Cross Reference with Related Applications

This invention claims the priority of Provisional Application Serial No. 60 / 584,376, entitled "METHOD AND APPARATUS FOR RADIO FREQUENCY BAND ASSIGNMENT IN A WIRELESS COMMUNICATIN SYSTEM", filed June 30, 2004, which is incorporated herein by reference. will be.

Field of invention

The present invention relates generally to cellular communication systems, and more particularly to cellular communication systems supporting multiple bands.

A mobile station (MS) operating in a cdma2000 communication system is included in a wireless infrastructure via a first radio frequency (RF) band, such as the 800 MHz (MHz) band for establishing a call. When attempting to send a call to the BS, the BS does not recognize the MS's RF capabilities. The listing of services subscribed to by the MS and the MS identifier (Mobile ID) such as the International Mobile Subscriber Identity (IMSI) associated with the MS as well as the capabilities of the MS such as the RF bands supported by the MS are typically wireless-based. Stored in the profile of the MS in a home location register (HLR) located elsewhere in the structure.

In response to receiving a call origination request from the MS, the BS determines whether the first RF band is congested, for example, if any traffic channels are available in the first RF band, at or near the maximum power load. Determine if it works or if Walsh codes are exhausted. When the first RF band is not congested, the BS assigns an available traffic channel to the MS. In parallel with the traffic channel assignment, the BS delivers an A1 message, typically an A1 CM service request message, to a mobile switching center (MSC) that services the MS's BS request authentication and verification. In response to receiving the originating request, if the profile has not already been stored in the Visitor Location Register (VLR) associated with the MSC, the MSC downloads the full profile of the MS from the HLR and stores the downloaded profile in the associated VLR. The MSC then verifies and authenticates the MS based on the downloaded profile and notifies the BS whether to proceed with the call or tear down.

When the first RF band is congested, the BS terminates the MS's access attempt and releases the call. In this example, the BS never communicates with the MSC. In addition, the process of contacting the BS with the MSC, waiting for the MSC to download the profile of the MS and notifying the BS to proceed with the call, consumes a considerable amount of time and results in an unacceptable call setup delay for system operators. . If the MS is a single-band MS, the user of the MS will only retry accessing the communication system at a later time. If the MS is a multi-band MS capable of operating in multiple RF bands, the MS may initiate an access attempt of the communication system over a second RF band, such as a 2.1 gigahertz (GHz) or 1.9 GHz band. However, multiband MSs must reopen access attempts in the second RF band, consuming time and embarrassing users of such MSs.

Therefore, a method and apparatus for determining RF band capabilities of an MS with minimal delay in an initial call origination attempt and re-directing the multi-band MS to a different RF band when the accessed RF band is congested need.

Determining radio frequency (RF) band capabilities of an originating mobile station (MS) with minimal delay and addressing the need for a method and apparatus for allocating MS to different RF bands without prior system capacity consumption and call setup delay To this end, a wireless communication system is provided comprising a mobile station in communication with an infrastructure supporting multiple radio frequency (RF) band classes. When the infrastructure receives a call origination request from a mobile station on a first radio frequency (RF) band of multiple RF bands, the infrastructure determines whether to attempt to assign the mobile station to an RF band other than the first RF band. In response to determining that the mobile station attempts to allocate it to an RF band other than the first RF band, the infrastructure retrieves the RF traffic channel decision-related data maintained by the infrastructure before performing additional call processing and Based on this RF traffic channel decision-related data, it is determined whether the inter-band direction can be changed. When the mobile station can be inter-band redirected, the infrastructure redirects the mobile station to a second RF band of multiple RF bands.

In general, embodiments of the present invention include a method of allocating an RF band to a mobile station when the mobile station is in the process of sending a call through an infrastructure supporting multiple radio frequency (RF) bands. The method includes receiving a call origination request from a mobile station on a first RF band of multiple bands and determining whether to attempt to allocate the mobile station to an RF band other than the first RF band. The method is responsive to determining to assign a mobile station to an RF band other than the first RF band, receiving radio frequency traffic channel determination-related data maintained by the infrastructure and the mobile station relating to radio frequency traffic channel determination. Determining whether the inter-band direction can be changed based on the data.

