Abstract

Channels are allocated to base stations in a telecommunications network for communications with mobile user terminals. Interference is measured on each channel used by a respective base station. The measured interference value for that channel and base station is added to an interference record. Channels are allocated to the base stations for further communications dependent upon the recorded interference.

Claims

1. A method of allocating channels to base stations in a telecommunications network for communications with mobile user terminals, the method comprising:

measuring interference on each channel used by a respective base station,

adding the measured interference value for that channel and base station to an interference record, and

allocating channels to the base stations for further communications dependent upon the recorded interference.

2. The method according to claim 1, wherein the interference record is a matrix of total measured interference for each channel and base station combination used.

3. The method according to claim 2, wherein the matrix α

_jk, contains the total measured interference when a base station j uses a channel k, and follows α

_jk=α

<sub>jk(t−

1)</sub>+I_jkt where α

_jkt is the matrix α

_jk at time t, α

<sub>jk(t−

1)</sub> is the matrix α

_jk at earlier time t−

1, and I_jkt is the interference measured by the base station j on the channel k at time t.

4. The method according to claim 1, wherein the communications are call connections.

5. The method according to claim 4, wherein for call connection with a mobile user terminal, the base station having that mobile user terminal in its cell is allocated the channel having the lowest recorded total interference among those channels available to the base station.

6. A telecommunications network comprising base stations for communications with mobile user terminals, the base stations being operative to measuring interference on each channel they use, and the network further comprising a base station controller connected to the base stations and operative to record the measured interference values for each channel and base station combination used in an interference record and to allocate channels to the base stations for further communications dependent upon the recorded interference.

7. A network according to claim 6, wherein the interference record is a matrix of total measured interference for each channel and base station combination used.

8. The network according to claim 7, wherein the matrix α

_jk, contains the total measured interference when a base station j uses a channel k, and follows α

_jkt=α

<sub>jk(t−

1)</sub>+I_jkt where α

_jkt is the matrix α

_jk at time t, α

<sub>jk(t−

1)</sub> is the matrix α

_jk at earlier time t−

1, and I_jkt is the interference experienced by the base station j on the channel k at time t.

9. The network according to claim 6, wherein said communications are call connections.

10. The network according to claim 9, wherein for a call-connection with a mobile user terminal, the base station having that mobile user terminal in its cell is allocated by the base station controller the channel having the lowest recorded total interference among those channels available to the base station.
