Description

Technical field

The present invention relates to battery-powered mobile stations and, more specifically, is aimed at achieving a balance between saving battery life with other factors affecting the performance of a mobile station

State of the art

Mobile communications has evolved from first-generation analogue mobile radio systems to second-generation digital systems such as the European Global System for Mobile Communications (GSM). The current development of the third generation mobile radio communication systems is defined as the Universal Mobile Telephony System (UMTS). Simply put, UMTS means “communication with any person, wherever he is”, and communication includes providing information using various types of transmission media, i.e. multimedia communication. The purpose of the UMTS services is to combine both stationary and mobile services to form a continuous “end-to-end” service for the user.

In view of the widespread success of the existing GSM platform, i.e. global “GSM fingerprint”, as well as the possibility of modernization and modularity inherent in the GSM platform, there is a powerful incentive to base UMTS on a “developed” GSM platform. Accordingly, the present invention is described in the context of a UMTS based on an advanced GSM platform and using GSM terminology. Of course, the principles of the present invention are not limited to UMTS, terminology and the GSM platform or any particular mobile communication network and can be implemented using other appropriate network platforms and configurations.

Modern mobile / cellular telecommunication networks are typically designed to connect and operate with public switched telephone networks (PSTN) and Digital Integrated Services Networks (CSCS). Both of these types of networks are circuit-switched, not packet-switched, and handle relatively narrowband traffic. However, packet-switched networks, such as the Internet, are very much in demand and handle much more broadband traffic than circuit-switched networks. Although wired communication terminals, such as personal computers, are capable of using a wider bandwidth of a packet-switched network, wireless mobile radio terminals have a significant drawback due to the limited bandwidth of the radio interface that separates the mobile terminals from packet-switched networks.

Thus, there is a need for a radio access system that provides wireless access at very high data rates and supports carrier channel services that are not actually achievable in first and second generation mobile communication systems. This need is best met in a Code Division Division Multiple Access (W-CDMA) broadband access radio network.

To facilitate understanding of the invention, at first, the UMTS system 10 is briefly described with reference to FIG. A representative, connection-oriented, external core network, shown as cloud 12, may be, for example, a public switched telephone network (PSTN) and / or a digital integrated services network (CSN). A representative, connection-oriented, external core network, shown as cloud 14, may be, for example, the Internet. Both networks 12 and 14 are associated with respective nodes 16 of the services of the core network (BS). The PSTN / DSCCH-type circuit switched network 12 is connected to a connection-oriented service node, such as a circuit-switched service node 18, which in the case of a GSM platform includes a mobile station switching center (MSC) 23 and a corresponding “visitors” location register ( RMB) 24. Also in the existing GSM platform, the circuit switched services node 18 is connected to a base station system (SBS) 26, which in turn is connected to a radio base station (BSS) 28 having a corresponding geographical cell region 34.

A connectionless service node is a packet switched service node 20 configured to provide packet switched type services. In the GSM platform, such a node corresponds to one or more nodes of the basic packet radio communication services (CSDS), such as SGSN, GGSN, etc. Each of the core networks 18 and 20 is also connected to the source location register (ROM) 22, in which the identification data of mobile stations, subscription data of services and information on mobility / location are stored. The nodes 18, 20 of the core network services are also connected to the radio access network (SDR) of the UMTS system (SDR-UMTS) 30, which includes one or more network radio communication controllers (TFRs) 32 connected to one or more base stations 28, each base station having a corresponding geographical area 34 cells. The radio access network 30 provides services towards and from the mobile station 36 via the radio interface to the core network services nodes 18, 20, and core networks need not request specific radio resources to provide these services. SDR-UMTS 30 “maps” the radio access channels to the physical radio channels - this function is mainly controlled by the network radio controllers 32. In the W-CDMA system, individual radio channels are allocated using spreading codes. As mentioned above, W-CDMA provides a wide bandwidth for multimedia services and other needs with high transmission speeds. In addition, it also provides reliability characteristics, such as diversity handover and multi-tap receivers, to ensure high quality communications.

