein the bypass device emulates an RNC protocol stack to place the data in the bypass format.

10. The method of claim 6 , wherein the location upstream of the radio network controller in the UMTS access network is provided on an IuPS interface, and the location downstream of the radio network controller in the UMTS access network is provided on an IuB interface.

11. A system for use in a communication network having a Universal Mobile Telecommunications System (UMTS) access network, the system bypassing a radio network controller that receives and transmits a data stream in the UMTS access network, the data stream comprising a first data channel and a second data channel, the system comprising:

a bypass device, the bypass device comprising

a storage for storing instructions and data; and

one or more processors for executing instructions, the instructions causing the one or more processors to:

intercept at least the second data channel at a location upstream of the radio network controller in the access network such that the second data channel is not provided to the radio network controller, the second data channel comprising data in a format that is compatible with the radio network controller,

process the second data channel to create a bypass data channel, the bypass data channel comprising data in a bypass format, and

forward the bypass data channel to a location downstream of the radio network controller in the UMTS access network.

12. The system of claim 11 , further comprising a remote node located at the location downstream of the radio network controller in the UMTS access network, the remote node comprising:

a storage for storing instructions and data; and

one or more processors for executing instructions, the instructions causing the one or more processors to:

receive the bypass data channel at the location downstream of radio network controller and processing the bypassed data channel to create data in a format that is compatible with a base station in the UMTS access network, and

forward the data in the format that is compatible with the base station towards the base station.

13. The system of claim 11 , wherein processing the second data channel comprises one of the group of ciphering the second data channel and compressing the second data channel.

14. The system of claim 11 , wherein the bypass device emulates an RNC protocol stack to place the data in the bypass format.

15. The system of claim 11 , wherein, the location upstream of the radio network controller in the UMTS access network is provided on an IuPS interface, and the location downstream of the intermediate service platform in the access network is provided on an IuB interface.
