Wireless communication device and communication operation coordination method

The present invention relates to radio frequency resource configuration for wireless communication, and in particular to radio frequency resource configuration when communicating with multiple service networks.

As global demand for ubiquitous computing and networking continues to rise, many wireless communication technologies have emerged, such as Global System for Mobile communications (GSM) technology, general packet wireless services (General Packet) Radio Service, GPRS) technology, Enhanced Data rates for Global Evolution (EDGE) technology, Universal Mobile Telecommunications System (UMTS) technology, code division multiplexing-2000 (Code Division Multiple) Access 2000, CDMA-2000) technology, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology, Worldwide Interoperability for Microwave Access (WiMAX) technology, Long Term Evolution (LTE) technology, Long Term Evolution-Advanced (LTE-A) technology, and Time-Division LTE (TD-LTE) technology, and the like. In general, a mobile phone only supports one type of wireless communication technology, and provides wireless communication technology to provide users with the flexibility to communicate anytime, anywhere. Especially in today’s business world, mobile phones are already doing business. A convenient tool that is indispensable. For business people, they generally choose to have a business-only mobile phone because they still need to deal with business affairs when they leave the office or even when they go abroad. Alternatively, for other users, an additional mobile phone may be selected to save/control overhead on the wireless service (including voice calls and/or data service charges). But having two or more mobile phones at the same time is a hassle. In particular, users need to carry multiple mobile phones with them, and they need to frequently switch between different mobile phones. In order to make it easier for users to have multiple subscriber numbers, a dual- or multi-card mobile phone has been introduced, which may have one or more wireless communication modules that support the same or different communication technologies (eg It can support GSM and UMTS mobile phones, and use different user numbers for wireless transmission and reception. A dual- or multi-card mobile phone enables multiple wireless communication modules to operate simultaneously, and at the same time, can receive a call from its corresponding subscriber number from any wireless communication module. Therefore, the user can use the dual or multi-card mobile phone to separate business and private purposes according to different user numbers and bills, or use an extra user number for roaming when going abroad.

For dual-card or multi-card mobile phones with only a single transceiver, only one wireless communication module can use the transceiver to obtain network resources at the same time, while the other wireless communication module cannot access the transceiver. Specifically, because these wireless communication modules operate independently and lack proper communication mechanisms between each other, the wireless communication module that cannot access the transceiver cannot know that the transceiver is currently being used by another wireless communication module. Occupied. For example, the only transceiver for a dual-card mobile phone is the first The line communication module occupies a packet-switched (PS) data service, such as: Multimedia Messaging Service (MMS), Instant Messaging Service (IMS), and File Transfer Protocol (File Transfer). Protocol, FTP) file transfer or web browsing and so on. At this time, when the service network related to the second wireless communication module initiates a mobile-terminated (MT) call for the second wireless communication module, the second wireless communication module may be unable to access and receive the call. The device misses the MT call, and the second wireless communication module is unable to receive the paging message from the service network, and cannot know the entry of the MT call.

Therefore, there is a need for a more flexible way to manage operations between multiple wireless communication modules associated with multiple subscriber identification cards, such that the second wireless communication module is in the first wireless module. The packet exchange data service can still receive MT calls from the service network.

To this end, the present invention provides at least one wireless communication device and a communication operation coordination method.

One of the roads is called to call or to measure a plurality of candidate cells located in the first service network, to perform wireless transmission and reception with a second service network through a second channel, and to the wireless transceiver system. For a predetermined procedure The above-mentioned wireless transmission and reception is kept interrupted by the monitoring of the above first channel.

Another embodiment of the present invention provides a communication operation coordination method, which is suitable for coordinating communication operations with different service networks in a wireless communication device. The communication communication coordination method includes the steps of: monitoring a first channel associated with a first service network to receive a called call from one of the first service networks or measuring a plurality of locations located in the first service network a candidate cell; performing wireless communication with a second service network through a second channel; and maintaining the wireless transceiver not interrupted by monitoring of the first channel when the wireless transceiver is executed for a predetermined program .

A typical SIM card includes user account information, an International Mobile Subscriber Identity (IMSI), and a SIM Application Toolkit (SAT) instruction set. In addition, the SIM card also provides space to store phone book contacts. The Micro-Processing Unit (MCU) of the baseband chip (known as the Baseband MCU in the text) can interact with the SIM card's microprocessor unit (known as SIM MCU in the text) to insert the SIM card. Capture data or instructions from the SIM application development tool. After the SIM card is inserted, the mobile station completes the programming. The SIM card can also be set to display a list of features specific to the personal service. The SIM card further stores the code of the Home Public-Land-Mobile-Network (HPLMN) to indicate the network operator associated with it, wherein the HPLMN code contains the action country code (Mobile Country) Code, MCC) and the Mobile Network Code (MNC). Further, the International Mobile Subscriber Identity is associated with one of the corresponding users in the GSM or UMTS system and is a unique number. Mobile station can be international The mobile subscriber identity code is transmitted to the GSM or UMTS network to obtain other details of the network user from the Home Location Register (HLR), or from the Visitor Location Register (Visitor Location Register, The VLR) obtains detailed information about the replication of the user of the network. A typical International Mobile Subscriber ID is 15 digits or less (for example, the International Mobile Subscriber ID used by South African operator MTN is 14 digits long). The first 3 digits are the action country code, and the next 2 digits (European regulations) or 3 digits (North American regulations) are the mobile network code, and the remaining digits are the corresponding users in the GSM or UMTS system. Mobile Subscriber Identification Number (MSIN).

The USIM card is used in the UMTS system (or 3G communication system) for mobile communication between the mobile station and the network. The USIM card stores user account information, international mobile user ID, and the USIM Application Toolkit (USAT) instruction set, and provides space for storing phone book contacts and text messages. The USIM card can further store the code of the local public land mobile network to indicate the network operator associated with it. The Baseband MCU can interact with the USIM card's microprocessor unit (known as the USIM MCU in the post) to capture the data from the inserted USIM card or the USIM application development tool. It is worth noting that the phone book contact function on the USIM card has been greatly improved compared to the SIM card. For the purpose of authentication, the USIM card can store a long-term pre-shared key K, which is shared by the USIM card and the Authentication Center (AuC) on the network side. The USIM MCU can use the window mechanism to confirm whether a serial number falls within a reasonable Within the scope to avoid replay attacks. The USIM MCU is also responsible for generating session keys CK and IK for the privacy and integrity algorithms (or A5, A3 algorithms) in the KASUMI block coding of the UMTS system. After inserting the USIM card, the mobile station completes the programming. In addition, the R-UIM or CSIM card is a mobile station for synchronous code division multiplexing access, which is equivalent to the SIM card used in the GSM system and the UMTS system except for the synchronous code division multiplexing access network. USIM card used. The R-UIM or CSIM card is structurally compatible with the SIM card used by the GSM system and provides a similar security mechanism for the user and the synchronous code division multiplex access network.

Figure 5 is a schematic diagram showing the call control (CC) of the mobile station receiving the called call in the GSM/GPRS/EDGE system. The call control is one of the Connection Management (CM) entities and includes procedures for establishing, controlling, and terminating calls. A called call is a call originating from or outside the public land mobile network and calling the mobile station. When a called call for a mobile station is initiated, the Mobile Switching Center (MSC)/Visitor Location Register can command the Base Station Subsystem (BSS) to page the mobile station. Because the mobile switching center/visitor location register does not know which base station the mobile station resides in the base station subsystem, a paging message is sent throughout the location area (LA). The mobile station can receive the paging request message (labeled as PAG_REQ in FIG. 5) through the paging channel, and recognize that the paging request message is based on the Temporary Mobile Subscriber Identity (TMSI) or the International Mobile Subscriber Identity (ID). For it. Then, the mobile station can pass through The Random Access Channel (RACH) transmits a channel request message (labeled as CHAN_REQ in Figure 5) to the base station subsystem, and the base station subsystem transmits the configuration message through the Access Grant Channel (AGCH). (marked as IMM_ASS_COM in Figure 5) in response to the mobile station. The configuration message is used to configure a Stand-Alone Dedicated Control Channel (SDCCH) for the mobile station to be used for signaling with the service network before configuring the Traffic Channel (TCH). . So far, the service network does not know that the mobile station is the target mobile station that it wants to page. It only knows that the mobile station wants to access the service network. For the received configuration message, the mobile station immediately switches to the configured independent dedicated control channel and transmits a paging response message (labeled PAG_RES in Figure 5) to the serving network via a separate dedicated control channel. At this point, the service network knows that the mobile station is the mobile station that it wants to page, so the initial setting of the called call is completed here.

Before the service network provides services to the mobile station, the mobile station needs to authenticate itself to the service network. The base station subsystem transmits a verification request message (labeled AUTH_REQ in Figure 5) to the mobile station including a random number (labeled RAND in Figure 5), which is generated by the local location register for use by the local location register. Verify a 128-bit random challenge. The mobile station calculates a suitable Signed Response (SRES) based on the random number, and transmits the authentication backhaul to the base station subsystem through the verification response message (labeled as AUTH_RESP in FIG. 5). Next, the base station subsystem checks the authentication checkback. If the authentication checkback is correct, the mobile station passes the authentication and allows it to access the service network. Once certified After completion, the mobile switching center/visitor location register can command the base station subsystem and the mobile station to switch to the ciphering mode through the security mode command message (labeled CIPH_MOD_CMD in FIG. 5). When the mobile station has entered the encryption mode, the visitor location register configures a new temporary mobile subscriber identity code to the mobile station, and then the mobile switching center transmits a setup message (labeled SETUP in Figure 5) to the mobile station through the base station subsystem. The establishment of the channel is initiated by Taiwan. The setup message may include Calling Line Identification Presentation (CLIP), which is the calling number. The mobile station transmits a call confirmation message (labeled CALL_CON in Figure 5) in response to the received setup message, the call confirmation message is used to indicate that the mobile station can establish the required connection, and the call confirmation message can be via the base station. The system is forwarded to the mobile switching center. Next, the flow proceeds to the call setup procedure, and the base station subsystem transmits a configuration command message (labeled ASS_CMD in FIG. 5) to the mobile station through the configured independent dedicated control channel. The configuration command message is used to configure the data transmission channel to the mobile station. Upon receipt of the configuration command message, the mobile station immediately switches to the data transmission channel and transmits a configuration completion message (labeled ASS_COM in Figure 5) via the Fast Associated Control Channel (FACCH) in response to the base station subsystem ( The fast correlation control channel is used for signaling and belongs to a time slot on the data transmission channel, that is, all the signals on the data transmission channel are performed on the fast correlation control channel). Once the mobile station completes the establishment of the data transmission channel, it will start ringing the incoming call. Afterwards, the mobile station transmits a warning message (labeled ALERT in Figure 5) to the mobile switching center through the fast relevant control channel, and then the base station subsystem transmits the police through the Public Switched Telephone Network (PSTN). The message is forwarded to the caller (if the mobile station and the caller are on a different public telephone network), then the ringtone is heard on the caller. When the user of the mobile station answers the call (pressing a specific button or touching a specific button displayed on the screen, or answering it by other means), the mobile station transmits a connection message (labeled CON in Figure 5) To the mobile switching center, the connection message is forwarded by the switching device of the calling terminal to initiate the call. Finally, the mobile switching center replies to the connection confirmation message (labeled CON_ACK in Figure 5) to the mobile station to complete the establishment of the called call. The call control of the UMTS, TS-SCDMA, or LTE system is similar to the call control of the above GSM system, and therefore will not be described herein.