When the mobile station is idle, i.e. does not participate in connection with SDR-UMTS 30, core networks should be able to determine the location and communicate with the mobile station. Mobile stations should also be able to initiate communications with core networks. Typically, common channels are used: one for the downstream direction from the base station to the mobile station (paging channel), and the other for the upstream direction from the mobile station to the base station (random access channel). Periodically, the mobile station registers or otherwise reports its presence to the base station of the specific cell in which it is currently located.

If in the nodes of the core network services it is not known in which particular cell the mobile station is currently located, then in the nodes of the core network services, the generic location of the mobile station is typically known, i.e. A group of cells, typically referred to as a location area. Therefore, when a call is to be routed to the mobile station from the core network, a paging procedure is performed in which a paging message is transmitted to the mobile station via a downlink paging channel requesting the connection of the mobile station with the radio access network 30 via the cell in which it located at the current time.

In order for the mobile station to receive paging messages, it must go into an active state, i.e. power must be supplied to it, and it must monitor, for the appropriate time, a particular control channel through which a particular paging message is transmitted. If a mobile radio communication device continuously consumes power and constantly monitors the paging channel, then it is highly likely that it will detect and accurately receive the paging call. However, mobile stations typically operate with battery power, and batteries have a limited life between recharging. Continuous monitoring of the paging channel, therefore, significantly reduces the battery life.

Accordingly, it is desirable to eliminate or otherwise minimize battery consumption, where practicable. The basic idea is to put the mobile station in low power mode or in “inactive” mode in order to save battery power if the mobile station does not need to perform any necessary functions. To ensure reliable reception of the necessary messages, the mobile station is periodically activated, switching from an inactive state to a power mode with a high power level so that it can receive messages, such as search calls, or transmit periodic updated data about its location via a common channel. The main problem of optimizing the inactive mode is to achieve a compromise between a long stay in the inactive state, which saves the power supply of the mobile station’s battery, and a shorter inactive mode, which provides higher characteristics, such as reducing call setup time or reducing data transmission delays in the downlink direction communication to the mobile station.

One of the methods for solving this optimization problem is to determine a constant period of inactive mode when all mobile stations are in a general compromise between saving battery life and transmission delays. Although this approach is attractive due to the relative ease of implementation and management, it does not take into account, among other factors, such as user preferences, priorities, and communication service requirements. It would be desirable to provide users with the ability to change the period of inactive mode in order to take into account such preferences, priorities and / or requirements of services. Moreover, in situations where there is low activity of mobile stations and when the location of mobile stations is known only in general terms, and not at the level of individual cells, it will be required that the fixed delay be relatively large, which requires a relatively long fixed inactive cycle. However, such a long period may not be suitable for other services requiring shorter delays. As a result, a fixed period of inactive state would require the installation of a short cycle of inactive state to satisfy the requirements of the highest activity mode and / or services that allow minimal delays. Thus, even if the mobile station must have a high level of activity or use the type of service with a low delay only for a short time, it should still be constantly activated with a high frequency. This high activation frequency leads to excessive consumption of the limited power of the battery.

The objective of the invention is to provide a mobile station inactive mode with power saving, and this mode should be changed taking into account specific factors or circumstances.

The objective of the invention is the creation of a variable mode of inactive state, in which the mobile station initiates a change in the variable mode of inactive state.

In addition, an object of the invention is to provide an alternating inactive state mode that takes into account various levels of activity of a mobile station.

Another objective of the invention is the creation of an alternating inactive state mode, which takes into account the priorities and preferences of the mobile station operator.

It is also an object of the invention to provide an alternating inactive state mode that takes into account various mobile station services and the time constraints associated with them.

Another objective of the invention is the coordination of variable modes of an inactive state when communicating with mobile stations with many core networks.

The present invention solves these problems and achieves these and other results by creating a mobile station operation method in which the inactive cycle of a mobile station can optimally vary depending on one or more conditions associated with the operation of the mobile station. Based on one or more of these conditions, the value of the variable activation parameter is determined, which is used to establish the times when the mobile station automatically leaves the low power consumption mode and enters the high power consumption mode, for example, to listen to a search call. A variable activation parameter of the mobile station is provided for the radio access network and for the core networks to ensure coordination of communication and services with the mobile station.

