Description

METHOD AND APPARATUS TO INTERRUPT A TRANSMISSION OF A MULTI-EMISSION SIGNAL FIELD OF THE INVENTION The present invention relates, in a general manner, to an apparatus and method of mobile communication and, more specifically, to a transmission of multi-station signals in a wireless network to service a plurality of communication devices. mobile BACKGD OF THE INVENTION Typically a wireless network is configured to transmit over a number of common and dedicated channels. The common channels carry information to a plurality of mobile devices either simultaneously, such as thh a broadcast or individually, or thh independent addressing means. Mobile devices can also be configured to receive a multi-broadcast or broadcast signal on a common channel, where the multi-broadcast or broadcast signal is a message signal generated by a central communication source, such as a computer server, and transmitted simultaneously to a plurality of mobile devices. If a multi-broadcast or broadcast service is required to retransmit the Multi-broadcast or broadcast information on the basis of an individual user or a subset of users, this results in a loss of the efficiency of the multi-broadcast or broadcast service. According to the standards of the third generation society project (3GPP), a Universal Mobile Telephone System Network (ÜMTS) allows the operation of four different states in connected mode, CELL_DCH, CELL_FACH, CELL_PCH and URA_PCH. In the CELL_FACH state, the mobile checks a common physical channel based on some predefined selection rules, identified by one or more channelization codes. The network can map multiple common data channels on the same common physical channel. The different common channels can be configured differently, so as to provide a different transmission quality, typically for different services, on the same common physical channel. The mobile device typically checks one of the common channels over a common physical channel assigned. When in the CELL_FACH state, a mobile device is generally available to receive information thh a common channel driven by its network, but must periodically suspend the reception of the signal over the common physical channel associated with the common channel. Those intervals where the reception of the common physical channel is suspended are usually called measuring occasions. During a measurement occasion, the communications device tunes its receiver to a different frequency for purposes such as the measurement of other physical channel frequencies commonly of the same or different system. When a measurement occasion occurs, the mobile device typically can not receive incoming information on the currently assigned common physical channel, due to lower limitations of receiving two physical channels of different frequency. Generally, a network seeks to uniformly distribute the measurement of measurement occasions within the coverage area. This helps the efficient use of common physical channels. A typical UT S network knows how to tune the measurement occasions for mobiles in a particular cell. Under the specification of the current 3GPP TS 25.331 UTMS, the network determines when those measurement occasions will occur and does not transmit data directed to a particular mobile during the time intervals when the mobile is on a measurement occasion. Since different mobile devices will lead measurement occasions at different times on the basis of their individual identities, the network will not be able to reliably transmit a multi-broadcast transmission in an efficient manner that can be fully received by all subscribed mobile devices. Also if a multi-broadcast signal is transmitted over a separate common physical channel, the conventional common data channel can be underutilized and neither can messages be delivered to the mobile device if the mobile device chooses to receive the multi-broadcast transmission instead of the transmission destined thereto over conventional common data channels. Thus, there is a potential conflict between when a mobile device can make a measurement occasion and the reliable reception of a multicast or broadcast signal. Because each mobile device can make its measurement occasion at different time intervals, or during different system charts, a multi-broadcast or broadcast signal can not be received by mobile devices that make a measurement occasion during a period when it is transmitted a multi-broadcast or broadcast. Also, if the length of the multicast or broadcast signal is greater than that of the system box, this increases the number of mobile devices that do not they can receive the multi-broadcast signal or full broadcast. In this way, there is a desire to assign measurement occasions of mobile stations within a coverage area in order to reduce their impact on the broadcast or broadcast service reliably and efficiently.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES The method and apparatus for interrupting a transmission of a multiemmission signal uses a common identifier for mobile devices within a coverage area that receives a particular multiemmission service. As used herein, the term "multi-emission" embraces the term "emission." The common identifier indicates the time intervals where the transmission of the multicast signal should be interrupted, so that mobile devices can make measurement occasions without losing portions of the multicast signal. In one situation, a network configures multiple common data channels on a common physical channel. A common channel is set aside for multi-broadcast transmissions, referred to as a common multi-demise channel. Other common channels referred to as conventional common data channels are used to transmit dedicated data, among other information, to a wireless mobile device. However, since both channels are plotted on the same common physical channel, at any time that the mobile device interrupts the reception of the conventional data channel for a measurement occasion, the mobile device will also stop receiving the multicast transmission that is being transmitted on the multi-broadcast channel. In this way a modality interrupts the transmission of a multi-broadcast signal on a common multi-broadcast channel, so that no