Figure 6 is a diagram showing an example of a packet access procedure for a GPRS/EDGE system. Initially, the mobile station transmits a PACKET CHANNEL REQUEST message to the base station subsystem in the GPRS/EDGE system through a Packet Random Access Channel (PRACH) or a Random Access Channel (RACH). The packet channel request message includes parameters indicating the radio resource and access type requested by the mobile station. In a single-stage packet access procedure, the base station subsystem can respond to the mobile station by transmitting a packet access grant channel (PAGCH) or an access grant channel (AGCH) to transmit a PACKET IMMEDIATE ASSIGNMENT message. The packet immediate allocation message includes information about a radio resource reserved for uplink data transmission on a Packet Data Channel (PDCH). After the packet is successfully received, the mobile station can start data transmission. In the two-stage packet access procedure, the base station subsystem can access the promise channel or save through the packet. The promise channel transmits the packet to immediately assign a message in response to the mobile station, wherein the packet immediate assignment message includes information about the radio resource reserved for the PACKET RESOURCE REQUEST message to be transmitted later. The packet resource request message includes complete information about the uplink data transmission. Upon receiving the packet resource request message, the base station subsystem transmits a PACKET RESOURCE ASSIGNMENT message in response to the mobile station, wherein the packet resource configuration message includes a correlation of the radio resource reserved for uplink data transmission on the packet data channel. News. After successfully receiving the packet resource configuration message, the mobile station can start data transmission.

FIG. 7 is a schematic diagram showing channel scheduling for a mobile station that is monitoring a paging channel of a 3G circuit switch (CS) to perform a 2G packet access procedure according to an embodiment of the invention. The mobile station (e.g., mobile station 200, 300 or 400) described in this embodiment can support simultaneous communication with the GPRS/EDGE system and the UMTS system. In particular, the mobile station uses a first subscriber identity card (labeled SIM-Y in Figure 7) to associate with the UMTS system to monitor the paging channel for 3G circuit switching and to use the second subscriber identity card (in Figure 7 Labeled as SIM-X) is associated with the GPRS/EDGE system to perform a 2G packet access procedure. Specifically, the mobile station needs to continuously listen to the 3G paging channel to receive paging messages from the UMTS system, and the mobile station may need to listen to the paging indication channel in each paging occasion of the discontinuous reception (DRX) cycle. (Paging Indicator Channel, PICH) or paging channel (PCH) to receive paging messages. As shown in Figure 7, the RF resource configuration is encountered before the 2G packet access procedure is executed. The paging period is assigned to the 3G paging channel, which means paging the channel or paging channel. During the 2G packet access procedure, when the mobile station has transmitted the packet channel request message and is waiting for the packet to immediately allocate the message, the radio resource configuration is assigned to the 2G access promise channel, and when the mobile station is not waiting for the packet, it is immediately allocated. In the case of a message, the RF resource configuration is assigned to the 3G paging channel. In other words, the 2G access promise channel is protected from being interrupted by 3G paging. When receiving the paging message, the mobile station determines whether the paging message is for it. If so, the mobile station can suspend the 2G packet access procedure to establish a connection with the UMTS system to answer the called call; The paging message is not directed to it, the mobile station can enter the 3G idle mode for the UMTS system to wait for the next paging period, and the radio resource configuration can be used for other required operations, including with the GPRS/EDGE system and the UMTS system. Any job associated with it.

The mobile station can measure the signal quality and/or signal strength of the candidate cells, and then use the measurement result (measured signal quality and/or signal strength) as a judgment factor to perform the handover procedure and the cell reselection. program. If the mobile station is in the idle mode, it will receive a cell broadcast information about the neighboring cell, for example, the frequency of the broadcast control channel of the neighboring cell. In the GSM/GPRS/EDGE system, the mobile station can receive information of neighboring cells and measure Received Signal Strength Indications (RSSIs) of the broadcast control channels of neighboring cells, wherein each received signal strength indicator It is used to indicate the broadband received power in the GSM channel band. In the UMTS system, even if neighboring cells use the same wideband frequency, they can still use the scramble code they use. (scrambling codes) for differentiation, and the mobile station continuously monitors the Common Pilot Channel (CPICH) to measure power levels, such as: power noise ratio (Ec/No), received signal power (Received Signal) Code Power, RSCP), etc., the information obtained by monitoring can be used to evaluate which UMTS cells are used as candidate cells in cell reselection.

In an embodiment, the mobile station may initiate a cell reselection procedure to maintain its mobility in the same or different GSM/GPRS/EDGE systems, so-called intra-Radio Access Technology, intra- RAT) cell reselection procedure, or the mobile station may also initiate a cell reselection procedure to transfer its mobility from the GSM/GPRS/EDGE system to the UMTS system or from the UMTS system to the GSM/GPRS/EDGE system, so-called Inter-radio access technology (inter-RAT) cell reselection procedure. Specifically, the mobile station can decide to perform the cell reselection procedure based on the reselection criteria of the radio access technology used. For example, in the GSM system, the reselection criteria include a C1 criterion and a C2 criterion; in the UMTS system, the reselection criterion includes a cell ordering criterion R. For a detailed description of the C1/C2 guidelines in the GSM system, please refer to the standard specification TS 05.08 (before version 4) or TS 45.008 (3rd) developed by the 3rd Generation Partnership Project (3GPP). For a detailed description of the cell ranking criteria R in the UMTS system, please refer to the standard specification TS 25.304 developed by the 3rd Generation Mobile Communications Partner Program. In addition, the mobile station can also receive system information broadcasted from the serving cell and the neighboring cell to perform cell reselection. Specifically, the frequency of the broadcast control channel of the neighboring cell is obtained according to the system information broadcasted by the serving cell, and then the neighboring cell is received according to the frequency of the broadcast control channel. System information broadcasted.

Since the reception of system information plays a very important role in the cell reselection procedure, it is necessary to avoid the reception of system information to be associated with jobs of different service networks (for example, paging jobs, measurement jobs, and cell scan jobs, etc.) Interrupted. FIG. 8 is a schematic diagram showing a paging channel for performing channel scheduling in a 2G packet transmission mode to monitor 3G circuit switching according to an embodiment of the invention. The mobile station (e.g., mobile station 200, 300, or 400) described in this embodiment can support simultaneous communication with the GPRS/EDGE system and the UMTS system. In particular, the mobile station uses a first subscriber identity card (labeled SIM-X in Figure 8) to associate with the GPRS/EDGE system for packet exchange data services (eg, receiving and receiving emails, browsing web pages, etc.), and A second subscriber identity card (labeled SIM-Y in Figure 8) is associated to the UMTS system. That is to say, the mobile station is in the 2G packet transmission mode in the GPRS/EDGE system, and is in the 3G idle mode in the UMTS system. When set in the 3G idle mode, the mobile station needs to continuously listen to the 3G paging channel to receive the paging message from the UMTS system, and the mobile station may need to listen to the paging indication channel or the paging channel to receive the paging during the paging period of each discontinuous reception period. message. As shown in FIG. 8, before the cell reselection procedure needs to be performed during the packet exchange data service associated with the GPRS/EDGE system, if the mobile station does not need to receive the paging message, the radio resource configuration is assigned to the 2G packet data channel. The packet exchange data service is performed, and then, in each paging period, the radio resource configuration is assigned to the 3G paging channel, that is, the paging indication channel or the paging channel. When receiving a paging message, the mobile station will determine whether the paging message is directed to it, and if so, the mobile station can pause and The packet exchange data service associated with the GPRS/EDGE system receives the called call from the UMTS system; conversely, if the paging message is not directed to it, the mobile station can switch back to the packet switched data service, and the radio resource configuration can be used for other Required work, including any work associated with the GPRS/EDGE system and the UMTS system. However, in the process of the cell reselection procedure, when it is required to receive system information of the target cell and/or the neighboring cell, the radio resource configuration is assigned to the 2G broadcast control channel, and when the target cell and/or the neighboring cell are not required to be received. For system information, the RF resource configuration is assigned to the 3G paging channel during each paging period and to the 2G packet data channel at other times. It should be noted that, in the process of performing the cell reselection procedure, since the time of receiving the system information of the target cell and/or the neighboring cell overlaps with the paging period, the radio resource configuration is assigned to the 2G broadcast control channel instead of 3G. Paging channel. In other words, the 2G broadcast control channel is protected from being interrupted by 2G packet exchange data services and 3G paging operations. After the cell reselection procedure is completed, the radio resource configuration is as described above, and is preferentially assigned to the 3G paging channel instead of the 2G packet data channel.

In the process of the cell reselection procedure in the GSM/GPRS/EDGE system, in addition to collecting broadcast system information from the broadcast control channel, the mobile station may also need a frequency correction channel in the target base station subsystem (Frequency Correction). Channel, FCCH) searches for Frequency Correction Burst (FB) and/or searches for Synchronization Burst (SB) on the Synchronization Channel (SCH). The mobile station uses a frequency correction burst to synchronize with the frequency of the target base station subsystem, and uses synchronization. The burst is synchronized with the timing of the target base station subsystem. It will be apparent to those skilled in the art how to perform channel scheduling in accordance with the embodiments described in Figures 7 and 8 to avoid frequency correction bursts and/or synchronization burst searches being associated to The specific jobs of different service networks (for example, paging jobs, measurement jobs, and cell scan jobs, etc.) are interrupted.

In another embodiment, the cell reselection procedure can be initiated by the serving network. Specifically, if the serving network wants to transfer the mobile station from one cell to another in the same or different GSM/GPRS/EDGE system, the so-called The Packet Cell Change Order (PCCO) procedure, the service network may transmit a PACKET CELL CHANGE ORDER message to the mobile station, wherein the packet cell change command message includes the mobile station needs to search And related information synchronized with the target cell. Alternatively, if the serving network wants to transfer the mobile station from the UMTS system to the GSM/GPRS/EDGE system, the so-called Cell Change Order (CCO) procedure, the serving network can transmit a cell change command (CELL CHANGE ORDER) ) Message to the mobile station. Figure 9 is a diagram showing an example of a procedure for performing a packet cell change command procedure for a mobile station associated with a GSM/GPRS/EDGE system and in an idle mode. After the mobile station resides in the current base station subsystem and enters the idle mode, the current base station subsystem transmits the packet to the mobile station through the access promise channel, and the packet immediately allocates a message to configure a packet-related control channel (Packet Associated). Control Channel, PACCH) is used by the mobile station to communicate with the service network. When the packet is received immediately, the mobile station will follow the setting control channel. Then, the current base station subsystem transmits the packet measurement command through the packet related control channel. The (PACKET MEASUREMENT ORDER) message is sent to the mobile station, wherein the packet measurement command message includes information required by the mobile station to measure the cell reselection procedure for network control. Upon receiving the packet measurement command message, the mobile station replies with a PACKET CONTROL ACKNOWLEDGEMENT message to the current base station subsystem to confirm that it has received the packet measurement command message. Then, the mobile station performs measurement based on the information carried in the packet measurement command message. Specifically, the mobile station measures the received signal strength indicator of the broadcast control channel for the candidate cell indicated by the information in the packet measurement command message. After the measurement is completed, the mobile station transmits a channel request (CHANNEL REQUEST) message to the current base station subsystem through the random access channel to request the RF resource to configure the return measurement result. The current base station subsystem then responds with an immediate assignment (IMMEDIATE ASSIGNMENT) message to assign a radio resource configuration. When receiving the immediate assignment message, the mobile station reports the measurement result to the current base station subsystem through the PACKET MEASUREMENT REPORT message. Based on the measurement results, the service network decides to transfer the mobile station from the current base station subsystem to another target base station subsystem. Therefore, the current base station subsystem transmits a packet cell change command message to the mobile station, wherein the packet cell change command message includes information about the target base station subsystem, for example, the absolute radio frequency channel number of the target base station subsystem (Absolute Radio Frequency Channel) Number, ARFCN), and Base Station Identity Code (BSIC) and so on. Finally, the mobile station collects the system information of the target base station subsystem according to the information carried in the packet change command message, and then switches to the target base station subsystem according to the collected system information. System. It should be noted that in the process of collecting system information of the target base station subsystem, the radio resource configuration is preferentially assigned to the broadcast control channel of the target base station subsystem, as shown in FIG.