If there is a change in one or more conditions that relate to the operation of the mobile station, the value of the variable activation parameter may change in response to such a change. For example, a mobile station may operate at multiple levels of activity, and a detected change may include operating at a different level of activity from among multiple levels of activity. Different levels of activity have corresponding varying lengths of time required to set up a call or transmit downlink data. The detected change may also include a change in operating conditions initiated by the mobile station during the time that the mobile station is at one of these activity levels.

If the condition is the current level of activity of the mobile station, then the activation variable is changed so as to increase the frequency with which the mobile station is activated, respectively, a higher level of activity. For a lower level of activity, the activation variable may be varied so as to reduce the frequency with which the mobile station is activated. If the condition is a service that is currently being requested or whose subscriber is a mobile station, then the activation variable is changed to increase the frequency with which the mobile station is activated if the current service requires a low delay. If the service allows a high delay, then the activation variable may be changed so as to reduce the frequency with which the mobile station is activated. If the service includes the maximum delay parameter, the value of the variable activation parameter is changed so as to reduce the frequency with which the mobile station activates without exceeding the specified maximum delay parameter.

The present invention also allows the user to set the priority of battery saving or low latency, and, as a result of such a user priority, the activation variable can be changed accordingly. Moreover, the value of the variable activation parameter may also vary depending on the type of power source from which the mobile station is currently being powered. For example, a power supply with a shorter life span assumes a longer inactive cycle; a longer-life power supply requires a shorter inactive cycle.

In a preferred embodiment of the present invention, the activation parameter is calculated in accordance with the following relation: S = 2 ⁿ , where S is the duration of the alternating inactive state cycle, measured, for example, as an integer number of communication channel frames during which the mobile station is in low power mode power, and n is a variable integer. Assume that the base station and the mobile station communicate using a communication channel that is divided into a repeating sequence of M frames. The number of frames M in the sequence is preferably equal to the integer power of 2. The specific number W of activation frames when the mobile station enters high power mode can be determined in accordance with the following relation: W = (kS) moduloM, where k is an integer.

The approach using the variable inactive state according to the present invention also provides significant flexibility and optimization in communication networks, such as UMTS, shown in figure 1. For each of the core networks, the mobile station may have a corresponding inactive state variable. As a result, the time interval when a mobile station transitions from an idle mode with a low power supply to an idle mode with a higher power supply can vary based on current operating conditions and communication between the mobile station and core networks. The present invention also provides a method for coordinating and synchronizing activation time periods for a plurality of core networks having various inactive state variables of mobile stations.

Although the present invention does not exclude the fact that there is a compromise between saving battery power and quality of service and transmission delay, the possibilities of the inactive alternating state mode corresponding to the present invention make it possible to optimize this compromise in accordance with the individual goals and / or conditions of a particular user / mobile station.

Detailed Description of Drawings

In the following description, for purposes of explanation, but not limitation, specific details are presented, such as specific embodiments, data streams, examples of signaling implementations, interfaces, methods, etc., in order to explain the invention in detail. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments that differ from the specific embodiments given. For example, the present invention is described in the context of a non-limiting embodiment of the UMTS system 10 shown in FIG. 1 and described above. Thus, although the present invention has been described in the context of an exemplary cellular telephone network using GSM and UMTS terminology, those skilled in the art will understand that the present invention can be implemented in any cellular telephone system. In other cases, detailed descriptions of well-known signaling methods, interfaces, devices, and methods are omitted so as not to clutter up the description of the present invention with unnecessary details.

