Description of the prior art

In the field of radio communications there are a number of technology-based standards for managing communication sessions between the mobile station, such as a cell phone, the device is a personal communication system (PSS), or other subscriber by means of remote communication and the base station. These standards include the standards as digital and analog communications. Among the standards of digital communication for cellular communication may be called the standards of the series IS-95, developed by the Association of the industry of telecommunications and electronics industry Association (TIA/EIA), which includes standards IS-95A and is-95B called "Standard compatibility of the mobile station and a base station for dual-mode cellular system with expansion of the range". Among digital standards for PSS there are a number of standards series J-STD-008 American national standards Institute (ANSI), entitled "compliance to the personal station and the base station for personal communication systems operating at a frequency of 1.8 and 2.0 GHz on the principle of multiple access kodovym channelized (mdcr)".

Other digital standards, not related to mdcr include Global system for mobile communications (GSM), built on the principle of multiple access time division channels (MDR), and the U.S. standard TIA/EIA-series IS-54 on the principles mdvr.

The method of modulation with the expansion of the range used in mdcr, has significant advantages compared with other methods of modulation for communication systems with multiple access. Methods mdcr in the communication system with multiple access described in U.S. patent No. 4901307, issued February 13, 1990 on the invention of "communication System with multiple access spread spectrum using satellite or terrestrial repeaters", the right to which is assigned to the assignee of the present invention and which is mentioned here for details.

Space diversity or diversity of tracks is achieved by providing multiple routes signal for simultaneous lines of communication from the mobile subscriber through two or more cell site. In addition, the diversity of tracks can be provided by using an environment with multipath propagation by processing spread spectrum with separate receiving and processing a signal arriving with different delays in distribution. Examples explode slopes polluter is arranged in U.S. patent No. 5101501, issued March 31, 1992, for an invention of "Soft switching of communication channels in a cellular telephone system mdcr" and U.S. patent No. 5109390, issued April 28, 1992, for the invention "Receiver with diversity in a cellular telephone system mdcr", the rights to which are assigned to the assignee of the present invention and which are referred to here for details.

The adverse effect of fading can be to some extent additional control in the system mdcr by adjusting the transmitter power. In U.S. patent No. 5056109, issued October 8, 1991, for the invention "Method and apparatus for controlling the transmission power in the system mobile phone mdcr" on the application 07/433031, filed November 7, 1989, the right to which is assigned to the assignee of the present invention and which is mentioned here for the information described system power control cell site and mobile device. Methods mdcr in the communication system with multiple access is also described in U.S. patent No. 5103459, issued April 7, 1992, for the invention "System and method for generating signals in a cellular telephone system mdcr", the right to which is assigned to the assignee of the present invention and which is mentioned here for details.

In all of the above patents describes the use of the pilot signal is La occurrences in synchronism in the system radio mdcr. At different times when the machine is powered radio, such as a cellular phone or device operates, it is subjected to the procedure of entering into synchronism, which includes, among other things, search, and detection signal of the pilot channel from the base station in the communication system. For example, in more detail demodulation and occurrence in synchronism with the control channel in the system mdcr described in co-pending application, U.S. 08/509721 for the invention "Method and apparatus for searching and entering into synchronism in the communication system mdcr", the rights to which are assigned to the assignee of the present invention and which is mentioned here for information. If the radio communications device can log in synchronism with more than one pilot channel, it selects the pilot channel with the strongest signal. After the establishment of synchronism with the pilot-channel radio communications device receives the possibility of its occurrence in synchronism with additional channels from the base stations, which are necessary for communication. The structure and function of these other channels are described in more detail in the aforementioned U.S. patent No. 5103469 and not described here in detail.

The procedure of entering in synchronism to search for and capture signals the pilot channel from the base station is finding potential base station candidates for the lane is exceptionally communication channels. The base station, which is viable candidates can be divided into four groups. These groups are used to rank the control channels according to the priority and improve the efficiency of search. The first group, referred to as the active set contains the base stations that are currently connected with the mobile station. The second group, called the set of candidates contains a base station in respect of which it was found that they have a sufficient signal level to use this base station. Base stations are added to the set of candidates when the measured energy of the pilot channel exceeds the specified threshold TADD. The third group is the set of neighbors, i.e. the set of base stations that are near from this mobile station (not included in the active set or the set of candidates). And fourth, or set other stations, form all other base stations.

