Abstract: A method for managing access channel traffic during congested network conditions is disclosed. A wireless connection device (WCD) sends a service request to a particular base station for a particular quantity of network resources. Upon the particular base station determining that it is too loaded with network traffic to accommodate the service request, the base station saves an indication of the WCD's connection request, and responds with a communication to instruct the WCD to idle and wait for a page from the base station. The WCD, upon receiving the communication, does not send a service request for a greater quantity of network resources than the particular quantity until the WCD receives a page. Once the base station determines it has sufficient network resources to allocate to the WCD, the base station sends a page to the WCD, which causes the WCD to send another service request.

Abstract: A primary mobile station engaged in a communication session via a radio access network (RAN) may receive forward link communications over a forward link channel and transmit reverse link communications over a reverse link channel. If the quality of the communication session degrades, the primary mobile station may involve a secondary mobile station by establishing a short-range wireless communication link with the secondary mobile station, e.g., using Bluetooth™, IEEE 802.11, or other wireless communication protocol. The primary mobile station may then transmit reverse link communications to the RAN over the reverse link channel and also transmit the reverse link communications to the secondary mobile station, via the short-range wireless communication link, for transmission to the RAN. The RAN may receive the reverse link communications from the primary and secondary mobile stations as two distinct reverse link signals, which the RAN may combine together to achieve a diversity gain.

Abstract: A wireless network includes first-configuration sectors with a first frequency assignment and second-configuration sectors with a second frequency assignment. When served by a first-configuration sector that borders a second-configuration sector, the mobile station receives (i) a neighbor list that identifies neighbor sectors of the primary sector, including the second-configuration sector, (ii) a primary-sector reference distance between a transmitter for the primary sector and a reference point in the primary sector, and (iii) a neighbor-sector reference distance between a transmitter for the second-configuration sector and the reference point. Based on the reference distances, the mobile station calculates a border distance between the primary sector's transmitter and a border between the sectors. The mobile station compares its distance from the primary sector's transmitter to the primary-sector reference distance and/or border distance. Based on the comparison, the mobile station selects a scanning algorithm that determines when to scan for the second-configuration sector.

Abstract: Disclosed is a method and corresponding apparatus to make use of hybrid-ARQ repetition factors as a way to differentiate service quality to various mobile terminals. Depending on a mobile terminal's subscription service class, such as the mobile terminal's PLMN, the mobile terminal may be made to use a particular hybrid-ARQ repetition factor. For instance, a mobile terminal of a high service class may be made to use a low hybrid-ARQ repetition factor, which may help the mobile terminal experience less downlink transmission delay and thus a higher downlink data rate. Whereas, a mobile terminal of a low service class may be made to use a high hybrid-ARQ repetition factor, which may cause the mobile terminal to experience more downlink transmission delay and thus a lower downlink data rate, and may further free up downlink transmission resources to facilitate better service for other mobile terminals.

Abstract: An inter-frequency handoff of a mobile station engaged in a call via wireless network is effected by gradually changing a carrier frequency of a forward link signal from a first-channel frequency, corresponding to a first frequency channel, to a second-channel frequency, corresponding to a second frequency channel. Initially, a first transmitter in the wireless network transmits the forward link signal in the first frequency channel. A second transmitter then transmits the forward link signal while changing the carrier frequency from the first-channel frequency to the second-channel frequency at a specified tuning rate. The tuning rate may be dynamically adjustable in response to requests from the mobile station. Once the second-channel frequency is reached, a third transmitter continues transmitting the forward link signal in the second frequency channel. The mobile station may also gradually change the carrier frequency of the reverse link signal that it transmits for the call.

Abstract translation: 通过无线网络进行呼叫的移动台的频率间切换通过将来自对应于第一频道的第一频道频率的前向链路信号的载波频率逐渐变化为第二频道频率来实现， 对应于第二频道。 最初，无线网络中的第一发射机在第一频率信道中发送前向链路信号。 第二发射机然后在指定的调谐速率下将载波频率从第一信道频率改变到第二信道频率的同时发送前向链路信号。 响应于来自移动台的请求，调谐速率可以是动态可调节的。 一旦达到第二信道频率，第三发射机继续在第二频道中发射前向链路信号。 移动台还可以逐渐地改变其为呼叫发送的反向链路信号的载波频率。

Abstract: A radio access network (RAN) determines whether transmission time interval (TTI) bundling is warranted for a wireless communication device (WCD) based on at least a power headroom report from the WCD. In response to determining that TTI bundling is warranted, the RAN selects a TTI bundle size, N, for the WCD and instructs the WCD to use the selected TTI bundle size. The TTI bundle size, N, could be selected from among a set of predefined values, such as N=2, N=3, and N=4. The selection could be based on various factors, such as a utilization of an uplink shared channel, a re-transmission rate of the WCD, and/or a remaining battery life of the WCD.

Abstract: Disclosed herein are methods and systems that may help to determine and/or adjust parameters for zone-based paging over CDMA paging channels, based on the prevalence of devices that are configured for enhanced circuit switch fallback (eCSFB) in one or more paging zones. For example, a switch in a radio access network (RAN) may: (a) determine a respective measure of CSFB-device prevalence in one or more paging zones in the RAN, (b) use the respectively determined measure of CSFB-device prevalence in at least one of the paging zones as a basis to determine one or more parameters for zone-based paging in the at least one of the paging zones, and (c) apply the one or more determined parameters for zone-based paging in the at least one of the paging zones.

Abstract: A method, apparatus, and system for helping to manage advanced handoff to a coverage area based on correlation with a geographic region. A mobile station determines that it is in or approaching a defined geographic region, and the mobile station determines from correlation data that the geographic region is correlated with a particular cellular coverage area. The mobile station therefore requests handoff to the cellular coverage area and provides an advanced-handoff indication to cause the serving radio access network to maintain assignment of a radio connection in the coverage area longer than the network would normally, to help allow time for the mobile station to arrive at the coverage area and begin communicating on the radio connection with the network.

Abstract: Various embodiments are described for redirecting a mobile station via a traffic channel. In one embodiment, a first RAN receives a request from a mobile station to establish a traffic channel between the mobile station and the first RAN for use in a communication session. The first RAN makes a determination to not establish the communication session, but nevertheless establishes the requested traffic channel after making the determination. Then, without establishing the communication session, the first RAN redirects the mobile station via the established traffic channel to a second RAN. By establishing the traffic channel even though the RAN may be unable (or unwilling) to allow the mobile station to establish the communication session, the RAN is able to control the behavior of the mobile station in the event that the RAN cannot establish the requested communication session.
