7 0 0 0 INTRODUCTION. General Description This chapter defines requirements for support of high speed packet data transmission capability on cdma000 spread spectrum systems. Packet data transmission is supported on cdma000 Traffic Channels using primary or secondary traffic. For packet data transmission on traffic channels using Service Option or Service Option, the Radio Link Protocol Type specified in C.S is used. This standard specifies a packet data bearer service for communication between terminal equipment and a packet data serving node (PDSN) via a base station/packet control function (BS/PCF). Packet data service options provide a means of establishing and maintaining Traffic Channels for packet data service. Service Option and Service Option are used to request packet data service through a PDSN supporting an Internet standard Point-to-Point Protocol (PPP) interface to network layer protocols (see.). Additional packet data service options may be defined in future revisions to select other types of PDSN resources or services.. Terms Auxiliary Service Instance. A packet data service instance that is not used to perform PPP negotiation (see []). An auxiliary service instance uses service option number. Base Station (BS). A fixed station used for communicating with mobile stations. Depending upon the context, the term base station may refer to a cell, a sector within a cell, or other part of the wireless system. BS. See base station. BS/PCF. The base station and packet control function considered as a single functional entity. CCPD. See Common Channel Packet Data. Common Channel Packet Data. A mode of operation in which the MS and BS only use Short Data Bursts transmitted on common channels to exchange packet data.

A mobile station will request a direct-to-dormant transition if it intends to use Common Channel Packet Data. Data Circuit Terminating Equipment (DCE). A DCE connects a DTE to the network. A typical DCE would be a V-series modem. cdma000 is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of GPP.

Inactive State When the packet data service is in the Inactive State, the mobile station does not provide packet data service. The means for determining when the packet data service enters the Active State are left to the mobile station manufacturer. When the packet data service enters the Inactive State from the Active State, if the Network Layer R m interface protocol option is selected, and the R m Link Layer interface is implemented using PPP, the MT should close the R m Link Layer connection....

The packet data service shall enter the Inactive State. If the base station initiates connection of an auxiliary service instance whose packet data service call control function is in the Null State and the packet data service option associated with this auxiliary service instance is connected, the auxiliary service instance s packet data service call control function shall enter the Connected State when the auxiliary service instance s call control instance enters the Conversation Substate.... Initialization State While the packet data service call control function is in the Initialization State, the mobile station shall perform the following: -

19 If the packet data service option is connected, the packet data service call control function shall enter the Connected State when the call control instance enters the Conversation Substate. If the mobile station requested a direct-to-dormant transition, and if the base station does not reject the request and also does not connect the service option, the packet data service call control function shall enter the Dormant State. If the packet data service call control function is associated with the main service instance, the packet data service shall enter the Inactive State if any of the following occur while the packet data service call control function is in the Initialization State: 0 The base station rejects the mobile station s request for a direct-to-dormant transition; or The packet data service option cannot be connected (e.g. service option rejected); or The mobile station enters the Mobile Station Initialization State; or The mobile station exits the System Access State and enters any state other than the Mobile Station Control on the Traffic Channel State. If the packet data service call control function is associated with an auxiliary service instance, the packet data service call control function shall enter the Null State if any of the following occur while the packet data service call control function is in the Initialization State: 0 The base station rejects the mobile station s request for a direct-to-dormant transition; or The packet data service option cannot be connected (e.g service option rejected). 0 If the packet data service enters the Inactive State, the packet data service call control function shall enter the Null State.... Connected State When the packet data service call control function enters the Connected State, the mobile station begins RLP initialization. While in the Connected State, the mobile station shall perform the following: If the packet data service option is disconnected, the mobile station shall perform the following: the mobile station shall set the packet data dormant timer to the value specified in.. and start the timer; the packet data service call control function shall enter the Dormant State. The mobile station shall maintain a packet data inactivity timer. The value of this timer shall not be less than 0 seconds. The timer should be reset whenever a non-idle RLP data frame is sent or received. If the packet data inactivity timer expires, the mobile station should disconnect the packet data service option. If the mobile station has determined that no further data will be exchanged with the base station prior to -

20 0 0 0 expiration of the packet data inactivity timer, the mobile station may disconnect the service option. If the packet data service call control function is associated with the main service instance and packet zone hysteresis is enabled (see..) and if the mobile station sends or receives user data, the mobile station shall set the packet zone hysteresis activation indicator to. If the packet data service enters the Inactive State, the packet data service call control function shall enter the Null State. When the amount of user data in the mobile station reaches an implementation defined threshold, the mobile station may request reverse high speed operation (see..).... Dormant State While the packet data service call control function is in the Dormant State, the mobile station shall perform the following: If the packet data service call control function is associated with the main service instance, the mobile station shall store the current value of SID, NID, and PACKET_ZONE_IDs.