information is lost when the mobile is making a measurement occasion. In another embodiment, the network further subdivides the time intervals where the ultiemision signal is interrupted. Sub-time slots are based on additional subgroups of mobile devices that receive multi-broadcast transmissions. In one embodiment, this additional sub-grouping may be based on: the identity of the individual multicast service in the event that multiple multi-transmission transmissions are simultaneously transmitted to different mobile cell devices; in a unique identifier of cell registration area or UTRAN; and / or any other identity that allows the network to subdivide the mobile devices into groups. A method and apparatus for interrupting a transmission of a multi-broadcast signal includes a common channel selector coupled to a receiver, so that the common channel selector receives information from the channel thereof. The method and apparatus further includes a repetition value calculator receiving information from the common channel selector measurement occasion to calculate a repetition factor of the transmission interruption time interval. A number comparator of the system box is coupled to the calculator of the repetition value of the common channel selector, where the comparator of the number of the system box determines whether a measurement occasion will be made based on the repetition factor, a common identifier and a range of transmission time of the largest common channel.

The method and apparatus further includes a generator of the measurement occasion coupled to the comparator of the system frame number, where if a measurement occasion is made, a signal of occasional measurement orders is provided to the generator of the measurement occasion and the generator of the measurement occasion generates a chance of measuring the channel. More specifically, Figure 1 illustrates a wireless mobile device 100 that includes a receiver 102 having an antenna 104, a common channel selector 106, a repetition value calculator 108, a comparator of the system frame number 110 and a measurement occasion generator 112. These functional blocks can represent executable program instructions, individual processors, application-specific integrated circuits, processors of digital signals, processors, fixed instructions or firmware, microcontrollers, state machines, or any other recognized operating component capable of execute program instructions where program instructions may be placed in a ROM, RAM, EEPROM, compact disc, digital versatile disk, optical medium, or any other volatile or non-volatile storage medium. Examples of a wireless mobile device 100 are: a radio, a cell phone, a smartphone, a personal digital assistant with a wireless transceiver, a personal computer with a wireless receiver, or any other suitable wireless device. Note that the receiver 110 will often be part of a transceiver in a communication device. In one embodiment, the receiver 102 receives a signal from the incoming common physical channel 114 via the antenna 104. The receiver 102 provides common channel information 116 to the common channel selector 106. As discussed above, the common channel information 116 includes information of emission, information of system parameters, transmission of multitude, or any other suitable information as recognized by someone who has experience in the technique. The common channel selector 106 performs several operations including, but not limited to, extracting the information from the measurement occasion 118 from the common channel information 116. The selector The common channel also operates to select one or more of the common channels on the common physical input channel. In one embodiment, the information of the measurement occasion 118 may be a cycle length coefficient of the common channel measurement occasion, commonly referred to as "k." The information of the measurement occasion 118 is provided to the calculator of the repetition value 108 so that the repetition value calculator 108 can calculate the one repetition factor 120. In one embodiment, the repetition factor 120 can be the length of the site of the measurement occasion that is determined by the calculations of two to the power of the measurement occasion information, k.The common channel selector 106 also determines from the common channel information 116 a transmission time slot of the largest common channel 122. The transmission filter interval of the common channel major 122 represents the longest transmission time interval of all common channels plotted on the common physical channel corresponding to whereby the mobile device 100 receives the transmission 114. In one embodiment, the transmission time slot of the longest common channel 122 is represented as the factor. Within the mobile device 100, the comparator of the system frame number 110 receives the repetition factor 120 of the repetition value calculator 108, the transmission time interval of the longest common channel 122 of the common channel selector 106 and a common identifier 124. In one embodiment, the common identifier 124 is a temporary identifier of the radio network. The common identifier 124 is provided to the mobile device 100 through the receiver 102, and the common identifier 124 is provided before providing the multicast service to the mobile device 100. The comparator of the frame number of the system 110 determines whether an occasion will be effected measurement. The comparator of the frame number of the system 110 calculates the timing of the measurement occasion using the repetition factor 120, the transmission time interval of the longest common channel 122 and the common identifier 124. The timing of the measurement occasion can be determined according to calculations of the known common channel measurement occasion using common ID 124 instead of a temporary ID of the cellular radio network, such as a C_RN I. On the basis of the determination of the comparator of the frame number of the system 110, if it is determined that the measurement occasion can be carried out, the comparator of the system frame number 110 generates a measurement occasion order signal 126, which is provided to the generator of the measurement occasion 112.

