Abstract

A method for performing mobile communications may include receiving a first multimedia broadcast or multicast stream from a serving cell; determining whether or not a neighbor cell is capable of providing the first multimedia broadcast or multicast stream to generate a first determination result; and initiating neighbor cell protocol operations with the neighbor cell according to a first set of threshold criteria if the first determination result is negative and initiating neighbor cell protocol operations with the neighbor cell according to a second set of threshold criteria if the first determination result is positive. The neighbor cell protocol operations are cell measurements of the neighbor cell or cell reselection to the neighbor cell.

First claim

What is claimed is:

1 . A mobile radio communication terminal device comprising:
a receiver configured to receive a first multimedia broadcast or multicast stream from a serving cell; and a processing circuit configured to: determine whether or not a neighbor cell is capable of providing the first multimedia broadcast or multicast stream to generate a first determination result; and initiate one or more neighbor cell protocol operations with the neighbor cell according to a first set of threshold criteria if the first determination result is negative and to initiate one or more neighbor cell protocol operations with the neighbor cell according to a second set of threshold criteria if the first determination result is positive, wherein the one or more neighbor cell protocol operations are one or more cell measurements of the neighbor cell or cell reselection to the neighbor cell.

2 . The mobile radio communication terminal device of claim 1 , wherein the processing circuit is configured to:
determine a positive first determination result if the neighbor cell is capable of providing the first multimedia broadcast or multicast stream; and determine a negative first determination result if the neighbor cell is not capable of providing the first multimedia broadcast or multicast stream.

3 . The mobile radio communication terminal device of claim 1 ,
wherein the second set of threshold criteria comprises a network-provided signal power threshold and a network-provided signal quality threshold.

4 . The mobile radio communication terminal device of claim 1 , further comprising:
a signal measurement circuit configured to measure a signal power of a wireless signal received from the serving cell, and wherein the processing circuit is configured to initiate one or more neighbor cell protocol operations with the neighbor cell according to a first set of threshold criteria if the first determination result is negative by: performing one or more cell measurements of the neighbor cell if the measured signal power is less than a signal power measurement threshold of the first set of threshold criteria and greater than a signal power reselection threshold of the first set of threshold criteria; and performing cell reselection to the neighbor cell if the measured signal power is less than the signal power reselection threshold of the first set of threshold criteria.

5 . The mobile radio communication terminal device of claim 4 , wherein the signal power measurement threshold is greater than the signal power reselection threshold.

6 . The mobile radio communication terminal device of claim 1 , further comprising:
a signal measurement circuit configured to measure a signal quality of a wireless signal received from the serving cell, and wherein the processing circuit is configured to initiate one or more neighbor cell protocol operations with the neighbor cell according to a first set of threshold criteria if the first determination result is negative by: performing one or more cell measurements of the neighbor cell if the measured signal quality is less than a signal quality measurement threshold of the first set of threshold criteria and greater than a signal quality reselection threshold of the first set of threshold criteria; and performing cell reselection to the neighbor cell if the measured signal quality is less than the signal quality reselection threshold of the first set of threshold criteria.

7 . The mobile radio communication terminal device of claim 1 , further comprising:
an error correction circuit configured to measure a block error rate of the first multimedia broadcast or multicast stream, and wherein the processing circuit is configured to initiate one or more neighbor cell protocol operations with the neighbor cell according to a first set of threshold criteria if the first determination result is negative by: performing one or more cell measurements of the neighbor cell if the measured block error rate is less than a block error rate measurement threshold of the first set of threshold criteria and greater than a block error rate reselection threshold of the first set of threshold criteria; and performing cell reselection to the neighbor cell if the measured block error rate is less than the block error rate reselection threshold of the first set of threshold criteria.

8 . The mobile radio communication terminal device of claim 1 , further comprising
a signal decoding circuit configured to measure a decoding quality of the first multimedia broadcast or multicast stream, and wherein the processing circuit is configured to initiate one or more neighbor cell protocol operations with the neighbor cell according to a first set of threshold criteria if the first determination result is negative by: performing one or more cell measurements of the neighbor cell if the measured decoding quality is less than a decoding quality measurement threshold of the first set of threshold criteria and greater than a decoding quality reselection threshold of the first set of threshold criteria; and performing cell reselection to the neighbor cell if the measured decoding quality is less than the decoding quality reselection threshold of the first set of threshold criteria.

9 . The mobile radio communication terminal device of claim 1 , further comprising:
one or more measurement circuits configured to measure one or more signal characteristics of a wireless signal received from the serving cell, and wherein the processing circuit is configured to initiate one or more neighbor cell protocol operations with the neighbor cell according to a first set of threshold criteria if the first determination result is negative by: comparing the one or more signal characteristics to the first set of threshold criteria; and performing one or more cell measurements of the neighbor cell or performing cell reselection to the neighbor cell based on whether the one or more signal characteristics meets the first set of threshold criteria.