In the communication system IS-95A mobile station sends an offline message level measurement pilot channel (SIPC), when she finds the pilot channel with a sufficient level that is not associated with any of the direct channels of traffic, demodulating at the moment, or when the level of the pilot channel associated with one of demodulating direct channels of traffic falls below a certain threshold for a given the th time interval. The concept of "pilot channel" refers to the pilot channel, identified by the shift of the pilot sequence and assignment of frequencies. The mobile station sends an offline SIPC after detecting changes in the level of the pilot channel when satisfied one of the following conditions:

1. Found that the level of the pilot channel of the set of neighbors or set other stations exceeds the threshold (TADD).

2. The level of the pilot channel of the set of candidates exceeds the level of the pilot channel in the active set by the value exceeds the threshold (TThe OMRS)×0.5 dB, and SIPC carrying this information has not been sent since then, as it was the last message about the direction of switching of the communication channels (SNP) or an extended message about the direction of switching of the communication channels (RSNP).

3. The level of the pilot channel in the active set or the set of candidates fell below a certain threshold (TDROP) more than a specified interval of time (TTDROP), and SIPC carrying this information has not been sent since then, as it was the last SNP or RNP.

TADDis the threshold above which the received signal has a sufficient level to ensure effective communication with this mobile station. TDROPis the threshold below which the energy of the received signal is insufficient for effective communication with podi the Noi station.

In the communication system IS-95B mobile station sends Autonomous SIPC in accordance with one of the two sets of rules, the selected base station. The first set of rules are identical to rules established in the standard IS-95A. The second set of rules uses a dynamic threshold, which is defined as follows

where the parameters SOFT_SLOPE and ADD_INTERCEPT set the base station and the summation is performed for all the pilot channels in the active set. Ec/Io is the ratio of the energy of the pilot channel on one element of the signal-to-total adopted spectral density of noise and signals.

According to the second set of rules IS-95A mobile station sends Autonomous SIPC if one of the following conditions:

1. Found that the level of the pilot channel of the set of candidates exceeds TDYNand SIPC carrying this information has not been sent since then, as it was the last RSNP or a General message about the direction of switching of the communication channels (OSNP).

2. Found that the level of the pilot channel of the set of neighbors or set other stations exceeds max (TDYN, TADD/2).

3. The level of the pilot channel of the set of candidates exceeds the level of any pilot channel active set at TCOMP×0.5 dB and above TDYNand SIPC carrying this information has not been sent since then, as has been the principle is the last message RSNP or ONP.

4. Expired timer reset switch communication channels pilot channel in the active set, and SIPC carrying this information has not been sent since then, as it was the last RSNP or ONP.

Rules according to the standards of IS-95A and is-95B developed for systems with a single carrier, which uses the channel is 1.25 MHz on both straight and on the return line. However, in a multi-carrier mobile station receives the pilot channel of a base station simultaneously on multiple carrier frequencies. For example, in a system with multiple carriers 3X/1X can be used three channels of 1.25 MHz in a straight line and one channel of 1.25 MHz in the return line. Another example is a system with several carriers 3/3, which uses three channels of 1.25 MHz in a straight line and the channel 3.75 MHz on the return line. In any of these examples may be short-term fading, different on different carrier frequencies. In this situation, the rule IS-95, guiding Autonomous transmission SIPC not suitable in the presence of the pilot channels in multi-carrier pilot channel. Therefore, there is a need to identify when the mobile station transmits Autonomous SIPC according to the reception of signals from several pilot channels from the base stations in multi-carrier systems.

The invention

The basis for this is the future of the invention is to provide a method and device for the formation of the Autonomous message level measurement pilot channel (SIPC), the mobile station in the communication system with multiple carriers, in which the mobile station take multiple pilot channels transmitted from at least one base station; use the first definition of the level of the pilot channel from the group of definitions level of the pilot channel to determine the signal strength of the pilot channel associated with at least one of the multiple pilot channels; verify the set of rules for building SIPC, by manipulating the first determining signal strength of the pilot channel and form SIPC for transmission from the mobile station.

