Definitions
- This invention relates to a method and apparatus for testing a mobile telephone terminal.
- Known mobile terminal testers implement most of the communications protocol that a base station would use to communicate with the terminal, and interact with the terminal so as to measure its performance, for example, in terms of bit error rate and modulation quality. These testers are therefore relatively complicated both in terms of their hardware and software.
- An object of the invention therefore is to provide a simplified method and apparatus for testing mobile telephone terminals.
- test apparatus does not therefore need to incorporate the associated hardware or software.
- Figure 1 illustrates a conventional mobile ratio test set
- Figure 2 illustrates a test set according to the invention
- FIG. 3 illustrates an alternative embodiment of the invention. Embodiments of the Invention
- the architecture required for a conventional mobile radio test set comprises the following:
- the MMI at the top of the tree This usually includes some form of display to inform the user of the current instrument and test status. Keys allow the user to implement the chosen test.
- Layer 3 protocol This layer forms messages for the mobile and interprets messages from the mobile.
- Layer 2 protocol This layer's job is to ensure reliable transmission and reception of messages from/to Layer 3. For example, when sending a message to the mobile a response is usually made. If Layer 2 does not hear this response it will retransmit the message, on the assumption that the original transmission was not successful.
- Layer lb protocol A subset of Layer 1. On the downlink this layer takes the Layer 2 blocks and applies channel encoding to aid successful transmission on the air interface. On the uplink the reverse happens and channel decoding is used to reveal the Layer 2 message from the mobile.
- Layer la protocol (a subset of Layer 1): On the downlink this layer takes the binary information from Layer lb and modulates it to give baseband I and Q samples. For the uplink this layer receives IQ samples and demodulates them back to binary values.
- IQ modulator On the downlink this takes the baseband IQ generated by Layer 1 and forms a signal at the correct carrier frequency using a local oscillator L01.
- IQ demodulator The reverse of the IQ modulator - it takes the modulated carrier and derives IQ at baseband using a local oscillator L02.
- RF combiner where RF transmit/receive paths are combined into a single connection 9 of the antenna of the mobile telephone.
- BCCH Broadcast Control Channel
- FCCH Frequency Control Channel
- the mobile 10 uses the FCCH and SCH to synchronise to the test set emulation of a basestation, allowing it to demodulate and interpret the System Information Messages. Once it has done this, it may attempt to register with the test set. This registration process is initiated by the mobile 10 when it sends an Access burst on the Random Access Channel on the uplink 12.
- the test set demodulates the Access burst and responds. A brief series of messages pass between the test set and mobile as they exchange and verify system information.
- the invention simplifies the test set architecture by appreciating that a considerable amount of testing can be done by simply getting the mobile 10 to send an Access burst on the Random Access Channel.
- the invention achieves this with the architecture as illustrated in Figure 2.
- the IQ modulator 6 remains with its associated Local Oscillator (LO1), but the IQ data applied to it is no longer coming from a conventional Layer 1, 2, 3 arc tecture. Instead, a fixed Broadcast Control Channel is stored in a memory 13 as IQ samples. These are clocked out by an address generator 14 and applied to the IQ modulator 6.
- LO1 Local Oscillator
- the predetermined pattern may be generated using a subset of the protocol stack 2 to 5, for example, stored data symbols may be processed by a baseband modulator, which is a subset of Layer la, before being applied to the IQ modulator 6.
- the mobile 10 responds to the fixed BCCH by sending an Access burst but it does not get a reply.
- the test set uses a power detector 15 to determine whether the mobile makes a transmission and this may be indicated to the user on a display 16.
- the power detector 15 may simply determine whether or not the transmission power is above a threshold level or may determine the actual transmission power level and report this to the display 16.
- the access burst may be captured by a radio frequency receiver and analysed.
- the analysis may determine modulation quality, such as vector value, and report this or a comparison with allowable limits; or the analysis may determine spectral characteristics, such as adjacent channel power, occupied bandwidth and spurious signals, and report this or the comparison with allowable limits; or the analysis may determine the power envelope against time and compare this with a mask defining upper and lower allowable limits.
- the information in the stored BCCH tells the mobile the power level at which to transmit its Access burst, and the number of burst retries to perform. So, a number of different BCCH can be stored and selected to test the mobile's power level control.
- test set may be connected directly to an antenna connector on the mobile phone 10 using a cable 9, as in the prior art of Figure 1.
- the coupler 17 makes a connection to the mobile 10 over the air interface rather than through a piece of cable. As such, the coupler 17 and mobile 10 may need to be screened from other signals as shown by screening 18 in Figure 3. This makes sure that the mobile can only hear the test set signal. This approach then allows the test set to verify that the mobile's antenna is functioning correctly.
- test set according to the invention is simpler, cheaper and more robust which makes it suitable for widespread use, for example, in retail outlets which sell mobile telephones.
- the retail outlets can then check a mobile to see if it is faulty before returning it to a more expensive repair centre.
