摘要： A method and computer program for initiating a message to a radio access network include steps of: (404) detecting a request to transmit a probe message from a transmitter over an access channel to a radio access network; (406) calculating a transmit power for the probe message; (408) checking a condition that may result in failure to receive the probe message over the access channel by the radio access network; and (410) when the condition is determined to be true, then (412) reducing a message length of the probe message to generate a shorter probe message; (414) recalculating the transmit power to send the shorter probe message; and (416) transmitting the shorter probe message over the access channel at the recalculated transmit power.

摘要： A communication system provides for a handoff of a hybrid mobile station (MS) between a legacy network implementing a non-high rate packet data (non-HRPD) communication technology and a network implementing a high rate packet data (HRPD) communication technology. In one embodiment, the legacy network receives a handoff trigger and redirects the MS to the HRPD network. In other embodiments, the legacy network (or HRPD network) receives a handoff trigger, obtains an allocation of HRPD network (or non-HRPD network) resources from the HRPD network (or non-HRPD network), and informs the MS of the allocated HRPD network (or non-HRPD network) resources. Subsequent to the establishment by the HRPD network (or non-HRPD network) of a traffic channel with the MS, the non-HRPD network (or HRPD network) releases non-HRPD network (or HRPD network) RF resources associated with the MS. In still other embodiments, the handoffs may be controlled by a Mobile Switching Center.

摘要： A High Rate Packet Data (HRPD) wireless access network station (400) that accepting a data session handoff from a CDMA2000 1x base station. The wireless access network station (400) receives, from an access terminal (120), a location notification message with a valid Previous Access Network Identifier (PANID). The wireless access network station (400) further receives session parameters from a remote access network having a previous data session with the access terminal and determines if the PANID is consistent with the session parameters received from the remote access network. The wireless access network station (400) further has a data session controller (402,416) that, in response to determining the PANID is not consistent with the session parameters, establishes an RF traffic channel and connects a data session between the access terminal (120) and a Packet Data Serving Node (208) based upon the PANID received from the access terminal.

摘要： Various embodiments are described to address the need for reduced handoff delays associated with inter-AN (access network) HRPD (High Rate Packet Data)/1XEV-DO handoffs. The disclosed approach enables an AT (101) with an active packet data session to perform a hard handoff from a source AN (121, 221) to a target AN (122, 222) without having to force the data session dormant. Unlike known hard handoff approaches that involve coordination by a mobile switching center (MSC), the disclosed approach uses peer-to-peer signaling with no MSC involvement, such as that between source and target ANs or PCFs (131, 132, 231, 232). For example, data session information at the source side is transferred via new A13 messaging to the source entity's target-side peer to otherwise reduce signaling between the source and target equipment.

摘要翻译： 描述了各种实施例以解决对与AN（接入网络）HRPD（高速率分组数据）/ 1XEV-DO切换相关联的减少的切换延迟的需要。 所公开的方法使得具有活动分组数据会话的AT（101）能够执行从源AN（121,221）到目标AN（122,222）的硬切换，而不必强制数据会话休眠。 与涉及移动交换中心（MSC）协调的已知硬切换方法不同，所公开的方法使用没有MSC涉及的对等信令，例如源和目标AN或PCF之间的对等信令（131,132,231,232 ）。 例如，源侧的数据会话信息通过新的A13消息传送到源实体的目标端对等体，以减少源设备和目标设备之间的信令。
