Abstract
A wireless access terminal is configured to enter into a freeze state where the wireless access terminal temporarily stops decoding a receiving data for a first access network, when the wireless access terminal's modem tunes away from the first access network to monitor signals form a second access network. When the modem tunes back, the wireless access terminal continues processing signals form the first access network without re-initializing with the first access network. When the terminal enters the freeze state, state variables for the terminal's various protocols, including layer 1, layer 2, and modem controller protocols can be stored so that the protocols can continue processing when the modem tunes back, without the need to reinitialize.

Embodiment
Below described in tuning transfer and the tuning recovery routine, implemented the system and method for frozen state.Usually, system and method described below uses in the system that a code division multiple access inserts (CodeDivision Multiple Access).Be appreciated that certainly, system and method described below is not limited to CDMA access system.Therefore example described herein can not be considered as this System and method for is confined to the use of the system or the specific communication protocol of any specific.
Fig. 1 to Fig. 3 is state diagram, in conjunction with the System and method for of enforcement frozen state described herein, set forth the process of using frozen state (freeze state) at idle state protocol (idle state protocol), init state agreement (initialization state protocol) and modulator-demodulator controller protocol (modemcontroller protocol) down respectively.In order to point out that legacy protocol and this paper describe the difference of agreement, corresponding conventional procedure has at first been set forth in the state diagram of Fig. 5 to Fig. 7.
Correspondingly, Fig. 5 is the state diagram of a traditional idle state protocol.Idle state protocol, for example, default idle state agreement (default idle state protocol) and enhancing idle state protocol (enhanced idle state protocol), it is the articulamentum agreement (connection layer protocol) of 1xHRPD (High Rate Packet Data) high-speed grouped data system for example, be used to a wireless access terminal behind access network, before obtaining being connected of opening, provide dormancy/Monitoring and Controlling.Especially, thus traditional idle state protocol need follow the tracks of the program of wireless access terminal approximate location and carry out effective paging, and can preserve energy for the wireless access terminal.As shown in Figure 5, traditional idle state protocol runs in the following one of four states one: idle state 502, monitoring state 504, resting state 506 and be connected the state of foundation 508.
When being in idle state 502, the wireless access terminal waits for an activation instruction, when receiving this activation instruction, and agreement becomes monitoring state 504.When monitoring state 504, this wireless access terminal monitoring control channel and monitoring are from the beep-page message of base station.When needs, the parameter that is stored in the terminal will be upgraded according to the beep-page message that receives in this wireless access terminal.After above process was finished, the base station may send unicast packet (unicast packets) to the wireless access terminal that is in monitoring state 504.
Through after the regular hour, if this wireless access terminal does not receive any beep-page message from the base station, then this wireless access terminal may be transformed into resting state 506.In resting state 506, conserve energy can be come by the closed portion subsystem in this wireless access terminal.When being in resting state 506, the wireless access terminal is not monitored forward channel, base station or Access Network usually, does not allow to send unicast packet to the wireless access terminal.The wireless access terminal periodically returns to monitoring state 504 from resting state 506, checks any beep-page message that whether has the base station to send.When being in monitoring state 504 once more, this wireless access terminal is monitoring control channel, monitors beep-page message, upgrades arbitrarily the parameter from overhead message protocol (overhead messages protocol) when needed.
When being in monitoring state 504, the wireless access terminal may need access network and connect, when a wireless access terminal will connect, then agreement was converted to connect from monitoring state 504 and sets up state 508, will attempt to connect by the base station in the wireless access terminal.If this connection is rejected, perhaps be closed, then this agreement will be converted to monitoring state 504.
Fig. 6 is state diagram, has set forth corresponding traditional init state agreement.The init state agreement also comprises one of four states: idle state 602, network are determined state 604, pilot capture state 606 and synchronous regime 608.In idle state 602, an activation instruction is waited in the wireless access terminal.Determine state 604 in case receive the activation instruction protocol conversion to network, determine in the state 604 that an Access Network with operation is selected in the wireless access terminal at network.In case after selecting an Access Network, this protocol conversion is to pilot capture state 606, in this state, the wireless access terminal attempts to set up a Forward Pilot Channel by the base station of the Access Network of selecting.To setting up Forward Pilot Channel failure, then agreement is got back to network and is determined state 604.If find Forward Pilot Channel, then protocol conversion is to synchronous regime 608.