Alternatively, if the packet cell change command procedure shown in FIG. 9 is a blind packet cell change command procedure (ie, the mobile station does not perform measurement and synchronization operations before performing the packet cell change command procedure), then Before switching to the target base station subsystem, the mobile station may need to search for frequency correction bursts on the frequency correction channel of the target base station subsystem and/or search for synchronization bursts on the synchronization channel. The mobile station uses frequency correction bursts to synchronize with the frequency of the target base station subsystem and uses synchronization bursts to synchronize with the timing of the target base station subsystem. It will be apparent to those skilled in the art how to perform channel scheduling in accordance with the embodiments described in Figures 7 and 8 to avoid frequency correction bursts and/or synchronization burst searches being associated to The specific jobs of different service networks (for example, paging jobs, measurement jobs, and cell scan jobs, etc.) are interrupted.

10A and 10B are diagrams showing an example of a cell change command procedure performed by a mobile station associated with a GSM/GPRS/EDGE system and in a wired mode. The connection mode may be a cell dedicated channel mode or a cell transfer access channel mode. In this embodiment, the mobile station is first connected to the UMTS system and then to be transferred from the UMTS system to the GSM/GPRS/EDGE system. When the UMTS system decides to transfer the mobile station to the GSM/GPRS/EDGE system, the serving radio network controller (serving RNC) in the UMTS system transmits the UTRAN cell change command (CELL CHANGE ORDER FROM UTRAN). Message to the mobile station, the message includes at least Information about the requested target base station subsystem in the GSM/GPRS/EDGE system. The mobile station then switches to the target base station subsystem based on the information in the message. Specifically, the mobile station can receive system information broadcast by the target base station subsystem on the broadcast control channel, and the system information can be required information for the mobile station to reselect to the target base station subsystem. It should be noted that when the system information of the broadcast needs to be received, the radio resource configuration is preferentially assigned to the broadcast control channel, as shown in FIG. After successfully switching to the target base station subsystem, the mobile station initiates a routing area update by transmitting a Routing Area Update Request (ROUTING AREA UPDATE REQUEST) message to the Serving GPRS Support Node (SGSN) of the target base station subsystem. The program includes a Packet Temporary Mobile Subscriber Identity (P-TMSI) with a mobile station, and a routing area identifier that the mobile station stays before receiving the UTRAN cell change command message. When the UTRAN cell change command message is transmitted to the mobile station, the packet body is transferred to the SGSN in the GSM/GPRS/EDGE system by the serving radio network controller in the UMTS system. Specifically, the SGSN in the GSM/GPRS/EDGE system transmits a message requesting a radio network controller (SRNC CONTEXT REQUEST) message to request the transfer of the packet context. Then, in response to the context request message of the serving radio network controller, the serving radio network controller in the UMTS system returns a message to the SGSN of the Serving Radio Network Controller (SRNC CONTEXT RESPONSE) message. The SGSN in the GSM/GPRS/EDGE system transmits the data transfer command of the serving radio network controller when receiving the context response message from the serving radio network controller (SRNC DATA FORWARD COMMAND) message to initiate the transfer of the packet data. After the transfer of the packet data is completed, the SGSN in the GSM/GPRS/EDGE system transmits an Iu Release Command (IU RELEASE COMMAND) message to request the serving radio network controller in the UMTS system to release the Iu connection between them and The relevant radio resources of the Iu connection. In response to the Iu release command message, the serving radio network controller in the UMTS system transmits an Iu Release Complete (IU RELEASE COMPLETE) message to the SGSN in the GSM/GPRS/EDGE system. Next, the Iu connection between the serving radio network controller in the UMTS system and the SGSN in the GSM/GPRS/EDGE system and the associated radio resources of the Iu connection are released. Thereafter, the SGSN in the GSM/GPRS/EDGE system replies with a ROUTING AREA UPDATE ACCEPT message to the mobile station to confirm the routing area update request, wherein the routing area update accept message may include a temporary packet of the mobile station. Mobile User ID. When receiving the routing area update accept message, the mobile station further transmits a ROUTING AREA UPDATE COMPLETE message to the SGSN in the GSM/GPRS/EDGE system to inform the acknowledgment of the routing area update accept message, and then ends. The community changed the command procedure.

Alternatively, in the cell change command procedure shown in FIG. 10A and FIG. 10B, if the mobile station does not perform the over-testing and synchronization operation for the target base station subsystem before receiving the UTRAN cell change command message, the mobile station may It is necessary to search for a frequency correction burst on the frequency correction channel of the target base station subsystem and/or search for the same on the synchronization channel before receiving the system information broadcast on the broadcast control channel of the target base station subsystem. A step burst in which the mobile station uses a frequency correction burst to synchronize with the frequency of the target base station subsystem and uses a synchronization burst to synchronize with the timing of the target base station subsystem. It will be apparent to those skilled in the art how to perform channel scheduling in accordance with the embodiments described in Figures 7 and 8 to avoid frequency correction bursts and/or synchronization burst searches being associated to The specific jobs of different service networks (for example, paging jobs, measurement jobs, and cell scan jobs, etc.) are interrupted.

Figure 11 is a diagram showing an example of a Packet-Switched Hand Over (PSHO) procedure performed by a mobile station associated with a GPRS/EDGE system. In this embodiment, the mobile station first connects to the GPRS/EDGE system through the source base station subsystem to obtain downlink/uplink data services. When the source base station subsystem decides to hand over the mobile station to the target base station subsystem under the same SGSN, it transmits a PS HANDOVER REQUIRED message to the SGSN to request the handover mobile station. In response to the packet exchange handover request message, the SGSN transmits a PS HANDOVER REQUEST message to the target base station subsystem to request that resources be reserved for the mobile station. After the required resources are reserved, the target base station subsystem replies to the PS HANDOVER REQUEST ACKNOWLEDGE message to the SGSN to inform the acknowledged packet exchange handover request message. Upon receiving the packet exchange handover request acknowledgement message, the SGSN begins to relay the data packet of the downlink/uplink data service requested by the mobile station to the target base station subsystem. After the data packet is delivered, the SGSN transmits a PS HANDOVER REQUIRED ACKNOWLEDGE message to the source base station subsystem in response to the above. The packet exchanges the delivery request message. Then, the source base station subsystem transmits a PS HANDOVER COMMAND message to the mobile station, wherein the packet exchange handover command message includes resource information configured for the mobile station and system resource information of the target base station subsystem. With the system resource information of the target base station subsystem, the mobile station can access the configuration resources without performing a signaling operation on the general control channel. When receiving the packet exchange handover command message, the mobile station first suspends the ongoing downlink/uplink data service, and then returns a PACKET CONTROL ACKNOWLEDGEMENT message to the source base station subsystem to inform the acknowledgement packet exchange handover command. message. In this embodiment, since the mobile station does not obtain the timing advance information of the target base station subsystem before leaving the source base station subsystem, the mobile station needs to transmit the packet exchange handover access through the packet data channel (PS HANDOVER ACCESS). The message is sent to the target base station subsystem to obtain the advance timing of the target base station subsystem. When receiving the packet exchange handover access message, the target base station subsystem will reply the PACKET PHYSICAL INFORMATION message to the mobile station through the packet data channel, and then transmit the packet exchange handover completion (PS HANDOVER COMPLETE) message to the mobile station. The SGSN then ended the packet exchange handover procedure. Once it is known that the packet exchange handover has been completed, the SGSN will only forward the downlink data packet to the target base station subsystem, and the resources configured by the source base station subsystem for the mobile station will be released. At the same time, once the mobile station obtains the advanced timing information of the target base station subsystem, it can transmit the normal burst and continue the suspended downlink/uplink data service. It is worth noting that in the packet exchange handover procedure, when the mobile station transmits the packet exchange When the message is accessed and waiting for the packet entity information message, it can be ensured that the packet data channel is not interrupted by a specific job associated with the UMTS system (eg, paging, measurement, and cell scan jobs, etc.). For those skilled in the art, how to perform channel scheduling according to the embodiments described in FIG. 7 and FIG. 8 to avoid the downlink/uplink data service being associated with a specific operation of a different service network (eg, paging, measurement, and cell scan jobs, etc.) are interrupted.

Alternatively, in the packet exchange handover procedure shown in FIG. 11, if the mobile station does not perform over-testing and synchronization operations for the target base station subsystem before receiving the packet exchange handover command message, the mobile station may need to Searching for frequency correction bursts on the frequency correction channel of the target base station subsystem and/or searching for synchronization bursts on the synchronization channel before switching to the target base station subsystem, wherein the mobile station uses frequency correction bursts to target the base station subsystem The frequency is synchronized and a synchronization burst is used to synchronize with the timing of the target base station subsystem. It will be apparent to those skilled in the art how to perform channel scheduling in accordance with the embodiments described in Figures 7 and 8 to avoid frequency correction bursts and/or synchronization burst searches being associated to The specific jobs of different service networks (for example, paging jobs, measurement jobs, and cell scan jobs, etc.) are interrupted.

Figure 12 is a diagram showing an example of a procedure for performing a connection establishment procedure for a mobile station associated with a UMTS system. First, the connection establishment procedure starts from the mobile station transmitting a RRC CONNECTION REQUEST message to the UTRAN through the random access channel, and the message includes the identification code of the mobile station (for example, the temporary mobile subscriber identity code) , packet temporary action user ID, or international mobile user ID, etc.) and establishment Reason (for example: general call, streaming service, emergency call, registration, or location update, etc.). Upon receiving the connection request message of the RRC, the UTRAN may reserve the radio resource for the mobile station, and then reply to the RRC CONNECTION SETUP message to the mobile station through the transfer access channel, the message includes The setting information of the radio resource allocated to the mobile station, for example, the scrambling code used by the mobile station in the uplink direction. In response to the connection establishment of the RRC connection, the mobile station performs the synchronization procedure A to establish at least the downlink and uplink dedicated physical channels corresponding to the configured radio resources, and then replies to the RRC connection through the transfer access channel or the dedicated channel. The RRC CONNECTION SETUP COMPLETE message is sent to the UTRAN to inform the mobile station that the radio resource has been acknowledged. Once the UTRAN successfully receives the connection establishment completion message of the radio resource control, the connection establishment procedure is completed. The mobile station can then proceed to the specific procedure that initially triggers the connection establishment procedure. For example, if the establishment of the connection establishment procedure is "registration", the mobile station can continue to register with the UTRAN; if the establishment of the connection establishment procedure is "location update", the mobile station can continue to update its location to the UTRAN. News. It should be noted that in the connection establishment procedure, when the mobile station transmits the connection request message of the radio resource control, the radio resource configuration is preferentially assigned to the transfer access channel, and when the mobile station receives the radio resource control. When the connection establishes a message, the RF resource configuration is preferentially assigned to the dedicated channel, thus ensuring that the connection establishment procedure is not associated with specific operations of different service networks (eg, paging operations, measurement operations, and Interrupted by cell scan job, etc.). After that, when the mobile station transmits the connection establishment information of the radio resource control, it shoots The frequency resource configuration is preferentially assigned to specific jobs associated with different service networks (eg, paging jobs, measurement jobs, and cell scan jobs, etc.).