The comparator of the frame number of the system 110 can determine, on the basis of the common identifier, whether a measurement occasion should be effected by any of multiple multi-broadcast services or by a single multi-broadcast service. The measurement occasion generator 112 then generates a channel measurement occasion 128, according to the known channel measurement occasion procedures. Therefore, the mobile device 100 can interrupt the reception of a multi-broadcast signal during a time interval determined by the system box number comparator 110 to effect the channel measurement occasions 128. In addition, the device 100 can operate according to a corresponding network (not shown), so that the mobile device 100 does not lose any multi-broadcast data provided through a multi-broadcast channel because a channel 128 measurement occasion is made. Also, as discussed in more detail below, the mobile device 100 also determines, on the basis of comparison of the comparator of the system box number 110, whether the device mobile 100 can read data from the conventional common data channel during a time interval designated by a network to interrupt the transmission of data over the multi-broadcast channel. Figure 2 illustrates a graphical representation of a portion of a plurality of frames of the system 200 designated by a single frame 202 in relation to the transmission time interval 204. In the embodiment presented in Figure 2, the transmission time interval 204 It has a length of 4 times the frame 202. Although, as is known to a person skilled in the art, the ratio of the transmission time interval 204 to the frame 200 can be any suitable number as defined by a frame 202 according to the standard transmission timing, such as a 10 millisecond frame. Figure 3 illustrates the trace of multiple common channels 300, 302 and 304 to a single physical channel such as 306, such as a SCCPCH (Secondary Common Control Physical Channel) of a UMTS system. Common channels 300, 302 and 304 can be channels can be conventional common data channels, such as a FACH, for carrying non-multi-broadcast data or can be common multi-broadcast channels, such as a multi-broadcast FACH, for transporting multi-broadcast data . Therefore, with with respect to Figure 1, the receiver 102 can receive the physical channel as 306 and the selector of the common data channel 106 determines the longest common transmission time interval 122 of the three common channels 300, 302 and 304. As is recognized by an expert in the art, FIG. 3 illustrates a trace of three common channels of a common physical channel 306, although any suitable number of common channels may be plotted on it. Figure 4 generally illustrates a network 400 in communication with a plurality of cells 402, 404, 406 and 408. As understood by one skilled in the art, cells 402, 404, 406 and 408 designate a geographic area where the mobile device can perform wireless communications between corresponding base stations 410, 412, 414 and 416, 'respectively. In a typical embodiment, the network 400 communicates with the base stations 410, 412, 414 and 416 via a communication link 418, 420, 422 and 424, respectively. Those communication links 418, 420, 422 and 424 may be a communication link such as, but not limited to, a Ti connection, a wireless connection or any other suitable communication connection as recognized by one skilled in the art. The representative cell N 408 is shown with a higher level of detail that has a plurality of 430 mobile devices, 432, 434 and 436. Each of these mobile devices, in one embodiment, correlates with a mobile device 100 of Figure 1 to communicate with the base station 416. The network 400 can provide conventional common data channel data and multi-broadcast data through different common channels within a physical channel common to the mobile devices 430, 432, 434 and 436 within the designated cell 408. In coordination with the mobile device that interrupts the reception of a multi-broadcast signal, the Network 400 also performs the corresponding functionality for the interruption of the transmission of the multi-broadcast signal on the multi-broadcast channel. Network 400 functionality can be performed by one or more processors executing program instructions, application-specific integrated circuits, digital signal processors, microprocessors, physical instructions, microcontrollers, state machines, or any other recognized operating components capable of of executing program instructions where program instructions 100 may be placed in a ROM, RAM, EEPROM, compact disc, digital versatile disk, optical medium, or any other means of volatile or non-volatile storage. In one embodiment, the network 400 of Figure 4 performs the operations defined by the steps of the flow chart of Figure 5. The method for interrupting the transmission of a multi-broadcast signal 500 includes