In synchronous regime 608, the cycle synchronisation of the control channel of wireless access terminal and selected Access Network.In case realize that synchronously, then the wireless access terminal receives synchronization message, makes that the system time of wireless access terminal and selected Access Network is synchronous.If surpass a period of time, perhaps the wireless access terminal can not be synchronous, and protocol conversion is returned network and determined state 604 so.On the contrary, if synchronously as going on of estimating, then protocol conversion is an idle state 602.
Fig. 7 is a state diagram, has set forth a traditional modem controller protocol.Modulator-demodulator controller protocol shown in Figure 7 also comprises one of four states: idle state 702, initial acquisition state 704, little trapped state 706 and state of activation 708.The modulator-demodulator controller protocol is responsible for controlling modem hardware, and as concrete introduction hereinafter, modulator-demodulator comprises searcher (searcher), finger (finger) and radio-frequency antenna resource.Be appreciated that at least in some aspects for example in a CDMA access system, entry " searcher " and " finger " are the resources of the modulator-demodulator of uniqueness.Yet when other Technology Need, other resource also can be controlled by the modulator-demodulator controller protocol.
When being in idle state 702, a pilot capture instruction is waited in the wireless access terminal.In case receive the pilot capture instruction, then protocol conversion is an initial acquisition state 704.When being in initial acquisition state 704, the modulator-demodulator controller will make modulator-demodulator be tuned to a selective channel and pilot tone of search in the frequency spectrum of a qualification.During this period of time, the wireless access terminal lacks correct system timing information.If search for successfully, then protocol conversion is little trapped state 706.Otherwise if the pilot channel in the limiting time can not be found in the wireless access terminal, then idle state 702 is returned in protocol conversion.
After entering little trapped state 706, the modulator-demodulator controller begins the pilot tone that can use at current channel search, and in search, the wireless access terminal will obtain the timing information of some systems by the pilot tone that searches at initial acquisition state 704.When finding an available pilot tone, the modulator-demodulator controller will be assigned a finger in this pilot tone, and be transformed into state of activation 708.
In state of activation 708, the modulator-demodulator controller is searched for available, candidate, adjacent and remaining pilot tone energetically.If find one or more this type of pilot tone, the modulator-demodulator controller will be assigned a finger to each pilot tone so.If the modulator-demodulator controller receives an illegal command when little trapped state 706 or state of activation 708, then idle state 702 is returned in protocol conversion.
As indicated above, if modulator-demodulator is forced to tuning transfer, so invalid modulator-demodulator control protocol in order to monitor a different technology.In case modem resource is available, whole initial acquisition process must be restarted in the wireless access terminal so.For example,, then abandon this call setup in call establishment, thereby cause the long settling time and the waste of resource if interruption has taken place.And beep-page message may have been ignored in the wireless access terminal in abandoning process.In a calling, tuning transfer may cause call release.
Fig. 1 to Fig. 3 is state diagram, set forth and relevant idle condition, init state and the modulator-demodulator controller protocol of enforcement frozen state, make the wireless access terminal can preserve specific state information, make terminal after tuning recovery, get back to a certain protocol.For example, Fig. 1 is a state diagram, set forth the example of an idle state protocol, for example, in conjunction with one of an embodiment default idle state protocol (default idle state protocol) or an enhancing idle state protocol (enhancedidle state protocol).As shown in Figure 1, idle state protocol comprises the one of four states of a traditional idle state protocol.The idle state protocol that is Fig. 1 comprises that an idle state 102, monitoring state 104, resting state 106 are connected the state of foundation 108 with one.In addition, the idle state protocol among Fig. 1 also comprises and three newly-increased states that the frozen state process is relevant certainly, makes the wireless access terminal to economize on resources when tuning transfer and tuning recovery.Above-mentioned three newly-increased states are for freezing suspended state 110, frozen state 112 and being connected frozen state 114.
For example, if a tuning transfer occurs in when agreement is in monitoring state 104, then agreement can be transformed into frozen state 112, and temporarily stops the Overhead Message of monitoring control channel.In case tuning recovery takes place, agreement can be resumed operation and monitoring state 104, and does not need to carry out again whole initial acquisition process.In this case, terminal resource just can be saved.If tuning transfer occurs in to connect and sets up in the state 108, agreement just enters one and connects frozen state 114, and the process that just can hang up foundation when state 108 is set up in connection is up to tuning recovery.And, can not abandon call establishment.Therefore, when tuning recovery takes place and agreement change back connection and sets up state 108 from connecting frozen state 114, holding time and resource significantly are because the call setup process can be recovered when tuning transfer begins initialization.If tuning transfer takes place and this moment Traffic Channel activates, agreement can enter to be freezed suspended state 110 and knows that tuning recovery takes place, and process switch is returned 102 idle states at this moment.And, in tuning transfer, can not discharge this calling or Traffic Channel.
