Abstract: A method and system is disclosed for including an IMSI in an EVDO access request. When an access terminal determines that any access request it makes will be sent to a micro-type base station, the access terminal will include its IMSI in any EVDO access request. When a micro-type base station receives an EVDO access request containing an IMSI of the requesting access terminal, the micro-type base station will use the included IMSI to establish and identify a data connection to a PDSN.

Abstract: An originating mobile station seeks to establish a push-to-talk (PTT) communication session with a destination mobile station. To do this, the originating mobile station transmits a first request message that requests the PTT session. Before receiving a predefined indication that the requested PTT session has been accepted, the originating mobile station transmits a first continuation message that includes first session description information to facilitate establishment of the PTT session. A PTT server receives the first request message and, before receiving the first continuation message, transmits to the destination mobile station a second request message that requests the PTT session. The PTT server then transmits a second continuation message that includes second session description information. The destination mobile station receives the second request message and, before receiving the second continuation message, transmits an acceptance message indicating acceptance of the requested PTT session.

Abstract: Disclosed herein is a method that enables a radio access network (RAN) to page more mobile stations concurrently. By reducing the size of the individual page record, more page records can fit within a general page message (GPM), and thus more mobile stations can receive page messages. One method of reducing the size of an individual page record is to reduce the size of the terminal IDs that page records carry. Currently, terminal IDs are globally unique, but they can be shortened if replaced with locally unique IDs. These locally unique IDs are unique for only mobile stations in a given paging area, unique for only mobile stations assigned to a given paging channel time slot, and/or unique for only mobile stations in a subgroup of mobile stations assigned to a given paging channel time slot. The number of mobile stations in any of these groups is smaller than the number of mobile stations in the global network. Therefore, the length of a terminal ID that is unique for only mobile stations in one of these groups can be shorter than a globally unique identifier.

Abstract translation: 这里公开了一种能够使无线接入网（RAN）同时寻呼更多移动台的方法。 通过减小单个页面记录的大小，更多的页面记录可以适合一般的页面消息（GPM），因此更多的移动站可以接收页面消息。 减小单个页面记录大小的一种方法是减小页面记录携带的终端ID的大小。 目前，终端ID是全局唯一的，但如果替换为本地唯一的ID，则可以缩短终端ID。 这些本地唯一的ID对于给定寻呼区域中的移动站是唯一的，对于仅分配给给定寻呼信道时隙的移动站是唯一的，和/或仅对分配给给定寻呼信道的移动站的子组中的移动站唯一 时隙。 这些组中的任何一个移动站的数量都小于全球网络中的移动站的数量。 因此，这些组中的一个中仅一个移动站唯一的终端ID的长度可以比​​全局唯一的标识符短。

Abstract: A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

Abstract: A method and system is disclosed for reactively managing dropped calls in a wireless communication system. A mobile station determines that it has experienced a dropped call. In response, the mobile station allows a user to continue communicating, such as by recording the user's speech, for instance. The mobile station may then play out the recorded speech to the user or to another call participant, such as upon reestablishment of the call.

Abstract: In a system where a first node provides a first area of TDD coverage on a first TDD carrier using a first TDD configuration and an adjacent second node provides a second area of TDD coverage on a second TDD carrier using a different second TDD configuration, the first node could additionally provide an area of FDD coverage on a first FDD carrier, including causing the area of FDD coverage to sit at least partially between the first and second areas of TDD coverage and therefore to define a spatial buffer between the first and second areas of TDD coverage. For instance, the first access node could restrict its service on the first TDD carrier to be for user equipment devices (UEs) that are relatively close to the first access node and could restrict its service on the first FDD carrier to be for UEs that are relatively far away from the first access node.

Abstract: A method and system for controlling application of TTI bundling on a carrier on which an access node provides service, the carrier defining air-interface resources. An example method includes detecting that at least a predefined threshold number of devices of a predefined class (e.g., IoT devices) are connected with the access node on the carrier. Further, the example method includes, responsive to the detecting that at least the predefined threshold number of devices of the predefined class are connected with the access node on the carrier, proactively reserving a portion of the air-interface resources for use to serve communications between the access node and the devices of the predefined class and, in view of the proactive reserving of the portion of the air-interface resources, imposing a reduction in the application of the TTI bundling by the access node on the carrier.

Abstract: A mechanism for controlling service of a user equipment device (UE), including (i) predicting that the UE will move sequentially through multiple zones of coverage of an access node that operates on a different respective set of one or more frequency bands in each zone of coverage and that has a respective radio-frequency (RF) circuitry quality as to each frequency band, (ii) based on the predicting, determining an RF-circuitry-quality score of the access node as an aggregate of the RF-circuitry-qualities of the access node as to the frequency bands on which the access node operates in the multiple zones of coverage through which the UE is predicted to move, and (iii) before the predicted movement of the UE through the multiple zones of coverage occurs, proactively using the determined RF-circuitry-quality score of the access node as a basis to control whether the UE is served by the access node.