determining a common identifier for a plurality of mobile devices. on a common channel, step 502. A common identifier may be a temporary radio network ID specific to a multi-broadcast transmission which may be any other suitable identifier recognized by one skilled in the art. In one embodiment, the common identifier may be a single common identifier for a plurality of multi-broadcast services, such as different multi-broadcast transmissions or different services. While, in another embodiment, the common identifier may be restricted to a single multicast service so that if there is a plurality of multicast services, it may need a plurality of common identifiers. The next step, step 504 is to send the common identifier to the plurality of mobile devices. With respect to Figure 4, the common identifier may be transmitted from the network 400 to the base station 416 so that it is provided to the devices mobile 430, 432, 434 and 436 via wireless transmissions. In one embodiment, the common identifier can be provided to the mobile device through a system broadcast, where the system broadcast is any suitable broadcast that includes system information or other means to provide information to the mobile. In another embodiment, the common identifier can be provided to the mobile device through dedicated messages directed to the mobile device. The common identifier may be a temporary multi-broadcast radio network identifier, which is specific for multi-broadcast and temporary transmission during the duration of the multi-broadcast transmission. The next step is to transmit the multi-broadcast signal on a common channel, step 506. As discussed above, with respect to Figure 3, the common channel 300, 302 or 304 can be traced on a common physical channel 306 containing information from multiemisión in him. In one embodiment, the multi-broadcast signal may be transmitted on one of a plurality of common channels verified by multiple communication devices. After this, step 506 is the interruption of the transmission of the multicast signal during a time interval determined by the common identifier. In a similar way to the above discussion with respect to the comparator of the system frame number in Figure 1 which determines the time interval for a measurement occasion, the time interval can be determined using a larger common channel transmission time period, a repetition factor, k, and the common ID. After this, the method ends, step 510. In another embodiment, the method further includes the identification of a subset of mobile devices of multiple mobile devices, as illustrated in step 512 which represents another embodiment of the method of Figure 5. For example, using Figure 4 as reference, mobiles 430, 432, 434 and 436 can be further grouped into subgroups, such as mobile devices 430, 432 in group A and mobile devices 434, 436 in group B. Mobile devices can be grouped using a specific mobile identifier, which is recognized by a person skilled in the art is assigned to the mobile device when it has access to the state of the common channel. In one embodiment, the specific mobile identifier is a temporary identifier of the cellular radio network (C_RNTI). The method further includes selectively transmitting one or more signals from the conventional common data channel to the mobile device of a subgroup. specific during the designated time interval during an interruption of the multicast signal, as illustrated in step 514 which represents another embodiment of the method of Figure 5. In one embodiment, the common common data channel signal and the common multi-broadcast channel signal are plotted on a common physical channel, as illustrated in Figure 3. Whereas, in another embodiment, the common common data channel signal and the common multi-broadcast channel signal are plotted on different common physical channels. In one embodiment, the mobile specific identifier may be used to identify a particular mobile device within a coverage area. In the modality where the specific identifier is the mobile is a C_RNTI, the mobile-specific identifier can identify devices within a particular cell. In this mode, the specific identifier of the mobile is assigned when the mobile enters the state of the common channel, and is associated with a particular cell. In addition, the mobile-specific identifier can identify a particular mobile device in a radio coverage area, such as a UTRAN registration area. FIG. 6 illustrates a flow diagram of the steps for a method for interrupting a reception of a multi-broadcast signal in a wireless communication device. The method starts in step 600, obtaining a common identifier, step 602. As discussed above with respect to FIG. 1, the common identifier can be a temporary identifier provided by the network. In one embodiment, the common identifier can be obtained through a broadcast message. In another embodiment, the common