In software program, need to use two extra instructions to control the operation of wireless access terminal, can be controlled at the conversion between the different frozen states of freezing suspended state 110, frozen state 112 and connecting frozen state 114, and the state of idle state 102, monitoring state 104, resting state 106 and the traditional idle state protocol that is connected the state of foundation 108.These new instructions can be that modulator-demodulator freezes control command ModemControl.Freeze and modulator-demodulator and separates and freeze control command ModemControl.Thaw.In an example, if radio frequency (RF) and other any resource are unavailable for current techniques, switch to other technology of monitoring such as wireless access terminal modulator-demodulator controller, when being tuning transfer, modulator-demodulator freezes control command ModemControl.Freeze and is produced by terminal, and is received by agreement shown in Figure 1.If radio frequency (RF) and other resource is available for current techniques arbitrarily, when switching back such as wireless access terminal modulator-demodulator controller, be tuning recovery, modulator-demodulator is separated and is freezed control command ModemControl.Thaw by agreement reception shown in Figure 1.Therefore, freeze control command ModemControl.Freeze if agreement is in monitoring state 104 and receives a modulator-demodulator, agreement will be transformed into frozen state 112.When being in frozen state 112, to separate and freeze control command ModemControl.Thaw if agreement receives a modulator-demodulator, agreement will switch to monitoring state 114 from frozen state 112.Similar, if being in to connect to set up state 108 and receive a modulator-demodulator, agreement freezes control command ModemControl.Freeze, agreement will be transformed into and connect frozen state 114.If agreement receives a modulator-demodulator and separates and freeze control command ModemControl.Thaw, be in simultaneously and connect frozen state 114, then protocol conversion is returned and is connected the state 108 of setting up.Freeze control command ModemControl.Freeze and be in idle state 102 simultaneously if receive modulator-demodulator, then agreement will be transformed into and freeze suspended state 110.Separate and freeze control command ModemControl.Thaw if receive modulator-demodulator, be in simultaneously and connect frozen state 110, idle state 102 is returned in protocol conversion.
Say that further freeze suspended state 110 and receive an activation instruction if agreement is in, then agreement will be transformed into frozen state 112.If agreement is in frozen state 112 and receives an illegal command, then agreement will be changed back and freeze suspended state 110.If receive an illegal command freezing suspended state 110, then ignore this instruction.If agreement is in frozen state 112 and receives one and open link order, then will send a connection request message and be transformed into and connect frozen state 114.Receive one when connecting frozen state 114 and connect rejection or out code if be in, then agreement will be changed back frozen state 112.Receive one when freezing suspended state 110 or connecting frozen state 114 and open link order if be in, then ignore this instruction.If be in one when freezing suspended state 110 or frozen state 112 and receiving an out code, then ignore this instruction.Connect frozen state 114 and receive that a routing update connects when opening indication routeupdate.connectionOpen if be in, agreement is opened connection of loopback indication and is transformed into and freezes suspended state 110.
When terminal enters resting state 106, send illegal command.Furtherly, when being in frozen state 112, will stop monitoring control channel by the specific instruction of sending when accessing terminal.For example, in one embodiment, access terminal and to send an Overhead Message illegal command OverheadMessage.Deactivate and a control channel media access control layer illegal command ControlChannelMac.Deactivate.
If when the wireless access terminal was in frozen state 112 and receives the indication of an Overhead Message update instruction OverheadMessage.Update, then terminal was waited in line this instruction to adjudicate when agreement is got back to monitoring state 104.Furtherly, receive a beep-page message if access terminal, then this terminal will send a connection request message, and, as mentioned above, receive a routing update if access terminal and connect initialization directive RouteUpdate.ConnectionInitiated, then be transformed into the frozen state 114 of connection.