There is a relationship and relationship between the inactive state variable of the mobile station according to the present invention and the coordination of the location of the mobile station, including procedures for updating location data and paging. Such location updating procedures allow networks to track the location of mobile stations more or less accurately in order to be able to determine the location of a mobile station in the event of an incoming call. Location registration is also used to formulate the profile of the mobile station’s services in the area of its location and to enable the rapid provision of network services, for example, the function of registering the location of “visitors” in the GSM system. The paging process includes sending paging messages in all cells where the mobile station may be located. Therefore, if the cost of determining the location is high, based on the accuracy of determining the location of the user, then the cost of the search call will be low (since the message search call will be transmitted only within a small area), and the call setup will ultimately be much faster. On the other hand, if the cost of locating the location is low and the location information of the user is the most general or “blurred,” then the cost of the paging call will be high since the paging message will need to be transmitted over a wide area. Currently, the location method, the most widely used in first and second generation cellular systems, uses location areas (OM), as shown in FIG. Each location area includes multiple base station cells. Location areas allow you to track mobile stations, and the location of the mobile station is considered “known” if the system knows in which location area the mobile station is located.

Due to the various services provided at the UMTS and the significant demand for limited channel resources, the UMTS 10 uses various types of channel resources. Some examples are shown in figure 3. Some services, such as voice services, require a dedicated channel resource, i.e. dedicated channel. Other services that allow variable latency and throughput can use a more efficient common channel that is shared by many users. The base station thus transmits various service and identification information via the broadcast control channel (CCU); and typically, one or more paging channels (CPV1 ... CPVN) are used to transmit paging messages to mobile stations in a cell area of a base station. In addition, a common random access channel (CSD) is used by mobile stations in a cell of a base station to request services and transmit short data packets. The direct access channel (PCA) is a common channel that is used by a base station to transmit data to multiple mobile stations. SDR-UMTS 30 schedules time intervals for transmitting PKD for various mobile stations.

A more efficient use of resources can be achieved by allocating resources depending on the amount of transmitted data, for example, depending on the current level of activity of the mobile station. Each different level of activity has a corresponding location coordination situation. The following is an example of splitting into possible activity levels:

- The activity level A1 corresponds to a dedicated channel, which is typically used in the case of very high levels of activity or in the case of services that do not allow delays such as a voice service. SDR-UMTS 30 controls the installation of a dedicated data channel. The location of the mobile station is obviously known in this situation.

- A2 activity level corresponds to a common channel shared by many mobile stations, for which moderate to moderately high activity levels are typical. Examples of common data channels are a random access channel and a direct access channel, as shown in FIG. The location of the mobile station is known in SDR-UMTS 30 accurate to a specific cell, and SDR-UMTS 30 processes such a connection.

- The activity level A3 corresponds to the activity of the paging channel, which is used when the location of the mobile station is known in the SDR-UMTS with accuracy to the registration area of the SDR-UMTS (OR-USDR), i.e. cell groups, not at the individual cell level. Typically, paging channels have low activity.

- Activity level A4 corresponds to the activity of the paging channel controlled by one of the service nodes of the core network, because SDR-UMTS (USDR) 30 does not have information about the location of the mobile station in the idle state (inactive state), i.e. there is no current “connection” between the mobile station and the USRD 30. The activity level A4 corresponds to a very low activity when the location of the mobile station is known to within a large group of cells corresponding, for example, to the OR-URDD, i.e. known only at the level of core networks.

If there is a connection, both an uplink and a downlink, between the mobile station and the network, then the location of the mobile station is known and processed by the network. On the other hand, if there is no connection between the PDMA and the mobile station, then the location of the mobile station is known only in general, at the level of the core network.

It is rather inefficient and inconvenient to have one fixed inactive state mode that is optimally adapted to various activity levels of a mobile station, such as activity levels A1-A4. For example, it is not necessary to have a short delay period corresponding to a short activation cycle, which may be suitable for moderately high activity at the A2 level if the mobile station is in the idle state at the A4 activity level. In such a situation, frequent activations with high power to control the paging channel lead to wasteful use of the battery power of the mobile station.