Figure 13 is a diagram showing the channel scheduling of a mobile station that is monitoring a 2G paging channel to perform a 3G connection establishment procedure according to an embodiment of the present invention. The mobile station (e.g., mobile station 200, 300, or 400) described in this embodiment can support simultaneous communication with GSM/GPRS/EDGE and UMTS systems. In particular, the mobile station uses a first subscriber identity card (labeled SIM-Y in Figure 13) to correlate to the GSM/GPRS/EDGE system to monitor the 2G paging channel and uses the second subscriber identity card (in Figure 13). The link labeled SIM-X) is associated with the UMTS system to perform the 3G connection establishment procedure. Specifically, the mobile station needs to continuously monitor the 2G paging channel to receive paging messages from the GSM/GPRS/EDGE system. The mobile station may need to listen to the Common Control Channel (CCCH) during each paging period of the discontinuous reception period to receive the paging message. As shown in FIG. 13, the radio resource configuration is preferentially assigned to the 2G paging channel for each paging period before the 3G connection establishment procedure is performed. When receiving the paging message, the mobile station will determine whether the paging message is for it. If so, the mobile station can enter the 3G idle mode for the UMTS system to receive the called call from the GSM/GPRS/EDGE system. Conversely, if the paging message is not directed to it, the mobile station can enter the 2G idle mode for the GSM/GPRS/EDGE system to wait for the next paging period, at this time, whether it is associated with the GSM/GPRS/EDGE system or the UMTS system. RF resource configuration can be obtained for any operation. However, in the 3G connection establishment procedure, when the mobile station transmits the RRC connection request message and waits for the connection of the RRC connection to establish a message, The frequency resource configuration is preferentially assigned to the 3G forwarding access channel; when the mobile station receives the connection establishment information of the radio resource control, the radio resource configuration is preferentially assigned to the 3G dedicated channel. In other words, the 3G connection establishment procedure can be interrupted by the 2G paging operation. After the 3G connection establishment procedure is completed (that is, after the connection establishment completion message of the radio resource control is transmitted), the radio resource configuration can be preferentially assigned to the 2G paging channel.

Figure 14 is a diagram showing an example of a Hard HandOver (HHO) procedure performed by a mobile station associated with a UMTS system. In this embodiment, the mobile station is first connected to the UMTS system via the source radio network controller and is in 3G connection mode. When the source radio network controller decides to reset the function of the serving radio network controller to the target radio network controller under the same SGSN (ie, handing over the mobile station from the source radio network controller to the target radio) In the case of the network controller, a handover request (HANDOVER REQUIRED) message is sent to the SGSN to request the handover of the mobile station. In response to the handover request message, the SGSN sends a Handover Request (HANDOVER REQUEST) message to the target radio network controller to request that resources be reserved for the mobile station. After the resource reservation is completed, the target radio network controller replies with a handover request confirmation (HANDOVER REQUEST ACKNOWLEDGE) message to the SGSN to inform the confirmation handover request message. Upon receiving the handover request acknowledgement message, the SGSN transmits a handover command (HANDOVER COMMAND) message to the source radio network controller to inform the handover that the handover preparation is completed. The source radio network controller then transmits a hard handoff command to the mobile station, the hard handoff command including the setup information needed at the target radio network controller. Specifically, the hard handover command can be heavy for the physical channel. PHYSICAL CHANNEL RECONFIGURATION message, RADIO BEARER RECONFIGURATION message, RADIO BEARER SETUP message, RADIO BEARER RELEASE message, or transmission channel reset (TRANSPORT CHANNEL RECONFIGURATION) )message. Taking the physical channel reset message as an example, the message may include a scrambling code required for the radio link of the target radio network controller, and a new UTRAN radio network temporary identifier for the handover (UTRAN Radio Network) Temporary Identifier, U-RNTI). The mobile station then uses the information contained in the hard handover command to change the settings of the wireless link to the target radio network controller and then transmits a hard handover response to the target radio network controller upon completion of the change to indicate Confirm the setting information contained in the hard delivery command. Specifically, the hard handover response may be a PHYSICAL CHANNEL RECONFIGURATION COMPLETE message, a RADIO BEARER RECONFIGURATION COMPLETE message, a RADIO BEARER SETUP COMPLETE message, The RADIO BEARER RELEASE COMPLETE message or the TRANS CHANNEL RECONFIGURATION COMPLETE message. It should be noted that the present invention can ensure that the hard handover procedure is not associated with different service networks during the period from the mobile station receiving the hard handover command from the UMTS system to the mobile station transmitting the hard handover response to the UMTS system. The specific jobs (for example, paging jobs, measurement jobs, and cell scan jobs, etc.) are interrupted. After receiving Upon a hard handover response, the target radio network controller then transmits a Handover Complete (HANDOVER COMPLETE) message to the SGSN. In response to the handover completion message, the SGSN transmits an Iu Release Command (IU RELEASE COMMAND) message to the serving radio network controller to request the serving radio network controller to release the Iu connection and the associated radio resources of the Iu connection.

Figure 15 is a diagram showing channel scheduling for a mobile station that is monitoring a 2G paging channel to perform a 3G hard handover procedure according to an embodiment of the invention. The mobile station (e.g., mobile station 200, 300, or 400) described in this embodiment can support simultaneous communication with GSM/GPRS/EDGE and UMTS systems. In particular, the mobile station uses a first subscriber identity card (labeled SIM-Y in Figure 15) associated with the GSM/GPRS/EDGE system to monitor the 2G paging channel and uses a second subscriber identity card (in Figure 15). Linked to SIM-X) is associated with the UMTS system to perform a 3G hard handover procedure. The mobile station needs to continuously monitor the 2G paging channel to receive paging messages from the GSM/GPRS/EDGE system. Specifically, the mobile station may need to listen to the general control channel to receive paging messages during the paging period of each discontinuous reception cycle. Before performing the 3G hard handover procedure, the mobile station connects to the UMTS system by performing a connection establishment procedure. For the detailed description of the channel scheduling operation of the connection establishment procedure, refer to the embodiment shown in FIG. 13 , and therefore, the details are not described herein. However, unlike the embodiment of FIG. 13 , the action in this embodiment is described. The station is in the cell transfer access channel mode and the 3G dedicated channel does not need to be specially protected in the connection establishment procedure. As shown in Figure 15, after the connection establishment procedure is completed and before the 3G hard handover procedure is performed, the radio resource configuration is preferentially assigned to the 2G paging pass for each paging period. Road. When receiving the paging message, the mobile station will determine whether the paging message is for it. If so, the mobile station can enter the 3G idle mode for the UMTS system to receive the called call from the GSM/GPRS/EDGE system. Conversely, if the paging message is not directed to it, the mobile station can enter the 2G idle mode for the GSM/GPRS/EDGE system to wait for the next paging period, at this time, whether it is associated with the GSM/GPRS/EDGE system or the UMTS system. RF resource configuration can be obtained for any operation. Then, when the mobile station receives a hard handover command from the UMTS system (ie, to inform the start of the hard handover procedure), the radio resource configuration is preferentially assigned to the 3G dedicated channel until the mobile station transmits the hard Hand over the response to the UMTS system. In other words, the 3G hard handover procedure can be interrupted by 2G paging. Once the hard handover response is transmitted to the UMTS system, the RF resource configuration can be preferentially assigned to the 2G paging channel.

Figure 16 is a schematic diagram of a software architecture of a mobile station according to an embodiment of the invention. Examples of the software architecture include protocol stack processing modules 1610 and 1620, and arbitration module 1630. The protocol stack processing module 1610, when executed by the processing unit or the Baseband MCU, is configured to communicate with the first service network (eg, the service network 120) using the first subscriber identity card (eg, the subscriber identity card 10); The protocol stack processing module 1620, when executed by the processing unit or the Baseband MCU, is configured to communicate with the second service network (eg, the service network 130) using the second subscriber identity card (eg, the subscriber identity card 20). . Since the mobile station is only configured with a single radio frequency module, the protocol stack processing modules 1610 and 1620 can request the control of the radio frequency module for wireless communication at the same time, so the arbitration module 1630 is used for the protocol stack processing. The modules 1610 and 1620 perform scheduling of radio frequency resource configuration.

FIG. 17 is a flow chart of a method for coordinating the operations of the stack processing modules 1610 and 1620 by the arbitration module 1630 according to an embodiment of the invention. First, the protocol stack processing modules 1610 and 1620 are in idle mode, and each can request the arbitration module 1630 to obtain the radio resource configuration required for communication with different service networks. At the beginning of the communication operation coordination method, the arbitration module 1630, upon receiving one of the agreement stack processing modules 1610 and 1620, requests to configure a specific channel (step S1701), determines whether there is currently available radio resource configuration (step S1702). If yes, the arbitration module 1630 grants the request and assigns the current radio resource configuration to the specific channel (step S1703), and then notifies the one of the agreed stack processing modules 1610 and 1620 that the radio resource configuration is no longer needed. The current RF resource configuration is retrieved (step S1704). Continuing to step S1702, conversely, if the current radio frequency resource configuration has been configured to another channel used by the other of the protocol stack processing modules 1610 and 1620 in executing a particular job/program or service, the arbitration module 1630 is based on The request and channel priority list determines whether the above specific job/program or service can be interrupted (step S1705). Specifically, the arbitration module 1630 may first determine whether the request indicates that the particular channel used is for a privileged program, and if so, whether the particular channel of the request has a higher priority than the other channel. If the particular channel of the request has a higher priority, then the particular job/program or service is considered to be interruptible, and then the arbitration module 1630 requests that the other of the stack processing modules 1610 and 1620 be suspended. The wireless operation performed by the other channel described above (step S1706). When receiving a response indicating that the current RF resource configuration has been released The arbitration module 1630 then grants the request and assigns the current radio resource configuration to the particular channel (step S1707). Then, when one of the agreed stack processing modules 1610 and 1620 notifies that the radio resource configuration is no longer needed, the arbitration module 1630 requests the other of the stack processing modules 1610 and 1620 to use the current radio resource configuration. The suspended wireless job is continued (step S1708). Next, in step S1705, if the specific job/program or service cannot be interrupted, the arbitration module 1630 rejects the request (step S1709).

In an embodiment, a privileged program list may be used to indicate procedures for possessing privileges, including: paging operations associated with GSM/GPRS/EDGE systems, packet access procedures, cell reselection procedures within the same radio access technology, and different wireless a cell reselection procedure between access technologies, a cell change command procedure, a packet cell change command procedure, a blind packet cell change command procedure, or a packet exchange handover procedure, or a paging operation associated with a UMTS system, a connection establishment procedure, or Hard handover procedure. Correspondingly, the channel priority list can be used to indicate the order of priority of the channels that need to be protected in the above-mentioned privileged program. Specifically, the 2G access promise channel, the broadcast control channel, the frequency correction channel, the synchronization channel, and the packet data channel used in the privileged program have higher priority than the 3G paging channel/paging indication channel; The 3G transfer access channel in the privileged program has a higher priority than the dedicated channel than the 2G paging channel; instead of the 3G transfer access channel and the dedicated channel for the privileged program, the 2G paging channel is compared to the 2G paging channel. Has a lower priority; the 2G access promise channel, the broadcast control channel, the frequency correction channel, the sync channel, and the packet data channel that are not used for the privileged program are lower than the 3G paging channel/paging indication channel. Priority.

It should be noted that, in the software architecture shown in FIG. 16, the protocol stack processing modules 1610 and 1620 may include multiple protocol layers (not shown), and the foregoing privileges are implemented in order to implement the channel protection described in the present invention. The information of the program list and the channel priority list can be provided by the upper layer to the first layer of the agreement layer (for example, provided by the RRC layer to the first layer).