21 0 If the mobile station determines that it is unlikely that further data will be exchanged with the base station within the time specified by the hysteresis activation timer, it may set the timer to 0. Otherwise, the mobile station shall set the hysteresis activation timer as follows: + If the base station indicated a value for the packet zone hysteresis activation timer, the mobile station shall set the timer to the value indicated by the base station. + If the base station did not indicate a value for the packet zone hysteresis activation timer, the mobile station shall set the timer to an implementationspecific value between 0 and 0 seconds. 0 After setting the packet data hysteresis activation timer, the mobile station shall start the timer and set the packet zone hysteresis activation indicator to 0. If the hysteresis activation timer is active and the mobile station determines that it is unlikely that further data will be exchanged with the base station before the expiry of the hysteresis activation timer, the mobile station may cancel the hysteresis activation timer. If the hysteresis activation timer is active and the packet zone list contains an entry with an active hysteresis timer for the current packet zone, the mobile station shall cancel the entry s packet zone hysteresis timer and shall remove the entry from the packet zone list. If the mobile station enters the Registration Access Substate (see []) due to timerbased registration, distance-based registration, zone-based registration, parameter change registration, or user zone registration, and if the packet zone list contains an entry with an active hysteresis timer for the current packet zone, the mobile station shall cancel the entry s packet zone hysteresis timer and shall remove the entry from the packet zone list.

If the packet data service call control function is associated with the main service instance and the mobile station detects a change in the serving system SID or NID When the packet zone hysteresis timer is set to 0, it is considered to expire immediately. Removing the entry from the packet zone list will trigger the mobile station to send an Origination Message (or equivalent) which serves as an implicit registration. When the Origination Message (or equivalent) is sent, it will cause the transmission of the Registration Message to be aborted prior to the initiation of the access attempt. -

22 0 when packet zone hysteresis is disabled, or when packet zone hysteresis is enabled but the mobile station does not support SID/NID hysteresis (see...). If the packet data service call control function is associated with the main service instance and the mobile station detects a non-zero PACKET_ZONE_ID s that is not currently stored in its packet zone list (see..) when packet zone hysteresis is disabled, or when packet zone hysteresis is enabled but the mobile station does not support SID/NID hysteresis (see...).

If the base station chooses to use a Short Data Burst to send the data, the base station should send the Short Data Burst according to... If the PCF requests the base station to connect a packet data service option, the base station should perform the following: If the mobile station is in Mobile Station Idle State, the base station should page the mobile station, requesting the packet data service option supplied by the PCF. The packet data service call control function should enter the Paging State. Mobile stations supporting applications that include higher-layer data retransmission protocols should always discard such data. -

The base station then performs the following: If the PCF rejects the packet data connection, the base station should not connect the requested service option, and should indicate to the mobile station that the requested service option has been rejected. If the PCF accepts the packet data connection, the base station should not connect the service option and should indicate to the mobile station that the service option has not been rejected. For example, by sending a Release Order with the ORDQ field set to indicate that the service option is rejected. -

25 If the PCF accepts the packet data connection and indicates to the base station that the service option should be connected, the packet data service call control function should enter the Initialization State Paging State When the base station packet data service call control function is in the Paging State, the base station should perform the following: If the base station receives a Page Response Message or a Reconnect Message containing the same packet data service option number that was used to page the mobile station, the packet data service call control function should enter the Initialization State. If the base station does not receive a Page Response Message or a Reconnect Message, the base station should inform the PCF that the request for the packet data service option has been rejected. The packet data service call control function should enter the Null State. If the base station receives a Page Response Message or a Reconnect Message with a service option that is different than the service option sent in the page, the base station should send a Release Order rejecting the requested service option. The base station should inform the PCF that the request for the packet data service option has been rejected. The packet data service call control function should enter the Null State.... Initialization State When the base station packet data service call control function enters the Initialization State, the base station should attempt to connect the packet data service option according to... If the packet data service option is connected, the packet data service call control function should enter the Connected State. If the packet data service option cannot be connected, the base station should perform the following: If the mobile station does not support concurrent services signaling, the base station should disconnect the call. The base station should inform the PCF that the mobile station has rejected the connection attempt. The packet data service call control function should enter the Null State. For example, by sending a Release Order with the ORDQ field set to indicate a normal release. This includes receiving a Page Response Message or a Reconnect Message with the service option set to zero which indicates that the mobile station rejected the service option sent in the page. -

