An apparatus and method for improved data speeds for wireless device are discloses. The wireless device locates at a first location within a first cell, and detects a failure to acquire SIB of the first cell. A waiting period is started in response to the failure to prohibit selecting the first cell during the waiting period. After determining that the wireless device has left a vicinity of the first location in the first cell, the wireless device connects to the telecommunication network via the first cell before an expiration of the waiting period. According to the disclosure, the wireless device does not need to wait for the expiration of the waiting period before recom1ecting to the first cell. The wireless device does not need to connect to a lower data rate cell during the waiting period when the first cell is available. The user experience is improved.

A processing device and associated method are provided for receiving a connection request from an application running as a background process on a wireless communication device, and determining whether one or more random access procedure criteria of a random access procedure is met. The random access procedure establishes a communication connection of the wireless communication device for the connection request. In response to the determination that the one or more random access procedure criteria is met, at least one aspect of the random access procedure is restricted, utilizing one or more processors. Further, the random access procedure is performed with a restriction of the at least one aspect to establish the communication connection for the connection request.

The disclosure includes a method for rapidly recovering the speed of TCP transmission after a cross technology handover experienced by a mobile device. In the method, the mobile device receives a sequentially first TCP data packet after the cross technology handover completes via a TCP session between the mobile device and a remote TCP server, generates a first acknowledgement (ACK) associated with the sequentially first TCP data packet, where the first ACK comprises a first Selective ACK (SACK) option, removes the first SACK option from the first ACK when a gap exists between data in the sequentially first TCP data packet and data received before the cross technology handover occurs, and sends the first ACK without the first SACK option to the remote TCP server via the TCP session. Because the ACK is without the SACK option when the gap exists, the speed of TCP transmission will be recovered rapidly.

An apparatus, computer program, and method are provided for utilizing a particular radio access technology to connect to a telecommunication network before an expiration of a timer. A wireless communication device is provided including at least one hardware processor configured for sending a first request from the wireless communication device for connecting to a telecommunication network via a first base station for a first area. Such first base station implements a first radio access technology that has a first priority and a first data rate. In response to detecting a failure of the first request, a second radio access technology is utilized to connect to the telecommunication network before an expiration of a timer. Such second radio access technology has a second priority that is lower than the first priority and a second data rate that is lower than the first data rate. Further, in response to detecting that the wireless communication device has moved to a second area associated with a second base station before the expiration of the timer, a second request is sent via the second base station that implements the first radio access technology for utilizing the first radio access technology to connect to the telecommunication network before the expiration of the timer.

An apparatus, computer program, and method are provided for acceleration of a handover if mobile communication device signaling is degrading. Signal information is received in connection with a mobile communication device being serviced by a cell of a network. It is determined whether the signal information indicates that at least one aspect of a signaling in connection with the mobile communication device is degrading. An acceleration of a handover is conditionally caused in connection with the mobile communication device, if it is determined that the signal information indicates that the at least one aspect of the signaling in connection with the mobile communication device is degrading.

An apparatus, computer program, and method are provided for criteria-based conditional cell reselection. In operation, information is identified in connection with a mobile communication device being serviced by a first cell of a network utilizing a first frequency with a first priority.