Figures 18A and 18B show a sequence of messages that the arbitration module 1630 and the protocol stack processing modules 1610 and 1620 communicate with each other in the embodiment of Figure 7. In this embodiment, the protocol stack processing module 1610 communicates with the GPRS/EDGE system using a first subscriber identity card to perform a packet access procedure, and the protocol stack processing module 1620 performs a second subscriber identity card with the UMTS system. communication. In particular, the protocol stack processing module 1620 is in the 3G idle mode, and when in the 3G idle mode, the protocol stack processing module 1620 needs to continuously perform the paging operation to listen to the 3G paging channel to receive the paging message from the UMTS system. Specifically, the protocol stack processing module 1620 needs to listen to the paging indication channel or the paging channel during the paging period of each discontinuous reception period. For each paging period, the protocol stack processing module 1620 requests the arbitration module 1630 to obtain the radio resource configuration for the paging operation (step S1801). Since there is currently available radio resource configuration, the arbitration module 1630 decides to present the current The radio resource configuration is assigned to the paging channel of 3G (step S1802). Then, the arbitration module 1630 grants the request of the agreement stack processing module 1620 (step S1803). Because the request is granted, the protocol stack processing module 1620 accesses the unique radio frequency module to listen to the 3G paging channel (step S1804). After that, since no transmission was received during the current paging period The call message or the received paging message is not for the mobile station, so the agreement stack processing module 1620 notifies the arbitration module 1630 that it is no longer necessary to access the unique radio frequency module at the end of the paging period (step S1805). Upon receipt of the notification from the protocol stack processing module 1620, the arbitration module 1630 retrieves the current RF resource configuration assigned to the 3G paging channel (step S1806). Then, when the protocol stack processing module 1610 needs to execute the packet access procedure, the arbitration module 1630 is requested to assign the radio resource configuration to the access promise channel during the execution of the packet access procedure (step S1807), since there is currently The available radio resource configuration, so the arbitration module 1630 decides to assign the current radio resource configuration to the 2G access entitlement channel (step S1808). The arbitration module 1630 then grants a request to the agreement stack processing module 1610 (step S1809). Because the request is granted, the agreement stack processing module 1610 accesses the unique RF module to monitor the 2G access promise channel (step S1810). As shown in FIG. 7, for the next two paging periods, the protocol stack processing module 1620 requests the arbitration module 1630 to obtain the radio resource configuration for the paging operation (steps S1811 and S1813), however, due to the current radio frequency. The resource configuration has been assigned to the protocol stack processing module 1610 to monitor the 2G access promise channel, so the arbitration module 1630 rejects the request from the protocol stack processing module 1620 (steps S1812 and S1814). Then, when the packet access procedure ends, the protocol stack processing module 1610 notifies the arbitration module 1630 that it no longer needs to access the unique radio frequency module (step S1815). Upon receipt of the notification from the protocol stack processing module 1610, the arbitration module 1630 retrieves the current RF resource configuration assigned to the 2G access promise channel (step S1816). After that, when receiving the agreement stack processing module 1620, the RF resource for the paging operation is received. When the source is configured (step S1817), the arbitration module 1630 decides to assign the current radio resource configuration to the 3G paging channel (step S1818). The arbitration module 1630 then grants a request to the agreement stack processing module 1620 (step S1819). Next, steps S1820 to S1822 are similar to steps S1804 to S1806. First, the protocol stack processing module 1620 first accesses the unique radio frequency module to listen to the 3G paging channel (step S1820), and because there is no current paging period. Receiving any paging message, or receiving the paging message is not for the mobile station, so the agreement stack processing module 1620 notifies the arbitration module 1630 that it is no longer necessary to access the unique radio frequency module at the end of the paging period (step S1821), then the arbitration module 1630, upon receiving the notification from the protocol stack processing module 1620, reclaims the current radio resource configuration assigned to the 3G paging channel (step S1822).

19A and 19B are message sequence diagrams showing the arbitration module 1630 and the protocol stack processing modules 1610 and 1620 communicating with each other in the embodiment of FIG. In this embodiment, the protocol stack processing module 1610 communicates with the GPRS/EDGE system using a first subscriber identity card to perform a packet access procedure, and the protocol stack processing module 1620 performs a second subscriber identity card with the UMTS system. communication. In particular, the protocol stack processing module 1610 is in a 2G packet transmission mode for packet switched data services, and the protocol stack processing module 1620 is in a 3G idle mode. The protocol stack processing module 1610 requests the arbitration module 1630 to assign the radio resource configuration to the packet data channel for the packet exchange data service (step S1901). Module 1630 decides to assign the current RF resource configuration The packet data channel of 2G is given (step S1902). Then, the arbitration module 1630 grants a request to the agreement stack processing module 1610 (step S1903). Because the request is granted, the protocol stack processing module 1610 accesses the unique radio frequency module to perform the packet exchange data service through the 2G packet data channel (step S1904). Later, when the protocol stack processing module 1620 needs to perform a paging operation to listen to the 3G paging channel to receive the paging message from the UMTS system, the arbitration module 1630 is requested to obtain the radio resource configuration for the paging operation (step S1905). Since the 3G paging channel has a higher priority than the 2G packet data channel, the arbitration module 1630 decides to assign the current RF resource configuration to the 3G paging channel. Specifically, the arbitration module 1630 first requests the agreement stack processing module 1610 to suspend the ongoing packet exchange data service (step S1906). Upon receiving the request, the agreement stack processing module 1610 suspends the ongoing packet exchange data service and stops accessing the unique radio frequency module (step S1907), and then transmits a response to the arbitration module 1630 to instruct the packet exchange data. The service has been suspended (step S1908). Then, the arbitration module 1630, when receiving the response of the protocol stack processing module 1610, assigns the current radio frequency resource configuration to the 3G paging channel (step S1909), and then grants the request of the agreement stack processing module 1620 (step S1910). ). Because the request is granted, the agreement stack processing module 1620 accesses the unique radio frequency module to listen to the 3G paging channel (step S1911). Thereafter, since no paging message is received in the current paging period, or the received paging message is not for the mobile station, the agreement stack processing module 1620 notifies the arbitration module 1630 that the paging module 1630 is no longer present at the end of the paging period. A unique RF module needs to be accessed (step S1912). Upon receiving the agreement stack processing module 1620 At the time of the notification, the arbitration module 1630 then requests the agreement stack processing module 1610 to continue the suspended packet exchange data service (step S1913). The protocol stack processing module 1610 then accesses the unique radio frequency module to continue the suspended packet exchange data service (step S1914).

Then, in the process of the packet exchange data service, when it is necessary to perform a cell reselection procedure (including: a cell reselection procedure in the same radio access technology, and a cell reselection procedure between different radio access technologies), the cell is changed. The protocol stack processing module 1610 requests the arbitration module 1630 to assign the radio resource configuration to the 2G broadcast control channel when the command program or the packet cell change command program receives the system information through the 2G broadcast control channel and/or measures the surrounding cell ( Step S1915), since the 2G broadcast control channel used in the above procedure has a higher priority than the 2G packet data channel, the arbitration module 1630 decides to assign the current RF resource configuration to the 2G broadcast control channel ( Step S1916). Then, the arbitration module 1630 grants the request of the agreement stack processing module 1610 (step S1917). Because the request is granted, the agreement stack processing module 1610 receives and transmits the system information of the GPRS/EDGE system through the 2G broadcast control channel or measures the surrounding cell by sending and receiving part of the data associated with the packet exchange data service. The job between the packet exchange data service and the system information reception/surrounding cell measurement is coordinated (step S1918). In the process of the foregoing procedure (the cell reselection procedure, the cell change command procedure, and the packet cell change command procedure), the arbitration module 1630 receives the RF resource configuration for the paging operation by the agreement stack processing module 1620 (step S1919). And S1921), because the 2G broadcast control channel has a higher priority than the 3G paging channel, the request is rejected (step S1920 and S1922). When the above procedure (the cell reselection procedure, the cell change command procedure, the packet cell change command procedure) ends, the protocol stack processing module 1610 notifies the arbitration module 1630 that the broadcast control channel of 2G is no longer needed (step S1923). . Upon receiving the notification from the protocol stack processing module 1610, the arbitration module 1630 knows that the protocol stack processing module 1610 now only needs to perform the packet exchange data service, and the radio resource configuration only needs to be assigned to the 2G packet data channel. Therefore, the arbitration module 1630 can then grant the agreement stack processing module 1620 to obtain the request for the radio resource configuration for the paging operation.

It should be noted that those skilled in the art will be able to clarify how the stacking processing modules 1610 and 1620 are coordinated by the arbitration module 1630 according to the embodiments shown in Figures 18A, 18B, 19A, and 19B. Blind packet cell change command procedure, blind packet exchange handover procedure, cell change command procedure, or radio resource configuration of 2G frequency correction channel or synchronization channel in cell reselection procedure between different radio access technologies, and exchange in packet exchange The RF resource configuration of the 2G packet data channel in the delivery procedure is not described here.

20A and 20B are message sequence diagrams showing the arbitration module 1630 and the protocol stack processing modules 1610 and 1620 communicating with each other in the embodiment of FIG. In this embodiment, the protocol stack processing module 1610 communicates with the UMTS system using a first subscriber identity card to perform a connection setup procedure, and the protocol stack processing module 1620 uses a second subscriber identity card with GSM/GPRS/EDGE. The system communicates. In particular, the protocol stack processing module 1610 is in the 3G idle mode, and then performs the connection establishment procedure and enters the cell transfer access channel mode/cell dedicated channel mode, and the agreement The stack processing module 1620 is in the 2G idle mode. When in the 2G idle mode, the protocol stack processing module 1620 needs to continuously perform paging operations to listen to the 2G paging channel to receive paging messages from the GSM/GPRS/EDGE system. Specifically, the protocol stack processing module 1620 needs to listen to the paging channel during the paging period of each discontinuous reception cycle. Before the protocol stack processing module 1610 needs to perform the connection establishment procedure, the agreement stack processing module 1620 requests the arbitration module 1630 to obtain the radio resource configuration for the paging operation (step S2001), since there is currently available radio resource configuration, The arbitration module 1630 decides to assign the current radio resource configuration to the 2G paging channel (step S2002). The arbitration module 1630 then grants a request to the agreement stack processing module 1620 (step S2003). Because the request is granted, the agreement stack processing module 1620 accesses the unique radio frequency module to listen to the 2G paging channel (step S2004). Thereafter, since no paging message is received in the current paging period, or the received paging message is not for the mobile station, the agreement stack processing module 1620 notifies the arbitration module 1630 that the paging module 1630 is no longer present at the end of the paging period. A unique RF module needs to be accessed (step S2005). Upon receipt of the notification from the protocol stack processing module 1620, the arbitration module 1630 retrieves the current RF resource configuration assigned to the 2G paging channel (step S2006).