In one aspect of the invention the set of rules used different definitions of the signal level of the pilot channel by applying one definition of the signal level of the pilot channel in the same rule, and applying a different definition of the signal level of the pilot channel in a different rule. In another aspect of the invention SIPC generated by the mobile station, carries information about the signal level of the pilot channel, which was not used for the formation of SIPC.

Detailed description of preferred the equipment of embodiments of the invention

Figure 1 shows a sample of a radio communication system that implements the present invention. In a preferred embodiment of the invention, the communication system uses a radio system mdcr, although it should be understood that this invention is equally applicable to other types of communication systems. The present invention can be used in systems that employ other well-known modulation scheme of the transmission, such as MDR and FDMA equipment, as well as in other systems with spread spectrum.

As shown in figure 1, the radiotelephone system mdcr contains lots of mobile subscriber devices (stations) 10, the set of base stations 12, base station controllers (ASC) 14 and the switch-node mobile (WKS) 16. UKPC 16 is configured to mate with a conventional telephone network (PSTN) 18. UKPC 16 is also configured to mate with ASC 14. ASC 14 is connected to the base stations 12 via a relay line. Relay line can be configured to support any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. It is clear that the system can be more than two KBS 14. Each base station 12 mainly contains at least one sector (not shown), each of the sector contains an omnidirectional antenna or an antenna, is oriented in a specific radial direction from the base station 12. Alternatively, each sector can contain two antennas for receive diversity. Each base station 12 may preferably be configured to support multiple frequency bands. The intersection of a sector and the frequency range may be referred to as channel mdcr. Base station 12 may also be referred to as transceiver base station subsystems (PBS) 12. Alternatively, the term "base station" may be used in the art to identify a combination of ASC 14 and one or more PBS 12. PBS 12 may also be referred to as "cell sites 12. Alternatively, the mobile nodes may be called private sector this PBS 12. Mobile subscriber apparatuses 10 are usually cell phones, or phones PSS 10.

During normal operation of the cellular telephone system base station 12 receives the sets of signals a return line from the group of the mobile stations 10. Mobile stations 10 carry out phone calls or other forms of communication. Each feedback signal lines of communication adopted by this base station 12, is processed in it. The resulting data is transmitted in ASC 14. ASC 14 provide the resource allocation for the call and control functions of mobility, including the organization of agcih switching communication channels between the base stations 12. ASC 14 also route the received data in UKPC 16, which provides additional routing services for interfacing with the PSTN 18. Similarly, the PSTN 18 is associated with OCPS, and UCPS 16 associated with ASC 14, which, in turn, instruct the base stations 12 to transmit the sets of signals in a straight line in the direction of groups of mobile stations 10.

If the mobile station moves from the coverage area of the first base station in a system with a single carrier in the service area of the second base station in a system with a single carrier, the rules of IS-95. If the mobile station moves from the coverage area of one system with multiple carriers in the service area of another system with multiple carriers, it is possible to use different variants of the present invention for the Autonomous transmission SIPC with the mobile station.

Figure 2 illustrates the sequence of operations variant of the invention, in which the mobile station in a system with multiple carriers Autonomous forms SISK. At step 200 the mobile station enters a service area of several neighboring base stations. For clarity, we are going to discuss only one base station, although it is clear that all the neighboring base stations are similar to the base station randomly selected for discussion the Oia. At step 210 the mobile station continuously searches for and receiving signals of pilot channels on multiple carriers. At step 220 the mobile station determines the signal levels of the pilot channels according to the definitions of the signal level of the pilot channel. At step 230, the base station sends the mobile station a set of rules that contain conditions which must be complied with this mobile station during the formation of Autonomous SIPC. It should be noted that step 230 is performed by the base station repeatedly during the entire process described here, therefore, step 230 can be performed in this embodiment of the invention at any point in time. At step 240 the mobile station compares the signal level of the pilot channel conditions specified in the rule set that is passed to step 230. At step 250 the mobile station generates SIPC if the comparison at step 230 satisfies at least one of the conditions for the formation of SIPC. At step 260 the mobile station resumes the detection signals of pilot channels on multi-carrier and repeats the described method.