26 Connected State When the base station packet data service call control function enters the Connected State, the base station should perform the following: The base station should inform the PCF that the packet data service option has been connected. The base station should perform RLP initialization. Upon completing RLP initialization, the base station should transfer octets in sequence between the base station and the PCF. If the PCF requests the base station to disconnect the packet data service option, the base station should perform the following: The base station should disconnect the packet data service option. If the mobile station does not support concurrent services signaling, the base station should disconnect the call. The packet data service call control function should enter Null State. While the packet data service call control function is in the Connected State, the base station may maintain a packet data inactivity timer. The timer should be reset whenever non-idle RLP data frames are sent or received. If the packet data inactivity timer expires, or if the base station chooses to disconnect the packet data service option before the timer expires, the base station should perform the following: The base station should disconnect the packet data service option. The base station should inform the PCF that the packet data service option has been disconnected. The packet data service call control function should enter the Null State... Initialization and Connection of Packet Data Service Options The mobile station shall initiate connection of a packet data service option by requesting a packet data service option in a Page Response Message, a Reconnect Message, an Enhanced Origination Message, or an Origination Message. When the mobile station sends an Origination Message or an Enhanced Origination Message it shall perform the following: The mobile station shall indicate whether it has data to send (i.e., by setting the DRS bit in the message sent by the mobile station). The mobile station shall indicate if a direct-to-dormant transition is requested (e.g., by setting the SDB_DESIRED_ONLY bit in the message sent by the mobile station ). If this connection attempt is associated with the main service instance, the mobile station shall perform the following: A mobile station that intends to use Common Channel Packet Data (CCPD, see []) will request a direct-to-dormant transition by setting the SDB_DESIRED_ONLY bit in the Origination Message. -0

27 0 The mobile station shall request service option number in the message sent by the mobile station. If the mobile station has stored a value of SID and if the stored value of SID is different than the current value of SID, the mobile station shall include the stored value as the value of the previous SID. Otherwise, the mobile station shall not include the stored value. If the mobile station has stored a value of NID and if the stored value of NID is different than the current value of NID, the mobile station shall include the stored value as the value of the previous NID. Otherwise, the mobile station shall not include the stored value. If packet zone based reconnection is enabled and if the mobile station has stored a value of PACKET_ZONE_IDs and if the stored value of PACKET_ZONE_IDs is different than the current value of PACKET_ZONE_IDs, the mobile station shall include the stored value as the value of the previous packet zone identifier. Otherwise, the mobile station shall not include the stored value. 0 0 If this connection attempt is associated with an auxiliary service instance, the mobile station shall request service option number in the message sent by the mobile station. When the mobile station sends an Origination Message, a Reconnect Message, or a Page Response Message and the connection attempt was initiated while the packet data service call control function was in the Dormant State,, the mobile station shall perform the following: If the mobile station is allowed to use SYNC_ID, and has stored a non-null SYNC_ID value that corresponds to a service configuration that is the same as the mobile station s requested service configuration, the mobile station shall include the SYNC_ID in the Origination Message, the Reconnect Message or the Page Response Message. If the mobile station packet data service call control function is in the Dormant State, the mobile station shall set the SR_ID field to the value assigned to the last packet data service option connection for this packet data service. After initiating connection of a packet data service option, the mobile station connects the service option as specified in Mobile Station Procedures Packet data service options shall be negotiated and connected using the service configuration and negotiation procedures defined in []. For any packet data service option, the mobile station shall not propose a service configuration whose attributes are inconsistent with the valid service configuration attribute table for the service option. The mobile station shall not accept a service configuration whose attributes are inconsistent with the valid service configuration attribute table for the service option. The default service configuration for the packet data service option shall be as shown in the valid service configuration attribute table for the service option. -