The present invention rejects the inflexible approach using a fixed inactive state cycle and instead provides for an inactive state variable cycle that can be adjusted to best suit the current needs and operating conditions of the mobile station / user. There are many different ways to determine the variable cycle of an inactive state. Therefore, the method below is just a possible example. The variable inactive state cycle S can be defined as follows: S = 2 ⁿ , where n is the inactive state mode parameter, the value of which can be changed as necessary to change the inactive state mode cycle S. Typically, paging channels are divided into a series of frames, each of the frames having a frame number. The frame numbering scheme is performed “modulo”, which means that after reaching the last frame number, frame numbering is resumed from the beginning. Figure 4 shows an example of a paging channel and broadcast, having numbered frames 0, 1, 2, ..., M-1, where M is the number of frames in the repetition cycle. In this exemplary embodiment, the inactive variable mode parameter n is an integer from 0 to 2logM. The value of M should be selected taking into account the largest possible cycle of the inactive state mode and is preferably equal to the power of 2.

During the inactive mode cycle S, the mobile station enters a low power operation mode to save power of the power battery. At the end of the inactive cycle, the mobile station activates and enters a higher power mode to perform an operation such as paging control in the paging channel, before returning to the inactive state.

The mobile station may need information about which radio frequency should be monitored if several frequencies are used in the paging channel, which paging channel from the plurality of paging channels in the cell should be controlled, which frame should be monitored, and if the frames are divided into time intervals , then in what time interval should control the search call. One of the ways to select the frequency (if necessary), the identification data of the paging channel (if necessary), the frame number (F), the frame time interval (if necessary) is to use a selection algorithm based on the mobile identifier in the mobile station and in the UDR stations, such as International Mobile Subscriber Identity (MIMA). In any case, if the absolute frame number F is determined, then the frame numbers when the mobile station will be activated in accordance with the time moments of the probable receipt of the paging call are determined in accordance with the following relation: W = (F + kS) moduloМ, where k is an integer number. Figure 4 is an illustration of this ratio, which shows the activation frames W as F, F + S, F + 2S, ..., F + kS. By changing the variable n, the inactive state mode cycle of the mobile station is changed, as a result of which the W number of the frame in which the mobile station is activated, for example, to monitor a particular paging channel, also changes.

Knowing the MIMA of the mobile station and the current value of n, the mobile station, the UDR and the nodes 18, 20 of the core network services can easily determine when and where the search call for the mobile station will be transmitted from one (or more) base stations to the UDR 30. Network program ( block 50) provides exemplary procedures performed by all base stations in a location area where it is desired to send a paging call to the mobile station to the PDRC 30 or core network. The UDRF receives a command from the core network services node to send a paging call to the mobile station, and also receives a paging message, the MIMA of the mobile station and the value of the n inactive variable parameter (block 52). The particular paging channel, frame number F, and frame time interval (optional) are determined using the MIMA mobile station (block 54). Using the parameter n of the variable inactive state, the DRR then determines the cycle S of the variable inactive state of the mobile station, i.e. S = 2 ⁿ , and activation frames W using S and a specific paging frame F, for example W = (F + kS) moduloM (block 56). One or more base stations then transmit a paging message on the selected paging channel and in a dedicated time interval for each frame number W (block 58).

The base station (s) may retransmit the paging message a predetermined number of times to reduce the likelihood that the mobile station will miss the paging message due to a change in radio conditions or cell. A response to a paging call from a called mobile station is detected by a core network making a paging call, or possibly using a network radio controller (TFM). If the core network does not accept the answer to the search call, it can repeat the search call procedure one or more times. After that, if there is still no answer to the search call, the mobile station is considered as “disconnected” (not reachable).

Typically, transitions between different levels of activity, such as A1-A4, described above, are performed to optimize the use of radio resources and, accordingly, are initiated from and controlled by the SDRD 30. On the other hand, setting and changing a period of an alternating inactive state for a mobile station is determined by the mobile station / user and is based on factors such as optimization of the battery’s resource, desired performance, etc.