In one embodiment of the invention, the signal level of the pilot channel can be defined with regard to the ratio of the energy of the pilot channel on one element of the signal (Ec) to total adopted spectral density of noise and signals (Io), so that the mobile station is I will still be able to use the rules of standard IS-95. The signal level of the pilot channel for a system with multi-carrier 3 is defined as follows:

(1) PS1=10×log(Ec/Io of the primary pilot channel)

where the primary pilot channel (usually the one that has the highest power transfer) specifies the base station.

(2) PS2=10×log{[(Ec/Io of the pilot channel)11+(Ec/Io of the pilot channel)22+(Ec/Io of the pilot channel)33]/3},

where (Ec/Io of the pilot channel)i- Ec/Io of the pilot channel measured at the i-th carrier frequency, and Δi- the ratio of the transmission power of the pilot signal of channel i to the transmit power of the primary pilot channel for i=1, 2, and 3.

(3) PS3=10×log{max[(Ec/Io of the pilot channel)1, (Ec/Io of the pilot channel)2, (Ec/Io of the pilot channel)3]}.

(4) PS4=10×log{max[(Ec/Io of the pilot channel)11, (Ec/Io of the pilot channel)22, (Ec/Io of the pilot channel)33]}.

Although in the above definitions indicate the signal levels of the pilot channels in a system with multiple carriers 3, this variant of the invention can be used in systems with more or fewer carrier by manipulating the members of the Ec/Io signal, the pilot channel received from other carrier frequencies.

In equation (1) the signal level of the pilot channel is determined solely by the Ec/Io of the primary pilot channel. In equation (2) the signal level of the pilot channel is determined by the weighted sum of all three pilot channels. In equation (3) is the maximum of all three pilot channels. In equation (4) uses the pilot channel is adjusted for maximum power. The preferred method is the use of rules IS-95 signal level of the pilot channel defined by the equation (2). Another preferred method is the use of the rule IS-95 signal level of the pilot channel defined by the equation (1), so that the mobile station requires only one search pilot channel to the main channel. The following is the preferred approach is to use a combination of the definitions of the signal level of the pilot channel according to the specified rules of the group rules. For example, determining the signal strength of the pilot channel according to equation (3) can be used if the system implements a rule 1 or rule 2 of the standard IS-95A, and the determination of the signal level of the pilot channel according to equation (2) can be used if the system applies instead of rule 3. Using this combination of the definitions of the signal level of the pilot channel, the mobile station will report higher levels of signals of pilot channels of the set of neighbors more actively, and decreasing signal levels of the pilot channels in the active set more passively.

In another embodiment of the invention, the signal level of the pilot channel can be determined in accordance with the following equations:

(51) PS5 1=10×log[(EC/Io control channel)1],

(5-2) PS52=10×log[(Ec/Io control channel)2],

(5-1) S53=10×log[(EC/Io control channel)3],

where used individually Ec/Io of each pilot channel. In yet another variant of the invention determine the signal strength of the pilot channel according to the equations (5-1), (5-2) and (5-3) can be used in conjunction with the rules IS-95, the pilot channels on each carrier are subject comparisons, as prescribed in the rules IS-95. In another embodiment of the invention the levels PS51, PS52and PS53individual pilot channels are used in a new group of rules described below:

1. The signal levels of the pilot channels of the set of neighbors of pilot channels or set other stations satisfy the following conditions:

PS51>TADD,

PS52>TADD-[10×log(Δ2)], and

S53>TADD[10×log(Δ3)].

2. All signal levels (PS51, PS52and S53the pilot channels of the set of candidates exceeds the corresponding signal strength of any pilot channel active set by the value of TCOMP×0.5 dB, and SUPK this information has not been sent since then, as it was the last message about the direction of switching of the communication channels (SNP) or an extended message about the direction of switching of the communication channels (RSNP).

3. Expired in EMA timer reset switch communication channels pilot channel active set, i.e.

PS51<TDROP,

PS52<TDROP-[10×log(Δ2)], and

PS53<TDROP-[10×log(Δ3)],

at least for the time interval specified in TDROPand SIPC this information has not been sent since then, as it was the last SNP or RNP.

When in the above set of rules uses the pilot channel, defined as PS51, PS52and S53and satisfied at least one condition from this set, the mobile station autonomously transmits SIPC in the serving base station.