Another embodiment of the invention includes an apparatus for allocating an RF band to a mobile station when the mobile station is involved in the process of initiating connection with the infrastructure. The apparatus includes a base station that receives a call origination request by the mobile station over a first radio frequency (RF) band and determines whether to attempt to assign the mobile station to an RF band other than the first RF band in response to receiving the call origination request. do. In response to the determination to assign the mobile station to an RF band other than the first RF band, the base station requests the infrastructure-maintained RF traffic channel determination-related data associated with the mobile station and responds to the request to the infrastructure-maintained RF. Receive traffic channel determination-related data. Based on the RF traffic channel determination-related data, the base station determines whether the mobile station can be inter-band redirected and before the mobile station performs any other call processing in response to determining that the mobile station can be inter-band redirected. 2 Instructs to switch to RF band.

Another embodiment of the present invention includes a call controller for receiving a service request, determining whether the service request includes a request for infrastructure-maintained radio frequency traffic channel determination-related data associated with a mobile station, Retrieve only a portion of the profile of the mobile station (the portion includes radio frequency traffic channel determination-related data associated with the mobile station) in response to determining whether the request includes infrastructure-maintained radio frequency traffic channel determination-related data; Deliver the retrieved radio frequency traffic channel decision-related data to the base station before performing the additional call processing.

The invention can be explained in more detail with reference to FIGS. 1 to 2B. 1 is a block diagram of a wireless communication system 100 in accordance with an embodiment of the present invention. The communication system 100 includes at least one mobile station (MS) 102, which is not limited to a cellular telephone, a wireless telephone, or a wireless modem providing a wireless interface for data terminal equipment coupled to a modem. MS 102 may operate, ie, support, multiple radio frequency (RF) bands supported by infrastructure 104 of communication system 100. The MS's RF band capabilities are held in the MS's memory. The communication system 100 preferably comprises a wireless infrastructure 104 comprising at least one base station (BS) 106 coupled to a call controller 130, preferably a mobile switching center (MSC), via an A1 interface. It includes more. The call controller 130 is additionally coupled to a mobile location and provisioning database 140, such as a home location register (HLR).

BS 106 includes at least one base transceiver station (BTS) 110 coupled to a controller 120, typically a base station controller and / or a centralized base station controller (BSC / CBSC). The controller 120 controls and manages the operation of the BTS 110 and the communication of this BTS with any other BTSs of the BS 106. BS 106 is an MS 102 such as MS 102 located in a coverage area serviced by a BS for communication services in at least one RF band, for example, 800 MHz (MHz) band or 1.9 Ghz (GHz) band. It can serve as a mobile station. The call controller 130 routes authentication calls within the system 100 and provides authentication and verification support for BSs such as the BS 106 serviced by the call controller. Call controller 130 includes a local mobile location and authorization database 136, such as a visitor location register (VLR). However, in another embodiment of the present invention, the movement location and authorization database 136 may be external to the call controller 130 and may communicate with the call controller 130.

Each of the BTS 110, the controller 120, and the call controller 130 are each such as one or more microprocessors, microprocessors, digital signal processors (DSPs), combinations thereof, or other devices known to those skilled in the art. Processors 112, 122, and 132. Each of the BTS 110, controller 120, and call controller 130 stores programs and software, such as programs, applications, and operating protocols, executed by a processor, and stores MS, BS, Each one or more memory devices associated with each processor, such as random access memory (RAM), dynamic random access memory (DRAM), and / or read-only memory (ROM) or their equivalents that allow the function of a controller or call controller. And additionally include (114, 124, 124). Each of the one or more memory devices 124, 134 of the controller 120 and the call controller 130 additionally store information relating to the RF bands that may be supported by the infrastructure 104. Unless otherwise defined herein, the functions performed by each of the BTS 110, the controller 120, and the call controller 130 are performed by the processors 112, 122, and 132 of the BTS, the controller, and the call controller, respectively. Is performed.