There are a number of ways to link variable cycles of an inactive state mode with different levels of activity. For example, a mobile station may use a default idle mode loop for all activity levels, but the mobile station has the ability to change the idle mode loop. Alternatively, various default inactive mode cycles can be stored both in the mobile station and in the PDLR 30 for each activity level. In this case, if the mobile station changes the activity levels, the inactive mode cycle changes automatically. In addition, the mobile station may vary the inactive mode cycle within each activity level. Thus, even if the cycle of the inactive state mode can be determined for each activity level, for example, in the form of a default value, the mobile station can change the cycle of the inactive state mode at a given activity level.

Consider a situation where a mobile station enters a new cell (block 60), with the following example procedures described using the flowchart in FIG. 6. The mobile station reads the broadcast channel (or other common channel) transmitted by the base station in a new cell (block 62). From the information provided in the broadcast (or other common) channel, the mobile station determines the corresponding paging channel (CPV), the frame number of the paging channel (F), and (optionally) the time interval of the paging channel using its MIMA (block 64). At a block 66, a decision is made as to whether the new cell belongs to a group of cells / location area where the mobile station is already registered. If not, then the mobile station registers in a new group of cells in USDR 30 and / or one of the core networks (block 68). Based on the current level of activity (for example, on activity levels A2-A4), the mobile station can determine the value of parameter n corresponding to its inactive state mode for a given activity level (block 70).

Of course, if a dedicated channel has already been established between the mobile station and the UDRN 30 (for example, activity level A1), the mobile station will not go into an idle state. As mentioned above, at activity level A2, when there is a connection between the mobile station and the UDRN 30, the mobile station registers in one cell and communicates on a common channel. Therefore, the USDR 30 does not need to send a paging call to the mobile station since the current cell is known. Data for this mobile station is transmitted over the common channel during the activation frames (W) calculated for the mobile station in accordance with the formula S = 2 ⁿ for the alternating inactive mode cycle (block 72) and the formula W = (F + kS) moduloM for the activation frame (block 74) using the corresponding activation parameter n (A2) inactive mode.

At activity level A3, when there is a connection between the mobile station and the UDDR and the mobile station is registered in the location area, the corresponding activity parameter n (A3) of the idle mode is used to determine S and W. Similarly, n (A2), n (A3) can also change at the initiative of the mobile station at any given time. For example, the inactive mode parameter may be increased if the user has priority in saving battery life. Similar procedures are also used for activity state A4.

As in the above example, the idle state parameter n may differ depending on the current activity level of the mobile station. In addition, there may be other procedures used to determine the current activity of the mobile station independently and / or in conjunction with a more formalized structure of the activity level, for example, activity levels A1-A4. In fact, many other factors can also be used to determine the corresponding inactive mode parameter, which optimizes the conditions for the current situation.

The inactive mode parameter may be changed based on the service that is being requested at the current time or which is subscribed by the mobile station. For services requiring less delay, it may be necessary to reduce the value of the variable idle mode parameter. Conversely, for a current service that allows higher delays, the inactive mode cycle parameter can be increased to reduce the frequency with which the mobile station is activated, thereby saving battery power. Of course, if the service has a maximum delay parameter, the value of the variable parameter of the activation mode cycle should not increase to such an extent that the resulting cycle exceeds the maximum delay parameter.

In addition, there may be specific data inputs directly by the user of the mobile station, reflecting the priority of saving battery life or providing shorter delays. If the user considers the saving of the battery power as a priority, the variable parameter of the activation cycle can be increased to reduce the frequency with which the mobile station is activated. Conversely, if shorter delays and faster response are desired for the user, the inactive cycle variable parameter can be reduced to increase the frequency at which the mobile station activates, which ultimately leads to shorter call setup times.

Another variable may be the type of power source of the mobile station. If the mobile station has a battery pack, the variable activation cycle parameter can be increased to save battery life. On the other hand, if the mobile station is temporarily receiving power from an electrical outlet, then the user can set a reduced alternating activation cycle, since saving power supply in this case is not fundamentally important. Different types of batteries, some of which have a shorter service life and others have a longer service life, provide different options for selecting different activation cycle parameters.