It should be noted that it is possible to modify the above rules using the signal strength of pilot channels from equations (5-1), (5-2) and (5-3), without limiting the scope of the invention. For example, rule 2 above, the rule set can be replaced by the following rule:

Alternative 2. Any of the signal levels of the pilot channel (PS51, PS52and S53the pilot channels of the set of candidates exceeds the appropriate level of any pilot channel active set by the value of TThe OMRS× 0.5 dB, and SUPK this information has not been sent since then, as it was the last SNP or RNP.

Also there could be different variants of the invention, in which the levels PS51, PS52and S53signal pilot channel are combined with the other defined the s signal strength of the pilot channel, such as PS1, PS2, PS3 and PS4. Can be implemented in a combination of these signal levels of the pilot channel, in which one condition of the rule set uses one definition of the signal level of the pilot channel, and the other determining the signal level of the pilot channel is used in connection with another condition.

The above-described variants of the embodiment of the invention intended to be implemented in the mobile station, which moves from one system multi carrier to another system with several carriers. However, these options can be modified to allow the mobile station to move from a system with multiple carriers in the system with one carrier or Vice versa.

In the embodiment where the mobile station moves from a system with multiple carriers in a single carrier system with one carrier uses one of the system channels with several carriers. Otherwise, there is a situation of hard switching of the communication channels. Under hard switching communication channels refers to the case when the mobile station moves between disjoint groups of base stations, ranges, different class, different frequency or different time frames. Search hard switching of the communication channels will not be discussed here in more detail. In the case when the two underlying the E. of the station are not simultaneously in the active set, the active set of pilot channels in multi-carrier is replaced with a new active set pilot channel on a single carrier. It should be noted that it is possible theoretically to perform soft switching of the communication channels between the base station 3X/1X (i.e. the base station using three bearing in a straight line and one bearing on the return line) and the base station 1X/1X (i.e. the base station using a single carrier in a straight line and one bearing on the return line), if you use the same encoding speed in a straight line, and the same RF channel and the structure of the radio signals on the reverse link.

One of the preferred variants of this type of switching communication channels is the use of signal pilot channel system with multiple carriers, which corresponds to the signal of the pilot channel is used by the system with a single carrier. If this channel is not the primary channel in a system with multiple carriers, the pilot channel associated with this channel, has a power level smaller by a factor of Δ. Therefore, it is necessary to exclude from consideration the factor Δbefore performing any comparison for TThe OMRSor TDROP.

In another embodiment uses equation (2) for determining the weighted sum of all the pilot-Kahn is fishing in a system with multiple carriers and this weighted sum is used in the rules according to IS-95.

Alternatively, the system can avoid switching communication channels between multiple base stations through a transition with multiple bearing one bearing inside the serving base station, and then switch communication channels from one carrier to another one carrier according to IS-95.

When the mobile station moves from a system with single-carrier system with multi-carrier system with one carrier uses one of several channels in a system with multiple carriers. Otherwise, there is a situation of hard switching of communication channels and begins to search hard switching of the communication channels. In the case where two base stations are simultaneously in the active set active set of pilot channels from the system with a single carrier is replaced with a new active set of pilot channels from the system with several carriers. It should be noted that it is possible theoretically to perform soft switching of the communication channels between the base station using a single carrier in a straight line and one bearing on the return line, and the base station using multiple bearing on a straight line and one bearing on the return line, if you use the same encoding speed in a straight line and the same RF channel and the structure of the radio signals on the reverse is the turn of the connection.

One preferred variant of this type of switching of the communication channels is the use of rules IS-95 using a pilot channel in a system with a single carrier. If this channel is not the primary channel in a system with multiple carriers, the pilot channel associated with this channel, has a power level smaller by a factor of Δ. Therefore, it is necessary to exclude from consideration the factor Δbefore performing any comparison for TThe OMRSor TDROP.

As noted above, another option is to use equation (1) or equation (2) to calculate the signal strength of pilot channels in a system with multiple carriers and using this result, according to the rules of IS-95.

Alternatively, the system can avoid a situation of transition from a system with single-carrier system with multi-carrier through the transition from one carrier to multiple bearing inside the serving base station and then switch communication channels with several carriers several carriers such as from one system 3 on another system 3.