The mobile location and authorization database 140 maintains a profile of each MS, such as the MS 102 that subscribes to communication services provided by the operator of the system 100. Each such MS's profile includes an MS identifier (mobile ID), such as the International Mobile Subscriber Identity (IMSI) associated with the MS, RF bands supported by the MS, and forwarding, short message service (SMS), caller identification (caller ID). And any subscription services provided by the communication system 100, such as the inter-band call direction change service, and subscribed to by the MS. Database 140 also maintains and tracks entitlement and mobility information for each such MS, including the registration of the MS and the location of the MS, such as the BS serving the MS, when the MS operates in communication system 100. When an MS, such as MS 102, attempts to originate a call within a coverage area serviced by call controller 130, the call controller responds to a request from a BS serving the MS in response to a request from a remote mobile location and authorization database ( 140 retrieves the profile of the MS and stores the profile of the MS in the local movement location and authorization database 136. In another embodiment of the present invention, the profile of the MS serviced by the call controller 130 may be stored locally in the mobile location and authorization database 136. In such an embodiment, when the MS attempts to make a call, the call controller 130 retrieves the profile of the MS from the database 136 in response to a request from the BS serving the MS.

Each RF band supported by BS 106 is associated with a forward link such as forward link 150 and a reverse link such as reverse link 152 of communication system 100. Each forward link is associated with and operates in one of multiple RF bands and includes a forward common signaling channel and a forward traffic channel. Each reverse link 152 is also associated with and operates in one of multiple RF bands and includes a reverse common signaling channel and a reverse traffic channel.

Communication system 100 includes a wireless communication system that supports multiple RF bands. In order to establish a connection with an external network (not shown) to which the MS 102 is connected to the infrastructure 104, the BS 106 operates according to well-known wireless telecommunication protocols. By operating in accordance with well-known protocols, a user of MS 102 can enable MS 102 to communicate with infrastructure 104 and establish an inbound link with an external network through the infrastructure. Communication system 100 is a 3GPP2 and TIA / EIA (Telecommunications Industry Association / Electronics Industry Association) IS-95B, IS-2000 providing CDMA (Code Division Multiple Access) and cdma 200 communication systems including IS-2001 air interfaces. It is desirable to operate in accordance with at least one of the IS-2000-A, IS-2000-B, IS-2000-C, IS-2000-D, and IS-2001-C (v1.0) standards. These standards define wireless telecommunications system operating protocols, including wireless system parameters and call processing procedures. However, those skilled in the art will appreciate that the communication system 100 may be a mobile communication globalization system (GSM) communication system, a time division multiple access (TDMA) communication system, a frequency division multiple access (FDMA) communication system, or an orthogonal frequency division multiple access (OFDM) communication system. It may operate according to any one of various wireless communication systems such as.

In communication system 100, MS 102 sends a call to infrastructure 104 over a reverse common signaling channel on reverse link 152 associated with the first RF band and is used to congest or allocate this band to the MS. When not possible, the infrastructure 104 determines if the MS can be allocated other RF bands before executing the call processing extensively. When the MS 102 can change direction between bands, that is, when it supports alternating RF bands and is allowed to change direction to such RF bands, these RF bands are also supported by the infrastructure, and this infrastructure Redirects the MS to a reverse signaling channel on the reverse link associated with the alternate RF band prior to performing extended call processing. Thus, the MS 102 does not need to automatically initiate a new access attempt in the second RF band when the first RF band is congested, thereby minimizing call setup time and multi-band when the first RF band is congested. Minimize user confusion about using the full functionality of Microsoft.