Fig. 2 is a state diagram, has set forth the example of an init state agreement in conjunction with an embodiment.As seen, agreement shown in Figure 2 comprises that traditional idle state 202, network determine state 204, pilot capture state 206 and synchronous regime 208 among the figure.In addition, agreement shown in Figure 2 comprises frozen state 210.When if agreement is in synchronous regime 208, tuning transfer takes place, and then protocol conversion is to frozen state 210.When being in frozen state 210, the modulator-demodulator of wireless access terminal will temporarily stop the Overhead Message of monitoring control channel.In case tuning recovery, for example the wireless access terminal modulator-demodulator switches back initial technology, and then this wireless access terminal will resume operation in synchronous regime 208, and not need to carry out again whole initial acquisition process.
Therefore, freeze control command ModemControl.Freeze if receive a modulator-demodulator when being in synchronous regime 208, protocol conversion then shown in Figure 2 is to frozen state 210.If be in frozen state 210, receiving simultaneously that a modulator-demodulator is separated freezes control command ModemControl.Thaw, and then agreement will be changed back synchronous regime 208.When being in frozen state 210, the wireless access terminal can stop all timers and send a control channel media access control layer illegal command ControlChannelMAC.Deactivate.A control channel media access control layer illegal command ControlChannelMAC.Deactivate may make the modulator-demodulator of all wireless access terminals stop the Overhead Message of monitoring control channel.
Fig. 3 is a state diagram, has set forth a modulator-demodulator controller protocol example in conjunction with an embodiment.And agreement shown in Figure 3 comprises traditional idle state 302, initial acquisition state 304, little trapped state 306 and state of activation 308.In addition, agreement shown in Figure 3 comprises initial acquisition frozen state 310 and frozen state 312.Introducing initial acquisition frozen state 310 is in order to handle because the loss of the radio frequency resource that the different technology of monitoring causes with frozen state 312.
Specifically, when radio frequency and other resource are taken by another technology, the modulator-demodulator controller can be transformed into any one state in initial acquisition frozen state 310 or the frozen state 312, and the variation of preserving all modem states, the process of hang-up modulator-demodulator.If radio frequency resource takies when occurring in little trapped state 306 or state of activation 304, then send a modulator-demodulator controller and freeze command M odemController.Freeze to all other protocol stacks, comprise idle state protocol and initialization state protocol, and init state agreement, as illustrated in figs. 1 and 2, notify these agreements all to be transformed into the frozen state agreement.
When but radio frequency or other resource become the time spent, it is tuning recovery, the modulator-demodulator controller protocol can store the variation of all modulator-demodulators, and from initial acquisition frozen state 310 or the frozen state 312 modulator-demodulator process that conversion is returned and continuation is hung up before.Then send a modulator-demodulator and separate and freeze control command ModemController.Thaw, notify these agreements to come out from the frozen state protocol conversion to all other stack agreements that comprise idle state protocol and init state agreement.
Therefore, if when the modulator-demodulator controller protocol is in initial acquisition state 304, then agreement will be transformed into initial acquisition frozen state 310 according to the tuning transfer that takes place.At this constantly, all initial rangings of preserving for example variation of CDMA Channel and frequency change.All search of carrying out of temporary suspension.Invalid and discharge radio frequency that current techniques uses and other any resource to monitor second technology.When tuning recovery took place, stored search changed again, and the modulator-demodulator controller protocol can be changed back initial acquisition state 304, can activate all radio frequency resources that initial technology is used, and the initial acquisition search of state 304 can continue.
Tuning transfer takes place in agreement when being in little trapped state 306 or state of activation 308.Agreement can be transformed into frozen state 312, and preserve all modem state and change, for example CDMA Channel and frequency change, and be in activation, the candidate, adjacent and the pilot frequency information that keeps.The search that temporary suspension is all, all radio frequency resources that initial technology is used can carry out invalid and release.Send a modulator-demodulator controller to all other stack agreements and freeze command M odemController.Freeze, for example idle state protocol and init state agreement.
When tuning recovery takes place, can store modem state changes, the modulator-demodulator controller protocol can be changed back little trapped state 306 or state of activation 308, can activate all radio frequency resources that initial technology is used, and on-line search and finger arrangement continue.And separate to other stack agreement sending modem and to freeze control command ModemController.Thaw.
Correspondingly, by using the described process of Fig. 1 to Fig. 3, when the temporary transient tuning transfer in wireless access terminal, when removing to monitor a different technologies at short notice, the wireless access terminal does not need through whole initial acquisition process.Further,, can preserve Radio Resource, reduce call set-up time because call establishment is not disturbed in tuning transfer process.Be in when accessing terminal traffic channel state a calling,, do not need to discharge this calling when tuning transfer takes place.The paging number of losing to the wireless access terminal also can drop to minimum.