Later, when the protocol stack processing module 1610 needs to perform the connection establishment procedure, the arbitration module 1630 is requested to assign the radio resource configuration to the 3G transfer access channel and the dedicated channel (step S2007), since the RF is currently available. The resource configuration, so the arbitration module 1630 decides to assign the current radio resource configuration to the 3G forwarding access channel and the dedicated channel (step S2008). Then, the arbitration module 1630 grants the agreement stack processing module The request of 1610 (step S2009). Because the request is granted, the protocol stack processing module 1610 accesses the unique radio frequency module to transmit the RRC connection request message to the UMTS system through the 3G random access channel and monitors the 3G transfer access channel to receive the radio resource control. The connection establishes a message (step S2010). In an embodiment, the protocol stack processing module 1610 may transmit a physical channel priority adjustment request (CPHY_CHANNEL_PRIORITY_ADJUSTMENT_REQ) message to the unique radio frequency module to request to reserve the 3G transfer access channel. In the process of the connection establishment process, when the protocol stack processing module 1620 receives the RF resource configuration for the paging operation (step S2011), the 3G transfer access channel has a higher priority than the 2G paging channel. Level, so the arbitration module 1630 rejects the request (step S2012). Then, when receiving the connection establishment information of the radio resource control from the UMTS system through the 3G transfer access channel, the protocol stack processing module 1610 accesses the unique radio frequency module to reserve the 3G dedicated channel for entering the cell dedicated channel mode. The wireless setting (that is, for executing the A synchronization procedure described above) (step S2013). After the wireless setting is completed, the protocol stack processing module 1610 transmits the connection establishment completion message of the RRC control to the UMTS system through the 3G dedicated channel, and notifies the arbitration module 1630 that the connection establishment procedure has ended (step S2014). In an embodiment, the wireless setting may be completed upon receiving a physical downlink initial synchronization indication (CPHY_DL_INIT_SYNC_IND) message from the unique radio frequency module. When receiving the notification of the agreement stack processing module 1610, the arbitration module 1630 sets the current radio resource configuration assigned to the 3G forwarding access channel and the dedicated channel to be reassignable (ie, the agreement stack processing module 1610) The ongoing wireless job can be interrupted (step S2015). Thereafter, when the protocol stack processing module 1620 needs to perform a paging operation to listen to the 2G paging channel to receive the paging message from the GSM/GPRS/EDGE system, the arbitration module 1630 is requested to obtain the radio resource configuration for the paging operation (steps). S2016), since the 3G transfer access channel not used in the connection establishment procedure has a lower priority than the dedicated channel than the 2G paging channel, the arbitration module 1630 decides to assign the current RF resource configuration to the 2G. Paging channel. Specifically, the arbitration module 1630 first requests the protocol stack processing module 1610 to suspend any wireless operation through the 3G transfer access channel and the dedicated channel (step S2017). When the request is received, since the protocol stack processing module 1610 does not currently perform any wireless operation, a response is immediately transmitted to the arbitration module 1630 to indicate that the request has been completed (step S2018). Then, when receiving the response of the agreement stack processing module 1610, the arbitration module 1630 assigns the current radio frequency resource configuration to the 2G paging channel (step S2019), and then grants the request of the agreement stack processing module 1620 (step S2020). ). Because the request is granted, the protocol stack processing module 1620 accesses the unique radio frequency module to listen to the 2G paging channel (step S2021). Thereafter, since no paging message is received in the current paging period, or the received paging message is not for the mobile station, the agreement stack processing module 1620 notifies the arbitration module 1630 that the paging module 1630 is no longer present at the end of the paging period. It is necessary to access a unique radio frequency module (step S2022). Upon receiving the notification from the agreement stack processing module 1620, the arbitration module 1630 then requests the protocol stack processing module 1610 to continue the suspended wireless job (step S2023).

Figures 21A-21C show the arbitration module 1630 and the agreement stack The message sequence diagrams of the modules 1610 and 1620 communicate with each other in the embodiment of FIG. In this embodiment, the protocol stack processing module 1610 communicates with the UMTS system using a first subscriber identity card to perform a connection setup procedure, and the protocol stack processing module 1620 uses a second subscriber identity card with GSM/GPRS/EDGE. The system communicates. In particular, the protocol stack processing module 1610 is in the 3G idle mode, and then performs a connection establishment procedure to enter the cell transfer access channel mode, and then performs a hard handover procedure to enter the cell dedicated channel mode; and the protocol stack processing module The 1620 is in 2G idle mode. When in the 2G idle mode, the protocol stack processing module 1620 needs to continuously perform paging operations to listen to the 2G paging channel to receive paging messages from the GSM/GPRS/EDGE system. Specifically, the protocol stack processing module 1620 needs to listen to the paging channel during the paging period of each discontinuous reception cycle. Before the protocol stack processing module 1610 needs to perform the connection establishment procedure, the agreement stack processing module 1620 requests the arbitration module 1630 to obtain the radio resource configuration for the paging operation (step S2101), because there is currently available radio resource configuration, The arbitration module 1630 decides to assign the current radio resource configuration to the 2G paging channel (step S2102). Then, the arbitration module 1630 grants the request of the agreement stack processing module 1620 (step S2103). Because the request is granted, the agreement stack processing module 1620 accesses the unique radio frequency module to listen to the 2G paging channel (step S2104). Thereafter, since no paging message is received in the current paging period, or the received paging message is not for the mobile station, the agreement stack processing module 1620 notifies the arbitration module 1630 that the paging module 1630 is no longer present at the end of the paging period. A unique RF module needs to be accessed (step S2105). Arbitration upon receipt of notification from the agreement stack processing module 1620 The module 1630 reclaims the current radio resource configuration assigned to the 2G paging channel (step S2106).

Later, when the protocol stack processing module 1610 needs to perform the connection establishment procedure, the arbitration module 1630 is requested to assign the radio resource configuration to the 3G transfer access channel (step S2107). Since the available radio resource configuration is available, Therefore, the arbitration module 1630 decides to assign the current radio frequency resource configuration to the 3G transfer access channel (step S2108). Then, the arbitration module 1630 grants the request of the agreement stack processing module 1610 (step S2109). Because the request is granted, the protocol stack processing module 1610 accesses the unique radio frequency module to transmit the RRC connection request message to the UMTS system through the 3G random access channel and monitors the 3G transfer access channel to receive the radio resource control. The connection establishes a message (step S2110). In one embodiment, the protocol stack processing module 1610 can transmit a physical channel priority adjustment request message to a unique radio frequency module to request to reserve a 3G transfer access channel. In the process of the connection establishment process, when the protocol stack processing module 1620 receives the RF resource configuration for the paging operation (step S2111), the 3G transfer access channel has a higher priority than the 2G paging channel. Level, so the arbitration module 1630 rejects the request (step S2112). Then, when receiving the connection establishment information of the radio resource control from the UMTS system through the 3G transfer access channel, the protocol stack processing module 1610 accesses the unique radio frequency module for wireless setting (ie, performing the above A synchronization). The program, wherein the wireless setting further indicates that the protocol stack processing module 1610 remains in the cell transfer access channel mode (step S2113). After the wireless setting is completed, the protocol stack processing module 1610 transmits the connection establishment completion message of the radio resource control to the UMTS through the 3G transfer access channel. The system notifies the arbitration module 1630 that the connection establishment procedure has ended (step S2114). In an embodiment, the wireless setting may be completed when receiving a physical downlink initial synchronization indication message from a unique radio frequency module. Upon receiving the notification from the protocol stack processing module 1610, the arbitration module 1630 sets the current radio resource configuration assigned to the 3G forwarding access channel to be reassignable (ie, the protocol stack processing module 1610 is performing wireless). The job can be interrupted) (step S2115). Thereafter, when the protocol stack processing module 1620 needs to perform a paging operation to listen to the 2G paging channel to receive the paging message from the GSM/GPRS/EDGE system, the arbitration module 1630 is requested to obtain the radio resource configuration for the paging operation (steps). S2116), since the 3G transfer access channel not used in the connection establishment procedure has a lower priority than the 2G paging channel, the arbitration module 1630 decides to assign the current RF resource configuration to the 2G paging channel. . Specifically, the arbitration module 1630 first requests the protocol stack processing module 1610 to suspend any wireless service through the 3G transfer access channel (step S2117). When the request is received, since the protocol stack processing module 1610 does not currently perform any wireless operations, a response is immediately sent to the arbitration module 1630 to indicate that the request has been completed (step S2118). Then, when receiving the response of the agreement stack processing module 1610, the arbitration module 1630 assigns the current radio frequency resource configuration to the 2G paging channel (step S2119), and then grants the request of the agreement stack processing module 1620 (step S2120). ). Because the request is granted, the agreement stack processing module 1620 accesses the unique radio frequency module to listen to the 2G paging channel (step S2121). After that, since no paging message is received during the current paging period, or the paging message received is not for the mobile station, The protocol stack processing module 1620 notifies the arbitration module 1630 that it is no longer necessary to access the unique radio frequency module at the end of the paging period (step S2122). Upon receiving the notification from the protocol stack processing module 1620, the arbitration module 1630 then requests the protocol stack processing module 1610 to continue the interrupted wireless job (step S2123).

Then, when the agreement stack processing module 1610 needs to perform a hard handover procedure (ie, when receiving a hard handover command from the UMTS system, for example: physical channel reset message, wireless load reset message, wireless bearer setup) The message, the wireless carrier release message, or the transmission channel reset message) requests the arbitration module 1630 to assign the radio resource configuration to the dedicated channel of the 3G (step S2124), and the arbitration module 1630 also decides to assign the radio resource configuration to The dedicated channel of 3G (step S2125), so the request of the agreement stack processing module 1610 is granted (step S2126). Because the request is granted, the protocol stack processing module 1610 accesses the unique radio frequency module for wireless setting (ie, performing the A synchronization procedure described above), wherein the wireless setting also indicates that the protocol stack processing module 1610 enters the cell-specific channel. Mode (step S2127). After the wireless setting is completed, the protocol stack processing module 1610 transmits a hard handover response through the 3G dedicated channel (eg, physical channel reset completion message, wireless load reset completion message, wireless ride completion completion message, wireless ride release). The completion message, or the transmission channel reset completion message is sent to the UMTS system, and the arbitration module 1630 is notified that the hard handover procedure has ended (step S2128). In an embodiment, the wireless setting may be completed when receiving a physical downlink initial synchronization indication message from a unique radio frequency module. When receiving the notification from the protocol stack processing module 1610, the arbitration module 1630 will assign the current radio resource to the 3G dedicated channel. The configuration is set to be reassignable (ie, the wireless operation being performed by the protocol stack processing module 1610 is interruptible) (step S2129).

Figure 22 is a schematic diagram of a software architecture of a mobile station according to another embodiment of the present invention. An example of the software architecture includes protocol stack processing modules 2210 and 2220. The protocol stack processing module 2210 is configured to communicate with the first service network (eg, the service network 120) using the first subscriber identity card (eg, the subscriber identity card 10) when executed by the processing unit or the Baseband MCU; The protocol stack processing module 2220 is configured to communicate with the second service network (eg, the service network 130) using the second subscriber identity card (eg, the subscriber identity card 20) when executed by the processing unit or the Baseband MCU. . Unlike the software architecture shown in Figure 16, the protocol stack processing modules 2210 and 2220 communicate directly with each other to coordinate the respective operations to be performed. Specifically, when the protocol stack processing modules 2210 and 2220 request control of the unique radio frequency module for wireless communication at the same time, it indicates that a job conflict occurs, and then communicates with each other to determine the radio frequency resource configuration for the time period. Assigned to the protocol stack processing module 2210 or 2220.