2A and 2B show a logic flow diagram 200 of steps executed by the communication system 100 upon allocating an RF band to the MS 102 during a call origination attempt by the MS in accordance with an embodiment of the present invention. When BS 106 and in particular BTS 110 receive a call origination request, preferably an origination request from MS 102 via a reverse common signaling channel on reverse link 152 associated with the first RF band (204). Logic flow diagram 200 begins (202). This request contains the mobile ID associated with the MS. In response to receiving the call origination request, BS 106 and, in particular, BTS 110 or controller 120, make a preliminary traffic allocation decision for the allocation of the traffic channel associated with the first RF band to MS 102 (206). . In addition, in response to receiving the call origination request, BS 106 and in particular BTS 110 or controller 120 may select an MS (with an RF band other than the alternate RF band, ie, the first RF band accessed by the MS). Determine whether to attempt switching 102 (208).

For example, BS 106 may determine whether to attempt to switch MS 102 to an alternate RF band, because the RF band to which MS 102 is accessed is congested, eg, forward link 150. ) Is crowded. As another example, BS 106 may determine to switch MS 102 to an alternating RF band to make the current RF communication more free for emergency communication. Those skilled in the art will recognize that there are numerous reasons for switching the MS 102 to an RF band other than the RF band that the MS currently accesses without departing from the principles and scope of the present invention.

When BS 106 determines that MS 102 does not switch to an alternate second RF band (208), BS, in particular controller 120, sends a service request, such as an AI CM service request, to MS 102. Request a service and pass it to call controller 130 which provides the mobile ID associated with the MS. In response to the service request, call controller 130 assigns a terrestrial circuit to the call, authenticates and verifies MS 102 based on the mobile ID included in the request received from the MS, and records the billing record associated with the call. Perform normal call processing, including starting (210). As part of the process of authentication and verification MS 102, call controller 130 downloads the entire profile of MS 102 from remote mobile location and authorization database 140 and moves location and authorization database 136. Store the profile locally in. In another embodiment of the present invention, the profile of the MS 102 is maintained in the movement location and authorization database 136, and the call controller 130 retrieves the profile of the MS from the database 136. The call controller then notifies BS 106 that the circuit has been allocated and MS 102 has been authenticated, typically by sending an Al allocation request to BS. In response to being informed of the MS 102's authentication and the assignment of the terrestrial circuit, the BS 106, in particular the BTS 110 or the controller 120, completes the assignment of the traffic channel to the MS 102 and calls 212. Proceeds as is well known. The logic flow 200 then ends (232).

When BS 106 determines to switch MS 102 to the second RF band (208), BS and in particular BTS 110 or controller 120 forward the modified service request to call controller 130. This service request is modified to include a request 214 for the infrastructure-maintained radio frequency (RF) traffic channel determination-related subscriber data associated with the MS. For example, BS 106 may request RF traffic channel determination-related subscriber data by including such a request to call controller 130 in the service request delivered by BS 106. For example, BS 106 may forward a modified version of the A1 CM service request to call controller 130, which is modified to include a request for RF traffic channel determination-related subscriber data. .

The RF traffic channel determination-related subscriber data includes data that allows the BS 106 to determine whether the MS 102 can be allocated to an RF band other than the RF band accessed by the MS. For example, traffic channel determination-related subscriber data may include RF band capabilities by the MS 102. As another example, a call direction change in which the communication system 100 automatically redirects a call from different subscription packages for system subscribers, such as a congested RF band initially accessed by the MS, to another uncrowded RF band. When including a subscription package that includes a service, the traffic channel-related subscriber data may include information about any such subscription package that is subscribed by a user of the MS.

In response to receiving the modified service request and determining that the request includes a request for traffic channel-related subscriber data, the call controller 130 executes the processed response procedure. That is, the call controller 130 is responsible for traffic channel determination-related subscribers from the profile of the MS 102 maintained in the infrastructure 104, in particular the mobile location and authorization database 136 or the mobile location and authorization database 140. The data is retrieved (216). In one embodiment of the present invention, the profile of the MS 102 is maintained in the movement location and authorization settings 140, and the call controller 130 downloads the profile of the MS from the database 140, which profile is the MS. Traffic channel determination-related subscriber data associated with the. The call controller 130 then stores the downloaded profile in the mobile location and authorization database 136 and retrieves only the portion of the profile that includes the associated traffic channel decision-related subscriber data from the database 136. In another embodiment of the present invention, the profile of the MS 102 is maintained in the mobile location and authorization database 136, where the call controller 130 retrieves only a portion of the profile of the MS from the database 136, The portion contains traffic channel decision-related subscriber data and this portion is smaller than the overall profile of the MS.