After the mobile station has determined that it should send offline SIPC base station in the communication system, it is necessary to perform determination regarding the content of this SIPC. Not what which embodiments of the invention is preferred to pass the PS2 level signal, the pilot channel for each pilot channel, mentioned in SIPC. Accordingly, it will be also preferable to pass the levels PS1, PS3, PS4 signals the pilot channel and/or a group containing PS51, S52and S53for each pilot channel, referred to in SIPC. Therefore, the mobile station will be able to form SIPC containing information about the signal level of the pilot channel received from the definitions of the signal level of the pilot channel, which is not used in the comparison of the signal levels of the pilot channel with the threshold levels. If reported PS51, PS52and S53requires three times more space for the field level pilot channel in SIPC.

Another important field in the message SIPC field is PSH (psevdochumoy) phase of the pilot channel. PSH phase control channel is used to determine PSH of the shift, which is used to identify the pilot channel and the estimate of the delay on the path of propagation of the signal between the mobile station and the target base station. One approach is the message phase the earliest came multipath signal pilot channel, reported in SIPC from all three carriers. The second approach consists in message phase the earliest came multipath signal of the primary pilot channel. The third approach is to report the earliest phase came multipath signal is very strong making the CSOs pilot channel (with the highest Ec/Io). The fourth approach is the message phase the earliest came multipath signal, the pilot channel for each carrier frequency. In the fourth approach will require multiple fields phase PSH pilot channel for each PSH reported the pilot channel.

Figure 3 shows the mobile station 300 that is used in the manner illustrated in figure 2. The mobile station 300 measures the continuous or intermittent intervals the signal level of the pilot channels from the neighboring base stations. The signals of the pilot channels may be more than one carrier frequency. The signals received by the antenna 350 of the mobile station 300, fed through a duplexer 352, the receiver 354, amplifying, converting with decreasing frequency and filtering the received signals that are then fed to the demodulator 358 pilot channel search subsystem 355.

In addition, the received signals are fed into the demodulator 364A-364N signals traffic. These demodulators or subgroup separately demodulated signals received by the mobile station 300. The demodulated signals from the demodulator 364A-364N signals traffic is served in a multiplexer 366, which combines the demodulated data, providing, in turn, refined estimate of the transmitted data.

The mobile station 300 measures the signal strength of pilot channels. Control processor 362 provides the parameters I the statement in synchronism, set the base station to the search processor 356. In particular, the control processor 363 provides the parameters entering in synchronism to perform the method described with reference to figure 2. Control processor 362 stores in memory 372 parameters of the control channel signal including in this exemplary system mdcr values of the signal level of the pilot channel PN shifts and frequency. Control processor 362 then accesses memory 372 for search planning pilot channel is performed by the search subsystem 355. As a control processor 362 can use conventional microprocessor known type. In this exemplary embodiment, the communication system mdcr control processor 362 delivers the PSH of the shift in the search processor 356 in accordance with the signal of the next pilot channel, the search must be carried out. The search processor 356 generates a PN sequence that is used by the demodulator 358 signal, the pilot channel for demodulating the received signal. The demodulated signal of the pilot channel is fed into the battery 360 energy, which measures the energy of the demodulated pilot signal channel through the accumulation of energy within the specied time intervals and transmission of samples of such accumulated energy in the control processor 362.

In this exemplary embodiment, from which bretania control processor 363 performs digital filtering of the accumulated samples of energy according to the definitions of the signal level of the pilot signal, forming thereby the value of the signal level of the pilot channel. Then, the control processor compares the signal level of the pilot channel with threshold TADDand TDROP.

Control processor 362 transmits the IDs of the pilot channels and the corresponding measured values of levels in the generator 370 messages. Generator 370 messages generates the message signal level measurement pilot channel with this information. Message level measurement signal, the pilot channel is fed into the transmitter 368, which encodes, modulates, converts with increasing frequency and amplifies the message. After this message is transmitted via the duplexer 352 and the antenna 350.

Thus been described a method and apparatus for forming a message signal level measurement pilot channel. This description will enable any person to make or use the present invention. For specialists will be apparent, various modifications of the described variants, as described here, the General principles can be applied to create other options without resorting to creative activity. Therefore, the present invention is not limited to the described variants, and has a wide volume corresponding to the disclosed principles and significant new features.

1.