identifier can be obtained through a message dedicated to directing a wireless communication device. The next step 604, receives a multi-broadcast signal. The multi-broadcast signal may be provided over the common multi-broadcast channel, where the multi-broadcast signal may include multi-broadcast broadcast information. Therefore, the next step is interrupted in the reception of the multicast signal during a first time interval based on the common identifier, step 606. Therefore, the method is completed, step 608. As discussed above with with respect to FIG. 1, the comparator of the system box number 110 determines the timing and the measurement occasion copper the base of the longest common channel transmission time interval 122, the repetition factor 120 and the common ID 124. When the occasion of measurement of the channel may occur, the reception of the multicast signal is interrupted so that the occasion of measurement of the channel can be effected. It is also noted that the term interruption here may further include simply not receiving information about a common multi-broadcast channel in the event that a multi-broadcast signal is not currently being transmitted. In addition, the time interval can be determined by the repetition factor assigned to; wireless communication device where the repetition factor is determined based on the information of the common channel. In one modality, the F1G method. 6 further includes making a measurement occasion during a time interval. Because the reception of the multicast signal has been interrupted, the mobile device can make the appropriate measurement occasion during the time interval without any loss of data. Although, as discussed in more detail below, if there is a timing difference between the period of the multicam frame and the period of the conventional common channel frame, the mobile device may receive a conventional channel transmission during a portion of the interval of weather.

In another embodiment of the steps of FIG. 6 the method for interrupting a reception of a multicast signal may also include obtaining a specific mobile identifier. As discussed above with respect to FIG. 5 the mobile specific identifier can be a C_RNTI. After which, the method includes interrupting the reception of a signal from the conventional common data channel during a second time interval based on the mobile-specific identifier -0. Similar to the interruption of the multicast transmission, the conventional common data signal may be interrupted so that a measurement occasion may occur. Although, as discussed in more detail below, due to 5 differences in the first time interval and the second time interval the mobile device can receive a conventional common data signal during a portion of the first time interval excluding the time of the second time interval. 0 FIG. 7 illustrates another embodiment of a method for interrupting the transmission of a multicast signal. The method begins at step 700 by receiving the channel configuration of a network, step 702. For example, as illustrated with respect to FIG. 5 4, network 400 provides configuration information of the channel through the connection 424 to the base station 416. The next step, step 704 is to identify a common channel of a second common physical channel selected with a longer transmission time interval. Similar to the functions performed by the mobile device 100, the longest common channel transmission time interval 122 is determined by the common channel selector 106. The next step, step 706, is to calculate a repetition value using the information of the measurement occasion acquired from the network, where in a manner similar to the modality discussed with respect to FIG. 1, the information of the measurement occasion 118 can be selected from the common channel selector 106. The next step is to use a temporary ID of the assigned radio network, the repetition value and the transmission time interval, to make a determination whether a system box number corresponds to the measurement occasion, step 708. Therefore, step 710, the decision is made as to whether a measurement occasion can occur with respect to a system box number, step 710. If a measurement occasion can occur, the next step is to make a channel measurement occasion, step 712. In the event that a measurement occasion can not occur, the method proceeds to step 714 which includes reading the selected common channel. In one embodiment, the common channel includes the conventional data channel, which does not carry data not belonging to a multiemmission and may also include the multi-broadcast channel that includes multi-broadcast data. The next step, step 716 is a determination of whether the transmission time interval ended. If the transmission time interval did not end, the method returns again to step 714 to read the selected common channel. If the transmission time