Method, apparatus and system for testing user equipment functionality
View Patent ↗Aspects of the present invention include methods, apparatuses and systems that may be used for radio frequency and performance testing of communication equipment in a telecommunications network. According to one aspect of the invention, received data may be discarded during a test whenever a device being testing is unable to store the data, for example in a buffer. According to another aspect of the invention, the device being tested will provide data for transmission processing whenever there is an opportunity during the testing to transmit data, thus allowing the device to be aggressive in its data transmission.
1. A method, comprising:
establishing a size limit for a buffer configured to store at least one data unit during a testing event in a mobile telecommunications network, wherein the testing event occurs during operation of a user equipment comprising the buffer with the mobile telecommunications network to determine whether the user equipment is capable of supporting enhanced dedicated channel and meeting performance requirements,
wherein the establishing the size limit for the buffer is based on a multiple of a maximum number of bits of an enhanced dedicated channel transport block, that can be transmitted in a transmission time interval (TTI), by a predetermined constant,
receiving a data unit from a system simulator,
determining if the data unit received during the testing event and an amount of data units present in the buffer will exceed the size limit, and
discarding at least part of the received data unit during the testing event when the received data unit and the amount of data units present in the buffer will exceed the size limit of the buffer,
recognizing an opportunity for enhanced dedicated channel data transmission during the testing event in the mobile telecommunications network,
removing enhanced dedicated channel data from the buffer, and processing the data for enhanced dedicated channel transmission; and transmitting at least part of the data to the system simulator via the enhanced dedicated channel.
2. The method according to claim 1 , wherein the establishing the size limit for the buffer is based on at least one capability of the user equipment comprising the buffer.
3. A computer program product comprising a non-transitory computer readable storage medium embodying computer program code thereon for execution by a computer processor is provided, wherein the computer program code comprises instructions for performing a method according to claim 1 .
4. An apparatus, comprising:
an establishment module for establishing a size limit of a buffer configured for storage of at least one data unit during a testing event in a mobile telecommunications network, wherein the testing event occurs during operation of the apparatus with the mobile telecommunications network to determine whether the apparatus is capable of supporting enhanced dedicated channel and meeting performance requirements,
wherein the establishing the size limit for the buffer is based on a multiple of a maximum number of bits of an enhanced dedicated channel transport block, that can be transmitted in a transmission time interval (TTI), by a predetermined constant;
a receiver for receiving a data unit from a system simulator;
a comparator for determining if the data unit received during the testing event and an amount of data units present in the buffer will exceed the size limit; and
a discarder for discarding at least part of the received data unit during the testing event when the received data unit and the amount of data units present in the buffer will exceed the size limit of the buffer;
a recognizer for recognizing an opportunity for enhanced dedicated channel data transmission during the testing event in the mobile telecommunications network,
a remover for removing enhanced dedicated channel data from the buffer, and processing the data for enhanced dedicated channel transmission; and transmitting at least part of the data to the system simulator via the enhanced dedicated channel.
5. The apparatus according to claim 4 , wherein the establishment module is configured to establish the size limit for the buffer based at least on at least one capability of the apparatus comprising the buffer.
6. A system, comprising:
a system simulator configured to transmit at least one data unit during a testing event in a mobile telecommunications network, wherein the testing event occurs during operation of a user equipment (UE) comprising a buffer with the mobile telecommunications network to determine whether the user equipment (UE) is capable of supporting enhanced dedicated channel and meeting performance requirements, and
the user equipment is configured to establish a size limit for the buffer, wherein the establishing the size limit for the buffer is based on a multiple of a maximum number of bits of an enhanced dedicated channel transport block, that can be transmitted in a transmission time interval (TTI), by a predetermined constant, and the user equipment configured to receive the at least one data unit,
wherein the user equipment is configured to determine if the data unit received during the testing event and an amount of data units present in the buffer will exceed the size limit, and to discard at least part of the received data unit during the testing event when the received data unit and the amount of data units present in the buffer will exceed the size limit of the buffer,
wherein the user equipment terminal is configured to recognize an opportunity for enhanced dedicated channel data transmission during the testing event in the mobile telecommunications network, and
wherein the user equipment is configured to remove enhanced dedicated channel data from the buffer, and to process the data for enhanced dedicated channel transmission; and to transmit at least part of the data to the system simulator via the enhanced dedicated channel.
