One embodiment of the present disclosure relates to a method for uplink SPS release. The method for operating a network node device comprises: determining whether or not there is a dynamically scheduled uplink transmission for a communication device in an uplink sub-frame where the communication device needs to perform an uplink SPS release; sending to the communication device, in response to determining that there is a dynamically scheduled uplink transmission for the communication device in the uplink sub-frame where the communication device needs to perform an uplink SPS release, a dynamic scheduling DCI message for the dynamically scheduled uplink transmission. At least one field of the dynamic scheduling DCI message is configured in a manner that the dynamic scheduling DCI implicitly indicates the uplink SPS release. The method further comprises sending to the communication device, in response to determining that there is no dynamically scheduled uplink transmission for the communication device in the uplink sub-frame where the communication device needs to perform an uplink SPS release, an uplink SPS release DCI message to explicitly indicate the uplink SPS release. According to an aspect of the present disclosure, there are provided corresponding methods and devices.

The processing circuit is configured to execute the instructions stored in the storage unit. The instructions a RRC layer of the communication device receiving system information from a cell of a network; the RRC layer informing an EPS mobility management (EMM) layer of the communication device that a User Plane EPS Optimization functionality (e.g., a resume/suspend functionality) is allowed in the cell, when the system information indicates that the User Plane EPS Optimization functionality is allowed; and the RRC layer informing the EMM layer that the User Plane EPS Optimization functionality is not allowed in the cell, when the system information indicates that the User Plane EPS Optimization functionality is not allowed.

Apparatuses, methods, and systems are disclosed for providing data connectivity with various types of data session continuity. One apparatus 200 includes a processor 205 that receives a data session request, identifies a required continuity type based on the data session request, and establishes a PDU session having the required continuity type. The required continuity type may be selected from a plurality of continuity type supported by a mobile communication network 312. In various embodiments, the apparatus 200 includes a transceiver 225 that communicates with the mobile communication network 312.

A technique relating to resource configuration in a wireless communication network. A terminal device in the wireless communication network receives information about supplemental resource from a source cell. Then the terminal device determines a time interval, in which the supplemental resource is available to the terminal device, in a transition period of a handover from the source cell to a target cell based on a timer associated with a random access procedure in the handover. In this way, the terminal device may use the supplemental resource during the handover.

Presented is a method for controlling network access for the mobile device. The method includes analyzing a first plurality of network parameters, collected by the mobile device, based on one or more local network policies. The method further includes receiving an update for the one or more local network policies from a policy server based on a second plurality of network parameters received by the policy server from a plurality of mobile devices. The method also includes rerouting data traffic for the mobile device from a first wireless network configuration to a second wireless network configuration based on the analyzing of the second plurality of network parameters and the update from the policy server. Rerouting data traffic for the mobile device may include maintaining a constant IP address utilizing a virtual network adapter within the mobile device to provide split tunneling over two or more network connections of the second wireless network configuration.

Methods and apparatus for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1X operation), a mobile device can place CDMA 1X voice calls while registered with the LTE network. However, since the LTE and CDMA 1X networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1X paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1X pages, overall LTE network performance is minimally affected.

Where a source of data has a time at which it is to transmit data, if it has data to transmit, for example as determined by a timer, this time is advanced when there is an active data connection. In this manner, rather than the data connection being torn down, and then immediately set up again, the data can be transmitted before the connection is torn down. In some embodiments, a history is maintained in terms of how long data connections are maintained. Then, once data transmission on an active connection ceases, the times are advanced, or not, depending on a likelihood that the connection will stay up for some further period of time.

Communication systems, such as an evolved packet system, may benefit from methods for addressing infrequent transmissions. In particular, certain communication systems in which machine type communication devices are deployed may benefit from a machine type communication feature for infrequent transmission. A method for providing such a feature can include negotiating at least one characteristic of a bearer. The method can also include deactivating the bearer based on the at least one characteristic.