interval ended the method proceeds to step 708. Therefore, the mobile device uses the ID of the assigned radio network and makes another determination as to whether the frame number of the system csponds to a measurement occasion. After which, the method repeats the entire decision step 710 until the measurement occasion can be performed, step 712, and after that the method concludes, step 718. In another embodiment, the mobile uses repetition factor and the number of the current system frame and the largest transmission time interval, to determine the start of the next transmission interruption time interval. FIG. 8 illustrates a graphic representation of a system box number 800 of several frames of system. In another modality, a timing sequence is composed of 4096 table numbered 0-4095. With reference to FIG: 8, FIG. 9 illustrates a common channel containing user data in multiple system boxes 900. System tables 900 show conventional common data channel data frame units having a range of a system box. Illustrated better in the system boxes 900 of FIG. 9 are the identifiers for four prepared subgroups of mobile devices, specifically subgroup A 902, subgroup B 904, subgroup C 906 and subgroup D 908. As recognized by one skilled in the art, there may be a number of several subgroups in the The selection of subgroups 902, 904, 906 and 908 shown are for exemplary purposes and are not designated as limiting here. FIG: 10 illustrates a graphical representation of multi-broadcast data frames 1000 with a multi-broadcast data time slot 1002, spanning four frames of the system, thus incorporating a range in which all subgroups AD 902, 904, 906 and 908, respectively, are associated. As discussed above, FIG. 10 illustrates an exemplary embodiment of a multi-broadcast channel containing data multicast with a single time interval for the interruption of transmission, where the time interval occurs over a four-frame interval. As recognized by one skilled in the art, any other suitable time intervals for the multi-broadcast data may be used. FIG. 11 illustrates a graphical representation of a common data channel with a single subgroup, group A. The method and apparatus for interrupting the transmission of a multi-broadcast signal provides a mobile device for setting its measurement occasion according to the intervals of transmission interruption time for the multi-broadcast channel because the multi-broadcast channel has, in this exemplary embodiment, a timing interval that is four times as large. Although, as represented in FIG. 11, when a mobile device in a group A makes a measurement occasion in which it occurs during a single frame interval 1100, the time slot 1102 is not occupied. Therefore, the mobile device makes the occasion of measurement during the interval A 1100 and reads any conventional common data channels available during the 1102 interval. Therefore, the transmit bandwidth and system availability are not wasted for three tables of the 1102 system, in which the multi-broadcast channel is interrupted by measurement occasions and, where group A makes its measurement occasion during frame 1100. FIG. 12 illustrates another embodiment where mobile devices can be grouped into two subgroups, subgroup A 1200 and subgroup B 1202. Similarly to the operations illustrated in FIG. 11, group A coordinates its measurement occasions with respect to tables 1002 of FIG. 10 but reads the communication data on conventional common data channels available during the designated time intervals 1202 and 1204, similarly the interval 1102 of FIG. 11. In addition, the mobile device in group B 1202 has a multicam time slot 1002 of the FIG. 10 but only needs to take the measurement occasion during the designated time table 1202. Therefore, the mobile devices in group B 1202 can read data from conventional common data channels available during the designated time, 1200 and 1204. Therefore, when multiple mobile devices with different subgroups are associated, the active reading that the conventional common data channels during intervals when the multi-broadcast channel has been interrupted allows further use. efficient bandwidth of the common conventional data channel available. It should be understood that there are implementations of other variations and modifications of the invention in several aspects, and those skilled in the art can be readily apparent so that the invention is not limited to the specific embodiments described herein. For example, the number of subgroups for mobile devices can be any number that allows efficient utilization and allocation of resources to maintain efficient utilization of bandwidth over a common physical channel. Therefore, any and all modifications, variations and equivalents that fall within the scope of the underlying basic principles described and claimed herein are contemplated and covered by the present invention.