FIG. 23 is a flow chart of a method for coordinating operations by the protocol stack processing modules 2210 and 2220 according to an embodiment of the invention. First, the protocol stack processing modules 2210 and 2220 are respectively associated with different service networks and are in idle mode, and can issue requests to each other to negotiate who can obtain the radio resource configuration for wireless operation. At the beginning of the communication operation coordination method, when one of the agreement stack processing modules 2210 and 2220 needs to communicate with the first service network, a request is sent to the other, wherein the request indicates the channel to be used. And the program or operation for the channel (step S2301), in an embodiment, if the wireless job to be performed is paging In the case of a job, the request may indicate that the channel to be used is a paging channel and the paging channel is used for paging. In another embodiment, if the wireless job to be performed is a packet access procedure, the request may indicate that the channel to be used is an access promise channel and the access promise channel is used for a packet access procedure. Upon receiving the request, the other of the protocol stack processing modules 2210 and 2220 may determine whether the request conflicts with the wireless operation being performed by the second service network (step S2302), and if so, further determine Whether or not the wireless job in progress itself can be interrupted (step S2303). Specifically, the other of the agreement stack processing modules 2210 and 2220 can first determine whether the channel indicated by the request is for a program having privileges, and if so, further determine that the channel indicated by the request is more recent than The channels used for ongoing wireless jobs have a higher priority. If the determination is yes, the channel used by the wireless job in progress can be regarded as interruptible, and then the other of the agreement stack processing modules 2210 and 2220 suspends the wireless job in progress (step S2304). Then, a response is sent to the other party to indicate that the request has been accepted (step S2305), so that one of the agreement stack processing modules 2210 and 2220 can obtain the current radio resource configuration to communicate with the first service network. Then, when one of the agreement stack processing modules 2210 and 2220 receives the RF resource configuration, the other one of the protocol stack processing modules 2210 and 2220 continues to perform the suspended wireless job (step S2306). ). In step S2303, if the wireless job in progress of the other of the contract stack processing modules 2210 and 2220 cannot be interrupted, a response is sent to the other party to indicate that the request has been rejected (step S2307). In step S2302, if the request does not cause a job conflict, the agreement stack The other of the processing modules 2210 and 2220 can issue a response to the other party to indicate that the request has been accepted (step S2308), and then notify the one of the agreement stack processing modules 2210 and 2220 that the RF resource is no longer needed. When configured, the current RF resource configuration is reclaimed (step S2309).

In an embodiment, a privileged program list may be used to indicate procedures for possessing privileges, including: paging operations associated with GSM/GPRS/EDGE systems, packet access procedures, cell reselection procedures within the same radio access technology, and different wireless a cell reselection procedure between access technologies, a cell change command procedure, a packet cell change command procedure, a blind packet cell change command procedure, or a packet exchange handover procedure, or a paging operation associated with a UMTS system, a connection establishment procedure, or Hard handover procedure. Correspondingly, the channel priority list can be used to indicate the order of priority of the channels that need to be protected in the above-mentioned privileged program. Specifically, the 2G access promise channel, the broadcast control channel, the frequency correction channel, the synchronization channel, and the packet data channel used in the privileged program have higher priority than the 3G paging channel/paging indication channel; The 3G transfer access channel in the privileged program has a higher priority than the dedicated channel than the 2G paging channel; instead of the 3G transfer access channel and the dedicated channel for the privileged program, the 2G paging channel is compared to the 2G paging channel. Has a lower priority; the 2G access promise channel, the broadcast control channel, the frequency correction channel, the sync channel, and the packet data channel that are not used for the privileged program are lower than the 3G paging channel/paging indication channel. priority.

It should be noted that, in the software architecture shown in FIG. 22, the protocol stack processing modules 2210 and 2220 may include multiple protocol layers (not shown), and the foregoing privileges are implemented in order to implement the channel protection described in the present invention. Program list and The information of the channel priority list can be provided by the upper layer protocol layer to the first layer agreement layer (for example, provided by the radio resource control layer to the first layer).

Figure 24 is a sequence diagram showing the communication between the protocol stack processing modules 2210 and 2220 in the embodiment of Figure 7. In this embodiment, the protocol stack processing module 2210 uses the first subscriber identity card to communicate with the GPRS/EDGE system to perform the packet access procedure, and the protocol stack processing module 2220 uses the second subscriber identity card to communicate with the UMTS system. communication. In particular, the protocol stack processing module 2220 is in the 3G idle mode, and when in the 3G idle mode, the protocol stack processing module 2220 needs to continuously perform the paging operation to listen to the 3G paging channel to receive the paging message from the UMTS system. For a paging period, the protocol stack processing module 2220 sends a request to the protocol stack processing module 2210, wherein the request indicates that the channel to be used is a 3G paging channel, and the channel is used for paging operations (step S2401), The protocol stack processing module 2210 does not need to execute the packet access procedure yet, so it is decided to accept the request (step S2402). Because the request is accepted, the protocol stack processing module 2220 accesses the unique radio frequency module to listen to the 3G paging channel (step S2403). Thereafter, since no paging message is received during the current paging period, or the received paging message is not for the mobile station, the protocol stack processing module 2220 stops accessing the unique radio frequency module at the end of the paging period. (Step S2404). Then, when the protocol stack processing module 2210 needs to execute the packet access procedure, a request is sent to the protocol stack processing module 2220, wherein the request indicates that the channel to be used is a 2G access promise channel, and the channel system For the packet access procedure (step S2405), since the protocol stack processing module 2220 does not currently need to execute any jobs or programs, It is decided to accept the request (step S2406). Because the request is accepted, the protocol stack processing module 2210 accesses the unique radio frequency module to monitor the 2G access promise channel (step S2407). As shown in FIG. 7, for the next two paging periods, the protocol stack processing module 2220 issues a request to the protocol stack processing module 2210 to obtain the radio resource configuration for the paging operation (steps S2408 and S2410), however, Since the current RF resource configuration has been assigned to the 2G access promise channel, and the 2G access promise channel for the packet access procedure has a higher priority than the 3G paging channel, the protocol stack processing module 2210 rejects The request of the agreement stack processing module 2220 (steps S2409 and S2411). Then, when the packet access procedure ends, the protocol stack processing module 2210 stops accessing the unique radio frequency module (step S2412). After receiving the RF resource configuration for the paging operation by the agreement stack processing module 2220 (step S2413), since the agreement stack processing module 2210 does not need to execute any job or program at present, it is decided to accept the request (step S2414). . Then, the agreement stack processing module 2220 accesses the unique radio frequency module to listen to the 3G paging channel (step S2415), and because no paging message is received in the current paging period, or the received paging message is not targeted The mobile station processing module 2220 stops accessing the unique radio frequency module at the end of the paging period (step S2416).

Figure 25 is a sequence diagram showing the communication of the protocol stack processing modules 2210 and 2220 to each other in the embodiment of Figure 8. In this embodiment, the protocol stack processing module 2210 uses the first subscriber identity card to communicate with the GPRS/EDGE system to perform the packet access procedure, and the protocol stack processing module 2220 uses the second subscriber identity card to communicate with the UMTS system. communication. particular Yes, the protocol stack processing module 2210 is in the 2G packet transmission mode for the packet exchange data service, and the protocol stack processing module 2220 is in the 3G idle mode. Because it is in the 2G packet transmission mode, the protocol stack processing module 2210 sends a request to the protocol stack processing module 2220, wherein the request indicates that the channel to be used is a 2G packet data channel, and the channel is used for packet exchange data service. (Step S2501), since the agreement stack processing module 2220 does not currently need to execute any job or program, it is decided to accept the request of the agreement stack processing module 2210 (step S2502). Because the request is accepted, the protocol stack processing module 2210 accesses the unique radio frequency module to perform the packet exchange data service through the 2G packet data channel (step S2503). Later, when the protocol stack processing module 2220 needs to perform a paging job to listen to the 3G paging channel to receive the paging message from the UMTS system, a request is sent to the protocol stack processing module 2210, wherein the request indicates the desired use. The channel is a 3G paging channel, and the channel is used for paging operations (step S2504). Since the 3G paging channel has a higher priority than the 2G packet data channel, the protocol stack processing module 2210 stops accessing. The unique radio frequency module exchanges the data exchange service in the ongoing packet (step S2505), and then accepts the request of the agreement stack processing module 2220 (step S2506). Because the request is accepted, the protocol stack processing module 2220 accesses the unique radio frequency module to listen to the 3G paging channel (step S2507). Thereafter, since no paging message is received during the current paging period, or the received paging message is not for the mobile station, the protocol stack processing module 2220 stops accessing the unique radio frequency module at the end of the paging period. (Step S2508), and then notify the agreement stack processing module 2210 that it is no longer needed to save Take a unique RF module (step S2509). Upon receipt of the notification from the protocol stack processing module 2220, the protocol stack processing module 2210 continues the suspended packet exchange data service (step S2510).

Then, in the process of the packet exchange data service, when it is necessary to perform a cell reselection procedure (including: a cell reselection procedure in the same radio access technology, and a cell reselection procedure between different radio access technologies), the cell is changed. When the command program, or the packet cell change command procedure, receives system information through the 2G broadcast control channel and/or measures the surrounding cell, the protocol stack processing module 2210 coordinates the packet exchange data service and the system information reception/surround cell measurement. The operation, in particular, because the 2G broadcast control channel used in the above procedure has a higher priority than the 2G packet data channel, the protocol stack processing module 2210 transmits the part associated with the packet exchange data service. The data is sent and received to receive system information of the GPRS/EDGE system or measure the surrounding cell through the 2G broadcast control channel (step S2511). In the process of the above procedure (the cell reselection procedure, the cell change command procedure, or the packet cell change command procedure), when the protocol stack processing module 2220 receives the radio resource configuration for the paging operation (steps S2512 and S2514) The protocol stack processing module 2210 rejects the request because the 2G broadcast control channel has a higher priority than the 3G paging channel (steps S2513 and S2515). When the above procedure (the cell reselection procedure, the cell change command procedure, or the packet cell change command procedure) ends, the protocol stack processing module 2210 stops transmitting and dispatching part of the data associated with the packet exchange data service to perform broadcast control through 2G. The channel receives system information of the GPRS/EDGE system or measures the surrounding cell (step S2516). Thereafter, the paging operation is received from the agreement stack processing module 2220. The request for the radio resource configuration used may interrupt the packet exchange data service performed by the protocol stack processing module 2210.

It should be noted that those skilled in the art can, based on the embodiments shown in FIG. 24 and FIG. 25, figure out how to coordinate the command in the blind packet cell by the protocol stack processing modules 2210 and 2220. Program, blind packet exchange handover procedure, cell change command procedure, or radio resource configuration for 2G frequency correction channel or synchronization channel in cell reselection procedure between different radio access technologies, and 2G in packet exchange handover procedure The radio resource configuration of the packet data channel is not described here.

Figures 26A and 26B show a sequence of messages that the protocol stack processing modules 2210 and 2220 communicate with each other in the embodiment of Figure 13. In this embodiment, the protocol stack processing module 2210 communicates with the UMTS system using the first subscriber identity card to perform a connection setup procedure, and the protocol stack processing module 2220 uses the second subscriber identity card with GSM/GPRS/EDGE. The system communicates. In particular, the protocol stack processing module 2210 is in the 3G idle mode, and then performs the connection establishment procedure and enters the cell transfer access channel mode/cell dedicated channel mode, and the protocol stack processing module 2220 is in the 2G idle mode. When in the 2G idle mode, the protocol stack processing module 2220 needs to continuously perform paging operations to listen to the 2G paging channel to receive paging messages from the GSM/GPRS/EDGE system. Specifically, the protocol stack processing module 2220 needs to listen to the paging channel during the paging period of each discontinuous reception cycle. Before the protocol stack processing module 2210 needs to perform the connection establishment procedure, the protocol stack processing module 2220 sends a request to the protocol stack processing module 2210, wherein the request indicates that the channel to be used is a 2G paging channel, and the channel Used for paging operations (steps) S2601), since the protocol stack processing module 2210 does not need to execute the packet access procedure yet, it is decided to accept the request (step S2602). Because the request is accepted, the protocol stack processing module 2220 accesses the unique radio frequency module to listen to the 2G paging channel (step S2603). Thereafter, since no paging message is received during the current paging period, or the received paging message is not for the mobile station, the protocol stack processing module 2220 stops accessing the unique radio frequency module at the end of the paging period. (Step S2604).