7 is a block diagram of a mobile station 36. A mobile station contains transceiver circuits 92 and other circuits (not shown) for performing typical functions of a mobile station. According to a possible embodiment of the present invention, the mobile station may also comprise a data activity detector 90, which determines the current activity level of the mobile station. For example, the data activity detector 90 may determine the average packet arrival time, measured over a given time interval. Data on the level of activity of data transmission are provided to the inactive cycle controller 96, which determines the value of the variable inactive state parameter n. For example, the inactive cycle controller 96 may select n based on a comparison of the current determined activity value with one or more thresholds. For higher levels of activity, the parameter n of the inactive state mode will have a lower value and vice versa. Activity data can also be determined based on the time since the last data transfer in comparison with the load. If this time exceeds a specific threshold, then the inactive mode parameter can be increased.

The mobile station 36 also includes a human-machine interface 94, which allows the user of the mobile station to enter the desired priorities with regard to saving battery life or a short delay time. These priority data inputs go to the inactive cycle controller 96 and to the communication services controller 100. The inactive state loop controller 96 then selects a higher value of the inactive state variable parameter n if the battery power saving is a higher priority, or a lower value if a shorter settling time delay is a priority. A power type detector 102 supplying the mobile station 36 provides data input to the inactive state controller 96, which indicate the currently used type of power supply of the mobile station. The inactive state controller 96 may change the value of the inactive state variable parameter n based on a certain type of power supply.

The communication services controller 100 receives user data inputs when a user establishes new types of services, and stores data related to the current service (s). The communication service controller 100 provides input of the maximum permissible delay data to the inactive state loop controller 96 to ensure that the value of the inactive state loop parameter does not increase so that it exceeds the maximum delay allowed for a particular service requested or subscribed by the mobile station. The controller 100 communication services takes into account all of the current subscribed services and determines the maximum delay that may be tolerated with the proper provision of such services. The maximum delay value may limit the value of n, for example, in accordance with the following relation: n = INT (2log (maximum delay / frame duration)).

The inactive cycle controller 96 stores the inactive cycle parameters defined for the mobile station at the current time, as well as for various levels of activity (for example, A2-A4), and provides the current value of the inactive state cycle parameter to the transceiver circuits 92 for transmitting to UDRN, so that UDRN and core networks can use the value of the variable inactive state cycle together with MIMA to determine the appropriate time and method of sending a search call to mobile ntsii. This information may also be stored, for example, in a mobile station switching center (MSC) / visitor location register (RMB) or in another central database. Based on the current values for n, S, and W, the idle cycle controller 96 controls the power output to the transceiver circuits 92 and other mobile station circuits for switching from the low power mode during the inactive state to the higher power mode when the mobile station is activated.

The inactive state / activation procedure of the mobile station (block 200) is described in FIG. Initially, the mobile station can determine the current activity of data transmission, as well as the set activity level (for example, A1-A4) and from this information determine whether the current activity is above or below the threshold (block 202, designated as step (1)). The mobile station may also receive user data entries prioritizing the saving of battery power or short service delay (block 204, designated as step (2)). The mobile station may also determine various maximum delay requirements or one or more services requested or subscribed by the subscriber (block 206, designated as step (3)). The mobile station may also determine the source and / or type of power supply (block 208, designated as step (4)).

The mobile station can also determine similar information from these four steps (1) to (4) for service nodes of multiple core networks if the mobile station is subscribed to services from multiple core networks (block 210). The mobile station then determines the inactive state parameter n, the inactive state cycle S and activation frames W for each core network using the formulas described above, taking into account the information collected in one or more stages (1) - (4) related to to each core network (block 212). The mobile station then determines the activation frames W that best suit the needs of all associated core networks (block 214).

It is also desirable to coordinate the inactive state cycle of the mobile station based on various factors for a plurality of core networks. In accordance with the situation shown for the example in Fig. 9, the mobile station is registered in two nodes 18 and 20 of the core network services, where the corresponding inactive state parameters n1 and n2 for the given mobile station are stored. The mobile station and USDR 30 also store these values of the inactive mode parameters n1 and n2. The values of the parameters of the idle state can be agreed upon by the mobile station and the core network at the last registration of the mobile station in this core network. These parameter values may also be associated with subscription by the mobile station services and may be stored in the register of the source location (ROM) and in the SIM card in the mobile station. When roaming, a mobile station can register with or without changing parameter values. In the latter case, the core network can transfer parameter values from the old MSC / RMV to the new MSC / RMV.