The call controller 130 then determines which traffic channel has been downloaded or retrieved to the BS 106 before performing any other call processing, such as allocating terrestrial circuits, beginning billing records, additional authentication / verification, and the like. Pass subscriber data (218). For example, call controller 130 may forward traffic channel decision-related subscriber data to BS 106 via a modified version of the A1 assignment request message, which may be traffic channel decision-related subscriber data. It is modified to include. In addition, based on the downloaded or retrieved traffic channel determination-related subscriber data, the call controller 130 determines 220 whether the MS 102 can be inter-band redirected, that is, the MS 102 is redundant. Determine whether the MS is a band MS, whether the MS 102 is allowed to be allocated another RF band, and whether the MS can support inter-band redirection to target the RF band of the infrastructure 104. When the MS is a multi-band MS that is allowed to be allocated to another RF band, that is, is capable of supporting the inter-band redirection to target the RF band of the infrastructure 104, the call controller 130 220 suspends execution of all other call processing such as allocation of terrestrial circuits, the start of billing record, and additional authentication and verification of MS 102.

Based on the RF traffic channel determination-related subscriber data, the BS 106 and in particular the BTS 110 or the controller 120 also support whether the MS 102 can be changed in interband direction, ie by the infrastructure 104. It is determined 224 that it is a dual-band MS that supports the second RF band and is allowed to redirect to such a band. When BS 106 determines that MS 102 is not interband oriented, BS 106 and in particular BTS 110 may optionally tear down 226 the call and terminate the MS's access attempt. . For example, the MS 102 may not support the second RF band, and other RF bands supported by the MS 102 may not be supported by the infrastructure 104 and / or the MS 102, in particular A user of the MS 102 may not subscribe to a subscription package that allows a change of orientation of the MS from an RF band initially accessed by the MS to an alternate RF band.

When BS 106 determines that MS 102 may be inter-band directional changed 224, BS 106 and in particular BTS 1110 or controller 120 may send a second direction change message to the MS by sending a second message. Reorient MS 102 to the RF band (228). For example, BS 106 extends the Channel Allocation Message (ECAM) over a forward common signaling channel of forward link 150 that assigns MS 102 to a signaling channel such as a paging / access channel in a second RF band. May be passed to the MS 102. ECAM messages are well known techniques and are described in detail in the TIA / EIA (Telecommunications Industry Association / Electronic Industry Association) IS-2000.5-C standard. In response to receiving the change of direction message, MS 102 automatically initiates 230 a new access attempt in the second RF band. For example, when BS 106 additionally supports the second RF band, MS 102 can initiate a new access attempt by forwarding a new outgoing message to BS 106 over the second RF band. As another example, when BS 106 supports a first RF band, MS 102 forwards a new outgoing message from another communication system 100 that supports the second RF band to another BS (not shown). This can initiate a new access attempt. The logic flow 200 then ends (232).

By retrieving the RF traffic channel decision-related data associated with the MS that is maintained by the infrastructure and that is, the MS 102 originating the call before performing the supplementary call CJL, the communication system 100 makes a facilitated direction change decision. to provide. The retrieval of RF traffic channel determination-related data is facilitated because the call controller 130 retrieves data from the database 136 before further call processing and without further retrieving the entire profile of the MS. This result facilitates or redirects the MS to a second RF band, which provides an accelerated process for accessing the direction change capability of the MS when the first RF band is congested. In addition, system resources are reserved because the call controller 130 stops further processing of calls originated by the MS when the MS 102 is a multi-band MS that may be redirected interband.