Later, when the protocol stack processing module 2210 needs to perform the connection establishment procedure, a request is sent to the protocol stack processing module 2220, wherein the request indicates that the channel to be used is a 3G transfer access channel and a dedicated channel, And the channel is used for the connection establishment procedure (step S2605). Since the protocol stack processing module 2220 does not need to execute the packet access procedure yet, it is decided to accept the request (step S2606). Because the request is accepted, the protocol stack processing module 2210 accesses the unique radio frequency module to transmit the connection request message of the radio resource control to the UMTS system through the 3G random access channel and monitors the 3G transfer access channel to receive the wireless. The resource control connection establishes a message (step S2607). In one embodiment, the protocol stack processing module 2210 can transmit a physical channel priority adjustment request message to a unique radio frequency module to request to reserve a 3G transfer access channel. In the process of the connection establishment process, when the protocol stack processing module 2220 receives the RF resource configuration for the paging operation (step S2608), the 3G transfer access channel used in the connection establishment procedure is compared to 2G. The paging channel has a higher priority, so the agreement stack processing module 2210 rejects the request (step S2609). Then, when received through the 3G transfer access channel When the wireless resource control connection from the UMTS system establishes a message, the protocol stack processing module 2210 accesses the unique radio frequency module to protect the 3G dedicated channel for entering the wireless setting of the cell dedicated channel mode (ie, for performing the above A synchronization procedure) (step S2610). After the wireless setting is completed, the protocol stack processing module 2210 transmits the connection establishment completion message of the radio resource control to the UMTS system through the 3G dedicated channel, and stops protecting the 3G dedicated channel from the specific operation of the protocol stack processing module 2220 (for example, : The paging job, the measurement job, the cell scan job, and the like are interrupted, and the connection establishment procedure is ended (step S2611). In an embodiment, the wireless setting may be completed when receiving a physical downlink initial synchronization indication message from a unique radio frequency module.

Thereafter, when the protocol stack processing module 2220 needs to perform a paging operation to listen to the 2G paging channel to receive the paging message from the GSM/GPRS/EDGE system, a request is sent to the protocol stack processing module 2210, wherein the request indicates the location The channel to be used is a 2G paging channel, and the channel is used for paging operation (step S2612), since the 3G transfer access channel not used in the connection establishment procedure is compared with the dedicated channel compared to the 2G paging channel. The priority is low, so the protocol stack processing module 2210 stops accessing the unique radio frequency module to suspend the wireless service through the 3G dedicated channel (step S2613), and then accepts the request of the agreement stack processing module 2220 (step S2614). Because the request is accepted, the protocol stack processing module 2220 accesses the unique radio frequency module to listen to the 2G paging channel (step S2615). Thereafter, since no paging message is received during the current paging period, or the received paging message is not for the mobile station, the protocol stack processing module 2220 stops at the end of the paging period. The unique RF module is accessed (step S2616), and then the protocol stack processing module 2210 is notified that the unique RF module does not need to be accessed (step S2617). Upon receiving the notification from the agreement stack processing module 2220, the agreement stack processing module 2210 continues the suspended wireless job (step S2618).

Figures 27A and 27B show a sequence of messages that the protocol stack processing modules 2210 and 2220 communicate with each other in the embodiment of Fig. 15. In this embodiment, the protocol stack processing module 2210 communicates with the UMTS system using the first subscriber identity card to perform a connection setup procedure, and the protocol stack processing module 2220 uses the second subscriber identity card with GSM/GPRS/EDGE. The system communicates. In particular, the protocol stack processing module 2210 is in the 3G idle mode, and then performs a connection establishment procedure to enter the cell transfer access channel mode, and then performs a hard handover procedure to enter the cell dedicated channel mode; and the protocol stack processing module The 2220 is in 2G idle mode. When in the 2G idle mode, the protocol stack processing module 2220 needs to continuously perform paging operations to listen to the 2G paging channel to receive paging messages from the GSM/GPRS/EDGE system. Specifically, the protocol stack processing module 2220 needs to listen to the paging channel during the paging period of each discontinuous reception cycle. Before the protocol stack processing module 2210 needs to perform the connection establishment procedure, the protocol stack processing module 2220 sends a request to the protocol stack processing module 2210, wherein the request indicates that the channel to be used is a 2G paging channel, and the channel For the paging operation (step S2701), since the protocol stack processing module 2210 does not need to execute the packet access procedure yet, it is decided to accept the request (step S2702). Because the request is accepted, the protocol stack processing module 2220 accesses the unique RF module to Listening to the 2G paging channel (step S2703). Thereafter, since no paging message is received during the current paging period, or the received paging message is not for the mobile station, the protocol stack processing module 2220 stops accessing the unique radio frequency module at the end of the paging period. (Step S2704).

Later, when the protocol stack processing module 2210 needs to perform the connection establishment procedure, a request is sent to the protocol stack processing module 2220, wherein the request indicates that the channel to be used is a 3G transfer access channel, and the channel It is used for the connection establishment procedure (step S2705). Since the protocol stack processing module 2220 does not currently need to execute the packet access procedure, it is decided to accept the request (step S2706). Because the request is accepted, the protocol stack processing module 2210 accesses the unique radio frequency module to transmit the connection request message of the radio resource control to the UMTS system through the 3G random access channel and monitors the 3G transfer access channel to receive the wireless. The resource control connection establishes a message (step S2707). In one embodiment, the protocol stack processing module 2210 can transmit a physical channel priority adjustment request message to a unique radio frequency module to request to reserve a 3G transfer access channel. In the process of the connection establishment process, when the protocol stack processing module 2220 receives the RF resource configuration for the paging operation (step S2708), the 3G transfer access channel used in the connection establishment procedure is compared to 2G. The paging channel has a higher priority, so the agreement stack processing module 2210 rejects the request (step S2709). Then, when receiving the connection establishment information of the radio resource control from the UMTS system through the 3G transfer access channel, the protocol stack processing module 2210 accesses the unique radio frequency module to continue to protect the 3G transfer access channel for entering the cell. The wireless setting of the access channel mode is transferred (that is, for executing the above-described A synchronization procedure) (step S2710). After the wireless setting is completed, The protocol stack processing module 2210 transmits the connection establishment completion message of the radio resource control to the UMTS system through the 3G dedicated channel, and stops protecting the specific operation of the 3G dedicated channel from being unassigned by the stack processing module 2220 (for example, paging operation, measurement operation) The cell scan job, etc. is interrupted, and the connection establishment procedure is ended (step S2711). In an embodiment, the wireless setting may be completed when receiving a physical downlink initial synchronization indication message from a unique radio frequency module.

Thereafter, when the protocol stack processing module 2220 needs to perform a paging operation to listen to the 2G paging channel to receive the paging message from the GSM/GPRS/EDGE system, a request is sent to the protocol stack processing module 2210, wherein the request indicates the location The channel to be used is a 2G paging channel, and the channel is used for paging operation (step S2712), since the 3G transfer access channel not used in the connection establishment procedure has a lower priority than the 2G paging channel. Therefore, the agreement stack processing module 2210 stops accessing the unique radio frequency module to suspend the wireless service through the 3G transfer access channel (step S2713), and then accepts the request of the agreement stack processing module 2220 (step S2714). Because the request is accepted, the protocol stack processing module 2220 accesses the unique radio frequency module to listen to the 2G paging channel (step S2715). Thereafter, since no paging message is received during the current paging period, or the received paging message is not for the mobile station, the protocol stack processing module 2220 stops accessing the unique radio frequency module at the end of the paging period. (Step S2716), then it is notified that the protocol stack processing module 2210 does not need to access the unique radio frequency module (step S2717). Upon receiving the notification from the agreement stack processing module 2220, the agreement stack processing module 2210 continues the suspended wireless job (step S2718).

Then, when the agreement stack processing module 2210 needs to perform a hard handover procedure (ie, when receiving a hard handover command from the UMTS system, for example: physical channel reset message, wireless load reset message, wireless ride setup) The message, the wireless carrier release message, or the transmission channel reset message) accesses the unique RF module to protect the 3G dedicated channel for entering the wireless setting of the cell dedicated channel mode (ie, for performing the above A synchronization procedure) The 3G dedicated channel is not interrupted by the specific operation (eg, paging operation, measurement job, cell scan job, etc.) of the agreement stack processing module 2220 (step S2719). During the process of the hard handover procedure, when the protocol stack processing module 2220 needs to perform a paging operation to listen to the 2G paging channel to receive the paging message from the GSM/GPRS/EDGE system, a request is sent to the protocol stack processing module. 2210, wherein the request indicates that the channel to be used is a 2G paging channel, and the channel is used for paging operation (step S2720), because the 3G dedicated channel used in the hard handover procedure is compared to the 2G paging channel. There is a higher priority, so the agreement stack processing module 2210 rejects the request (step S2721). Later, after the wireless setting of entering the cell-dedicated channel mode is completed, the protocol stack processing module 2210 transmits a hard handover response through the 3G dedicated channel (eg, physical channel reset completion message, wireless load reset completion message, wireless ride) The completion message, the wireless carrier release completion message, or the transmission channel reset completion message is sent to the UMTS system, and the protection of the 3G dedicated channel is not affected by the specific operation of the protocol stack processing module 2220 (eg, paging operation, measurement operation, The cell scan job or the like is interrupted, and the hard handover procedure is ended (step S2722). In an embodiment, when the entity downlink initial synchronization indication message from the unique radio frequency module is received, the indication is completed. Into this wireless setting.

Then, when the protocol stack processing module 2220 needs to perform a paging operation, a request is sent to the protocol stack processing module 2210, wherein the request indicates that the channel to be used is a 2G paging channel, and the channel is used for paging. The operation (step S2723), since the 3G dedicated channel not used in the hard handover procedure has a lower priority than the 2G paging channel, the protocol stack processing module 2210 stops accessing the unique RF module to suspend transmission through the 3G. The wireless operation by the dedicated channel (step S2724), and then accepts the request of the agreement stack processing module 2220 (step S2725). Because the request is accepted, the protocol stack processing module 2220 accesses the unique radio frequency module to listen to the 2G paging channel (step S2726). Thereafter, since no paging message is received during the current paging period, or the received paging message is not for the mobile station, the protocol stack processing module 2220 stops accessing the unique radio frequency module at the end of the paging period. (Step S2727), then it is notified that the protocol stack processing module 2210 does not need to access the unique radio frequency module (step S2728). Upon receiving the notification from the agreement stack processing module 2220, the agreement stack processing module 2210 continues the paused wireless job (step S2729).

In addition to the software architectures shown in Figures 16 and 22, the present invention is also applicable to a stand-alone software architecture in which there is no communication between the protocol stack processing modules and no arbitration modules. Further, a register can be maintained in the unique RF module, and when the protocol stack processing module needs to access the RF module, an attempt is made to write to the scratchpad if the register has been If it is written, the access to the protocol stack processing module is denied; otherwise, if the register is not written, the protocol stack is accepted. Access to the module. In one embodiment, the register is used to record information about whether the RF module is occupied, and to record which channel is used if the RF module is occupied. Or, each time a write occurs, if the scratchpad has been written and the radio frequency module is now occupied by a higher priority channel, the access stack processing module is denied access; When the scratchpad has been written and the RF module is now occupied by a lower priority channel, it is accepted by the protocol stack processing module. Those skilled in the art will be able to figure out how to be in the above-mentioned independent type according to the software architecture shown in Figures 16 and 22, and the embodiments described in Figures 17-19 and 23-27.