In a preferred embodiment, the inactive and activated frames for the service nodes of the two core networks are synchronized. In the absence of such synchronization, the mobile station may eventually be activated much more often than would be necessary in accordance with the separately selected activation frames W1 and W2 calculated for both core networks. Synchronization can be implemented using the MIMA mobile station and the same algorithm to determine all parameters, except for the inactive mode cycle, and by defining the inactive mode cycle as a power of 2.

Fig. 9 shows an example of various parameters that are stored in the core network service nodes 18 and 20, including the MIMA of the mobile station, the cell of the mobile station, OR-UDR, or the location area, corresponding to the value of the variable parameter n1 or n2 of the inactive state cycle. In this example, the PDMA 30 provides a connection between the mobile station and the packet switching service node 20. USDR 30, not the service node 20 processes the mobile service data of the mobile station. To determine the location of the mobile station to the service node 20 there is no need to use the procedure of sending a search call. Instead, it uses the connection already established by the SPDR 30. The established connection is designated as “SPDR-reference”. As an example, “UDR-reference” indicates a specific connection between the service node 20 and the CKP 32, which is uniquely defined for a given mobile station, for example, a connection of the type SCCP (part of the signaling data collection control), TCP (data transfer control protocol), ATM (asynchronous transfer mode), etc.

The mobile station 36 also stores the data of its MIMA, its current cell, OR-UDR, or the location area and the values of the variable parameters of the inactive state cycle n1 and n2 for two nodes 18 and 20 of the core network services. The current activity level of the mobile station 36 with respect to the circuit switched services node 18 is likely to be relatively low, corresponding to activity level A4. Accordingly, in the USDR 30 it is not known about the connection of the mobile station with the node 18 or the variable parameter n1 of the inactive state cycle is not known. On the other hand, the activity level of the mobile station 36 with respect to the packet switching service node 20 is relatively high, and there is a connection corresponding to the activity level A2. Since there is currently a connection for the packet switching service node 20, the MIMA of the mobile station, its current cell, and the value of the variable inactive state cycle parameter n2, respectively, are known in the DRM 30, respectively, of the packet switching service node 20.

By defining the inactive mode cycle as a power of 2, activation frames for each of the nodes 18, 20 of the services of two core networks are determined as follows: W = (F + k2 ⁿ¹ ) moduloM if n1≤n2, and W = (F + k2 ⁿ² ) moduloM, if n2 <n1, where k is an integer and M is the maximum possible frame number. By defining S and W as a power of 2, the activation time W is synchronized in such a way that when the inactive state required by the service nodes of one of the core networks is activated for the shortest cycle, the mobile station is also periodically activated for a longer inactive state mode required by the node services of another core network. For example, since for a short inactive cycle, the mobile station activates at F, F + 2, F + 4, F + 6, F + 8, ..., and for a longer inactive cycle, the mobile station activates at F, F + 4, F + 8, ..., then the two cycles turn out to be synchronized.

Thus, the variable inactive state provided by the present invention allows for a flexible and selective compromise between saving battery power and quality of service, which can be adjusted by the mobile station itself or by the user or network, as necessary. It is also possible to change the cycle of the inactive state of the mobile station so that it is compatible with various levels of activity of the radio resources that are controlled by the radio access network of the UMTS system. In addition, an alternating inactive state cycle allows the mobile station to efficiently receive independent paging messages from various nodes of the core networks while achieving battery life savings, even if the corresponding periods of the inactive state for these networks are different.

Although the invention is described in connection with what is currently considered the most practical and preferred embodiment, it should be borne in mind that the invention is not limited to the disclosed embodiment, but rather includes various modifications and equivalent configurations covered by the nature and scope of the paragraphs claims
